Disclosed herein are aluminum oxide aerogels and methods of making and use thereof. The methods of making the aluminum oxide aerogel include contacting a solid comprising aluminum with a Ga-based liquid alloy to dissolve at least a portion of the aluminum from the solid, thereby forming an aluminum-alloy mixture; and contacting the aluminum-alloy mixture with a fluid comprising water, thereby forming the aluminum oxide aerogel. In some examples, the methods can further comprise capturing and converting carbon dioxide to a syngas comprising carbon monoxide and hydrogen.

Disclosed herein are aluminum alloy products and methods of making the aluminum alloy products. Specifically, disclosed herein is an aluminum alloy provided in a temper achieved by rapidly quenching the aluminum alloy product after hot rolling. The aluminum alloys provided in the tempers described herein allow an end user to further process the aluminum alloys using less time and requiring less energy.

Disclosed are a susceptor for an aerosol generation apparatus, and the aerosol generation apparatus. The susceptor includes: a metal body, which may be penetrated by a varying magnetic field to generate heat; and a protective layer, formed on the metal body, the protective layer containing a quasicrystal alloy material to reduce adhesion or deposition of organic matter from a smokable material on the surface of the susceptor. When in use, water vapor, aerosol condensation oil, and the like from the smokable material cannot spread on the surface of the quasicrystal alloy material, and can be maintained in a substantially spherical shape and can be easily separated from the susceptor. Meanwhile, solid-phase organic matter such as tobacco slag and carbon deposition falling on the susceptor is difficult to be stubbornly bound to the protective layer, without forming stubborn adhesion or deposition.

Disclosed are aluminum alloy products and methods of making and processing such products. Thus, disclosed are aluminum alloy products exhibiting controllable surface properties, including excellent bond durability, low contact resistance, and corrosion resistance. Aluminum alloy products described herein include a migrant element, a subsurface portion having a concentration of the migrant element, and a bulk portion having a concentration of the migrant element. The aluminum alloy product comprises an enrichment ratio of 4.0 or less, wherein the enrichment ratio is a ratio of the migrant element concentration in the subsurface portion to the concentration in the bulk portion. Additionally, the aluminum alloy products surface and/or subsurface can contain phosphorus (e.g., elemental phosphorus or oxidized phosphorus). The phosphorus containing surface provides reduced electronic stress on an electrode tip of a resistance spot welding apparatus, and an extended service lifetime (e.g., weld cycles to failure) of the electrode tip.
