Unique S-scheme structures in electrostatic self-assembled ReS-TiO for high-efficiency perfluorooctanoic acid removal.

Perfluorinated compounds (PFCs), recognized as persistent organic pollutants, resist degradation in the environment due to the high bond energy of the C-F. Increasing carrier density via adopting electrostatic self-assembly strategy has been shown to effectively cleave C-F bonds. In this work, a unique S-scheme structure was fabricated by combining oppositely charged semiconductors, TiO and ReS, through electrostatic self-assembly.

Effects of azo dye on simultaneous biological removal of azo dye and nutrients in wastewater.

The potential disrupting effects of Azo dye on wastewater nutrients removal deserved more analysis. In this study, 15 days exposure experiments were conducted with alizarin yellow R (AYR) as a model dye to determine whether the dye caused adverse effects on biological removal of both the dye and nutrients in acclimated anaerobic-aerobic-anoxic sequencing batch reactors. The results showed that the AYR removal efficiency was, respectively, 85.

Enhanced bio-hydrogen production from protein wastewater by altering protein structure and amino acids acidification type.

Enhanced bio-hydrogen production from protein wastewater by altering protein structure and amino acids acidification type via pH control was investigated. The hydrogen production reached 205.2 mL/g-protein when protein wastewater was pretreated at pH 12 and then fermented at pH 10.

Complete mitochondrial genome of the double-striped cockroach Blattella bisignata (Insecta: Blattaria: Blaberoidea).

In this work, we sequenced the complete mitochondrial genome of Blaberoidea species, Blattella bisignata. The circle genome (16,470 bp) consists of 13 protein-coding, 22 tRNA, and 2 rRNA genes, and an A+T-rich region. The A+T-rich region, which contains five long repeat sequences, is located between the small rRNA and tRNA(Ile) and is 1705 bp in length.

Complete mitochondrial genomes of two cockroaches, Blattella germanica and Periplaneta americana, and the phylogenetic position of termites.

The mitochondrial genomes are one of the most information-rich markers in phylogenetics. The relationships within superorder Dictyoptera have been debated in the literature. However, the closely related termites (Isoptera) are retained as unranked taxon within the order Blattaria (cockroaches).

Bis(1,3-diethyl-benzimidazolium) tetra-bromidomercurate(II).

In the title compound, (C(11)H(15)N(2))(2)[HgBr(4)], the tetra-coordinated Hg(II) center of the complex anion adopts a distorted tetra-hedral geometry [Hg-Br = 2.5755 (8)-2.623 (11) Å and Br-Hg-Br = 103.
