Abstract: Getter materials are described. The getter materials have non-evaporable getter alloys in their powder form having high gas sorption efficiency, particularly for hydrogen, carbon oxide and nitrogen, which after having lost their functionality in consequence of the exposure to reactive gases at a first temperature, can then be reactivated through a thermal treatment at a temperature between 400° C. and 600° C. The alloy powders have as compositional elements titanium and silicon and at least one additional metallic element selected among vanadium, iron and aluminum and have an atomic percentage composition of the elements which can vary within the following ranges: 1. Titanium from 60 to 85 atomic percentage; 2. Silicon from 1 to 20 atomic percentage; and 3. The sum of vanadium, iron and aluminum from 10 to 30 atomic percentage.

Abstract: A temperature-sensitive label is described. The temperature-sensitive label has a temperature-sensitive system having a filiform shape memory member that has a first end portion having a terminal part fixedly secured to a first contact member, a second end portion having a terminal part restrained by a second contact member in a non-permanent way, and a central curved portion. The central curved portion is in the martensitic phase while the first and second portions are in the austenitic phase at a same environmental temperature above a critical threshold temperature to be monitored by the label such that in case of exposure to a temperature lower than the preset critical threshold temperature the end portions of the filiform shape member perform a phase transition, from austenitic phase to martensitic phase, which causes its irreversible disengagement from the restraint formed by the second contact member.
