Expert Reviews

Lanthanum Oxide Nanoparticles: Metal oxides play a very important role in many areas of chemistry, physics and materials science.  The metal elements are able to form a large diversity of oxide compounds. These can adopt a vast number of structural geometries with an electronic structure that can exhibit metallic, semiconductor or insulator character. In technological applications, oxides are used in the fabrication of microelectronic circuits, sensors, piezoelectric devices, fuel cells, coatings for the passivation of surfaces against corrosion, and as catalysts.

Dr. Mark Brown , (Georgia Institute of Technology in Atlanta,USA)

Lanthanum Oxide Nanoparticles: Oxide nanoparticles can exhibit unique physical and chemical properties due to their limited size and a high density of corner or edge surface sites. Particle size is expected to influence three important groups of basic properties in any material. The first one comprises the structural characteristics, namely the lattice symmetry and cell parameters.

Dr. Ms. Cristiana Barzetti , (University of Cagliari-Department of Chemical Engineering and Material Science, Italy)

Lanthanum Oxide Nanoparticles: Bulk oxides are usually robust and stable systems with well-defined crystallographic structures. However, the growing importance of surface free energy and stress with decreasing particle size must be considered: changes in thermodynamic stability associate with size can induce modification of cell parameters and/or structural transformations and in extreme cases the nanoparticle can disappear due to interactions with its surrounding environment and a high surface free energy.  In order to display mechanical or structural stability, a nanoparticle must have a low surface free energy.

Dr. Jang Huang, Ph.D , (Shandong Science and Technology University, China)

Lanthanum Oxide Nanoparticles: The effect of size is also related to the electronic properties of the oxide. In any material, the nanostruture produces the quantum size or confinement effects which essentially arise from the presence of discrete, atom-like electronic states. From a solid-state point of view, these states can be considered as being a superposition of bulk-like states with a concomitant increase in oscillator strength.  Additional general electronic effects of quantum confinement experimentally probed on oxides are related to the energy shift of exciton levels and optical bandgap.

Dr. Darren Chandler, Ph.D, (Manchester Metropolitan University, U.K)

Lanthanum Oxide Nanoparticles: Structural and electronic properties drive the physical and chemical properties of the solid, the third group of properties influenced by size in a simple classification. In their bulk state, many oxides have wide band gaps and a low reactivityA decrease in the average size of an oxide particle do in fact change the magnitude of the band gap, with strong influence in the conductivity and chemical reactivity.
