Aerobic biodegradation of biphenyl and polychlorinated biphenyls by Arctic soil microorganisms [PDF]
Applied and Environmental Microbiology, 1997 We examined the degradation of biphenyl and the commercial polychlorinated biphenyl (PCB) mixture Aroclor 1221 by indigenous Arctic soil microorganisms to assess both the response of the soil microflora to PCB pollution and the potential of the microflora for bioremediation.

Advanced Science, EarlyView.A single‐molecule cascade supramolecular system comprising L/D‐FPy, CB[8], and SC4AD serves as an efficient light‐harvesting platform. It facilitates cascade energy transfer and chiral transfer to acceptor dyes. Co‐assembly with a PVA matrix produces a multicolor solid film that exhibits enhanced luminescence dissymmetry factors (glum), enabling ...

Iron‐Photocatalyzed C(sp3)–H Phosphonylation of Alkanes
Angewandte Chemie, EarlyView.Alkyl phosphonates are valuable motifs that can be prepared by phosphonylations of various common functional groups. However, direct phosphonylations of C(sp3)–H bonds are limited to activated positions. Herein, we report an iron‐photocatalyzed phosphonylation of unactivated C(sp3)–H bonds using a novel phosphite radical trap, which is equipped with an

POLYBROMINATED DIPHENYL ETHERS (PBDEs) AND POLYCHLORINATED BIPHENYLS (PCBs) IN HOUSEHOLD DUST IN BIRMINGHAM, UK. [PDF]
Polychlorinated biphenyls (PCBs) are persistent organic pollutants that were used primarily as insulating fluids in electrical equipment and were banned in the 1970s, even so they are still being found in humans.

Carboxyphenolate Coordination Frameworks for High‐Voltage Calcium Storage
Advanced Science, EarlyView.A hexaanionic carboxyphenolate coordination framework, Ca2‐M‐THBPD (M = Mg, Ca, Ba), exhibits ligand‐centered enolate‐quinonoid redox activity enabling tunable, high‐voltage Ca2+ storage (3.5 V vs Ca2+/Ca) modulated by spectator cations. The amorphous structure accommodates reversible divalent‐ion insertion, contributing to enhanced cycling stability ...

Advanced Science, EarlyView.The effect of the structural arrangement of DIO and its analogs on ferroelectric phases is explored. Consequently, it is found that an asymmetrically fluorinated phenyl 4‐biphenylcaroboxylate skeleton is one of the favorable structural motifs for the emergence of enantiotropic ferroelectric liquid crystal phases.

Brutalist Structures – Polychlorinated Biphenyls
, 2021 Until they were banned by the Federal Government in 1978, Polychlorinated Biphenyls or PCBs, were used extensively as sealants in Brutalist structures across the United States.
