1. Transmission Electron Microscopy of 2D Materials : Structure and Surface Properties
Abstract : During recent years, new types of materials have been discovered with unique properties. One family of such materials are two-dimensional materials, which include graphene and MXene. These materials are stronger, more flexible, and have higher conductivity than other materials. As such they are highly interesting for new applications, e. READ MORE

2. 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

3. Mesoporous Silica Formed with Triblock Copolymers
Abstract : The formation of highly ordered mesoporous silica materials, using PEO-PPO-PEO amphiphilic triblock copolymers (so-called Pluronics) as structure directing agents, has been studied. The materials are formed through the addition of a silica source to a polymer solution of low concentration (2.5 wt ) under acidic conditions. READ MORE

4. Characterisation of Nickel-Based Superalloys Manufactued by Electron Beam Melting
Abstract : Nickel-based superalloys have been manufactured by electron beam melting (EBM). EBM is an additive manufacturing process for direct production of metal parts. The part is build up by successive melting of metal powder layers in a vacuum chamber using electron beam. READ MORE
