Novel Characterizations of Mechanical Properties for a Copper/Single-walled Carbon Nanotube Nanocomposite Synthesized by Laser Surface Implanting

C, 2020
In our previous studies, we have developed a wet process, denoted laser surface implanting (LSI), to synthesize a copper/single-walled carbon nanotube (Cu−SWCNT) metal nanocomposite as an implant onto the surface of a pure copper substrate.

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Impact of adhesive and photoactivation method on sealant integrity and polymer network formation

Brazilian Oral Research, 2012
We evaluated the influence of photoactivation method and hydrophobic resin (HR) application on the marginal and internal adaptation, hardness (KHN), and crosslink density (CLD) of a resin-based fissure sealant.

On the hardness tests.

Journal of Advanced Science, 1995
Hardness is defined as a scale to evaluate the resistance of an object against the force of an impression. Throughout their long history, hardness tests have acquired more and more applications in line with growing attention to the mechanical properties of industrial materials.

Dynamic nanoindentation testing: is there an influence on a material’s hardness?

Materials Research Letters, 2017
Modern nanoindentation devices are capable of dynamic experimentations, which allow us to exploit instrumented hardness tests extensively. Beside the assets of recording mechanical properties continuously over displacement, there are ongoing debates ...
