Hydrogen sulfide gas has the unmistakable aroma of rotten eggs. It often emanates from sewers, stockyards and landfills, but it is particularly problematic for refineries, petrochemical plants and other industries, which make thousands of tons of the noxious gas each year as a byproduct of processes that remove sulfur from petroleum, natural gas, coal and …

Rainbows are produced when water droplets refract sunlight. Sunlight and rainfall are therefore essential ingredients for rainbows. Human activities such as burning fossil fuels are warming the atmosphere, which changes patterns and amounts of rainfall and cloud cover. “Living in Hawai’i, I felt grateful that stunning, ephemeral rainbows were a part of my daily life,” …

The heat waves that swept across Europe this summer made many people realize how important plants are when it comes to cooling down the environment. But how do the various types of vegetation in the Arctic affect the energy exchange between the Earth’s surface and its atmosphere? This is a highly relevant question, since the …

Publishing their findings in Atmospheric Environment: X, the researchers measured auxiliary heater (AH) particulate emissions from the preheating of three gasoline, and three diesel cars for a half an hour period. Preheating was carried out outdoors in sub-zero conditions, i.e., when preheating is recommended by the AH manufacturer. In terms of particulate emissions, using an …
Now, new research from the lab of Kimberly Parker, an assistant professor of energy, environmental and chemical engineering at Washington University in St. Louis’ McKelvey School of Engineering, has shed new light on this story by demonstrating for the first time that these amines themselves volatilize, often more than dicamba itself. Their findings were published …

The team, led by Associate Professor Xue Jun Min, Dr Wang Xiaopeng and Dr Vincent Lee Wee Siang from the Department of Materials Science and Engineering under the NUS College of Design and Engineering (NUS CDE), found that light can trigger a new mechanism in a catalytic material used extensively in water electrolysis, where water …

PFAS, often referred to as “forever chemicals,” are used to make fluoropolymer coatings and products that resist heat, oil, stains, grease and water, and are found in a variety of products from clothing and furniture to food packaging and non-stick cooking surfaces. “PFAS are so pervasive and persistent that they have been found in the …

Yet, the work of the LHC isn’t done. It is currently in its third run and being prepared for a high luminosity upgrade that will lead to more collisions and thus the creation of more Higgs particles. But eventually the accelerator will need to be retired and replaced. The comparisons of power consumptions or luminosity …

Now, a new study published in the journal Nature has calculated that the globalized supply chain saved countries $67 billion in solar panel production costs. The study also found that if strong nationalistic policies that limit the free flow of goods, talent and capital are implemented going forward, solar panel costs will be much higher …
