A simple and practical approach for protein serial crystallography using grease matrix and large‐area support film

Journal of Synchrotron Radiation, EarlyView.
A simple fixed‐target protein serial crystallography method combining a grease matrix with a large‐area support film enables stable sample handling, low sample consumption, and high‐resolution room‐temperature structure determination.Serial femtosecond crystallography (SFX) enables structural determination of biological macromolecules at room ...

Characterization of Nanocrystals of Eu-Doped GaN Powders Obtained via Pyrolysis, Followed by Their Nitridation

Photonics
Nanocrystals of Eu-doped GaN powders are produced via pyrolysis of a viscous compound made from europium and gallium nitrates. Furthermore, carbohydrazide is used as a fuel and toluene as a solvent; subsequently, a crucial nitridation process is carried ...

Glass from Teniky (Madagascar): Geochemical Evidence for Multiple Production Systems and Long‐Distance Exchange in the Mediaeval Indian Ocean

Archaeometry, EarlyView.
ABSTRACT The inland rock‐cut site of Teniky, located in the Isalo massif of southern Madagascar, represents an exceptional archaeological context recently dated to the 11th–12th centuries ad, corresponding to the early phases of settlement on the island.

Defining the role of αC helix interactions in the activation of the integrin αI domain

The FEBS Journal, EarlyView.
The α2I domain of the α2β1 integrin contains a distinctive αC helix and a conserved Arg288‐Glu318 ion pair that stabilizes the closed state of the domain. Disruption of this ion pair in the activated α2I variant unwinds the αC helix, which allows interaction with additional collagen‐binding sites increasing collagen binding.

Europium Tricyclopentadienide

Zeitschrift für Naturforschung B, 1966
Europium tricyclopentadienide has been prepared by the reaction of dichloroeuropium cyclopentadienide with two equivalents of sodium dicyclopentadienide as well as by the reaction of europium trichloride with three equivalents of sodium cyclopentadienide, both reactions taking place in tetrahydrofuran. It is stable in vacuum at temperatures up to 70°C.

An Integrative Approach Toward Bio‐Inspired Sequestration of Rare Earth Elements

ChemSusChem, Volume 19, Issue 16, 27 August 2026.
The binding behavior of EF‐hand 4 of calmodulin toward different lanthanide ions was studied using a combination of spectroscopic and computational methods. A resin‐immobilized peptide demonstrated its potential as a selective and sustainable filter material for lanthanide separation.Lanthanides (Ln) are essential for renewable energy technologies, yet

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, Volume 20, Issue 8, Page 1933-1962, August 2026.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
