This work is significant as salinity already affects over 20% of the world's agricultural soils, and salinity poses an increasing threat to food production due to climatechange. The salt-tolerant gene (known as TmHKT1;5-A) works by excluding sodium from the leaves. Richard James and University of Adelaide student Bo Xu.
Kaushal and his team named these cascading effects of introduced salts Freshwater Salinization Syndrome, and it can poison drinking water and cause negative effects on human health, agriculture, infrastructure, wildlife and the stability of ecosystems. In the built environment, salts can degrade roadways and infrastructure.
is creating a streamlined manufacturing process for silicon solar photovoltaic cells that requires only 10% of the silicon, half of the operating and equipment cost, and a quarter of the energy of incumbent technology, enabling sustainable solar manufacturing that will combat climatechange by meeting global demand for solar.
Researchers from George Washington University and Vanderbilt University have demonstrated the conversion of atmospheric CO 2 into carbon nanofibers (CNFs) and carbon nanotubes (CNTs) for use as high-performance anodes in both lithium-ion and sodium-ion batteries. times above that of sodium-ion batteries with graphite electrodes.
The companys plan is to electrochemically strip carbon dioxide out of the ocean, store or use the CO 2 , and then return the water to the sea, where it will naturally absorb more CO 2 from the air. Thats a huge amount of water. The softened water passes through the electrodialysis unit, which applies a voltage.
First, an electric potential will be applied to water to simultaneously produce acidity and alkalinity. The technologies use electricity to extract valuable metal ions from the surrounding mineral matrix at sub-boiling temperatures. Feedstocks will include Li/Ni/Ca/Mg-rich igneous and sedimentary minerals. Idaho National Laboratory.
Some types of lithium mining require a lot of water and energy and have led to local pollution, such as in South America’s alpine lakes. But a new way to firm up the world’s electricity grids is fast developing: sodium-ion batteries. Sodium-ion batteries are now almost ready to fill the long-term storage gap.

Most nuclear plants around the world today are large light-water reactors, with capacities well over a gigawatt—quite a bit more than typical coal plants. Large reactors need consistent and prolific water sources to cool themselves, something not every old coal plant can provide. Either option will be an uphill battle.
There is only so much salt you can dissolve in a glass of water. Importantly, the nanofluids are engineered to remain suspended indefinitely, unlike other suspensions—for instance, sand in water. If you don’t want to wait for it to dry, he adds, you can add more water to reduce the acidity, “then you just shop-vac it up.”
