Calcium phosphate cements (CPC) are well-established materials for the repair of bone defects with excellent biocompatibility and bioactivity. However, brittleness and low flexural/tensile strength so far restrict their application to non-load bearing areas. Reinforcement of CPC with fibers can substantially improve its strength and toughness and has been one major strategy to overcome the pres...

Waste plastics may be an environmentally friendly alternative to natural aggregates for concrete manufacture. However, the inferior bond strength between waste plastic and cement matrix greatly limits uses of engineering designs applications. Herein, ethylene–vinyl acetate (EVA) nanosilica (nS) were jointly employed enhance matrix-aggregate interactions in cementitious composites with recycled ...

This research work was carried out to establish an appropriate theoretical model to describe elastic properties of cementitious composites. The elastic properties include modulus of elasticity, modulus of rigidity, bulk modulus and Poisson's ratio. A literature search was carried out to gain information about existing analytical models in order to predict elastic behavior of composites. Analysi...

in the present study, modelling and vibration analysis of carbon nanotubes/ fiber/ polymer composite microplates are investigated. the governing equations of the carbon nanotubes/ fiber/ polymer composite microplates are derived based on first order shear deformation plate theory, rather than other plate theories, due to accuracy and simplicity of polynomial functions. the modified couple stres...

a pebax-nano zeolite x mixed matrix membrane was fabricated and operationally characterized using single gas (co2) permeation. x-ray diffraction (xrd) analysis was used to study the arrangement of polymer chains of mixed matrix membrane. the membranes were characterized by scanning electron microscopy (sem) to study cross-sectional morphology. the single gas permeability were carried out for ne...
