A palladium composite membrane was prepared via electroless plating technique using organic-inorganic method during activation process. The ceramic support surface was modified by two TiO2-boehmite and one γ-alumina layers to avoid Pd penetration in support pores. Thin and defect-free Pd composite membrane was obtained by creating a relative smoothness on the ceramic support and using Pd nanopa...

Isolated, atomically thin conducting membranes of graphite, called graphene, have recently been the subject of intense research with the hope that practical applications in fields ranging from electronics to energy science will emerge1. Here, we show that when immersed in ionic solution, a layer of graphene becomes a new electrochemical structure we call a trans-electrode. The transelectrode's ...

outer surface, similar protrusion inwards might be expected with isolated walls, whereas a difference in the gel structure of the wall could explain the morphological difference, and also the finding (Burger, 1966) that isolated walls bind little more antibody than do whole bacteria. The inacessibility of new teichoic acid to concanavalin A at the bacterial surface shows that the teichoic acid ...

In this work, the effects of operative parameters on CH4, CO2, O2, and N2 membrane gas separation for poly (4-methyl-1-pentane) (PMP) membrane modified by adding nanoparticles of TiO2, ZnO, and Al2O3 are assessed and investigated. The operative parameters were type and percentage of nanoparticles, and cross membrane pr...

Chemically altered hemoglobin-based oxygen carriers have been developed as prototype blood substitutes. Such molecules may affect numerous biological processes, since free hemoglobin scavenges nitric oxide (NO). Diaspirin cross-linked hemoglobin (DCLHb) is a chemically cross-linked molecule, which has a pressor effect on blood pressure, mainly mediated by NO scavenging. However, the effects of ...

The performance stability and regeneration property of catalytic membranes should be considered from a practical viewpoint. In this review, recent works concerning issue have been comprehensively summarized. was first summarized in terms the two commonly employed evaluation ways, i.e., multi-cycle experiments long-time filtration. main deactivation reasons included adsorption pollutants its oxi...

Micropollutants (MPs) are widely occurring in surface water all over the world with extremely low concentrations, and their treatment requires high energy consumption efficiency. In this study, a large-sized planar photocatalytic reactive ceramic membrane (PRCM) was prepared using facile dip-coating method nitrogen-doped TiO2 (N-TiO2-CM) for purification of tetracycline hydrochloride (TC) as mo...

purpose : to investigate the effects of mtp-131 on trabeculum cells cultured under hydrostatic pressure methods : glaucomatous human trabecular meshwork (gtm3) cells were divided into three groups: the mtp-131 group, the hydrostatic group, and the normal group. the mtp-131 group was pretreated with 1 µm mtp-131, and the cells were then cultured under 80 mmhg pressure for 24 hours. the normal gr...
