The study of the mechanisms underlying formation of molten globule states in proteins is gaining growing interest due to recent discoveries concerning the involvement of this folding intermediate in several biological processes and to the possibility it offers to clarify the general process of protein folding. Differe…
Abstract Thiadiazole compounds including 3-hydroxy-4-substituted-1,2,5-thiadiazole are known as non-nucleoside inhibitors of HIV-1. Density functional calculations at the B3LYP/6-311++G(d,p) level were employed to determine the stability, tautomerism, and substituent effects of 1,2,5-thiadiazole, a widely used skin-wh…
Dedicated experiments in the HT-7 tokamak were performed to investigate the influence of erosion and deposition on the mirror samples. The first mirror (FM) samples made of polycrystalline (PC) stainless steel (SS), molybdenum (Mo) and tungsten (W) were fixed on a holder at an angle of 45° with respect to the horizont…
Controllable interfacial alloying is achieved at a Au-ZnSe nanowire (M-S) contact via in situ Joule heating inside transmission electron microscopy (TEM). TEM inspection reveals that the Au electrode is locally molten at the M-S contact and the tip of the ZnSe nanowire is covered by the Au melting. Experimental eviden…
Three types of montmorillonite (Mt) clay (one natural and two organo) with 4 wt% were used to modify bitumens with different penetration grades. X-ray diffraction (XRD) was employed to observe structures of Mt in bitumen. Rolling thin film oven testing (RTFOT) and pressure-aging vessel (PAV) methods were used to simul…
The complexes [Co(DioxH) 2 L 2 ][SbF 6 ] · n H 2 O, where DioxH is dimethylglyoxime monoanion (DioxH − ) or 1,2-cyclohexanedione dioxime (NioxH − ), L is aniline (An) or triphenylphosphine (PPh 3 ), were isolated from the CoX 2 · n H 2 O-NaSbF 6 -DioxH 2 -L system (X = F or CH 3 COO) in aqueous methanol. The complexes…
The advanced two-plate model with BET adsorption equation has been verified by the use of the experimental Cu 2+ /Cu 0 system in 1 M NaClO 4 /pH 3 solution at different scan rates and at 5, 10, 25 mM concentrations of Cu 2+ . A change of electrode properties during electrode process was included into the applied model…
Bamboo is mainly a tropical and subtropical plant which is found adequate in many countries. The strength of bamboo as concrete reinforcement is much lower than steel bar reinforcement. However, one of the merits is a cheap and replenishable agricultural resource and abundantly available. Due to excellent properties l…
We present nanophotonic structures consisting of a dielectric slab waveguide with low index contrast and photonic crystals. The guided-mode resonance effect is used to implement elements with selective reflection properties. The design procedure, including numerical simulations, as well as a fabrication approach emplo…
Abstract Y 2 O 3 dispersion strengthened iron‐based powders and oxide dispersion strengthened (ODS) alloys were prepared by hydrothermal synthesis and spark plasma sintering (SPS), respectively. The effects of Y 2 O 3 , vibratory milling treatment, and Ti element on the microstructure and mechanical properties of the…
Graphene film was fabricated using graphene oxide (GO) prepared from a modified Hummers' method. The reduction of GO (rGO) was accomplished by coating the GO paste on a piece of glass and immersing into a Ti+3solution. The freeze drying (FD) process employed for drying GO before its forming of paste and coating into a…
The use of a weakly binding ligand to facilitate sintering between particles and a planar substrate in the absence of pressure and at low homologous temperature has been explored. Ag nanoparticles in the 5-15 nm range suspended in water and stabilized by a BH4complex were dropped onto a polished Ag substrate heated to…
A thorough study of exposure parameters for electron beam lithography using AR7520 negative tone electron beam resist is here presented. We optimized the beam voltage, apertures diameter and resist thickness in order to achieve the smaller dimensions possible for each resist thicknesses. Monte Carlo simulations of the…
In view of the continued disputes on the fundamental question of whether the surface tension of a vapour bubble in liquid argon increases, or decreases, or remains unchanged with the increase of curvature radius, a cylindrical vapour bubble of argon is studied by molecular dynamics simulation in this paper instead of…
Few histologic and histomorphometric reports are present in the literature regarding the peri-implant bone response around implants inserted in sinuses grafted with different biomaterials. Anorganic bovine bone (ABB) and anorganic bovine matrix with the addition of an active cell-binding peptide (PepGen P-15) are xeno…
Carbonado, a variety of natural polycrystalline diamond whose origin remains unknown, differs notably in the properties from common diamonds of mantle origin. In this study, infrared spectroscopic and microscopic analyses were conducted on carbonado from the Central African Republic. Stepwise heating followed by infra…
Mono/dibenzyltoluene (M/DBT) is based on synthetic aromatic hydrocarbons. It is an insulating liquid with specifications meeting standard IEC 60867 where it is defined as methylpolyarylmethane derivatives. M/DBT has been used in high voltage capacitors for over 25 years. It has also been approved for other electrical…
The purpose of this work is to conduct the multi-physics simulation analysis of LED-based luminaires under certain temperature and humidity environment, and to find out the vulnerable spot of the luminaire. The coupled modeling of LED luminaire during step stress accelerated test (SSAT) is simulated by ANSYS. Five typ…
In this paper, we report a methodology to fabricate high resolution periodic grating features using high index prism based interferometer and i-line laser source. Features with sub-60 nm half pitch size were fabricated on i-line resist in an immersion medium using a prism of high index 1.939.
Abstract This paper reports on an investigation into fuel design choices of a pressurized water reactor operating in a self-sustainable Th-233U fuel cycle. In order to evaluate feasibility of this concept, two types of fuel assembly lattices were considered: square and hexagonal. The hexagonal lattice may offer some a…
