Journal ArticleDOI
Making porous conductive carbon films with unbalanced magnetron sputtering
TL;DR: In this article, the porosity control of conductive carbon films was investigated by using unbalanced magnetron sputtering (UBMS), which can be tuned to have porosity ranging from amorphous to porous by varying the working pressures from 3 to 140 mTorr.
Journal ArticleDOI
Application of a new mechanical properties microprobe to study hardness of eroded bovine enamel in vitro
TL;DR: Shorter immersion times than previously used can be applied in dental erosion studies in vitro, and enamel softening was found to be significant after 5 min immersion in both acidic drinks, while 1 min immersion did not cause softening.
Journal ArticleDOI

TL;DR: In this article, a physical and electrochemical study of application-specific carbon nanofibers grown from Pt-catalyst layers is presented, showing that the material shows two separate linear ranges for hydrogen peroxide reduction: 1 −100 μM and 100 −1000 μM with sensitivities of 0.432 μA μM−1 cm−2 and 0.257 μA −1 cm −2 with a 0.21 μM limit of detection.
Journal ArticleDOI
Hybrid X-ray Spectroscopy-Based Approach To Acquire Chemical and Structural Information of Single-Walled Carbon Nanotubes with Superior Sensitivity
Sami Sainio,Niklas Wester,Charles J. Titus,Yongping Liao,Qiang Zhang,Dennis Nordlund,Dimosthenis Sokaras,Sang Jun Lee,Kent D. Irwin,William B. Doriese,Galen C. O'Neil,Daniel S. Swetz,Joel N. Ullom,Joel N. Ullom,Esko I. Kauppinen,Tomi Laurila,Jari Koskinen +16 more
TL;DR: In this paper, a hybrid X-ray-based study retrieving this hard-to-access chemical and structural information of application-ready ferrocene-grown single-walled carbon nanotubes and their nitric acid- and oxygen plasma-treated versions is presented.
Journal ArticleDOI
Experimental design and modelling in the investigation of process parameter effects on the tribological and mechanical properties of r.f.-plasma-deposited a-C:H films
TL;DR: In this paper, the effect of deposition parameters on the mechanical and tribological properties of the a-C:H films was analyzed using an experimental design method and statistical analysis and modelling to analyse the results.
