New RNA-based active agents reliably protect plants against the Cucumber mosaic virus (CMV), the most common virus in agriculture and horticulture. They were developed by researchers at the Martin Luther University Halle-Wittenberg (MLU). The active ingredients have a broad spectrum effect; a series of RNA molecules support the plant’s immune system in combating the virus. In laboratory experiments, 80 to 100 per cent of the treated plants survived an infection with a high viral load, as the team reports in…

Innovative process converts CO2 into solid, durable, carbon-trapping materials Using seawater, electricity and carbon dioxide (CO2), Northwestern University scientists have developed a new carbon-negative building material. As Earth’s climate continues to warm, researchers around the globe are exploring ways to capture CO2 from the air and store it deep underground. While this approach has multiple climate benefits, it does not maximize the value of the enormous amounts of atmospheric CO2. Now, Northwestern’s new strategy addresses this challenge by locking away CO2 permanently and turning…

Each year billions of tons of carbon dioxide and other greenhouse gases are released into the atmosphere by the burning of fossil fuels, certain industrial processes, construction and other human activities, creating an urgent need to find better solutions to reduce the levels of atmospheric carbon dioxide. A team of scientists led by Haotian Wang, associate professor in chemical and biomolecular engineering at the George R. Brown School of Engineering and Computing at Rice University, and Xiaonan Shan, associate professor of electrical and computer…

Mesopore introduction enables world-class hydrogen peroxide production characteristics even in low oxygen air supply environments Hydrogen peroxide is one of the world’s top 100 industrial chemicals with a wide range of applications in the chemical, medical, and semiconductor industries. Currently, hydrogen peroxide is mainly produced through the anthraquinone process, but this process has several problems, including high energy consumption, the use of expensive palladium catalysts, and environmental pollution due to by-products. In recent years, an environmentally friendly method of producing…
