Memory of Chirality in Radical Addition–Translocation–Cyclization Cascades

open access: yesHelvetica Chimica Acta, EarlyView.
Radical addition–translocation–cyclization cascades of chiral alkynes show striking memory of chirality (MoC), with strong retention of configuration when fast, polarity favored cyclization are involved. The most effective system employs a highly electron‐poor pentafluorobenzenesulfonyl group.

Mapping the Adolescent Mind: Profiles of Reflective Functioning and Epistemic Trust in Adolescent Psychopathology

open access: yesJournal of Adolescence, EarlyView.
ABSTRACT Introduction Adolescence is a period of heightened vulnerability to psychopathology, when capacities for mentalising and interpersonal trust develop rapidly. This study investigated how configurations of reflective functioning (RF) and epistemic trust (ET) differentiate patterns of internalizing and externalizing problems in youth.

Role of High Fidelity Vs. Low Fidelity Experimental Data in Machine Learning Model Performance for Predicting Polymer Solubility

open access: yesMacromolecular Rapid Communications, EarlyView.
The performance of machine learning models for classifying polymer solubility improves when a high‐fidelity experimental dataset is used compared to a low‐fidelity experimental dataset. This has important implications for justifying the value of spending additional time and resources preparing detailed experimental datasets.

Metathesis‐Sourced Epoxides in Ring‐Opening Copolymerization: Selective Access to Degradable Polythioesters

open access: yesMacromolecular Rapid Communications, EarlyView.
Metathesis‐derived cyclopentene epoxides enable strictly alternating, scrambling‐free ring‐opening copolymerization with phthalic thioanhydride, yielding well‐defined polythioesters with molecular weights up to ∼38 kg/mol. Their performance extends to oxygen‐based anhydrides and selective terpolymerizations. Direct comparisons with all‐oxygen analogues

A PLP‐SEC Investigation of Di(Ethylene Glycol) Methyl Ether Methacrylate Radical Polymerization Propagation Kinetics in Solution

open access: yesMacromolecular Reaction Engineering, EarlyView.
The propagation rate coefficient of di(ethylene glycol) methyl ether methacrylate exhibits the same temperature dependency but is a factor of 12 higher in aqueous solution compared to bulk. Smaller increases are observed in ethanol and ethanol/water mixtures, with the value of the rate coefficient decreasing as the monomer concentration in solution is ...

A green solvent processable, self‐doped N‐annulated perylene butyl tetraester applied as a solar cell cathode interlayer

open access: yesPolymer International, EarlyView.
A new organic molecular cathode interlayer is presented built upon the perylene butyl tetraester scaffold. The new molecule incorporates N‐annulation and a functional amine group to control optical, electrochemical and physical properties and delivers excellent solar cell performance. Abstract We report a new amino‐bay‐substituted, N‐annulated perylene

Tape Casting of LLZO Ceramic Separators: An Overview of Challenges, Optimization Strategies, and Paths to Industrial Implementation. [PDF]

open access: yesChemSusChem
Tape casting is a cost‐effective process for the scalable and continuous production of thin layers from ceramic powders. In recent years, interest in the use of tape casting for the production of solid‐state battery components such as ceramic separators, ceramic cathodes, or complete cells has grown significantly.

Nickel Foam Electrodes—A Versatile, Powerful, and Readily Available Tool in Electro‐Organic Synthesis

open access: yesThe Chemical Record, EarlyView.
Nickel foam—one material, two faces, and several versatile roles depending on electrolytic conditions. For more than 50 years, nickel foam electrodes have served in electrosynthesis as powerful and readily available electrode materials. Due to their inexpensive nature and easy handling, they have been widely employed.
