Carbon nanotubes (CNT) were dispersed into homemade silicone–polyurethane (SPU) resin in order to enhance their mechanical and anticorrosion ability. Before mixing with SPU, CNT modified by four different approaches improve dispersion the surface of covered SiO2–TiO2 nanoparticles, -NH2 groups, epoxy groups or isocyanate respectively. The structures CNTs checked XRD, FTIR, SEM. After being SPU ...

An immunoperoxidase method for the demonstration of carcinoembryonic antigen (CEA) in tissues was applied to formalin-fixed paraffin embedded and glutaraldehyde-fixed resin sections of normal human small intestine. CEA could easily be demonstrated coating the surface of the small intestine, lining the crypts, and in goblet cells, indicating its presence there in considerable concentration. At t...

In this study some new fluorophore-enriched polymers were synthesized using the reactions of bisphenol-A resin and fluorescein in the presence of PVA or polyetherdiamine as hardener. The structures of polymers were elucidated by IR, UV and fluorimetry spectrometry. Polymers applied as coating on water are diffusible surface. The results of fluorimetry on penetrated water containing fluorescent ...

This study evaluated the effect of multiple consecutive adhesive resin coatings of adhesive bonded to human dentin on nanoleakage and resin-dentin bond strength. Resin bonded dentin specimens were prepared using a total-etch adhesive (One-Step Plus) applied as multiple consecutive coating, or using two self-etch adhesive systems (iBond or Fluoro Bond). For the total-etch adhesive, resin applica...

Increased competition on the tissue market forces tissue makers to continuously raise their product quality and increase their operating efficiency. The creping process and the conditions on the Yankee cylinder are the key factors in the production process and they therefore need to be kept under good control in order to maintain a high and uniform quality. Due to evaporation, dissolved substan...

UNLABELLED To evaluate bond strengths of different resin cements to two aluminum oxide-based ceramics. METHODS One hundred ten ceramic cylinders were produced and given four different surface treatments. Resin cement cylinders were then bonded to the ceramic cylinders using different resin cements and the bond strength was determined by shear testing to the breaking point. We were thus able t...

In this study, Damar Batu (DB) − a novel biomaterial− is evaluated for its potential application in pharmaceutical coating. DB is a whitish to yellowish resin, characterized initially in terms of solubility, acid value, molecular weight (Mw), polydispersity index (Mw/Mn) and glass transition temperature (Tg). Neat plasticized films of DB are investigated for mechanical, water vapor transmission...

In this work, separation performance of supported carbon membranes produced from Novolac Phenolic resin as the main precursor and carbon nanotubes as nanofiller were investigated for separation of CO2 from N2 and CH4. Supports were produced by carbonization of Novolac Phenolic resin-activated carbon mixture, and selective layer was coated by dip coating of prepa...
