Circadian rhythms in insecticide susceptibility, metabolic enzyme activity, and gene expression in Cimex lectularius (Hemiptera: Cimicidae). [PDF]
, 2019 Many insect species display daily variation of sensitivity to insecticides when they are exposed to the same concentration at different times during the day. To date, this has not been investigated in bed bugs.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

European Journal of Organic Chemistry, EarlyView.The total synthesis of the manzamine alkaloid keramamine C (2) in its racemic form was achieved in 5 steps, with ring‐closing metathesis as the key step. The metathesis is strongly improved by an intramolecular H‐bond‐induced conformational fixation of the amide bond, inducing close proximity of the terminal double bonds in the precursor molecule.
