Hierarchical micro-mesoporous ZSM-5 (MFI type) zeolite was synthesized by using corn plant stem pith powder from agricultural waste as hard template under simple hydrothermal method. The additional porosity generated this into the zeolites precursor gel yielded hierarchical (C-ZSM-5). Conventional micro porous (ConvZSM-5) also prepared same procedure without adding to compare catalytic performa...

The pyrroloindoline alkaloids are a structurally diverse family of biologically active natural products, which include compounds such as hodgkinsine (1), naseseazine A (2), and gliocladine C (3) 3 (Fig. 1). As a result of their compelling bioactivities and fascinating structures, this family of alkaloids has been the subject of intense research and has inspired the development of a variety of n...

Pyromellitic acid diimides are not as chemically unreactive conjecturable (and presupposed) from their numerous applications electron acceptor units or carriers in molecular donor–acceptor dyads triads. Similar to the corresponding phthalimides, electronically excited pyromellitic oxidize alkyl carboxylates aqueous solution via intermolecular transfer (PET) processes, which eventually results r...
