Researchers create a first frequency comb of time-bin entangled qubits

Discovery is a significant step toward multi-channel quantum communication and higher capacity quantum computers

28-Apr-2016

Quantum mechanics, with its counter-intuitive rules for describing the behavior of tiny particles like photons and atoms, holds great promise for profound advances in the security and speed of how we communicate and compute. Now an international team of researchers has built a chip that generates ...

Flipping a chemical switch helps perovskite solar cells beat the heat

27-Apr-2016

Thin films of crystalline materials called perovskites provide a promising new way of making inexpensive and efficient solar cells. Now, an international team of researchers has shown a way of flipping a chemical switch that converts one type of perovskite into another -- a type that has better ...

Engineers develop micro-sized, liquid-metal particles for heat-free soldering

27-Apr-2016

Martin Thuo likes to look for new, affordable and clean ways to put science and technology to work in the world. His lab is dedicated to an idea called frugal innovation: "How do you do very high-level science or engineering with very little?" said Thuo, an assistant professor of materials ...

Cleaning up hybrid battery electrodes improves capacity and lifespan

25-Apr-2016

Hybrid batteries that charge faster than conventional ones could have significantly better electrical capacity and long-term stability when prepared with a gentle-sounding way of making electrodes. Called ion soft-landing, the high-precision technique resulted in electrodes that could store a ...

New method enlists electricity for easier, cheaper, greener chemistry

22-Apr-2016

Scientists at The Scripps Research Institute (TSRI) have found a new and better way to achieve a chemical reaction that is used widely in the pharmaceutical as well as flavor and fragrance industries. Traditional methods of "allylic oxidation" typically employ toxic and/or expensive reagents such ...

Making electronics out of coal

21-Apr-2016

Jeffrey Grossman thinks we've been looking at coal all wrong. Instead of just setting it afire, thus ignoring the molecular complexity of this highly varied material, he says, we should be harnessing the real value of that diversity and complex chemistry. Coal could become the basis for solar ...

Chemistry consortium uses Titan supercomputer to understand actinides

21-Apr-2016

Radioactive materials have long been a part of American history--from the Manhattan Project to the development of nuclear power. The materials central to these innovations are actinides, or elements 89-103 on the periodic table that release large amounts of energy when atoms are split. That same ...
