Ahmed, E., Henein, H., Qureshi, A., Liu, J.
Downhole tools made of dissolvable alloys (DAs) are getting more attractive, especially with the difficulties that arise from drilling wellbores with longer lateral distances. To date, most of the DAs are based on Al alloys (AAs) or Mg alloys, which offer undesirable mechanical properties. This...

Vitrification of articular cartilage (AC) could enhance tissue availability but requires high concentrations of cyroprotective agents (CPAs). This study investigated relative injuries caused by commonly used CPAs. We hypothesized that the in situ chondrocyte dose–injury relationships of five...

Poor control of hot strip mill loopers degrades strip width and gauge, and may even lead to mill breakdowns due to instability. In this study, dynamics of the looper-strip system and the control challenges it poses are discussed, and covariance control theory is applied to variance control design...

Ren, T., Mohammadijoo, M., Wiskel, J.B., Lazor, R., Willett, E., Ivey, D.G., Henein, H.
The pipeline industry has undertaken an essential upgrade of well established X70 pipeline steel in heavy gauge pipes to fill the demand of increased operating pressures. A developed welding process, cold wire tandem submerged arc welding (CWTSAW), with improved deposition rate and travel speed...

Bogno, A.-A., Valloton, J., Henein, H., Ivey, D.G., Locock, A.J., Gallerneault, M.
This work addresses the microstructures and mechanical properties of Al-4.5 wt% Cu alloys containing 0.1, 0.2 and 0.4 wt% Sc that were solidified under low cooling rate conditions (< 1ºC/s) and then heat treated. The samples were solidified in a differential scanning calorimeter before being heat...

Feng, Lin, Chen, Ming, Zheng, Fei, Niu, Meng-Si, Zhang, Xuehua, Hao, Xiao-Tao
A novel nanocomposite of P3HT and Ag nanoparticles (Ag-P3HT) has been synthesized by laser ablation. The fluorescence wavelength of the nanocomposite can be tuned by varying the ablation duration. The steady-state emission maximum at 580 nm for pristine P3HT shows significant blueshift to...
