Scientists have developed an ultra-thin coating material that has the potential to extend the life and improve the efficiency of lithium-sulfur batteries, one of the most promising areas of energy research today.
A group of researchers has shown that the simple curvature of nanomagnets can be used to induce textures within the magnetization field - a potential boon for future random access memory devices and data storage.
Chemists have created biosafe luminescent nanoparticles for imaging tumors and blood vessels damaged by heart attack or stroke. The particles are made of hafnium oxide that is allowed for intravenous injection, and doped with ions of rare earth metals.
Biophysicists have developed a strategy for using light-emitting nanocrystals as a marker in living cells. By recording the movements of these quantum dots, they can clarify the structure and dynamics of the cytoskeleton.
Researchers are currently developing the environment-friendly solar cells of the future, which will capture twice as much energy as the cells of today. The trick is to combine two different types of solar cells in order to utilize a much greater portion of the sunlight.
A recently launched research project aims to develop a biocomputer based on highly efficient molecular motors that will use a fraction of the energy of existing computers, and that can tackle problems where many solutions need to be explored simultaneously.
Researchers have produced special nanopowders, which are used as modifying additives in the production of aluminum alloys. This method will significantly improve the operational properties of the foundry products, and reduce the energy costs for its final processing.
In a new paper, scientists describe a material that, when heated to about 450 degrees Celsius, transforms from an atomically thin, two-dimensional sheet into an array of one-dimensional nanowires, each just a few atoms wide.
