The control of local order in polymer semiconductors using non-covalent interactions may be used to engineer materials with interesting combinations mechanical and optoelectronic properties. To investigate the possibility of...

The cover picture shows a DNA recognition system that imitates the dimer formation of natural transcription factor pairs. Pyrrole-imidazole polyamides bind to programmable sequences and enable us target specific genomic regions. We have developed artificial factors by expanding function pyrrole-imidazole with other compounds (e.g., peptides epigenetic modulators), achieving gene regulation chem...

The combination of the Ugi four-component reaction (Ugi-4CR) with acyclic diene metathesis (ADMET) or thiol-ene polymerization led to the formation of poly-1-(alkylcarbamoyl) carboxamides, a new class of substituted polyamides with amide moieties in the polymer backbone, as well as its side chains. 10-Undecenoic acid, obtained by pyrolysis of ricinoleic acid, the main fatty acid of castor oil, ...

The positron annihilation technique using a slow positron beam can be used for the study of the vacancy profiles in typical reverse osmosis (RO) membranes. In this study, the vacancy profile in the polyamide membrane that exhibits a high permselectivity between ions and water was studied using the positron annihilation technique and molecular dynamics simulations. Orthopositronium (o-Ps) lifeti...
