There is an increasing interest in using indoor photovoltaic (IPV) devices to power Internet of Things applications, low power communications, and indoor environmental sensing. For the commercialization of IPV technologies, device performance measure

This paper describes and evaluates a unit (module), the design of which addressed the problems of running group work in Higher Education. The design process began by consulting students and colleagues and with a literature review. This led to the ide

A study of alloying effects in Cr-V rail steels has been carried out to determine the microstructural strengthening mechanisms. The laboratory steels investigated were based on the commercial 1 pct Cr rail steel chemistry (0.75C−0.8Mn−1 .25Cr−0

Shatter cracks form in hot-rolled rail steels when hydrogen atoms diffuse into sinks, change to molecular hydrogen gas and exceed a critical pressure. Cracking can occur at temperatures below 200°C. Hydrogen degassing to “safe” levels, i.e. belo

Microstructural inhomogenities or ‘streaks’ of lower bainite were found in the webs of experimental ingot and continuously cast Cr–Mo steel rails. The effect of these inhomogenities on the fracture toughness behaviour of rail web steels was inv

The composition of two commercial rail steels (1% Cr and Cr-Cb) were modified by addition of vanadium and nitrogen. The microstructures and mechanical properties of the steels were determined. The results indicate that addition of 0.1% vanadium to th
