Electrospun polymer fibres better than non-woven polymer fibres at mopping up oil from oil spills
22-02-2013
Electrospun polystyrene shell/polyurethane core fibres made by scientists in China have absorption capacities 2-3 times higher than reported for non-woven polypropylene fibres (widely used to clean up oil spills). Electrospun fibres are an ideal candidate for soaking up oil, as their ...
Low-carbon hybrid energy systems -- China's future energy solutions
12-02-2013
A low-carbon solution to high-carbon energy resources such as coal is proposed by their high efficient integration with either nuclear or renewable energy, which may figure out the strategic solution to China's future energy development. Coal dominated energy resource and consumption ...
Materials: The first graphene-based chiral sensor
03-08-2011
A reusable, natural and cheap amylose-functionalised graphene sensor was developed for highly sensitive and visual fluorescent chiral sensing by a team in China.The team found that the sensor’s detection sensitivity toward L-tryptophan was over 100 times higher than that of recently reported ...
Hard or soft: at the touch of a button New nano material switches properties as required
08-06-2011
A world premiere: a material which changes its strength, virtually at the touch of a button. This transformation can be achieved in a matter of seconds through changes in the electron structure of a material; thus hard and brittle matter, for example, can become soft and malleable. What makes ...
New X-ray technique distinguishes between that which previously looked the same
A new method forms the basis for the widespread use of an X-ray technique which distinguishing types of tissue that normally appear the same in conventional X-ray images
27-07-2010
Traditional X-ray images can clearly distinguish between bones and soft tissue, with muscles, cartilage, tendons and soft-tissue tumours all look virtually identical. The phase-contrast technique developed a few years ago at the Paul Scherrer Institute enables X-ray images to be produced that ...
Researchers show applied electric field can significantly improve hydrogen storage properties
05-02-2010
An international team of researchers has identified a new theoretical approach that may one day make the synthesis of hydrogen fuel storage materials less complicated and improve the thermodynamics and reversibility of the system. Many researchers have their sights set on hydrogen as an ...
New visible light photocatalyst kills bacteria, even after light turned off
22-01-2010
In the battle against bacteria, researchers at the University of Illinois have developed a powerful new weapon – an enhanced photocatalytic disinfection process that uses visible light to destroy harmful bacteria and viruses, even in the dark. Based upon a new catalyst, the disinfection ...
Researchers design new graphene-based, nano-material with magnetic properties
A possible pathway to simply synthesize ferromagnetic graphene
04-09-2009
An international team of researchers has designed a new graphite-based, magnetic nano-material that acts as a semiconductor and could help material scientists create the next generation of electronic devices like microchips. The team of researchers from Virginia Commonwealth University; ...
New material for nanoscale computer chips
19-08-2009
Nanochemists from the Chinese Academy of Sciences and Nano-Science Center, Department of Chemistry at University of Copenhagen have developed nanoscale electric contacts out of organic and inorganic nanowires. In the contact they have crossed the wires like Mikado sticks and coupled several ...
Photoelectric switch
08-04-2009
A collaboration of scientists from various Beijing institutes, have made a pH-switchable, DNA-quantum dot hybrid that can also generate a photocurrent depending on the pH, allowing DNA to change conformation from a quadruplex to a double strand. Zhiyong Tang, Dongsheng Liu and colleagues ...
