The role of Cerium, Europium and Erbium doped TiO2 photocatalysts in water treatment: A mini-review

open access: yesChemical Engineering Journal Advances, 2022
Heterogeneous photocatalysis is a promising environmentally friendly strategy for removing contaminants of emerging concern from water, with titanium dioxide being the most studied and exploited photocatalyst, thanks to its good optical and electrical ...

Comparative Study of f-Element Electronic Structure across a Series of Multimetallic Actinide and Lanthanoid-Actinide Complexes Possessing Redox-Active Bridging Ligands [PDF]

open access: yesInorganic Chemistry, 2010
A comparative examination of the electronic interactions across a series of trimetallic actinide and mixed lanthanide-actinide and lanthanum-actinide complexes is presented. Using reduced, radical terpyridyl ligands as conduits in a bridging framework to promote intramolecular metal-metal communication, studies containing structural, electrochemical ...

Valencies of the lanthanides [PDF]

open access: yes, 2017
The valencies of the lanthanides vary more than was once thought. In addition to valencies associated with a half-full shell, there are valencies associated with a quarter- and three-quarter-full shell.

Complex Structures of Intermetallic Compounds Interpreted as Intergrowth of Segments of Simple Structures

open access: yesCHIMIA, 1985
By the end of 1982 more than 2000 structure types were known for intermetallic compounds (elements, binary and multicomponent alloys) according to «Pearson’s Handbook of Crystallographic Data for Intermetallic Phases».

Photochemical upconversion present status and prospects for its application to solar energy conversion [PDF]

open access: yes, 2015
All photovoltaic solar cells transmit photons with energies below the absorption threshold bandgap of the absorber material, which are therefore usually lost for the purpose of solar energy conversion.

Current rectification in a single molecule diode: the role of electrode coupling [PDF]

open access: yes, 2015
We demonstrate large rectification ratios (> 100) in single-molecule junctions based on a metal-oxide cluster (polyoxometalate), using a scanning tunneling microscope (STM) both at ambient conditions and at low temperature. These rectification ratios are

Use of rare earth oxides as tracers to identify sediment source areas for agricultural hillslopes [PDF]

open access: yes, 2010
Understanding sediment sources is essential to enable more effective targeting of in-field mitigation approaches to reduce diffuse pollution from agricultural land.

Proximity to Fermi-surface topological change in superconducting LaO0.54F0.46BiS2 [PDF]

open access: yes, 2014
The electronic structure of nearly optimally-doped novel superconductor LaO$_{1-x}$F$_x$BiS$_2$ (${\it x}$ = 0.46) was investigated using angle-resolved photoemission spectroscopy (ARPES).

Crystal field analysis of Dy and Tm implanted silicon for photonic and quantum technologies [PDF]

open access: yes, 2014
We report the lattice site and symmetry of optically active Dy3+ and Tm3+ implanted Si. Local symmetry was determined by fitting crystal field parameters (CFPs), corresponding to various common symmetries, to the ground state splitting determined by ...
