ABSTRACT. A revised value for the heat of formation of nitrate ion has been obtained by re-evaluating the lattice energy of cesium nitrate with consideration of charge distribution in the anion. With the revised value for ΔHƒ (NO3-) the Born-Haber cycle yields a lattice energy of —157 kcal./mole for nitrogen pentoxide.

RSC Advances publishes advances in chemistry, and in topics of interest to the chemistry community. Thoughts from our Editor-in-chief "Scientific publishing is entering an exciting period when high ethical standards, visibility and impact are all important to authors. Weight Profiling of Low-Molecular Weight Heparins Using Traditionally, the molecular weight distributions of LMWH preparations have been determined using size exclusion chromatography (SEC) with optical detection. Recent advances in liquid chromatography-mass spectrometry methods have enabled exact mass measurements of heparin saccharides roughly up to degree-of-polymerization 20, leaving the high molecular weight half of the LMWH preparation

Award Citation: For his outstanding accomplishments in the theory, development, and use of high-performance affinity chromatography and related methods for separations, chemical analysis, and biomolecular interaction studies. Frontiers | Chemical Modification of Plasticized Lignins Usi The reaction of esterification of plasticized Kraft lignin (KL) with succinic and maleic anhydrides using reactive extrusion (REX) was studied in detail. DMSO, glycol and glycerol were found to be efficient plasticizers for lignin. The chemical structure of these new lignin esters was determined using Solid-state 13C CP-MAS NMR and FT-IR analysis. 31P NMR analysis of phosphitylated lignins
