Using a pair of exotic techniques including a molecular-scale version of ice fishing, a team of researchers working at the National Institute of Standards and Technology have developed methods to measure accurately the length of nanopores, the miniscule channels found in cell membranes.
Researchers at the National Institute of Standards and Technology and the Georgia Institute of Technology have demonstrated that atomic scale moire patterns, an interference pattern that appears when two or more grids are overlaid slightly askew, can be used to measure how sheets of graphene are stacked and reveal areas of strain.
But it's not all that computing power that's driving three Iowa State University and Ames Laboratory researchers as they develop computational chemistry at the petascale. Driving their project is the ability to run complex calculations and do better science.
Viele Zellen sind zu aktiver Bewegung faehig. Sie benutzen dazu einen inneren Antrieb mit Recycling-Funktion. Forschern gelang es mittels Kryo-Elektronentomographie, den Vorgang buchstaeblich einzufrieren und den molekularen Motor wirklichkeitsgetreu darzustellen.
A team of scientists working at beamline 9.0.1 of the Advanced Light Source (ALS) at the Lawrence Berkeley National Laboratory has used x-ray diffraction microscopy to make images of whole yeast cells, achieving the highest resolution - 11 to 13 nanometers - ever obtained with this method for biological specimens.
Lower CO2 emissions demand more renewable energy in the energy system. This calls for new solutions that take account of the considerable variations in the amount of wind energy, hydropower, solar energy etc. One of the solutions is a distributed energy system. Here it must be possible to store surplus energy locally using, for example, local SPEC electrolytic cells. The foundation for this technology is being developed by the CASE research project.
Scientists are combining the 3-D capability of MRI with the precision of a technique called atomic force microscopy. This combination enables 3-D visualization of tiny specimens such as viruses, cells and potentially structures inside cells - a 100-million-fold improvement over MRI used in hospitals.
Berkeley Lab scientists have established a revolutionary nanocrystal-making robot, capable of producing nanocrystals with staggering precision. This one-of-a-kind robot provides colloidal nanocrystals with custom-made properties for electronics, biological labeling and luminescent devices.
Tiny, melanin-covered nanoparticles may protect bone marrow from the harmful effects of radiation therapy, according to scientists at Albert Einstein College of Medicine of Yeshiva University who successfully tested the strategy in mouse models.
Nanotechnologists from the MESA+ research institute of the University of Twente have discovered that the photosynthesis system of bacteria can be used to transport light over relatively long distances.
Rice University researchers and their colleagues in Finland and Hungary have found a way to make carbon nanotube membranes that could find wide application as extra-fine air filters and as scaffolds for catalysts that speed chemical reactions.
The technology consortium Extreme Ultraviolet Lithography System Development Association (EUVA), today announced that its extreme ultraviolet (EUV) light source has achieved a power output of 104 Watts at the intermediate focus, at which EUV is effectively radiated.
