Calcium sulfide particles in mixtures with carbon particles, as in coal gasifier waste, are converted to calcium oxide by repeated cycles of oxidation and reduction by utilizing the carbon as a source of the reducing gas required for the treatment. The treatment can be conducted in a two zone ...
Conversely, studies in A549 cells detect a negligible reduction in viability after 0.5 ppm formaldehyde exposure for 72 h using the ALI, and in BEAS-2B cells show over 90% viability over a period of 6 h with exposure concentrations up to 15 ppm42,89. The latter observation, also based on...
The genome contents were further analyzed in terms of sulfur metabolism. Consistent with our hypothesis proposed in the Introduction, diverse sulfur reduction or oxidation pathways were identified. The presence ofsat(K00958) andcys(K00860, K00390, K00380, and K00381) genes suggested the capacity...
7A). Meanwhile, Western blotting analysis also showed that AOPP treatment triggered a reduction in nuclear β-catenin expression at 30 min and 15 min in HL-7702 cells and AML-12 cells, respectively (Fig. 7B). In the cytoplasmic fraction, the decrease in β-catenin expression took place at ...
A small cathodic current was observed in the reverse scan at ~0 V, presumably due to the reduction of the Au oxide. When both 1-phenylethanol and KOH were present, three characteristic oxidation waves (A–C) were observed (Fig. 2d). Peak A was the first oxidation peak observed during ...
Moreover, NCOA7's oxidation resistance function requires expression of only its carboxyl-terminal domain and is similar in this regard to OXR1. We find that, in human cells, NCOA7 is constitutively expressed and is not induced by oxidative stress and appears to localize to the nucleus ...
N-NO2− ions were possibly formed through the EO of ammonia on the anode (Equation (9)) or electrochemical reduction of nitrate on the cathode (Equation (10)) [63]. However, oxidation of amine groups present in organic compounds needs to be taken into consideration during NO2− ...
(6) were shown to be good choices for the hydrogen peroxide (H2O2, oxidant) and ferrous sulphate heptahydrate (FeSO4•7H2O, catalyst supplier) dosage, in terms of COD, total suspended solids (TSS), and fecal coliforms (FC) reduction in the real wastewater treated by the advanced Fenton ...
(oxidation of ammonium to nitrite), nitrite-oxidizing bacteria (NOB) (oxidation of nitrite to nitrate), and/or complete ammonium oxidizer (Comammox) (complete oxidation of ammonium to nitrate), and denitrifiers (reduction of nitrate via nitrite and intermediate gaseous nitrogen oxide products to ...
Addition of p-toluenesulfonamide (PTS or TsNH2; 2.0 x 10-3 –8.0 x 10-3 mol dm-3), the reduction product of CAT, retards the rate of the reaction in both cases (Table 2). Further, log-log plots of k / vs [PTS] were linear (R2> 0.9994) with negatives slopes of 0.36 and ...
