The solid solutions of chlorapatite compounds Ba5Mn3 xVxO12Cl (x 1⁄4 0e3.0) and Ba5Mn3 xPxO12Cl (x 1⁄4 0 e3.0) have been synthesized through solid state reactions and Pechini or solegel method using citric acid. The colors of the samples change from white (x 1⁄4 3.0) through turquoise (x 1⁄4 1.5) to dark green (x 1⁄4 0) with increasing amount of manganese. Optical measurements reveal that the o...

Manganese-deficient individuals have decreased manganese elimination. This observation has prompted suggestions that relative manganese deficiency may increase the risk for manganese neurotoxicity following inhalation exposure. The objective of this study was to determine whether dietary manganese intake influences the pharmacokinetics of inhaled manganese tetroxide (Mn3O4). Postnatal day (PND)...

White-rot fungi (WRF) are ubiquitous in nature with their natural ability to compete and survive. WRF are the only organisms known to have the ability to degrade and mineralize recalcitrant plant polymer lignin. Their potential to degrade second most abundant carbon reserve material lignin on the earth make them important link in global carbon cycle. WRF degrade lignin by its unique ligninolyti...

Redox-inactive metals are found in biological and heterogeneous water oxidation catalysts, but, at present, their roles in catalysis are not well understood. Here, we report a series of high-oxidation-state tetranuclear-dioxido clusters comprising three manganese centres and a redox-inactive metal (M). Crystallographic studies show an unprecedented Mn3M(µ4-O)(µ2-O) core that remains intact on c...

Two new Mn(III) complexes with unprecedented topologies containing the tert-butylphosphonate ligand (t-BuPO3(2-)), [Mn9O6(t-BuPO3)2(O2CMe)11 (MeCOOH)(H2O)].8H2O(1), and [NBu(n)4][Mn13O6(t-BuPO3)10(OH)2(N3)6(MeCOOH)2(H2O)2].6H2O(2) have been prepared by treatment of Mn(O2CMe)2 and NBu(n)4MnO4 with tert-butylphosphonic acid in the presence of different bases. The core of 1 consists of two [Mn3O] ...

Hydrotalcite-like compounds has layered structure and unique properties. Rich surface hydroxyl groups interlayer anions make it have excellent heavy metal adsorption capacity. The variable valence manganese element in the laminate gives good catalytic performance. This paper introduces concept, structure, preparation methods application of hydrotalcite-like detail, order to provide reference fo...

To clarify whether manganese nutritional status is better reflected by the manganese concentration in lymphocytes or in whole blood, we injected manganese solutions intravenously into manganese-deficient rats and determined manganese concentrations in lymphocytes, whole blood, and various tissues. The manganese concentrations in lymphocytes and tissues, but not in whole blood, were significantl...
