Self Assembled DNA-based Nanowires Conduct Electricity

Physicists recently conducted a current through gold-plated nanowires, which independently assembled themselves from single DNA strands. This important advance was made by scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and Paderborn University. The electronics industry has shrunk the size of transistors, central elements of computer chips, to fourteen nanometers in the last sixty years. But conventional…Continue readingSelf Assembled DNA-based Nanowires Conduct Electricity

Super-wrinkled Graphene Improves Battery Electrode Performance

A new method for making ultrathin metal-oxide sheets containing intricate wrinkle and crumple patterns has been found by researchers at Brown University. The textured metal-oxide films have better performance when used as photocatalysts and as battery electrodes, the researchers show in the journal ACS Nano. The findings extend previous work done by the same research…Continue readingSuper-wrinkled Graphene Improves Battery Electrode Performance

Metamaterials Enable Semiconductor-free Microelectronic Device

The first ever semiconductor-free, optically-controlled microelectronic device has been developed by engineers at the University of California San Diego. The team used metamaterials to build a microscale device that has a 1,000 percent increase in conductivity when activated by low voltage and a low power laser. The breakthrough basically amounts to a modern-day vacuum tube…Continue readingMetamaterials Enable Semiconductor-free Microelectronic Device

First Nanoscale Tunable Infrared Source Unveiled

A new nanoparticle amplifier that can generate infrared light and boost the output of one light by capturing and converting energy from a second light has been demonstrated by photonics researchers at Rice University. The creation of Rice’s Laboratory for Nanophotonics (LANP), the device functions similar to a laser. While lasers have a fixed output…Continue readingFirst Nanoscale Tunable Infrared Source Unveiled

Nanoscale Transducer Engine Is Powered By Light

A new nanoscale transducer, created by researchers at the University of Cambridge, is the world’s tiniest engine at just a few billionths of a metre in size. The engine, which uses light to power itself, could be the basis of future nano-machines that can navigate in water, sense the environment around them, or even enter…Continue readingNanoscale Transducer Engine Is Powered By Light

New Dust Fighting Tool Inspired By Geckos

The electronics industry, art conservators, and aerospace engineers can face major problems caused by micrometric and sub-micrometric contaminant particles. Or, as most of us call it, dust. These nanoparticles can stop a cellphone from functioning or steal the vividness from a painting’s colors. Taking a cue from the forces of static cling and the physics…Continue readingNew Dust Fighting Tool Inspired By Geckos
