New plastics can conduct electricity !!!

Published on 2011-03-14 08:10:00

A newly discovered technique makes it possible to create a whole new array of plastics with metallic or even superconducting properties. Plastics usually conduct electricity so poorly that they are used to insulate electric cables but, by placing a thin film of metal onto a plastic sheet and mixing it into the polymer surface with an ion beam, Australian researchers have shown that the method can be used to make cheap, strong, flexible and conductive plastic films.The research has been p

New method for studying molecule reactions a breakthrough in organic chemistry

Published on 2011-03-14 08:07:00

Good chemists are passive-aggressive -- they manipulate molecules without actually touching them. In a feat of manipulating substances at the nanoscale, UCLA researchers and colleagues demonstrated a method for isolating two molecules together on a substrate and controlling how those two molecules react when excited with ultraviolet light, making detailed observations both before and after the reaction.Their research is published today in the journal Science."This is one step in mea

New phosphor for flat screen displays

The triangle and quadrangle show  the typical and enlarged colour range for FED phosphors, respectively Materials chemists in China have developed a compound that they believe should improve the quality of field emission displays (FEDs), bringing applications a step closer. FEDs have, for a number of years, been a promising technology for flat panel displays, but progress has been hampered by the display quality. Jun Lin at the Chinese Academy of Sciences, Changchun, and colleagues d

International Year of Chemistry launches across the world

Published on 2011-02-17 21:09:00

Over 1000 people from more than 60 countries helped to launch the International Year of Chemistry (IYC2011) at the United Nations Educational, Scientific and Cultural Organization (Unesco) headquarters in Paris, France, on 27-28 January.  The year-long celebration of all things chemistry has been assigned to 2011 by Unesco because this year marks the centenaries of both Marie Curie's Nobel prize in chemistry and the founding of the International Association of Chemical Soc

Adding floids to thicken up runny liquids

Published on 2011-02-17 21:06:00

The transition from weakly elastic, fluid-like behaviour to highly Adding a small amount of an immiscible fluid to a suspension - solid particles dispersed in a fluid - tunes the consistency of the suspension. The method could be used to create low-calorie foods, say the researchers in Germany. Controlling the flow or viscosity of suspensions is necessary to make various products including building materials, paints, and even food. Traditionally, surfactants or polymers are added whi

Standardising nanomaterials NOW!!

The repository will initially hold 25 types of industrially relevant materials like carbon nanotubes and various nanoparticles The European Commission's Joint Research Centre (JRC) has launched the world's first reference repository for nanomaterials, which will be used for safety assessment testing by national and international standardisation bodies. The repository, developed and administered by the JRC's Institute for Health and Consumer Protection in Ispra, Italy, is starting

a new class of magic atomic clusters called superhalogens discovered!

Published on 2011-02-14 00:58:00

  An international team of researchers has discovered a new class of magnetic superhalogens – a class of atomic clusters able to exhibit unusual stability at a specific size and composition, which may be used to advance materials science by allowing scientists to create a new class of salts with magnetic and super-oxidizing properties not previously found.The discovery, which was published Feb. 10 in the Early View issue of the international chemistry journal Angewandte Chemie Inter

First purely organic phosphor

Published on 2011-02-13 17:59:00

The organic phosphors being excited by UV light Scientists in the US have made a major advance in the development of novel light-emitting materials by designing the first purely organic phosphorescent compound. The finding could open the way for a new generation of materials for electronic displays and lighting, exploiting the relatively low cost and chemical versatility of systems based on organic molecules.  Currently, phosphorescence - the slow release of energy from a compound in

Now:Light Can Control Electrical Properties of Graphene

Published on 2011-01-16 06:48:00

New research published January 10, shows how light can be used to control the electrical properties of graphene, paving the way for graphene-based optoelectronic devices and highly sensitive sensors. This year's Nobel Prize for Physics was awarded for research into graphene, recognising its potential for many applications in modern life, from high-speed electronics to touchscreen technology. The UK's National Physical Laboratory, along with a team of international scientists, have further devel
