Angewandte Chemie International Edition, EarlyView.An improved low‐temperature synthesis enables the first comprehensive structural and spectroscopic characterisation of neutral hexacyanotrimethylenecyclopropane (CN6CP). Combined IR/Raman, UV–Vis and ssNMR analyses reveal a deeper understanding of its oxidation‐state‐dependent charge redistribution, σ‐aromaticity of the cyclopropane core, and redox ...

Role of Water in Low‐Temperature CO2 Reduction at Defect‐Rich TiO2
Angewandte Chemie International Edition, EarlyView.Our results highlight the potential of reduced titania as a noble metal‐free CO2 activation catalyst and show the activation of CO2 on highly defective TiO2 using in situ synchrotron‐based NAP‐XPS from room temperature to 700 K. The distribution of surface intermediates can be decoded as a simultaneous population of reaction routes, revealing water (OH)

Journal of Applied Polymer Science, EarlyView.Antistatic performance in HDPE/conductive carbon black composites is governed not only by filler structure but also by processing. Injection molding induces surface resistivity through skin–core effects, whereas compression molding favors conductive networks.

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review
Advanced Physics Research, EarlyView.Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.

Moiré Folded Helical States at the Interfaces of Heterostructures
Advanced Physics Research, EarlyView.This manuscript explores a minimal ladder model of a graphene‐topological‐insulator heterostructure where moiré superlattices modulate Rashba spin‐orbit coupling. The study reveals that SOC lifs spin degeneracy, halves spectral periodicity, and induces “helicity fragmentation” across moiré minibands.

Nanoscale Thermal Transport in Bi2(Te, Se)3 Thermoelectric Material Using Pulsed STEM
Advanced Physics Research, EarlyView.The pulsed‐STEM technique enables simultaneous acquisition of crystallographic, compositional, and thermal transport information within a single experiment. In anisotropic Bi2(Te, Se)3, phase‐delay imaging visualizes directional heat flow and interfacial resistance at the nanoscale, offering a new approach to understanding and designing thermoelectric ...

Solvation Effects on Quantum Tunneling Reactions.
Accounts of Chemical Research, 2022ConspectusA decisive factor for obtaining high yields and selectivities in organic synthesis is the choice of the proper solvent. Solvent selection is often guided by the intuitive understanding of transition state-solvent interactions.
