Fe3Si films are deposited onto the Si(111) wafer using sputtering with parallel facing targets. Surface modification of film is conducted by a microwave plasma treatment under an Ar atmosphere at different powers 50, 100 and, 150 W. After treatment, crystallinity coated enhanced, in which orientation peaks, including (220), (222), (400), and (422) sharpened. The extinction rule suggests that B2...
for button mushrooms packaging, the packaging films with high permeability to oxygen and carbon dioxide are required. permeability of plastic films such as pvc lead to loss of weight (and thus economic value) and textural changes are undesirable for button mushroom. so packaging film of polyolefins (pd 941 and pd 961) can be used. also the new film, hydrophilic materials such as films made from...
In the present investigation, we compared reduction in attachment ability of southern green stinkbug Nezara viridula (Hemiptera: Pentatomidae) to glass induced by three different nanoparticle (kaolin, zeolite, and calcium carbonate) films. Using traction force experiments, behavioral scanning electron microscopy observations, analyzed insect linear speed on untreated treated with particle The n...
In this paper, manufacturing and evaluation of ethanol gas sensors based on thin films of nanostructure tin oxide have been investigated. SnO2 thin films were prepared by both thermal evaporation (type I) and sputtering (type II) methods and heat treated on silicon wafer substrates. Scanning electron microscope (SEM), atomic force microscope (AFM), X-ray diffraction (XRD) and energy dispersive ...
ZnO and Cu doped[1] (CZO) thin films were prepared by radio frequency sputtering. The structural and optical properties of thin films were investigated using X-ray diffraction (XRD), atomic force microscopy (AFM), optical spectrophotometer, and photoluminescence (PL) techniques. ZnO thin films showed crystalline and micro-stress defects in the crystal lattice. Annealing of CZO thin films increa...
Users often struggle to stay digitally secure. Despite a multitude of security advice, they find it challenging to identify threats and develop appropriate behaviors to prevent potential attacks, especially in complex domains such as software updating. Our work seeks to improve the efficacy of security advice by exploring a new approach: video entertainment education (e.g. edutainment). Prior w...
A nominally room temperature photochemical method, simply employing ultraviolet light(187-254 nm) generated ozone environment, is shown to provide an efficient alternative for the removal of surfactant templates for a routine production of mesoporous silica thin films at low temperatures. The treatment concomitantly strengthens the silicate phase by fostering the condensation of unreacted silan...
The handling, dispersion, manipulation, and functionalization of carbon nanotubes and nanopipes often require the use of solvents. Therefore, a good understanding of the wetting properties of the carbon nanotubes is needed. Such knowledge is also essential for the design of nanotube-based nanofluidic devices, which hold the promise of revolutionizing chemical analysis, separation, drug delivery...
Novel nonafluorenes with a varying extent of pendant chirality were synthesized for an investigation of the origins of chiroptical activities in neat films. Thermal annealing of 4-microm-thick sandwiched films and of 90-nm-thick spin-cast films, all on surface-treated substrates, produced monodomain glassy films characterized as a right-handed cholesteric stack with a helical pitch length rangi...
We report the morphology and phase behaviors of blend thin films containing two polystyrene-b-poly(methyl methacrylate) (PS-b-PMMA) diblock copolymers with different blending compositions induced by a selective solvent for the PMMA block, which were studied by transmission electron microscopy (TEM). The neat asymmetric PS-b-PMMA diblock copolymers employed in this study, respectively coded as a...
