Accelerated Neutral Atom Beam processing of medical devices enhances tissue integration while reducing bacterial attachment

Khoury J., Phok B., Kirkpatrick S., Walsh M., Shashkov D., Exogenesis Corp, US

Accelerated Neutral Atom Beam (ANAB) technology is a low energy accelerated particle beam gaining acceptance as a tool for nano-scale surface modification of implantable medical devices. ANAB is created by acceleration of 2. METHODS neutral [...]

Enhancement of pure titanium localized corrosion resistance by chemical oxidation

Prando D., Brenna A., Diamanti M.V., Ormellese M., Pedeferri M.P., Politecnico di Milano, IT

Titanium and its alloys are widely appreciated for their high corrosion resistance in environments that are critical even for high-end stainless steel (duplex UNS S31803 and UNS S32750), such as concentrated chlorides [1]. This resistance [...]

Grow of stem cells on chemical-laser generated titanium cobalt shape memory alloy nanoparticles

Karami A., Materials and Energy Research Centre, IR

In this research nanoparticles are fabricated using a method that is a combination of chemical and femtosecond laser ablation methods. The resulting nanoparticles are used to coat glass substrates in order to test the biocompatibility [...]

Ti-based nanocrystallites formation by high-energy milling

Kwon H., Jung S., Cho S.W., Kil D.S., Kim J., Roh K.M., Lim J.W., Korea Institute of Geoscience and Mineral Resources, KR

There are many researches for the solid-solution to prepare the materials with the properties which pure materials do not have. However, basically, it was difficult to synthesize the solid-solution phase because of high activation energy [...]

Novel Organofunctional Silane Coatings on Silica-Coated Ti

Matinlinna J.P., Tsoi J.K.H., The University of Hong Kong, HK

This in vitro study characterizes a developed novel silane system method to produce coatings on Ti. Hydrophobic coatings are needed in prosthetic dentistry to promote durable adhesion between luting resin cements and coated Ti surfaces. [...]

Tunable Wetting of Titanium and Gold Based Wicking Materials

Ding C., university of california, santa barbara, US

We quantitatively report the experimental super-wetting results of wicking materials fabricated with bulk titanium micromachining, nano-scale surface modification and gold plating techniques. The results show all the four samples are completely wettable with water but [...]

Diamond-Hardfaced TiC/Ti Composite for Submersible Pump Bearings in Geothermal Systems

Voronov O.A., Kear B.H., Diamond Materials Inc., US

Renewable energy sources include electrical generators driven by steam from geothermal sources. Typically, the bearings of submersible pumps used in geothermal systems are hardfaced with WC/Co and WC/CoCr composites. To enhance bearing performance, we have [...]

Morphological variations on titanium by AC anodizing

Diamanti M.V., Ormellese M., Pedeferri MP., Politecnico di Milano, IT

Besides the widely investigated photoinduced properties of its oxides, a primary branch of application of anodized titanium is the production of biomedical implants, where a controlled roughness can lead to improvements in cell adhesion and [...]

Respiratory Syncytial Virus Inhibition by Gold and Titanium Nanoparticles

Vig K., Boyoglu S., Rangari V., Pillai S., Singh S.R., Alabama State University, US

Respiratory Syncytial Virus (RSV) is the leading cause of severe respiratory illnesses including bronchiolitis and pneumonia in young children. The RSV surface proteins F (fusion) and G (attachment) are major targets for vaccine development against [...]

Nanocomposite Contact Material for MEMS Switches

Ding C., MacDonald N.C., university of california, santa barbara, US

This work reports the development of a nanostructured composite contact material for improving the contact reliability of MEMS switches. The nanocomposite material was integrated into a bulk titanium MEMS (BT-MEMS) switch which was fabricated using [...]
