High Resolution Image Download MS PowerPoint Slide An essential component of mammalian cells, cholesterol exerts significant influence on the physical properties of the cell membrane and in turn its constituents, including membrane proteins. Although sparse, polar amino acid residues are highly conserved in membrane p…
Interest in using vegetable oils as dielectric coolants in power transformers dates back to the early studies on linseed- and castor- based fluids as possible replacements of mineral oil. However, interest in vegetable oils was lost due to their high viscosity and their tendency to oxidize. But, in the early 1990s and…
A strong effect of divertor configuration on the threshold power for the L-H transition (PLH) was observed in recent JET experiments in the new ITER-like Wall (ILW) [1], [2], [3]. Following a series of EDGE2D-EIRENE code simulations with Be impurity and drifts a possible mechanism for the PLH variation with the divert…
Eight cellulose degrading bacteria were isolated from compost and were identified as Bacillus licheniformis by 16S rRNA sequencing. Among the eight isolates, Bacillus licheniformis B4, B7 and B8 showed the highest cellulase activity. B. licheniformis B4 and B8 showed the maximum cellulase activity during the stationar…
Carrier mobility is a key parameter for the application of conjugated polymers. In this work, a series of polyfluorenes (PF2/6) with different fractions of crosslinkable acrylate groups is investigated. Mobility measurements are carried out to assess the influence of crosslinking with different photoinitiators on the…
BACKGROUND: The hypoalgesic effect of electromagnetic millimeter waves (MW) is well studied in animal model; however, the results of human research are controversial. The aim of this study was to evaluate the effects of various frequency ranges of MW on hypoalgesia using the cold pressor test (CPT). METHODS: Experimen…
In this paper, we report on a pressure sensor based on graphene aerogel functionalized with SnO 2 or GaN thin films deposited by magnetron sputtering. Decoration by nanocrystalline SnO 2 or GaN was found to enhance the piezoresistive response of the bare aerogel. The responsivity and pressure sensing range (from 1–5 a…
Studies of heavy metals adsorption in soil play a key role in predicting environmental susceptibility to contamination by toxic elements. The objective of this study was to evaluate cadmium (Cd) and copper (Cu) adsorption in surface and subsurface soil. Samples of six soils: Xanthic Hapludox (XH1 and XH2), Typic Haplu…
Abstract TRU resin can be used to rapidly and selectively extract Tc(VII) and Re(VII). The retention capacity curves of Tc(VII) and Re(VII) for HNO3, HCl, H2SO4 and H3PO4 solutions were studied and prepared. Tc(VII) and Re(VII) were simultaneously extracted in 2 M H2SO4 and 1.5 M H3PO4 and were effectively separated f…
The simulation of typical air-gap discharge process is of great significance to the long air-gap discharge mechanism and UHV transmission project design. A positive fractal dynamic streamer discharge model of a rod-plane air gap was established. On the basis of the original fractal streamer model, this new model propo…
Abstract A new technology for obtaining nanostructure on silicon surface for potential applications to optical devices is represented. Scanning electron microscope analysis indicated a grown nanostructure of dense forest consisting of long cylindrical needle cones with a length of approximately 300 nm and a mutual dis…
In order to provide a novel biomimetic composite substrate for tissue engineering and explore the interaction between cells and this type of material, we developed chitosan/liquid crystal (CS/LC) composite hydrogel with embedded LC phases by composing of cholesterol hydroxypropyl cellulose ester liquid crystalline mat…
Carbon nanostructural materials have gained the spotlight as promising anode materials for energy storage; they exhibit unique physico-chemical properties such as large surface area, short Li+ ion diffusion length, and high electrical conductivity, in addition to their long-term stability. However, carbon-nanostructur…
The paper recycling sector has undergone major changes in recent years, particularly regarding the quantity and quality of various materials processed. Material originating from board grades will increasingly dominate the recycling market as the use of printing papers decreases and the amount of non-fiber elements inc…
Bu-NENA (N-butyl-N-nitratoethyl nitramine) base propellants have versatile qualities, such as, higher energy, reduced sensitivity, and enhanced mechanical properties. The evaporation of Bu-NENA, which takes place in the propellant grains in the course of time, can reduce the physical properties of the propellants, wea…
According to classical nucleation theory, nucleation from solution involves the formation of small atomic clusters. Most formulations of classical nucleation use continuum "droplet" approximations to describe the properties of these clusters. However, the discrete atomic nature of very small clusters may cause deviati…
Abstract Neutron absorbers, especially boron, exhibit a comparatively large neutron absorption cross section, in particular, with regard to thermal neutrons. In this study, four boron compounds, including boron carbide (B4C), boron nitride (BN), boron trioxide (B2O3), and boric acid (H3BO3) were considered for shieldi…
Effect of Fe on microstructure and mechanical properties of the primary AlSi7Mg0.3 alloy and the potential of Mn addition to counteract any adverse effects was investigated in the present work. The primary AlSi7Mg0.3 is a better alloy than its counterpart with twice as much Fe. β platelets grow twice as big when the F…
Six mixed-ligand Co(II) coordination polymers, {[Co(adi)(iso-nia) 2 ]·dmf} n ( 1 ), [Co(adi)(iso-nia) 2 ] n ( 2 ), {[Co 2 (suc)(ac) 2 (iso-nia) 4 ][Co 2 (suc)(sucH) 2 (iso-nia) 4 ]·2dmf} n ( 3 ), [Co(adi)(nia) 2 ] n ( 4 ), {[Co(bdc)(nia) 2 ]·dmf} n ( 5 ), and {[Co(mal)(S-nia)(H 2 O)]·dmf} n ( 6 ), were synthesized and…
The in situ transmission electron microscopy technique is receiving considerable attention in material science research, as its in situ nature makes possible discoveries that ex situ instruments are unable to make and provides the capability of directly observing nanocrystal growth processes. As incresing amounts of d…
