The petition Four young men in Port Harcourt, Rivers State, remain missing two months after being unlawfully arrested by personnel of the Special Anti-Robbery Squad. The four were arrested at Boss Lounge, a popular nightclub along Woji Road in GRA, Port Harcourt, on Sunday, January 5, 2020 around 8:00pm and their whereabouts have remained unknown…
Terror group, ISIS, has instructed members to stay safe and avoid killing anybody at the moment. In a full-page infographic on the back cover of its most recent Al-Naba Newsletter, the terror group gave a list of tips instructing fighters how to stop the spread of Coronavirus. Since the pandemic broke out in China, the…
Scientists are working around the clock to understand the biology of the covid-19 virus and how it infects human cells, which will help us design treatments to stop it Read More https://www.newscientist.com/article/mg24532743-500-were-beginning-to-understand-the-biology-of-the-covid-19-virus/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home Views: 0
In recent years, lithium-based batteries have become widely used to power a wide range of electronic devices, including tablets, smart phones and portable computers. These batteries have different compartments, called cells, each of which contains a positive electrode and a negative electrode separated by a chemical known as an electrolyte.

There may be many overlooked organic and inorganic materials that could be used to harness sunlight underwater and efficiently power autonomous submersible vehicles, report researchers at New York University. Their research, publishing March 18 in the journal Joule, develops guidelines for optimal band gap values at a range of watery depths, demonstrating that various wide-band…
Solar cells are photovoltaic devices that convert light to electricity. During the photoelectric conversion process, a photovoltaic device internally undergoes multiple charge-carrier dynamics processes. These internal charge-carrier processes intrinsically dominate the performance of a photovoltaic device itself.

Photovoltaic solar cells are a promising alternative to fossil fuels, but they need to be a lot more efficient before they can go into widespread use. Scientists have pushed current supercomputing power to the limit looking for that improved efficiency, but the arrival of exascale computing within the next few years will allow them to…
Colloidal quantum dot (CQD) solar cells have attracted considerable attention due to the advantages of being flexible and lightweight. Additionally, they are much easier to manufacture compared to commercial silicon solar cells in use today. Now, researchers report a novel technology capable of maximizing the performance of the existing CQD solar cells. Read More Views:…
Titanium dioxide (titania) thin films are commonly used in various types of solar cells. The fabrication methods that are currently used to create such titania films require high temperatures, as well as expensive, high-end technologies. Researchers at Delft University of Technology (TU Delft) have now developed a fully organic method to engineer porous titania thin…
