• Simulated Moving Bed Chromatography: from chiral molecules to biocompounds
  

  The Simulated moving bed (SMB) technology was developed in the '60s and used for large-scale separations of hydrocarbons in the oil industry. The SMB concept has been extended towards new fields of application since then, first in the large-scale food industry, e.g. separation of sugars, and lately in the separation of fine chemicals, particularly chiral molecules where it is now an established technique more

• Separation of Nadolol Stereoisomers by Chiral Liquid Chromatography at Analytical and Preparative Scales

  ABSTRACT The separation of the four nadolol stereoisomers on Chiralpak® AD by chiral liquid chromatography was carried out at both analytical and preparative scales. A screening of possible mobile‐phase compositions was performed using different alcohol–hydrocarbon mixtures. The results obtained more

• ChemInform Abstract: Additive‐Assisted Synthesis of Boride, Carbide, and Nitride Micro/Nanocrystals.

  Abstract A series of boride (TiB2, ZrB2, NbB2, CeB6, PrB6, SmB6, EuB6, LaB6), carbide (SiC, TiC, NbC, WC), and nitride (TiN, BN, AlN, MgSiN2, VN) micro/nanocrystals are prepared from the corresponding metal oxides and amorphous boron/active carbon/NaN3 in the presence of metallic Na and elementa more

• Identification of novel penta- and hexamethylated branched glycerol dialkyl glycerol tetraethers in peat using HPLC-MS2, GC-MS and GC-SMB-MS

  A Siberian peat contains a high abundance of three unknown isomers of hexamethylated branched (br) GDGTs, of which two are present as a second peak eluting shortly after the known hexamethyl br GDGT containing two 5,13,16-trimethyloctacosanyl moieties. Tandem high performance liquid chromatography- more
