In this work we compare the hydrothermal stability performance of a Templated Molecular Sieve Silica (TMSS) membrane against a standard, non-templated Molecular Sieve Silica (MSS) membrane. The tests were carried under dry and wet (steam) conditions and characterised using pure gases (He, H2, CO and CO2) at 1-2 atm membrane pressure drop at 200°C. Single gas TMSS membrane H2, permeance and H2/C...

Electrodialysis, reverse electrodialysis, and related electrochemical processes are increasingly important technologies for water purification renewable energy generation storage. The electrical efficiency of these is directly to the permselectivity ion exchange membranes (IEMs) – defined as extent which membrane permits passage counter-ions (ions opposite charge membrane, e.g., cations a catio...

This work is focused on the study of possible changes in the electrochemical transport parameters of cellulose membranes due to the effect of ionising radiation. A cellophane membrane (membrane C5) was irradiated with a dose of 80 Gy (membrane Ir80) and differences in the electrochemical parameters for pristine and irradiated samples are studied. Salt permeability, ion transport number, permsel...

Persistent hyperglycemia, as occurring in diabetes, induces changes in circulating as well as in structural proteins. These changes involve substitution of lysine residues by glucose adducts resulting in early Amadori products that evolve into toxic and active substances, the advanced glycation end adducts. In previous studies, we demonstrated that early glycated (Amadori) albumin infused into ...

Physiol. 227(6) : 1436-1443. 1974.-Theophylline and choleragen reduced the electrical conductance of the in vitro rabbit ileum SOc/, and 25yi, respectively, increased the potential difference and caused only a relatively short-lived increase in short-circuit current. The increase in shortci...
