Homoacetogenesis in Deep-Sea Chloroflexi, as Inferred by Single-Cell Genomics, Provides a Link to Reductive Dehalogenation in Terrestrial Dehalococcoidetes

mBio, 2017
The deep marine subsurface is one of the largest unexplored biospheres on Earth and is widely inhabited by members of the phylum Chloroflexi. In this report, we investigated genomes of single cells obtained from deep-sea sediments of the Peruvian Margin,

Microbially-mediated halogenation and dehalogenation cycling of organohalides in the ocean

Nature Communications
Microbially mediated organohalide cycling in the ocean has profound implications for global biogeochemical cycles and climate, but the geographic distribution and diversity of the halogenation-dehalogenation cycling microorganisms remain unknown.

Mass Production of Waste PVC‐Mediated Bamboo‐Derived Hard Carbon for Ultra‐Long Life Sodium Storage

Carbon Energy, EarlyView.
By a scalable PVC‐mediated bifunctional strategy, pre‐carbonized micrometer bamboo powder is converted into a functionally partitioned hard carbon anode with distinct domains. Featuring abundant internal closed pores and surface sp2‐enriched graphitic regions, this anode delivers exceptional high‐rate long‐cycle stability, retaining 93% capacity after ...

Light, Redox, and Ligand Noninnocence Cooperate in Naphthalene Diimide‐Functionalized N‐Heterocyclic Carbene Iridium Complexes

Chemistry – A European Journal, EarlyView.
Naphthalene diimide–N‐heterocyclic carbene iridium complexes display uncommon multistimuli‐responsive behavior combining strong Cl(lp)···π interactions, ligand non‐innocence, visible‐light photoreduction, and conPET photocatalysis. The study also provides new insight into the interaction of NDI platforms with fluoride/basic anions, revealing unexpected

A Naphthalene Monoimide Meisenheimer Complex as Strong Organic Hydride Donor for Metal‐Free CO2 Reduction

Chemistry – A European Journal, EarlyView.
A Meisenheimer complex derived from two‐fold reduction and protonation of naphthalene monoamide has been identified as a strong organic hydride donor which is able to reduce CO2. ABSTRACT Selective CO2 reduction to formate is challenging due to similar thermodynamics for the reaction to other products such as carbon monoxide and molecular hydrogen ...

Viologen-mediated reductive dehalogenation of α-halogeno ketones

, 2018
Various α-halogeno ketones undergo reductive dehalogenation to the corresponding ketones almost quantitatively with sodium dithionite using viologen as an electron-transfer catalyst in organic solvent-water two-phase ...

Adaptive Hydrogenation of Alkynes Using CO as a Molecular Trigger to Selectively Produce Alkanes or Z‐Alkenes

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
One catalyst for two products: CO acts as a molecular trigger for adaptive alkyne hydrogenation using supported Pd nanoparticles. The catalyst reversibly switches between the formation of alkanes under H2 and Z‐alkenes under H2/CO for 37 structurally diverse alkynes.

Dehalococcoides as a Potential Biomarker Evidence for Uncharacterized Organohalides in Environmental Samples

Frontiers in Microbiology, 2017
The massive production and improper disposal of organohalides resulted in worldwide contamination in soil and water. However, their environmental survey based on chromatographic methods was hindered by challenges in testing the extremely wide variety of ...

Influence of Substituents on Reductive Dehalogenation of 3-Chlorobenzoate Analogs [PDF]

Applied and Environmental Microbiology, 1991
The biochemical effects of aryl substituents on the reductive dechlorination of 3-chlorobenzoate analogs were quantified with (i) a stable 3-chlorobenzoate-grown methanogenic sludge enrichment, (ii) Desulfomonile tiedjei DCB-1, isolated from this enrichment and able to catalyze the reductive dechlorination of 3 ...
