Porous metallic structures have been developed to mimic the natural bone architecture, having interconnected porosity, disposing enough room to cell migration, anchoring, vascularization, nourishing and proliferation of new bone tissue. Research involving porous titanium has been done with purpose to achieve desirable…
Abstract In this work we propose a super Fringe‐Field Switching (FFS) structure in which groove is formed between electrodes. With groove structure, both the threshold voltage V th and operation voltage V op of LCD display decrease by about 0.5 V. These improvements make great contribution to the power consumption of…
Polylactic acid (PLA), a bioplastic, is a hard resin, and has to be softened in order to be used in electric wire sheaths. We added a soft resin to PLA in order to soften it, but this caused decreases in the electric breakdown strength (EB). In this study, we irradiated soft resin-added PLA with an electron beam and e…
Synthetic Polymers, both organic and inorganic, are used in a wide variety of biomedical applications. The polymers can be biodegradable or nondegradable. Chitosan (CH), which is a naturally biodegradable, non-toxic biopolymer obtained by the deacetylation of chitin, has been demonstrated to have an intrinsic activity…
In this study, four model drugs, i.e., Meloxicam (MEL), Risperidone (RIS), Eprinomectin (EPR), and Bull Serum Albumin (BSA), were encapsulated in PLGA microspheres via solvent evaporation methods. The encapsulation efficiency and in vitro release profiles of different drugs with various water solubilities from medicat…
This work had the aim to optimize the synthesis process of a geopolymer using experimental planning of mixtures. The geopolymer was prepared with different proportions of bauxite mud (R), rice husk ash (C) and metakaolin (M). The aluminosilicatealkaline activation was made with sodium hydroxide (NaOH) solution of 12 m…
Polarization and depolarization current measurement is a non-destructive testing method to study the dielectric properties of insulating materials. Two kinds of mineral oils with different aging time have been measured and compared. When the charge carriers drift to the electrodes, they may be blocked and accumulated…
Abstract Colloidal CuInS2 based nanocrystals emerge as low cost, low toxic, non‐rare earth color conversion materials to enhance the performances of white lighting emitting diodes. We here report the fabrication of light conversion films composed by CuInS2/ZnS nanocrystals and PMMA as well as their applications in int…
Literature data regarding the influence of arsenic on the corrosion resistance of low-carbon low-alloy steel are analyzed. A mechanism explaining this influence in air and in sea water is proposed.
Taking aluminum sulfate and urea as the raw materials produce α-Al2O3 in different shapes by employing the hydrothermal-pyrolysis method. The study analyzes the characterization of the products by XRD and SEM, and explores the effects exerted by factors like time span of the hydrothermal reaction and additives such as…
The adsorption of hydrogen on the (001) and (110) surfaces of the PdFe alloy has been investigated using the projector-augmented-wave method within the generalized gradient Perdew-Burke-Ernzerhof (PBE) approximation for the exchange-correlation functional. The most preferred sites of hydrogen adsorption on the two sur…
Las baterías de automóviles no solo son afectadas por el uso y desgaste, sino también por otros factores como la concentración del electrolito, la pérdida de agua y la temperatura a la que puede estar expuestas, siendo este último el factor de mayor influencia permitiendo así un incremento en la velocidad de corrosión…
Abstract We demonstrated a liquid crystal (LC) microlens array by assembling the phase separation morphology of liquid crystal (LC) and liquid monomer using a fringing field. The prepared lenticular microlenses can present a switchable focus with good optical characteristics. Our lenticular microlens array has promisi…
A new approach to measure the local response of micropatterned CdTe based solar cells is presented. This method provides fast results with high spatial resolution and the ability to map short circuit current (Ish), open circuit voltage (Voc), maximum power, and fill factor. It is based on consecutive photoconductive a…
Abstract Some specially designed metallic alloys crystallize during process of rapid quenching which aims their amorphization. Nevertheless, change in their mechanical properties could be seen compared to these obtained during conventional technological regimes of cooling. That attracts the attention in this elaborati…
Gelatin methacrylate (GelMA) hydrogel comprised of modified natural extracellular matrix (ECM) components, making it a potentially attractive material for surface modification. In this paper, we hypothesize that establishing a GelMA hydrogel coating on titanium surface will accelerate osseointegration. Titanium substr…
As shown by J. Shi, W. Bu, and co-workers on page 3867, ultrasmall NaGdF4 nanodots (ca. 2 nm) with diethylenetriaminepenta-acetic acid (DTPA) conjugation are synthesized for efficient magnetic resonance (MR) angiography. Impressively, the r1 value in magnetic resonance imaging (MRI) reaches up to 8.93 mM−1 s−1. The ul…
A finite element model ships, for example design test condition of the underwater explosion, selection of explosive package quantity is 1000KG TNT, the explosive location along the direction of the ship with the bow, midship and stern, the angle of attack in three exploded cross section have 90 degrees, 60 degrees, 45…
Coal-tar pitch, a feedstock which can be heat-treated to create graphite, is composed of very complex molecules. Coal-tar pitch is a precursor of many useful carbon materials (e.g., graphite, carbon fibers, electrodes and matrices of carbon/carbon composites). Modified coal-tar pitch (MCTP) was prepared using two diff…
Abstract An ultra‐thin shadow mask plasma display panel is suitable for double‐sided display and 3D display. A self‐consistent fluid model is used to analyze the discharge characteristics of the ultra‐thin SMPDP cell. The discharge processes of ultra‐thin SMPDP and normal SMPDP are almost same proved by fluid model an…
