Insect herbivores contend with various plant traits that are presumed to function as feeding deterrents. Paradoxically, some specialist insect herbivores might beneWt from some of these plant traits, for example by sequestering plant chemical defenses that herbivores then use as their own defense against natural enemies. Larvae of the butterXy species Battus philenor (L.) (Papilionidae) sequest...

one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...

Epoxy resins are used widely as protective coatings, in a wide range of harsh chemical environments. This work explores the influence subtle structural variation both epoxy and amine monomers upon performance cured networks, whether changing molecular geometry, nature chemistry, or mass between cross-linking reactive groups. To achieve this, four industrially relevant (two based on bisphenol A—...
