From the notice

Even small amounts of hydrogen can damage sensitive equipment over time. As hydrogen accumulates inside sealed environments, it can corrode metals, weaken structural materials, degrade electronic components, and, in some applications, create explosion hazards. Preventing that buildup is essential for maintaining the reliability and safety of many high-value systems. Hydrogen getters are materials built into sealed devices and systems to remove hydrogen before it can accumulate. Like a moisture absorber, they remove an unwanted gas. Instead of trapping water, however, they chemically react with hydrogen and lock it away permanently. Depending on the application, a getter may take the form of a pellet, coating, thin film, powder, or printable material. Many commercially available getters rely on zirconium-based materials that offer limited hydrogen storage capacity, require activation before use, or operate effectively only within a narrow temperature range. Some also depend on costly vacuum-deposition manufacturing processes that limit design flexibility. Los Alamos researchers have developed a new class of hydrogen getters designed to overcome these limitations. The materials capture hydrogen and its isotopes, including deuterium and tritium, across a broad range of operating conditions without requiring activation while offering significantly higher storage capacity and greater flexibility for manufacturing and product integration.
