The Influence of Ni Content in NixCoy‐BDC Metal‐Organic Frameworks on Catalytic Activity for Hydrogen Generation from Sodium Borohydride

open access: yesChemCatChem, Volume 18, Issue 11, 15 June 2026.
ABSTRACT Mono‐ and bimetallic Ni/Co‐based metal–organic frameworks (MOFs) coordinated with 1,4‐benzenedicarboxylate were successfully synthesized via a solvothermal approach and characterized by PXRD, FTIR, TGA, SEM–EDS, TEM, BET, and XPS. Fine control over the Ni:Co molar ratio enabled systematic modulation of the structural and electronic properties ...

Roasting‐Like Thermal Reconfiguration of Bioactive and Pigment Profiles in Pistachios From Distinct Geographical Origins

open access: yesFood Science &Nutrition, Volume 14, Issue 6, June 2026.
Dry roasting‐like treatment (140°C for 45 min) induces a significant compositional reconfiguration of (poly)phenols, pigments, and antioxidant capacity in pistachio kernels, strictly dependent on their geographical origin (Iran, Spain, USA, and Turkey), ultimately enhancing their functional quality.

Laser Sintering and Optical Characterization of LuAG: Ce Ceramics

open access: yesphysica status solidi (b), Volume 263, Issue 6, June 2026.
Additive‐free densification of LuAG:Ce ceramics is achieved via CO2 laser sintering within seconds, producing high‐density and homogeneous microstructures compared to conventional processing. However, laser‐sintered samples exhibit enhanced oxygen vacancy concentrations, leading to reduced photoluminescence intensity and a red shift in emission.

Effect of Cell Disruption and Protein Extraction on the Structural and Technological Properties of Tetradesmus obliquus Protein‐Rich Extracts

open access: yesSustainable Food Proteins, Volume 4, Issue 2, June 2026.
Despite its considerable potential as a functional food ingredient, T. obliquus faces a major limitation in protein recovery due to the rigidity of its cell wall. In the microalgae industry, protein extraction typically involves two main steps: cell disruption and protein extraction.

Inter–Annual Variability of Model Parameters Improves Simulation of Annual Gross Primary Production

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract Parametric uncertainty can hinder land surface models (LSM) from accurately simulating carbon fluxes, such as gross primary production (GPP). These models generally cannot capture inter–annual variability (IAV) of fluxes well due to missing processes, and temporally varying parameters can partially alleviate this limitation.
