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. ...

The discharge of wastewater from the dyeing industry is an environmental concern across the world. These effluents are considered highly toxic since they contain high concentrations of synthetic dyes, which are a great ...

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 ...

The recombinant polyhistidine-tagged hemoglobin I ((His)6-rHbI) from bivalve Lucina pectinata is an ideal biocomponent for a hydrogen sulfide (H2S) biosensor due to its high affinity for H2S. Nowadays it is clear that H2S ...

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 ...

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 ...

As a consequence of growing water demand and pollution, water borne disease outbreaks are on the rise and current disinfection methods have shown to be ineffective in inactivating all pathogens during water treatment. Zinc ...

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. ...

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 ...
