ZnO/p-Si heterostructure for UV sensing and long-range IoT environmental monitoring

The development of low-cost photoconductive ultraviolet sensors with long-range wireless communication remains an attractive approach for environmental monitoring applications. In this work, a ZnO/p-Si photoconductive heterostructure was fabricated by spray pyrolysis and experime...

Green synthesis for production of chromium(III) oxide nanoparticles in fine powder

In this paper, a green synthesis method for chromium(III) oxide nanoparticles (Cr 2 O 3 NPs) is presented. The proposed route utilizes weed biomass as a reducing agent to produce a solid solution that readily precipitates as a fine powder of Cr₂O₃ nanoparticles. The synthesized C...

Techno-Spatial and Economic Assessment of Rooftop Versus Land-Based Photovoltaic Deployment in a Biodiversity-Sensitive Region of the Mexican Caribbean

Solar photovoltaic (PV) expansion in fast-growing tropical regions requires engineering-based frameworks that compare deployment pathways in terms of electricity generation, spatial footprint, and economic performance. This study develops a techno-spatial and economic assessment...
