A platform technology based on inorganic/organic nanoparticles for carrying drugs could be of enormous potential benefit in treating cancer. Surface modification the with pH-responsive and biocompatible polymers can improve selectivity targeting toward tumor cells. Polyethylene glycol (PEG) its derivatives being present surface enhance ability to tailor nanomaterial hydrophilicity resist adhesi...

In this paper, the free vibration analysis of sandwich micro beam with piezoelectric layers based on the modified couple stress and surface elasticity theories are investigated. The Hamilton’s principle is employed to derive the sandwich micro beam with piezoelectric based on modified couple stress theory incorporating with Gurtin- Murdoch surface theory. The generalized differential quadrature...

Cravy Brush is an interactive toothbrush attachment that helps young children (3-8 years old) develop a daily habit of brushing teeth. The attachment displays an interactive game that provides real-time visual and auditory feedback. In addition to feedback, Cravy Brush also provides virtual rewards when children brush properly. Alarm feature calls for children to brush their teeth twice a day a...

Hydrogels, especially double-network hydrogels, are attractive candidates as load-bearing biomaterials, e.g., tissue-engineering supports for articular cartilages and bones. In this study, we describe the modification of a hydrogel by introduction third monomer, N-[3-(dimethylamino)propyl]methacrylamide, to network system, which serves reactive site subsequent interfacial reactions surface-init...

We have investigated SiC/oxide interface structures by the use of spectroscopic ellipsometry. The depth profile of the optical constants of thermally grown oxide layers on SiC was obtained by observing the slope-shaped oxide layers, and the results suggest the existence of the interface layers, around 1 nm in thickness, having high refractive index than those of both SiC and SiO2. The wavelengt...

fiber metal laminates (fmls) are new composite materials consisting of thin metal layers and high strength composite layers. arall (aramid aluminum laminate) is a family of the fml that consists of thin aluminum sheets along with kevlar/epoxy composite layers. this material has many advantages such as light weight, excellent corrosion, fatigue and impact resistance. since, arall is a new materi...

Background: Curcuma longa generally known as turmeric includes curcuminoids and sesquiterpenoids as components, which are known to have antioxidative, anticarcinogenic, and anti-inflammatory activities. Iron, magnetite, and hematite as a micronutrient play an important role in physiological and chemical processes. Chitosan is a natural polymer derived from chitin and is recognized as versatile ...

Abstract Silicone elastomers-based materials have been extensively involved in the field of biomedical devices, while their use is extremely restricted due to poor surface lubricity and inherent hydrophobicity. This paper describes a novel strategy for generating robust layered soft matter lubrication coating on polydimethylsiloxane (PDMS) silicone elastomer, by entangling thick polyzwitterioni...
