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

Journal 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

Journal 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 ...

Detection of Acoustic Phonons in Carbon by Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Acoustic phonons in graphite and diamond are detected by Raman spectroscopy through disorder‐induced relaxation of selection rules. Comparison with calculated phonon densities of states enables assignment of the observed Raman features to acoustic phonon branches.

Structure and Dynamics of Ultra‐Low‐Crosslinked Microgels

Journal of Polymer Science, EarlyView.
This study reveals the relationship between microgel internal architecture, zero‐shear viscosity, structural relaxation time, and the ability of ultra‐soft colloidal suspensions to remain viscous fluids under overcrowded conditions. This interplay between microgel compressibility and zero‐shear viscosity is further highlighted by a colloid‐polymer ...

Safety, efficacy, pharmacokinetics, and mechanisms of novel 10B‐boronophenylalanine combined with a radio‐frequency quadrupole accelerator in boron neutron capture therapy: A preclinical study in head and neck squamous cell carcinoma

Precision Radiation Oncology, EarlyView.
This study demonstrates that the novel 10B‐BPA‐based BNCT system, combined with an RFQ accelerator, effectively targets head and neck squamous cell carcinoma. It induces tumor regression safely and efficiently by triggering DNA damage and activating the ROS/HIF‐1α/NF‐κB pathway, leading to caspase‐3‐mediated apoptosis.
