Use of polydimethyl siloxane microparticles for the sequestering of model pollutants in water
(2009)
Polymer micro and nanoparticles are an emerging type of material with promising applications for remediation and degradation of environmental contaminants in water, due to their enhanced surface area and chemical reactivity. ...
Estudio químico y actividad citotóxica de extractos de la hoja de guanábana (Annona muricata L.)
(2014)
The present research was conducted to investigate the in vitro cytotoxic activity of
dichloromethane extracts obtained from the leaves of sourpsop (Annona muricata L.) on human
colon cancer cell line HT-29, as an alternative ...
Femtosecond spectroscopy studies of recombinant hemoglobin I of the clam Lucina pectinata (Gmelin, 1791)
(2011)
Lucina pectinata (Gmelin, 1791) is a clam that can be found in sulfide-rich muds in the
coastal mangroves of the southwest coast of Puerto Rico. It contains three different
hemoglobins in the gill tissue, hemoglobin I, ...
Synthesis, characterization, binding interactions with biomolecules and cytotoxic studies of molybdebocene complexes
(2009)
Bis-(cyclopentadienyl) molybdenum dichloride or molybdenocene dihalides, like other metallocenes dihalides, have shown antitumor properties in different human tumors. In contrast to titanocene dichloride, molybdenocene ...
Hemoglobin I from Lucina pectinata: A model for hydrogen sulfide reactivity within hemeproteins
(2009)
The hemoglobin I (HbI) from the clam Lucina pectinata is an intriguing hemeprotein that binds and transports H2S to chemoautotrophic bacteria to maintain a symbiotic relationship and to protect the mollusk from H2S toxicity. ...
Sulfheme formation mechanism and spectra analysis using QM/MM and TDDFT
(2018-05)
Since the 1863 discovery of a new green hemoglobin derivative called “sulfhemoglobin”, the
nature of its characteristic 618 nm absorption band and formation mechanism has been the subject of
several hypotheses. Many ...
Optimization of biodiesel production process using recycled vegetable oil
(2010)
Petro diesel toxic emissions and its limited resources have created an interest for the
development of new energy resources, such as biodiesel. Biodiesel is traditionally produced
by a transesterification reaction between ...
Síntesis y estudios mecanísticos de complejos de molibdenoceno: Interacción de agentes metálicos anti-cáncer con el transporte de proteínas
(2012)
Nuevos complejos organometálicos fueron sintetizados, partiendo del dicloruro de molibdenoceno (Cp2MoCl2) y cuatro ligandos: L-Acido ascórbico(L-AA), 6-o-palmitoil-L- acido ascórbico (PAA), Etil maltol y D-penicilamina, ...
Removal and speciation of oxyanions from aqueous solutions using Ca-Fe(III) alginate beads and dried sludge as adsorbents
(2013)
Oxyanions are highly soluble species, which are pH and redox dependant, and represent a toxic and hazardous species to humans and for the environment. Various remediation techniques have been applied such as: precipitati ...
Synthesis, characterization and mild detemplation of novel cobalt rich SBE type nanoporous materials
(2012)
The optimization of the synthesis, extended characterization and evaluation of the adsorption properties of cobalt-rich SBE type aluminophosphates (CoAPO-SBE) were investigated. According to X-ray diffraction (XRD), scanning ...
