exhibited a self-healing property and provided effective long-term protection for Mg-Li alloy. YU et al [136] designed a nano-sized molybdate pillared hydrotalcite (HT-MoO42-)/in-situ created ZnO... of elongation. But the long period stacking ordered (LPSO) structure introduced into Mg-Li alloys can improve the strength and elongation at the same time [37]. In addition, severe plastic......
activity after long-term SRM reaction. Similar treatments were conducted by SEYEDI et al [94]. A series of CuO/ZnO/Al2O3/ ZrO2 catalyst was prepared by using hybrid coprecipitation-plasma methods... that perform a high catalytic activity and long-term stability are highly desired; 4) The design of the reformer should enhance the heat transfer from PEMFC to micro reformer, maximizing the energy......
at least 700 °C for a long time, material will be softened due to the reduced mechanical properties at high temperatures. Besides, materials are exposed to liquid metal and thus liquid metal corrosion......
with long calcinations time, resulting in low specific surface area. In order to enlarge their surface area, perovskite-type oxides with various morphologies, including nanosheets [2, 3], nanofibers [4, 5... were stoichiometrically mixed, and then directly sintered for a long time at high temperature in air to obtain the pure phase perovskite oxide powder, known as high temperature solid method [16-18......
environments, it is difficult to meet standard curing conditions. Therefore, initial damage inside engineering structures occurs, adversely affecting the mechanical properties and durability... establishment According to LONG’s [35] compound damage model idea, the damage constitutive model of RCM under uniaxial compression was established considering rubber particles and dry-curing......

power sources to supply energy for long-term low-power undersea applications. In Mg-Al-Zn series alloys, aluminum plays important role in inhibiting the self-discharge, whereas zinc decreases... condition, it usually has a long shelf life. The structure of the basic seawater activated battery is shown in Fig. 1 [9]. In the course of discharge, seawater acting as the electrolyte is poured......

It is also called the long-term strength [31], whose value is the corresponding stress value [32] of the volumetric strain inflection... to the exponential relationship with a constant term. This indicates that water has slight effects on longitudinal wave velocity at each loading stage. When the final macro fracture surface......
