TEAMER program has selected seven projects to receive technical support for testing marine energy technologies as part of its seventh call for applications.

This paper reviews the high-temperature behavior of a selected range of silicones used for sealing and bonding in construction.

In a paper recently released in the open-access journal Energies, researchers used national institute of standards and technology (NIST) real gas simulation models and the modified k-? turbulence for the numerical simulation of rapid filling of high-pressure hydrogen storage cylinders.

This paper compares the microstructure and mechanical evolution in a high-strength quenched and micro-alloyed steel during the austenitising bending process. Simulation results indicated a new finding that the stress neutral layer (SNL) tends to move to the tension zone during straining. The hardness gradient detected from the centre to compression/tension zones was resulted from comprehensive factors: First of all, the location of SNL revealed a prominent impact on strength. Second, the disloca...

This paper focuses on the experimental study of shear testing of 15.2 mm, 25 t capacity seven wire cables at zero, 30° and 45° angles using two different shear testing facilities at the University of Wollongong (UOW) and the University of Southern Queensland (USQ) in Toowoomba. A circular double-shear rig MK-IV was used for testing cable perpendicular to the sheared joint faces (zero angle of orientation), while testing the cable at 30° and 45° was carried out using a larger-size rectangular...

Pretension is the pre-added axial tensile force on fully grouted bolt systems, which include rock bolts and cable bolts. Although a series of studies via lab testing and analytical modelling proved the importance of pretension in cable bolts, there is no systematic analysis to guide the optimal pretension values to be applied on cable bolts in different engineering geological conditions. Complicated geological conditions, such as anisotropic in-situ stress, bedding plane detachment and country r...

Compared to Si-based nanostructures, (GaAs)-based solar cell nanostructures have been found to have higher absorption properties.

It has been numerically demonstrated that the turbulence above the boundary is important to tropical cyclone intensification and rapid intensification, but the three-dimensional structures of the sub-grid-scale (SGS) eddy have not been revealed due to the lack of observational data. In this study, two numerical simulations of Super Typhoon Rammasun (2014) were conducted with the Advanced Weather Research and Forecast (WRF) model by incorporating the large-eddy simulation (LES) technique, in whic...

(2019) Wang, Morgan. Journal of Geophysical Research: Solid Earth. The large magnitude of the 2011 Mw 9.0 Tohoku-Oki earthquake, which occurred off the east coast of Japan, was not expected or predicted by any previous studies. One surprising observation was the sudden change in stress state; loc...

Researchers develop new tool to simulate the impact of SARS-CoV-2 strains and vaccines The MOMAT research group from Universidad Complutense de Madrid has worked with Universidad de Almería, to develop a mathematical model that simulates the impact of SARS-CoV-2 strains and vaccines together, combined with many other biological and social processes in the propagation of COVID-19. The tool can be downloaded without restriction and free of charge and applied to any territory. It forms part of th...
