Nanotubes and Nitro…

Topics: Carbon Nanotubes, Materials Science, Nanotechnology From TNT to nitro-glycerine, nitrogen-rich compounds are known for packing an explosive punch. When these materials explode, bonds between atoms in the compounds are broken, which gives a chance for two nitrogen atoms to form very strong triple bonds with each other. This releases an enormous amount of chemicalContinue reading “Nanotubes and Nitro…”

Quantum Charging…

Topics: Alternate Energy, Battery, Green Tech, Nanotechnology, Quantum Mechanics Note: I’m in the semifinals of the 3-Minute Thesis competition, so I decided to focus on my presentation. Wish me luck. This does, however, relate to our need as a species to get off fossil fuels as soon as possible, so things like Ukraine, Crimea, andContinue reading “Quantum Charging…”

Wearable Pressure Sensors…

Topics: Applied Physics, Biotechnology, Nanotechnology Wearable pressure sensors are commonly used in medicine to track vital signs, and in robotics to help mechanical fingers handle delicate objects. Conventional soft capacitive pressure sensors only work at pressures below 3 kPa, however, meaning that something as simple as tight-fitting clothing can hinder their performance. A team ofContinue reading “Wearable Pressure Sensors…”

Vortex Beams…

Topics: Bose-Einstein Condensate, Nanotechnology, Particle Physics, Quantum Optics A wave-like property previously only seen in beams of light and electrons has been observed for the first time in atoms and molecules. By passing beams of helium and neon through a grid of specially shaped nanoslits, researchers led by Edvardas Narevicius of Israel’s Weizmann Institute of Science succeededContinue reading “Vortex Beams…”

Big Bet on Small…

Topics: Futurism, Materials Science, Nanotechnology The National Nanotechnology Initiative promised a lot. It has delivered more. We’re now more than two decades out from the initial announcement of the National Nanotechnology Initiative (NNI), a federal program from President Bill Clinton founded in 2000 to support nanotechnology research and development in universities, government agencies, and industryContinue reading “Big Bet on Small…”

LCE…

Topics: Materials Science, Mechanical Engineering, Nanotechnology, Robotics A new artificial fiber spun from a polymer called liquid crystal elastomer (LCE) using high-voltage electricity replicates the strength, responsiveness, and power density of human muscle fibers, scientists report. When powered by heat or near-infrared light, the fibers pulled upward and downward or oscillated back and forth. “OurContinue reading “LCE…”

Exciton Surfing…

Topics: Alternate Energy, Applied Physics, Materials Science, Nanotechnology, Solar Power Organic solar cells (OSCs) are fascinating devices where layers of organic molecules or polymers carry out light absorption and subsequent transport of energy – the tasks that make a solar cell work. Until now, the efficiency of OSCs has been thought to be constrained byContinue reading “Exciton Surfing…”

Biggie’s Starship…

Topics: Materials Science, Nanotechnology, Space Exploration, Spaceflight, Star Trek China is investigating how to build ultra-large spacecraft that are up to 0.6 mile (1 kilometer) long. But how feasible is the idea, and what would be the use of such a massive spacecraft? The project is part of a wider call for research proposals fromContinue reading “Biggie’s Starship…”

Cooling Computer Chips…

Topics: Materials Science, Nanotechnology, Semiconductor Technology A novel semiconducting material with high thermal conductivity can be integrated into high-power computer chips to cool them down and so improve their performance. The material, boron arsenide, is better at removing heat than the best thermal-management devices available today, according to the US-based researchers who developed it. TheContinue reading “Cooling Computer Chips…”

Stop-Motion Efficiency…

Topics: Applied Physics, Electrical Engineering, Nanotechnology, Semiconductor Technology A new ultrafast imaging technique that captures the motion of atoms in nanoscale electronic devices has revealed the existence of a short-lived electronic state that could make it possible to develop faster and more energy-efficient computers. The imaging technique, which involves switching the devices on and offContinue reading “Stop-Motion Efficiency…”
