Gas diffusion electrodes (GDE) obtained by sputtering metal films on polytetrafluoroethylene (PTFE) membranes are among the most performant used to electrochemically reduce CO2. The present work reveals several essential aspects for fabricating PTFE-based gas (GDEs) CO2 electroreduction (CO2R). We show that adding an additive layer (a mixture of carbon and Nafion™ or only) is required stabilizi...

Dipeptidyl peptidase IV (DPPIV) is a membrane glycoprotein with a type II orientation in the plasma membrane. As shown in a cell-free translation system, the amino-terminal 34 amino acids of rat DPPIV are involved in translocating nascent polypeptide across the membrane of microsomes and in anchoring the translocated polypeptide in the microsomal membrane. The amino-terminal sequence performing...

To understand the function of membrane proteins, the knowledge of their structure, especially the knowledge of the position of transmembrane segments (TMSs) and of their membrane topology (i.e., orientation of TMSs across the membrane), is crucial. Since most TMSs of α-type polytopic (i.e., having multiple TMSs) membrane proteins are composed of hydrophobic amino acids, they are usually detecte...

Inorganic-organic composite electrolyte membranes were fabricated from CsXH3-XPMo12O40 (CsPOMo) and quaternary diazabicyclo-octane polysulfone (QDPSU) using a polytetrafluoroethylene (PTFE) porous matrix for the application of intermediate temperature fuel cells. The CsPOMo/QDPSU/PTFE composite membrane was made proton conducting by using a relatively low phosphoric acid loading, which benefits...
