Using ab initio calculations, we study the magnetic features of the FemCon, m+n 6 clusters and investigate the role of Co in enhancing the magnetism of the Fe grains. Our results show that the role of Co appears to be that of inducing structural changes in the grain which may lead to enhanced magnetic moments for the Co-Fe clusters as a result of the rehybridization process and the following re...

Introduction: Impacts on lunar soils produce melt and vapor in an approximate proportion of 7:1 [1]. The melt scavenges soil grains of diverse size, quenches and forms agglutinates, thereby converting surface correlated components of soil grains as volume correlated components; simultaneously, parts of the vapor may condense or escape. Cumulative small impacts increase the maturity of the soils...

The effect of Ni impurity on the self-diffusivity of bSn in the (1 0 1) symmetric tilt grain boundary is investigated. Using molecular dynamics simulations over a temperature range of 300–450 K. It is shown that Ni solute decreases the grain boundary self-diffusivity of bSn as the amount of solute in grain boundary increases. We also study the solute effect on the diffusive width of grain bound...

Rapid development of automotive industry brings also increased requirements for sheets properties, involving relatively high strength and good formability together with excellent corrosion resistance. Increasing requests for corrosion resistance lead to the production of coated car parts, protected mainly by zinc coatings. Whereas, majority of European producers of passenger cars use preferenti...

We investigate the impact of dust-induced gas fragmentation on the formation of the first low-mass, metal-poor stars (<1M ) in the early universe. Previous work has shown the existence of a critical dust-to-gas ratio, below which dust thermal cooling cannot cause gas fragmentation. Assuming that the first dust is silicon-based, we compute critical dust-to-gas ratios and associated critical sili...

OBJECTIVE To develop meal plans using grain-based foods demonstrating how to incorporate wholegrain foods into a balanced diet for weight maintenance for different cuisines. The present study examines the ability of meal plans with ≥4 grain-based servings daily to meet nutrient recommendations using lacto-ovo vegetarian and rice-based cuisines. DESIGN Eighteen plans from each cuisine for thre...

Annealing of amorphous precursor alloys, with compositions (Fe,Co!88M7B4Cu1 ~M5Zr, Nb, Hf!, above their primary crystallization temperature results in the nanocrystallization of the ferromagnetic a8-FeCo phase. This work describes results of the characterization of these alloys, including morphological and chemical stability of the a8-FeCo phase, examination of alloy compositions, and developme...

Introduction: We have used a variety of techniques – TEM, synchrotron – as part of the UK Stardust consortium in order to identify and constrain the origin of oxides and thus demonstrate some affinities between Wild 2 and other planetary materials such as chondrite groups or IDPs. We are finding that oxidised phases in Wild 2 have a variety of origins. Studying Fe-bearing oxide phases in the St...
