Scientists directly write flexible circuits with high-conductivity graphene inks

Scientists directly write flexible circuits with high-conductivity graphene inks Unlike metal wiring, which you can melt and deposit, graphene doesn’t really melt.They’ve come up with a way to print soft circuits using graphene ink — and the method keeps the graphene flakes in the same plane, making the printed graphene traces much more effective.

Could modern, nanoscale vacuum tubes replace transistors?

Researchers at the California Institute of Technology think they may have a solution to this problem — one that involves returning to a very old technology to solve the problems of existing methods.Axel Scherer, could be key to improving transistor performance and lowering power consumption.

New carbon nanotube breakthrough moves them one step closer to mass production

New carbon nanotube breakthrough moves them one step closer to mass production One of the critical problems facing carbon nanotubes is the difficulty of putting them precisely where they’re needed.46 G0, which is seven times higher than previous state-of-the-art CNT array FETs made by other methods.

New copper catalyst could close the carbon cycle, making ethanol from atmospheric CO2

New copper catalyst could close the carbon cycle, making ethanol from atmospheric CO2 In a quest to find a way to convert carbon dioxide into something useful, researchers from Oak Ridge National Labs in TN stumbled across an inexpensive, room-temperature catalyst for turning CO2 into ethanol.The new catalyst is made of copper nanoparticles, electroplated onto a substrate of vapor-deposited, nitrogen-doped graphene nanospikes, all atop a slice of n-type silicon semiconductor.

Explosions used to make large quantities of graphene

Explosions used to make large quantities of graphene The problem is that graphene is incredibly difficult to make, but researchers at Kansas State University (KSU) might have stumbled upon a solution.The KSU team was working on creating carbon soot aerosol gels with combustion.

Graphene-coated copper could dramatically boost future CPU performance

Graphene-coated copper could dramatically boost future CPU performance Every modern CPU is wired together via an extensive network of copper wires, dubbed “interconnects.” These tiny copper wires carry data across the processor and throughout the entire SoC.

Scientists finally make 'triangulene,' which is good, we think

Scientists finally make 'triangulene,' which is good, we think On paper, triangulene is made of six benzene rings, put together edge-on to make a flat triangular flake of a molecule that has a seemingly innocuous set of unpaired electrons.The icing on the proverbial cake is that the scientists who made triangulene have no idea how to handle it nor what to do with it.

Researchers put graphene to work manufacturing optoelectronics

Researchers put graphene to work manufacturing optoelectronics The researchers used an advanced light-based procedure to facilitate the creation of three-dimensional structures that comprise the resulting chip.Optoelectronics refers to devices that can emit, detect, and control light, and this kind of technology has applications in fields including renewable energy and security, according to the researchers.
