The tryptophan fluorescence of bovine serum albumin (BSA) in solutions with different concentrations of cationic detergent cetyltrimethylammonium bromide (CTAB) at different pH is investigated, providing information on BSA denaturation under the action of CTAB. It is found that BSA denaturation under the action of CTA…
Composites comprising Poly(Methyl Methacrylate) (PMMA) and CaCu3Ti4O12 (CCTO) via melt mixing followed by hot pressing were fabricated. These were characterized using X‐ray diffraction, thermo gravimetric, scanning electron microscopy, and Impedance analyzer for their structural, morphology, and dielectric properties.…
Combustion calorimetry is used to measure the enthalpies of combustion and formation of azacyclooctan-2-one (I), azacyclononan-2-one (II), and azacyclotridecan-2-one (III) in the crystalline, liquid, and gaseous states. Conformational analysis is conducted, and quantum chemical calculations of the compounds’ enthalpie…
Vitex negundo is a common herb in different herbal formulation. The potential acute and sub-chronic dermal toxicities were evaluated as per OECD (Organization for Economic Cooperation and Development) guidelines 402 and 411, respectively. Both sexes of Wistar rats were exposed to Vitex negundo oil of 2000 mg/kg body w…
This paper presents a comparison of the macroscopic transformation strain evolution as a function of the bainite and martensite phase fractions in steels. Specifically, the evolution of anisotropic strain with phase fraction follows a linear trend for the martensitic transformation due to continuous stress-induced var…
Injectable and settable biomaterials are a growing class of therapeutic technologies within the field of regenerative medicine. These materials offer advantages compared to prefabricated implants because of their ability to be utilized as part of noninvasive surgical procedures, fill complex defect shapes, cure in sit…
Model evaluations of field-dependent leakage currents in the high-k dielectric oxides HfO2 and ZrO2 are presented. The treatment includes a number of competing transport processes on an equal footing. Our simulation results show that trap-assisted-tunneling, though important, is not the most significant contributor. T…
Recently, plexcitonic systems consisting of a plasmonic nanoshell or a core covered by an excitonic shell are engineered. Such systems hold promise for tunable nanophotonic devices for imaging, chemical sensing, and resonance energy transfer. Their plasmonic response is grasped well, while understanding of their excit…
We are in the middle of another revolution in information processing and distribution. After the invention of script and then print, pictures are taking over again. The number of gadgets with displays is larger than the world population. On average, every single person on earth owns at least one device with a display…
This paper provides a first report of a novel radial microchannel reactor (RMR) architecture for catalytic steam reforming of methane to hydrogen and/or synthesis gas. A bench-scale RMR prototype with a channel width of 0.700 mm and wash-coated with 0.030 mm of a Ni-based catalyst is operated at 750 °C and 11 bar with…
Cellulosomes, which are assemblies of cellulases with various catalytic functions on a giant scaffoldin protein with a carbohydrate-binding module (CBM), efficiently degrade solid cellulosic biomass by means of synergistically coupled hydrolysis reactions. In this study, we constructed hybrid nanocellulosomes from the…
Efficient modelling of the magneto-optic effects of transition metals such as nickel, cobalt and iron is a topic of growing interest within the nano-optics community. In this paper, we present a general discussion of appropriate material models for the linear dielectric properties for such metals, provide parameter fi…
This paper reports the bipolar resistive switching (RS) effect of the Nd 0.05 Bi 0.95 FeO 3 /Nb:SrTiO 3 heterostructure fabricated by pulsed laser deposition. This heterostructure shows a high RS ratio of over 600 at a read voltage of −0.3V after applying 5V/−8V pulse voltages. Moreover, the resistance states could be…
Orientational order of guest molecules in aligned liquid crystal 4-cyano-4′-pentylbiphenyl (5CB) is studied via optical dichroism and electron paramagnetic resonance (EPR) spectra measurements. The guest molecules used are bifunctional molecules bearing paramagnetic nitroxide group and photochromic azobenzene moiety.…
The excited states, ${}^{4}{T}_{2g}$ and ${}^{2}{E}_{g}$, of a Cr impurity in Al${}_{2}$O${}_{3}$ were treated by constraint density functional theory by imposing a density matrix constraint (constraint field) to control the electron occupation numbers of the $d$ orbitals. The calculated excitation energies, directly…
The hygrothermal effect on the flexural, interfacial and glass transition behaviors of 977-2A carbon/epoxy composites cured in an autoclave and by using Quickstep were evaluated in the previous paper. This article concerns with the hygrothermal effect on the mode I and mode II delamination resistance of the samples cu…
Doppelt gut: Die parallele elektrochemische Oxidation und Reduktion eines einzigen Polymers (P1) ergab simultan zwei korrespondierende Polymere (P2 und P3), die einfach zu trennen waren. Bei Bestrahlung mit UV-Licht unterschieden sich die Emissionen der P2- und P3-Filme drastisch von der von P1 (links). Parallele Reak…
Solvothermal reactions of CdCl2·2.5H2O with 4,4′-bis(benzoimidazol-1-yl)bibenzene (bimbb) and 1,4-benzenedicarboxylic acid (1,4-H2bdc), 4,4′-biphenyldicarboxylic acid (4,4′-H2bpdb), 5-methyl-1,3-benzenedicarboxylic acid (5-Me-1,3-H2bdc), or 1,3,5-benzenetricarboxylic acid (H3btc) afforded four 3-D metal–organic framew…
Purpose Ion‐exchange clays containing sodium such as bentonite and montmorillonite have the ability to exchange their cations. Few studies conducted with this type of ion‐exchange pigments are not conclusive about their anticorrosive efficiency. The present research aims to address the study on the anticorrosive effic…
Nanostripes with varying widths are lithographed on Co thin films with strong magnetic anisotropy resulting from the epitaxial growth onto vicinal Si(111) substrate. The competition between magnetocrystalline and shape anisotropies is used to tune the magnetic behavior of Co nanostripes. Single domain configuration is…
