A comprehensive investigation of four polydiketopyrrolopyrroles (PDPPs) with increasing ethylene glycol (EG) content and varying nature comonomer is presented, guidelines for the design efficient mixed ion-electron conductors (MIECs) are deduced. The studies in NaCl electrolyte-gated organic electrochemical transistors (OECTs) reveal that a high amount EG on DPP moiety essential MIEC. PDPP cont...

There is growing interest in the recovery of pure palladium (Pd) compound from cemented Pd spent electroplating solutions due to increasing demand for Pd, and there considerable motivation develop an efficient process. In conventional methods leaching metal, HCl containing oxidizing agents are employed. this work, ethylene glycol (EG) replaced water as a diluent solution such H2O2, NaClO NaClO3...

The electronic structure of NiO nanometric planar islands on highly oriented pyrolitic graphite has been studied by means of the Ni 2p and O 1s x-ray absorption spectra. The O 1s spectrum of the early stages of growth shows a double peak at threshold which is attributed to a splitting of the unoccupied Ni eg states. This spectrum is compared to previous results for 3 nm NiO nanoparticles which ...

The metal-insulator transition is mixed-valence manganites of the ~La0.7Ca0.3!MnO3 type is ascribed to a modification of the spin-dependent potential JHs–S associated with the onset of magnetic order at TC . Here JH is the on-site Hund’s-rule exchange coupling of an eg electron with s51/2 to the t2g ion core with S 53/2. Above TC, the eg electrons are localized by the random spin-dependent pote...

The optical bandgap (Eg) of transition metal nitroprussides remains practically undocumented, probably because these materials are usually considered wide solids, characterized by a strong metal-ligand charge-transfer band below 500 nm. In this contribution, we reporting experimental and DFT computed data for both, 3D 2D phases Zn Cd to get physical insight into the structure effect on material...
