DOI: 10.1016/j.cclet.2020.04.048
Abstract: Abstract The removal of ciprofloxacin (CIP) in sulfur-mediated bioprocesses, e.g., sulfate-reducing bacteria (SRB)-mediated process and sulfur-oxidizing bacteria (SOB)-mediated process, was examined for the first time. The results showed that the SRB-mediated process had more efficient… read more here.

DOI: 10.1016/j.chempr.2019.10.021
Abstract: Summary Evaporation-condensation of red phosphorous to prepare phosphorous-based anodes inevitably generates white P residual, severely limiting its practical application due to the serious safety concern. Rather than removing the white P residual by complicated post-treatments,… read more here.

DOI: 10.1039/c8qo00410b
Abstract: A transition-metal-free, sulfur mediated propargylic C–H alkylation reaction was realized through a one-pot procedure. The reaction design involves an initial addition between alkynes and triflic anhydride activated sulfoxides, and a subsequent [2,3]-sigmatropic rearrangement of the… read more here.

DOI: 10.1055/a-1534-0466
Abstract: Methods to afford pyrrolo[1,2-a]quinoxalines often require the use of prefunctionalized aniline precursors, transition metals, and/or harsh conditions. Herein we describe a simple coupling of 1-(2-nitroaryl)pyrroles and arylacetic acids, in the presence of elemental sulfur, to… read more here.
