Reactions of hypobromous acid with dimethyl selenide, dimethyl diselenide and other organic selenium compounds: kinetics and product formation

Selenium (Se) is an essential micronutrient for many living organisms particularly due to its unique redox properties. We recently found that the sulfur (S) analog for dimethyl selenide (DMSe), i.e. dimethyl sulfide (DMS), reacts fast with the marine oxida ...

Z-REX uncovers a bifurcation in function of Keap1 paralogs

Yimon Aye, Xuyu Liu, Jesse Poganik, Yi Zhao, Alexandra Krina Van Hall-Beauvais, Kuan-Ting Huang

Studying electrophile signaling is marred by difficulties in parsing changes in pathway flux attributable to on-target, vis-& agrave;-vis off-target, modifications. By combining bolus dosing, knockdown, and Z- REX & mdash;a tool investigating on- target/on ...

Diformylxylose as a new polar aprotic solvent produced from renewable biomass

Jeremy Luterbacher, Anastasiia Komarova, Graham Reid Dick

Lignin is a promising candidate for the replacement of fossil-based materials, due to its natural abundance and aromatic structure. This same structure poses major challenges to lignin's exploitation for material development. The harsh conditions generally ...

The Synergism of DMSO and Diethyl Ether for Highly Reproducible and Efficient MA(0.5)FA(0.5)PbI(3)Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Hiroyuki Kanda, Tom Theodorus Antonius Lummen, Yi Zhang, Yonghui Lee, Keith Gregory Brooks, Ruiyuan Hu, Min Chen

Composition and film quality of perovskite are crucial for the further improvement of perovskite solar cells (PSCs), including efficiency, reproducibility, and stability. Here, it is demonstrated that by simply mixing 50% of formamidinium (FA(+)) into meth ...

Hypobromous Acid as an Unaccounted Sink for Marine Dimethyl Sulfide?

Urs von Gunten, Boris Droz

Marine emissions of dimethyl sulfide (DMS) to the atmosphere play a fundamental role in the global sulfur (5) cycle and have important consequences for the Earth's radiative balance. In the ocean, DMS is mainly produced by marine algae and bacteria via cle ...
