N-halamines serve as important antimicrobial agents. Development of this class of compounds has been shown to provide benefits especially from a biocidal point of, vie w. A novel s-triazine-based N-heterocycle, dichloro-m-aminophenyl-hydantoinyl-s-triazine (DAPHT), which could be rendered antimicrobial through exposure to diluted chlorine bleach, was synthesized and characterized by H-1 NMR, C-13 NMR, and FT-IR. A finishing method was used to apply the N-halamine precursor onto cotton fabric, and the optimum conditions for finishing were investigated. The DAPHT-treated cotton fabric had durable antimicrobial properties up to 50 standard washing cycles and was rechargeable under normal laundry/bleaching conditions. The antimicrobial efficacy against Gram-positive and Gram-negative bacteria was demonstrated.


Preparation and labeling of surface-modified magnetoferritin protein cages with a rhenium(I) carbonyl complex for magnetically targeted radiotherapy
Aslan, Tugba Nur; Asik, Elif; Volkan, Mürvet (Royal Society of Chemistry (RSC), 2016-01-01)
New rhenium radiolabeled compounds are of general interest due to their nuclear characteristics which allow radiotherapy and in situ monitoring of tumor uptake. Biocompatible magnetic nanoparticles capable of transporting radionuclides, providing MRI contrast agent properties for imaging and a therapeutic effect in the target tissue simultaneously, are highly desirable. Herein we describe the preparation of magnetoferritin samples, and their labeling with rhenium in the form of the low oxidation state rheni...
Utilization of pretreated molasses for serine alkaline protease production with recombinant Bacillus species
Calik, G; Pehlivan, N; Kalender, N; Ozdamar, TH; Çalık, Pınar (Informa UK Limited, 2003-05-01)
Recombinant Bacillus amyloliquefaciens, Bacillus cereus, Bacillus subtilis , and Bacillus licheniformis were used for the production of serine alkaline protease (SAP) utilizing chemically and/or physically pretreated molasses. The highest enzyme activity was obtained with r- Bacillus subtilis , with the complex medium involving physically treated molasses having 20 kg m(-3) initial sucrose concentration in small-scale, agitation- and heating rate-controlled bioreactors at t=63 h. Effects of oxygen transfer ...

Liposome surface modifications serve great potential applications of liposomes, for instance, increasing stability, bioactive liposome conjugates, and targeted drug, gene, and image agent delivery. In this study, novel targeted lipopolymers, peptide 18/peptide 563-poly(2-ethyl-2-oxazoline)-dioleoylphosphatidyl-ethanolamine (P18/P563-PEtOx-DOPE), have been demonstrated to be successfully synthesized. The structures of P18/P563-PEtOx-DOPE were confirmed by FT-IR spectroscopy, GPC, and(1)H-NMR. In this strateg...
Development of a synthetic strategy for Water soluble tripodal receptors: Two novel fluorescent receptors for highly selective and sensitive detections of Fe3+ and Cu2+ ions and biological evaluation

A general synthetic strategy is developed to synthesize water soluble receptors by employing tripodal system based on a cyclotriphosphaze platform. The developed model is successfully synthesized and characterized by using elemental analysis, FT-IR, MALDI-TOF, H-1 NMR, C-13 NMR and P-31 NMR techniques. The fluorescence sensing performance of prepared water soluble tripodal systems were evaluated by UV/Vis and fluorescence spectroscopies. According to obtained results, two novel water-soluble sensing platfor...
Effects of mixing sequence on epoxy/polyether polyol/organoclay ternary nanocomposites
Isik-Gulsac, Isil; YILMAZER, ÜLKÜ; Bayram, Göknur (Informa UK Limited, 2020-09-01)
The effects of mixing sequence of the polyether polyol and curing agent (triethylenetetramine) on mechanical and thermal properties and morphology of epoxy/polyether polyol/organoclay ternary nanocomposites are investigated in this study. The polyether polyol domain size data are relatively unchanged with mixing order both in epoxy/polyether polyol blends and in ternary nanocomposites. Generally, impact strength data of the ternary nanocomposites prepared by the second addition order are higher than the one...
