STUDY OF KINETIC FORMATION AND THE ELECTROCHEMICAL BEHAVIOR OF POLYPYRROLE FILMS
(Sociedad Chilena de Química, 2009)
A numerical study of the Lieb-Thirring kinetic energy lower bound
(Taylor and Francis, 2016)
In this work, the Lieb-Thirring kinetic energy bound is numerically examined for a variety of systems: the hydrogen-like atoms, neutral atoms, isoelectronic series of atomic ions, the Hooke's atom and some small molecules. ...
Stability study and degradation kinetics of ceftazidime in pharmaceutical preparations
(Scientific & Academic Publishing, 2012)
Stability study of ceftazidime was realized in order to investigate kinetics of degradation of this drug both in powder for injection and reconstituted sample. Ceftazidime was submitted to conditions of accelerated thermal ...
Benzoxazine resin and their nanostructured composites cure kinetic by DSC
(Cambridge University Press, 2013-11-28)
Benzoxazine resins are a new class of thermosetting phenolic resins that have emerged in recent decades, overcoming the traditional properties of epoxy and phenolic resins applied in the aerospace industry. The incorporation ...
Kinetic studies of urban solid residues and leachate from sanitary landfill
Urban solid residues are constituted of food remaining, grass leaves, fruit peelings, paper, cardboard, rubber, plastic, etc. The organic fraction formed represents about 50% during the decomposition yields biogas and ...
Crystallization kinetic of fluoro-zirconate glasses by non-isothermal analysis
(Kluwer Academic Publ, 2003-01-01)
Fluoride glasses have been extensively studied due to their high transparency in the infrared wavelength. The crystallization kinetics of these systems has been studied using DTA and DSC techniques. Most of the experimental ...
Drying kinetics of tomato by using electric resistance and heat pump dryers
(Marcel Dekker Inc, 2004-01-01)
Drying kinetics of tomato was studied by using heat pump dryer (HPD) and electric resistance dryers with parallel and crossed airflow. The performance of both systems was evaluated and compared and the influence of ...
Cure Kinetic of Castor Oil-Based Polyurethane
This research presents the kinetic studies on the cure reactions of a new material, castor oil-based polyurethane resin. Thermal analysis by isothermal differential scanning calorimetry was used, as a variety of factors ...
A Multivariate curve resolution approach to the study of the degradation kinetics of valsartan under photolytic and acid conditions
The analysis of UV-spectrophotometric data with second-order chemometrics techniques, including multivariate curve resolution with alternating least-squares (MCR-ALS) and hybrid hard- and soft MCR (HS-MCR), was examined ...
