Two-dimensional (2D) black arsenic phosphorus (b-AsP) material has been attracting considerable attention for its extraordinary properties. However, its application in large-scale device fabrication remains challenging due to the limited scale and irregular shape. Here, we found the special effect of Te upon growth of b-AsP and developed a novel Te-regulated steady growth (Te-SG) strategy to obtain high-quality b-AsP single crystal.

Background: Currently, there remains a high percentage of complications after lumbar discectomy, while there is no uniform tactic to prevent their development. Purpose of the study was to compare the clinical efficacy and return to work rate (RWR) after total disk replacement (TDR) and microsurgical lumbar discectomy (MLD) in railway workers with lumbar disk herniation (LDH).
Methods: We randomly assigned 75 patients out of a total of 81 patients, between 25 and 35 years of age who had one level LDH to undergo single-level TDR surgery (group I, n=37) or MLD surgery (group II, n=38) in the L4-L5 or L5-S1 segments.
Light-driven in-situ synthesis of nano-sulfur and graphene oxide composites for efficient removal of heavy metal ions.

Sulfur nanoparticles (SNPs) and their composites are promising for heavy metal adsorption, yet current SNPs often lack surface S, leading to low affinity toward heavy metal and ease of aggregation. Here, we report a simple light-driven method for facile prepare SNPs with surfaces enriched with S and in-situ load them onto graphene oxide (GO) to fabricate GO-S composites. Under illumination, the O generated by photosensitizer phloxine B was able to oxidize S into elemental SNPs.

Background And Purpose: To present the clinical outcomes of two series of patients treated with carbon-ion radiotherapy (CIRT) and definitive photon radiotherapy (RT) for adenoid cystic carcinoma of the head and neck (HN-ACC).
Material And Methods: The first cohort of six patients was referred from Oslo University Hospital (OUS) to Centro Nazionale di Adroterapia Oncologica (CNAO, Pavia, Italy) for CIRT in 2014-2017. The second cohort included 18 patients treated with definitive photon RT at OUS in 2005-2017.
