The ultrastable kinetic behavior of an Au-based nanoglass

Thermomechanical processing of metallic glasses: extending the range of the glassy state

“…years; thus they are not practically accessible by liquid cooling 130 . Metallic glasses deposited by magnetron sputtering at low rates are ultrastable in deposits up to 30 m thick [132][133][134] . In contrast, for pure-metal systems, at T sub << T g the reduced surface mobility leads to unstable deposits that can be regarded as highly rejuvenated; the degree of rejuvenation sustainable at a given temperature is limited by crystallization 11 .…”

“…2c) gives rejuvenated bulk metallic glasses, and permits to obtain nanoglass-like structures in bulk samples, enabling, for example, calorimetric measurements 139 . Although nanoglasses are principally of interest for their high degree of rejuvenation, similar materials made by sputterdeposition 140 have also been associated with ultrastable states 134 .…”

Synthesis of Iron Nanometallic Glasses and Their Application in Cancer Therapy by a Localized Fenton Reaction

“…Thek ey bottleneck is the need for very particular synthesis conditions,s uch as the very high cooling rate (usually higher than 10 6 Ks À1 )t hat is required to freeze the molten metal while suppressing the nucleation of crystalline phases. [4] Cancer therapy by designing agents that are responsive to the tumor microenvironment is another emerging field. The acidic nature (pH 6.5-6.9) of solid tumors has been exploited by the development of many drug release systems (DRSs) where drug release is triggered by low pH values.…”

The evaluation of NiAl- and TiAl-based intermetallic coatings produced on the AISI 1010 steel by an electric current-activated sintering method

“…2(a,b) the interface between coating layer and steel matrix do not include porosity. There are good match between thermal expansion coefficients of NiAl (14.6$10 À6 /K [12]), TiAl (14.4$10 À6 /K [13]) and AISI 1010 steel (14.3$10 À6 /C [14]). Therefore, both TiAl and NiAl coatings were well adhere to the steel samples and there is no any crack at interface.…”
