Modified halloysite nanotubes (HNTs-Cl) were synthesized by a coupling reaction with (3-chloropropyl) trimethoxysilane (CPTMS). The incorporation of chloro-silane onto HNTs surface creates HNTs-Cl, which has great chemical activity and is considered good candidate as an active site that reacts other molecules in order to create new materials applications engineering nanotechnology. value this w...

In this research, a novel method is reported for the surface grafting of n-vinylcaprolactam as a thermosensitive agent and 3-allyloxy-1,2-propandiol with an affinity toward ceftriaxone onto modified magnetic nanoparticles by 3-mercaptopropyltrimethoxysilane. The grafted nanoparticles were characterized by Fourier Transform Infrared Spectroscopy, Elemental Analysis, and Vibrating Sample Magnetom...

in order to study the effect of rootstock, scion and some methods of grafting and budding to achieve the best methods of grafting in pomegranate, split factorial experiment was conducted in a completely randomized design in march 2013 in greenhouse at the agricultural college of vali-e-asr university of rafsanjan. factors included rootstock, scion, and methods of grafting and time of grafting. ...

Background: Autogenous osteochondral grafting of articular defect in weight-bearing surface of large joints has proven to be a proper biomechanical and physiological solution for localized full-thickness defects.Objective: To study the gross and histopathological results of mosaicplasty in an animal model (sheep’s medial femoral condyle), evaluating the factors of defect and graft size, assessi...

A combined surface treatment (i.e., surface grafting and a layer-by-layer (LbL) approach) is presented to create advanced biomaterials, i.e., 3D poly(l-lactide) (PLLA) microsphere scaffolds, at room temperature. The grafted surface plays a crucial role in assembling polyelectrolyte multilayers (PEMs) onto the surface of the microspheres, thus improving the physicochemical properties of the 3D m...

The common problems seen in distal femoral fractures are communition, articular surface involvement, fractures in multiple planes and bone loss in compound fractures. They present a challenge to the surgeon to achieve stable fixation and union. With different methods of internal fixation available, the common complications encountered with distal femoral fractures are malunion, varus collapse, ...

A novel approach was developed for the synthesis of tethered polymer layers with thickness and grafting density gradients. Poly(glycidyl methacrylate) (PGMA) was employed as a primary anchoring layer to attach the polymer chains to the surface of a silicon wafer. A linear temperature gradient heated stage was used for the generation of a gradual variation in the thickness of the anchoring PGMA ...
