Unveiling Strain‐Driven Catalysis in Magnesium Hydride via Ultrafine High‐Entropy Hydride

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The unprecedented, direct, and tailored synthesis of high‐entropy hydride (HEH) nanoparticles is achieved under ambient conditions via one‐step mechanochemical strategy and demonstrates exceptional catalytic behaviors in magnesium hydride (MgH2) hydrogen storage, where partially dehydrogenated HEH introduces abundant lattice strain and hydrogen ...

Optical and Chiroptical Properties of a Green‐Emitting Tb(III) Complex Embedded in Silica Nanoparticles

European Journal of Inorganic Chemistry, EarlyView.
The SiO2 matrix improves the luminescence efficiency of the chiral Tb(bpcd)Cl complex by mitigating multiphonon relaxation, without compromising its chiroptical response. A spectroscopic investigation of water‐soluble and chiral Tb(III) complexes with N,N′‐bis(2‐pyridylmethyl)‐trans−1,2‐diaminocyclohexane‐N,N′‐diacetic acid, embedded in water ...

Synthesis of Flavones by Intramolecular O‐Arylation of Unactivated Halogenated Aryl‐1,3‐diketones

European Journal of Organic Chemistry, EarlyView.
A protocol for the synthesis of flavone derivatives starting from mono‐ and dihalogenated diketones including fluorinated derivatives in a very simple and effective way is reported. Flavones are an important class of secondary metabolites in plants. Here we report a straightforward method for the conversion of unactivated halogenated 1,3‐biaryl‐1,3 ...

Photocatalyst‐Free Trifluoromethylation of Indolizines Through an Electron Donor–Acceptor Complex

European Journal of Organic Chemistry, EarlyView.
A new photocatalyst‐free pathway for the direct C‐3‐trifluoromethylation of indolizines and imidazo[1,2‐a]pyridines through an electron donor–acceptor (EDA) complex is studied. This regioselective reaction supports a wide range of functional groups, indicating good versatility and robustness.

Effects of hybrid metal oxide nanoparticles on the tribological and emission attributes of algae‐derived biofuel in compression ignition engines

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The growing demand for sustainable fuels has accelerated the development of algae‐derived biodiesel for compression‐ignition engines. In this study, Chlorella vulgaris methyl ester (AME) exhibited physicochemical properties comparable to diesel and satisfied ASTM D6751 fuel quality requirements, making it suitable for blending.
