Fully validated simultaneous determination of bisoprolol fumarate and hydrochlorothiazide in their dosage forms using different voltammetric, chromatographic, and spectrophotometric analytical methods
(2013)
Voltammetric, chromatographic, and spectrophotometric methods were developed for the simultaneous determination of bisoprolol fumarate (BIS) and hydrochlorothiazide (HCZ). Differential pulse and square wave voltammetry ...
A validated stability-indicating RP-LC method for the simultaneous determination of amlodipine and perindopril in tablet dosage form and their stress degradation behavior under ICH-recommended stress conditions
(2013)
A stability-indicating RP-LC assay method was developed for the simultaneous determination of the cardiovascular drugs amlodipine and perindopril in the presence of degradation products generated from forced decomposition ...
Determination of pKa values of some butyrophenones, their sensitive LC-UV analysis in pharmaceutical dosage forms and stress degradation behavior under ICH-recommended stress conditions
(2013)
In this study, pKa values of some ionizable butyrophenones, namely, benperidol, droperidol, and haloperidol were determined using by the dependence of the retention factor on pH of the mobile phase. The effect of the mobile ...
Platinized carbon nanoelectrodes as potentiometric and amperometric SECM probes
(2013)
Micrometer-sized platinized carbon electrodes have previously been used for the detection of reactive oxygen and nitrogen species (ROS and RNS) in biological systems. Here, we report the preparation and characterization ...
Fabrication, characterization, and chemical etching of Ag nanoelectrodes
(2013)
The previously developed methodologies for fabricating flat, polished nanoelectrodes were extended to produce silver electrodes with the radii from 50 nm to micrometers. The prepared electrodes were characterized by ...
The effect of TiO2 contained within a titanium silicalite (TS-1) catalyst and on the selective oxidation of ammonia
(Berkeley Electronic Press, 2013)
The selective oxidation of ammonia to hydroxylamine using titaniumsilicalite-1 as a catalyst with an increasing content range of 1-2.5 wt% TiO2 was systematically investigated in a batch reactor. The hydroxylamine yielded ...
Comparisons of dry grinding kinetics of lignite, bituminous coal, and petroleum coke
(Taylor and Francis, 2013)
The objective of this study was to analyze dry grinding kinetics of three different solid fuels in terms of selection and breakage distribution functions values using a batch laboratory ball mill. For this purpose, first, ...
The use of co-polymer flocculants for the elimination of the environmental effects of wastewater of a coal washer and design of a thickener for supplies of fresh water
(Taylor and Francis, 2013)
A washing plant belonging to Özberil Mining Co. (Denizli/Turkey) has a 50 t/h of capacity and coal was washed with heavy media separation to increase its quality. Wastewaters of coal tailing streams of the washing plant ...
Prediction of the bond grindability index from the sink-float test data of coals
(Taylor and Francis, 2013)
In this study, a relation for calculating the Bond grindability by the sink-float test data of coals was studied. Primarily, sink-float tests for three coal samples were made. Secondly, the cumulative weight and ash content ...
Interrelationships between the bond grindability with physicomechanical and chemical properties of coals
(Taylor and Francis, 2013)
In this research, different techniques for the estimation of Bond grindability (Gbg) values of coals are studied. Data from ten sub-bituminous coals from Turkey are used by featuring physicomechanical (ISI, Is, and FD) and ...
