Aqueous Solvent

Amphiphilic porphyrin derivatives adsorbed onto silica nanoparticles via noncovalent interactions have been prepared and characterized. The organic-inorganic hybrids have been obtained by simply stirring a nanoparticle suspension into an aqueous solvent mixture of porphyrin aggregates. The systems obtained show good stability in aqueous solvents, at different pH, and also in toluene. Analogous protocol has been applied to the macrocycles in monomeric form, obtaining the corresponding nanoparticle-porphyrin adducts. These systems are of interest for the development of sensors and medicinal application.

Two Stages

In this work, the production of biologically synthesized silica nanoparticles was proposed to prepare a nanosuspension as a thermal fluid in parabolic solar panels at the laboratory level. Silica nanoparticles were produced from construction sand in two stages. Biosynthesis broth was produced by Aspergillus niger aerated fermentation in a 1 L bioreactor for 9 days. Each supernatant was contacted with 18% construction sand in a 500 L reactor with mechanical agitation, at a temperature of 25 °C, and a contact time of 30 min. Subsequently, the separation process was carried out. For day 9, a pH value of 1.71 was obtained as well as acid concentrations of 15.78 g/L for citrus and 4.16 g/L for malic. The metal extraction efficiency of Si nanoparticles was 19%. The vibration peaks in the FTIR were characteristic of the presence of silica nanoparticles in wavenumbers 1020 cm−1 and 1150 cm−1. Finally, a prototype solar radiation test bench for parabolic systems was built and provided with a radiation source that falls on a translucent pipe that transports the nanoparticles, which has a pump and a series of thermocouples. The heat capacity of the biotechnologically produced silica nanoparticle suspension was 0.72 ± 0.05 kJ/kgK, using material and energy balances in the flow circuit.
