Safeguarding the Photoluminescence of Silver Sulfide Nanocrystals in Biological Environments via Silica Shielding

Small, EarlyView.
Interactions with biomolecules can alter the photoluminescence of Ag2S nanocrystals, undermining near‐infrared imaging and thermometry. Incorporation into dendritic silica minimizes these interactions and preserves emission intensity, spectral response, and lifetime in plasma and whole blood. This shielding enables more reliable imaging and temperature

Downsize Effect on Photocatalytic Syngas Production of a 2D Metal Organic Framework—Tuning the Selectivity From HER to CO2RR via Dimensional Modulation and Mechanical Exfoliation of 2D Metal‐Organic Layers

Small Methods, EarlyView.
A cobalt(II) 2D MOF (2D) has been downsized by covalent bond breaking to form a 1D MOF (1D) and by sonication, to form a 2D exfoliated MOF (2D‐ex). Photocatalytic CO2 reduction shows that 2D and 1D lead to H2‐enriched syngas, whereas 2D‐ex leads to CO‐enriched syngas.

Nematicidal Activity of the Essential Oils from (Rutaceae) Samples

Natural Product Communications, 2006
The composition and nematicidal activity of the essential oils from the leaves of native and six cultivated varieties of P. microphyllus are reported. Twenty-nine compounds were identified (86.2% sesquiterpenes and 13.8% aliphatic ketones) of which (E ...

Salt Tectonics and Inversion Style in the Southeastern Iberian Chain

Tectonics, Volume 45, Issue 11, November 2026.
Abstract The southeastern Iberian Chain is characterized by Mesozoic rift basins that were subsequently inverted during Alpine contraction. We integrate geological mapping, borehole data, balanced cross‐sections, structural restoration, and forward kinematic modeling to evaluate how rift architecture controlled Alpine deformation from basin to crustal ...

POMs‐GibbsNet: A Deep Neural Network for the Prediction of Thermodynamic Parameters of Polyoxometalates

Journal of Computational Chemistry, Volume 47, Issue 28, October 30, 2026.
Polyoxometalate thermochemistry is often limited by the high cost of DFT vibrational frequency calculations. POMs‐GibbsNet uses molecular structure, electronic, and QTAIM descriptors to predict thermal Gibbs free‐energy corrections without calculating the Hessian.
