Computing the electronic energy levels of a finite system or nanostructure is more difficult than computing those of an infinite system or bulk material. In the literature, a technique for simplifying this computation has been proposed, wherein energy levels of a finite system are derived from those of the correspondi…
Laminated wood-ceramics were created from beech veneer by impregnation with phenol formaldehyde resin and airtight sintering.The resulting laminated biocarbon material exhibited a clearly layered structure and partially preserved microstructural characteristics of normal wood.Laminated structure and airtight sintering…

Despite continued research efforts, poor aqueous solubility of active compounds remains a major problem in the design and formulation of medicines. Factors thought to contribute to the increasing number of poorly soluble new chemical entities (NCEs) include the increasing number of lipophilic drugs. These molecules, s…
Abstract The goal of the research presented here is to apply a global analysis of an inductively heated Czochralski furnace for a real sapphire crystal growth system and predict the characteristics of the temperature and flow fields in the system. To do it, for the beginning stage of a sapphire growth process, influen…
Abstract Bambusa dolichoclada Hayata (long-shoot bamboo) was liquefied in phenol with H2SO4 as a catalyst. The phenol-liquefied bamboo was then used as a raw material to prepare spherical phenol-formaldehyde (PF) resin beads by a suspension polymerization in a two-step process. The influence of the stirring speed (300…
We report a first-principles density-functional theory study of the origin of the magnetic properties of the quasi-one-dimensional spin systems ${\text{Sr}}_{2}{\text{V}}_{3}{\text{O}}_{9}$ and ${\text{Ba}}_{2}{\text{V}}_{3}{\text{O}}_{9}$. The calculated coupling constants are in very good agreement with experimental…
Abstract Epoxidized soybean oil (ESO) triglycerides were reacted with maleinized polybutadiene (MMPBD) to give plant‐oil‐based thermoset polymers. MMPBD samples were of two different molecular weights [high‐molecular‐weight maleinized polybutadiene (MMPBD‐H), maleate content = 10%, number‐average molecular weight (Mn)…
The role of complement C3 in mediating adhesion of monocytes to plasma deposited tetraglyme surfaces was studied. Although fibrinogen (Fg) is usually considered the main factor in mediating phagocyte attachment, plasma deposited PEO-like tetraethylene glycol dimethyl ether (tetraglyme) coatings that have ultra-low Fg…
We demonstrate photoelectron emission from millimeter-long forests of vertically aligned multiwalled carbon nanotubes using 266 nm light, which illuminates the forests from the side. We have measured quantum efficiencies in the order of ∼10−5 at low fields (pure photoemission) and ∼10−3 at an applied field of 0.3 V μm…
CdS is deposited on transparent conductive oxide (TCO)-coated glass substrate by radio frequency (r.f.) magnetron sputtering method. The X-ray diffraction (XRD) measurements revealed that CdS films were polycrystalline with the hexagonal wurtzite structure present only. The same conclusions as described below are arri…
p-type conduction in ZnO thin films has been realized by doping with GaN . Undoped and GaN -doped ZnO thin films were prepared by the pulsed laser deposition technique. All the grown films have been characterized by X-ray diffraction (XRD), atomic force microscopy (AFM) and Hall effect measurements in order to study t…
The propensity of a peptide chain for adopting helical secondary structure can be modulated not only through the solvation properties of its side chains but also through their size and shape. Here we examine a coarse-grained model for dendronized polypeptides that focuses on the susceptibility of α-helical structure t…
The characteristics of the MgO layer are known to be an important parameter that affects the discharge characteristics in an ac-PDP. In this paper, to improve the MgO characteristics of 50-in. full-HD ac-PDP with He (35%) – Xe (11%) contents, RF-plasma treatments on the MgO layer are examined under various gases for p…
Transmittance envelope of the thin film-substrate system and full spectra fitting method are two important methods to determine the optical constants of the optical thin films. Ion beam sputtering deposition technique was used to manufacture HfO2 single layer thin film onto fused silica substrate. The two methods were…
Cardiovascular heat shock protein (cvHsp) is an abundant and selectively expressed component in cardiac tissue with putative molecular functionality. The most prominent feature of cvHsp is the characteristic α-crystallin domain, which makes it a member of the small heat shock protein (sHsp) family. In the present stud…
Silicon nitride (SiNx) thin films were deposited by DC pulse reactive magnetron sputtering at ambient temperature. These films were characterized by spectroscopic ellipsometry(SE), X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES). It is found that among several regulable parameters, pulse f…
By using thermo-mechanical simulator,OM and TEM,the dynamic recrystallization (DRX) and precipitation behaviors of a kind of low carbon V-microalloyed steel have been investigated at temperatures ranging from 900 to 1050℃and strain rates from 0.01 to 10 s~(-1).The activation energy (Qdef) for hot deformation of this k…
Mg/B4C multilayer provides very high theoretical reflectivity in extreme ultraviolet range near 30.4nm wavelength, while the interface between Mg and B4C layer is very poor. In this paper, Co was introduced into the interface between Mg and B4C as a barrier layer. Mg/B4C and Co/Mg/Co/B4C multilayers were designed, fab…
Polycrystalline silicon (p-Si) is well-known as the high-efficency, low-cost, and most ideal material for manufacturing photovoltaic devices. In recent years, excimer-laser annealing (ELA), metal-induced crystallization (MIC) and solidphase crystallization (SPC) methods are employed to crystallize amorphous silicon (a…
