A Detailed and Comparative Study on Conventional Sintering with Microwave Sintering and Vacuum Sintering of Y2O3-Al2O3-ZrO2 Ceramics

This chapter focused on comparative studies on conventional, microwave and vacuum sintering of alumina-added stabilised zirconia yttria (YSZ). When energy and time savings are involved, microwave sintering has been found to be the most effective sintering technique. In contrast to the conventionally sintered ones, microwave and vacuum sintered specimens display improved densification at lower temperatures.…

Recent Advancement of Precision Large-Caliber Slot Cutting of Sheet Steel Using Single-Mode Fiber Laser Radiation

We present the findings of an experimental and theoretical investigation into the properties and characteristics of large-caliber precision slot cutting of low-carbon steel sheets up to 10 mm thick by 1 kW single-mode fibre laser radiation. Slots with calibres from 20 to 60 (in some cases, up to 100) and widths up to around 60…

Focusing on the Quality of Potable Water Available to the Residents of Anambra State, Nigeria

Public pipe-borne water system had collapsed in Anambra state of Nigeria, for over fifteen years, challenging the residents of the state to resort to alternative sources of potable water, notably, boreholes. In this work, two boreholes each in nineteen communities, one from Aguluzigbo, in three local government areas (Anaocha, Awka-North, Awka-South) in the state were…
