This research developed new nanostructured Al–Fe3O4 composites via accumulative roll bonding (ARB). X-ray diffraction (XRD) analysis and field emission scanning electron microscopy were conducted to examine microstructural characteristics and particle distribution in the nanocomposites. Hardness and tensile strength tests were employed to examine their mechanical propertie...

I investigate band and Mott insulating states in a two-band Hubbard model, with the aim of understanding the differences between the idealised oneorbital model and the more realistic multi-band case. Using a projection ansatz I show that additional orbitals suppress the metal-insulator transition, leading to a critical coupling of approximately eight times the bare band-width. I also demonstrat...

The anti-triplet charmed baryon decays with the light scalar mesons are rarely measured, whereas recent observation of Cabibbo-favored Λc+→Ληπ+ decay hints a possible Λc+→Λa0(980)+,a0(980)+→ηπ+ process. We hence study Λc+→Λa0(980)+ decay. Particularly, it is found that final state interaction can give significant contribution, where Σ+(1385) and η in Λc+→Σ+(1385)η by exchanging charged pion tra...

This paper is concerned with a new type of deployable structures that can be rolled up like a tape measure but, unlike a tape measure, are stable in two different configurations. The key to the behaviour of these structures is a particular type of composite construction based on an anti-symmetric lay-up of glass fibres in a polypropylene matrix. The paper presents a finite element analysis usin...

and life history depending on environmental conditions. These environmental responses are both trait and resource specific, and represent evolved characteristics that vary among genotypes, populations and species. The past 15 years have seen an explosion of interest in this capacity of a given genotype to express different phenotypes in different environments, a phenomenon known as phenotypic p...
