Integrative Lattice and Surface Engineering of Nanoscale Fe<sup>0</sup> for Superior Dechlorination of Trichloroethene in Groundwater: Coordination in Reactivity, Selectivity, and Stability. [PDF]
Angew Chem Int Ed EnglA lattice and surface engineering strategy was employed to synthesize a novel core‐shell nanomaterial for superior reductive dechlorination of trichloroethene. In this design, FeNi serves as the core and FeS as the shell. Core composition and shell properties interactively determine materials’ performance, and the optimal material exhibited 242.7‐fold ...

Catalytic 1,2-Migratory Insertion in a Bismuth Redox Platform: Reductive Arylation of Aldehydes. [PDF]
Angew Chem Int Ed EnglWe report a multicomponent reaction involving an aryl halide, an aldehyde, and a silane derivative, facilitated by low‐valent bismuth redox catalysis under mild conditions. The protocol represents an unprecedented example of four elementary organometallic steps at a Bi center within the catalytic cycle.

Development of a Vinylated Cyclic Allene: A Fleeting Strained Diene for the Diels-Alder Reaction. [PDF]
Angew Chem Int Ed EnglA strain‐promoted Diels–Alder reaction of the vinylated cyclic allene, a highly reactive strained all‐carbon diene, was developed. Activation of the Kobayashi‐type precursor with fluoride ion generated the vinyl cyclic allene, which was trapped by dienophiles to produce decalin derivatives under mild conditions.

Acetylene-Fueled Trichloroethene Reductive Dechlorination in a Groundwater Enrichment Culture
mBio, 2021 Understanding the complex metabolisms of microbial communities in contaminated groundwaters is a challenge. PCE and TCE are among the most common groundwater contaminants in the United States that, when exposed to certain minerals, exhibit a unique ...

Intrinsic and bioaugmented aerobic trichloroethene degradation at seven sites
Heliyon, 2023 Trichloroethene (TCE) is one of the most prevalent contaminants in groundwater pollution worldwide. Aerobic-metabolic degradation of TCE has only recently been discovered at one field site. It has significant advantages over aerobic co-metabolism because

Detection of Organohalide-Respiring Enzyme Biomarkers at a Bioaugmented TCE-Contaminated Field Site
Frontiers in Microbiology, 2019 RNA-based biomarkers have been successfully detected at field sites undergoing in situ bioremediation, but the detection of expressed enzymes is a more direct way to prove activity for a particular biocatalytic process of interest since they provide ...

Nitrosative stress and nitrated proteins in trichloroethene-mediated autoimmunity. [PDF]
PLoS ONE, 2014 Exposure to trichloroethene (TCE), a ubiquitous environmental contaminant, has been linked to a variety of autoimmune diseases (ADs) including SLE, scleroderma and hepatitis. Mechanisms involved in the pathogenesis of ADs are largely unknown.
