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 ...
Vibrational spectroscopy studies of biomolecular systems: from amino acids to microorganisms
(2014)
Vibrational spectroscopy: infrared and Raman, was applied to the study of two amino acids and ten bacterial strains with the purpose of developing rapid methods of identification and discrimination. Use of spectroscopic ...
Synthesis and characterization of copper nanoparticles: Architectural morphologies and applications in surface enhanced raman spectroscopy
(2009)
The preparation of copper colloidal suspensions was conducted by three different methods. These methods used wet chemical synthesis, in which a metal salt solution was mixed with a solution containing the reducing agent. ...
Nucleation and growth of silver sulfide nanoparticles
(2010)
The synthesis of metal and semiconductor nanoparticles has received widespread attention by the scientific community due to the large number of technological applications they find in nanoscaled systems. The mechanism of ...
Atomic pair distribution study of the growth of Pt nanoparticles in zeolites
(2016)
The Pair Distribution Function (PDF) is a total scattering method used to study the local structure of a material and yields a function in real space with peaks that represent the interatomic distances. In this work, we ...
Synthesis and surface modification of metallic nanoparticles: Sensitivity, influence of shape, concentration and excitation wavelength on chemical detection by Sers
(2010-05)
Surface-Enhanced Raman Spectroscopy (SERS) is a powerful spectroscopic technique that can be used for detecting analytes at very low concentrations. In SERS, the intensity of vibrational signatures can be enhanced by factors ...
Effect of engineering iron oxide nanoparticles on effluent water quality from biological wastewater treatment
(2013)
The production, use, and disposal of products containing nanoparticles may lead to their appearance in air, water, and soil, and subsequently in the human body. Because there is no existing regulation, large amounts of ...
Composition- and size-controlled synthesis of Mn-Zn ferrite nanocrystals for potential magnetocaloric applications
(2008)
There are presently many applications using nanofluids in thermal engineering. Some examples include the use of nanoparticles in conventional coolants to enhance heat transfer rate by increasing its thermal conductivity. ...
Observation of enhanced Raman scattering as a result of coupling between localized plasmons and surface polariton waves associated with metal-semiconductor nanocomposites
(2011-05)
We report the observation of enhanced Raman scattering as a result of the coupling between the localized surface plasmon (LSP) of metal nanoparticles (NP) and the surface plasmon polariton (SPP) associated with a thin metal ...
Chitosan-based nanoparticles for controlled release of Bromacil
(2018-12)
Herbicides are the most widely used method for weed control. However, the agricultural industry worldwide is facing several challenges including the environmental pollution problems (soils and water) caused by the unsuitable ...
