While compressed gases are used in a host of applications, there are considerable dangers associated with using chemical elements stored under pressure. Explosion of cylinders is one of the most common hazards, a malfunction that's usually caused by mechanical damage or over-pressurisation. The hig...
shipping over land or sea. When shipped, it must either be in liquid form or transformed into ammonia. Both are expensive processes, and liquefying hydrogen is technically challenging as well: it needs to be cooled down to –252°C, one of the lowest boiling points of all the elements. ...
The first real evidence for these elements dates back to the eighteenth century, when the very concept of a chemical element was in its infancy, but it took a hundred years for this evidence to be properly appreciated. The noble gases seemed at first to violate all the known rules of ...
Simpler design.Higher power ranges allow for simpler designs and fewer passive elements. By 2027, more than 50 percent of battery electric vehicles (BEVs) could rely on SiC powertrains, compared with about 30 percent in 2024. This shift, combined with a growing preference for BEVs among EV ...
