Lethal effects of insecticides on adults of Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae)

Entomological Communications, 2022
The predator Eriopis connexa (Germar, 1824) (Coleoptera: Coccinelidae), is an important biological control agent in wheat fields. In this work, we evaluated the lethal effects of fifteen insecticides used in the wheat crop on adults of the predator E ...

Isotopic and spin selectivity of H_2 adsorbed in bundles of carbon nanotubes

, 2002
Due to its large surface area and strongly attractive potential, a bundle of carbon nanotubes is an ideal substrate material for gas storage. In addition, adsorption in nanotubes can be exploited in order to separate the components of a mixture.

UNBINDING OF SURFACE DEFECTS UNDER THE DEFECT-SELECTIVE ADSORPTION

Condensed Matter Physics, 2003
Unbinding of surface topological defects in the presence of the defect-selective adsorption is investigated using a coupled Coulomb Gas - Lattice Gas model. The unbinding temperature increases with the increasing selectivity (and coverage) for both, sign-

Simulation study of a rectifying bipolar ion channel: Detailed model versus reduced model

Condensed Matter Physics, 2016
We study a rectifying mutant of the OmpF porin ion channel using both all-atom and reduced models. The mutant was created by Miedema et al. [Nano Lett., 2007, 7, 2886] on the basis of the NP semiconductor diode, in which an NP junction is formed.

A pendant proton shuttle on [Fe4N(CO)12]- alters product selectivity in formate vs. H2 production via the hydride [H-Fe4N(CO)12]. [PDF]

, 2016
Proton relays are known to increase reaction rates for H2 evolution and lower overpotentials in electrocatalytic reactions. In this report we describe two electrocatalysts, [Fe4N(CO)11(PPh3)]- (1-) which has no proton relay, and hydroxyl-containing [Fe4N(
