The local and observed photochemical reaction rates revisited
(Royal Society of Chemistry, 2009-06)
In a broad sense, photochemical reactions proceed through pathways involving several reaction steps. The initiation step is the absorption of energy both by the reactant or sensitizer molecules and in some cases, by the ...
KINETICS OF QUALITY CHANGES DURING FRYING
(S/EDITORIAL, 2008)
This paper deals with kinetics of quality changes during food frying. The quality parameters of interests include color, texture, viscoelastic properties, volume/density, and nutraceuticals (Omega 3 fatty acids). The kinetic ...
Kinetics of the Esterification of Maleic Anhydride with Castor Oil
(Plapiqui, 2011-03)
Kinetics reaction between castor oil and maleic anhydride without condensation and catalyst was studied. On the other hand, the products concentration, kinetics and thermodynamics parameters were determined using mathematical ...
Kinetic parameters of red pepper waste as biomass to solid biofuel
(2016-03-01)
This work aimed to study the kinetic of thermal degradation of red pepper waste as solid biofuel to bioenergy production. The thermal degradation experiments were conducted at three heating rates, 5 °C/min, 7.5 °C/min and ...
Pharmaceuticals photochemical reactions
(Nova Science Publishers, 2012)
Photolytic degradation can be a major limiting factor in the stability of pharmaceuticals. A drug may be chemically affected by the radiation of a particular wavelength only if it absorbs radiation at that wavelength and ...
Vertical ground reaction forces are associated with pain and self-reported functional status in recreational athletes with patellofemoral pain
(2015-12-01)
Individuals with patellofemoral pain (PFP) use different motor strategies during unipodal support in stair climbing activities, which may be assessed by vertical ground reaction force parameters. Thus, the aims of this ...
An Empirical Model To Obtain The Kinetic Parameters Of Lignocellulosic Biomass Pyrolysis In An Independent Parallel Reactions Scheme
(ELSEVIER SCIENCE BVAMSTERDAM, 2015)
Exploring chemical kinetics at home in times of pandemic: Following the bleaching of food dye allura red using a smartphone
(American Chemical Society, 2021-05-12)
In this communication, a remote experimental activity in chemical kinetics is described, taking into account the quantification based on the optical sensor of a smartphone. The objective pursued herein is to equip students ...
A Multivariate curve resolution approach to the study of the degradation kinetics of valsartan under photolytic and acid conditions
(Wiley, 2013-06)
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 ...
