Central Asia, Euro-centrism and Colonialism by N. T. Nurulla-Khodzhaeva

“…In the process of such explication, the most important role is allocated to the modern culture, which encouraged the formation of the paradox, represented to us via the paraphrased Soviet aphorism: modernity and coloniality are twin brothers. The initiation of the process of decolonizing the mind within the five republics of the region is possible. …”

Atomistic behavior of Cu–Cu solid-state bonding in polycrystalline Cu with high-density boundaries by Hiroaki Tatsumi, C.R. Kao, Hiroshi Nishikawa

“…We modeled two polycrystalline Cu structures with high-density boundaries—a randomly oriented nanocrystalline (NC) structure with high-density grain boundaries (GBs) and a unidirectional [111]-oriented columnar nanotwinned (NT) structure with high-density twin boundaries (TBs). Thermocompression bonding was simulated for both structures, with the bonding surfaces designed to replicate surface roughness. …”
