2014 The effect of temperature on the aggregation behaviour of nonionic surfactants in aqueous solution has been investigated by means of transient fluorescence probing (intramicellar excimer formation by pyrene). For surfactants of the C12H25En type (E = ethyleneoxide group, n = 6, 8, 9) the number average aggregation number N of the micelle is nearly independent of the temperature T when T is...

We characterize the Schauder and unconditional basis properties for Haar system in Triebel–Lizorkin spaces $$F^s_{p,q}({{\mathbb {R}}}^d)$$ , at endpoint cases $$s=1$$ $$s=d/p-d$$ $$p=\infty $$ . Together with earlier results Garrigós et al. (J Fourier Anal Appl 24(5):1319–1339, 2018) Seeger Ullrich (Math Z 285:91–119, 2017), this completes picture such scale, complements a similar study Besov ...

The classical method of producing cellulose oligomers through hydrolysis microcrystalline (MCC) in phosphoric acid has been re-examined. Hydrolysis products are fractionated by precipitation to yield two types with different average degrees polymerization (DP). number- and weight-averaged molecular weights the lower DP fraction 1339 g/mol 1388 respectively, corresponding a polydispersity index ...
