DNA origami could lead to nano 'transformers' for biomedical applications

Tiny hinges and pistons hint at possible complexity of future nano-robots

07-Jan-2015

If the new nano-machines built at The Ohio State University look familiar, it's because they were designed with full-size mechanical parts such as hinges and pistons in mind. The project is the first to prove that the same basic design principles that apply to typical full-size machine parts can ...

University of Tennessee professor researches rare rock with 30,000 diamonds

Researcher examined a rare rock using a giant X-ray machine to study the diamonds and their relationships with associated materials

07-Jan-2015

Diamonds are beautiful and enigmatic. Though chemical reactions that create the highly coveted sparkles still remain a mystery, a professor from the University of Tennessee, Knoxville, is studying a rare rock covered in diamonds that may hold clues to the gem's origins. The golf-ball sized chunk ...

Gift-wrapped gas molecules

Scientists in France and Scotland identify new encapsulation agents for delivery of nitric oxide, a potent antibacterial agent and vasodilator

06-Jan-2015

A group of scientists led by researchers at the Université de Versailles' Institut Lavoisier in France has worked out how to stably gift-wrap a chemical gas known as nitric oxide within metal-organic frameworks. Such an encapsulated chemical may allow doctors to administer nitric oxide in a more ...

A qubit candidate shines brighter

Precisely placing imperfections called 'nitrogen vacancy centers' within nano-sized diamond structures can boost their fluorescence

05-Jan-2015

In the race to design the world's first universal quantum computer, a special kind of diamond defect called a nitrogen vacancy (NV) center is playing a big role. NV centers consist of a nitrogen atom and a vacant site that together replace two adjacent carbon atoms in diamond crystal. The defects ...

Scientists measure speedy electrons in silicon

Attosecond laser provides first 'movie' of fast electrons jumping band-gap of semiconductor

22-Dec-2014

The entire semiconductor industry, not to mention Silicon Valley, is built on the propensity of electrons in silicon to get kicked out of their atomic shells and become free. These mobile electrons are routed and switched though transistors, carrying the digital information that characterizes our ...
