There are many medical conditions like osteoporosis, tumor, or osteonecrosis that weaken the structural strength of the vertebral body and prone it to fracture. Percutaneous vertebral augmentation that is usually applied by polymethylmethacrylate is a relatively safe, effective, and long lasting procedure commonly performed in these situations. In this paper, we updated a review of biomechanics...

Recently, the studies on lightweighting have gained significant importance due to requirements such as energy efficiency and sustainability. Polymer materials are a group of that frequently used for this purpose. This study investigated effects laser power, cutting speed focal point kerf width, which most effective process parameters in Polymethylmethacrylate, low-cost polymer material, using R...

Graphene was first identified in 2004, and it has remarkable properties. Atoms of are very tightly bonded so, like carbon nanotubes, which makes super-strong, even more, potent than diamond. Moreover, good Heat conductivity, Electrical optical Application the dental field, especially prosthodontics, includes addition to Polymethylmethacrylate improving its In removable implant prosthodontics la...

Nanoscale science and technology has today mainly focused on the fabrication of nano devices. In this paper, we study the use of lithography process to build the desired nanostructures directly. Nanolithography on polymethylmethacrylate (PMMA) surface is carried out by using Atomic Force Microscope (AFM) equipped with silicon tip, in contact mode. The analysis of the results shows that the ...
