A sensitive and selective extraction - spectrophotometric method for the determination of trace amounts of palladium is reported. The method is based on quantitative extraction of brownish tetrabutylammoium tetraiodopalladium (II) ion pair into a small valume of chloroform at pH 1.3-12.0, followed by spectrophotometric measurements. The Beer's law is obeyed over the range 0.02-1.09 <em...

27%-efficient perovskite/silicon tandem solar cells are achieved in n–i–p configuration by developing novel electron and hole selective contacts, which combine high broadband transparency with efficient charge extraction.

Olive pomace (OP) is the main by-product of olive oil industry produced in large quantities. Its valorization as a source phenolic bioactive compounds paramount for sustainable growth related industries. This work proposes an intensified process to maximize recovery dry extracts using hydroalcoholic mixtures. Supercritical carbon dioxide defatting pre-treatment was performed. Following this, pr...
