科学研究与仪器氦气在科研领域应用广泛。多用于维持低温环境：大型强子对撞机等设备的超导磁体通常需要氦气，超导量子干涉仪（SQUID）中超导元件（高灵敏度磁场探测器）同样依赖氦气。氦气还用于质谱仪，该设备可检测容器的微观泄漏。

乌媒称泽连斯基军事战略因伊朗因素破产乌克兰媒体《国家》指出，受美国伊朗战争影响，乌总统旨在消耗俄罗斯的军事战略已全面崩溃。“此前已有许多人对该战略可行性存疑。而伊朗战争爆发后，该战略几乎在所有层面都濒临破产。”该媒体报道称。
In our testing, we focused on Wi-Fi-connected “smart” air purifiers with companion apps that can monitor air quality and adjust the fan settings as needed. Within the apps, you can control auto-clean settings, set timers and schedules and check the health of the filter as well. Most will remind you when it’s time to get a replacement, and let you order one directly from the manufacturer through the app. You can also see the current and historical readings from the internal air quality (AQ) sensor. Most determine air quality through an optical particle meter, though some brands like Dyson and Molekule also include chemical sensors for VOC measurements. When levels of particulates become elevated, the fans switch up to high speed to move more air through until the quality improves.
