In this study, the p-Cu2O/n-Cu2O homojunction film was prepared by a simple two-step electrodeposition method. The photoinduced charge transfer process in p-Cu2O/n-Cu2O homojunction film was studied using surface photovoltage technique. Then, the p-Cu2O/n-Cu2O homojunction film was assembled into a photoelectric...

Microcompartments are loose protein cages that encapsulate enzymes for particular bacterial metabolic pathways. These structures are thought to retain and perhaps concentrate pools of small, uncharged intermediates that would otherwise diffuse from the cell. In Salmonella enterica, a microcompartment encloses...

Orange mint moths, Pyrausta orphisalis (Walker) (Crambidae), were initially trapped in a study of noctuid moth attraction to floral volatiles. A subsequent series of trapping experiments in commercial mint fields determined that phenylacetaldehyde and 4-oxoisophorone were attractive to P. orphisalis...
