Verbascoside or acteoside is the most abundant phenylethanoid glycoside that possesses health beneficial pharmacological activities, including anti-nociceptive, anti-inflammatory and anti-cancer. Due to the wide range of pharmacological activities of verbascoside and insufficient data on the safety profile, the acute,…
Abstract The aim of this paper is to study the influence of water on the mechanical properties of thermoplastic starch films. Experimental observations of Young modulus and the breaking force of thermoplastic starch foils with different percentages of polyvinyl alcohol and keratin additives and screw rotation speeds a…
PURPOSE: This study evaluated the effect of air abrasion and polishing regimens on the flexural strength of yttrium stabilized polycrystalline tetragonal zirconia (Y-TZP). METHODS: From Y-TZP blocks (InCeram 2000 YZ Cubes; Vita Zahnfabrik, Bad Säckingen, Germany) 120 bars (25 mm × 4 mm × 1.2 mm) were obtained accordin…
Cu doped SnO2nanoparticles were prepared using the chemical precipitation method. The Cu doped SnO2nanoparticles have been characterized by powder X-ray diffraction (XRD) analysis, Scanning electron microscopy (SEM), elemental dispersive X-ray (EDX) analysis, Transmission electron microscopy (TEM), UV-Visible absorpti…
This review systematizes and analyzes the physicochemical and catalytic properties of micro/mesoporous materials prepared by two-step recrystallization. The materials are divided into three groups according to the degree of recrystallization: (1) mesostructured zeolites (RZEO-1), (2) micro/mesoporous nanocomposites (R…
BACKGROUND: Small interfering RNA (siRNA)-mediated gene therapy is a promising strategy to temporarily inhibit the expression of genes involved in development of breast cancer. The lack of a safe and efficient gene delivery system has become a major hurdle for siRNA-mediated gene therapy in breast cancer. Our previous…
Integrated continuous manufacturing offers ample opportunities for efficient and cost-effective pharmaceutical processes. Plant-wide control is required for meeting the stringent regulatory requirements on quality attributes of products in continuous pharmaceutical manufacturing processes. This paper investigates plan…
Elucidation of the molecular-level mechanics underlying the dissolution of salts is one of the long-standing, fundamental problems in electrolyte chemistry. Here we follow the incremental structural changes that occur when water molecules are sequentially added to the ternary [MgSO4Mg](2+) ionic assembly using cryogen…
Over the years, great advances have been made in the field of auxetic metamaterials where one of the main focuses was the production of systems which can be produced through simple and relatively inexpensive means. In this work, auxetic systems created through the introduction of elliptical grooves, meant to mimic the…
In this paper a fast and templatable planning framework is proposed to solve the automatic spray trajectory generating problem on typical regular surfaces including planes, cylindrical surfaces, conical surfaces and spherical surfaces. The elliptical double-beta static coating growth rate model is selected as a refere…
Poly(3,4-ethylenedioxythiophene) (PEDOT) films were coated on fluorine-doped tin oxide (FTO) conductive glass by electrodeposition and applied as the counter electrode (CE) in dye-sensitized solar cells (DSSCs). Scanning electron microscopy (SEM) revealed the nanofiber-like structure of the PEDOT films. The maximum en…
Metamict minerals contain uranium and thorium, which contribute to physical degradation or metamictization of their crystal structures over geologic time. The damage occurs primarily through progressive overlapping recoil nuclei collision cascades from ɑ-decay of 238 U, 232 Th, 235 U, and their daughter products. We m…
OBJECTIVE: The aim of this study is to utilize the biocompatibility characteristics of biodegradable polymers, viz, poly lactide-co-glycolide (PLGA) and polycaprolactone (PCL), to prepare sustained-release injectable nanoparticles (NPs) of bone morphogenetic protein-2 (BMP-2) for the repair of alveolar bone defects in…
In this study, hybrid bulk heterojunction solar cells with an inverted architecture were fabricated using solution processing techniques. ZnO and TiO2 nanoparticles were then incorporated to the active layer which primarily consists of poly (3-hexylthiophene) (P3HT) and [6,6] phenyl-C61-butyric acid methyl ester (PCBM…
A vanadium complex (VO 2 (3-fl)) and CNT composite film based temperature sensor is reported in this study. Surface-type silver electrodes were deposited on the glass substrates. A thin film of VO 2 (3-fl) and CNT composite was coated as a temperature-sensing material on the top of the pre-patterned Ag electrodes. The…
Spin contamination in density functional studies has been identified as a cause of discrepancies between theoretical and experimental spectra of metal oxide clusters such as MoNbO2. We perform calculations to simulate the photoelectron spectra of the MoNbO2 anion using broken-symmetry density functional theory incorpo…
It is commonly thought that inhomogeneities in the bulk heterojunction thickness of donor:acceptor organic solar cells are a major efficiency‐limiting factor in scaling to modules. This is primarily related to degradation of the charge collection efficiency associated with the thicker segments of the active layer and/…
With the urbanization thriving in China, electric cables are gradually replacing the overhead line and widely used in urban distribution grid. Meanwhile, fault rate of electric cables has increased in recent years. Owing to the harsh environment the electric cables worked at, most of them experienced high humidity, ev…
The present study was carried out to investigate the potential of carboxylate group functionalized Multi-walled carbon nanotubes (MWCNT−COOH) adsorbent for the removal of Methyl orange (MO) textile dye from aqueous solutions. The effects of pH, shaking time and temperature on adsorption capacity were studied; the cont…
Resonance optical effects in ordered two-dimensional arrays of gold nanodisks embedded in an insulating magnetic film are investigated. The angle-resolved transmission spectra exhibit features related to the excitation of local surface plasmons and lattice plasmon polaritons in the gold nanoparticles and waveguide mod…
