Crystals as Rockets: Modulation of the Salient Temperature in Cocrystals by Solvent Mixture Composition. [PDF]

Angew Chem Int Ed Engl
Compositionally engineered mixed solvated cocrystals enable modulation of thermosalient actuation. Guest ratio controls thermosalient temperature and propulsion intensity, providing a tunable platform for designing crystalline systems that exhibit stimuli‐responsive mechanical motion.

Crystal structure and functional characterization of an Asp49 phospholipase A₂ from the bushmaster (Lachesis muta). [PDF]

Acta Crystallogr F Struct Biol Commun
The crystal structure of an Asp49 phospholipase A2 from L. muta is reported, revealing a tetrameric assembly, catalytic conservation and a polarized electrostatic surface potentially linked to membrane targeting.Snake‐venom phospholipases A2 (PLA2s) are small, structurally conserved enzymes that contribute significantly to the pathophysiology of ...

Double Salts and Racemate in Mefloquine-Ibuprofen and Mefloquine-Ketoprofen Systems. A Structural and Thermochemical Analysis. [PDF]

Chirality
(S)‐ibuprofen or ketoprofen were used to resolve mefloquine, forming double salts structurally similar to the racemic forms. ABSTRACT The formation of salts remains a highly sought‐after yet unpredictable strategy for resolving chiral drugs. Using a drug–drug approach, we have investigated the crystallization behavior of Mefloquine (Mf), a racemic ...

Bottom-Up Synthesis of Metallic CoNi Nanoplatelets with Magnetic Vortex-Like Spin Configurations. [PDF]

Small Sci
The study presents the topotactic reduction of CoNi hydroxide nanoplatelets into metallic CoNi nanoplatelets with diameters of around 1 μm using a scalable bottom‐up approach. Their resulting high magnetization and magnetic vortex remanent state unlock exciting potential for advanced biomedical applications, including targeted diagnostics and therapy ...

Late Cretaceous‐Recent Tectonostratigraphic Evolution of the Yucatan Back‐Arc Basin, Northern Caribbean Sea

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 8, August 2023., 2023
Abstract The 110,000 km2 Yucatan Basin in the northern Caribbean Sea is critical for understanding the Late Cretaceous to Recent tectonic evolution of the Caribbean‐North American plate boundary. This study integrates gravity, magnetic, and a 5,500 km grid of 2D seismic data to carry out a tectonostratigraphic analysis of the Yucatan Basin.
