Electrocatalysis by nanoparticles: Oxidation of formic acid at manganese oxide nanorods-modified Pt planar and nanohole-arrays

open access: yesJournal of Advanced Research, 2010
The electro-oxidation of formic acid (an essential reaction in direct formic acid fuel cells) is a challenging process because of the deactivation of anodes by the adsorption of the poisoning intermediate carbon monoxide (CO).

A Novel H2O2 Generator for Tumor Chemotherapy-Enhanced CO Gas Therapy

open access: yesFrontiers in Oncology, 2021
Carbon monoxide (CO) gas therapy is a promising cancer treatment. However, gas delivery to the tumor site remains problematic. Proper tunable control of CO release in tumors is crucial to increasing the efficiency of CO treatment and reducing the risk of

Natural organic matter in sedimentary basins and its relation to arsenic in anoxic ground water: the example of West Bengal and its worldwide implications [PDF]

open access: yes, 2004
In order to investigate the mechanism of As release to anoxic ground water in alluvial aquifers, the authors sampled ground waters from 3 piezometer nests, 79 shallow (80 m) wells, in an area 750 m by 450 m, just north of Barasat, near Kolkata (Calcutta),

Manganese toxicity with ephedrone abuse manifesting as parkinsonism: a case report

open access: yesJournal of Medical Case Reports, 2012
Introduction Neurologic consequences of manganese toxicity have been recognized since 1837. A new form of presumed manganese poisoning has been reported in drug-addicted persons from Eastern Europe and the Baltic states who have intravenously injected ...

A DFT study on adsorption behaviors of NH3 and SO2 on MnCe/TiNTs catalyst

open access: yesChemical Physics Impact, 2022
Manganese-cerium catalyst has attracted much attention due to its extraordinarily good low-temperature performance for detrinification technology, but its poor SO2 resistance limits its wide application.

The effect of Nb2O5 and ZrO2 additions on the behaviour of Li/MgO and Li/Na/MgO catalysts for the oxidative coupling of methane [PDF]

open access: yes, 1991
Incorporation of Nb2O5 or ZrO2 into both Li/MgO and Li/Na/MgO systems produced ternary and quaternary catalysts, respectively, capable of attaining optimal C2 yields and selectivities at lower temperatures relative to the unpromoted materials. The degree

Corrosion behaviour of nitrided ferritic stainless steels for use in solid oxide fuel cell devices

open access: yes, 2020
Plasma nitriding was applied to ferritic stainless steel substrates to improve their performances as interconnects for solid oxide fuel cell devices. The samples underwent electrical conductivity test and SEM/EDS, TEM/EDS, environmental-SEM analyses. The

Beneficial effect of Mentha spicata essential oil on lead and manganese induced nephrotoxicity and oxidative damage in rat kidney

open access: yesNotulae Scientia Biologicae, 2020
Our work focused on the impact of chronic lead acetate and manganese chloride poisoning on renal function in Wistar rats. It also tested the efficacy of the essential oil extracted from (Mentha spicata) spearmint in reversing these effects by treating ...

Essential trace (Zn, Cu, Mn) and toxic (Cd, Pb, Cr) elements in the liver of birds from Eastern Poland [PDF]

open access: yes, 2012
We have focused our study on the concentrations of essential heavy metals (Zn, Cu and Mn) and non-essential trace metals (Pb, Cd and Cr) in the livers of birds from Eastern Poland. The largest mean amount of Zn - as much as 279 mg/kg dry mass (d.m.) -
