Scientists channel graphene to understand filtration and ion transport into cells

08.12. 2017 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms—ions—but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells. To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules, particularly water, that have an affinity for the charged atoms. But these molecular processes have traditionally been difficult to model—and therefore to understand—using computers or artificial structures.

Scientists watch diamond turn into graphite

08.12. 2017 Condensed Matter News - Physics News, Physic Materials News, Physics, Materials

In a surprising achievement, a team of scientists has turned diamond into graphite, using an X-ray laser. What may seem undesirable at first glance, is a decisive step forward in understanding the fundamental behaviour of solids when they absorb energetic radiation. For the first time, the researchers around Franz Tavella from SLAC National Accelerator Laboratory in the US, Sven Toleikis from DESY and Beata Ziaja from DESY and the Institute of Nuclear Physics in Krakow were able to follow the graphitization in a time-resolved manner. "In addition to these fundamental aspects, understanding the graphitization process is important for diamond-based technologies, since diamond is increasingly used for practical applications," the scientists write in the journal High Energy Density Physics.

During its 2017 Analyst Day at its Series 6 factory in Perrysburg, Ohio, First Solar Inc of Tempe, AZ, USA – which makes cadmium telluride (CdTe)-based thin-film photovoltaic modules as well as providing engineering, procurement & construction (EPC) services – said that, for full-year 2018, it is forecasting net sales of $2.3-2.5bn (down from 2017’s expected $3-3.1bn), with solar power systems comprising 75-80% of the total and third-party module sales the remainder. Shipments should amount to capacity of 2.7-2.8GW (up slightly from 2017’s expected 2.6-2.7GW)...

Spontaneous Bose-Einstein condensation of excitons

08.12. 2017 Quantum Physics News

Excitons are pairs of electrons and holes inside a solid material that together behave like a single particle. It has long been suspected that when many such excitons exist in the same piece of matter, they can form a single giant quantum state called a Bose-Einstein condensate – the same process which is responsible for a metal losing all its electrical resistance when it becomes a superconductor, for example. However, actually proving that Bose-Einstein condensation of excitons occurs in any real material has been a challenge for physicists for decades. An experiment done at the University of Illinois at Urbana-Champaign, carried out in collaboration with UvA-Institute of Physics researcher Jasper van Wezel, has uncovered evidence that this elusive state of matter really does exist. Their results were published in Science this week.
