2D PVSCs with “favorable” ion accumulation are realized via thermal–light post-treatment, which increases the built-in potential and device performance.

Aspergillus oryzae, Penicillium citrinum and Rhizopus stolonifer isolated from Taif soil, Saudi Arabia could survive in a liquid medium containing up to 500 !lglml Zn. Aspergillus oryzae and Penicillium citrinum were more tolerant to zinc toxicity than Rhizopus stolonifer. The resistance and accumulation of zinc in the tested fungi were discussed according to tolerance index and zinc uptake in ...

Data-dependent external m/z selection and accumulation of ions is demonstrated in use with ESI-FTICR instrumentation, with two different methods for ion selection being explored. One method uses RF/DC quadrupole filtering and is described in use with an 11.5 tesla (T) FTICR instrument, while the second method employs RF-only resonance dipolar excitation selection and is described in use with a ...

In mammalian neurons, the precise accumulation of sodium channels at the axonal initial segment (AIS) ensures action potential initiation. This accumulation precedes the immobilization of membrane proteins and lipids by a diffusion barrier at the AIS. Using single-particle tracking, we measured the mobility of a chimeric ion channel bearing the ankyrin-binding motif of the Nav1.2 sodium channel...

Fungal elicitor stimulates a multicomponent defense response in cultured parsley cells (Petroselinum crispum). Early elements of this receptor-mediated response are ion fluxes across the plasma membrane and the production of reactive oxygen species (ROS), sequentially followed by defense gene activation and phytoalexin accumulation. Omission of Ca2+ from the culture medium or inhibition of elic...

Following excision, etiolated epicotyl segments of Pisum sativum L. cv. Alaska exhibit a marked hyperpolarization of membrane potential which is followed by a linear accumulation of K(+) when segments are incubated in Higinbotham nutrient solution. Segments aged for several hours and then reexcised display only a slight depolarization of membrane potential and no delay in ion accumulation; thus...
