h-BN/NiS2/NiS nanocatalysts for removing rhodamine B and Cr(VI) in wastewater
The human health is suffering from effluent containing heavy metal ions (such as Cr(VI)) and organic dyes (such as rhodamine B). Among numerous strategies to remove pollutants from water, photocatalysis has attracted extensive attention due to its lo.....»»
Turning wastewater into valuable proteins with genetically modified yeast
The growing world population means that the environment is under great strain. Agriculture takes up large land areas and discharges nutrients to the surrounding environment. At the same time, there is tremendous pressure on the aquatic environment fr.....»»
"Mirror" nuclei help connect nuclear theory and neutron stars
Adding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom's electrons, known as isotope shifts. Scientists can use precision measurements of these.....»»

For many people, the aroma of freshly brewed coffee is the start of a great day. But caffeine can cause headaches and jitters in others. That's why many people reach for a decaffeinated cup instead......»»
Studies explore converting wastewater to fertilizer with fungal treatment
Creating fertilizers from organic waste can help reduce the consumption of fossil fuels and promote sustainable production. One way of doing this is through hydrothermal liquefaction (HTL), which converts biomass into biocrude oil through a high-temp.....»»
Understanding willingness to pay for nationwide wastewater surveillance in Japan
Globally, the COVID-19 pandemic and the increased likelihood of other such outbreaks in the future warrant the strengthening of epidemic surveillance systems. Among these, continuous wastewater surveillance at wastewater treatment plants is considere.....»»
Real-life "stillsuit": Dune-inspired upgrade for spacesuits allow astronauts to recycle urine into water
Astronauts on spacewalks famously have to relieve themselves inside their spacesuits. Not only is this uncomfortable for the wearer and unhygienic, it is also wasteful, as—unlike wastewater on board the International Space Station (ISS)—the water.....»»
