TL;DR: In this paper, a dye-sensitized solar cells (DSSCs) based on the combination of red (Red spinach) and yellow (Turmeric) natural dyes used as sensitizers for semiconductor TiO2 as electron conductor was investigated.
Journal Article
Simulation and Performance Study of Nanowire CdS/CdTe Solar Cell
TL;DR: In this article, the authors have done modeling and simulation of thin-film CdS/CdTe solar cells and then used nanowire cdS nanowires for using as window layer.
Journal ArticleDOI
Hantavirus: The Next Pandemic We Are Waiting For?
TL;DR: Wang et al. as discussed by the authors focused on the biology, pathogenesis, immunology, epidemiology and future perspective of the Hantaviruses, and provided a data-sharing platform where all the researchers should share and make available all the necessary information such as genomics, proteomics, host-factors, and other epigenetics information, which will encourage the research collaboration in the preparation against the hantavirus.
