We provide an exact study of dynamical correlations for the quantum spin-orbital liquid phases of an SU(2)-symmetric Kitaev honeycomb lattice model. We show that the spin dynamics in this Kugel-Khomskii type model is exactly the density-density correlation function of S=1 fermionic magnons, which could be probed in re…
The development of next-generation quaternary chalcogenides, such as $\mathrm{C}{\mathrm{u}}_{2}\mathrm{ZnSn}{\mathrm{S}}_{4}$ (CZTS) and $\mathrm{C}{\mathrm{u}}_{2}\mathrm{ZnGe}{\mathrm{S}}_{4}$ (CZGS), for solar energy and thermoelectric applications hinges upon both careful experimentation and accurate quantum mech…
Perovskite single-crystal (SC) or quasi-single-crystal (QSC) films are promising candidates for excellent performance of photoelectric devices. However, it is still a great challenge to fabricate large-area continuous SC or QSC films with proper thickness. Herein, we propose a pressure-assisted high-temperature solven…
This Minireview covers the latest developments of chemosensors based on transition-metal receptors and organic fluorophores with specific binding sites for the luminescent detection and recognition of iodide in aqueous media and real samples. In all selected examples within the last decade (made-post 2010), the iodide…
Abstract Carbon dioxide (CO2) conversion is an important yet challenging topic, which helps to address climate change challenge. Catalytic CO2 methanation is one of the methods to convert CO2, however, it is limited by kinetics. This work developed a structured Ni@NaA zeolite supported on silicon carbide (SiC) foam ca…
In recent years, there has been a rise in interest in the development of self-growing robotics inspired by the moving-by-growing paradigm of plants. In particular, climbing plants capitalize on their slender structures to successfully negotiate unstructured environments while employing a combination of two classes of…
The SiCp/6061Al composites with volume fractions of 10%, 20%, 30% and 40% were prepared by power metallurgy method. The effects of the volume fraction of SiCp on microstructure and mechanical properties were studied by means of phase analysis, microstructure observation, hardness test, friction test, wear and tensile…
Abstract A newly introduced Na−B bond in NaBH3−has been a challenge for the chemical bonding community. Here, a series of MBH3−(M=Li, Na, K) species and NaB(CN)3−are studied within the context of quantum chemical topology approaches. The analyses suggest that M–B interaction cannot be classified as an ordinary covalen…
Nanoscale optical vortices (OVs) carrying orbital angular momenta can be generated via photonic spin–orbit interaction (SOI) in nanostructures and have important applications in many emerging fields such as quantum communication and optical manipulations. Existing OV generators such as metasurfaces and chiral structur…
Series of activated carbons (ACs) have been prepared from Sugarcane bagasse powder by ZnCl2 activation at various impregnation ratios of ZnCl2 to Sugarcane bagasse powder of 0.25:1, 0.5:1, 1:1 and 2:1 by weight. Characteristics of the activated carbons (ACs) were determined by iodine number, methylene blue number, sur…
Oil shale is one of the alternative energies and fuel solutions in Jordan because of the scarcity of conventional sources, such as petroleum, coal, and gas. Oil from oil shale reservoirs can be produced commercially by pyrolysis technology. To optimize the process, mechanisms and rates of reactions need to be investig…
The present work aims to enhance the mechanical performance of monolithic Al alloy and single reinforced metal matrix composite using a hybridization technique. The microparticles of alumina and boron carbide were reinforced into cast Al alloy (6061) in a systematic varying ratio (i.e.100/0, 75/25, 50/50, 25/75 and 0/…
Photoinduced proton-coupled electron transfer (PCET) in anthracene-phenol-pyridine triads exhibits inverted region behavior, where the more thermodynamically favorable process is slower. The long-lived transient charge-separated state (CSS) associated with electron transfer from phenol to anthracene and inverted regio…
A new methacrylic boronate ester is synthesized and exploited to produce biocompatible nanoparticles with a boron-rich core by PISA.
A novel strain of an iron- and sulfur-oxidizing bacterium was isolated from a natural biotope at Kashen copper ore (Martakert Province, Republic of Artsakh). The strain is able to grow and oxidize ferrous ions in the range of pH 1.4-2.6 with optimal pH 2.0. The optimal temperature for growth is 35 °C. Acidithiobacillu…
Understanding the role of an electric field on the surface of a catalyst is crucial in tuning and promoting the catalytic activity of metals. Herein, we evaluate the oxidation of methane over a Pt surface with varying oxygen coverage using density functional theory. The latter is controlled by the electrode polarizati…
Abstract The development of practical multivalent-ion batteries critically depends on the identification of suitable positive electrode materials. To gain a better understanding of the intercalation chemistry of multivalent ions, model frameworks can be used to study the distinct specificities of possible multivalent…
Li-ion batteries play a vital role in electromechanical devices. The heat load on such batteries varies with time and application which falls as high temperature rise and it causes severe damages on a device and reduces the life cycle. It will be a big challenge in future decades of electronic devices and the electric…
A microbial fuel cell (MFC) is a promising renewable energy option, which enables the effective and sustainable harvesting of electrical power due to bacterial activity and, at the same time, can also treat wastewater and utilise organic wastes or renewable biomass. However, the practical implementation of MFCs is lim…
Taking inspiration from natural materials, composite materials can be reinforced by creating matrix architectures that can better accommodate and control internal stresses. Despite the recent success in the synthesis of artificial assemblies for local reinforcement through the introduction of oriented fibers and plate…
