the effects of nano titanium dioxide incorporation were investigated on the water vapor permeability, oxygen permeability, and antimicrobial properties of bovine gelatin films. the nano tio2 (tio2- n) was homogenized by sonication and incorporated into bovine gelatin solutions at different concentrations (e.g. 1, 2, 3, and 5% w/w of dried gelatin). the permeability of the films to water vapor a...

Nano-fibrillated cellulose was produced from flax and wheat straw cellulose pulps by high pressure disintegration. The reinforcing potential of both disintegrated nano-celluloses in a polyvinyl-alcohol matrix was evaluated. Disintegration of wheat straw was significantly more time and energy consuming. Disintegration did not lead to distinct changes in the degree of polymerization; however, the...

By introduction of nano-structured crystallite capping layers, the power conversion efficiency of top-illumination organic solar cells is improved from 4.2 ± 0.1% to 6.0 ± 0.2%, representing a 44% enhancement. This is caused by the increase in JSC and led by the enhancement in the local E distribution inside the active layers. Comprehensive finite-difference time domain simulation reveals two m...

The vapor deposition of open-networked carbon nanostructures and carbon nanotubes (CNTs)-reinforced composites have been developed and studied parametrically. Carbon nanostructures, including nano-tubes, nano-foams, nanoparticles, and nano-walls, have been deposited on catalyst-assisted substrates using microwave plasma electron cyclotron resonance-chemical vapor deposition (ECR-CVD) system at ...

Due to the economic importance of longevity of cut flowers, this study was conducted to evaluate the effect of nano-silver, silver thiosulfate, hydroxyl quinoline and a natural compound, thymol, on vase life and number of bacteria in cut stem ends of Rose flowers cv. Dolce vita. Cut flowers were transferred to laboratory at 22 ± 1ºC temperature and 60 ± 5% relative humidity. Cut flowers were ...

Abstract This study investigated the separation of bovine serum albumin using a novel matrix mixed membrane composed poly vinyl pyrrolidone and (phenylene ether sulfone)/Nano-silver. The responsive bare modified PEES/Nano-silver membranes were evaluated morphology, wettability, XRD ATR-FTIR. molecular weight cut-off (MWCO), water content, mean pore radius, porosity, pure flux used to evaluate p...

As a tribute to the scientific work of Professor Gareth Thomas in the field of structure-property relationships this paper delineates a new possibility of Lorentz transmission electron microscopy (LTEM) to study the magnetic properties of soft magnetic films. We show that in contrast to the traditional point of view, not only does the direction of the magnetization vector in nano-crystalline fi...
