Boron Nitride Nanotubes (BNNTs) possess extremely high stiffness and strength and may provide the ultimate reinforcing materials for the development of nano-composites. In this paper, the Young's modulus of BNNT based composites are evaluated using a 3-D nanoscale representative volume element (RVE) based on continuum…
In this report, we describe a synthesis of high quality infrared emitting HgSe quantum dots using a variety of room temperature routes, resulting in particles of various morphologies.
The dehydration of mildronate dihydrate (3-(1,1,1-trimethylhydrazin-1-ium-2-yl)propionate dihydrate) was investigated by powder X-ray diffraction, thermal analysis, hot-stage microscopy, water sorption–desorption studies and dehydration kinetic studies. It was determined that mildronate dihydrate dehydrated in a singl…
The soft-shelled turtle (Pelodiscus sinensis) is a commercially important aquatic species with abundant collagen content and precious nutritious high quality goods. The present study was to optimize the collagen extraction from lung of Pelodiscus sinensis. Single-factor test was employed to investigate the effects of…
Well-defined multifunctional lipid-polymer conjugates as new tools for the functionalization of lipid assemblies.
The development of multifunctional, low density graphene–metallic hybrid foam is demonstrated by a feasible method.
Sea urchins possess a set of five teeth which are self-sharpening and which continuously replace material lost through abrasion. The continuous replacement dictates that each tooth consists of the range of developmental states from discrete plates in the plumula, the least mineralized and least mature portion, to plat…
The location of nanoparticles is a straightforward reflection of the nucleation sites of graphene growth. The deposition of nanoparticles is consistent with the distribution of multilayer graphene.
The effect of grain size on fracture toughness was investigated for a wrought AZ31 magnesium alloy. The grain size was refined by equal channel angular pressing (ECAP) progress. Digital image correlation (DIC) was used to determine the fracture property. The fracture toughness was found to be improved by grain refinem…
In order to develop inks suitable for roll-to-roll printing processes, which can be cured into in situ electrolyte filled high porosity macroporous polymer membranes, non-aqueous high internal phase emulsions (HIPEs) were prepared. The external phase of the formulated HIPEs consisted of lauryl methacrylate (LMA) and 1…
An effective approach for fabricating silane-functionalized TiO <sub>2</sub> nanoparticles/silicone resin (SR) composites that exhibit high transparency, high refractive indexes (RIs), high UV aging resistance, and high moisture barrier.
We synthesized the lithium-tetragermanate (Li2Ge4O9) phase doped with Mn4+ by glass-ceramics technique using the stoichiometric glass-precursor with different MnO2 concentrations, i.e., 20Li2O–80GeO2–xMnO2 (x = 0.1–0.7), and examined their photoluminescent property. The doped phase showed clear red-emission at room te…
Here, we report an efficient method for the transformation of waste car bumpers into mesoporous magnetic carbon material. Nearly 25 wt% of polypropylene was transformed into carbon material when an optimized amount of catalysts was introduced into the bumper composite. In addition, due to the presence of Fe and Co nan…
2,4-Dinitrobenzenesulfonic acid as an efficient Brønsted acidic catalyst has been evaluated for the controlled/living ring-opening polymerization of ε-caprolactone end-functionalized, α,ω-dihydroxy telechelic poly(ε-caprolactone), and diblock copolymers were also synthesised successfully.
The possibility of creating new polymers with desired properties is now harder, so there is great place for modification of known thermoplastic with addition of fillers. At conventionally used fillers such as talc, calcium carbonate or glass fibers is normal degree of filling up to 40%. New nanocomposite fillers can i…
High-temperature tensile deformation was performed using ODS ferritic steel, which has grain structure largely elongated and aligned in one direction, in the direction perpendicular to the grain axis. In the superplastic region II, two-dimensional grain boundary sliding (GBS) was achieved, in which the material did no…
Active implantable medical devices (IMD) for the monitoring and treatment of transient disease states have garnered increasing interest in the medical research community. In order for these technologies to be fully viable, they require a similarly biodegradable energy source. This study presents a series of MEMS-enabl…
Colloidal quantum dot (QD) purification is typically conducted via repeating precipitation-redispersion involving massive amounts of organic solvents and has been the main obstacle in mass production of QDs with dependable surface properties. Our results show that the electric field apparently affects the streamlining…
In this study, the synthesis of polyethylenes has been carried out with titanium-magnesium supported Ziegler-Natta catalysts in laboratory-scale reactors. A correlation of different polymerization conditions with thermal and mechanical properties of polyethylenes has been established. It is seen that there is lowering…
The acidity of the solution can alter the crystal's shape and structure of the coatings grown at 95 °C controlling their electrochemical performance.
