Exploring the Photophysical Processes of an Al3+ Sensor Based on Schiff Base
ChemPhysChem, EarlyView.Multiple excited‐state intramolecular proton transfer (ESIPT) processes and twisted intramolecular charge transfer (TICT) states are observed on the S1 state potential energy surface of an Al3+ sensor. The ESIPT process induces an ultrafast CC rotation process and leads to a non‐emissive TICT state.

Semi‐Automated Pipeline for Transition State Search of Molecular Photoswitches
ChemPhotoChem, EarlyView.A semi‐automated pipeline for the transition state search of molecular switches (PiTS3) is reported, which facilitates the search, optimization, and conformational analysis of transition states of photochemical switches based on the stilbene, imine, aza‐diarylethene, and norbornadiene structures.

The Depositional Record, EarlyView.The Bisperode section is one of the most expanded and complete sections with shallow‐marine Oxfordian strata in the LSB. This study provides a reference record for shallow‐marine settings and allows for the correlation of the strata from the LSB with Oxfordian deposits distributed elsewhere in the world.

European Journal of Organic Chemistry, EarlyView.Two C3‐symmetric organocatalysts with multiple amino groups are prepared and employed in the asymmetric addition of 4‐hydroxycoumarin and quinoline‐2‐one to unsaturated ketones. The all‐amino version of the catalyst induces the better stereoselectivity and provides the products in up to 95% yield.

A path to reconciliation between Indigenous and settler–colonial epistemologies
Frontiers in Ecology and the Environment, EarlyView.There is a movement across settler–colonial institutions of education and research to engage with Indigenous Peoples and Knowledges. Many settler and Indigenous governments are pursuing pathways to move forward together to address global problems such as climate change. However, given the pervasive history of exploitation and displacement of Indigenous

Error Analysis of a Pressure‐Correction Method With Explicit Time‐Stepping
International Journal for Numerical Methods in Fluids, EarlyView.We study explicit variants of this well‐established pressure‐correction scheme for solving the Navier–Stokes equations. Step 3 is replaced by an explicit time‐integration method. We give the complete error analysis for this scheme that allows for highly efficient implementations.

Potential Spectral Tuning of the Tapetum Lucidum in a Broadly Distributed Ungulate
Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT The tapetum lucidum, a biological reflector system found in the eyes of many vertebrate species, enhances visual sensitivity in low light conditions by reflecting light back through the retina. The structure of the ungulate tapetum fibrosum is unique, and its reflectance varies temporally in reindeer (Rangifer tarandus).
