inorganic membrane

An inorganic proton exchange membrane based on sintered mesoporous silica and phosphoric acid was developed with a high proton conductivity of 0.06 S cm(-1) at 200 °C, achieving an excellent power output of 689 mW cm(-2) in H2 at 190 °C and 200 mW cm(-2) in methanol at 200 °C with no external humidification.

Study of receptor mediated selective anion transmembrane transport using parallel artificial membrane permeability assay.

Journal: :The Analyst 2013

Lenka Veverková Kamil Záruba Vladimír Král

The separation performance of inorganic anions ReO4(-), Br(-), SO4(2-), and NO3(-) using porphyrin-alkaloid quaternary salt transporters is examined using parallel artificial membrane permeability assay. Active and selective transport of perrhenate is achieved by porphyrin-brucine conjugates. Herein, chlorides are used as antiporters and complete removal of perrhenates from a source solution is...

The effect of freezing on thylakoid membranes in the presence of organic acids.

Journal: :Plant physiology 1971

K A Santarius

The effect of salts of organic acids on washed and non-washed chloroplast membranes during freezing was investigated. Thylakoids were isolated from spinach leaves (Spinacia oleracea L.) and, prior to freezing, salts of various organic acids or inorganic salts or both were added. Freezing occurred for 3 to 4 hours at -25 C. After thawing membrane integrity was investigated by measuring the activ...
