Photonic jet is a localized sub-wavelength beam generated at the shadow-side surfaces of microscale dielectric cylinders or spheres, when they are illuminated by an electromagnetic wave. We demonstrate the potential of the photonic jets for micro-etching using a nanosecond Near-IR laser (l=1064 nm) that...

Nanocrystalline cellulose has been successfully studied by conventional scanning electron microscopy (SEM, JSM-6510LA). Nanocrystalline cellulose was extracted from the natural fibers by the chemical treatments of alkalization and bleaching followed by acid hydrolysis. Alkalization and bleaching resulted...

We characterized the four main chain liquid crystal elastomers (MCLCEs) samples using the x-ray diffraction method. The four samples had different concentration of crosslinkers, i.e 8%, 12%, 14% and 16%. There was a relationship between crosslinkers concentration and d-spacing parameter here, namely...

We report the calculation of the Density of States (DOS) in Twisted Bilayer Graphene (TBG) system for low energy range near Fermi level using commensurate rotation of 1.160, 1.790 and 3.480. We obtain a logarithmic behaviour of DOS showing that van Hove Singularities (VHS) are occurred in this system...

Emission of terahertz (THz) radiation as a result of optical rectification of intense femtosecond laser pulses on chiral metamaterials has been observed. The chiral metamamaterials has simplified fabrication design but still capable to exhibit different refractive index for each circular polarization....
