Trend analysis and forecasting air pollution in Rwanda [PDF]
arXiv, 2022 Air pollution is a major public health problem worldwide although the lack of data is a global issue for most low and middle income countries. Ambient air pollution in the form of fine particulate matter (PM2.5) exceeds the World Health Organization guidelines in Rwanda with a daily average of around 42.6 microgram per meter cube.

Advanced Functional Materials, EarlyView.In this study, a novel facet‐junction strategy is proposed to enhance the strong metal‐support interaction (SMSI) between the loaded Ru atoms and the Co3O4 support. The synthesized structure with the incorporation of Ru doping and the (100)/(111) crystal plane junction has a particular influence on the catalyst's hydrogen evolution reaction (HER ...

Advanced Functional Materials, EarlyView.Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

Toward Large-Scale Autonomous Monitoring and Sensing of Underwater Pollutants [PDF]
arXiv, 2020 Marine pollution is a growing worldwide concern, affecting health of marine ecosystems, human health, climate change, and weather patterns. To reduce underwater pollution, it is critical to have access to accurate information about the extent of marine pollutants as otherwise appropriate countermeasures and cleaning measures cannot be chosen. Currently
