Polyetheretherketone (PEEK): a contemporary modality in cranio maxillofacial reconstruction

Advances in Medical, Pharmaceutical and Dental Research, 2022
This descriptive review focuses on the evolution of polyetheretherketone [PEEK] for the reconstruction of cranio- maxillofacial defects. This treatment modality is now trending and growing throughout the different aspects of the oral  and maxillofacial specialty to include customized patient specific implants for reconstructive surgeries, and a ...

Fast modal wave-front reconstruction [PDF]

, 2004
In this project I apply the concepts and techniques learned in Applied Computational Harmonic Analysis (ACHA) to my research. I am currently developing fast wave-front reconstruction techniques for high-order Adaptive Optics systems. The fast reconstruction technique which we plan on using is based on the DFT.

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

Advanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Simulation‐Based Analysis of Insert Pull‐Out in Nickel‐Polyurethane Hybrid Foams Using CT‐Derived Geometries

Advanced Engineering Materials, EarlyView.
CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Influence of TiC and TiN Ceramic Reinforcements on the Microstructure, Thermal Expansion Behavior, and Tensile Properties of Invar 36 Manufactured by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...
