Synthesis of Controlled-Size Silica Nanoparticles from Sodium Metasilicate and the Effect of the Addition of PEG in the Size Distribution
(2018-03-28)Silica nanoparticles are widely studied in emerging areas of nanomedicine because they are biocompatible, and their surface can be modified to provide functionalization. The size is intrinsically related to the performance ... -
Synthesis of nanostructured Nickel compounds on conductive metallicsubstrates
(2019-09-16)Nickel hydroxide, oxide, and sulfide films were synthesized on conductive Ni metallic substrates by solidvapor reactions, calcination and hydrothermal methods. The synthesized films were characterized by XRD, XPS, FE-SEM, ... -
Target Field of View Prediction Using Artificial Pheromones for People Reidentification
(2019-12-10)People reidentification is a fundamental task in automated video surveillance based on computer vision. Reidentification happens when a person seen in a field of view is the same that has been observed in other fields of ... -
Target Nanoparticles against Pancreatic Cancer: Fewer Side Effects in Therapy
(2021-11-05)Pancreatic cancer is the most common lethal tumor in America. This lethality is related to limited treatment options. Conventional treatments involve the non-specific use of chemotherapeutical agents such as 5-FU, capecitabine, ... -
