Nb ‐doped TiO 2 ( TNO ) films, which are highly conductive and transparent, can be used as transparent conductive oxide ( TCO ) films. A predominant manufacturing method for TCO film is magnetron sputtering, and the material of the sputtering target affects the performance of the film. The objective of this study was…
Co‐Mn‐O composite oxide nanosheet catalyst was successfully prepared using a facile urea‐assisted one‐step hydrothermal method in the absence of organic or organic templating reagent. Co‐Mn‐O nanosheet catalyst was optimized by varying hydrothermal process parameters such as molar ratio of Co‐Mn to urea, hydrothermal…
This work reports the formation of self-organized Zircaloy-4 (Zr-4) oxide nanotubes in viscous organic ethylene glycol (EG) electrolyte containing a small amount of fluoride salt and deionized (DI) water via an electrochemical anodization. The structure, morphology, and composition of the Zr-4 oxide nanotubes were stu…
CuAl 1/2 Fe 1/2 O 2 delafossite was prepared using a solid‐state reaction method to investigate its optical and electronic transport properties. CuAl 1/2 Fe 1/2 O 2 formed a hexagonal delafossite structure with an R m space group. The positive Seebeck coefficient and the direct optical gap of 3.6 eV confirmed that the…
ABSTRACT The achievement of optimum adhesion between a thermoset and an inorganic material is an important goal for the composites and coatings industries. There is a growing interest in the use of structural surface modifiers, such as nanotubes, nanoparticles, and whiskers, to improve this adhesion. Here, a method fo…
ABSTRACT The absorbable porous material, especially gelatin porous film, is widely used for surgical use to stop bleeding, but its price is quite high. Thus, a new material at lower price with desirable properties is required. This article presents an approach to prepare a porous film of silk fibroin–rice starch (SF–R…
ABSTRACT Poly(lactic acid)/2 wt % organomodified montmorillonite (PLA/OMMT) was toughened by an ethylene‐methyl acrylate‐glycidyl methacrylate (E‐MA‐GMA) rubber. The ternary nanocomposites were prepared by melt compounding in a twin screw extruder using four different addition protocols of the components of the nanoco…
ABSTRACT Depolymerized polyethylene terephthalate and liquefied wood polyesters can be used as a polyol for the production of polyurethane/polyisocyanurate foams. In this research, liquefied wood was synthesized by using a combination of diethylene glycol and glycerol and due to the possibility of using glycerol that…
Work function engineering, a precise tuning of the work function, is essential to achieve devices with the best performance. In this study, we demonstrate a simple technique to deposit graphene on insulators with in situ controlled boron doping to tune the work function. At a temperature higher than 1000 °C, the boron…
Abstract Albendazole (ABZ), a well-established antiparasitic drug, has been shown to suppress tumor growth in a number of preclinical models of cancer. However, the low solubility of ABZ limits its use as a systemic anticancer agent. To enable systemic administration, we have formulated ABZ into albumin nanoparticles…
The model organism for polyhydroxybutyrate (PHB) biosynthesis, Ralstonia eutropha H16, possesses multiple isoenzymes of granules coating phasins as well as of PHB depolymerases, which degrade accumulated PHB under conditions of carbon limitation. In this study, recombinant Escherichia coli BL21(DE3) strains were used…
Poly(1,4-butylene adipate) (PBA), poly( l -lactic acid) (PLLA), and poly( d -lactic acid) (PDLA) are biodegradable and environmentally friendly polymers. PLLA- and PDLA-formed stereocomplex crystallites (SCs) by solvent-casting served as nucleating agents of PBA. The isothermal crystallization kinetics and morphology…
During sintering of tape cast products, anisotropic shrinkage occurs, which can be attributed to an anisotropic green tape structure concerning particle and pore orientation. Little is known about the shrinkage during binder burnout ( BBO ) and its relation to the microstructure of green tapes including the binder–pla…
Electrospinning provides a promising route to quickly produce high‐purity ceramic fibers from readily available sol–gel precursors. Recently, techniques have been developed to enable the production of biphasic nanocomposites on a single fiber, enabling the development of novel composites with connectivities that are d…
Sintered ceramics of β‐ Sr 2 SiO 4 : Eu 2+ , R 3+ ( R = Tm , Gd ) were prepared and their spectroscopic properties were evaluated. A large enhancement of green photostimulated luminescence ( PSL ) was observed from β‐ Sr 2 SiO 4 : Eu 2+ codoping with Tm 3+ at a recognizable intensity level, and the most efficient PSL…
This paper is aimed to fill the void in the literature regarding the temperature‐dependent ideal tensile strength of the AlB 2 ‐like diborides. To this end, two models of temperature‐dependent ideal tensile strength of hexagonal single crystals are developed based on the critical failure energy density principle and t…
The composition of the borosilicate glass layer formed during oxidation of ZrB 2 ‐30 vol% SiC was determined to elucidate the extent of B 2 O 3 retention in the oxide during high‐temperature oxidation. Oxidation was conducted in stagnant air at 1300°C, 1400°C, and 1500°C for times between 100 and 221 min. Specimens we…
Large metal-oxo clusters consistently assume spherical or regular polyhedral morphologies rather than high-aspect-ratio structures. Access to elongated core structures has now been achieved by the reaction of lanthanoid salts with a tetrazole-functionalized calixarene in the presence of a simple carboxylate co-ligand.…
In this study, we investigated the role of the chemical nature of the oil droplet core of nano-emulsions used as contrast agents for X-ray imaging on their pharmacokinetics and biodistribution. To this end, we formulated PEGylated nano-emulsions with two iodinated oils (i.e., iodinated monoglyceride and iodinated cast…
By measuring the curvature of thin disks of vitreous silica that have been penetrated by water from one side only, we determined the volume expansion of the silica and the effect of this volume expansion on its strength. We found that the water‐strengthening process depended on crack‐size, temperature, and the amount…
