Inhomogeneous Mode-Coupling Theory and Growing Dynamic Length in Supercooled Liquids
, 2006 We extend Mode-Coupling Theory (MCT) to inhomogeneous situations, relevant for supercooled liquid in pores, close to a surface, or in an external field.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

中链甘油三酯对阿尔茨海默病影响的研究进展Progress in the impact of medium-chain triglyceride in Alzheimer′s disease
Zhongguo youzhi, 2023 为了研究中链甘油三酯（MCT）对延缓阿尔茨海默病（AD）发生的有效性，分析了MCT在体内的代谢过程，综述了MCT对AD的作用机制，介绍了MCT食品针对AD的应用状况。MCT可能通过抗氧化作用、抗炎作用、减少脑淀粉样蛋白-β沉积、保护线粒体功能以及改善脑能量代谢等方面延缓AD的发生。目前已有基于MCT的食品用于缓解AD患者的病情，如Axona（由MCT组成）、Ketonformula（基于MCT配方的奶粉）等。MCT对AD有一定的改善作用，在日常饮食中合理运用MCT可以延缓AD发生。In order ...

From caging to Rouse dynamics in polymer melts with intramolecular barriers: a critical test of the Mode Coupling Theory [PDF]
, 2010 By means of computer simulations and solution of the equations of the Mode Coupling Theory (MCT), we investigate the role of the intramolecular barriers on several dynamic aspects of non-entangled polymers. The investigated dynamic range extends from the

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)
Advanced Functional Materials, EarlyView.Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment
Advanced Functional Materials, EarlyView.Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...
