Herein, the design and experimental characterization of γ ‐In 2 Se 3 /CuO interfaces are considered. Thin films of γ ‐In 2 Se 3 are coated with thin layers of CuO at room temperature. The heterojunction device is structurally, morphologically, and optically characterized. It is observed that the coating of CuO onto γ…
In organic light emitting diodes (OLEDs), all triplet excitons can be harvested as light via reverse intersystem crossing (RISC) based on thermally activated delayed fluorescence (TADF) emitters. To realize efficient TADF, RISC should be fast. Thus, to accomplish rapid RISC, in the present study, a novel TADF emitter,…
The Nano-ZrO2 reinforced AZ31 alloy composites were fabricated by friction stir processing (FSP) with three multi-pass and high rotation speed. The AZ31/2.14 vol% ZrO2, AZ31/4.29 vol% ZrO2 and AZ31/6.43 vol% ZrO2 composites were designed. The fine microstructure and uniform dispersion of ZrO2 particles were observed i…
Abstract Intrinsic defects and Mo‐related defects in vanadium carbide VC, as well as the defect complexes between vacancies and Mo defects were investigated by means of first‐principles calculations within the framework of density functional theory. In addition, Mo diffusion in VC was also studied using LST/QST method…
High Resolution Image Download MS PowerPoint Slide A charge-transfer (CT) interaction between 1,3,5-trinitro-2,4-dimethylbenzene (TNX) and anionic phosphate is evaluated, yielding a high band electronic transfer interaction that can be observed as a distinct color change when phosphate is present in solution. The indu…
Abstract Oxide-based photoelectrodes recently have been at the forefront of research for photoelectrochemical water splitting. While most oxide-based photoanodes suffer from severe electron–hole recombination, BiVO4 photoanodes are known to achieve exceptionally high electron–hole separation efficiencies. However, an…
We propose a topological nodal-ring superconductor (TNRSC) by inducing superconductivity on a topological nodal-ring semimetal (NRSM). Such a TNRSC can map to a one-dimensional BDI class topological superconductor and host both ${N}_{\mathrm{BDI}}=1$ and 2 topological phases in the Brillouin zone. These two topologica…
The article discusses dynamic requirements for designing ground manipulator platforms that can be utilized to verify the performance of controllers developed for space manipulators. Dimensional analysis is used to formalize the dynamic equivalence conditions and control scaling laws between a given space manipulator a…
Abstract With a growing pipeline of major transport infrastructure projects transforming Victoria's road and rail networks, there is an increase in demand for the construction of underground tunnels using the shield tunneling method. Such tunnels need to be designed for fire resistance in order to preserve both struct…
Motility in archaea is facilitated by a unique structure termed the archaellum. N -Glycosylation of the major structural proteins (archaellins) is important for their subsequent incorporation into the archaellum filament. The identity of some of these N -glycans has been determined, but archaea exhibit extensive varia…
The integration of thermal energy storage systems (TES) in waste-heat recovery applications shows great potential for energy efficiency improvement. In this study, a 2D mathematical model is formulated to analyze the performance of a two-tank thermochemical heat storage system using metal hydrides pair (Mg2Ni/LaNi5),…
High-Mn twinning-induced plasticity (TWIP) steels have been proposed to meet higher passenger safety and crash-safe vehicle frame requirements demanded by the automotive industry. The corrosion behaviour of welded Fe–30Mn–5Al–0.5C–6Cr TWIP steel using the resistance-spot-welding (RSW) technique was studied. Welds show…
Direct (hetero)arylation (DHA) is playing a key role in improving the efficiency and atom economy of C–C cross coupling reactions, so has impacts in pharmaceutical and materials chemistry. Current research focuses on further improving the generality, efficiency and selectivity of the method through careful tuning of t…
Acetyl coenzyme A (Ac-CoA)-dependent N-acetylation is performed by arylalkylamine N-acetyltransferase (AANAT) and is important in many biofunctions. AANAT catalyzes N-acetylation through an ordered sequential mechanism in which cofactor (Ac-CoA) binds first, with substrate binding afterward. No ternary structure conta…
To resolve the inherent trade-off issue between responsivity and detectivity in FA 0.9 Cs 0.1 PbI 3 perovskite photodetectors, this paper proposes a novel strategy using multifunctional self-combustion additives (urea and ammonium nitrate). During the early stages of crystallization, urea allows for the formation of a…

On-surface Ullmann-type reactions are widely used to fabricate various carbon nanostructures in a bottom-up approach by conjugating small hydrocarbons via dehalogenation. In the reaction, the dissociated halogen atoms remain on the substrate and are usually removed by high-temperature annealing. Here, we demonstrate a…
With desirable physical performances of impressive actuation strain, high energy density, high degree of electromechanical coupling and high mechanical compliance, dielectric elastomer actuators (DEAs) are widely employed to actuate the soft robots. However, there are many challenges to establish the dynamic models fo…
An anapole state that breaks inversion and time reversal symmetries with preserving translation symmetry of underlying lattice has aroused great interest as a new quantum state, but only a few candidate materials have been reported. Recently, in a spin-orbit coupled Mott insulator \SIR, the emergence of a possible hid…
In the present work, nanocomposites based on the partially silane-terminated polyurethanes reinforced with sulfuric acid-treated halloysite nanotubes were synthesized and evaluated as a potential candidate for transparent blast resistant configurations. The polyurethane must present high tensile ductility at high stra…
