Influence of protons on reduction degree and defect formation in electrochemically reduced graphene oxide
(Elsevier, 2019)"The electrochemical reduction of GO was investigated in aqueous, at both acid and basic pH, and organic media, to identify the possible role of protons (H+) in the reduction mechanism of this material. The obtained rGO ... -
Tecia solanivora infestation increases tuber starch accumulation in Pastusa Suprema potatoes
(Wiley, 2018)"In response to infestation with larvae of the Guatemalan tuber moth (Tecia solanivora), some Solanum tuberosum (potato) varieties exhibit an overcompensation response, whereby the total dry mass of uninfested tubers is ... -
A new computer program TecDIA for multidimensional tectonic discrimination of intermediate and acid magmas and its application to the Bohemian Massif, Czech Republic
(Czech Geological Society, 2015)"A new computer program TecDIA written in Java, for the application of 35 previously-defined multidimensional diagrams for the tectonomagmatic discrimination of intermediate and acid magmas is briefly described. A detailed ... -
Seasonal Precipitation Legacy Effects Determine the Carbon Balance of a Semiarid Grassland
(Wiley, 2019)"Semiarid grasslands are water‐limited ecosystems where precipitation (PPT) controls the onset and duration of the growing season; however, this variable does not fully explain interannual variability of productivity at ... -
Enhancement of NOx photo-oxidation by Fe-doped TiO2 nanoparticles
(NRF, 2019)"Microwave hydrothermal-assisted sol-gel method was employed to synthesize the Fe doped TiO2 photocatalyst. Themorphological analysis suggests anatase phase nanoparticles of ~20 nm with an SBET area of 283.99 m2/g. The ... -
Impact of Carbon Nanomaterials on the Antioxidant System of Tomato Seedlings
(MDPI, 2019)"Tomato is one of the most economically important vegetables worldwide and is constantly threatened by various biotic and abiotic stress factors reducing the quality and quantity in the production of this crop. As an ... -
The Sulfate-Rich and Extreme Saline Sediment of the Ephemeral Tirez Lagoon: A Biotope for Acetoclastic Sulfate-Reducing Bacteria and Hydrogenotrophic Methanogenic Archaea
(Hindawi, 2011)"Our goal was to examine the composition of methanogenic archaea (MA) and sulfate-reducing (SRP) and sulfur-oxidizing (SOP) prokaryotes in the extreme athalassohaline and particularly sulfate-rich sediment of Tirez Lagoon ... -
Switched systems based on unstable dissipative systems
(International Federation of Automatic Control, 2015)"In this work we present an unified theory of how to yield multi-scroll chaotic attractors based on step function, saturation, hysteresis and deterministic Brownian motion. This class of systems is constructed with a ... -
An Output-Feedback PID-type Global Regulator for Robot Manipulators with Bounded Inputs
(International Federation of Automatic Control, 2015)"An output-feedback PID-type controller for the global stabilization of manipulators with bounded inputs is proposed. It guarantees the global regulation goal preventing input saturation while avoiding the exact knowledge ... -
Constraining a density-dependent flow model with the transient electromagnetic method in a coastal aquifer in Mexico to assess seawater intrusion
(Springer, 2019)"Saltwater intrusion is one of the most pressing environmental concerns in coastal areas with increased water demands. Water extraction decreases the level of fresh groundwater, reducing the water pressure and allowing ... -
Magnetic characteristics of fracture zones and constraints on the subsurface structure of the Colima Volcanic Complex, western Mexico
