Web1 day ago · It is well known that an excessive loss of crystallinity and microporosity during the alkaline treatment of zeolites can have negative effects on their potential use as a catalyst. Therefore, it is important to understand the acid properties of zeolites, as both acidity and accessibility of active sites influence their catalytic performance. WebAug 14, 2024 · However, we recently reported that gas transport properties were independent of PLA crystallinity (Komatsuka et al. 2008; Komatsuka and Nagai 2009; Sawada et al. 2010).This result suggests that gas transport properties are strongly affected by the size and distribution of the crystalline phase rather than by the polymer … imprimante brother ne se connecte pas
