A Tomsk Polytechnic University study reveals how topological vortices found in low-dimensional materials can be both displaced and erased and restored again by the electrical field within nanoparticles. This may open exciting opportunities for memory devices or quantum computers in which information will be encrypted in the characteristics of topological vortices.(Vortices in nanoparticles exposed by the electrical field. Credit: Tomsk Polytechnic University (TPU))Scientists from TPU and international collaborators have discovered unusual self-organization of atoms in the volume of nanoparticles and have learned to control it via an electric field. Such controlled nanoparticles can be used to generate capacious non-volatile random access memory (NRAM), quantum computers and other next-generation electronics. The main author is Dmitriy Karpov, engineer of the Department of General Physics, TPU, who explains that in modern materials science, the defects of matter are divided into two large groups. The first group includes classical, well-studied defects, when atoms in matter are mechanically disordered, i.e., atoms are either removed or inserted into the lattice. In the other group, the spatial organization of the lattice itself changes and such defects are called topological. Topological defects can strongly influence matter, making it superfluid or superconductive, and therefore, it is very important to study them. Topological defects can be found only in low-dimensional materials—two-dimensional nanorods and nanofilms (just several atoms thick) and one-dimensional nanodots or nanoparticles, which are spherical particles consisting of several tens or hundreds of identical atoms. "One of the important topological defects is a topological vortex which looks like a discernible twisting caused by a small displacement of all atoms. The vortex core is a nanostrand which can be both displaced by the field, and erased and restored again within nanoparticles," explains Edwin Fohtung, Professor of Los Alamos National Laboratory and New Mexico State University . The scientists studied barium titanate nanoparticles whose internal structure was visualized with the help of penetrating X-ray radiation from the synchrotron Advanced Photon Source (Chicago, USA). They obtained an image of the volume of nanoparticles with a resolution of 18 nanometers, which enabled them to analyze the slightest changes in the structure. As a result, the researchers showed that an external electric field can displace the core of the topological vortex inside the nanoparticle, and when the field is removed, it returns to its original position. Modern components of electronics are gradually becoming smaller. This can significantly influence the efficiency of devices, which will be significantly reduced due to quantum effects. One way to circumvent these limitations is to use topological vortices. Thus, they can be used to generate high density NRAM or quantum computers in which information will be encrypted in the characteristics of topological vortices. "All in all, the possibility to control and adjust topological vortices in nanoparticles is important for the creation of new electronics," concludes Dmitriy Karpov. Further reading>>>Topological defectA topological defect can be proven to exist[when?] because the boundary conditions entail the existence of homotopically distinct solutions. Typically, this occurs because the boundary on which the conditions are specified has a non-trivial homotopy group which is preserved in differential equations; the solutions to the differential equations are then topologically distinct, and are classified by their homotopy class. Topological defects are not only stable against small perturbations, but cannot decay or be undone or be de-tangled, precisely because there is no continuous transformation that will map them (homotopically) to a uniform or "trivial" solution. Reference>>>KY259-BB910KY259-CXA1512MKY32-K9T1G08U0M-YIBO 

Every time you want to create a printed circuit board (PCB), you need to design holes, pads, and traces for your circuit. Then you send this design to a manufacturer or etch it yourself. What if you want to create a circuit board by yourself but it sounds hard? Don't worry, there are many free and affordable tools available that will help you do this. There are just a few steps you need to go through, and anyone can do it – even if you have no prior experience.I What is a PCB?According to Wikipedia, a printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads, and other features etched from copper sheets laminated onto a non-conductive substrate. Components (e.g., capacitors, resistors, or active devices) are generally soldered onto the PCB. Advanced PCBs may contain components embedded in the substrate, and modern designs can include multiple layers (from single-layer to 50+ layers for complex applications).Printed circuit boardWould you like to make your own smart device? Or IoT controller? Or robot? Or drone? Well, then you would want to make a printed circuit board. PCBs are the foundation of virtually all modern electronics!A printed circuit board is typically made from FR-4 (Flame Retardant 4), a composite material made of woven fiberglass cloth with an epoxy resin binder that is flame resistant. While green is the traditional and most common color due to the green solder mask, PCBs now come in various colors including blue, red, black, white, yellow, and even matte black for aesthetic purposes. The solder mask protects the copper traces from oxidation and prevents solder bridges during assembly.On the board, there are components. Initially, the PCB is bare, but you solder the components onto the board following your design. Modern PCBs can use through-hole technology (THT) or surface-mount technology (SMT), with SMT being more common in contemporary designs due to its compact size and automated assembly capabilities.II How to Make a Printed Circuit Board?To make a printed circuit board you need to:1. Design schematics2. Create the PCB layout3. Generate manufacturing files (Gerber files)4. Get the board manufactured and assembled2.1 Design SchematicsThe first and most important step in PCB design is to start with your schematics. This is the blueprint of your circuit that shows how all components connect electrically.Before you start drawing traces and placing components, you need to know what circuit you want to build. You need to find or design schematics for your circuit and choose appropriate PCB design software. Popular options in 2025 include:KiCad - Free, open-source, and very powerfulEasyEDA - Free, web-based with integrated manufacturingAltium Designer - Professional-grade (paid)Eagle (Autodesk) - Popular hobbyist choice with free tierFusion 360 Electronics - Integrated with 3D CAD (paid)CircuitMaker - Free community-driven platform2.2 Create the PCB LayoutStart by drawing your schematic diagram into the software you have chosen. You need to define the connections (nets) between different components.This process involves placing component symbols and connecting them with wires that represent electrical connections. Modern PCB software will check for electrical rule violations (ERC - Electrical Rule Check) to catch errors early.Schematic design exampleNext, you transfer your schematic into a physical PCB layout. This involves:Component placement - Arranging components efficiently on the boardRouting traces - Drawing copper connections between padsPower and ground planes - Creating solid copper areas for power distributionDesign rule checking (DRC) - Ensuring your design meets manufacturing constraintsDrawing PCBs is both technical and artistic. Take your time and follow PCB design best practices:Keep traces as short as possible, especially for high-frequency signalsMaintain proper trace width for current requirements (use trace width calculators)Provide adequate spacing between traces (typically 6-8 mils minimum)Use ground planes to reduce noise and improve signal integrityConsider thermal management for power componentsPlace decoupling capacitors close to IC power pinsPCB layout exampleWill you put the circuit board in an enclosure? Consider the mechanical constraints: tall components might need specific placement, mounting holes must align with your enclosure, and connectors should be accessible. Print out your board design at 1:1 scale to verify physical fit before manufacturing.2.3 Manufacturing Your PCBWhen you finish your layout, it's time to prepare your design for manufacturing. You'll need to generate Gerber files (the industry standard format) and a drill file. Most PCB software can export these automatically.Home Etching vs. Professional Manufacturing:Home Etching:Pros: Immediate results, good for learning, no minimum order quantityCons: Limited to single or double-layer boards, requires chemicals (ferric chloride or cupric chloride), lower precision, manual drilling required, no solder mask or silkscreen, time-consumingProfessional Manufacturing (Recommended for 2025):Pros: High quality, multi-layer capability, solder mask and silkscreen included, plated through-holes, very affordable (as low as $2-5 for small boards), quick turnaround (2-7 days)Cons: Requires waiting for shipping, minimum order quantities (though often just 5 pieces)Popular PCB Manufacturers in 2025:JLCPCB - Very affordable, fast turnaround, assembly services availablePCBWay - Good quality, competitive pricing, excellent customer serviceOSH Park - USA-based, high quality, purple PCBsALLPCB - Budget-friendly optionEurocircuits - European manufacturer, excellent qualitySeeed Studio - Fusion PCB service, good for prototypesMany manufacturers now offer PCB assembly services (PCBA), where they'll solder the components for you. This is increasingly affordable and saves significant time, especially for SMT components.Frequently Asked Questions (FAQ)1. How much does it cost to make your own circuit board?As of 2025, PCB manufacturing costs have decreased significantly. For prototypes, you can get simple PCBs manufactured for as little as $2-5 for 5 pieces (100mm x 100mm or smaller). More complex boards with multiple layers, special materials, or larger sizes will cost more. PCB assembly costs typically range from $0.50 to $5 per component placement, depending on component type and quantity. For a complete assembled board, expect to pay $20-100 for small quantities, with costs decreasing significantly for larger production runs (hundreds or thousands of units).2. How do you design and specify printed circuits?The PCB design process follows these steps:Schematic capture - Create the electrical circuit diagramSimulation - Verify circuit functionality (optional but recommended)Component selection - Choose specific parts with appropriate footprintsBoard setup - Define board dimensions, layers, and design rulesComponent placement - Position components strategicallyRouting - Connect components with copper tracesPower plane design - Create ground and power distribution layersDesign rule check (DRC) - Verify manufacturabilityGenerate manufacturing files - Export Gerber and drill filesCreate BOM - Bill of Materials for component procurementAssembly documentation - Create assembly drawings and pick-and-place files3. What does a printed circuit board do?A printed circuit board serves two primary functions: it provides mechanical support for electronic components and creates electrical connections between them using conductive copper pathways. The PCB eliminates the need for point-to-point wiring, making electronic devices more reliable, compact, and manufacturable at scale. Modern PCBs also provide electromagnetic shielding, heat dissipation, and can integrate additional features like impedance-controlled traces for high-speed signals, embedded components, and flexible or rigid-flex sections.4. What is a printed circuit board called?Printed circuit boards are known by several names:PCB - Most common abbreviationPrinted Wiring Board (PWB) - Emphasizes the wiring aspectPrinted Circuit Assembly (PCA) - When components are already mountedPrinted Circuit Board Assembly (PCBA) - Fully assembled boardCircuit Board - General termThe term "printed" refers to the manufacturing process where the circuit pattern is printed onto the board, though modern manufacturing uses photolithography rather than literal printing.5. What is the difference between PCB and PWB?The terms PCB (Printed Circuit Board) and PWB (Printed Wiring Board) are often used interchangeably, but there's a subtle distinction:PWB typically refers to the bare board with only copper traces, pads, and holes - no components mountedPCB can refer to either the bare board or the assembled board with componentsPCBA or PCA specifically refers to the assembled board with all components solderedIn practice, most people use "PCB" to refer to both bare and assembled boards, with context determining the meaning.6. What is a printed circuit board made of?PCBs consist of several layers:Substrate - Usually FR-4 (fiberglass-reinforced epoxy), but can be FR-1, FR-2, CEM-1, CEM-3, polyimide (for flexible PCBs), aluminum (for LED boards), or Rogers material (for high-frequency applications)Copper layers - Typically 1 oz/ft² (35 μm) or 2 oz/ft² (70 μm) thickness, laminated to the substrateSolder mask - Protective polymer layer (usually green, but available in other colors) that prevents solder bridges and protects copper from oxidationSilkscreen - White (or other color) ink layer showing component designators, logos, and other markingsSurface finish - Protects exposed copper pads; options include HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), OSP (Organic Solderability Preservative), or immersion silver/tin7. What does PCB stand for?PCB stands for Printed Circuit Board. It's the foundation of modern electronics, providing both mechanical support and electrical connections for electronic components. PCBs replaced earlier point-to-point wiring and wire-wrap construction methods, enabling the mass production of reliable, compact electronic devices. The "printed" aspect refers to the manufacturing process where circuit patterns are created using photolithographic techniques, similar to how photographs are developed.8. Why are PCBs green?PCBs are traditionally green due to the color of the solder mask - a protective coating applied over the copper traces. The green color became standard for several reasons:Historical - Early solder mask materials naturally produced a green colorVisibility - Green provides good contrast for inspection, making it easier to see traces and identify defectsEye strain - Green is easier on the eyes during prolonged inspection and assembly workCost - Green solder mask is the most common and therefore least expensiveHowever, modern PCBs come in many colors: blue, red, black, white, yellow, purple, and even matte black. Color choice is now often aesthetic, though some colors (like black) can make inspection more difficult. High-end products often use black PCBs for a premium appearance, while purple has become popular in the maker community.9. How do you choose a PCB material?PCB material selection depends on your application requirements:By Application Type:Standard/General Purpose - FR-4 (most common, good for frequencies up to 1-2 GHz)High Frequency/High Speed (>2 GHz) - Rogers RO4003C, RO4350B, or Isola materials with controlled dielectric constantFlexible Circuits - Polyimide (Kapton) or polyesterRigid-Flex - Combination of FR-4 and polyimideLED/High Power - Aluminum or copper core for better heat dissipation (Metal Core PCB - MCPCB)High Temperature - Polyimide or high-Tg FR-4 (Tg > 170°C)Low Cost - FR-1, FR-2, or CEM-1 (phenolic paper-based)Key Material Properties to Consider:Dielectric constant (Dk) - Affects signal speed and impedanceLoss tangent (Df) - Signal loss at high frequenciesGlass transition temperature (Tg) - Maximum operating temperatureThermal conductivity - Heat dissipation capabilityCoefficient of thermal expansion (CTE) - Dimensional stability with temperature changesMoisture absorption - Affects reliability in humid environments10. Why do we use PCB instead of breadboard circuits?While breadboards are excellent for prototyping, PCBs offer significant advantages for final products:Advantages of PCBs over Breadboards:Reliability - Permanent solder connections vs. friction contacts that can loosenDurability - Resistant to vibration, shock, and environmental factorsCompactness - Much smaller footprint, especially with SMT componentsPerformance - Lower parasitic capacitance and inductance, better for high-frequency circuitsCurrent capacity - Wider traces can handle more current safelyReproducibility - Identical boards can be manufactured consistentlyProfessional appearance - Clean, polished look for commercial productsCost-effective at scale - Very cheap per unit in production quantitiesHeat management - Can integrate heat sinks, thermal vias, and metal coresEMI/EMC compliance - Better electromagnetic compatibility through proper grounding and shieldingWhen to Use Each:Breadboard - Initial prototyping, learning, testing concepts, temporary circuitsPCB - Final products, permanent installations, high-frequency circuits, production quantities, professional projectsConclusionCreating your own PCB has never been more accessible.

Today I want to share a project of making a simple automatic street light controller using relay and LDR I found in circuitdigest with you.   You have seen street light which automatically gets turned on in the night and gets turned off in the morning or day time, there are sensors who senses the light and control the light accordingly. These Street lights are an important project in smart cities.   So here in this project, we are going to make a Simple Automatic Street Light Controller Using Relay and LDR. This circuit is very simple circuit and can be built with Transistors and LDR, you don’t need any op-amp or 555 IC to trigger the AC load. Here we have used an AC bulb as street light. Some applications of this circuit are street light controlling, home/office light controlling, day and night indicators, etc.   Components Required:   Transistor BC547 -2 LDR (Light Dependent Resistor) Relay Resistor 1k 100k Potentiometer Power Supply 12v -1 Connecting wires Jumper wires Screw terminal Block 2 pin or 3 pin Bread Board or Perf Board 1n4007 Diode AC supply AC Load or Bulb   Here you may want to know: what is LDR? LDRs are made from semiconductor materials to enable them to have their light sensitive properties. There are many types but one material is popular and it is cadmium sulphide (CdS). These LDRs or PHOTO REISTORS works on the principle of “Photo Conductivity”. Now what this principle says is, whenever light falls on the surface of the LDR (in this case) the conductance of the element increases or in other words the resistance of the LDR falls when the light falls on the surface of the LDR. This property of the decrease in resistance for the LDR is achieved because it is a property of semiconductor material used on the surface. LDR (Light Dependent Resistor)   Circuit Diagram and Explanation:   Below is the circuit diagram of this Light sensing Street Light:       In this project, we have used an LDR (Light Dependent Resistor) which is responsible for detecting light and darkness. The resistance of LDR increases in darkness and reduces in presence of light. This circuit is same as a Dark Detector or Light Detector Circuit, only here we have replaced simple LED with a AC load, using a Relay. Two BC547 NPN transistors are used to drive the relay. Automatic Street Light circuit using LDR and relay   Whenever light falls over LDR its resistance get decreased and transistor Q1 turns ON and collector of this transistor goes LOW, and this makes the second transistor turns OFF due to getting a LOW signal at its base, so relay also remain turned OFF due to second transistor.   Now whenever LDR senses Darkness, mean no light, then transistor Q1 turned ON due to increase in the resistance of LDR which is responsible for voltage drop at the base of Q1. Due to a LOW signal at the Q1 base, Q2 transistor gets a HIGH signal from the collector of Q1 and turns ON the relay. Relay turned ON the AC load that is connected to relay. A 10K pot is also used for setting up the sensitivity of the circuit.   So this is how automatic Street Lights turns on in the night and turn off in the day, and below is the effect pictures. >>>>>                                                       > >>>>   Ref.

Access to clean, safe water is one of the world’s pressing needs, yet today’s water distribution systems lose an average of 20 percent of their supply because of leaks. These leaks not only make shortages worse but also can cause serious structural damage to buildings and roads by undermining foundations, which is a great loss.Many property losses experienced by business owners involve water damage caused by leaky pipes. Water can be very destructive whether it seeps from a loose fitting or gushes from a ruptured main.Unfortunately, leak detection systems are expensive and slow to operate — and they don’t work well in systems that use wood, clay, or plastic pipes, which account for the majority of systems in the developing world. Now, a new system developed by researchers at MIT could provide a fast, inexpensive solution that can find even tiny leaks with pinpoint precision, no matter what the pipes are made of. The system, which has been under development and testing for nine years by professor of mechanical engineering Kamal Youcef-Toumi, graduate student You Wu, and two others, will be described in detail at the upcoming IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) in September. Meanwhile, the team is carrying out tests this summer on 12-inch concrete water-distribution pipes under the city of Monterrey, Mexico. The system uses a small, rubbery robotic device that looks something like an oversized badminton birdie. The device can be inserted into the water system through any fire hydrant. It then moves passively with the flow, logging its position as it goes. It detects even small variations in pressure by sensing the pull at the edges of its soft rubber skirt, which fills the diameter of of the pipe.(The fast, inexpensive robotic device that developed by engineers from MIT can find even tiny leaks in pipes with pinpoint precision, no matter what the pipes are made of.)This device contains two parts: "skirt" sensor and soft body drone. It is then retrieved using a net through another hydrant, and its data is uploaded. No digging is required, and there is no need for any interruption of the water service. In addition to the passive device that is pushed by the water flow, the team also produced an active version that can control its motion.Monterrey itself has a strong incentive to take part in this study, since it loses an estimated 40 percent of its water supply to leaks every year, costing the city about $80 million in lost revenue. Leaks can also lead to contamination of the water supply when polluted water backs up into the distribution pipes. The MIT team, called PipeGuard, intends to commercialize its robotic detection system to help alleviate such losses. In Saudi Arabia, where most drinking water is provided through expensive desalination plants, some 33 percent is lost through leakage. That’s why that desert nation’s King Fahd University of Petroleum and Minerals has sponsored and collaborated on much of the MIT team’s work, including successful field tests there earlier this year that resulted in some further design improvements to the system, Youcef-Toumi says. DKNY CEO Caroline Brown, said “PipeGuard has created a simple, pragmatic and elegant solution to a complex problem. … This robot is a great example of utilizing smart design to simplify complexity and maximize efficiency.”

Modern life will be almost unthinkable without transistors. They are the ubiquitous building blocks of all electronic devices: each computer chip contains billions of them. However, as the chips become smaller and smaller, the current 3D field-electronic transistors (FETs) are reaching their efficiency limit. A research team at the Center for Artificial Low Dimensional Electronic Systems, within the Institute for Basic Science (IBS), has developed the first 2D electronic circuit (FET) made of a single material. Published on Nature Nanotechnology, this study shows a new method to make metal and semiconductor from the same material in order to manifacture 2D FETs. Faster electronic device architectures are in the offing with the unveiling of the world’s first fully two-dimensional field-effect transistor (FET) by researchers with Lawrence Berkeley National Laboratory (Berkeley Lab). Unlike conventional FETs made from silicon, these 2D FETs suffer no performance drop-off under high voltages and provide high electron mobility, even when scaled to a monolayer in thickness.（Berkeley Lab researchers fabricated the first fully 2D field-effect transistor from layers of molybdenum disulfide, hexagonal boron nitride and graphene held together by van der Waals bonding.） Ali Javey, a faculty scientist in Berkeley Lab’s Materials Sciences Division and a UC Berkeley professor of electrical engineering and computer science, led this research in which 2D heterostructures were fabricated from layers of a transition metal dichalcogenide, hexagonal boron nitride and graphene stacked via van der Waals interactions. In simple terms, FETs can be thought as high-speed switches, composed of two metal electrodes and a semiconducting channel in between. Electrons (or holes) move from the source electrode to the drain electrode, flowing through the channel. While 3D FETs have been scaled down to nanoscale dimensions successfully, their physical limitations are starting to emerge. Short semiconductor channel lengths lead to a decrease in performance: some electrons (or holes) are able to flow between the electrodes even when they should not, causing heat and efficiency reduction. To overcome this performance degradation, transistor channels have to be made with nanometer-scale thin materials. However, even thin 3D materials are not good enough, as unpaired electrons, part of the so-called "dangling bonds" at the surface interfere with the flowing electrons, leading to scattering. FETs, so-called because an electrical signal sent through one electrode creates an electrical current throughout the device, are one of the pillars of the electronics industry, ubiquitous to computers, cell phones, tablets, pads and virtually every other widely used electronic device. All FETs are comprised of gate, source and drain electrodes connected by a channel through which a charge-carrier – either electrons or holes – flow. Mismatches between the crystal structure and atomic lattices of these individual components result in rough surfaces – often with dangling chemical bonds – that degrade charge-carrier mobility, especially at high electrical fields. Passing from thin 3D FETs to 2D FETs can overcome these problems and bring in new attractive properties. "FETs made from 2D semiconductors are free from short-channel effects because all electrons are confined in naturally atomically thin channels, free of dangling bonds at the surface," explains Ji Ho Sung, first author of the study. Moreover, single- and few-layer form of layered 2D materials have a wide range of electrical and tunable optical properties, atomic-scale thickness, mechanical flexibility and large bandgaps (1~2 eV).    Researchers produced the first 2D field-effect transistor (FET) made of a single materialThe major issue for 2D FET transistors is the existence of a large contact resistance at the interface between the 2D semiconductor and any bulk metal. To address this, the team devised a new technique to produce 2D transistors with semiconductor and metal made of the same chemical compound, molybdenum telluride (MoTe2). It is a polymorphic material, meaning that it can be used both as metal and as semiconductor. Contact resistance at the interface between the semiconductor and metallic MoTe2 is shown to be very low. Barrier height was lowered by a factor of 7, from 150meV to 22meV. IBS scientists used the chemical vapor deposition (CVD) technique to build high quality metallic or semiconducting MoTe2 crystals. The polymorphism is controlled by the temperature inside a hot-walled quartz-tube furnace filled with NaCl vapor: 710°C to obtain metal and 670°C for a semiconductor. The scientists also manufactured larger scale structures using stripes of tungsten diselenide (WSe2) alternated with tungsten ditelluride (WTe2). They first created a thin layer of semiconducting WSe2 with chemical vapor deposition, then scraped out some stripes and grew metallic WTe2 on its place. It is anticipated that in the future, it would be possible to realize an even smaller contact resistance, reaching the theoretical quantum limit, which is regarded as a major issue in the study of 2D materials, including graphene and other transition metal dichalcogenide materials. Ref.FDMT800120DCSTP160N3LL
