Results regarding optical and structural properties of Cu 2 ZnSnS 4 (CZTS) thin films prepared by co-evaporation using a novel procedure are compared with those obtained with CZTS films grown using a solution based route. The lattice strain ε and crystallite size D of CZTS films prepared by co-evaporation and by spray…
Biosurfactants are molecules with emulsifying and surface-active properties that have environmental and industrial applications in the pharmaceutical, food, cosmetic, and cleaning industries. These biomolecules are a prominent topic for research and development since they are possible replacements for synthetic surfac…
The microwave magnetic-field tunable filtering properties in a multichannel filter based on use of a one-dimensional finite magnetized plasma photonic crystal (PPC) are theoretically investigated. The considered PPC has a structure of air/(AB)N/air, where A is a dielectric layer, B is a plasma layer, and N is the stac…
We report variable and unique properties of 1,2-di(9-anthryl)benzene 1 as a fundamental moiety of anthracene-based π-cluster molecules. Due to a through-space π-conjugation between anthracene units, excimer emission at room temperature and charge delocalized state in radical cation state of 1 could be observed. Photoi…
Hydrophobins are fungal proteins whose functions are mainly based on their capability to self-assemble into amphiphilic films at hydrophobic-hydrophilic interfaces (HHI). It is widely accepted that class I hydrophobins form amyloid-like structures, named rodlets, which are hundreds of nanometers long, packed into orde…
Organic–inorganic hybrid perovskites play an important role in improving the efficiency of solid-state dye-sensitized solar cells. In this paper, we systematically explore the efficiency-enhancing mechanism of ABX 3 ( A = CH 3 NH 3 ; B = Sn, Pb; X = Cl, Br, I) and provide the best absorber among ABX 3 when the organic…
A photonic crystal’s refractive index sensor is proposed based on the photonic crystal (PC) optical properties and the surface wave resonance principle. The optical Tamm state existing at the interface between one-dimensional (1D) PCs and the metal layer can overcome the disadvantage of the surface plasmon resonance (…
The dynamic response of a homogeneous half-space, with a traction-free surface, is considered within the framework of non-local elasticity. The focus is on the dominant effect of the boundary layer on overall behaviour. A typical wavelength is assumed to considerably exceed the associated internal lengthscale. The lea…
The correct determination of the phase transition behaviour of phase change materials (PCMs) is paramount for assessing their application potential. In this work, the merits of a novel calorimetric technique, Peltier-element-based adiabatic scanning calorimetry (pASC), for PCM characterisation are investigated, especi…
Layered lithium transition metal oxides with optimized nickel–manganese content are nowadays of primary interest as electrode materials for lithium ion batteries, since they are able to deliver a high capacity at a low cost. Herein we report a new class of less expensive cathode materials, which comprise sodium-defici…
Semiconductor TiO2 photocatalysis has attracted much attention due to its potential application in solving the problems of environmental pollution. In this paper, thiourea (CH4N2S) modified anatase TiO2 nanorods were fabricated by calcination of the mixture of TiO2 nanorods and thiourea at 600 °C for 2 h. It was found…
For the enhancement of insulation strength in vacuum, spark conditioning is an important and effective method. In order to enhance the insulation performance of vacuum circuit breakers, we have to clarify the conditioning effect and improve a conditioning procedure. In this paper, we discuss the conditioning process o…
Although a number of experiments have been attempted to investigate the lubrication of aqueous copolymer lubricant, which is applied widely in metalworking operations, a comprehensive theoretical investigation at atomistic level is still lacking. This study addresses the influence of loading pressure and copolymer con…
Crystals of superconducting ${\mathrm{Mo}}_{8}{\mathrm{Ga}}_{41}$ $({T}_{c}=9.8\phantom{\rule{0.16em}{0ex}}\mathrm{K})$ and ${\mathrm{Mo}}_{8\ensuremath{-}x}{\mathrm{V}}_{x}{\mathrm{Ga}}_{41}$ limited solid solution $[{x}_{\mathrm{max}}=1.9(2)]$ have been grown from the high-temperature Ga flux and confirmed to have t…
This research work was conducted to characterize boride phases, obtained from the powder-pack process, on AISI H13 and D2 steel substrates, and investigate their tribological behavior. The boriding was developed at a temperature of 1273 K with an exposure time of 8 h. X-ray diffraction, scanning electron microscopy, a…
Abstract A novel sustainable approach to valued γ‐valerolactone was investigated. This approach exploits the visible‐light‐mediated conversion of biomass‐derived levulinic acid by using a bimetallic catalyst on a graphitic carbon nitride, AgPd@g‐C 3 N 4 .
This article describes a method of predicting the failure of a thermal barrier coating system due to interfacial cracks and cracks within bulk coatings. The interfacial crack is modelled by applying cohesive interfaces where the thermally grown oxide is bonded to the ceramic thermal barrier coating. Initiation and pro…
Carbon dioxide was photocatalytically reduced to produce methanol and ethanol in the presence of CuO-loaded titania powders suspended in water containing Na2SO3 as the hole scavenger. The photocatalysts were synthesized by an impregnation method using P25 (Degussa) as support. At the optimum amount of copper oxide loa…
BACKGROUND AND AIMS: Every year, in Europe, acute myeloid leukemia (AML) is diagnosed in thousands of adults. For most subtypes of AML, the backbone of treatment was introduced nearly 40 years ago as a combination of cytosine arabinoside with an anthracycline. This therapy is still the worldwide standard of care. Two-…
The facile preparation, aqueous stability, and hydrolysis characteristics of amorphous cellulose regenerated from cellulose solutions using amine/inorganic salt solvents was investigated. Highly crystalline cellulose was dissolved in a mixture of ethylenediamine and NaSCN, KSCN, or NaI at room temperature; subsequent…
