Structure and Spectroscopy of Criegee Intermediates in Gas‐ and Aqueous Environments

Helvetica Chimica Acta, Volume 109, Issue 5, May 2026.
ABSTRACT The dynamics and spectroscopy of the small (H2COO) and large (CH3CHOO) Criegee intermediates (CIs) in the gas phase, inside/on water droplets, on amorphous solid water (ASW) and in bulk water are investigated using validated energy functions.

Hydrogen Bonding Network in Interlayer Spaces of a Partially Deuterated Layered α‐Sn (IV) Phosphate: A Solid‐State MAS NMR Study

Magnetic Resonance in Chemistry, Volume 64, Issue 5, Page 521-527, May 2026.
The solid‐state 1H and 2H NMR data collected for deuterated α‐Sn (HPO4)2 phosphate suggest the hydrogen bonding network, where the cavity water accepts one hydrogen bond from the P‐OH donor group and forms one hydrogen bond with the neighboring phosphate group, while the other water hydrogen is not involved in hydrogen bonding.

Hydromagnesite Precipitation in an Ultramafic‐Hosted Alkaline Lake: Insights From Lake Salda for Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Lake Salda (SW Turkey) is one of the most compelling terrestrial analogs for Jezero Crater on Mars due to its highly alkaline, Mg‐rich waters and hydromagnesite‐forming microbialites. This study integrates hydrochemical measurements, saturation‐index modeling, SEM–TEM imaging, and X‐ray diffraction (XRD) analysis to disentangle the biotic and ...

Second‐Generation Crystalline Sponges Enabling Consistent Structure Analysis Under Standardized Conditions for Diverse Molecules

Angewandte Chemie, Volume 138, Issue 17, 20 April 2026.
The second‐generation crystalline sponge method allows structurally diverse molecular guests to crystallize under standardized crystallization conditions. The key is the predominant packing type of cages and anions in crystals. ABSTRACT Crystallization is typically highly sensitive to even minor structural differences in target molecules.

A robotic goniometer exchanger for high‐throughput single‐crystal X‐ray diffraction at SPring‐8

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 825-828, May 2026.
A compact six‐axis robotic arm has been implemented at the BL02B1 beamline of SPring‐8 as a high‐precision goniometer for single‐crystal diffraction. Its programmable control enables automated sample handling and centring, advancing autonomous high‐throughput diffraction in preparation for SPring‐8‐II.Rapid and reliable sample handling is essential for

Generation and modulation of catalytically relevant states of a dye‐decolourizing peroxidase using time‐resolved serial femtosecond crystallography with drop‐on‐chip mixing and X‐ray‐driven reduction

Acta Crystallographica Section D, Volume 82, Issue 5, Page 434-445, May 2026.
We characterize the formation of a ferryl state of a dye‐decolourizing peroxidase by drop‐on‐chip serial femtosecond crystallography and also the modulation of the heme redox state using dose‐resolved serial synchrotron crystallography.Metalloenzymes containing a heme cofactor catalyse a wide range of oxidative reactions critical to life. Understanding
