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 ...

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

Variability of surface solar irradiance and aerosol optical depth during partial solar eclipse of January 4, 2011 in Kishinev, Moldova

Moldavian Journal of the Physical Sciences, 2011
Variation of surface solar irradiance and aerosol optical depth (AOD) during the partial solar eclipse on January 4, 2011 is analyzed on the basis of the ground observations at the Kishinev (Chisinau) site.

Pattern and variation of electron ionisation gradient as related to the plasma distribution mechanisms during the total solar eclipse of March 20, 2015

Journal of Nigerian Society of Physical Sciences
The pattern and electron ionisation gradient associated with the obstruction of solar ionizing radiation (SIR) provided a good opportunity to study the plasma movements and neutral compositions during the solar eclipse at mid-latitude.

The ionospheric responses to the 11 August 1999 solar eclipse: observations and modeling [PDF]

Annales Geophysicae, 2008
A total eclipse occurred on 11 August 1999 with its path of totality passing over central Europe in the latitude range 40°–50° N. The ionospheric responses to this eclipse were measured by a wide ionosonde network.

Analysis of penumbral eclipse data [PDF]

, 1977
Two days of data from the ATS-6 1976 eclipse season were analyzed to determine the effects of varying photoelectron flux on spacecraft potential. Particular emphasis was placed on the variation in potential as the satellite entered the earth's penumbra ...

Identification of Absorption Features in an Extrasolar Planet Atmosphere

, 2007
Water absorption is identified in the atmosphere of HD209458b by comparing models for the planet's transmitted spectrum to recent, multi-wavelength, eclipse-depth measurements (from 0.3 to 1 microns) published by Knutson et al. (2007). A cloud-free model

Atmospheric Gravity Waves Observed in the Nightglow Following the 21 August 2017 Total Solar Eclipse

Geophysical Research Letters, 2020
Nighttime airglow images observed at the low‐latitude site of São João do Cariri (7.4°S, 36.5°W) showed the presence of a medium‐scale atmospheric gravity wave (AGW) associated with the 21 August 2017 total solar eclipse.

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.
