Standoff laser-Induced thermal emission of explosives
(2013)
A laser mediated methodology for remote thermal excitation of analytes followed by standoff infrared (IR) detection is proposed. The goal of this study was to determine the feasibility of using laser induced thermal emission ...
Electrochemistry of Hemoglobin I from Lucina pectinata immobilized on a modified gold electrode with cysteine or 3-mercaptopropionic acid: Electrochemical activity for hydrogen sulfide
(2012)
The extraordinary affinity of recombinant hemoglobin I from Lucina pectinata (rHbI) for hydrogen sulfide (H2S) allow to postulate it as substrate for the preparation of the hydrogen sulfide sensors. The modification of a ...
Thermal inkjet technology for the deposition of nanoparticles and Metal-organic framework (Mof): Preparation of sers-active substrates and Mof films for In-situ enhanced raman and infrared detection of harmful contaminants
(2012-12)
The applications of thermal ink-jet printing technology as deposition technique of functional materials such as metal nanoparticles and microporous nickel-oxalate metal organic framework were studied. Highly sensitive ...
Design and development of remote Raman spectroscopy system for detection of hazardous compounds
(2012-11)
Remote Raman detection has become a powerful analytical technique for detection of hazardous compounds in situ and without sample preparation at distances away from the observation site. This study describes the design, ...
Aluminum tolerance, growth, and organic acid exudation in rambutan (Nephelium Lappaceum)
(2012)
A randomized complete block design experiment with six aluminum (Al) concentrations was carried out to evaluate the effect of aluminum on nutrient content, dry matter (DM) production and Al-induced organic acid exudation ...

The present research was conducted to investigate the in vitro cytotoxic activity of
dichloromethane extracts obtained from the leaves of sourpsop (Annona muricata L.) on human
colon cancer cell line HT-29, as an alternative ...
Electrochemical redox process analysis of Cu+2 and Fe+3 ions in natural waters using cyclic voltammetry technique
(2012-12)
The concentration and distribution of trace metals in natural water is important in order to have a better understanding of their biogeochemical behavior and natural cycles. This biological behavior and natural cycles are ...
Development of calibration models for the in-line prediction of active pharmaceutical ingredient concentration in the range 0-100% W/W by near infrared and Raman spectroscopy
(2013)
The development of quantitative calibration models by near infrared (NIR) and Raman spectroscopy with the capability of predicting concentration in a wider range than the currently used approach will be described. Current ...
Synthesis and characterization of bulk and colloidal magnetic polymer nanocomposites
(2013)
The development of bulk and colloidal latex polymer nanocomposites of poly (methyl methacrylate) (PMMA) with embedded magnetic nanoparticles particles was investigated. The first approach consisted of the preparation of ...
