1. A TEM Investigation of Contact between Nanoparticles
Abstract : Interaction between nanoparticles (1~100nm) provides us with answers to fundamental questions in many important applications e.g. adhesion, friction, and cold welding. The attractive force arises from the reduction of the total free surface and thus the total surface energy due to the formation of a boundary between the contacting particles. READ MORE

2. Toxicity of metal containing micro- and nanoparticles : studies from an inhalation perspective
Abstract : Particles in urban environments have for a long time been associated with different health problems and diseases, such as worsening of asthma and chronic obstructive pulmonary disease as well as cancer and cardiovascular diseases. In addition, metal containing particles present in occupational settings and industries, particularly particles produced during welding, have been linked to several adverse health effects. READ MORE

3. Exploring toxicity and fate of metal-based particles in the lung : from mechanistic screening to lung deposition modelling
Abstract : We are all exposed to small particles in the air that we breath and some of them will contain metals in a dose and form that may be harmful. In addition, the field of nanotechnology holds great promises, but an increased production of nanoparticles leads to a higher risk of exposure. READ MORE

4. Carbon nanofiller reinforced UHMWPE for orthopaedic applications : optimization of manufacturing parameters
Abstract : Polymer composites research designed for orthopaedic applications are commonly focused on Ultra high molecular weight polyethylene (UHMWPE) reinforced by a variety of different nanoparticles. However, the high melt viscosity of UHMWPE renders conventional melt mixing techniques impossible for composite manufacturing. READ MORE
