PORES IN WATER CONDUCTING CELLS OF PLANTS Steven Jansen Ulm University This gure shows a transverse section of wood tissue from Hibiscus syriacus observed with a transmission electron microscope. One of the secrets behind water transport under negative pressure, which plants are able to do e ort...
Poly-4-vinylpyridinebisulfate (P4VPBS) is a polymeric salt that has shown promise as a water-free proton-conducting material (solid electrolyte) suitable for use in membrane/electrode assemblies in fuel cells. Heretofore, proton-conducting membranes in fuel cells have been made from perfluorinated io...
(n = 1) while electron transfer from the fundamental excitonic level is prevented at basic pH, due to the high energy difference between such an excitonic level and the valence band, situating the excitonic level below the LUMO of BCP; and (b) energy-band diagram of OPV solar cells based...
LiCoO2/(PPy:CMC) cells also exhibited an initial spike in potential followed by a descent in the first charging step. A number of processes could lead to this behavior including slow electrolyte infiltration or doping of PPy by the electrolyte. While the study of this phenomenon lies outside ...

aanodic and the cathodic reactions for the fuel cells do tend to differ. In both the alkaline and the acidic fuel cells, the electrolyte’s conducting species are protons and hydroxide ions—the products of water’s electrolytic dissociation. 正极和负极反应为燃料电池倾向于不同。 在碱性和酸性燃料...
capacitors [13,14], solar cells [7,15,16] and transistors [17,18] due to its exceptional advantages of high electrical conductivity (s), excellent electrochemical and environmental stability, unique processibility, good biocompatibility, superior film-forming properties, and fine tuning of thei...

Among the thirteen types of water channel proteins, aquaporins (AQPs), which play various essential roles in human physiology, AQP4 is richly expressed in cells of the central nervous system and implicated in pathological conditions such as brain edema. Therefore, researchers have been looking for ...
