Hyperbranched polymers have already been used to develop materials such as resins and wood coatings with improved durability and resistance to abrasion. These exploit the fact that molecules with multiple branches tend to cling together more strongly, making them resistant to wear. But hyperbranched polymers also have other properties, such as low viscosity, which makes them suitable for applications such as flexible electronic displays.
Some organic substances have a property called photochromism, meaning that their absorption spectrum, or color, changes when they are exposed to certain types of light. In particular, a new artificial protein called Dronpa shows great promise for applications because it can be switched back and forth between a 'bright' state and a 'dark' state.
Scientists at the RIKEN Advanced Science Institute, Wako, Saitama University, Saitama, and the National Institute of Advanced Industrial Science and Technology, Tsukuba, have demonstrated that an organic film can be switched from being a superconductor to an insulator through the proper choice of substrate.
The Ben Franklin Venture Investment Forum (BFVIF) in conjunction with the Ben Franklin Technology Partners of Central and Northern PA (BFTP) announces the Big Idea Business Plan Contest.The grand prize of $100,000 will be awarded to one technology-oriented company start or further develop the business in Pennsylvania.
The international chemical and pharmaceutical group Solvay today signs an agreement to become part of the research network of Holst Centre, an open-innovation initiative by IMEC (Belgium) and TNO (The Netherlands).
CSC today announced that a wave of disruptive technologies is reshaping industry, triggering new business models and altering consumer and employee behaviors, according to a report issued by CSC?s Leading Edge Forum (LEF).
How does one make and measure a qubit? The problem has engaged scientists for years. Many arrangements have been proposed and some demonstrated, each with its advantages and disadvantages, including tricky schemes involving superconducting tunnel junctions, quantum dots, neutral atoms in optical lattices, trapped ions probed by lasers, and so on.
University of New South Wales' (UNSW) ARC Photovoltaic Centre of Excellence has again asserted its leadership in solar cell technology by reporting the first silicon solar cell to achieve the milestone of 25 per cent effiency.
With a $1.6M grant from the U.S. Office of Naval Research, UC San Diego NanoEngineering professor Joseph Wang will lead a project to create a 'field hospital on a chip' that soldiers can wear on the battlefield.
A zinc oxide nanorod field-effect transistor (FET), the first of its kind as a nano device in China, was successfully fabricated by scientists with the Institute of Microelectronics, Chinese Academy of Sciences.
The Bio Meets Nano and IT conference in Oulu, Finland from December 9-11, 2008, brings together companies, organisations and research groups with the purpose of enhancing international and interdisciplinary business collaboration in the fields of life sciences, micro- and nanotechnology and information technology.
