Surfactants are a class of compounds that reduce the surface tension of a liquid. They can be adsorbed on gas-liquid or liquid-liquid interfaces, thus changing the properties of the interface and affecting its stability, wettability, viscosity, surface potential, etc.
Layer-structured group III chalcogenides are highly anisotropic and attractive materials for stable photocathodes and battery electrodes. In this work, the vapor phase growth of high-quality monolayer GaSe nanosheets with multiple shapes and sizes is achieved by tuning the Ga/GaSe ratio in the precursor. A theoretical model based on density functional theory calculations and kinetic Wulff construction theory describes the observed shape evolution of the GaSe nanosheets. Results show that the Ga/
What is GaSe?GaSe has been used as a semiconductor and a far-infrared conversion material at 14-31 THz and above. GaSe also finds applications in highly-efficient solar cells and battery technology. GaSe is a non-linear optical material with great potential in non-linear optical devices and THz generation. Recently, two-dimensional (2D) GaSe materials have drawn the increasing attention of researchers because of their superior performance in optical and electrical aspects. Hu et al. Reported a p
What is Aluminium magnesium boride?AlMgB14 ceramics were reported as high-hardness materials over a decade ago. While different synthesis routes for processing AlMgB14 ceramics were reported in the past, the synthesis routes are still not optimized and present a significant challenge to the manufacturers. This work explored six different synthesis routes for the synthesis of AlMgB14 powder. The synthesized compositions were characterized by XRD, where weight fractions of each phase were calculat
Experimental and QM studies agree that the B4C crystal structure has rhombohedral symmetry with the R3̅m space group. The unit cell of B4C contains one 12-atom icosahedron located at the apexes of the primitive cell with one 3-atom linear chain aligned along the [111]r direction. Each icosahedron involves two crystallographic sites: six polar sites (p) connecting directly to other icosahedra and six equatorial sites (denoted as e) connecting with the 3-atom chains. The B4C structure was original
The structure of aluminum boride is similar to that of intermetallic compounds, and its structure mainly depends on the crystal structure of aluminum metal and boron rather than their valence relationship. Aluminum borides are AlB2, AlB4, and AlB12. The diboride AlB2 can be formed by reacting two elemental substances above 600°C. It is a layered structure in which Al atoms directly overlap (A, A mode), and B atoms are filled in the triangular column formed by the direct overlap of Al atoms; that

Generally, the voltage depends on the manganese oxidation state and the MnO2 structure type (1–5 V). Using host structures such as carbon, lithium alloys, and metal oxides instead of metallic lithium as the negative electrode improved battery safety, especially for rechargeable cells. Several rechargeable lithium battery systems with manganese oxide positive electrodes were commercialized in the past: C/LiMn2O4 (3.5 V), LiAl/MnO2 (2.5-V, coin cell), and LiTiO2/LiMn2O4 (1.5-V coin cell). Layered
What is manganese dioxide?The type of manganese dioxide (MnO2) and its quantity used in dry cells are mainly responsible for cell capacity. Performance characteristics depend on individual crystal structure, varying degrees of hydration, and the activity of the manganese dioxide. Manganese dioxide potentials are additionally affected by the pH of the electrolyte. Most zinc–carbon batteries are cathode limited. Four different types of manganese dioxide are applied in dry cells: (NMD alpha- and be
The structure and phase composition of colloidal SPM Fe3O4 NPs remains puzzling despite the availability of increasing amounts of structural information. Various spectroscopic measurements have shown that the structure of SPM Fe3O4 NPs can be described as a magnetite core with a thin overoxidized (Fe3+) surface shell, which is compositionally close to a maghemite polymorph (γ-Fe2O3).9a, Conversely, the putative Fe3O4@γ-Fe2O3 core−shell structure has not been observed by X-ray diffraction or elec
Comprising a packed array of neighboring cubes, the Fe2+ ions occupy half of the octahedral sites, with Fe3+ cations being split evenly across the unoccupied octahedral and tetrahedral sites. Fe3O4 samples are non-stoichiometric, where the temperature-dependent ferromagnetism originates from the coupling of spins of Fe2+ and Fe3+ electrons in the octahedral sites. Therefore, the octahedral and tetrahedral sites induce the magnetic field, giving it permanent magnetism. Synthetic and natural magne
The recently released data from the Ministry of Economy, Trade, and Industry of Japan shows that in 2019, Japan's domestic sales of lubricants will decline. Still, both imports and exports will increase, and production will also increase. In
What is Calcium hexaboride?Calcium hexaboride (CaB6) is a compound of calcium and boron in which the coordination number of the calcium is 18. Calcium hexaboride is also referred to as calcium boride. It is an important material due to its large electrical conductivity, moderate hardness, high chemical stability, and high melting point.
