Calcium carbonate is an important component in exoskeletons of many organisms. The synthesis of calcium carbonate was performed by mixing dimethyl carbonate and an aqueous solution of calcium chloride dihydrate. The precipitation product was characterized by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier transform infrar...

LaNi4.4Sn0.25 and graphite powder disk electrodes sandwiched between two nickel screens were used as working electrodes in 6.0 M KOH and in 1.0 M LiPF6 in propylene carbonate-ethylene carbonate-dimethyl carbonate ~1:1:3! solution, respectively. Different electrochemical impedance spectroscopy protocols were used for analysis of the kinetics of insertion and extraction of hydrogen and lithium in...

The influence of egg white lysozyme on the size, shape, crystallography, and chemical composition of amorphous calcium carbonate (ACC) particles obtained from aqueous CaCl2-dimethyl carbonate (DMC)-NaOH solutions was studied. At the onset of precipitation, the presence of lysozyme led to much smaller particles (50-400 nm spherical amorphous lysozyme-calcium carbonate particles (Ly-ACC)) than th...

PNIPAM-b-PVDF amphiphilic block copolymers were synthesized via RAFT polymerization in dimethyl carbonate. These able to self-assemble into various morphologies such as spherical, crumpled, lamellar and lenticular 2D aggregates.

A simple procedure for the one-pot synthesis of 2,5-furandicarboxylic acid dimethyl ester (FDME) from galactaric (mucic) via carbonate (DMC) chemistry is presented. The compound was isolated as a white powder in 70% yield.

Abstract N -Methylated derivatives of α-tocopheramine, which have preliminarily been shown to good performance as stabilizers cellulose solutions in ionic liquids for production cellulosic manmade fibers, not accessible sufficient amounts by green syntheses. In this study, the -methyl-, , -dimethyl-, and -trimethylammonium α-tocopheramine were synthesized fully analytically characterized. The p...
