Abstract The remediation of viscous oil spills and organic contaminants in harsh environments requires sorbents that possess not only adsorption capability but also exceptional thermal and chemical stability. Herein, we report the facile synthesis of a novel class of fluorinated copolyimine xerogels (XG-CoPI) following the solvent exchange method via the polycondensation of terephthalaldehyde (PA), 4,4′-oxydianiline (ODA),...

Abstract In this paper, we study the structure of locally generalized radical subgroups of the general skew linear group GLn(D) of degree n ≥ 1 over a division ring D. Among results, we show that if G is a locally generalized radical almost subnormal subgroup of GLn(D), then G is central provided D is not a locally finite field in case n...
