High Thermoelectric Performance in Low‐Cost Cu8SiSxSe6‐x Argyrodite
Advanced Functional Materials, EarlyView.This study discovers the great potential of Cu8SiSxSe6‐x argyrodites as new, low‐cost, Te‐free thermoelectric materials. The proposed defect scheme suppresses the phase transition, enhances the weighted mobility and optimizes the grain boundary contacts.

Advanced Functional Materials, EarlyView.This study presents a novel donor‐bridge‐acceptor‐bridge‐donor (D‐B‐A‐B‐D) molecular system, which shows near‐unity intramolecular excitation energy transfer (IET) from two identical energy donors to a coplanar acceptor. It enables a four‐level energy system for efficient lasing at the acceptor emission band in a microspherical cavity with a low lasing

Stress and disorders of the stress system [PDF]
Nature Reviews Endocrinology, 2009 All organisms must maintain a complex dynamic equilibrium, or homeostasis, which is constantly challenged by internal or external adverse forces termed stressors. Stress occurs when homeostasis is threatened or perceived to be so; homeostasis is re-established by various physiological and behavioral adaptive responses.

Digestive Diseases and Sciences, 1989
The association between emotion and gastrointestinal dysfunction has been postulated for centuries, and all practicing clinicians have anecdotal experience of the association between stress and irritable bowel syndrome (IBS). However, definite proof of an etiologic link between stress and gut motor dysfunction remains elusive, despite the large number ...
