Abstract Background and Aim: One of the major problems with resin composite restorations is the weakness of bonding between the new and aged composites. Since appropriate micromechanical retention is necessary for the repair of aged resin composite restorations, the level of surface roughness after sandblasting can be influential in this regard. Considering the diverse composition of avail...

In this paper, scattering of a plane and monochromatic electromagnetic wave from a nano-wire is simulated using surface integral equations. First, integral equationsgoverning unknown fields on the surface is obtained based on Stratton-Cho surface integral equations. Then, the interaction of the wave with a non-plasmonic as well as a palsmonic nano-wire is considered. It is shown that in scatter...

There is a growing attention to enhance the performance of solid oxide fuel cell (SOFC) electrodes through incorporation nano-catalyst materials within electrodes’ active sites. In this study, we report technique for increased efficiency and microstructural control infiltration process polymerized norepinephrine (pNE) treatment. Nano-CeO2 catalysts were incorporated both commercial anode-suppor...

Covalently functionalized multi-walled carbon nanotubes (MWNTs) were prepared by grafting well-defined thermo-responsive poly(N-isopropylacrylamide) (PNIPAM) via click reactions. First, azide-terminated poly(N-isopropylacrylamide) (N3-PNIPAM) was synthesized by reversible addition fragmentation chain-transfer (RAFT) polymerization, and then the N₃-PNIPAM moiety was connected onto MWNTs by click...

Polymers are being used extensively in drug delivery due to their surface and bulk properties. They are being used in drug formulations and in drug delivery devices. These drug delivery devices may be in the form of implants for controlled drug delivery. Polymers used in colloidal drug carrier systems, consisting of small particles, show great advantage in drug delivery systems because of optim...

Photocatalysis has emerged as a promising technique owing to its valuable applications in environmental purification. With the demand of building effective photocatalyst materials, semiconductor investigation experienced a developing process from simple chemical modification to complicated morphology design. In this review, the general relationship between morphology structures and photocatalyt...

The prospect of nano-photocatalysts in cementitious systems is promising but the engineering application still limited, caused by insufficient insights on durability properties during service. Mortars with different binders and photocatalysts are prepared characterized to investigate deterioration mechanisms self-cleaning performance upon simultaneous hydration/carbonation. Alterations driven c...
