Estructura de edades, densidad y regeneración de Pinus hartwegii en un gradiente de elevación. by Cortés Cabrera, Héctor Enrique

“…Due to the altitudinal migration of temperatures according to forecasts of climate change, it is expected that species will migrate along with the temperatures to higher elevations. We compared the regeneration of Pinus hartwegii in the elevation gradient of the species (3,050, 3,225 y 3400m in elevation), and compared the number of adult individuals with fire scars and regeneration. …”

Synthesis and characterization of tin sulfide nanomaterials and thin films by pulsed laser ablation in liquid. by Johny, Jacob

“…Moreover, colloidal graphene oxide was mixed with SnS nanocolloids at different volume concentrations (0.1%, 0.5% and 1%) to obtain SnS: GO or SnS: rGO thin films where the nanocomposite films showed enhanced opto-electronic and electrochemical properties compared to the pristine SnS thin films. A solar cell configuration of glass/ CdS/ Sb2S3/ SnS:rGO was also fabricated using the SnS: rGO layer as the absorber and photoconversion efficiency of 2.3% was achieved. …”
