A systematic investigation has been carried out to determine how the shape of X-ray line profiles from stretched aluminium foils is influenced by increasing levels of induced residual strain. Macroscopic residual strains from 4% to values close to the breaking point (220%) were induced by stretching annealed foils beyond the yield point into the plastic deformation region and then releasing the...

The plasma arc melting of mixtures oxygen-mayenite and solid-reductants (aluminum graphite) enables the scalable synthesis mayenite-based electrides with treatment times below one minute.

Monolithic ceramics have been fabricated from coated green fibers to create fibrous microstructures. The fibrous monoliths consist of high aspect ratio polycrystalline regions (cells) of a primary phase separated by thin secondphase regions (cell boundaries) designed to improve fracture resistance. The cells are the remnants of the green fiber which consists of ceramic powder and a polymer bind...

The propagation of leaky Lamb waves in a plate consisting of a general balanced symmetric composite material is considered. The problem has been examined both analytically as well as experimentally. An exact solution for the dispersion equation was obtained. Numerical results for complex‐valued wavenumber were obtained for an isotropic material (aluminum) and a (0/903)s graphite/epoxy laminate....

For many years, new techniques have been developed to overcome the problems involved with the generation and detection of ultrasound in materials at high temperature [1,2]. A non-contacting technique is described using lasers to generate and detect ultrasound and which can be used to study the variation in acoustic velocity as a function of temperature. Results are presented for the change in l...

Aluminum–metal batteries show great potential as next-generation energy storage due to their abundant resources and intrinsic safety. However, the crucial limitations of metallic Al anodes, such dendrite corrosion problems in conventional aluminum–metal batteries, remain challenging elusive. Here, we report a novel electrodeposition strategy prepare an optimized 3D anode on carbon cloth with un...

The purpose of the present study was to investigate the in vitro and in vivo effects of aluminum sulfate on delta-aminolevulinic acid dehydratase (ALA-D) activity from the brain, liver and kidney of adult mice (Swiss albine). In vitro experiments showed that the aluminum sulfate concentration needed to inhibit the enzyme activity was 1.0-5.0 mM (N = 3) in brain, 4.0-5.0 mM (N = 3) in liver and ...
