Synergistic response of ionic liquid ([bmim][BF4]) entrapped in BHDC reverse micelles for gold nanoparticles synthesis. Size and morphology control

Blach D., Martinez F., Universidad Industrial de Santander, CO

Nanoparticles (NPs) have been extensively investigated for many application due to their unique properties, particularly gold nanoparticles (AuNPs) stand out because their properties triggered by small changes in their size and morphology. Nowadays, the great [...]

Autonomous Nanosensor System for Monitoring and Quantifying Arsenic in Water

Salinas S., Mosquera N., Yate L., Coy E., Yamhure G., González E., Pontificia Universidad Javeriana, CO

In present work, we have developed a system for detection and quantification of arsenic in water, based on surface plasmon resonance. The sensor uses a gold self-assembled monolayers on Au(111) substrate. Studies that we have [...]

Bacterial Cellulose Nanocomposites Developed by in-situ Fermentation

Osorio M., Restrepo D., Castro C., Montoya U., Zuluaga R., Gañán P., Universidad Pontificia Bolivariana, CO

Some bacteria such as Gluconacetobacter synthesize cellulose nanofibrills (BC) through the polymerization of glucose and subsequent extrusion outside the cell. In static conditions, the bacteria produce a three-dimensional network, a type of pellicule, which can [...]

Transport of Nanomaterials in Complex Media

Ubaque L.A., Vargas W.L., Universidad de los Andes, CO

An appreciable number of researchers have analyzed both the genotoxicity and cytotoxicity of nanoparticles in biological systems, noting extensive damage to most body organs, such effects are attributed to: i) the ease of transportation to [...]

Comparative Analysis for Pseudoboehmite Obtainded by Sol Gel Using Green Chemistry Expert System Sofware

Serna Saiz J., Camargo G., Moreno J.C., Suarez A.F., Universidad Libre, CO

Monohidróxide aluminum, known as pseudoboehmite (AlOOH) was obtained by the sol-gel method by the reaction between aluminum and isopropyl alcohol to produce aluminum isopropoxide using mercuric iodide and Iodine sublimed as catalyst. This work looks [...]

Optimizing the removal of Heavy Metals of an artificial wastewater by electrocoagulation using response surface methodology

Suárez A., Agudelo N., Universidad Libre, CO

The Response Surface Methodology (RSM) was employed to investigate the effects of pH and current density on the removal of cadmium, copper and zinc in a artificial wastewater with a large COD by electrocoagulation technique. [...]
