Resistive Heating for Inducing Localized Crystal Growth in Organic Thin Film Devices

Advanced Materials Technologies, EarlyView.
Rubrene thin films are promising for organic optoelectronics due to high hole mobility. However, uncontrolled crystallization and grain boundaries from standard thermal processing hinder lateral device scalability. This work presents femtosecond‐laser micromachining and patterned resistive heating to induce localized, deterministic crystallization ...

Solar eclipse effects of 22 July 2009 on Sporadic-E [PDF]

Annales Geophysicae, 2010
The total solar eclipse of 22 July 2009, was visible from some regions of China and the intense sporadic-E (Es) that broke out during the solar eclipse period over the eastern China provided a unique chance to study solar eclipse effects on the Es ...

The Gut Microbiota Regulates Motor Deficits via Butyrate in a Gnal+/− Mouse Model of DYT25 Dystonia

Advanced Science, EarlyView.
The present study provides compelling evidence for a modulatory role of the gut microbiota in the pathology of DYT25 dystonia, and butyrate supplementation alleviates the motor deficits of dystonia in Gnal+/− mice. Abstract Dystonia is the third most common movement disorder, following essential tremor and Parkinson's disease. The underlying mechanisms

An Efficient CO2‐Upcycling Platform Based on Engineered Halomonas TD with Enhanced Acetate‐Utilizing Capacity via Adaptive Laboratory Evolution

Advanced Science, EarlyView.
An electrochemical system is designed to convert CO2 into CO2‐derived electrolytes (CDE), mainly containing acetate and formate. The underlying mechanism of acetate metabolism in Halomonas TD80 is explored via ALE. Engineered TD80 produced high‐yield diversified products from CDE.

Defect Engineering Activates Pyrene‐Based Covalent Organic Frameworks for Efficient Photocatalytic Uranium Capture

Advanced Science, EarlyView.
A defect‐engineered pyrene‐based covalent organic framework (TP‐PYTO‐SA) is developed via strategic salicylaldehyde incorporation. This approach simultaneously enhances hydrophilicity and introduces uranyl coordination sites, while optimized defect density significantly improves charge separation.

The Effect of Pore Functionality in Multicomponent Covalent Organic Frameworks on Stable Long‐Term Photocatalytic H2 Production

Advanced Energy Materials, EarlyView.
Five COFs are synthesized through a multicomponent reaction, preserving a similar backbone while introducing varying pore functionalities. All COFs demonstrate excellent chemical stability and sustained H2 production under sunlight for 7‐15 days. The imidazole‐functionalized COF exhibits the highest H2 production, which can be attributed to its high ...

The centre-to-limb variations of solar Fraunhofer lines imprinted upon lunar eclipse spectra - Implications for exoplanet transit observations

, 2015
The atmospheres of exoplanets are commonly studied by observing the transit of the planet passing in front of its parent star. The obscuration of part of the stellar disk during a transit will reveal aspects of its surface structure resulting from ...
