Protein‐Independent Liquid–Liquid Phase Separation of Adenosine Triphosphate Under Crowded Conditions

open access: yesChemistry – A European Journal, EarlyView.
ATP itself is able to undergo liquid–liquid phase separation in the presence of the macromolecular crowding agent PEG and physiological ATP concentrations are sufficient for phase separation in the presence of mM Mg2+ and crowders, mimicking intracellular conditions.

Single-molecule identification of the entropy/enthalpy contributions in macromolecule crowding induced by Carboxylated chitosan

open access: yesPolymer Testing
Macromolecular crowding effects frequently drive phase separation and have a significant impact on a series of biochemical processes in the cell. Owing to the significant differences in the physical mechanisms of the macromolecular crowding effects ...

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

open access: yesJournal of Raman Spectroscopy, EarlyView.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Hybrid Quatsome‐Encapsulated Silver Nanoparticles as Stable Plasmonic Substrates for Surface‐Enhanced Raman Scattering

open access: yesJournal of Raman Spectroscopy, EarlyView.
In this work, silver nanoparticles encapsulated within quatsome membranes have shown to preserve their plasmonic properties for at least 165 days without aggregation. These hybrid nanostructures enable strong SERS enhancement of pyrene and Prodan by confining the molecules within a few nanometers from the silver surface.

High‐Temporal‐Resolution Monitoring of Creatine and Phosphocreatine Dynamics in Skeletal Muscle Using Ultrafast Z‐Spectroscopy (UFZ) CEST MRI at 3T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate the feasibility of High‐Temporal‐Resolution (HTR) Ultrafast Z‐spectrum (UFZ) CEST MRI for monitoring the dynamic fluctuations of phosphocreatine (PCr) and creatine (Cr) in human skeletal muscle (SM) at 3 T during and after exercise.

Supramolecular Surface Functionalization of Single‐Walled Carbon Nanotubes With Conjugated Graft Copolymers

open access: yesJournal of Polymer Science, EarlyView.
Post‐polymerization modification of poly(tetrazine‐co‐fluorene) conjugated polymer via an inverse‐electron‐demand Diels‐Alder reaction (IEDDA) introduces hydroxyl initiators that enable surface‐initiated ring‐opening polymerization (ROP) of lactide.

Generalizing the Gaussian Network Model: Spanning‐Tree Thermodynamics Shows Entropy‐Driven KRAS Activation

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The GTPase KRAS executes a conformational switch between a GTP‐bound active state and a GDP‐bound inactive state, a process central to oncogenic signaling. However, the structural basis of this switching at the level of residue‐contact organization remains incompletely characterized by traditional binary structural models.
