Reuse Technology of High Purity Silicon Sludge

Perforated diode neutron detector modules fabricated from high-purity silicon

Compact neutron detectors are being designed and tested for use as low-power real-time personnel dosimeters. The neutron detectors are pin diodes that are mass produced from high-purity Si wafers. Each detector has thousands of circular perforations etched vertically into the device. The perforations are backfilled with LiF to make the pin diodes sensitive to thermal neutrons. The prototype dev...

Sanitisation of Faecal Sludge by Ammonia Treatment Technology for Safe Reuse in Agriculture

Faecal sludge contains valuable plant nutrients and can be used as a fertiliser in agriculture, instead of being emitted as a pollutant. As this involves a risk of pathogen transmission, it is crucial to inactivate the pathogens in faecal sludge. One treatment alternative is ammonia sanitisation, as uncharged ammonia (NH3) inactivates pathogens. The aim of this thesis was to study how the patho...

Paper Sludge Reuse in Lightweight Aggregates Manufacturing

The lightweight aggregates used by the civil engineering market are sintered at a high temperature, about 1200 °C. In times of high energy prices and regulation of carbon dioxide emissions, lightweight aggregate products of the high-temperature process in sales marketing are not readily accepted. This study developed a sintered-type paper sludge lightweight aggregate. In order to reduce energy ...

Object Technology and Reuse:

Object-oriented (OO) technology represents one of the most important innovations in software process technology to emerge in the last twenty years. Beginning in the early 1990’s, we performed four longitudinal cases studies of early adoption of OO to gain an understanding of what challenges early adopters face, and what strategies can be used to overcome those challenges. We found the burden of...
