Adsorption behaviour of methylene blue from aqueous solution on poly(ethylene terephthalate)-g-4-vinylpyridine/2-hydroxyethylmethacrylate fibers
(Walter De Gruyter Gmbh, 2007)
In this study, a novel fibrous adsorbent obtained by grafting 4-vinyl pyridine (4-VP)/2-hydroxyethylmethacrylate ( HEMA) comonomers onto poly ( ethylene terephthalate) ( PET) fibers was used for removal of methylene blue ...
4-vinylpyridine and 2-hydroxyethylmethacrylate monomer mixture graft copolymerization onto poly(ethylene terephthalate) fibers using benzoyl peroxide
(Springer, 2007)
Poly(ethylene terephthalate) (PET) fibers were grafted with 4-vinyl pyridine (4-VP) and 2-hydroxyethylmethacrylate (HEMA) using benzoyl peroxide (Bz(2)O(2)) as initiator in aqueous media. PET fibers were swelled in ...
Novel phosphazene derivatives: Synthesis, anisochronism and structural investigations of mono- and ditopic spiro-crypta phosphazenes
(Elsevier, 2007)
The reactions of hexachlorocyclotriphosphazatriene, N3P3Cl6, with N2O2-donor type coronands (diaza-crown ethers) 1-3 afford novel monotopic 4-7 and ditopic 8-10 spiro-crypta phosphazenes, respectively. It has been observed ...

A case report of an unusual formaldehyde exposure that had happened accidentally is described. A 54-year-old male ingested 10% formaldehyde and inhaled while vomiting and he developed cough, dyspnea and wheezing with ...
Turn-in folding of the cephalic portion of the lateral crus to support the alar rim in rhinoplasty
(Springer, 2007)
Background: The hypoplastic, weak lateral crus of the nose may cause concave alar rim deformity, and in severe cases, even alar rim collapse. These deformities may lead to both aesthetic disfigurement and functional ...
