Computational Crystallization [PDF]
Archives of Biochemistry and Biophysics, 2015 Crystallization is a key step in macromolecular structure determination by crystallography. While a robust theoretical treatment of the process is available, due to the complexity of the system, the experimental process is still largely one of trial and ...

Enhancement of Crystallization Process of the Organic Pharmaceutical Molecules through High Pressure
Crystals, 2022 The enhancement of the crystallization process through high pressures was studied by using ribavirin (RVB) as a model compound. The effects of high pressure on crystallization thermodynamics, nucleation kinetics, and process yield were evaluated and ...

Molecular tectonics: from crystals to crystals of crystals [PDF]
Chemical Communications, 2013 The in situ combination of M(II) cations (Co, Ni, Cu or Zn) with 2,4,6-pyridinetricarboxylic acid as a ligand, a bisamidinium dication as a H-bond donor tecton and NaOH leads to the formation of anionic metal complexes ML2(2-) and their interconnection into isomorphous 3D H-bonded networks displaying different colours which were used as preformed seed ...

Gypsum Seeding to Prevent Scaling
Crystals, 2022 Eutectic freeze crystallization (EFC) is a novel separation technique that can be applied to treat brine solutions such as reverse osmosis retentates. These are often a mixture of different inorganic solutes. The treatment of calcium sulphate-rich brines
