Conspectus Atomically size-selected gold (Au) clusters protected by organic ligands or stabilized by polymers provide an ideal platform to test fundamental concepts and size-specific phenomena, such as the superatomic concept and metal-to-nonmetal transition. Recent studies revealed that these stabilized Au clusters t…
The inherent susceptibility of low-dimensional materials to thermal fluctuations has long been expected to pose a major challenge to achieve intrinsic long-range ferromagnetic order in two-dimensional materials. The recent explosion of interest in atomically thin materials and their assembly into van der Waals heteros…
We find that the recently developed self-consistent and appropriately normed meta-generalized gradient approximation, which has been found to provide highly accurate results for many materials, is, however, not able to describe the stability and properties of phases of Fe important for steel. This is due to an overest…
Transition metal dichalcogenides (TMDs) have attracted much attention due to their promising optical, electronic, magnetic, and catalytic properties. Engineering the defects in TMDs represents an effective way to achieve novel functionalities and superior performance of TMDs devices. However, it remains a significant…
Over recent years, research on the structures and properties of ligand-protected gold cluster molecules has gained significant interest. The crystal structure information accumulated to date has revealed the structural preference to adopt closed polyhedral geometries, but the use of multidentate ligands sometimes lead…
Abstract Low cost, controlled crystallinity, chemical, and mechanical stability enable application of polymers in energy, water, electronics, and biomedical industries. Recent studies have shown that tailoring surface properties of polymers impacts their durability and functionality in these applications. However, the…
Abstract Palladium diselenide (PdSe 2 ), a thus far scarcely studied group‐10 transition metal dichalcogenide has exhibited promising potential in future optoelectronic and electronic devices due to unique structures and electrical properties. Here, the controllable synthesis of wafer‐scale and homogeneous 2D PdSe 2 f…
Thermoelectrics, in particular solid-state conversion of heat to electricity, is expected to be a key energy harvesting technology to power ubiquitous sensors and wearable devices in the future. A comprehensive review is given on the principles and advances in the development of thermoelectric materials suitable for e…
Most recently, silver nanoparticles due to antibacterial properties have been considered in medical science. So the aim of the study was green synthesis of silver nanoparticles using Berberis vulgaris leaf and root aqueous extract and its antibacterial activity. After collection, identification and extraction of Berbe…
As leading candidates of sheet steels for advanced nuclear reactors, three types of Ni–Mo–Cr high-strength low alloy (HSLA) steels named as CNST1, CNST2 and CNSS3 were irradiated by 400 keV Fe+ with peak fluence to 1.4 × 1014, 3.5 × 1014 and 7.0 × 1014 ions/cm2, respectively. The distribution and morphology of the def…
Appropriate mixtures of Sm 2 O 3 and SeO 2 with various chloride fluxes yielded single crystals of Sm 3 O 2 Sm[SeO 3 ] 4 (monoclinic, P 2 1 / n; a = 1497.89(8), b = 556.61(3), c = 1639.63(9) pm, β = 91.054(3)° with Z = 8 for Sm 2 Se 2 O 7 ) or Sm 3 O 2 Cl[SeO 3 ] 2 (orthorhombic, Pnma; a = 565.82(4), b = 1457.14(9), c…
The performance of a thermodynamic cycle for the calculation of the standard reduction potential (SRP) of a series of metals is examined. It is found that the introduction of simple entropic corrections substantially improves the agreement with experimental data. The accuracy of the estimations is in the range of 0.04…
Photon mass attenuation coefficients and effective atomic numbers for three types of concretes containing pumice mineral in different rates (namely 0%, 50% and 100%) were studied by photon transmission experiments, by simulations and by theoretical calculations. Experimental procedure was realized by using a 3ʺ×3ʺ NaI…
During a survey of freshwater diatoms from Shibadukeng stream in the Xianju County, Zhejiang Province, China, a new gomphonemoid species, Gomphonema bicepiformis sp. nov. has been recorded. The new species is diagnosed from all others in the genus based on morphology as observed with both light and scanning electron m…
Cationic gelatin nanoparticles ((+)nGNPs) were prepared by in situ polymerization upon the surfaces of monodispersed gelatin nanoparticles (GNPs) using N-(3-Aminopropyl)methacrylamide (APm) as monomer, which were then decorated with doxorubicin terminated poly(2-methylacryloyloxyethyl phosphorylcholine) (DOX-pMPC) via…
Graphite under high magnetic field exhibits consecutive metal-insulator (MI) transitions as well as reentrant insulator-metal (IM) transitions in the quasiquantum limit at low temperature. In this paper, we identify the low-$T$ insulating phases as excitonic insulators with spin nematic orderings. We first point out t…
Abstract Two‐dimensional materials have allowed for great advances in the biosensors field and to obtain sophisticated, smart, and miniaturized devices. In this work, we optimized a highly sensitive and selective phenol biosensor using 2D pnictogens (phosphorene, arsenene, antimonene, and bismuthene) as sensing platfo…
We studied the mineralogical properties and chemical composition of different granites using energy dispersive X-ray spectroscopy coupled with scanning electron microscopy to understand the relationship between granite signatures and soil characteristics, including weathering patterns and soil fertility status. The di…
Abstract A green chemistry approach was successfully fabricated in this work to synthesize γ‐MnOOH nanorods under mild conditions, in which oxygen was used as the green oxidizer and no surfactants or templates were involved. Only the oxygen was bubbled through the solutions of divalent manganese in the presence of NaO…
Abstract Monodisperse silica particles (SiPs) were surface‐modified with a newly designed silane coupling agent comprising a triethoxysilane and an alkyl halide, namely, 6‐(triethoxysilyl)hexyl 2‐bromopropionate, which was further treated with potassium O ‐ethyl dithiocarbonate (PEX) to immobilize xanthate molecules o…
