Thermophysical properties of binary mixtures of N,N-dimethylformamide with three cyclic ethers [PDF]
Densities and viscosities of the binary mixtures consisting of tetrahydrofuran (THF), 1,3-dioxolane (1,3-DO) and 1,4-dioxane (1,4-DO) with N,N-dimethylformamide (DMF) over the entire range of composition were measured at temperatures 298.15, 308.15 ...

Identification and quantitation of lipid-bound short-chain diols
Procedures are described for the hydrolysis of neutral lipid fractions containing long-chain esters and alk-1-enyl ethers of short-chain diols, and for the identification and quantitation of the constituent diols as long-chain cyclic acetals using gas ...

This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion

Amphiphilic Polyfluorinated Amino Ethers from Cyclic Sulfamidates
Regioselective ring opening of cyclic sulfamidates was achieved by means of nucleophilic polyfluorinated alkoxides to access achiral and chiral β- and γ-ORF amines and α-amino esters. Subsequent transformations provide free amines ready for incorporation into bioactive substances through amide bond formation or nucleophilic aromatic substitution.
