High-quality ZnO nanobelts were synthesized through introducing an unsteady state in the vapour transport process and their applications in novel Schottky solar cells were demonstrated by contact-printing the ZnO nanobelt network onto a pre-patterned Pt electrode followed by the deposition of a Ti/Au electrode.

The induced transient viscous flow due to a suddenly stretched surface is studied. After a similarity transform, the unsteady Navier–Stokes equation is solved by several methods, including perturbation for small times, numerical integration, and asymptotic analysis for large times. It is found that the validity of the small-time series can be greatly extended and the approach to steady state is...

A typical characteristic of refrigeration compressor performance tests is their long duration. A reduction in the time periods related to this activity can be achieved using unsteady-state data analysis. This paper presents an original approach to predicting compressor performance using Bayesian networks and a hybrid Fuzzy–Bayesian network. All analysis was performed using real test data. 2011 ...

The necessity of measuring permeability is encountered in number applications and some them have adequate measurement techniques available. However, the fields freeze drying, composite scaffolds, 3D printed materials, etc., sample materials unique shapes sizes, which disables use standardized equipment. Hence, a novel method was developed to determine material by analyzing high frequency unstea...
