Nickel Foam Electrodes—A Versatile, Powerful, and Readily Available Tool in Electro‐Organic Synthesis

The Chemical Record, EarlyView.
Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

Integrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Carbon xerogel supported noble metal catalysts for fine chemical applications [PDF]

, 2008
Carbon xerogel, a mesoporous material, was produced by polycondensation of resorcinol and formaldehyde. A concentrated nitric acid solution was subsequently used to introduce high amounts of oxygenated groups on the surface.

The competitive interplay of 12‐oxophytodienoic acid (OPDA), protein thiols, and glutathione

The FEBS Journal, EarlyView.
12‐Oxophytodienoic acid (OPDA) is a phytohormone involved in plant growth and stress defense. Due to its cyclopentenone moiety, OPDA can form Michael adducts with thiol‐containing compounds such as glutathione and cysteine residues of proteins, resulting in alterations of the cellular redox regulatory network.

Observations of total RONO2 over the boreal forest: NO x sinks and HNO3 sources [PDF]

, 2013
In contrast with the textbook view of remote chemistry where HNO 3 formation is the primary sink of nitrogen oxides, recent theoretical analyses show that formation of RONO2 (ΣANs) from isoprene and other terpene precursors is the primary net chemical ...

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

The FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...
