Ecology and evolution of pyrazines in insects

Biological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Characterization of Key Odorants in Jimo Huangjiu Using a Characteristic Aroma-Directed Screening Strategy

Foods
Jimo Huangjiu (JMHJ), a Chinese geographical indication product from Shandong Province, is characterized by distinctive burnt-like and smoky aromas. However, the specific odorants responsible for these sensory attributes remain uncharacterized.

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

Chemistry – A European Journal, EarlyView.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

High‐Energy‐Density Redox Flow Batteries: Mechanisms, Design Strategies, and Recent Progress

Chemistry – A European Journal, EarlyView.
ABSTRACT The inherent intermittency of energy sources such as solar and wind power hinders the transition to renewable energy, necessitating advanced energy storage solutions. Enhancing energy density is crucial for lowering system costs and enabling large‐scale deployment.

Modular Rh‐Catalyzed Synthesis and Biological Profiling of Diverse Pentafluorobenzenesulfonamide Reactive Fragments

Chemistry – A European Journal, EarlyView.
A modular Rh‐catalyzed synthetic approach enabled the preparation of diverse reactive fragments from available substrates. The reactive fragments modified Aurora A kinase via several distinct modification reaction classes. In a complex biological environment, the constellation of modified proteins depended critically on the reactive fragment structure.

GC–MS analysis of alkylpyrazines in the pyrolysis oils of silica-polyethylenimine CO2 sorbents

Journal of Chromatography Open
Solid sorbents based on silica and polyethyleneimine (PEI) are intensively investigated in the field of carbon capture and storage (CCS). Pyrolysis was proposed as a thermal process to recover the pure silica from exhausted sorbents and convert PEI into ...

Reversible I2 Uptake Induces Record‐High Spin‐Crossover Hysteresis in a Fe(II) Hofmann‐Type MOF

Chemistry – A European Journal, EarlyView.
Reversible iodine uptake in a flexible Fe(II) Hofmann‐type MOF [Fe(pz)Pd(CN)4] induces record‐wide SCO hysteresis. Gas‐phase I2 acts as internal chemical pressure, stabilizing both high‐spin and LS states without altering the framework, providing a general strategy for tunable bistability in coordination networks.
