| New catalyst process uses light, not metal, for rapid polymerization Posted: 12 Jan 2015 03:13 PM PST A team of chemistry and materials science experts has created a novel way to overcome one of the major hurdles preventing the widespread use of controlled radical polymerization. |
| Solar cell polymers with multiplied electrical output Posted: 12 Jan 2015 10:39 AM PST Scientists paired up photovoltaic polymers that produce two units of electricity per unit of light instead of the usual one on a single molecular polymer chain. Having the two charges on the same molecule means the light-absorbing, energy-producing materials work efficiently when dissolved in liquids, which opens the way for a wide range of industrial scale manufacturing processes, including "printing" solar-energy-producing material like ink. |
| From the bottom up: Manipulating nanoribbons at the molecular level Posted: 12 Jan 2015 10:39 AM PST Researchers have developed a new precision approach for synthesizing graphene nanoribbons from pre-designed molecular building blocks. Using this process the researchers have built nanoribbons that have enhanced properties--such as position-dependent, tunable bandgaps--that are potentially very useful for next-generation electronic circuitry. |
