The morphological evolutions of orthorhombic molybdenum oxide nanostructures with high crystalline nature have been successfully synthesized by combining low-temperature sol-gel and annealing processes. Strong influence of gelation temperature is a factor facilitated to control the material morphology. Morphological t…
The effect of the doped boron on the phase transition temperature between the monoclinic phase and the rutile phase of VO2 has been studied by performing first-principles calculations. It is found that the phase transition temperature decreases linearly with increasing the doping level of B in each system, no matter w…
Novel photoluminescent Bragg-reflective porous silicon, exhibiting dual optical properties, both the optical reflectivity and photoluminescence, was developed and used for sensing organic vapors. Photoluminescent Bragg-reflective porous silicon samples were prepared by an electrochemical etch of n-type silicon under t…
2 at% Mg doped thin films of delafossite CuCrO2 and Cr-deficient CuCr0.97O2 were prepared by pulsed laser deposition. The films were grown on c-sapphire single crystal substrates at a range of substrate temperatures, and the effects of the processing parameters on thin film properties were examined. The crystallinity…
The objective of this study is to evaluate the catalytic potential of metal oxide/MCM-41 catalysts in dicyclopentadiene oligomerization/dicyclopentadiene oligomer isomerization. Molybdenum oxide, tungsten oxide, and titanium oxide were loaded on MCM-41 using the modified atomic layer deposition method. The amount of t…
This paper discusses a new method for development of transparent high barrier biaxially oriented polyethylene terephthalate film via offline coating method. In the present research, a more efficient coating method was employed which reduces the cost of the developed film by 30–35% and minimizes the energy consumption…
Abstract We study the performance of a manganite sample meant for memresistive applications. In particular, we experimentally address the interplay between temperature and electrical noise the sample is subject to. Results reveal an optimum noise amplitude that maximizes the contrast between low‐ and high‐resistive st…
The structural dynamics during tensile deformation of rhodium (Rh) nanocontacts (NCs) at room temperature was observed by in situ high-resolution transmission electron microscopy. The critical shear stress for a {111}-(110) slip system was estimated from simultaneous measurement of the force acting on the NCs. It was…
Abstract Kinetic investigations for ozone conversion on three different series of zinc oxide catalysts, containing pure ZnO and doped with Mn or Cu one with dopant content less than 1 wt.% were carried out. The different samples were obtained from carbonate, nitrate and acetate precursors. The as prepared catalysts we…
ABSTRACT The disposal of paper mill sludge (PMS) is a difficult environmental problem. Thus, PMS has been used as a substitute for wood fiber (WF) to reinforce high‐density polyethylene (HDPE). In this study, we compared PMS–WF–HDPE composites with composites without PMS after water immersion and thermal treatment. Wa…
A complete and consistent set (elastic, dielectric, and piezoelectric tensors) of a commercial lead-free (YXt)-45° cut KNbO3 single crystal is reported. These data were obtained using several samples and the resonance-antiresonance method. Particular attention was paid to the consistency of this delivered database. A…
A diamine functionalized cubic mesostructured KIT-6 (N-KIT-6) has been prepared by post-synthetic method using calcined mesoporous KIT-6 with a diamine source, i.e., N-'[3-(tri methoxysilyl)- propyl]'ethylenediamine. The KIT-6 mesoporous silica used for N-KIT-6 was synthesized under weak acidic hydrothermal method usi…
We elucidate the evolution of forming nuclei leading towards a racemic molecular crystal by means of computer simulation. Our simulations start with the association of individual D- and L-norleucine molecules and subsequent formation of aggregates and thus provide molecular scale insights into the early stages of nucl…
CuO nanowire is an important one-dimensional semiconductor material to assemble and fabricate novel nanoelectronic device, especially molecular or atom device based on single nanowire. However, how to assemble and fabricate nanoelectronic device based on single CuO nanowire remains a big challenge. Here, we proposed a…
In this paper, we have reported the synthesize of CdS Nanoparticles through microemulsion mediated Triton X-100 neutral micelles at room temperature and its anti-biofilm activity against Escherichia coli. The encapsulated micelles nanoparticle system was studied for its absorption at 450 nm and emission spectrum was r…
A new type of light emitting nanorod that emits white light is reported.
A simple and robust alternative for fabricating stimuli-responsive 2D self-folding films was introduced. The approach combines metal-sputtering, layer-by-layer assembly of polyelectrolytes, and transfer-printing of the bilayer film onto a substrate coated with a sacrificial layer. With this technique, self-folding bil…
Al-TiO2 thin films were prepared using a sol-gel derived spin coating by varying the Al/Ti molar ratio from 0 to 0.73 to investigate the effect of Al doping on the optical band gap energy (Eg) of the films. GAXRD results indicated that Al-TiO2 is composed of anatase and FTO phases when the Al/Ti molar ratio was less t…
We present the potential realization of multiline optical filters by the integration of different periodic gratings, which are implemented on an HfO₂-on-silicon platform. Supporting arms are used to manage the relief of residual stress to obtain freestanding HfO₂ gratings. The spectral properties are calculated by the…
The phase diagram of ${(\mathrm{PbTiO}}_{3}{)}_{m}/{(\mathrm{BaTiO}}_{3}{)}_{n}$ ferroelectric superlattices was computed using the phase-field approach as a function of layer volume fraction and biaxial strain to tune ferroelectric properties through domain engineering. Two interesting domain structures are found: on…
