Síntesis de cementantes hidráulicos alternativos mediante la geopolimerización de escorias de fundición de concentrados de pb–zn por Millán Corrales, Guadalupe

“…The obtained products of the reaction were C-S-H, and two insolubles geopolymerics gels N-AS-H and C-A-S-H but with good mechanical properties of up to 60 MPa in RC with 120 days of cured. The curing time and the module silicate were the most important factors on the development of resistance. …”

Contenido de macro y micronutrientes en regosoles en áreas bajo manejo del matorral desértico micrófilo y rosetófilo. por Pérez Pérez, José Eduardo

“…According to the results obtained, it was found that the use of the aerating roller had beneficial effects due to the fact that the treatments showed better conditions in the layers from 0 to 15 cm deep, making the nutrients available to the plants, however, a cyclic use is recommended since over time the nutrients show a lower availability, as it was shown by the comparison of means between the control and the other aeration roller treatments, where it was found that the 9 application of this implement had better results in Ra11, which was one of the most recent applications in the study area.…”

Study on the properties of CuSbS₂ and CuSbSeₓS₂₋ₓ thin films for photovoltaic and photodetector applications por Vinayakumar, Vineetha

“…In addition to the PV device application, we also explored the capability of the CuSbS2 in optoelectronic applications where it was tested as a photodetector for a wide range of wavelengths. For the first time ever, we found that CuSbS2 has great potential as a photodetector as well owing to its high sensitivity towards detection of different wavelength light. …”

Respuesta morfofisiológica y molecular de Atriplex canescens (Pursh) Nutt. a estrés salino y transferencia de halotolerancia hacia un organismo modelo por Garza Aguirre, Raúl Alejandro

“…One specific A. canescens miRNA (aca-miRn1) suffered a meaningful repression, which for complementarity in the sequence, seems to regulate the transcription factor HIG1/MYB51, which at same time controls the genetic expression of two enzyme isoforms from the PGDH family, enzymes that play a very important role in salt stress metabolites synthesis, such as betaine and glutathione. …”
