Nitrate ammonification by Nautilia profundicola AmH: experimental evidence consistent with a free hydroxylamine intermediate.

Frontiers in Microbiology, 2013
The process of nitrate reduction via nitrite controls the fate and bioavailability of mineral nitrogen within ecosystems; i.e. whether it is retained as ammonium (ammonification) or lost as nitrous oxide or dinitrogen (denitrification). Here, we present

Research on the Detoxification of Municipal Solid Waste Incineration Fly Ash: Organic Acid Washing Pretreatment Coupled With Cement/DDTC Stabilization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.

Ambident Reactivity in the Phenyl + NO Radical Recombination

Chemistry – A European Journal, EarlyView.
ABSTRACT The recombination reaction of nitric oxide (NO) with radicals via its oxygen atom, rather than the more common nitrogen site, offers an intriguing pathway to the formation of oxynitrenes. The photochemical isomerization of nitroso compounds into their corresponding oxynitrenes may involve such a step.

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers

Chemistry – A European Journal, EarlyView.
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.
