BACKGROUND Mineral based preparations are widely used for centuries as antimicrobial agents. However, the efficacy and the mode of action of mineral based preparations are uncertain due to the insufficient antimicrobial studies. Arogyawardhana Vati (AV) and Manikya Rasa (MR) are such two Rasashastra herbo-minerallic drugs commonly in India and other countries in South Asia. Despite of their wel...

The Na(+), K(+), and inorganic phosphate levels of the plasma and sartorius muscle of the toad Bufo marinus were determined. Soaking in normal Ringer brought about the usual cation shifts, but did not alter the level of inorganic phosphate in the cell. Increases in the external phosphate level brought about an increase in the internal phosphate, but the apparent phosphate space of muscle is som...

We describe how supramolecular assembly, mediated by control of the ratio of the hetero-atoms in the units [Mo2S2O2] 2+ and SeO3 2 leads to the formation of new types of building blocks, [(Mo2O2S2)3(OH)4(H2O)6(SeO3)] 1⁄4 {Mo6} and [(Mo2O2S2)2(OH)2(H2O)4(SeO3)] 1⁄4 {Mo4} which are linked in an type of inorganic ‘panelling’ to the assembly of a range of new clusters 1–3 with the general formula {...

Phase segregation in aqueous biphasic systems (ABS) composed of four hydrophilic ionic liquids (ILs): 1-butyl-3-methylimidazolium methylsulfate and 1-ethyl-3-methylimidazolium methylsulfate (C(n)C₁im C₁SO₄, n = 2 and 4), tributylmethyl phosphonium methylsulfate (P₄₄₄₁ C₁SO₄) and methylpyridinium methylsulfate (C₁Py C₁SO₄) and two high charge density potassium inorganic salts (K₂CO₃ and K₂HPO₄) ...

Crystals of two new inorganic uranyl silicates, Cs[(UO6)2(UO2)9(Si2O7)F] (1) and Rb2[(PtO4)(UO2)5(Si2O7)] (2), were produced from melts in evacuated silica tubes. Their structures have been solved by direct methods: 1 is trigonal, P-31c, a = 10.2040(3), c 17.1278(5) Å, V 1544.45(10) Å3, R1 0.042; 2 tetragonal, P4/mbm, 16.0400(24), 3.9231(6) 1009.34(10) 0.045. the first example cation–cation int...

Zero‐dimensional (0D) hybrid metal halides, which consist of organic cations and isolated inorganic halide anions, have emerged as phosphors with efficient broadband emissions. However, these materials generally too wide bandgaps thus cannot be excited by blue light, hinders their applications for white light‐emitting diodes (WLEDs). The key to achieving a blue‐light‐excitable 0D phosphor is re...

Two-dimensional (2D) hybrid perovskites with the Ruddlesden-Popper lattice (A′)2(A)n−1MnX3n+1 are emerging as promising optoelectronic candidates, both inorganic and organic ingredients of which can be tailored to modulate physical properties. Nevertheless, there is a scarcity 2D multilayered motifs A-site large-size cations occupying perovskite cavities. Here, by rational mixed-cation alloying...
