Aberrometry: basic science and clinical applications [PDF]
, 2012 This paper addresses the concept, measurement and applications of wave aberrations. The ocular optics is not perfect. Apart from conventional low order aberrations (such as defocus and astigmatism) retinal images are degraded by other high order ...

ShockABSTRACT Potential radiation exposure is a general concern, but there still lacks radioprotective countermeasures. Here, we found a small molecular near-infrared dye IR-780, which promoted hematopoietic stem cells (HSCs) into quiescence to resist stress.

In Situ Lipoprotein‐seeking Dye for in Vivo Real‐Time Imaging of Lipid Dysregulation Diseases
Advanced Science, EarlyView.This study develops lipoprotein‐seeking NIR‐II dyes that specifically bind circulating lipoproteins. These dyes form ultra‐stable complexes with endogenous lipoprotein, enabling real‐time, high‐contrast imaging of fatty liver and atherosclerotic plaques. Tunable binding kinetics allow customized imaging windows.

Advanced Science, EarlyView.This study investigates how endothelial monolayers balance cohesion and plasticity during mechanical stimulation. In HUVECs, shear stress induces a tension‐sensitive intermediate state in which junctional VE‐cadherin and actomyosin relaxation levels coordinate actin/integrin remodeling. This rapid, reversible state strengthens cell junctions, preserves

Sustainable KCl‐Assisted PbI2 Recycling for High‐Performance Quantum Dot Solar Cells
Advanced Science, EarlyView.An additive‐assisted lead recycling strategy is developed by introducing trace KCl during PbI2 recrystallization from spent lead‐acid batteries. KCl regulates crystallization and impurity removal, yielding high‐purity PbI2 and enabling the formation of colloidally stable PbS and CsPbI3 quantum dots.

Advanced Science, EarlyView.A polymer‐intercalated modulation assembly strategy was proposed to synthesize mesoporous single‐crystalline BiVO4 with tunable pore structure by co‐assembly of inorganic–organic composite through coordination bonds and hydrogen bonds. Thanks to single‐crystalline properties and mesoporous structure with vanadium vacancy microenvironment, the prepared ...
