Structure and properties of an inorganic perovskite Cs2SnI6 demonstrated its potential as a light-harvester or electron-hole transport material, however its optoelectronic properties are poorer than of lead-based perovskites. Here we report the way of light tuning of absorption and transport properties of cesium iodos…
Chiliadenus montanus is a medicinal plant that grows in Sinai Peninsula in Egypt. Phytochemical investigation of C. montanus methanolic extract led to the isolation of five methoxy flavonoids; Chrysosplenol-D (1), 5,7,4'-trihydroxy- 3,3'-dimethoxy flavone (2), 5,7-dihydroxy −3,3',4'-trimethoxyflavone (3), Bonanzin (4)…
Thanks to the nanogenerators known as state-of-the-art energy collecting devices, the mechanical energy in every environment can be converted into electrical energy. Some studies on the improvement of the performance of triboelectric and piezoelectric nanogenerators that convert mechanical energy to electrical energy…
Abstract A systematic investigation of the effects of different copper catalysts on the thermal behavior for ammonium dinitramide (ADN) was performed. ADN/copper catalyst mixtures were prepared in the ratio of 100/5 by grinding, and all samples were subjected to TG‐DSC studies using thermo‐gravimetric analysis coupled…
Bilayer Heisenberg ferromagnetic insulators hold degenerate terahertz Dirac magnon modes associated with two opposite valleys of the hexagonal Brillouin zone. We show that this energy degeneracy can be removed by breaking of the inversion symmetry ($\mathcal{I}$), leading to a topological magnon valley current. We sho…
This Letter presents a single-layer, dual-frequency unit for generating orbital angular momentum (OAM) in the microwave range. The unit cell consists of a square frame and two concentric rings with branches. The developed units can produce multifunctional OAM with required OAM mode, beam number, and direction. To demo…
Computer-aided synthesis has received much attention in recent years. It is a challenging topic in itself, due to the high dimensionality of chemical and reaction space. It becomes even more challenging when the aim is to suggest syntheses that can be performed in continuous flow. Though continuous flow offers many po…
The efficient storage method of hydrogen energy is a major concern in its practical application. Compared with other hydrogen storage methods, liquid hydrogen (LH 2 ) storage has the advantages of high energy storage density and low storage pressure. However, the temperature of LH 2 is significantly lower than room te…
Rare earth ions hosted in solids are good candidates for quantum technologies due to their chemical stability and optical and spin transitions exhibiting long coherence lifetimes. While bulk oxide crystals are usually the preferred host material, the development of a scalable silicon-compatible thin film platform woul…
Herein, two novel nonfullerene acceptors (NFAs), DTCC‐4Cl and DTSiC‐4Cl, are synthesized by end‐capping dithienocyclopentacarbazole (DTCC) and dithieno‐silolocarbazole (DTSiC) cores with chlorinated IC (2Cl‐IC) units, respectively. With the better‐known advantage of having the extraordinary σ*–π* conjugation of silole…
The application of infrared detectors based on epitaxially grown semiconductors such as HgCdTe, InSb and InGaAs is limited by their high cost and difficulty in raising operating temperature. The development of infrared detectors depends on cheaper materials with high carrier mobility, tunable spectral response and com…
Abstract Weight reduction plays an important role in reducing fuel and emissions, and the heat‐treatable 6016 aluminum alloy exhibits excellent application prospect in automobile lightweight. In this paper, ingot with constant Mg/Si ratio and decreased Mg and Si contents was obtained. Both the microstructure and the t…
The magnetic properties of newly prepared Tm 2 Ir 2 O 7 were investigated by means of magnetization and specific heat measurements and compared to the properties of other heavy rare-earth pyrochlore iridates. A bifurcation of zero-field-cooled and field-cooled magnetization coinciding with the onset of the specific he…
The polyvinylidene difluoride + barium titanate (BaTiO 3 ) +graphene composite (PBGC) is one of the widely explored thermoplastic matrix due to its 4D capabilities. The number of studies has been reported on the process parameters of twin-screw extruder (TSE) setup (as mechanical blending technique) for the developmen…
Abstract Reduced graphene oxide nanosheets were prepared by a modified hummer method and decorated with zinc nanoparticles to form nanocomposite (ZnO/RGO). The nanostructure surface materials of RGO with ZnO consist of different functional groups such as carboxyl, carbonyl, and hydroxyl groups, which facilitate the ox…

The bifunctional nonapeptide cannot only rely on the HWRGWV sequence as a site-oriented immobilizer to recognize the cryst…
Electrocatalytic water splitting via hydrogen evolution reaction (HER) represents one of promising strategies to gain hydrogen energy. In current work, self-supporting Co 0.85 Se nanosheets network anchored on Co plate (Co 0.85 Se NSs@Co) is fabricated by employing easily tailorable Co metal plate as the source conduc…
Layers of two-dimensional materials arranged at a twist angle with respect to each other lead to enlarged unit cells with potentially strongly altered band structures, offering a new arena for novel and engineered many-body ground states. For the exploration of these, renormalization group methods are an appropriate,…
A series of boron-doped (B-doped) catalysts with dissimilar mass ratios of boric acid and activated carbon (AC) were prepared by an impregnation method for acetylene acetoxylation. The introduction of a number of boron atoms activates the stable π electrons in AC, which not only enhances the electron transfer between…
