Correction After the publication of this work [1], we noted that owing to an inadvertent mistake, the description of the chemotherapy schedule shown in the Methods was different from that shown in the Abstract and the duration of S-1 treatment in the initial chemoradiotherapy was inadequately described in Figure 1. Therefore, Methods and Figure 1 were modified accordingly. In the “Chemoradiothe...
Grit blasting is a low cost surface modification treatment widely used to enhance mechanical fixation of implants through increasing their roughness. As a result of the severe surface plastic deformation, beneath the surface it produces additional effects such as grain size refinement, work hardening and compressive residual stresses, which are generally evaluated with destructive techniques. I...
Surface hardening is a high temperature process that creates hard surface alloy layers that improve a metal’s wear resistance. The technique has been used for many years, however, precise control of the surface alloy composition is difficult since accurate control of the gas chemistry is challenging in these processes, which in turn makes it difficult to control the composition of the surface a...
