Objective: The main idea behind the present investigation is to explore the ability of Moraxella osloensis to reduce Titanium dioxide to nanosizes in a facile manner. Methods: The bacterium was grown in nutrient broth for 24 hr. The culture supernant was used for the bioreduction process. The synthesized nanoparticles…
High efficiency phase holograms are designed and implemented using aperiodic two-dimensional (2D) high-contrast gratings (HCGs). With our design algorithm and an in-house developed rigorous coupled-wave analysis (RCWA) package for periodic 2D HCGs, the structural parameters are obtained to achieve a full 360-degree ph…
ABSTRACT In order to improve the impact strength of PPS‐based strontium ferrite composite, the thermoplastic polyurethane (TPU) elastomer was added in the composite as a toughening agent. The composites were obtained by melt‐blending PPS, TPU and strontium ferrites in twin‐screw extruder. The crystalline state, therma…
The guided-mode resonance (GMR) concept refers to lateral quasi-guided waveguide modes induced in periodic layers. Whereas these effects have been known for a long time, new attributes and innovations continue to appear. Here, we review some recent progress in this field with emphasis on sparse, or minimal, device emb…
The crystal structure complex oxide Ba4Ca2Nb2O1 inanhydrous and hydrated forms was studied by the method of neutron diffraction, the preferred localization of protons were set. The hydration process with temperature variation and the partial pressure of water vapor was studied. It is established that the crystallograp…
Microfibers with their elongated shape and translation symmetry can act as important components in various soft materials, notably for their mechanics on the microscopic level. Here we demonstrate the mechanical response of a micro-object to imposed chirality, in this case, the tilt of disclination rings in an achiral…
Recently, a melt penetration process in which one kind of polymer melt severely penetrated by a second polymer melt is achieved in our home‐made multimelt multi‐injection molding instrument. The morphologies of polystyrene (PS)/polyethylene blends are observed to study the characteristics of melt flow during melt pene…
The gas phase hydrogenation of 3-butyne-2-one, an alkynic ketone, over two alumina-supported palladium catalysts is investigated using infrared spectroscopy in a batch reactor at 373 K. The mean particle size of the palladium crystallites of the two catalysts are comparable (2.4 ± 0.1 nm). One catalyst (Pd(NO 3 ) 2 /A…
We report a visible-blind ultraviolet photoconductive detector with interdigitated electrodes based on KTaO3 (KTO) single crystals. Both the steady spectral responses and the transient photovoltaic measurements clearly exhibit a cutoff wavelength at 344 nm (∼3.6  eV), in accordance with the bandga…
The extract of Capsicum have been evaluated as green extract for the corrosion of carbon steel in 1M HCl solution was investigated using weight loss, potentiodynamic polarization, ac electrochemical impedance spectroscopy (EIS), electrochemical frequency modulation (FEM) and energy dispersion spectroscopy (EDS) and sc…
A range of models of free standing and Ag(1 1 1)-supported stoichiometric ZnO films with coverages between 2-3 monolayers are studied using density functional calculations. Following experimental observations we focus on stoichiometric hexagonal and triangular ad-layer islands grown on top of two complete ZnO monolaye…
Abstract The key to utilizing quantum dots (QDs) as lasing media is to effectively reduce non‐radiative processes, such as Auger recombination and surface trapping. A robust strategy to craft a set of CdSe/Cd 1− x Zn x Se 1− y S y /ZnS core/graded shell–shell QDs with suppressed re‐absorption, reduced Auger recombinat…
Using molecular dynamics (MD) simulation, we study the temperature-induced [Formula: see text] phase transformation of an Fe[Formula: see text]Cr[Formula: see text] alloy. We find that the austenitic transition temperature is increased with respect to that of an Fe[Formula: see text]Ni[Formula: see text] alloy contain…
The influences of group 12 (Zn, Cd, Hg) metal-substitution on the valence spectra and phosphorescence parameters of porphyrins (P) have been investigated in a relativistic setting. In order to obtain valence spectra, this study reports the first application of the damped linear response function, or complex polarizati…
The molecular beam epitaxy (MBE) technique is well known for producing atomically smooth thin films as well as impeccable interfaces in multilayers of many different materials. In particular, molecular beam epitaxy is well suited to the growth of complex oxides, materials that hold promise for many applications. Rapid…
Summary The surface attachment of a porphyrin dye to nanocrystalline GaOOH was performed using two routes of solution‐based functionalization. The first method of functionalization utilized an in situ incorporation of dissolved porphyrin salt in solution during the microwave synthesis step. Additionally, synthesized G…
With the conservation of power, a phase diagram defined by amplitude square and phase of scattering coefficients for each spherical harmonic channel is introduced as a universal map for any passive electromagnetic scatterers. Physically allowable solutions for scattering coefficients in this diagram clearly show power…
GMA-SBRs with GMA contents in the range of 0.06–0.71 wt.% were synthesized and used to evaluate the properties of the silica composites for fuel-efficient tires. The chemical structures of the GMA-SBRs were analyzed using Fourier transform infrared spectroscopy, 1H nuclear magnetic resonance (1H NMR), size exclusion c…
Background: Diabetes is the growing health problem worldwide and increasing diabetes prevalence has been reported in the most countries. Several mechanisms are suggested for diabetic nephropathy that oxidative stress is the most important one. In this study efficiency of nanoceria (a potent antioxidant) was evaluated…
