Green-Mediated Synthesis of NiCoO Nanostructures Using Radish White Peel Extract for the Sensitive and Selective Enzyme-Free Detection of Uric Acid.

The ability to measure uric acid (UA) non-enzymatically in human blood has been demonstrated through the use of a simple and efficient electrochemical method. A phytochemical extract from radish white peel extract improved the electrocatalytic performance of nickel-cobalt bimetallic oxide (NiCoO) during a hydrothermal process through abundant surface holes of oxides, an alteration of morphology, an excellent crystal quality, and increased Co(III) and Ni(II) chemical states. The surface structure, morphology, crystalline quality, and chemical composition were determined using a variety of analytical techniques, including powder X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM), and X-ray photoelectron spectroscopy (XPS).

Advanced Urea Precursors Driven NiCoO Nanostructures Based Non-Enzymatic Urea Sensor for Milk and Urine Real Sample Applications.

The electrochemical performance of NiCoO with urea precursors was evaluated in order to develop a non-enzymatic urea sensor. In this study, NiCoO nanostructures were synthesized hydrothermally at different concentrations of urea and characterized using scanning electron microscopy and X-ray diffraction. Nanostructures of NiCoO exhibit a nanorod-like morphology and a cubic phase crystal structure.

Highly Heterogeneous Morphology of Cobalt Oxide Nanostructures for the Development of Sensitive and Selective Ascorbic Acid Non-Enzymatic Sensor.

The surface tailored metal oxide nanostructures for the development of non-enzymatic sensors are highly demanded, but it is a big task due to the wide range of complexities during the growth process. The presented study focused on the surface modification of the heterogeneous morphology of cobalt oxide (CoO) prepared by the hydrothermal method. Further surface modification was conducted with the use of sodium citrate as a reducing and surface modifying agent for the CoO nanostructures through the high density of oxygenated terminal groups from the citrate ions.

In this study, simple, new and functional silky nanostructures of CoO are prepared by hydrothermal method. These nanostructures are successfully used for the enzyme free sensing of uric acid in 0.1 M phosphate buffer solution of pH 7.

Characterization of Palm Fatty Acid Distillate of Different Oil Processing Industries of Pakistan.

Palm fatty acid distillate (PFAD) is cheap and valuable byproduct of edible oil processing industries. This study was designed to characterize PFAD collected from different local oil industries. AOCS methods were used for the determination of physicochemical parameters such as free fatty acid (FFA), saponification value (SV), iodine value (IV), peroxide value (PV) and moisture content.

Characteristics and Composition of a High Oil Yielding Castor Variety from Pakistan.

Keeping in view the versatile applications of castor oil in cosmetic, pharmaceutical and recently as renewable source, the present work is a step towards the commercialization of castor on large scale in Pakistan. The current study introduces a castor variety with high oil content. Initially seeds were physically examined for some physical parameters.
