Australian scientists have developed a breakthrough low-cost, lightweight, concrete technology that is set to lower costs and speed up construction projects from residential homes to high-rise buildings.
HySSIL (High-Strength, Structural, Insulative, Lightweight) panels are manufactured using a new low energy, process developed by CSIRO Novel Materials & Processes. Dr Swee Liang Mak, who leads the HySSIL development team at CSIRO says, ’HySSIL is a revolutionary aerated cementitious (cement-based) product that is as strong as normal concrete but is only half as heavy. It provides up to five times the thermal insulation of concrete and is also impact and fire resistant’. ’HySSIL wall panels are also expected to offer significant cost advantages over existing products’, says Dr Mak.
’Significant savings are achieved because CSIRO HySSIL technology uses readily available raw materials in smaller quantities and the-low cost and low-energy technology developed by CSIRO. ’Unlike certain processes used to manufacture aerated products, HySSIL production does not require expensive autoclaves (curing equipment)’. Dr Mak says, ’This means there are significant savings on the cost of start-up manufacturing plant for HySSIL’.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
