This work investigates the effects of cerium oxide (CeO 2 ) coatings on the response of osteoblasts to H 2 O 2 -induced oxidative stress. The results show that the coatings have a protective effect, promoting both osteoblast growth and differentiation. This indicates that the CeO 2 coating reduces the production of reactive oxygen species in H 2 O 2 -treated osteoblasts. These coatings, with their antioxidant properties, appear quite promising for bone regeneration.

This study shows that the osteogenic abilities of calcium silicate based coatings can be improved through nanotopographical surface modifications and the addition of bioactive trace elements. CaSiO 3 powders were deposited on titanium substrates by atmospheric plasma spraying and the topography and composition of the resulting coatings were modified by hydrothermal treatments in deionized water and in aqueous solutions of Sr(NO 3 ) 2 . Bone marrow stem cells were cultured on treated and untreated coatings. The cells spread further on treated surfaces and were found to be relatively larger in size than the cells on untreated surfaces. Calcium silicate coatings treated in the strontium-containing solution showed the best overall improvement in terms of bone cell growth and differentiation.

Aluminum-copper alloys are popular for many applications that take advantage of the combination of properties in the alloys. This paper describes the use of multiple advanced failure analysis tools to analyze the physical and chemical properties of Al-Cu alloy thin films.

This paper presents a case study on via high resistance issue. A logical failure analysis process EDCA ( E ffect, D efect, C ause, and A ction) is successfully applied to find out the failure mechanism, pinpoint the root cause and solve the problem. It sets up a very good example of how to do tough failure analysis in a controllable way.
