Suppressing Oxygen Adsorption on Bulk Arsenic and 2D Arsenic Nanoflake Surfaces: The Role of Sb Doping.

The susceptibility of bulk and exfoliated nanolayered arsenic to oxidation has been a significant obstacle limiting their widespread application and safe disposal. Here we report a controllable antimony-doped (Sb-doped) method via chemical vapor transport (CVT) with SnI as a transport agent to prepare the bulk arsenic. After 96 h of exposure to air, the oxygen content on the surface of Sb-doped arsenic with SnI is 67% lower compared to the undoped arsenic with SnI, and 89% lower than the control group (undoped arsenic without SnI).

Integrating adsorption and in situ advanced oxidation for the treatment of organic wastewater by 3D carbon aerogel embedded with Fe-doped carbonitrides.

Wastewater containing organic pollutants with high toxicity and poor biodegradability poses a considerable threat to human health and the ecosystem. Although adsorption and advanced oxidation processes (AOPs) are currently the most widely used technologies for wastewater treatment, limitations of these two independent processes make the treatment effect unsatisfactory. Herein, a system of integrating adsorption and subsequent in situ AOPs is established by a 3D carbon aerogel embedded with Fe-doped carbonitrides (Fe-NC/CAG).

Enhancing the anti-oxidation stability of vapor-crystallized arsenic crystals via introducing iodine.

The oxidation of arsenic restricts its application in high-performance electronic devices and functional materials. Herein, a removable iodine-regulation method was proposed for the first time to enhance the anti-oxidation behavior of arsenic. In a gradient of 500-650 ℃, the introduction of 0.

Streptomyces geranii sp. nov., a novel endophytic actinobacterium isolated from root of Geranium carolinianum L.

A novel endophytic actinomycete, designated A301, was isolated from the root of Geranium carolinianum Linn collected from Mount Emei in China and characterized using a polyphasic approach. Growth occurred at 10-37 °C, pH 6-11 and in the presence of 0-5 % NaCl (w/v). Strain A301 contained ll-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan.
