We report the functionalization of multi-walled carbon nanotube (MWCNT) electrodes by oxidative electropolymerization of pyrrole monomers bearing pyrene and N-hydroxysuccinimide groups. Both polymers were applied to the immobilization and electrical wiring of Trametes versicolor laccase via chemical grafting or non-covalent binding. A "pseudo" host-guest interaction of polymerized pyrene with a...

Acrylic acid and styrene were polymerized onto monodispersed Fe3O4 nanoparticles using a grafting copolymerization method. Aniline molecules were then bonded onto the Fe3O4 nanoparticles by electrostatic self-assembly and further polymerized to obtain uniform polyaniline/Fe3O4 (PANI/Fe3O4) nanoparticles (approximately 35 nm). Finally, monodispersed Ag/PANI/Fe3O4 nanoparticles were prepared by a...

Micropatterns of fibroblast and hippocampal neurons are generated on a single-layered graphene substrate. A large-area (1 cm × 1 cm) graphene film on Si/SiO2 is functionalized by surface-initiated ATRP of non-biofouling oligo(ethylene glycol) methacrylate, after grafting of the polymerization initiator bearing α-bromoisobutylate via photoreaction of the perfluorophenyl azide group. The microcon...

budding is a good method of propagation in the persian walnut (juglans regia l.)., however, success of budding is low due to higher root pressure as well as the presence of phenolic compounds in the xylem sap. this study was conducted to compare various budding methods and cut below budding :union: on two and three-year-old persian walnut under field conditions. the experiment was conducted bas...

Background: Surgical treatments of vitiligo are punch grafting, blister grafting, flip-top transplantation, split skin grafting, etc aiming at rebuilding of melanocytic population in those patients who do not respond to medical treatment . The objective of this study was determination of efficacy of blister grafting technique in the treatment of vitiligo. Methods: This study was done on 10 pati...

<p>Grafting with cayenne pepper rootstock (<em>Capsicum frutescens</em> L.) and red chili scion annum</em> L) can be used to improve the quality of plants. This study aims determine growth development plants from shoot grafting. The was carried out 3 treatments, namely kontrol (without grafting) (M<sub>o</sub>), treatment 1 (X<sub>1</sub>) fightin...

Twenty-five patients with chronic venous leg ulcers were treated in general practice by pinch grafting. Fifteen of the ulcers (60%) were completely healed one year after grafting. Prior to grafting 19 patients (76%) complained of daily pain in the ulcer. These patients experienced complete relief from pain after grafting. Pinch grafting is a simple, safe and effective therapy when applied in a ...

Fumed silica has found widespread application in industry due to variety of fascinating properties. Owing its specific manufacturing process, it consists finely dispersed particles and is featured with large surface area covered by profoundly reactive silanol groups which are available for chemical grafting. Spherical shape fumed lacking porosity provides a space-filling structure. These charac...
