Laurent has conducted pioneering, internationally recognized research throughout his career on the chemistry of connective tissues, most notably on the physical and physiological properties, and medical applications of hyaluronan. He is currently Professor emeritus at this institution and Science Secretary for the Wenner-Gren Foundations, Stockholm. Laurent established a research program at the University of Uppsala, where he attained a Professorship in 1966. After a 3 year fellowship from the Retina Foundation in Boston, Dr. Torvard Laurent received his Doctor of Medicine from the Karolinska Institute, Stockholm in 1958.

Huachuan Du, Clemence Courrégelongue, Jacinta Xto, Alan Böhlen, Mathias Steinacher, Camelia N.Our findings suggest that the precise control of saturation levels is key in driving nucleation and crystallization. Once crystallization occurs, the magnesium calcites that form are stable in solution and exhibit slow growth through Ostwald ripening. The mechanism of formation is consistent with that observed during biomineralization, during which an intermediate magnesium-rich amorphous calcium carbonate (Mg-ACC) phase forms first and later transforms into high magnesium calcite. By varying the pH, cation-to-anion ratio, and solution concentration, the controlled synthesis of magnesium calcites with 10–45% magnesium was achieved at room temperature.

Herein, we present a systematic study on how to tune magnesium incorporation into calcite and polymorph selection in the Ca–Mg–CO 3 system through the precise control of the inorganic solutions chemistry at ambient conditions of temperature and pressure, and at a magnesium-to-calcium ratio of 5:1, which is analogous to the ratio found in most seas.

However, the replication of these processes in the laboratory is still challenging. The mechanistic understanding of how they achieve such exquisite control, at a constant magnesium-to-calcium ratio and at ambient conditions, is important in the development of bioinspired functional materials. Under ambient conditions, marine organisms are able to synthesize a variety of functional materials, ranging from eye lenses to protective shells through the meticulous control over magnesium incorporation into calcite during its crystallization.
