Sustainable levulinic acid production from inulin via hydrothermal conversion
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study investigates the hydrothermal conversion of inulin using potassium pyrosulfate to levulinic acid (LA). The Box–Behnken design approach was applied to optimize the conversion parameters and analyze the interactions influencing LA yield.

British Journal of Clinical Pharmacology, EarlyView.Abstract Aim Besides registries, healthcare databases can provide useful information for assessing the frequency of major congenital malformations (MCMs) and investigating their risk factors, particularly medication exposures. This study aimed to assess the validity of MCMs identification based on French national, comprehensive healthcare databases ...

Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine
Chemistry – A European Journal, EarlyView.Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...

Influence of functional silanes on hydrophobicity of MCM-41 synthesized from rice husk
Science and Technology of Advanced Materials, 2007 Mesoporous molecular sieve MCM-41 was synthesized from rice husk and rice husk ash, called RH-MCM-41 and RHA-MCM-41. The sol–gel mixtures were prepared with molar composition of 1.0 SiO2: 1.1 NaOH: 0.13 CTAB: 0.12 H2O.
