Mercury Redox Chemistry in the Negro River Basin, Amazon: The Role of Organic Matter and Solar Light
(Springer, 2010-03-01)
Pristine water bodies in the Negro River basin, Brazilian Amazon, show relatively high concentrations of mercury. These waters are characterized by acidic pH, low concentrations of suspended solids, and high amounts of ...
Light intensity and sowing depth on the emergence and development of weeds
(Soc Brasileira Ciencia Plantas Daninhas-sbcpd, 2021-01-01)
Background: Weeds are one of the ecological factors that affect the agricultural economy permanently. Thus, understanding the weed emergence and development is essential in decision making for management strategies. ...
Simulations of photocurrent improvement through combined geometric/diffracting light trapping in organic small molecule solar cells
(Wiley, 2013-04)
Although organic solar cells have recently shown remarkable high power conversion efficiencies approaching 12%, further improvements are needed to become a low cost alternative to current inorganic photovoltaic technologies. ...
Towards High Throughput Texturing of Polymer Foils for Enhanced Light Trapping in Flexible Perovskite Solar Cells using Roll‐to‐roll Hot Embossing
(Wiley VCH Verlag, 2019-12)
A path to further increase the power conversion efficiency of perovskite solar cells is maximizing sunlight absorption by using patterned substrates with enhanced light trapping capabilities. However, to be competitive ...
Estudo de iluminação solar zenital com garrafas PET
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2013-05-03)
The purpose of this study is to evaluate the use of daylighting through top openings reusing materials. 2l PET bottles were adopted as test material. The study was carried out using PET bottles in a scale model, so that ...
