In this paper, gas sensing property of a nitrogen doped ZnO was studied. nanofilms of pure and nitrogen-doped ZnO (0.1, 0.2 and 0.3 normality) were prepared on glass substrate by spray pyrolysis technique. These films were fired at 450°C for two hours in air atmosphere. nanobehavior of the films was confirmed by XRD a…
Abstract Diadesmis fukushimae, a rare oligotraphenic diatom, was found in some high mountain lakes of Romania. Its occurrence in the Parâng and Retezat Mountains is the second European record of the species. To date D. fukushimae has been known only from the type locality (Shenandoah National Park, Virginia, USA) and…
Micro-nano patterned surfaces have significant applications in various fields as they behave differently under the effect of catalysts, magnetic energy, electronic emission/absorption, optics and biological cells. Engineering these topologies demands a better understanding of the contact angle. The current contact ang…
Spin-polarized current and tunneling magnetoresistance (TMR) are studied for two lengths of phenyl based molecules using Green's function formalism. The Hückel method is used for describing the Hamiltonian of the molecules. Our results show that an increase in length of the BPDT molecule leads to an increase in the sp…
Rechargeable magnesium batteries have attracted attention for use in the nextgeneration power storage applications. V2O5 xerogel, which has a high capacity, is expected to be an active cathode material for magnesium rechargeable batteries. However, it faces the problem of degradation due to desorption of structural wa…
This article presents shot-peening effect on the structure, microhardness, and compressive stresses of the austenitic steel 1.4539. The research shows strengthening of the top layer and the formation of compressive stresses in the subsurface layers of the shot-peening elements.[b]Keyword[/b]: austenitic steel 1.4539,…
Hierarchical lamellae self‐assembled from linear multiblock copolymers in thin films are investigated by self‐consistent field theory. The thin films are confined between two parallel substrates. The confinement strategy allows generating hierarchical microstructures with various numbers and different orientations of…
Prevulcanised natural rubber latex (PvNRL)/banana stem powder (BSP) composite films were prepared by adding various amounts of 10%BSP dispersion. The properties of the resulting prevulcanised (PvNRL)/BSP composite films were compared with those films containing the same amounts of calcium carbonate (CaCO3). The PvNRL/…
Experimental measurements of colloidal crystallization in a wide range of volume fractions of charged particles were performed to investigate the liquid-metastable-stable transition process. To fit the obtained experimental data, we developed a theoretical model to formulate the kinetics of the concurrent liquid-metas…
The charge-transfer compound ${(\mathrm{BEDT}\ensuremath{-}\mathrm{TTF})}_{2}\mathrm{Ag}{({\mathrm{CF}}_{3})}_{4}(\mathrm{TCE})$ crystallizes in three polymorphs with different alternating layers: While a phase with a $\ensuremath{\kappa}$ packing motif has a low superconducting transition temperature of ${T}_{c}=2.6\…
Hot-deformed Nd-Pr-Fe-B-based nanocomposite magnets with different values of compressive true strain ε were prepared by the die-upset method. The crystallographic texture quantified as the X-ray diffraction intensity ratio of (004) to (220) peaks of the (Nd, Pr)2Fe14B phase increased from 0.6 for ε = 0 to 2.06 for ε =…
Broadband transparent electrodes based on 2D hybrid nanostructured Dirac materials between Bi2 Se3 and graphene are synthesized using a chemical vapor deposition (CVD) method. Bi2 Se3 nanoplates are preferentially grown along graphene grain boundaries as "smart" conductive patches to bridge the graphene boundary. Thes…
Abstract Polyethylene of fibrous morphology was obtained using Cp 2 VCl 2 and VCl 2 ( salenCl 2 ) catalysts activated by AlEt 2 Cl and AlEtCl 2 and heterogenized on a supported ionic liquid system prepared with SiO 2 and 1‐(3‐triethoxysilyl)propyl‐3‐methylimidazolium chloroaluminate. The fibre length ranges from 15 to…
A coupled-wave analysis of the particularly low-loss 0th- and -1st-order switching triggered by the +1st- and -2nd-order excitation of the surface plasmon of an undulated metal surface reveals that the cancelation of the -1st-order diffraction efficiency is due to the destructive interference between the field directl…
Abstract Novel bio‐based and biodegradable electrospun membranes, containing bactericidal ricinoleic acid (RA) units either by copolymerization with butylene succinate (BS) units or by blending PRA and PBS homopolymers, are characterized in their chemical, thermal, mechanical and surface properties. In the blends E. c…
Spandex is increasingly used in either every course or alternating courses of knitted fabrics to impart a greater level of stretch and form stability than that can be achieved with cotton alone. The incorporation of spandex to the fabric structure effects many of the fabric properties. In this study, 100% cotton, half…
We report catalyst-free growth of high-density single-sided ZnO nanocombs for the first time on a multi-layer graphene (MLG). Structural analysis based on scanning electron microscope reveals the nanocomb ribbon average diameter and length are about 90–600 nm and 5–60 μm, respectively, while the diameter and length of…
Spin polarization and stacking are interesting effects in complex molecular systems and are both presented in graphene-based materials. Their possible combination may provide a new perspective in understanding the intermolecular force. The nanoscale graphene structures with zigzag edges could possess spin-polarized gr…
A surface potential-based low-field drain current compact model is presented for two-dimensional (2D) transition metal dichalcogenide (TMD) semiconductor field-effect transistors that takes into account the effect of interface trap states on device current–voltage ( I ds – V gs ) characteristics and transconductance g…
We fabricated a series of mesoporous silicas and mesoporous organosilicates with hierarchical porosity through evaporation-induced self-assembly using Pluronic F127 as a template in this study. We could tailor the mesophase of each mesoporous silica sample by varying the weight ratio of its two silica sources: tetraet…
