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 ...

Advanced Energy Materials, EarlyView.This study provides mechanistic insights into ionic conduction in lead halide perovskites (LHPs) and perovskite‐inspired materials (PIMs). By comparing ionic conduction in PIMs with the well‐studied LHPs, correlations are established between ionic transport, anomalous device kinetics, and operational stability.

The IAU and Solar Eclipses [PDF]
Proceedings of the International Astronomical Union, 2018 AbstractWe describe the history of solar-eclipse supervision since the formation of the International Astronomical Union, as the supervising body morphed from a full commission to a subcommission to its current status as an Inter-Divisional Working Group of the Education, Outreach and Heritage Division and the Sun and Heliosphere Division.

The solar eclipse and its relation with higree months
Iraqi Journal of Physics, 2019 The solar eclipse occurs at short time before the crescent birth moment when the moon near any one of moon orbit nodes It is important to determine the synchronic month which is used to find Higree date.

Ionospheric responses on the 21 August 2017 solar eclipse by using three-dimensional GNSS tomography
Earth, Planets and Space, 2022 In this study, we have investigated the ionospheric responses on the August 2017 solar eclipse event by using a three-dimensional tomography algorithm with the ground-based GNSS (Global Navigation Satellite System) total electron content observations ...

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

Astronomische Nachrichten, EarlyView.ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$
