Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...

Pt‐TiO2 mesoporous nanosystem co‐delivering phlorezin enables synergistic sonodynamic‐chemoimmunotherapy for hepatocellular carcinoma via directly targeting DDX5 and metabolic reprogramming modulation

BMEMat, EarlyView.
Abstract Hepatocellular carcinoma (HCC), ranking as the third leading cause of cancer‐related mortality globally, continues to pose significant therapeutic challenges. Here, we developed an innovative nanosystem, Phl@PT, based on Pt‐TiO2 nanoparticles for the co‐delivery of Phlorezin, presenting a novel approach for HCC treatment through sonodynamic ...

Self‐Immolative Gels: Programmable Degradation Using Self‐Immolative Linkers and Polymers

Chemistry – A European Journal, EarlyView.
Self‐immolative linkers and polymers undergo bond‐cleaving reaction cascades in response to specific stimuli. Their incorporation into gels can be harnessed to release cargo, induce property changes, or trigger degradation in a highly controlled manner. These functions can be employed in applications such as sensing and drug delivery.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.
