Application of Newton’s Zero Order Caustic for Analysis and Measurement: Part II Fluorescence

Antonio A. Garcia, Luis Nuñez, Carissa Henricksen & Vladimiro Mujica · International Research Journal of Pure and Applied Chemistry · 2013

An oblate spheroid-shaped liquid solution acts as a lens through the phenomenon of Newton’s zero order caustic resulting in the focusing of a low power source into high intensity light within the sample to detect and measure fluorescence. Microwatt LED sources can be used to meas...

Comparative Studies of Isotherm and Kinetics on the Adsorption of Cr (VI) and Ni (II) from Aqueous Solutions by Powder of Mosambi Fruit Peelings

R. Hema Krishna · International Research Journal of Pure and Applied Chemistry · 2013

This study focuses on the use of powder of Mosambi fruit peelings (PMFP) as an inexpensive and efficient adsorbent to remove Cr(VI) and Ni (II) from aqueous solutions. The influence of physico-chemical key parameters such as the initial metal ion concentration, pH, agitation time...

Application of Newton’s Zero Order Caustic for Analysis and Measurement: Part-I Absorbance

Antonio A. Garcia, Luis Nuñez, Charles John, Habtom Hadish, Victor Orioke & Vladimiro Mujica · International Research Journal of Pure and Applied Chemistry · 2013

When light is incident upon a liquid solution droplet containing a light absorbing solute and it is formed into a spheroid shape, absorbance can be measured and related to concentration of the light absorbing species in a manner analogous to standard spectrophotometry. However, t...

Azamacrocycle Complexes: Synthesis and Xanthine Oxidase and Antioxidant Activity

A. Bushra Begum, V. Lakshmi Ranganatha, T. Prashanth, M. S. Asha, Farhan Zameer, Raghavendra Hegdekatte & Shaukath Ara Khanum · International Research Journal of Pure and Applied Chemistry · 2013

Aims: Gout is caused by high uric acid in the blood that leads to excess uric acid crystallizing in the joints causing swelling and pain. Uric acid is produced from the breakdown of the purine which is released when cells die or introduced from the food we eat. The enzyme that he...

Kinetics and Mechanism of Oxidation of Gabapentin by N-bromosuccinimide in Aqueous Alkaline Medium. Comparing to the Kinetics of Oxidation by N-bromosuccinimide in Aqueous Acid Medium

Alaa Eldin Mokhtar Abdel-Hady · International Research Journal of Pure and Applied Chemistry · 2013

The kinetics of oxidation of gabapentin (GBP) by N-bromosuccinimide (NBS) in an alkaline medium has been investigated. The oxidation reaction showed unique kinetics that greatly differed on going from acid to base medium.  In an acid medium (pH=2.52), the reaction rate showed fir...
