For a few hundred dollars, a bedroom can be refreshed with the latest flat-pack offerings. Wood particleboard furniture is affordable and generally easy to assemble, but particleboard is often held together with formaldehyde-based resins that make it hard or impossible to recycle. Now, with the help of science, old pressed-wood furnishings could be repurposed, and new modular decor could incorporate more environmentally friendly materials. Four articles published in ACS journals reveal how.
For decades researchers have been exploring how to store data in glass because of its potential to hold information for a long time — eons — without applying power. A special type of glass that changes color in different wavelengths of light, called photochromic glass, holds promise for stable, reusable data storage. Now, researchers have developed a doped photochromic glass that has the potential to store rewritable data indefinitely, according to research published in ACS Energy Letters.
Per- and polyfluoroalkyl substances (PFAS) are known as forever chemicals because of their extreme persistence. These compounds have useful properties including durability and waterproofing, so they’re commonly used in consumer products like food packaging and cosmetics, as well as industrial processes. But PFAS’ potential negative impacts on human health are driving the search for potentially safer substitutes. Now, researchers publishing in ACS’ Environmental Science & Technology propose alternatives for many applications.
As traditional candles burn, they can contribute to indoor air pollution by emitting volatile compounds and smoke, which may pose inhalation risks. Scented wax melts are often marketed as safer alternatives to candles because they’re flame- and smoke-free. But in a study in ACS’ Environmental Science & Technology Letters, researchers describe how aroma compounds released from the melted wax can react with ozone in indoor air to form potentially toxic particles.
Agricultural fertilizers are critical for feeding the world’s population, restoring soil fertility and sustaining crops. Excessive and inefficient use of those resources can present an environmental threat, contaminating waterways and generating greenhouse gases such as nitrous oxide. Now, researchers reporting in ACS Agricultural Science & Technology have addressed those challenges with glass fertilizer beads. The beads control nutrient release, and the researchers say they’re environmentally compatible.
