| First single-molecule LED created Posted: 03 Feb 2014 06:35 AM PST The ultimate challenge in the race to miniaturize light emitting diodes (LED) has now been met: Scientists have developed the first ever single-molecule LED. The device is formed from a single polythiophene wire placed between the tip of a scanning tunneling microscope and a gold surface. It emits light only when the current passes in a certain direction.  |
| Chemical products on a renewable basis Posted: 03 Feb 2014 05:40 AM PST A breakthrough in the use of renewable raw materials in chemical production has been achieved -- production of 5-(hydroxymethyl)furfural. Scientists have developed an innovative hydrothermal method to obtain the organic compound from biomass. Being a platform chemical, 5-HMF can serve as a precursor for various materials.  |
| Quantum dots provide complete control of photons Posted: 31 Jan 2014 07:12 AM PST By emitting photons from a quantum dot at the top of a micropyramid, researchers are creating a polarized light source for such things as energy-saving computer screens and wiretap-proof communications.  |
| New method measures mercury vapor for the first time Posted: 31 Jan 2014 05:34 AM PST An investigation to find out how much mercury energy-saving lamps contain has been conducted. Seventy-five commercially available lamps were tested, with encouraging results -- as far as mercury content goes they all contain less than the maximum allowed by law.  |
| New study finds differences in concussion risk between football helmets Posted: 30 Jan 2014 06:08 PM PST Football helmets can be designed to reduce the risk of concussions, according to a new study by some of the nation's leading concussion researchers.  |
| New instrument to study complex molecules invented Posted: 30 Jan 2014 01:43 PM PST An important new scientific instrument has been invented that allows scientists to study complex molecules. This is the world's first fully automated dual-frequency two-dimensional infrared spectrometer.  |
| Perceived benefits of casual video games among adults Posted: 30 Jan 2014 12:28 PM PST New research finds that while a majority of adults cite the ability to compete with friends as their primary reason for playing online casual video games such as Bejeweled Blitz, they report differing perceived benefits from playing the games based upon their age.  |
