Flexible use of commercial rhenium disulfide for various theranostic applications.

Rhenium disulfide (ReS) with distinct physicochemical properties has shown promising potential in disease theranostics, such as drug delivery, computed tomography (CT), radiotherapy, and photothermal therapy (PTT). However, the synthesis and post-modification of ReS agents for different application scenarios are time- and energy-consuming, which seriously hinders the clinical translation of ReS. Herein, we proposed three facile excipient strategies for different theranostic applications of ReS just through the flexible use of commercial ReS powder.

Portable electrochemical carbon cloth analysis device for differential pulse anodic stripping voltammetry determination of Pb.

A novel electrochemical carbon cloth (CC) analysis device (eCAD) is proposed for the determination of Pb in environmental water samples, which was assembled using a single-step functional CC as both the sensing and the substrate material. The modified CC was characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, Raman spectra, and electrochemical impedance spectroscopy. The increase in electrochemical activity is due to the increased defective extent and excellent electrochemical activity of CC.

Detection of water-molecular-motion configuration in patients with lupus nephritis: a primary study using diffusion-weighted imaging.

Background: Lupus nephritis (LN) is one of most common types of secondary glomerulonephritis, which is characterized by longitudinal pathological changes.

There are few reported measurements of water diffusion in patients with LN, and the nature of water diffusion across the entire depth of the renal parenchyma remains largely unknown.

Adsorption behaviour and mechanism of the PFOS substitute OBS (sodium -perfluorous nonenoxybenzene sulfonate) on activated carbon.
