Hydrogen incorporation in silicon layers prepared by plasma-enhanced chemical-vapor deposition using silane dilution hydrogen has been studied infrared spectroscopy (IR) and elastic recoil detection analysis (ERDA). The large range of investigated can be divided into an amorphous a microcrystalline zone. These two zones are separated narrow transition zone at level 7.5%; here, the structure material cannot clearly identified. films in/near amorphous/microcrystalline show considerably...
Photodegradation and oxidation are major causes of the deterioration food, resulting in darkening, off-flavors, nutrient deficiency. To reduce this problem, novel functional polymeric materials being developed to retain food’s light sensitivity. Nanofillers also used a film produce effective UV blockings oxygen barrier coatings so that degradation food can be delayed, thereby increasing shelf life. For purpose, polyvinyl alcohol were prepared by incorporation ZnO nanoparticles. Polyvinyl is...

FTIR confirms material identification displaying some peaks fingerprint region. UV Vis yields high...
A series of samples was deposited by very high frequency glow discharge in a plasma silane diluted hydrogen concentrations SiH4/(SiH4+H2) varying from 100% to 1.25%. For below 8.4%, phase transition between amorphous and microcrystalline silicon occurs. Microcrystalline has been characterized transmission electron microscopy (TEM) x-ray diffraction. The medium-resolution TEM observations show that the transition, microstructure varies complex way, showing large variety different growth...
Most of the food packaging materials used in market are petroleum-based plastics; such neither biodegradable nor environmentally friendly and require years to decompose. To overcome these problems, edible encouraged be because degrade quickly due actions bacteria, fungi, other environmental effects. In this work, commonly available household as gelatin, soy protein, corn starch, papaya were prepare cost-effective lab-scale film an effective alternative commercial plastics reduce waste...
