This research reports the synthesis of stable anion exchange membranes (AEMs) from brominated poly (2,6-dimethyl-1,4-phenylene oxide) (BPPO) and triethylamine (TEA) for desalination applications. The successful synthesis ...
On generalized Littlewood–Paley functions
(
Springer-Verlag Italia s.r.l.
, 2018 , Article)
We study the Lp boundedness of certain classes of generalized Littlewood–Paley functions S(f). We obtain Lp estimates of S(f) with sharp range of p and under optimal conditions on ?. By using these estimates along with an ...
