The novel properties can serve as a promising platform for exploring exotic quantum phases and electromagnetism.
Published Engineers 'symphonize' cleaner ammonia production
(via sciencedaily.com) Original source Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the high temperatures and energy needed to manufacture it. But by improving on a well-known electrochemical reaction and orchestrating a 'symphony' of lithium, nitrogen and hydrogen atoms, engineers have developed a new ammonia production process that meets several green targets.

Published Heat, cold extremes hold untapped potential for solar and wind energy
(via sciencedaily.com) Original source Conditions that usually accompany the kind of intense hot and cold weather that strains power grids may also provide greater opportunities to capture solar and wind energy. A study found that widespread, extreme temperature events are often accompanied by greater solar radiation and higher wind speeds that could be captured by solar panels and wind turbines. The research, which looked at extensive heat and cold waves across the six interconnected energy grid regions of the U.S. from 1980-2021, also found that every region experienced power outages during these events in the past decade. The findings suggest that using more renewable energy at these times could help offset increased power demand as more people and businesses turn on heaters or air conditioners.
Published A new type of cooling for quantum simulators
(via sciencedaily.com) Original source Quantum simulators are quantum systems that can be controlled exceptionally well. They can be used to indirectly learn something about other quantum systems, which cannot be experimented on so easily. Therefore, quantum simulators play an important role in unraveling the big questions of quantum physics. However, they are limited by temperature: They only work well, when they are extremely cold. Scientists have now developed a method to cool quantum simulators even more than before: by splitting a Bose-Einstein-condensate in half, in a very special way.
