Ionic liquid-H2O2 propellants and their ignition behavior

Propulsion and Energy
As the primary power source, propellants enable faster and more distant space exploration. While the traditional hydrazine-based bipropellants are gradually replaced due to their extreme volatility and carcinogenicity, ionic liquid-H2O2 has become an ...

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Risk assessment using IEUBK model for the Naica mine tailings

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Mexico has a long history of mineral extraction, during which limited environmental regulations allowed the accumulation of toxic waste near communities, primarily in rural or undeveloped areas. Some of these toxic substances, such as lead, pose significant risks to vulnerable populations, particularly children aged 0 to 7 years.
