We report a thermoelectric investigation of the stripe and superconducting phases of the cuprate ${\mathrm{La}}_{2\ensuremath{-}x}{\mathrm{Ba}}_{x}{\mathrm{CuO}}_{4}$ near $x=1/8$. We vary the doping and the magnetic field to identify features in the field-symmetric Nernst effect consistent with the reports of time-re…
This study is based on a numerical demonstration of energy and exergy analyses of a solar energy harvesting system based on the pyroelectric effect. The performance of a tryglycine sulfate (TGS) single crystal was investigated mathematically in the present study. The power output was optimized for different load resis…
We have studied the superconducting proximity effect in a series of e-beam evaporated Bi-Ni-Bi trilayers, where diffusion of Bi into Ni spontaneously formed superconducting NiBi3 layers at both Ni-Bi interfaces, effectively resulting in superconductor-ferromagnet-superconductor (S-F-S) trilayers. The thickness of top…
We use molecular dynamics phonon wave packet (WP) simulations to study acoustic propagation and attenuation in amorphous silica $(a\text{\ensuremath{-}}\mathrm{Si}{\mathrm{O}}_{2})$ at frequencies near the boson peak (BP) position and compare them with the results of equilibrium molecular dynamics (EMD) simulations. T…
Abstract The gas‐phase dehydration of aqueous glycerol to acrolein was investigated using phosphorus‐containing MCM‐41 (HP‐MCM‐41) mesoporous molecular sieves, which were prepared via impregnation of phosphoric acid on the MCM‐41. The catalysts were characterized by XRD, nitrogen adsorption‐desorption, FTIR, NH 3 ‐TPD…
In situ forming redox responsive nanoparticles have been developed based on amphiphilic copolymers-phototriggered disulfide-cross-link macromolecules (PDCM). Upon 405 nm light irradiation, the macrocyclic thiol caged coumarin phototrigger in PDCM can release free thiols, and these free thiols subsequently realize in s…
Understanding and apprehension of the characteristics and circumstances in which mesenchymal stem cells (MSCs) affect and make alterations (enhance or reduce) to the growth of tumors and metastasis spread is pivotal, not only for reaching the possibility to employ MSCs as drug delivery systems, but also for making for…
Novel P(VDF-TrFE)/organosilicate composite membrane was fabricated by electrospinning. The electrospun composite membrane containing as little as 2 wt% of organosilicate demonstrated significant improvements in strength, modulus, and toughness by about 103%, 45%, and 97%, respectively, when compared with those of elec…
This paper was designed to test the feasibility of optical identification of trace amounts of narcotics in serum using photoinduced delayed luminescence (DL). Comparative investigation of control serum and contaminated samples with methamphetamine and heroin was conducted. For the control serum without chemical contam…
Future mobility applications are characterized by a high level of resource efficiency due to the application of novel lightweight materials and function‐integrating, multi‐material design concepts. Textile thermoplastic composites in particular pave the way for lightweight components characterized by highly specific m…
In this work, an alternative technique to the traditional micromechanical exfoliation of two-dimensional materials is proposed, consisting of isolated flakes of graphite and molybdenum disulphide onto polymeric surfaces films. The set made up of polymer and flakes is fabricated by using a hot-press machine called poly…
In this work, viscosities of ternary Au–Ag–Cu and Al–Cu–Si liquid alloys have been calculated as a function of gold, aluminium and copper compositions for the sections Au–Ag–Cu (xAg/xCu = 0.543 at 1373 K), Alx(Cu50–Si50)(1–x) and Cux(Al50–Si50)(1–x) at 1375 K using Chou’s general solution model, Muggianu, Kohler, Toop…
Abstract Combined experimental and theoretical study on the electronic characteristics of tetrathiahelicene (7‐TH) alkyl and aryl phosphorus derivatives, including phosphanes, phosphine–borane complexes, phosphine oxides, and phosphine–selenides, is described. The collected data give useful information on the σ‐donor…
A number of thin silicon films are deposited on crystalline silicon, native oxidized crystalline silicon, and optical quality fused quartz substrates through the use of ultra-high-vacuum evaporation at growth temperatures ranging from 98 to 572 °C. An analysis of their grazing incidence X-ray diffraction and Raman spe…
Force fields for molecular simulation are generally optimized to model macromolecules such as proteins at ambient temperature and pressure. Nevertheless, elevated temperatures are frequently used to enhance conformational sampling, either during system setup or as a component of an advanced sampling technique such as…
Rheologically complex materials are described by function-valued properties with dependence on a timescale (linear viscoelasticity), input amplitude (nonlinear material behavior), or more generally both (nonlinear viscoelasticity). This complexity presents a difficulty when trying to utilize these material systems in…
Among the langasite family, Ca 3 TaAl 3 Si 2 O 14 (CTAS) is particularly promising for high temperature sensor applications due to its relatively high resistivity. In this work, CTAS single crystals have been grown by the Czochralski technique under various oxygen partial pressures using Ir and Pt crucibles. Colorless…
Ability to digitally control the amount of a deposited material is one of the many advantages of inkjet printing. In this letter, we demonstrate the applicability of inkjet printing for the fabrication of depletion-load nMOS inverters based on metal oxide thin-film-transistors (TFTs) from printed metal oxide precursor…
This paper presents a study of the quartz fibrous filters used as a substrate for capturing the particulate matter (PM) present in the air. Although these substrates are widely used in environmental applications, their microstructure has been barely studied. The behavior of these devices during the filtration process…
Understanding how surface plasmon polaritons (SPPs) propagate in metal nanostructures is important for the development of plasmonic devices. In this paper, we study the transmission of SPPs between single-crystal gold nanobars on a glass substrate using transient absorption microscopy. The coupled structures were prod…
