Researchers from NIST have established guidelines for using surface plasmon polaritons (SPPs) to improve absorption in both photovoltaic or photoelectrochemical cells used for energy conversion. In both types of photocells, SPPs have the potential to increase the amount of light absorbed in the active material layer, improving the overall efficiency of light collection in solar energy devices.
Scientists have developed a novel and versatile modeling strategy to simulate polyelectrolyte systems. The model has applications for creating new materials as well as for studying polyelectrolytes, including DNA and RNA.
Silvija Gradecak has big intentions for small ingredients. The associate professor of materials science and engineering focuses on energy conversion and light harvesting through the use of nanomaterials.
A disturbance in the local magnetic order of a solid body can propagate across a material just like a wave. This wave is named spin wave and its quanta are known as magnons. Physicists propose the usage of magnons to carry and process information instead of electrons as it is done in electronics.
Researchers have, successfully observed and touched the rotational motion of a 1-nm synthetic molecular machine through the application of a single-molecule capturing and manipulation technique using optical microscopy and a bead probe, which allows visualization of molecular mechanical motion.
Zwei elektrische Isolatoren aneinander bringen und dadurch einen elektrischen Supraleiter erzeugen: Wer solche Phänomene in Nanostrukturen analysieren will, stößt schnell an messtechnische Grenzen - es sei denn, er benutzt eine neue Methode, die Würzburger Physiker mitentwickelt haben.
A combination of three modes of therapy - photodynamic therapy, chemotherapy and radiotherapy - integrated into a single platform, it is hoped that this treatment would increase treatment efficacy and reduce side effects for cancer patients.
When sunbathers splash into the ocean to cool off, some of their lotions and creams get rinsed into the water. The problem is that titanium dioxide and zinc oxide nanoparticles, which are common ingredients in sunblock, can react with ultraviolet light from the sun and form new compounds, such as hydrogen peroxide, that could be toxic.
A simple and effective way of unravelling the often tangled mass of DNA is to 'thread' the strand into a nano-channel. A new study used simulations to measure the characteristics that this channel should have in order to achieve maximum efficiency.
For the first time, chemists have succeeded in measuring vibrational motion of a single molecule with a femtosecond time resolution. The study reveals how vibration of a single molecule differs from the behaviour of larger molecular groups.
David Erickson, professor of mechanical and aerospace engineering at Cornell University, will receive a $3 million National Science Foundation grant over five years to adapt smart phones for health monitoring.
