Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere
Advanced Engineering Materials, EarlyView.A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Admixture history of the South African "Coloured" populations
, 2019 Admixed people formed from colonial era migrations are a major feature of present-day diversity. In Southern Africa, establishment of the Dutch Cape Colony instigated the so-called "Coloured" communities, associated, essentialistically, with 'mixed descent'. This multi-way admixture involved diverse regional groups producing a fascinating genetic story.

Estimation of genetic admixture proportions via haplotypes
Computational and Structural Biotechnology JournalEstimation of ancestral admixture is essential for creating personal genealogies, studying human history, and conducting genome-wide association studies (GWAS). The following three primary methods exist for estimating admixture coefficients.
