This work report, for the first time, the co-doping of mesoporous TiO2 with Cd2+ and La3+ cations for improved performance of dye-sensitized solar cells (DSSCs). Cd2+ ions modify the TiO2 lattice interstitially and lower the band gap enabling better electr ...
CeO2-based nanomaterials and their rich redox chemistry provide a possible route to pollutant abatement in various heterogeneous processes, and are in particular used as sorbents for flue gases and as oxygen promoters in three-way catalytic converters. The ...
We present an implicit solvation approach where the interface-between the quantum-mechanical solute and the surrounding environment is, described by a fully continuous permittivity built up with atomic-centered "soft" spheres. This approach combines many o ...
We report a light, flexible, and low-power poly(ionic liquid)/alumina composite CO2 sensor. We monitor the direct-current resistance changes as a function of CO2 concentration and relative humidity and demonstrate fast and reversible sensing kinetics. More ...
Ruthenium complexes of the type [RuCl(eta(6)-arene)-(NN)]X (X = BF4 or BPh4) featuring an eta(6)-arene ligand modified with an imidazolium ring and incorporating the bis(azo) chelating (NN) ligands 2-hydroxyphenylbis(3,5-dimethylpyrazol-1-yl) methane or 2- ...
Measuring the concentration of different compounds in aquatic ecosystem and understanding their impact on the environment are some of the main objectives in the environmental monitoring field. Trace metals, nutrients, volatile organic compounds (VOCs), bio ...
Hybrid magnetic nanoparticles based on poly(methylmethacrylate) (PMMA) and super-paramagnetic iron oxide nanopaticles (SPIONs) with selective surface modification has been developed for heavy metal removal by applying external magnetic fields. The nanopart ...
High-resolution powder x-ray diffraction and single-crystal neutron diffraction were used to investigate the crystal structure and magnetic ordering of the compound Pr1-xCax VO3 (0
During the past few years, organic lead halogen perovskites have emerged as a class of highly promising solar cell materials, with certified solar cell efficiencies now surpassing 20%. Concerns have, however, been raised about the possible environmental an ...
