Menthol-Based (Deep) Eutectic Solvents: A Review on Properties and Application in Extraction.

In the last 10 years the interest in deep eutectic solvents (DESs) as a new class of green solvents has considerably increased. The emergence of numerous of hydrophobic DESs has stimulated intensive research into their application in extraction technologies, including sample preparation. As the properties of such systems are highly dependent on the properties of their components (hydrogen bond donors and acceptors) and can be finely tuned, DESs can be successfully used for the extraction of both metal ions and organic substances, including biomolecules.

Synthesis and Adsorption Properties of Gadolinium-Imprinted Divinylbenzene-Based Copolymers.

Ion-imprinted divinylbenzene and methacrylic acid copolymers for rare-earth element adsorption with crosslink ratios 60 and 40% have been synthesized. Ion imprinting has been carried out via the trapping approach. Alizarin red S has been incorporated in the polymers as a nonvinylated ligand.

Incongruent Melting La Y Sc(BO): LYSB Nonlinear Optical Crystal Grown by the Czochralski Method.

Nonlinear optical (NLO) crystals with incongruent melting of La Y Sc (BO) ( x + y + z = 4) (LYSB)-type were grown for the first time, to the best of our knowledge, by the Czochralski method. A special thermal assembly was used and the melt composition, growth direction, and the pulling and rotation rates have been optimized. Good optical quality LYSB crystal with a diameter of about 13 mm and a length of 25 mm has been grown from the LaYSc(BO) starting melt composition, along the c-axis direction, using a slow rotation rate of 8-10 rpm and a high pulling rate of 2 mm/h.
