Many Zintl phases exhibiting a CrB type structure form hydrides. Systematic studies of AeTtHx (Ae = Ca, Sr, Ba; Tt = Si, Ge, Sn), LnTtHx (Ln = La, Nd; Tt = Si, Ge, Sn), and LnGaHx (Ln = Nd, Gd) showed the vast structural diversity of these systems. Hydrogenation reactions on REGa (RE = Y, La, Tm) and RESi (RE = Y, Er,…
Abstract The interface between the oxide insulators LaAlO 3 and SrTiO 3 (LAO/STO) hosts a two-dimensional electron gas. The combination of interfacial conductivity and superconductivity at ultra-low temperatures with the physical phenomena of the oxide parent materials has fueled extensive research in the field since…
MgFe2O4, ZnO and MgFe2O4-ZnO samples were successfully prepared through low temperature solution combustion route. The structural and morphological investigation were accomplished by PXRD, HRSEM, UV-visible and FTIR. The PXRD results point towards the reduced size of synthesized nanocomposites, which was further confi…
Herein, exfoliated, multilayered molybdenum disulfide (MoS 2 ) (m‐MoS 2 ) field‐effect transistors (FETs) are implemented with bilayered SiN x /SiO x gate dielectrics on indium tin oxide (ITO) substrates. For a quantitative understanding on gas adsorption effects on the electrical performance of m‐MoS 2 FETs, subgap d…
The dehydrogenation of low-carbon alkane to obtain olefins is an effective way to meet the steadily increasing demand of these building blocks in chemical industry. In this study, Ca-doped CrOx/γ-Al2O3 catalysts were fabricated via a one-pot method by employing Cr(OH)3 as the precursor, and their catalytic performance…
Herein, multiwavelength Raman spectroscopy studies of graphene samples synthesized directly on SiO 2 and Si(100) substrates by microwave plasma‐enhanced chemical vapor deposition (MW PECVD), using five different excitation wavelengths in ultraviolet (UV), visible light, and near‐infrared (NIR) ranges, are presented pa…
Abstract To recycle a multicomponent siliceous solid waste (MSW), a by‐product of the zeolite industry, as a K‐feldspar substitute for the preparation of medium temperature calcium matte glazes, the chemical composition, phase evolution, and thermal behavior of the waste versus temperature were characterized using mul…
We report micro-Raman spectroscopy, high-resolution scanning electron microscopy (HR-SEM) and atomic force microscopy (AFM) investigation of changes in chemical vapor deposition grown single-layer graphene structure induced by extreme ultraviolet (EUV) irradiation. We found that the exposures at doses up to 200 mJ/cm…
We prepared titanyl phthalocyanine (TiOPc) monolayers on sapphire-prism supported Au{111} substrates through solution deposition and characterized their photoresponses using a custom-built laser-assisted scanning tunneling microscope under ambient conditions. Two types of lattice structures (hexagonal and rectangular)…
Gladkovskyite (IMA2018-098), MnTlAs 3 S 6 , is a new sulfosalt from the Vorontsovskoe gold deposit, Sverdlovsk Oblast', Northern Urals, Russia. The new mineral occurs in limestone breccias cemented by abundant realgar, orpiment, baryte and pyrite, as well as minor clinochlore, fluorapatite, quartz and talc. Gladkovsky…
The controllable incorporation of the dopant element with strictly designed coordination geometry into the target host merits untold scientific and technological potential, yet it has been met with limited success in a disordered matrix. Here, we present a general route for precisely tuning the coordination geometry o…
ZrCx ceramics with different stoichiometries were irradiated under a four MeV Au ion beam in doses of 2 × 1016 ions/cm2 at room temperature, corresponding to ~130 dpa. Grazing incidence, X-ray diffraction and transmission electron microscopy were performed to study the radiation damage and microstructure evolution in…
The influence of poly(acrylonitrile–butadiene–styrene) (ABS) as a special β-nucleating agent on the impact and tensile properties of isotactic polypropylene (iPP) were investigated by dynamic rheological measurements, wide-angle X-ray diffraction (WAXD), differential scanning calorimetry (DSC), scanning electron micro…
The synthesis, characterisation and homogeneous catalytic oxidation results of two manganese(III) porphyrins of the so-called second-generation of metalloporphyrin catalysts, containing one or four 3,5-dichloropyridyl substituents at the meso positions are reported for the first time. The catalytic efficiency of these…
The optical and electronic properties of π-conjugated polymers in organic electronic devices depend on their intra- and interchain interactions, dictated by the internal arrangement of the polymer chains in an amorphous or semicrystalline aggregated state. Here, we discuss the utility of circular intensity differentia…
Recently, the metalens has been investigated for its application in many fields due to its advantages of being much smaller than a conventional lens and is compatible with nano-devices. Although metalenses have extraordinary optical performance, it is still not enough in some occasions such as wavefront detection for…
Abstract This paper investigates the crystallization behavior of a Ge 2 Sb 2 Se 4 Te 1 (GSST) chalcogenide phase change material film using Raman spectroscopy. The properties of as‐deposited, thermally treated, and laser‐written GSST films are investigated. A single mask exposure laser excitation process was developed…
Abstract Composition‐structure‐property (C‐S‐P) approach, named as “glass structural gene modeling (GSgM), for glass database development and new glass design are detailed in this article. C‐S‐P modeling principle and modeling procedure are selectively demonstrated using two sets of phosphate glass systems with variou…
A small bandgap and light carrier effective mass ( m 0 ) lead to obvious ambipolar transport behavior in carbon nanotube (CNT) field-effect transistors (FETs), including a high off-state current and severe degradation of the subthreshold swing (SS) with increasing drain bias voltage. We demonstrate a drain-engineered…
The present survey reports on the colloidal stability of aqueous dispersions of nitrogen-rich carbon nanodots (N-CDs). The N-CDs were synthesized by thermally induced decomposition of organic precursors and present an inner core constituted of a β − C 3 N 4 crystalline structure surrounded by a surface shell containin…
