Boosting the Photoluminescence of Au@Cu12 Nanoclusters via Strategic Fluorine‐Atom Ligand‐Shell Engineering

open access: yesJournal of the Chinese Chemical Society, EarlyView.
The photophysical performance of gold‐doped copper‐rich nanoclusters can be tuned by surface functionalization. Subtle ligand modification enhances intermolecular interactions, thereby reducing nonradiative decay and markedly improving photoluminescence. Comparative photographs and quantum yield values (Φ = 55% vs.

A Personal Perspective on Metalloprotein Structure and the Future of Macromolecular X‐Ray Crystallography

open access: yesJournal of the Chinese Chemical Society, EarlyView.
While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?

Decoupling glacier retreat and surface stabilization on the Snežnik Plateau (Slovenia), insights from in situ cosmogenic 36Cl exposure and depth‐profile ages

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

open access: yesJournal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

Comparative Evaluation of Large Amplitude Oscillatory Shear (LAOS) Analysis Methods for Detecting Surfactant‐Induced Structural Evolution in Xanthan Gum Solutions

open access: yesJournal of Polymer Science, EarlyView.
A comparative large‐amplitude oscillatory shear analysis reveals how cationic surfactants progressively weaken xanthan gum networks. While conventional rheology identifies network softening, advanced LAOS methods uncover nonlinear deformation mechanisms and transient structural evolution that remain hidden in cycle‐averaged measurements.
