We demonstrate the broad distribution of particulate thiols in the western North Pacific and show that their main source is marine phytoplankton. Our analysis indicates that differences in thiol concentrations between ocean areas are significantly influenced by water mass properties, phytoplankton composition, and environmental stress. In the oligotrophic, highly transparent subtropical North Pacific Central Water, we find indications that "preformed" glutathione, retained in particulates derived from dead phytoplankton, makes a significant contribution.

Researchers used electroluminescence-detected magnetic resonance to directly observe electron-hole pairs in operating light-emitting electrochemical cells. They found that ion-driven changes in the internal electric field strongly affect recombination efficiency. Lower-voltage, more stable electric fields promote light emission, a discovery that identifies electric field management as a key factor in improving organic optoelectronic devices.

A research team from China University of Mining and Technology has designed a groundbreaking folding magnetic soft sheet robot powered by magnetorheological fluids, featuring real-time reconfigurable magnetization, reversible multi-angle folding, and high-precision targeted drug delivery capabilities. The robot can reduce its surface area to one-third of the original via magnetic control, adapt to the complex and narrow cavities of the gastrointestinal tract, and achieve stable movement on various surfaces as well as in liquid environments. Validated through ex vivo porcine stomach experiments and ultrasonic detection, this robot realizes accurate drug delivery to lesion sites within an average of 5 minutes, presenting a promising noninvasive medical device for gastrointestinal tract operations.A research team from China University of Mining and Technology has designed a groundbreaking folding magnetic soft sheet robot powered by magnetorheological fluids, featuring real-time reconfigurable magnetization, reversible multi-angle folding, and high-precision targeted drug delivery capabilities.
