Simple urine test uses nanotechnology to detect dangerous blood clotting
Life-threatening blood clots can form in anyone who sits on a plane for a long time, is confined to bed while recovering from surgery, or takes certain medications.
First all-carbon solar cell
(Phys.org)—Stanford University scientists have built the first solar cell made entirely of carbon, a promising alternative to the expensive materials used in photovoltaic devices today.
Scientists build thinnest-possible LEDs to be stronger, more energy efficient
(Phys.org) —Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors ...
Weighing nanoparticles at the attogram scale
MIT engineers have devised a way to measure the mass of particles with a resolution better than an attogram—one millionth of a trillionth of a gram. Weighing these tiny particles, including both synthetic ...
Beyond the Moore's Law: Nanocomputing using nanowire tiles
An interdisciplinary team of scientists and engineers from The MITRE Corporation and Harvard University have taken key steps toward ultra-small electronic computer systems that push beyond the imminent end ...
Graphene balloon yields unprecedented images of hydrated protein molecules
(Phys.org) —A graphene water balloon may soon open up new vistas for scientists seeking to understand health and disease at the most fundamental level.
Microwave oven cooks up solar cell material
University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used ...
Nano-scientists develop new kind of portable water purification system
New solar cell technology captures high-energy photons more efficiently
(Phys.org) —Getting the blues is rarely a desirable experience—unless you're a solar cell, that is.
Nanotube-based sensors can be implanted under the skin for a year
Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed, ...
Another tiny miracle: Graphene oxide soaks up radioactive waste
(Phys.org)—Graphene oxide has a remarkable ability to quickly remove radioactive material from contaminated water, researchers at Rice University and Lomonosov Moscow State University have found.
