Testing the Test: A Comparative Study of Marine Microbial Corrosion under Laboratory and Field Conditions
(AMER CHEMICAL SOC, 2021-06-25)Microbially influenced corrosion (MIC) is an aggressive type of corrosion that occurs in aquatic environments and is sparked by the development of a complex biological matrix over a metal surface. In marine environments, ... -
Toward Controlled Morphology of FeCu Nanoparticles: Cu Concentration and Size Effects
(AMER CHEMICAL SOC, 2018)Bimetallic nanoparticles (NPs) can be tailored by varying the concentration of their constituent elements, resulting in novel structures and/or configurations, leading to interesting electronic, mechanical, and chemical ... -
Tri-functional oligomeric polyesters prepared from new dicarboxylic acids containing several amino acids residues by Higashi methodology: synthesis, characterization, and study of solubility and thermal behavior
(Chile. Universidad Mayor, 2021)The synthesis of polyfunctional aliphatic oligomeric polyesters (poly(ether-imido-esters;PEIEs) containing several amino acid residues is described, and their thermal properties and solubility behavior were studied. The ... -
Tuning the structure and magnetic behavior of Ni-Ir-based nanoparticles in ionic liquids
(ROYAL SOC CHEMISTRY, 2018)We report on a simple preparation of extremely small diameter (ca. 2 nm) Ni-Ir-based NPs using Ni(COD)(2) and [Ir(COD)OCH3](2) in 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMImNTf(2)). The prepared NPs ... -
Using classical Cepheids to study the far side of the Milky Way disk: I. Spectroscopic classification and the metallicity gradient
(Chile. Universidad Mayor, 2020)Context. Much of what we know about the Milky Way disk is based on studies of the solar vicinity. The structure, kinematics, and chemical composition of the far side of the Galactic disk, beyond the bulge, are still to be ... -
Using Femtosecond Laser Irradiation To Grow the Belly of Gold Nanorods
(AMER CHEMICAL SOC, 2018)Irradiation of gold nanorods can lead to the formation of several new nanostructures. One of the most interesting among them are phi-shaped rods, a stable intermediate shape in the rod-to-sphere conversion process, but not ... -
Utilization of industrial by-product fungal biomass from Aspergillus niger and Fusarium culmorum to obtain biosorbents for removal of pesticide and metal ions from aqueous solutions
(Chile. Universidad Mayor, 2020)In this work, Aspergillus niger and Fusarium culmorum cell wall by-products were chosen as microbial sources for chitin and chitosan production. Both polysaccharides were characterized by FTIR and C-13-CPMAS NMR, but GPC ... -
UV-VIS spectroelectrochemical in situ study during the electrosynthesis of copolymers
(SOC CHILENA QUIMICA, 2019)In this work, the synthesis of poly(aniline-co-o-methoxyaniline) is performed using purely electrochemical techniques, coupled to UV-vis spectroscopy in situ, in 3D. The electrocopolymerization is carried out on ITO ...
