It’s important to recycle metal not only for the environmental and economic impact, but also to prevent metal being present in ground water supply,” said Mikel Shecht, executive vice president, Geomet Recycling. “We take the mandatory steps and have processes in place to ensure that the waste our facilities produce is properly disposed to lower the impact on community landfills and the environment at large. Like many other industries, the technology used in waste facilities is evolving quickly.”Geomet Recycling, for example, re...

source:phys.orgA team of researchers at Shanghai Jiao Tong University, working with a pair of colleagues from Harvard University, has developed a new way to synthesize single quantum nanomagnets that are based on metal-free, multi-porphyrin systems. In their paper published in the journal Nature Chemistry, the group describes their method and possible uses for it.Molecular magnets are materials that are capable of exhibiting ferromagnetism. They are different from other magnets because their building blocks are composed of organic molecules or a combination of coordination compounds. Chemists ...

Research on equivalent thermal network modeling for rare-earth giant magnetostrictive transducer source:natureAbstractOf crucial importance for giant magnetostrictive transducers (GMTs) design is to quickly and accurately analysis the temperature distribution. With the advantages of low calculation cost and high accuracy, thermal network modelling has been developed for thermal analysis of GMT. However, the existing thermal models have their limits to describe these complicated thermal behaviors in the GMTs: most of researches focused on steady-state which is incapable of capturing temper...

source:sciencedailyA group of researchers has, for the first time, identified rare earth elements produced by neutron star mergers.Details of this milestone were published in The Astrophysical Journal on October 26, 2022.When two neutron stars spiral inwards and merge, the resulting explosion produces a large amount of heavy elements that make up our Universe. The first confirmed example of this process was an event in 2017 named GW 170817. Yet, even five years later, identifying the specific elements created in neutron star mergers has eluded scientists, except for strontium identified in the...
