In ultrathin Cu(In,Ga)Se2 (CIGS) film solar cells, the CdS/CIGS interface may become one of the limiting factors for efficiency. The first step toward reducing the impact of this problem could be a surface treatment process to improve the quality of the front interface. The purpose of this study is to have a better un…
The correlation of several defects and optical and magnetic properties with Fe content in Zn1−xFexAl2O4(0.01 ≤x≤ 0.40) nanocrystals has been scrutinized through X-ray diffraction, OK-edge X-ray absorption near-edge structure, FT–IR, diffuse reflectance, photoluminescence and electron spin-resonance spectroscopies, and…
Both liming and plant residue incorporation are widely used practices for the amelioration of acidic soils—however, the difference in their effects is still not fully understood, especially regarding the microbial community. In this study, we took the acidic soils from a subtropical orchard as target soils, and implem…
Sintered ores with superior high-temperature reducibility can enhance indirect reduction at the shaft and permeability at the cohesive zone through improving the softening-melting behavior, resulting in stable operation of the blast furnace at low coke rates. As the depletion of high-grade ore deposits limits control…
The sulfide morphology in free-machining ferritic stainless steel was investigated and the mechanism of monotectic sulfide formation was evaluated. Metastable monotectic sulfide containing oxygen was mainly observed. The decrease in sulfide activity by dissolved oxygen can be considered to contribute to the formation…
It was for the first time that the complex compound of gallic acid with titanium (IV) salt was used as a precursor to synthesize titania nanotubes. The study was separated into four main sections; (I) synthesizing the complex of titanium with gallic acid, (II) synthesizing anatase and rutile phases through thermal dec…
Complex structures, large size and limited manipulation of acoustic waves are the problems that restrict the development of acoustic metasurfaces. Here, we report a transmission-type acoustic metasurface based on local resonance mechanism, which is composed of meta-atomic units called dumbbell-shaped double-split holl…
The oxygenic photosynthetic activity (OPA) of an alkaliphilic microalgae consortium was evaluated at different concentrations of dissolved sulfide under room temperature and well-defined conditions of irradiance and pH in a tubular closed photobioreactor. The kinetic assays showed that it was optimal at a sulfide conc…
The strengthening mechanism of microalloyed vanadium (V) on eutectoid pearlite steel was investigated from the perspectives of nano-precipitation and lattice strain. The 0.2% proof stress of specimens, isothermally transformed at 873 K, increased by about 160–170 MPa with the addition of 0.1% V. However, the interphas…
In this paper, sulfonic groups functionalized annealed bio-based carbon microspheres loaded polytetrafluoroethylene (A-BCMSs-SO3[email protected]) fibers with high activity, high stability, and easy regeneration were successfully fabricated by a simple method using low-cost raw materials. The characterization results…
The microstructure and tensile behavior of stir zones in the friction stir welded brass plates containing disordered secondary β phase at different heat inputs were investigated. At high heat inputs, β was transformed completely to α, and hence the final microstructure was single-phase. At lower heat inputs, fine β pa…
Industrial printing production of organic solar cells (OSCs) requires high power conversion efficiency (PCE) with wide toleration of active layer thickness. Herein, high‐efficiency thick‐film OSCs are demonstrated using a polymer fibril network strategy (FNS), which involves a donor polymer (PT2) that can self‐assembl…
Abstract A significant amount of attention has been given to the design and synthesis of co‐crystals by both industry and academia because of its potential to change a molecule's physicochemical properties. Yet, difficulties arise when searching for adequate combinations of molecules (or coformers) to form co‐crystals…
Abstract A novel electrochemical biosensor was developed using a judiciously designed platform for the rapid and accurate determination of hydrogen peroxide (H2O2). The horseradish peroxidase (HRP) based biosensor was constructed by covalent anchoring of the enzyme to a newly synthesized quaternary ammonium‐based carb…
Dislocation defects induced by neutron irradiation can degrade the mechanical properties of reactor pressure vessel steel; although the properties can be restored by annealing, this treatment is energy- and time-intensive. A fast and energy-efficient method of decreasing the dislocation density is urgently needed. In…
Abstract Polarized‐light detection in solar‐blind ultraviolet region is indispensable for optoelectronic applications, whereas new 2D candidates targeted at solar‐blind UV range remain extremely scarce. 2D hybrid perovskite ferroelectrics that combine polarization and semiconducting properties are of increasing intere…
Designing highly efficient and low-cost electrocatalysts for oxygen evolution reaction is important for many renewable energy applications. In particular, strain engineering has been demonstrated as a powerful strategy to enhance the electrochemical performance of catalysts; however, the required complex catalyst prep…
Definitive treatment to achieve wound healing in major burns frequently include skin transplantation, where split-thickness skin grafts is considered gold standard. This method is associated with several drawbacks. To overcome these hurdles, efforts have been made to develop tissue engineered skin substitutes, often c…
Amplified spontaneous emission (ASE) threshold in CsPbBr3 quantum dot films is systematically reduced by introducing high quality TiO2 compact layer grown by atomic-layer deposition. Uniform and pinhole-free TiO2 films of thickness 10, 20 and 50 nm are used as a substrates for CsPbBr3 quantum dot films to enhance ampl…
Abstract BACKGROUND Pine oil contains a high percentage of polyunsaturated fatty acids, which make it prone to oxidation. Luteolin (LUT) micro‐nano particles with antioxidant properties can be used as stabilizers to form an edible oil‐in‐water Pickering emulsion to improve the oxidative stability of pine nut oil. RESU…
