The stability of palladium supported on ceria (Pd/CeO2) was studied during liquid flow transfer hydrogenation using primary and secondary alcohols as hydrogen donors. For primary alcohols, the ceria support was reduced to cerium hydroxy carbonate within 14 h and was a contributing factor toward catalyst deactivation. For secondary alcohols, cerium hydroxy carbonate was not observed during the s...

The germanide Ce2Rh3Ge5 was synthesized from the elements in a bismuth flux, and the structure was refined from single-crystal X-ray diffractometer data: U2Co3Si5 type, Ibam, a = 1010.1(2), b = 1210.4(2), c = 599.1(1) pm, wR = 0.0596, 760 structure factors, 31 variables. The rhodium and germanium atoms build up a three-dimensional [Rh3Ge5] network (242 – 269 pm Rh–Ge; 300 pm Rh–Rh; 266 pm Ge–Ge...

The effects of cerium and lanthanum on the vegetative and reproductive growth of Arabidopsis thaliana were investigated. Addition of cerium (III) nitrate (0.5-50μM) and/or lanthanum nitrate (0.5-50μM) to the culture medium and the potting mix showed varied results. Pot trials were done with uniform conditions for light, water and temperature. Factors examined include root length, height, number...

Interactions of nanoparticles with biological matter-both somatically and in nature-draw scientists' attention. Nanoparticulate systems are believed to be our saviors, acting as versatile drug delivery vehicles. However, they can also cause life-threatening bodily damage. One of the most important properties of nanocrystalline cerium dioxide is its antioxidant activity, which decreases the abun...

The Meccano of heavy fermion systems is shown on different cases going from anomalous monochalcogenides to cerium intermetallic compounds with special focus on the ideal case of the CeRu2Si2 series. Discussion is made in the frame of the interplay between valence, electronic structure (Fermi surface), and magnetism. The nice tools given by the temperature, the pressure, and the magnetic field a...

We present a new family of metal based ionic liquids (MetILs) for use in flow battery applications. These materials are synthesized in a single step by simply heating a metal salt in the presence of a ligand containing multiple polarizable functional groups. The utility of this reaction has allowed a wide range of metal cation, anion and ligand combinations to be prepared and electrochemically ...

Over the last decade, engineered nanomaterials (NMs) brought a revolutionary development in many sectors of human life including electronics, paints, textiles, food, agriculture, and health care. However, the exponential growth in the number of NMs applications resulted in uncertainties regarding their environmental impacts. Currently, the common approach for assessing the toxicity of NMs such ...
