The electrochemical nitrate reduction reaction (NO3RR) has the potential for distributed water treatment and renewable chemical synthesis. Cu is an active monometallic electrocatalyst NO3RR in acidic alkaline electrolytes, where activity limited by of adsorbed to nitrite. Oxygen-vacancy forming metal-oxide supports provide sites N-O bond activation thermal reduction, impacting product distribut...

Correction for 'Single-molecule magnet behaviour in polynuclear assembly of trivalent cerium ions with polyoxomolybdates' by A. Ben Khélifa, et al., Dalton Trans., 2015, 44, 16458-16464.

An isopolyoxomolybdate-based POM is coordinated to trivalent cerium ions to afford a hybrid complex namely, [Ce(dmso)8][Ce(η2-NO3)2(dmso)4(α-Mo8O26)0.5][Mo6O19]. The original electrostatic environment created around the Ce(III) by its coordination to the isopolyoxomolybdate core induces complex single-molecule magnet behavior.

Ultraviolet (UV) miniature cerium fluoride lasers have been demonstrated using a low cost, frequency-quadrupled microchip Nd:YAG pump laser. The use of miniature laser cavities was shown to significantly improve the laser performance in the low pump power region. We have achieved slope efficiencies up to 70% and pump thresholds as low as 100 nJ. Continuous tuning from 306 nm to 338 nm was achie...

a pvc-based membrane containing cerium phosphate was developed. unlike the cerium phosphate itself that acts as a cation exchanger, the membrane exhibited anion-exchange properties. therefore, the utility of this compound as a sensory element for detection of molybdate ions was pursued. the response of molybdate selective electrode based on this membrane was perfectly linear in the concentratio...

In this paper we evaluate the performance of density functional theory with the B3LYP functional for calculations on ceria (CeO(2)) and cerium sesquioxide (Ce(2)O(3)). We demonstrate that B3LYP is able to describe CeO(2) and Ce(2)O(3) reasonably well. When compared to other functionals, B3LYP performs slightly better than the hybrid functional PBE0 for the electronic properties but slightly wor...

The plasma potential, V(p), is a key quantity in experimental plasma physics. Its spatial gradients directly yield the electrostatic field present. Emissive probes operating under space-charge limited emission conditions float close to V(p) even under time-varying conditions. Throughout their long history in plasma physics, they have mostly been constructed with resistively heated tungsten wire...

Understanding and manipulating micelle morphology are key to exploiting surfactants in various applications. Recent studies have shown surfactant self-assembly a variety of Deep Eutectic Solvents (DESs) where both the nature interaction molecule with solvent components influence size, shape, micelles formed. So far, formation has only been reported type III DESs, consisting solely organic speci...

We report X-Ray Absorption and X-Ray Photoemission measurements on crystal l ine and amorphous Pdl-xCex alloys. I n this system, cerium presents a concentration-induced valence change. A correlat ion between cerium electronic configuration and density of occupied states have been shown.Valence anomalies appear to be due t o the high palladium 4d density of states near the Ferrni level. The effe...
