[交流] 翻译一句话

Recently, it has shown that silicon leaching can be also used to fabricate octadecasil nanocrystals (10–25 nm) with a high degree of intercrystalline porosity and a preserved structure.

As noted above, desilication mostly creates intracrystalline
porosity in channel-type zeolites such as ZSM-5, ZSM-12,
mordenite, and beta. Recently, it has shown that silicon
leaching can be also used to fabricate octadecasil nanocrystals
(10–25 nm) with a high degree of intercrystalline porosity
and a preserved structure.

Clathrasils, i.e.
zeolite-related materials consisting of window-connected
cages, are impenetrable to typical sorbate molecules such as
N2 or reactants such as hydrocarbons, and hence have no
prospective for catalytic applications. The zero-dimensional
character of these materials conditions the alkaline to operate
in a different manner, as the cages cannot be accessed.
Therefore, instead of attaining perforated crystals as in
channel-type zeolites, clathrasil crystals are fragmented and
peeled by the base, resulting in nanosized crystals. This widens
the scope of these compounds, opening room for application
as catalysts and/or catalyst supports

不好意思
这个意思是明确的
估计是作者创的词吧?不行你就直接理解为
octadecasil 纳米晶体

Clathrasils物质或材料吧

近来,已经有资料显示硅浸出也可以用来制作晶间孔隙度高、结构稳定的octadecasil 纳米晶体 (10–25 nm)。
