Metal particle shape: A practical perspective
Metal Powder Report, 2018The choice of appropriate processing conditions in powder metallurgy and the achievement of the required properties for the final metal components greatly depend on the shape of the solid phase.

Morphology-dependent nanocatalysis: metal particles
Dalton Transactions, 2011The rapid development of materials science now enables tailoring of metal and metal oxide particles with tunable size and shape at the nanometre level. As a result, nanocatalysis is undergoing an explosive growth, and it has been seen that the size and shape of a catalyst particle tremendously affects the reaction performance.

Sabatier principle of metal-support interaction for design of ultrastable metal nanocatalysts
Science, 2021Description Rational design of stable nanocatalysts Sintering of nanoparticles is one of the main causes of their catalytic deactivation. Rational design of nanocatalysts that are stable against sintering is a grand challenge in heterogenous catalysis ...

Bulletin of the Lebedev Physics Institute, 2009
The effect of electron collisions with lattice atoms in metals on metal particle polarization in an ac electric field was analyzed. It was shown that, in contrast to collisionless (free) electron gas, an increase in the negative electronic permittivity with decreasing electric field frequency in relaxation metal particles is limited by the conductivity

Heavy metal particle characterisation
Nature, 1974THE aerial fallout of heavy metals downwind of the Avonmouth industrial complex has been well documented. Analyses of vegetation1 and moss bags2 show decreasing levels of lead, cadmium and zinc with increasing distance from the complex. The precise nature of the heavy metal fallout, however, has been neglected although the chemical and physical state ...

Superconductivity of small metallic particles
Surface Science Letters, 1980Abstract BCS theory improved with respect to electron number conservation developed by Iwamoto and Ōnishi, is applied to the calculation of the ground state energy of small metallic superconductors. The excitation energy is also discussed with the use of the above method and the perturbation method, and the size effect on the spin magnetism is ...
