Metal‐Reduction‐Induced Dechlorination Coupling for Constructing All‐Inorganic Crosslinked Cyclotriphosphazene Networks With In Situ Metal Embedding

cMat, Volume 3, Issue 1, March 2026.
ABSTRACT The metal‐reduction‐induced dechlorination coupling (MR–DC) strategy enables the first successful synthesis of an all‐inorganic crosslinked phosphazene network (aPN) from hexachlorocyclotriphosphazene (HCCP) under mild reaction conditions. Using Cu as a model, the resulting Cu–aPN (copper‐embedded all‐inorganic phosphazene network) retains the

Mechanistic Origin of Photodegradation and Impurity Effects in Donor–Acceptor Luminescent Radicals

Advanced Optical Materials, Volume 14, Issue 7, 16 February 2026.
Purification‐dependent impurities distort the apparent optical and analytical data of TTM‐based radicals without altering their intrinsic photophysical properties. Carbazole attachment elevates the activation barrier of the photodegradation pathway, offering design principles for achieving more robust luminescent radical materials.

Temperature-associated effects on methanogenesis and microbial reductive dechlorination of trichloroethene in contaminated aquifer sediments

Frontiers in Water
BackgroundAquifer thermal energy storage (ATES) is a subsurface technology for urban heating and cooling. However, ATES systems may intersect with legacy groundwater contaminants from past anthropogenic activities.

Sabatier‐Adjusted d‐Band Centers of Scalable Asymmetric Iron Sites toward Dynamic Nonradical Network for Fast Mineralization with Low‐Amount Oxidant

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Asymmetric iron single‐atom catalysts with Sabatier‐adjusted d‐band centers overcome the inherent limitations of peroxymonosulfate (PMS) activation by establishing a synergistic nonradical pathway network, achieving exceptional pollutant mineralization (≈85%) at only one‐tenth conventional PMS dosage.

Enhancing methane production from food waste fermentate using biochar. The added value of electrochemical testing in pre-selecting the most effective type of biochar [PDF]

, 2017
Background: Recent studies have suggested that addition of electrically conductive biochar particles is an effective strategy to improve the methanogenic conversion of waste organic substrates, by promoting syntrophic associations between acetogenic and ...

Role of Electronically Conductive Scaffolds in Advancing Sodium‐Metal Chloride Battery Performance

Batteries &Supercaps, Volume 9, Issue 2, February 2026.
Sodium‐metal chloride batteries, where rock salt (NaCl) and metal powder provide capacity, offer promise for energy storage but face limits in specific energy. Integrating electronically conductive scaffolds into their positive electrode can enhance cycle life and metal utilization.

Effects of Ferric Oxyhydroxide on Anaerobic Microbial Dechlorination of Polychlorinated Biphenyls in Hudson and Grasse River Sediment Microcosms: Dechlorination Extent, Preferences, Ortho Removal, and Its Enhancement

Frontiers in Microbiology, 2018
Microbial reductive dechlorination of polychlorinated biphenyls (PCBs) has been observed in many PCB-impacted sediments. However, this biodegradation is relatively site-specific and can be affected by PCB compositions and sediment geochemical conditions.

Electroreductive Divergent Hydrogenations of Alkynes to Alkenes or Alkanes

ChemSusChem, Volume 19, Issue 3, February 2026.
An electrochemical system achieves divergent hydrogenations of alkynes to alkenes or alkanes without using molecular hydrogen. By adjusting electrochemical conditions, the reaction proceeds through nickel‐catalyzed proton transfer or NiH formation pathways, offering tunable chemoselectivity and broad functional‐group tolerance under mild conditions.
