Researchers from the University of California, Irvine, have developed a nanowire-based battery material that has the potential to be recharged several times, bringing us closer to commercial batteries with a prolonged lifespan for spacecraft, cars, appliances, smartphones, and computers.
Scientists at the U.S. Naval Research Laboratory (NRL) have devised a clever combination of materials - when used during the thin-film growth process - to reveal that particle atomic layer deposition, or p-ALD, deposits a uniform nanometer-thick shell on core particles regardless of core size, a discovery having significant impacts for many applications since most large scale powder production techniques form powder batches that are made up of a range of particles sizes.
Jeffrey Grossman believes that for a very long time we have been observing coal from a totally wrong perspective. He stresses the necessity to explore the real value of the complex chemistry and diversity of the material, instead of just ignoring its molecular complexity and setting it afire. Grossman and his team of researchers highlighted the possibility of coal becoming the foundation for electronic devices, batteries, or solar panels.
Worldwide growing data volumes make conventional electronic processing reach its limits. Future information technology is therefore expected to use light as a medium for quick data transmission also within computer chips. Researchers under the direction of KIT have now demonstrated that carbon nanotubes are suited for use as on-chip light source for tomorrow’s information technology, when nanostructured waveguides are applied to obtain the desired light properties. The scientists now present their results in Nature Photonics. DOI: 10.1038/NPHOTON. 2016.70
Scientists from the United Kingdom and Germany have undertaken studies on magnetic nanovortices present in magnetite minerals. They reveal that these structures are reliable witnesses of the earth's history. The structures are constructed in the molten rock cooling process, and during their formation the magnetic structures reflect the magnetic field of the earth.
Radical new properties present in a nanomaterial have been discovered by physicists. This discovery provides the potential to develop greatly efficient thermophotovoltaic cells, which in the future will be able to harvest heat in the dark and then convert it into electricity.
Over the past two years, phosphorene has gained increased attention because of its potential in flexible, thin electronics. Phosphorene is naturally a semi-conductor, providing potential where the miracle material graphene falls short.
Growing crystalline film layers, also known as epitaxy, are templated using a crystalline substrate. Epitaxy is considered to be the foundation to develop semiconductors and transistors. If the material in onr deposited layer is the same as the material present in the next layer, it energetically helps the formation of firm bonds between perfectly matched, highly arranged layers. In comparison to this, it is extremely difficult to even attempt to layer dissimilar materials when the crystal lattices fail to easily match. In this case, weak van der Waals forces develop attraction but do not develop firm bonds between unlike layers.
MIPT scientists have successfully developed ultra-thin ferroelectric films that are 2.5-nanometres. These films were formed based on hafnium oxide that is capable of being used for developing non-volatile memory elements known as ferroelectric tunnel junctions. The results of this research features in ACS Appl. Mater. Interfaces.
A team of researchers, led by chemist Paul Cherukuri from Rice University, have stumbled upon a Tesla coil’s robust force field, which causes the self-assembly of carbon nanotubes into long wires. This unique phenomenon has been dubbed as “Teslaphoresis.” The research findings have been reported by in the ACS Nano journal. Cherukuri suggests that this research would be the foundation toward scalable assembly of nanotubes from scratch.
