The Science Newswise — Solar hydrogen generation is a promising technology for using sunlight to convert water into hydrogen fuel. This technology could be both efficient and economical. One approach uses materials called metal oxides, including one that combines the elements bismuth and vanadium. To make hydrogen, cells made of these materials, called photoelectrodes, are…
Newswise — Methane’s role as a climate driver has become increasingly clear, particularly in sectors like waste management and fossil energy. While high-concentration methane can be burned for energy recovery, low-level emissions from industrial vents or agricultural sources often escape treatment due to high costs or inefficient technologies. Conventional combustion-based methods can also produce secondary…
Newswise — The Korea Institute of Machinery and Materials (President Seog-Hyeon Ryu, hereinafter referred to as KIMM), under the National Research Council of Science & Technology (Chairperson Kim, Yeung-Shik), has developed a technology that stably generates high photocurrent under natural sunlight to efficiently produce hydrogen. By simplifying previously complex multi-step processes, this advancement drastically reduces…
BYLINE: Kyra Gurney Newswise — South Florida residents are willing to pay more in taxes to fund both gray climate adaptation projects, like seawalls, and green ones, such as mangrove forests, but the benefit-cost ratio for green infrastructure projects is more than double that of gray, according to a University of Miami study. The study,…
Newswise — With the advent of the 5G era, the demand for high-speed and large-capacity data transmission in optical fiber communication is becoming increasingly urgent. As a core component of optical communication, the performance of electro-optic modulators highly depends on the electro-optic coefficient, response speed, and stability of the material. However, traditional materials (such as…
Newswise — As global demand for food continues to rise, pesticide usage is intensifying—bringing unintended ecological consequences. Nanopesticides, which allow for controlled release and targeted action, are positioned as a more efficient and less environmentally disruptive solution. However, uncertainties persist, particularly regarding their fate in ecosystems post-application. Traditional risk assessment methods often neglect early-stage emissions…
Newswise — Drylands, covering 42% of the Earth’s land surface and supporting 38% of the global population, are at the forefront of the battle for scarce water resources. The relentless expansion of agriculture has placed immense pressure on these fragile ecosystems, with many tail-end lakes shrinking or vanishing entirely due to excessive irrigation. The urgency…
Newswise — Sustainably produced, biodegradable materials are an important focus of modern materials science. However, when working natural materials such as cellulose, lignin or chitin, researchers face a trade-off. Although these substances are biodegradable in their pure form, they are often not ideal when it comes to performance. Chemical processing steps can be used to…
There are 17 elements that make up the materials called rare earth elements. Each of these can be used to make rare earth metals. While some metals like gold, silver, copper and platinum, are mined in their metallic forms, others, including iron, aluminum, and lead are found in mineral ores and must be chemically processed…
Newswise — A notable number of anticancer drugs consist of heterocycles, owing to their capability of interacting with the biotargets like nucleic acids, enzymes, and receptors. Nature has a massive repository of molecules consisting of heterocyclic rings with strong or potentially significant anticancer activity against a plethora of cancer cell lines and tumor micro-environments. In…
