As freshwater scarcity becomes more prevalent, solar evaporation is drawing attention as a promising solution. This process uses sunlight to heat the surface of salty or contaminated water, turning it into vapor that can be collected as clean water when it condenses.
Scientists have developed an air purifier charged by sunlight and indoor LED lights, potentially offering an inexpensive, lower-maintenance alternative to standard filtration systems that protect users from pollutants and airborne diseases. The study, published in the journal Chem, shows that the air filter maintained 99% of its maximum filtration efficiency after a month of use…
Researchers at AIST, in collaboration with researchers at the National Institute of Technology, Kagoshima College, have developed the Anaerobic Baffled Continuous Stirring (ABCS) reactor, a device capable of simultaneously treating solid waste and wastewater from biomanufacturing processes while recovering methane for energy self-sufficiency.
Scientists project that by 2050, nearly half the global urban population will not have enough potable water—a 50% increase since 2016. New and sustainable methods for desalination are needed, and Cornell researchers have one potential solution—in part inspired by the bird of paradise.
University of Warwick researchers have created a new material combining two properties, magnetism and electrical polarization, that scientists have struggled to bring together for decades—and crucially, it works close to room temperature.
Until now, it has been almost impossible to measure the energy density of hydrogen precisely, but a new sensor can register every single molecule. This could lay the foundation for correct accounting in the hydrogen economy.
Lithium-ion batteries (LiBs), which charge and discharge by moving lithium ions between two electrodes known as the cathode and anode, remain the most widely used rechargeable batteries worldwide. Over the past decades, however, energy engineers have been assessing the potential of alternative rechargeable batteries based on different materials and ions.
Steel pipelines used for oil and gas transportation remain the backbone of energy infrastructure. Hence, there is heavy focus on their integrity and resistance to degradation in corrosive conditions. Sour corrosion, a dangerous form of pipeline steel degradation when exposed to H2S, typically found in crude oil and natural gas, causes continuous hydrogen uptake into…
A novel approach for making carbon-carbon composites could replace the slow, labor-intensive manufacturing process that has constrained the material’s availability and driven up its cost.
A new study finds that composite metal foam (CMF) could significantly improve automobile safety during frontal collisions. Using computational models to run detailed simulations, researchers found that incorporating CMF into automobile “front rails” would allow them to absorb more energy during high-velocity impacts.
