Simultaneous nitrification and autotrophic denitrification in fluidized bed reactors using pyrite and elemental sulfur as electron donors
(Elsevier, 2023)In this study, simultaneous nitrification and autotrophic denitrification (SNAD) with either elemental sulfur or pyrite were investigated in fluidized bed reactors in mesophilic conditions. The reactor performance was ... -
Soil fungal abundance and plant functional traits drive fertile island formation in global drylands
(Wiley, 2018)"Dryland vegetation is characterized by discrete plant patches that accumulate and capture soil resources under their canopies. These fertile islands are major drivers of dryland ecosystem structure and functioning, yet ... -
Standardized protocol for determination of biohydrogen potential
(Elsevier, 2020)"Biohydrogen production potential (BHP) depends on several factors like inoculum source, substrate, pH, among many others. Batch assays are the most common strategy to evaluate such parameters, where the comparison is a ... -
Strobilus and seed production of Dioon edule (Zamiaceae) in a population with low seedling density in San Luis Potosí, Mexico
(2013)"We describe strobilus and seed development in a Dioon edule (chamal, palma, dameu') population characterized by low seedling and high adult tree density, in order to improve conservation decisions for this endangered cycad ... -
Structural elucidation and evaluation of multidrug-resistance modulatory capability of amarissinins A–C, diterpenes derived from Salvia amarissima
(2016)"Three new diterpenes (amarissinins A-C, 1–3) containing several oxygenated functionalities were isolated from the leaves and flowers of Salvia amarissima. The structures of these compounds were established through the ... -
Studies of adsorption of heavy metals onto spent coffee ground: equilibrium, regeneration, and dynamic performance in a fixed-bed column
(2016)"Equilibrium and dynamic adsorption of heavy metals onto spent coffee ground (SCG) were studied. The equilibrium adsorption of Cd2+, Cu2+, and Pb2+ in a batch system was modeled by an ion-exchange model (IEM) based on an ... -
Study of the effect of the dispersion of functionalized nanoparticles TiO2 with photocatalytic activity in LDPE
(2016)"A photodegradable Low Density Polyethylene-Titanium dioxide (LDPE-TiO2) nanocomposite film was prepared, and its evaluation considers the partial modification of the surface of the particle using Hexadecyltrimethoxysilane ... -
Synthesis and photophysical properties of ferrocene-oligo(benzoateethynylene)- fulleropyrrolidines dyads and triads. Implications in photovoltaic cells
(2018)"A series of fulleropyrrolidines-conjugated bridge-ferrocene or triazene oligomers were selectively synthesized by the Sonogashira reaction by applying the step-by-step approach. The bridge is constituted by 1, 2 and 3 ... -
Synthesis of Bamboo-like Multiwall Carbon Nanotube–Poly(Acrylic Acid-co-Itaconic Acid)/NaOH Composite Hydrogel and its Potential Application for Electrochemical Detection of Cadmium(II)
(MDPI, 2020)"A poly(acrylic acid-co-itaconic acid) (PAA-co-IA)/NaOH hydrogel containing bamboo-type multiwall carbon nanotubes (B-MWCNTs) doped with nitrogen (PAA-co-IA/NaOH/B-MWCNTs) was synthesized and characterized by SEM, absorption ... -
Synthesis of keratine, silver, and flavonols nanocomposites to inhibit oxidative stress in pancreatic beta-cell (INS-1) and reduce intracellular reactive oxygen species production
(Elsevier, 2021)"Flavonols (FLA) from Vaccinium macrocarpon (V. macrocarpon) were identified using high-performance liquid chromatography coupled with mass spectrometry detection. Nanoparticles were prepared using highly crosslinked keratin ... -
Synthesis of reduced graphene oxide (rGO) films onto carbon steel by cathodic electrophoretic deposition: anticorrosive coating
(Elsevier, 2017-10)"The use of graphene based materials as anticorrosive coatings for the protection of metals is still a controversial subject worthy of debate. The electrophoretic deposition (EPD) is one of the most used techniques to ... -
Synthesis, structural characterization and Cu(II) adsorption behavior of manganite (γ-MnOOH) nanorods
(Royal Society of Chemistry, 2020)"New alternatives for the removal of transition metal ions that present an environmental risk are required. The chemical adsorption of these ions on surfaces with chemisorbent properties represents a promising area of ... -
Tailoring partially reduced graphene oxide as redox mediator for enhanced biotransformation of iopromide under methanogenic and sulfate-reducing conditions
(Elsevier B.V., 2017-01)"This work reports the first successful application of graphene oxide (GO) and partially reduced GO (rGO) as redox mediator (RM) to increase the biotransformation of the recalcitrant iodinated contrast medium, iopromide ... -
Technical note: application of geophysical tools for tree root studies in forest ecosystems in complex soils
(2017-11)"While semiarid forests frequently colonize rocky substrates, knowledge is scarce on how roots garner resources in these extreme habitats. The Sierra San Miguelito Volcanic Complex in central Mexico exhibits shallow soils ... -
