Copper-based sulfides are attractive candidates for NIR I and II responsive photothermal therapy but often suffer from high hydrophobicity, suboptimal photothermal conversion, and poor biostability and biocompatibility. In the present work, a rapid, one-pot synthesis method was developed to obtain Au-doped CuS (ACSH NDs) dual plasmonic nanodots. ACSH NDs exhibit excellent peroxidase-like catalytic activity for pH-responsive OH radical generation along with efficient glutathione depletion under tumor microenvironment mimicking conditions.

The purpose of the present study was to understand how executives responsible for Diversity and Inclusion construct their identities while occupying positions of "Marginal Leadership," and how they deal with threats to such identities. We conducted qualitative and inductive research with Brazilian executives in 66 organizations, focusing on their experiences as leaders. In our resulting model, we theorized that leaders in positions of Marginal Leadership demonstrate little role clarity, resources, and confidence for the exercise of their activities, suffering threats to their identities, which are not observed in executives occupying positions in more traditional functions such as Finance, Production, and Marketing.

A pilot project was undertaken to engage farmers, confirm cases with diagnostic methods and identify specific barriers to control, with the aim of informing future control programmes.
Methods: Through farmers self-reporting suspected outbreaks, on-farm risk assessments and clinical investigations were carried out by the farm's veterinary surgeon, who utilised light microscopy and serological testing to diagnose scab.
Insight into the microbial diversity and community in the sacrificial pits of Sanxingdui site (Sichuan, China).

School of Cultural Heritage, Northwest University, Xi'an, China.
Introduction: The Sanxingdui site (Sichuan, China) is the typical representative of the ancient Shu culture, which lasts from the late Neolithic to early Western Zhou. The sacrificial pits are located in the core region of Sanxingdui site, and numerous artifacts are unearthed including ivory, seashells, bronzes, pottery, jade, stone, gold, bone, and horn products. The function of the pits and buried artifacts has always been the focus, but the microbiome around artifacts attracts less attention.

Iodine in the atmosphere destroys ozone and can nucleate particles by formation of iodic acid, HIO. Recent field observations suggest iodate recycles from particles sustaining significant gas-phase IO radical concentrations (0.06 pptv) in aged stratospheric air, and in elevated dust plumes.
