Albumin Aggregates: Hydrodynamic Shape and Physico-Chemical Properties

Commercially available BSA and HSA preparations are heterogeneous and contain variable proportions of aggregates. Albumin monomer and oligomers have high degree of hydration, high effective negative charge, and high translational diffusion coefficient, which are consistent with the physiological role of albumin. Albumin aggregation involves weak intermolecular interactions and not covalent bonding. All albumin forms show immunological cross-reactivity. The estimated molecular shape of albumin in alkaline solution as prolate ellipsoid reconciles the two opposing models of albumin tertiary structure.

JJC, 2007, 2(2), 169-182

Separation and Spectrophotometric Determination of Platinum (IV) in Natural Waters, Simulated Samples and Prepared Solid Complexes using  1- Phenyl-4-Ethylthiosemicarbazide

A very simple, highly sensitive and selective spectrophotometric procedure was developed for the determination of platinum(IV).

Emission Rates of Gaseous Pollutants from Motor Vehicles

Average emission rates from motor vehicles in Jordan were calculated using a novel approach and found to be 33.9, 198.4, 1.0, and 0.1 gram per kilometer traveled for carbon monoxide, carbon dioxide, hydrocarbons, and nitrogen oxides, respectively with an estimated uncertainty of 10%. Emission rates are found to be dependent on many factors including year of manufacture, engine capacity, and fuel type.
