Pyrazine Revisited

Journal of Chemical Physics, 1986
Pyrazine is shown by its Molecular Eigenstate Spectra and by its quantum beats to be a small molecule. The effect of Coriolis coupling and non-resonant light scattering are discussed. This paper further treats the so-called "fast component". Its existence with a decay time of about 100 psec has by now been firmly established. It finds its cause in the "

Fermentation characteristics of four southern sichuan citrus cultivars

JSFA reports, EarlyView.
Abstract Background Sichuan, China's leading citrus‐producing region has strong potential for citrus wine development. Citrus is rich in bioactive compounds that enhance flavor and health value, yet current citrus wines often show weak aroma and bitterness.

Phenotypic, physicochemical, sensory, and functional attributes of cocoa (Theobroma cacao L.) from Brazilian Amazonian floodplain and upland ecosystems

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Cocoa (Theobroma cacao L.) from the Brazilian Amazon plays an important role in national production. While most cocoa is cultivated in upland systems, floodplain ecosystems represent a traditional and distinct production environment that may influence bean composition and quality.

Characterization of Structure, Properties, and Energetic Performance of a 1:1 Ammonium Dinitramide‐3,4‐Diaminofurazan Cocrystal

Propellants, Explosives, Pyrotechnics, EarlyView.
Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Crystal Engineering of Chelating Hybrid Ultramicroporous Materials via Pillar Modulation for Energy‐Efficient Acetylene Separation

Small, EarlyView.
A new chelating hybrid ultramicroporous material platform is developed using anion modulation to fine‐tune pore chemistry and binding environments, enabling selective C2H2 capture over CO2. One of them, NbOFFIVE‐enmepy‐Zn, exhibits multiple binding interactions for C2H2 vs.

Molecular structures and in Silico molecular docking of new pyrazine-based heterocycles as antibacterial agents

BMC Chemistry
Compound 2-(2-cyanoacetamido)pyrazine (3) serves as a key precursor for synthesizing various new pyrazine-linked heterocycles, including pyridine, thiazole, pyrazole, chromene, and pyrazolotriazine derivatives.

Targeting protein–protein interactions with reversible covalent modalities: Non‐cysteine chemistries

British Journal of Pharmacology, EarlyView.
Abstract Protein–protein interactions (PPIs) are central to diverse cellular functions, and represent a rapidly expanding class of therapeutic targets. Advancements in covalent drug design have enabled small‐molecule drugs to overcome challenges associated with engaging these targets, such as limited durations of action and difficult‐to‐drug (expansive,

Highly Efficient Mechanochromic Thermally Activated Delayed Fluorescence in the Deep Red to Near‐Infrared in Copper(I) [2.2]Isoindolinophanyl‐Carbene Carbazolates

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Electrophilic [2.2]isoindolinophanyl‐based carbene iPC has been employed as charge‐transfer acceptor ligand in a series of [Cu(iPC)(carbazolate)], which show mechanochromism and environment‐dependent luminescence due to intermolecular C─‐H‐π interactions.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

Ecological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
