Unraveling Alkali Ion Electron Donation for Enhancing Heterogeneous Catalytic Oxidation

open access: yesAdvanced Science, EarlyView.
A new mechanistic pathway for potassium (K) ions as electron donors is identified by constructing single K ion chains confined within hexagonal WO3 tunnels. The as‐produced high‐electron‐density Kδ+ (0<δ<1) ions not only facilitate the formation of oxygen vacancies that behave classical electronic effect but, more importantly, also directly donate ...

A case study on the γ-octalactone induced expression of Obp83g-2 in Bactrocera dorsalis (Hendel) revealed the transcriptional regulation of insect odorant binding protein

open access: yesCommunications Biology
As crucial components of the insect olfactory system, odorant binding proteins (OBPs) are involved in detecting environmental chemical cues. Expression alterations of OBPs induced by odorants are conserved in many species.

Transition‐Metal‐Free Zeolite Composites for Tandem Catalytic Conversion of Methane to Light Olefins

open access: yesAdvanced Science, EarlyView.
Light olefins can be produced from methane using a cascade catalytic system that combines transition‐metal‐free (FER zeolite with an acidic zeolite, such as SAPO‐34, under relatively mild conditions. In this tandem process, methane is first oxidized to methanol over the FER zeolite and then converted to olefins via the MTO reaction on the acidic ...

Osmotically Tunable Microdroplets Enable Amplification‐Free CRISPR Detection of Gene Doping

open access: yesAdvanced Science, EarlyView.
A novel amplification‐free clustered regularly interspaced short palindromic repeats/CRISPR‐associated protein (CRISPR/Cas) 12a assay is integrated with osmotically shrinkable double emulsion droplets for the rapid and ultrasensitive detection of gene doping.

The role of pest control operators in vertebrate pest control

open access: yes, 1964
The status of the pest control industry is described, along with comments on those private pest control operators who conduct control of vertebrate pests. The economics of pest control businesses are considered. Results of a survey of rodenticides most often used by pest control operators are reported.
