... high pressure to matter significantly alters the interatomic
distances, and thus, the energy landscape by influencing
the nature of the intermolecular interactions, the chemical
bonding, the molecular configurations, the crystal structures
and the stability of materials. New classes of materials hav ...
Study on the Anode-to-Cathode Distance in an Aluminum Reduction
... long as the current eﬃciency (CE) is constant. The
electrical power loss from the bath resistance as a result
of the current increase can be reduced by decreasing the
anode-to-cathode distance (ACD). This is preferred to
make sure that the pots stay inside an operational
resistance load window where ...
Discoveries of New Topological STates of Matter Beyond Topological Insulators
... the topological Dirac semimetal phase in Cd3 As2 and Na3 Bi (featuring Fermi arc surface states), evidence for the topological Kondo insulator state in SmB6 , and the
demonstration of superconductivity and magnetism in the surface states of the prototypic TI Bi2 Se3 . Each of these new states exhibi ...
Titania-Silica Composites - Scientific Research Publishing
... Titania has several forms, but the two main crystal structures that most researchers focus on are rutile and anatase . These two crystal forms are both tetragonal structures in which titanium atoms are 6-coordinated in an
octahedral formation. The band gap of rutile is 3.0 eV and the band gap of ...

... efficient light emission. Meanwhile, although ZnSe and GaN as summarized
in Table 1 were known to be direct bandgap semiconductors, it was difficult
to grow large bulk crystals of these materials, and no p-type crystals had been
realized at that time. When it is difficult to produce large bulk cryst ...

... Also relevant in nucleation is the specific chemical interaction between nucleant substrate and
crystallising molecule, which may well dominate . In solution phase crystallisation, when both the
solute and solvent are polar, the polarisation effect governs the ability of solute molecule to adsor ...

... bandgap of 0.64 eV) enables the ability to easily control the width of the
bandgap by making compound with aluminium (Al) for larger one and
indium (In) for smaller one. This property makes it advantageous for
optoelectronics devices working in short wavelength range – such

Energy applications of nanotechnology
Over the past few decades, the fields of science and engineering have been seeking to develop new and improved types of energy technologies that have the capability of improving life all over the world. In order to make the next leap forward from the current generation of technology, scientists and engineers have been developing energy applications of nanotechnology. Nanotechnology, a new field in science, is any technology that contains components smaller than 100 nanometers. For scale, a single virus particle is about 100 nanometers in width.An important subfield of nanotechnology related to energy is nanofabrication. Nanofabrication is the process of designing and creating devices on the nanoscale. Creating devices smaller than 100 nanometers opens many doors for the development of new ways to capture, store, and transfer energy. The inherent level of control that nanofabrication could give scientists and engineers would be critical in providing the capability of solving many of the problems that the world is facing today related to the current generation of energy technologies.People in the fields of science and engineering have already begun developing ways of utilizing nanotechnology for the development of consumer products. Benefits already observed from the design of these products are an increased efficiency of lighting and heating, increased electrical storage capacity, and a decrease in the amount of pollution from the use of energy. Benefits such as these make the investment of capital in the research and development of nanotechnology a top priority.
