Room-temperature aging phenomena
has been documented for different types of ferrous alloys, including cast irons and steels.
Abstract: We explored aging phenomena
in actual solder joints by nano-mechanical testing of single SAC 305 solder joints extracted from PBGA assemblies.
In China, people do not correctly know AD for a long time, believing that the decline in cognitive functions and memory losses of the elderly are normal aging phenomena
. Therefore, only some brain cell resurrection drugs (such as Oxiracetam and Piracetam) or antioxidants (e.g., Ginkgo Biloba Preparation) are generally applied at home for the treatment of AD for quite some time, with extremely limited curative effects.
Perera (3) has claimed that physical aging phenomena
have an impact on the formulation, application, and the service life behavior of organic coatings in many domains.
Considering that nanoscale-dispersed particles may act as nucleating agents during foaming process to produce finer cell structure and they can also improve the gas barrier properties, the use of nanoparticles may lead to a sensible enhancement of foam morphology, and thus thermal insulating properties of PUR foams, and to a reduction of the thermal aging phenomena
. It is generally known  that the addition of particles (nucleation agents) reduces the nucleation free energy, thus favoring the formation of nucleation centers.
