The self-assembly of amphiphilic (porphyrin)Sn 1 in an aqueous Pluronic F127 media results in the formation of narrowly dispersed nanowires. Variation of aqueous Pluronic concentrations allows for a systematic variation of porphyrin nanowire lengths while keeping their widths constant. These nanowires can be further assembled into secondary macroscopic columns.

Because of high occurrence of side effects of conventional anticancer drugs, new therapies have been widely studied, such as the use of non-usual molecules and the association with nanomaterials. In this context, sildenafil is a molecule that has been lately considered as a co-adjuvant in cancer therapy because it inhibits an enzyme with a potential role in tumor progression, phosphodiesterase-...

mesoporous  mgo  microstructures  were  synthesized  using magnesium  acetate  tetrahydrate,  ammonium  oxalate  monohydrate and  pluronic  f127  via  heating  at  40  °c  for  24  h  and  subsequent calcination. the mesoporous structure of magnesium oxide with the specific  surface  area  of  47m2/g,  pore  volume  0.30  cm3/g  and  the average pore size 24 nm is produced. according to xrd stu...

The aim of the present work was to investigate poloxamer 188 (F-68) modified montmorillonite (Mt) clay as an oral drug delivery vehicle for in vitro release of anti-inflammatory drugdiclofenac sodium (DS). The clay (Mt) was treated with F-68 and the synthesized modified Mt, (F-68-Mt) was characterized by X-Ray diffraction (XRD) studies (which confirmed the intercalation of F-68 in the clay inte...

Preparation of well-ordered continuous mesoporous carbon films without the use of an intermediate inorganic template was achieved by spin coating of a thermosetting phenolic resin, resorcinol/phloroglucinol/formaldehyde, and a thermally-decomposable organic template, Pluronic F127 (PEO106–PPO70–PEO106). The carbon films were deposited onto silicon, platinum/ silicon, copper, glass, and quartz s...

Mumford has constructed 4-dimensional abelian varieties with trivial endomorphism ring, but whose Mumford–Tate group is much smaller than the full symplectic group. We consider such an abelian variety, defined over a number field F , and study the associated p-adic Galois representation. For F sufficiently large, this representation can be lifted to Gm(Qp)× SL2(Qp) . Such liftings can be used t...
