Automatic source detection in astronomical images
The use of automatic algorithms to detect astronomical sources (stars, galaxies, gas, dust or cosmic rays) becomes of great importance because of the increasing amount of astronomical images and the inefficiency and ...
Development of highly structured non-heme iron catalysts for selective C-H group oxidations
Catalytic oxidation reactions of hydrocarbons that occur in the active site of metalloenzymes exhibit high efficiency and exquisite regio- and stereoselectivity under mild experimental conditions. We describe the efficient ...
Disseny i síntesi de lipopèptids cíclics i de pèptids conjugats derivats de BPC194 amb activitat antimicrobiana
Les malalties causades per bacteris i fongs són responsables d’importants pèrdues econòmiques en cultius. Es considera que els pèptids antimicrobians, naturals i sintètics, són uns bons candidats per a ser utilitzats com ...
