Analysis of the Evolution of Tannic Acid Stabilized Gold Nanoparticles Using Mie Theory
International Journal of Analytical Chemistry - Tập 2014 - Trang 1-6 - 2014
Assia Rachida Senoudi, Sidi Mohammed Chabane Sari, Ilhem F. Hakem
Spherical gold nanoparticles (GNPs) have been synthesized in aqueous solutions using sodium citrate (SC) and tannic acid (TA) as reducing and stabilizing agents. Upon addition of TA and compared to the GNP TA-free aqueous solutions, a reduction of the GNPs size and consequently a dramatic change of their optical properties have been observed and quantitatively analyzed using Mie theory.

Sensitive Determination of Terazosin in Pharmaceutical Formulations and Biological Samples by Ionic-Liquid Microextraction Prior to Spectrofluorimetry
International Journal of Analytical Chemistry - Tập 2012 - Trang 1-7 - 2012
Mohsen Zeeb, Mahdi Sadeghi
An efficient and environmentally friendly sample preparation method based on the application of hydrophobic 1-Hexylpyridinium hexafluorophosphate [Hpy][PF6] ionic liquid (IL) as a microextraction solvent was proposed to preconcentrate terazosin. The performance of the microextraction method was improved by introducing a common ion of pyridinium IL into the sample solution. Due to the presence of t... hiện toàn bộ
Recent Developments in Sweat Analysis and Its Applications
International Journal of Analytical Chemistry - Tập 2015 - Trang 1-7 - 2015
Saima Jadoon, Sabiha Karim, Muhammad Rouf Akram, Abida Kalsoom Khan, Muhammad Abid Zia, Abdul Rauf Siddiqi, Ghulam Murtaza
Currently, the clinical use of sweat as biofluid is limited. The collection of sweat and its analysis for determining ethanol, drugs, ions, and metals have been encompassed in this review article to assess the merits of sweat compared to other biofluids, for example, blood or urine. Moreover, sweat comprises various biomarkers of different diseases including cystic fibrosis and diabetes. Additiona... hiện toàn bộ
Production of Palmitoleic and Linoleic Acid in Oleaginous and Nonoleaginous Yeast Biomass
International Journal of Analytical Chemistry - Tập 2016 - Trang 1-9 - 2016
Irena Kolouchová, O Schreiberová, Karel Sigler, Jan Masák, Tomáš Řezanka
We investigated the possibility of utilizing both oleaginous yeast species accumulating large amounts of lipids (Yarrowia lipolytica, Rhodotorula glutinis, Trichosporon cutaneum,andCandidasp.) and traditional biotechnological nonoleaginous ones (Kluyveromyces polysporus, Torulaspora delbrueckii,andSaccharomyces cerevisiae) as potential producers of dietetically important major fatty acids.

Green Synthesis and Characterization of Silver Nanoparticles Using Citrullus lanatus Fruit Rind Extract
International Journal of Analytical Chemistry - Tập 2017 - Trang 1-9 - 2017
Michael Ndikau, Naumih M. Noah, Dickson Andala, Eric Masika
The wide-scale application of silver nanoparticles (AgNPs) in areas such as chemical sensing, nanomedicine, and electronics has led to their increased demand. Current methods of AgNPs synthesis involve the use of hazardous reagents and toxic solvents. There is a need for the development of new methods of synthesizing AgNPs that use environmentally safe reagents and solvents. This work reports a gr... hiện toàn bộ
Particle Morphology Analysis of Biomass Material Based on Improved Image Processing Method
International Journal of Analytical Chemistry - Tập 2017 - Trang 1-9 - 2017
Zhaolin Lu, Xiaojuan Hu, Yao Lu
Particle morphology, including size and shape, is an important factor that significantly influences the physical and chemical properties of biomass material. Based on image processing technology, a method was developed to process sample images, measure particle dimensions, and analyse the particle size and shape distributions of knife-milled wheat straw, which had been preclassified into five nomi... hiện toàn bộ
