Enhanced transformation of sulfonamide antibiotics by manganese(IV) oxide in the presence of model humic constituents

Urs von Gunten, Jun Ma, Jin Jiang, Yang Song, Yang Zhou

In this study, a manganese(IV) oxide-mediator (MnO2-mediator) system for the abatement of sulfonamide antibiotics was evaluated. Two simple model humic constituents, syringaldehyde (SA) and acetosyringone (AS), could promote the transformation of sulfonami ...

Role of Cnot6l in maternal mRNA turnover

Jun Ma, Radek Jankele

Removal of poly(A) tail is an important mechanism controlling eukaryotic mRNA turnover. The major eukaryotic deadenylase complex CCR4-NOT contains two deadenylase components, CCR4 and CAF1, for which mammalian CCR4 is encoded by Cnot6 or Cnot6l paralogs. W ...

Uni-directional GaN-on-Si MOSHEMTs with high reverse-blocking voltage based on nanostructured Schottky drain

Elison de Nazareth Matioli, Jun Ma

In this work we present uni-directional GaN-on-Si MOSHEMTs with state-of-the-art reverse-blocking performance. We integrated tri-anode Schottky barrier diodes (SBDs) with slanted tri-gate field plates (FPs) as the drain electrode, and achieved a high rever ...

Nitrate formation during ozonation as a surrogate parameter for abatement of micropollutants and the N-nitrosodimethylamine (NDMA) formation potential

Urs von Gunten, Florian Frédéric Vincent Breider, Jun Ma, Yang Song

In this study, nitrate formation from ammonium and/or dissolved organic nitrogen (DON) was investigated as a novel surrogate parameter to evaluate the abatement of micropollutants during ozonation of synthetic waters containing natural organic matter (NOM) ...
