All in one against CO2

Elemental Boron is an effective photothermocatalyst for the conversion of carbon dioxide

13-Apr-2017

A "self-heating" boron catalyst that makes particularly efficient use of sunlight to reduce carbon dioxide (CO2) serves as a light harvester, photothermal converter, hydrogen generator, and catalyst in one. Researchers introduce a photothermocatalytic reaction that requires no additives beyond ...

The "great smoky dragon" of Quantum Physics

Physicists evaluated the quantum delayed-choice experiments for the first time

15-Mar-2016

Physicists around Anton Zeilinger have, for the first time, evaluated the almost 100-year long history of quantum delayed-choice experiments – from the theoretical beginnings with Albert Einstein to the latest research works in the present. Since the 17th century, science was intrigued by the ...

An inexpensive rival to graphene aerogels

08-Jun-2015

The electromagnetic radiation discharged by electronic equipment and devices is known to hinder their smooth operation. Conventional materials used today to shield from incoming electromagnetic waves tend to be sheets of metal or composites, which rely on reflection as a shielding mechanism.But ...

Twist sound with metamaterials

27-Feb-2014

A Chinese-U.S. research team is exploring the use of metamaterials -- artificial materials engineered to have exotic properties not found in nature -- to create devices that manipulate sound in versatile and unprecedented ways. In the journal Applied Physics Letters, the team reports a simple ...

Brain process takes paper shape

14-Feb-2014

A paper-based device that mimics the electrochemical signalling in the human brain has been created by a group of researchers from China. The thin-film transistor (TFT) has been designed to replicate the junction between two neurons, known as a biological synapse, and could become a key component ...

Could zeolites make cigarettes safer to smoke?

03-Apr-2013

A self-protecting zeolite catalyst that degrades the carcinogens in cigarette smoke has been reported by scientists. The zeolite – which is prepared in a one-step hydrothermal crystallisation without any post treatment or shape direction – selectively breaks down tobacco specific nitrosamines ...

Artificial tongue made from polymer gel

15-Feb-2013

Scientists in China have made polymer gels that behave like artificial tongues. By measuring how the gels swell, bend and fluorescence, the researchers found that the gels selectively respond to and can distinguish between sourness (citric acid and gluconic acid), sweetness (glucose), saltiness ...

Changing the Channel in Nanoelectronics

New computer simulations may help in the design of efficient molecular wires

21-Apr-2010

Two types of trends can be identified in the length-dependent conductance of molecular wires, according to Chinese scientists. In an article published in ChemPhysChem, Jianwei Zhao and colleagues describe different length–conductivity relationships in molecular wires depending on the structures ...

Chemists create two-armed nanorobotic device to maneuver world's tiniest particles

18-Feb-2009

Chemists at New York University and China's Nanjing University have developed a two-armed nanorobotic device that can manipulate molecules within a device built from DNA. The device is described in Nature Nanotechnology . "The aim of nanotechnology is to put specific atomic and molecular ...
