Oberflächencharakterisierung auf atomarer Ebene: Vom Sehen einzelner Atome zum Verständnis chemischer Prozesse

Physik in unserer Zeit, EarlyView.
Sehen ist der erste Schritt in Richtung Verstehen. Dieses Prinzip gilt von der Beobachtung ferner Galaxien bis hin zur Untersuchung einzelner Atome und hält damit über viele Größenordnungen. Heutzutage ermöglichen moderne Mikroskope die Beobachtung einzelner Atome und sogar die gezielte Kontrolle chemischer Reaktionen einzelner Moleküle ...

Performance evaluation of a scent transfer unit for sampling of explosives and their residues to investigate nuisance alerts

Journal of Forensic Sciences, EarlyView.
Abstract Volatile organic compounds associated with explosives such as Composition C‐4 serve as important targets for canine training as well as field analysis. In parallel, 1‐bromooctane (1‐BO) is a benchmark to contextualize canine performance and aid interpretation of results.

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

Insect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

Volatile Compounds in Feathers of the Scarlet Macaw (Ara macao) Reflect Sex and Pair‐Bond Status

Integrative Zoology, EarlyView.
Scarlet macaws exhibit sex‐ and pair‐related differences in plumage volatile composition, with males showing greater chemical richness. Partnered individuals differ in specific compound classes, whereas no clear association with immune function was detected. These results support a potential role for olfactory cues in sexual and social communication in
