23 Coal mine drainage (CMD) is the single greatest threat to the environment of Appalachia 24 in the United States, releasing large volumes of acid and metal contaminants (e.g., Mn, Fe). 25 Passive limestone-based treatment systems are the most cost-effective method for manganese(II) 26 removal from CMD. The success of passive Mn(II)-removal systems has been variable due to a 27 poor understand...

Fully epitaxial magnetic tunnel junctions (MTJs) with Co-based Heusler alloy Co(2)MnSi electrodes and a MgO tunnel barrier were fabricated with various values of Mn composition α for Co(2)Mn(α)Si in Co(2)Mn(α)Si/MgO/Co(2)Mn(α)Si MTJs. The tunnel magnetoresistance (TMR) ratios at both 4.2 K and room temperature (RT) increased systematically with increasing α in Co(2)Mn(α)Si electrodes from Mn-de...

AIMS/INTRODUCTION To elucidate the clinical significance of median neuropathy at the wrist (MN) in patients with diabetes. MATERIALS AND METHODS In total, 340 patients with diabetes who were hospitalized for glycemic control were enrolled in the present study. The diagnoses of MN and diabetic polyneuropathy (DPN) were based on electrophysiological criteria. A total of 187 patients were divide...

Exposure to excessive levels of manganese (Mn) is associated with the development of movement disorders, with symptoms overlapping with Parkinson's disease. Oxidative damage has been implicated as a key contributor to Mn-induced neurotoxicity. We have recently reported that divalent Mn (Mn(2+)) stimulates brain microglia to produce and release hydrogen peroxide (H2O2), and microglial-free radic...

This paper presents the reinforcement of nanocellulose (NC) in polyvinyl alcohol (PVA) to examine effect amount on properties PVA. The was successfully extracted by sulfuric acid hydrolysis method and ultrasonication, successively reinforced with solvent-casting method. After incorporating into PVA matrix, tensile strength, elongation at break, water absorption capacity, transmittance, thermal ...

A library of 10 Mn-containing complexes capable of switching reversibly between the Mn(II) and Mn(III) oxidation states was prepared and evaluated for potential usage as MRI reporters of tissue redox activity. We synthesized N-(2-hydroxybenzyl)-N,N',N'-ethylenediaminetriacetic acid (HBET) and N-(2-hydroxybenzyl-N,N',N'-trans-1,2-cyclohexylenediaminetriacetic acid (CyHBET) ligands functionalized...

In this combined X-ray diffraction and photoluminescence study, the coordination environment of Mn(2+) and the photoluminescence of single Mn(2+) doped KMgBO3 phosphors were studied. Mn(2+) occupies Mg(2+) sites, which were coordinated by six O(2-). The strong absorption of KMgBO3:Mn(2+) was ascribed to the strong relaxation of spin and parity forbidden d-d transitions of Mn(2+). The emission b...

Activation of a water molecule by the electrochemical oxidation of a Mn-aquo complex accompanied by the loss of protons is reported. The sequential (2 × 1 electron/1 proton) and direct (2 electron/2 proton) proton-coupled electrochemical oxidation of a non-porphyrinic six-coordinated Mn(II)OH2 complex into a mononuclear Mn(O) complex is described. The intermediate Mn(III)OH2 and Mn(III)OH compl...
