Elucidating the role of graphene oxide on the methanogenic activity of anaerobic consortia
(2020)"Graphene is a nanomaterial of great interest due to its interesting mechanical, optical and electrical properties, ideal for the development of new materials and devices in all fields of technology; however, its large-scale ... -
The contribution of dew and fog in the water balance of a continental semiarid grassland ecosystem
(2020-01)"In arid and semiarid regions, water scarcity plays an important role in determining the plant distribution, density, cover and productivity; it also controls many other biological processes. In these regions, different ... -
Co-digestión de Scenedesmus obtusiusculus con sustratos ricos en carbono para la producción de biogás
(2019-12)"El uso de biomasa microalgal como sustrato para la producción de biogás resulta una alternativa interesante para aprovechar este tipo de biomasa dado su contenido de materia orgánica. Sin embargo, la biomasa microalgal ... -
Cinética de captura de CO2 en fibras de bagazo de agave carbonizadas e impregnadas con el líquido iónico acetato de 1-butil-3-metilimidazol
(2019)"El uso de combustibles fósiles aumenta las concentraciones de CO2 en la atmósfera, situación que causa efectos negativos al ambiente, sin embargo, es importante considerar que existen procesos industriales que requieren ... -
Partículas hidroxiladas de Fe:Ce soportadas en una red polimérica para remover As(V) de agua
(2019-10)"Actividades como la minería, el uso de plaguicidas, la quema de combustibles fósiles entre otros, ha tenido un impacto en la concentración de arsénico en cuerpos de agua destinados al consumo humano, lo que ha provocado ... -
Human impacts and aridity differentially alter soil N availability in drylands worldwide
(Wiley, 2016)"Aims Climate and human impacts are changing the nitrogen (N) inputs and losses in terrestrial ecosystems. However, it is largely unknown how these two major drivers of global change will simultaneously influence the N ... -
Factores que influyen en la ocupación de hábitat en la temporada de reproducción del gorrión de Worthen (Spizella wortheni) en el Altiplano Potosino
(2019-09-17)"El Gorrión de Worthen (Spizella wortheni), es una especie endémica y amenazada del Altiplano Mexicano que se asocia a pastizales naturales y matorrales. Su rango de distribución ha disminuido significativamente en los ... -
Impact of emerging, high-production-volume graphene-based materials on the bioavailability of benzo(a)pyrene to brine shrimp and fish liver cells
(Royal Society of Chemistry, 2018)"With increasing commercialization of high volume, two-dimensional carbon nanomaterials comes a greater likelihood of environmental release. In aquatic environments, black carbon binds contaminants like aromatic hydrocarbons, ... -
Graphene oxide triggers mass transfer limitations on the methanogenic activity of an anaerobic consortium with a particulate substrate
(Elsevier, 2018)"Graphene oxide (GO) is an emerging nanomaterial widely used in many manufacturing applications, which is frequently discharged in many industrial effluents eventually reaching biological wastewater treatment systems (WWTS). ... -
Screening of commercial sorbents for the removal of phosphates from water and modeling by molecular simulation
(Elsevier, 2018)"Eight commercial sorbents of different origin and nature were studied in the present work for the removal of phosphate from water using synthetic solutions and a wastewater from an anodizing company. The materials included ... -
Improved conductivity and anti(bio)fouling of cation exchange membranes by AgNPs-GO nanocomposites
(Elsevier, 2018)"Nafion and Ultrex membranes were modified with nanocomposites (NCs) of silver nanoparticles (AgNPs) immobilized on graphene oxide (GO) as a thin film, using a polydopamine adhesive (pda). The morphological, physicochemical, ... -
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 ... -
Chitosan-macroalgae biocomposites as potential adsorbents of water-soluble hydrocarbons: organic matter and ionic strength effects
(Elsevier, 2018)"Nowadays the recovery of low-molecular soluble aromatic hydrocarbons (HCs) released into natural bodies of water continues to be a challenging task. These contaminants bring sever consequences to the environment and to ... -
Sulfate reduction at acidic conditions: from the sediment to the reactor
(2019-09)"Acid mine drainage is water polluted with heavy metals, sulfate, and acid as the result of some mining activities. Due its physicochemical characteristics, acid mine drainage is toxic, recalcitrant and difficult to treat. ... -
