Meteorological drivers of interannual variation in transparency of mountain lakes

open access: yesArctic, Antarctic, and Alpine Research, 2020
In mountain lakes, water transparency is regulated primarily by materials loaded from the surrounding catchment. Consequently, transparency within a lake can vary over time due to meteorological conditions that affect hydrologic inputs. Furthermore, lake

Biomineralization‐Inspired Membranization Toward Structural Enhancement of Coacervate Community

open access: yesAdvanced Science, EarlyView.
The spontaneous formation of a mineralized membrane on the surface of coacervate droplets is facilitated by Fe3+ ions and redox reaction, accompanied by the aggregation of the coacervate droplets. These membranized coacervate assemblages not only retain the capacity for biomolecule sequestration and enzyme catalysis but also exhibit enhanced structural

Colloidal Synthesis of Sub‐1‐nm PbSe Nanowires via Cation Exchange for High‐Performance Near‐Infrared Self‐Powered Photoelectrochemical‐Type Photodetectors

open access: yesAdvanced Science, EarlyView.
This study presents a noval cation‐exchange approach in N, N‐dimethylformamide solvent to synthesize sub‐1‐nm PbSe nanowires, with sub‐1‐nm ZnSe nanowires as the starting material. By capitalizing on the unique near‐infrared absorption characteristics and superior carrier transport properties of these nanowires, this is successfully developed high ...

Stochastic View of Photon Migration in Turbid Media [PDF]

open access: yesarXiv, 2004
Light propagation in an infinite uniform turbid medium is treated as a Markov stochastic process of photons to provide an intuitive framework for photon migration. The macroscopic physical quantities of photon migration are shown to be completely determined by the microscopic statistics of the photon propagation direction in direction space and a ...

A Universal and Versatile Zwitterionic Coating for Blood‐Contacting Catheters with Long Lengths and Complex Geometries

open access: yesAdvanced Science, EarlyView.
A universal and versatile zwitterion coating strategy is developed for blood‐contacting catheters with long lengths and complex geometries. The coating exhibits near‐zero fouling, superior anticoagulation, and selective biocapturing properties while maintaining excellent stability under dynamic blood flow.
