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. ... -
Enhancement of perchlorate removal from groundwater by cationic granular activated carbon: Effect of preparation protocol and surface properties
(Elsevier, 2018)"In order to obtain a high adsorption capacity for perchlorate, the epoxide-forming quaternary ammonium (EQA) compounds were chemically bonded onto granular activated carbon (GAC) surface by cationic reaction. The optimum ... -
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 ... -
Climate change in forest ecosystems: A field experiment addressing the effects of raising temperature and reduced rainfall on early life cycle stages of oaks
(Elsevier, 2018)"Higher temperatures and reduced rainfalls that are expected with the advance of climate change can impair the emergence and establishment of tree seedlings in forest ecosystems. These climatic changes can also decrease ... -
TRUE GRASP: Actors visualize and explore hidden limitations of an apparent win-win land management strategy in a MAB reserve
(Elsevier, 2018)"Win-win solutions might be short-lived. Government permission for smallholder farmers to extract and sell resin from a pine savanna biosphere-reserve in Mexico has settled a long dispute among different stakeholders in ... -
Rheological behavior from light to heavy oils: construction of master curves
(American Chemical Society, 2016)"In this work, the rheological behavior of heavy and light stabilized (dead) oils is presented. The viscosity measurements were carried out in two different apparatuses to ensure the repetitiveness and accuracy: a Stabinger ... -
Agave bagasse biorefinery: processing and perspectives
(Springer, 2018)"Agave bagasse (AB) is the main solid waste generated by the tequila industry in Mexico, which is an environmental concern due to its considerable volume of production (377,000 Ton in 2016). AB is a lignocellulosic biomass ... -
Habitat suitability models to make conservation decisions based on areas of high species richness and endemism
(Springer, 2018)"Biodiversity positively relates with the provisioning of ecosystem services and preserving areas with elevated diversity of highly-functional species could help to ensure human well-being. Most studies addressed to make ... -
Mathematical modeling of a composting process in a small-scale tubular bioreactor
(Elsevier, 2017)"A mathematical model is presented to describe a composting process occurring in a tubular bioreactor. The mathematical model is based on heat and mass transfer phenomena under the continuum approximation. The bioreactor ... -
Temporal and spatial variation of waterbirds at Sayula Lagoon, Jalisco, Mexico: a five-year winter season study
(Museu de Ciencies Naturals, 2018)"Wetlands in central Mexico are important habitats for assemblages of migratory and resident birds. To study variation in richness and abundance of waterbirds, we conducted monthly observations in 30 permanent plots ... -
Hydrogen metabolic patterns driven by Clostridium-Streptococcus community shifts in a continuous stirred tank reactor
(Springer, 2018)"The hydrogen (H2) production efficiency in dark fermentation systems is strongly dependent on the occurrence of metabolic pathways derived from the selection of microbial species that either consume molecular H2 or ... -
Evaluation of a membrane bioreactor system as post-treatment in waste water treatment for better removal of micropollutants
(Elsevier, 2016)"Organic micropollutants (OMPs) such as pharmaceuticals are persistent pollutants that are only partially degraded in waste water treatment plants (WWTPs). In this study, a membrane bioreactor (MBR) system was used as a ... -
Acorn weight as determinant of germination in red and white oaks: evidences from a common-garden greenhouse experiment
(Springer, 2018)"Key message In Mexican oaks, germination increases with acorn fresh weight across oak species. Within species, these relationships are stronger in red oaks than in white oaks. In both oak groups, fresh weight of acorns ... -
Aberraciones cromáticas en Aves de México: Una revisión y registros recientes en el Estado de San Luis Potosí
(Neotropical Ornitholigical Society, 2018)"La presencia de aberraciones cromáticas en las aves ha llamado la atención de los investigadores desde hace mucho tiempo. En México se ha notado un reciente incremento de artículos publicados referente a este tema. Por ... -
Methanogenic and Sulfate-Reducing Activities in a Hypersaline Microbial Mat and Associated Microbial Diversity
