Hybridization of Homogeneous and Heterogeneous Catalysis to Develop a Novel Biocatalyst via Immobilization of Lipase on Surface Modified Mesoporous Silica Towards Biodiesel Synthesis Application

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
The 3‐(methacryloyloxy)propyltrimethoxysilane surface functionalized SBA‐15 (MP‐SBA‐15) is used for the first time as a lipase carrier. The immobilized CAL‐B exhibits high thermal stability and superior catalytic activity. CAL‐B/SBA‐15 suggests that optimum hydrophobicity gives better catalytic activity.

Effective acetalization of furfural catalyzed by Fe‐ and Co‐oxalates: impact of alcohols structure on products composition

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 703-716, March/April 2026.
Abstract Fe‐, Co‐, and FeCo‐oxalates supported on silica gel (5 wt% metal load) were synthesized, characterized, and tested for the first time in solvent‐free furfural (FF) acetalization with C1–C8 alcohols at 70–170 °C under both conventional and microwave (MW)‐assisted conditions. The interaction of FF with linear C1–C4 alcohols yielded pincer‐shaped

Rational Design and Functional Optimization of Surface‐Enhanced Raman Spectroscopy Substrates: From Material Engineering to Bioanalysis

ChemistryEurope, Volume 4, Issue 3, March 2026.
This review presents a rational design framework for high‐performance surface‐enhanced Raman spectroscopy (SERS) substrates enabling ultrasensitive detection. It first elucidates the dual enhancement mechanisms, namely the dominant electromagnetic enhancement arising from localized surface plasmon resonances and the complementary chemical enhancement ...

Drought‐driven lipid deficits in overwintering monarch butterflies revealed by δ2H and fatty acid analysis

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Eastern populations of monarch butterflies (Danaus plexippus) overwinter in the central trans‐volcanic belt of Mexico, relying primarily on lipids accumulated during migration to sustain this several‐month‐long overwintering period. This study shows how drought conditions in north‐central Mexico influenced lipid dynamics in monarchs ...

An Ensemble Machine Learning Method for Alkali‐Activated Concrete Mix Ratio Analysis and Optimizing Experimental Results

Engineering Reports, Volume 8, Issue 3, March 2026.
In this study, we discovered a combined learning algorithm of MLP–RF for predicting the composition of concrete and achieved favorable results in the inversion experiment. ABSTRACT In the field of civil engineering, the analysis of the composition of alkali‐sprayed concrete is of great significance for material research. However, there are currently no
