QUT researchers have used experimental x-ray techniques at the Australian Synchrotron to gain fundamental insights into how gypsum dehydrates under pressure and the processes that create earthquakes.
In the study published in the Nature Research journal
Communications Materials, QUT researchers Dr Christoph Schrank, Dr Oliver Gaede, from the School of Earth and Atmospheric Sciences, and Master of Science graduate Katherine Gioseffi teamed up with the Australian Synchrotron and colleagues from the University of New South Wales and the University of Warsaw to study how gypsum dehydrates much faster under pressure.

Nottingham University and the National Physical Laboratory have found that stabiliser residue in metal nanoparticle inks inhibits conductivity in 3D-printed electronics.

Inks containing metal nanoparticles (MNP) are among the most commonly-used conducive materials for 3D-printed electronics. Ink-jetting layers of MNP materials allow for design flexibility, rapid processing and 3D printing of devices such as sensors, solar panels, LED displays, transistors and smart textiles.

Inks containing metal nanoparticles are among the most commonly-used conductive materials for printed electronics. Ink-jetting layers of MNP materials allows for unpreceded design flexibility, rapid processing and 3D printing of functional electronic devices such as sensors, solar panels, LED displays, transistors and smart textiles.
Inkjet 3D printing of metals typically form a solid printed object via a two-step process: solvent evaporation upon printing (pinning) and subsequent low-temperature consolidation of nanoparticles (sintering). The low temperature is important as in many applications the nanoparticles are co-printed with other functional/structural organic materials that are sensitive to h

In 2018, Habitat launched “Global Impact 2025” (GI25). The initiative seeks to transform Habitat’s global operations to align with the ambition of its strategic plan, “to materially reduce the housing deficit.” The past three years have established a foundation for that growth: introducing the ministry’s first international theory of change; building the capacity for new revenue streams; and co-creating new models for more integrated operations across the Habitat network. As we move into the next phase for GI25, we are accelerating the transformation of our supporting teams.
Purpose of Consultancy
A critical component in the overall transformation has been the effort to establish a new operating model capable of realizing greater impact in Sub-Saharan Africa (SSA). Habitat has operated within the SSA context for its entire history, beginning in Zaire in 1973 even before the international arm of our network was formed. Since that time, Habitat has helped fam
