Abstract

Electronic and spin properties of chiral platinum nanotubes are calculated using the relativistic linear augmented cylindrical waves method. The spin-orbit coupling induces the strong splitting of nonrelativistic dispersion curves for the Fermi energy region. The large differences in spin densities of states for spins up and down can be used to create pure spin currents through the tubules. In the two series Pt (5, n2) and Pt (10, n2), the (5, 3) and (10, 7) nanotubes show the strongest chiralit...

Abstract

The production of biodiesel attracts attention from scientists and researchers as of its tremendous applications and commercial use. It becomes important as of its eco-friendly nature, too, as it is biodegradable and non-polluting. The advantages of using petro-diesel with biodiesel lie in diminishing air pollution, encouraging the domestic supply of fuel, and creating new opportunities in agriculture. The production of biodiesel provides an alternative for agriculture as well as the industry. F...

Abstract

We have designed an absorber with ultra-broadband absorption spanning from visible light to near-infrared light. The performance of the designed absorber was validated with numerical analysis using the COMSOL simulation software. The absorber structure consists of two layers of square cubes stacked on top of four layers of continuous flat films. Starting from the top, the structure consists of an aluminum oxide (Al2O3) and titanium (Ti) cube, followed by a four-layer continuous planar film consi...

Abstract

With the rapid advancement of energy-saving light emitting diode (LED) lamps, LEDs have replaced traditional light sources with filaments known for their high energy consumption. LEDs also allow the persistent issue of providing a continuous and stable power supply for bicycles to be resolved. We delved into the characteristics of six commonly used materials for crafting car lamp housings and explored the advantages and disadvantages of the use of the materials in the production of car lamp hous...
