A pain-causing and paralytic ant venom glycopeptide
Summary: Ants (Hymenoptera: Formicidae) are familiar inhabitants of most terrestrial environments. Although we are aware of the ability of many species to sting, knowledge of ant venom chemistry remains limited.

Aqueous Equilibria: Acids, Bases, and Solubility. A General Chemistry Laboratory Experiment [PDF]
We refer to two major types of general chemistry freshman laboratory experiments: discovery and cookbook. The typical Freshman enrolled in general chemistry has the skills to perform an experiment that is somewhere between cookbook and discovery, and we ...

Symmetry breaking by quantum coherence in single electron attachment [PDF]
Quantum coherence-induced effects in atomic and molecular systems are the basis of several proposals for laser-based control of chemical reactions. So far, these rely on coherent photon beams inducing coherent reaction pathways that may interfere with ...

Gas hydrates in sustainable chemistry.
Gas hydrates have received considerable attention due to their important role in flow assurance for the oil and gas industry, their extensive natural occurrence on Earth and extraterrestrial planets, and their significant applications in sustainable ...

On-surface light-induced generation of higher acenes and elucidation of their open-shell character
The synthesis of large acenes via traditional solution-chemistry routes is hindered by their poor solubility and high reactivity under ambient conditions.

Redox driven B12-ligand switch drives CarH photoresponse
CarH is a coenzyme B12-dependent photoreceptor involved in regulating carotenoid biosynthesis. How light-triggered cleavage of the B12 Co-C bond culminates in CarH tetramer dissociation to initiate transcription remains unclear. Here, a series of crystal

Controlling Chemical Reactions in Confined Environments: Water Dissociation in MOF-74
The confined porous environment of metal organic frameworks (MOFs) is an attractive system for studying reaction mechanisms. Compared to flat oxide surfaces, MOFs have the key advantage that they exhibit a well-defined structure and present significantly

Isomerization as a Key Path to Molecular Products in the Gas-Phase Decomposition of Halons [PDF]
The decomposition of halons remains controversial concerning the branching between radical and molecular products. The latter channel, where it has been found, is presumed to occur via a constrained symmetric multicenter transition state.

Current estimates of K1* and K2* appear inconsistent with measured CO2 system parameters in cold oceanic regions [PDF]
Seawater absorption of anthropogenic atmospheric carbon dioxide (CO2) has led to a range of changes in carbonate chemistry, collectively referred to as ocean acidification.
