Based on the developed low-temperature step-by-step diffusion of impurity manganese atoms, magnetic nanoclusters atoms were formed in crystal lattice silicon with controllable concentration, specified and reproducible electrophysical parameters. With help electron spin resonance, it was proved experimentally that are p-Si<B,Mn> consist four positively charged which situated nearest equiva...

We report a novel design, based on a combination of lanthanide-doped upconversion nanoparticles and manganese dioxide nanosheets, for rapid, selective detection of glutathione in aqueous solutions and living cells. In this approach, manganese dioxide (MnO(2)) nanosheets formed on the surface of nanoparticles serve as an efficient quencher for upconverted luminescence. The luminescence can be tu...

For many years the late Dr. E. W. Smith, and following him Dr. D. P. Smith,47 used manganese dioxide in treating primary dysmenorrhea. Dr. A. L. Pierson"9 has also had success with this drug and has suggested a study of the subject. Long-standing dysmenorrhea, frequently so severe as to make the patient bed-fast for the first days of menstruation, has been completely relieved by the use of mang...

This study presents a novel procedure for accelerating methanogenesis from wastewater by adding elemental manganese into the anaerobic digestion system. The results indicated that elemental manganese effectively enhanced both the methane yield and the production rate. Compared to the control test without elemental manganese, the total methane yield and production rate with 4 g/L manganese addit...

The interaction of ligand-free manganese oxide nanoclusters with water is investigated, aiming at uncovering phenomena which could aid the design of artificial water-splitting molecular catalysts. Gas phase measurements in an ion trap in conjunction with first-principles calculations provide new mechanistic insight into the water splitting process mediated by bi- and tetra-nuclear singly charge...
