Double Reduction of Ph3B to a Dianionic Borane With a Powerful SrI Intermediate
Angewandte Chemie, EarlyView.Although dianionic boranes follow the octet rule and are isoelectronic to carbanions or amines, the high electron density combined with the electropositive nature of the B center make them highly unstable species. In this study, we present synthesis and full characterization of a complex in which Ph3B2− is sandwiched between two Sr2+ ions and describe ...

Inadvertent Polychlorinated Biphenyls in Commercial Paint Pigments
Environmental Science and Technology, 2009 A polychlorinated biphenyl (PCB) that was not produced as part of the Aroclor mixtures banned in the 1980s was recently reported in air samples collected in Chicago, Philadelphia, the Arctic, and several sites around the Great Lakes.

Shear‐Mode Direct Piezoelectric Response of Ferroelectric Nematic Liquid Crystals
Advanced Science, EarlyView.Periodic shear‐induced electric current measurements are reported on two archetypic ferroelectric nematic liquid crystal compounds. From the temperature, frequency and shear angle dependent results of the first and second harmonic current signals together with temperature and oscillatory rheology measurements, the effective piezoelectric coupling ...

A Mild Disilane‐Enabled Halide‐to‐Deuterium Manifold With D2O for Aryl and Benzylic Halides
Angewandte Chemie, EarlyView.A broadly applicable Pd‐catalyzed dehalogenative deuteration enables efficient conversion of aryl and benzylic halides with inexpensive deuterium oxide (D2O). The method proceeds under exceptionally mild conditions without strong bases, harsh reductants, or stoichiometric Lewis acid halide scavengers, and tolerates a wide range of functional groups ...

Association between polychlorinated biphenyls and Parkinson’s disease neuropathology
Neurotoxicology, 2012 Polychlorinated biphenyls (PCBs) are synthetic chemicals primarily used as coolants and insulators in electrical equipment. Although banned for several decades, PCBs continue to exist in the environment because of their long half-life, continued presence

ATSDR toxzine : PBBs : polybrominated biphenyls [PDF]
Polybrominated biphenyls (PBBs) are chemicals that were added to plastics used in a variety of consumer products to make them difficult to burn.These products include items such as computer monitors, televisions, textiles, and plastic foams .

Advanced Science, EarlyView.Here, a PDL1 inhibitor is employed as a fifth component to modify lipid nanoparticles (LNPs). PDL1 inhibitor‐loaded LNPs show enhanced lymph node targeting, resulting in greater lymph node expansion, immune cell infiltration, and improved mRNA vaccine efficacy. This fifth component LNP could be a novel platform for mRNA vaccines.

Polychlorinated biphenyls – toxicity and risks
Croatian Journal of Food Science and Technology, 2012 Polychlorinated biphenyls (PCBs) are synthetic organochlorine compounds differing by their physico-chemical and toxicological properties and tend to bioaccumulate and biomagnificate in the environment and within the food chain.
