Abstract
• The first low-toxicity cryoprotector for biomaterials is proposed and tested. • Glass formation in the Mg(CH 3 COO) 2 –(CH 3 ) 2 SO–H 2 O system is discovered. • Mg 2+ ions, CH 3 COO − ions, and water molecules play the key role in glass formation. • Structures of H-bonded polymer chains and solutions obey the same laws. • Factors responsible for the crystallization resistance of solutions are elucidated. Glass formation in the Mg(CH 3 COO) 2 –(CH 3 ) 2 SO–H 2 O system is found to occur and studied by calorimetry, IR spectroscopy, and density functional theory calculations. Experimental and quantum-chemical data are analyzed jointly in terms of the previously recognized structure-formation laws in aqueous and nonaqueous solutions. The first low-toxicity cryoprotector is developed and tested. The structure and energy parameters of polymer chains are determined in three glass-forming compositions of the Mg(CH 3 COO) 2 –(CH 3 ) 2 SO–H 2 O system. The structure of these chains, which are built of magnesium hexasolvates linked via CH 3 COO − ions and water molecules, is found to obey the structure formation laws that operate in solutions. Competition among (CH 3 ) 2 SO, H 2 O, and CH 3 COO − species for entering the first coordination sphere of Mg 2+ is studied. The hydrogen-bonded crystallization-resistant glasses are found to differ from crystallization-liable glasses by higher specific linking strengths (referred to the unit weight) of polymer-chain units.
