A lysimeter study under field conditions of nitrogen and phosphorus leaching in a turf grass crop amended with peat and hydrogel
Elsevier (2019)olf courses represent an agricultural activity wherein grass is intensively cultivated using large quantities of fer- tilizers. In the present study, nitrogen and phosphorus leaching was analyzed over two years in an ... -
Bio-Nanocomposite Hydrogel Based on Zinc Alginate/Graphene Oxide: Morphology, Structural Conformation, Thermal Behavior/Degradation, and Dielectric Properties
MDPI (2020)Bio-nanocomposite hydrogels based on sodium alginate (SA) as polymer matrix and graphene oxide (GO) nanosheets with zinc as crosslinking agent were synthesized with the aim of incorporating the intrinsic properties of ... -
Effects of different amendments (organic matter and hydrogel) on the actual evapotranspiration and crop coefficient of turf grass under field conditions
John Wiley and Sons (2020-11-16)The irrigation schedule in arid areas has to be efficient in order to reduce losses due to evaporation and deep infiltration. Irrigation optimization poses the need to establish with precision the value of actual ... -
Study of the effect of polymorphism on the self-assembly and catalytic performance of an L-proline based molecular hydrogelator
Royal Society of Chemistry (2015)An exhaustive study of the polymorphism found for aggregates and hydrogels of an L-proline based hydrogelator under different preparation conditions is undertaken. The effect of heating temperature, aging time, ultrasound ... -
Vibrational Circular Dichroism Shows Reversible Helical Handedness Switching in Peptidomimetic l-Valine Fibrils
American Chemical Society (2012)We elucidate the supramolecular organization in the form of microsize fibrils of gels formed by a l-Valine peptidomimetic compound. Analysis was based on circular dichroism spectroscopies, vibrational (VCD) and electronic ...
