In this project mesoporous silica will be synthesized to encapsulate antigens, insulin, and polyaniline (PAni). Nitrilic rubber will be mixed with silica and PAni by mechanical milling. The external computer control of a pressure cell will be performed, in order analyze in-situ Small Angle X-ray Scattering (SAXS) data of the compounds under pressure inside the silica matrix. The morpholo…
This project aims the growth and characterization of nanoparticles formed by oxides of iron, titanium, aluminum, cerium, paladium and lanthanum, prepared by sol-gel, as well as the study of their catalytic and paramagnetic properties. The proposal involves a detailed study about the synthesis of coloidal suspensions made of oxy-hydroxides of transition metals and rare earths. Also, metall…

The goal of this work is the investigation of how the porous structure influences the encapsulation yield and release of proteins from two different ordered mesoporous silia (SMOs).In this study we will use the model protein BSA and crotoxin to determine the respective encapsulation yield and release dynamics. The main characterization techniques will be in-situ small angle X-ray scatteri…
This research project aims to use 3 different structure swelling agents in the synthesis of mesoporous silica SBA-15 in order to obtain a mean pore diameter of at least 16 nm, determined by sorption measurements. Different concentrations of the swelling agents will be tested. Changes in the structure will be analyzed by Small Angle X-ray Scattering (SAXS). These silicas will be used to en…
In this postdoctoral project it is proposed to synthesize ordered mesoporous silicas (OMSs) and analyze the encapsulation and release of antigens in an oral formulation of poly-vaccines. The capability of encapsulation in these new silicas will be tested for diphtheria and tetanus anatoxins. The release process will be analyzed in samples without and with a polymeric coverage resistant to…

We propose the synthesis and characterization of ordered mesoporous silica (OMS) with new morphology as functional adjuvants for tetanus and diphtheria oral vaccines. For this study, our focus will rely on two mesoporous materials: SBA-15 and FDU-12. In addition to the regular synthesis, we will modify the reaction and hydrothermal treatment temperature, agitation and include a swelling a…
Persistent luminescence (PeL) materials are attracting strong scientific interest nowadays due to their ability of storage of luminous energy for considerable periods of time. This stored energy can be used in a variety of applications, from emergency lighting to medical diagnoses and imaging. However, the improvement of the PeL materials is based on the try and error basis, mostly changi…
