Corrosion resistance of carbon steel covered with resin coating containing nickel sulfate has been evaluated under chloride and sulfuric acid mist environment. The structure corrosion products formed on surface was investigated by XRD XAFS analyses using synchrotron radiation. Nickel promoted the formation goethite akaganeite. It considered that this akaganeite not tetragonal β-FeOOH but monocl...

in this study, blueberry essential oil as a core material was microencapsulated with inulin and β-cyclodextrin at a ratio of 1:5 (core: wall). oil in water nano-emulsions were prepared by ultrasonic liquid processors and then transformed to encapsulate powder in spray dryer. dried powder was stored at 4 ˚c in refrigerator for determining moisture, encapsulation efficiency and morphology prop...

one of the methods to enhance bio-accessibility of drugs like acridone and its oxime is toform inclusion complexes with β-cyclodextrin. the formation of such complexes has beenconfirmed by changes in spectral characteristics and melting point data. the aqueous phasesolubility studies reveal 1:1 stoichiometry between the compound and, β-cyclodextrin. the studyof thermodynamic parameters like δg,...

Soft attachment of streptavidin to β-cyclodextrin-modified pegylated SAMs was efficiently performed in a reversible and repetitive way via orthogonal bifunctional linkers involving streptavidin-biotin recognition and redox-driven multivalent host-guest (β-cyclodextrin-ferrocene) interactions.

A green chiral lab-on-a-chip cyclodextrin-based microchip electrophoretic method was developed for enantioseparation of baclofen (BCN) and phenylalanine (Phe) enantiomers the first time. All BCN Phe were offline labeled with 4-fluoro-7-nitrobenzofurazan (NBD-F) or fluorescein-5-isothiocyanate (FITC) fluorogenic reagents prior to microfluidic injection in a dynamically coated polymethylmethacryl...

Finasteride (FIN) is a Class II candidate of the Biopharmaceutics Classification System (BCS). The lipophilic cavity of cyclodextrins (CyDs) enables it to construct a non-covalent inclusion complex with different insoluble drugs. Only β-cyclodextrin (β-CyD) and hydroxypropyl-β-CyD (HP-β-CyD) have been previously examined with FIN. This study aimed to investigate the consistence of FIN with diff...

Microalgae are recognized as a third generation feedstock for biofuel production due to their rapid growth rates and lignin-free characteristics. In this study, a lipid extracted microalgal biomass residues was used as the raw material to produce isoprene, α-pinene and β-pinene with an engineered E. coli strain. We adopted an optimal sulfuric acid hydrolysis method (1:7 ratio of solid to acid s...

Pioglitazone, a class II Biopharmaceutical Classification System drug having poor water solubility and slow dissolution rate may have a negative impact on its subtherapeutic plasma drug levels leading to therapeutic failure. In order to improve its water solubility and thus dissolution, cyclodextrin complexation technique was followed. The phase solubility studies were carried using three diffe...
