Modulating the properties of g-C3N4 through two-step annealing and ionic-liquid gating.

We reported a novel strategy by the combination of two-step annealing treatment and ionic-liquid gating technology for effectively regulating the properties of g-C3N4, especially largely reducing the recombination rate of the electron-hole pairs, with evidenced by the remarkable reduction of photoluminescence (PL) intensity. Firstly, graphitic carbon nitrides with typical layered structure were obtained by annealing melamine with temperature above 500°C. Further annealing at 600°C with much longer time (from 2 hours to 12 hours) were found to effectively reduce the imperfections or defects, and thus the PL intensity (49% reduction).

Natural selection shapes codon usage and host adaptation of NS1 in mosquito-borne pathogenic flaviviruses.

The NS1 protein of nine mosquito-borne flaviviruses, including Dengue virus 1-4, Japanese encephalitis virus, West Nile virus, Yellow fever virus, Tembusu virus, and Zika virus, shows distinct codon usage and evolutionary traits. Codon usage analysis shows notable base composition bias and non-conservatism in NS1, with distinct evolutionary traits from its ORF. Analysis of relative synonymous codon usage (RSCU) indicates that the NS1 genes exhibit non-conservative RSCU patterns within different mosquito-borne pathogenic flaviviruses.

Molecular phenotypes of critical illness confer prognostic and biological enrichment in sub-Saharan Africa: a prospective cohort study from Uganda.

The generalisability of critical illness molecular phenotypes to low- and middle-income countries (LMICs) is unknown.
