Effect of a Graded Layer on the Plastic Dissipation During Mixed-Mode Fatigue Crack Growth on Ductile Bimaterial Interfaces
… Since then, this theory has been extended to layered material systems that typically include mixed-mode loading and elastic/plastic mismatch. Previous research by the author first extended this theory to include a graded layer (i.e., no step change in material properties across the crack …

Accelerated Testing of Separation Layers for Open-Graded Drainage Layers
… developed to evaluate performance of separation layers used between open-graded bases and lime stabilized subgrades. Significantly of concern was assessing separation layer performance in regard to the degree of pumping into the open-graded base and the magnitude of deformations occurring during …

The natural interface between bone and tendon : SEM observations of the enthesis in an ovine model
… The micrographs revealed a cartilaginous layer, 100 to 400 [mu]m thick apposing bone, that contained cells varying in size and shape as a function of their location in this cartilaginous layer. Further investigation is required to conclude whether these cells are undergoing further …

Characterization of novel sb-nanostructures by transmission electron microscopy techniques for high efficient solar cells
… to different QD configurations of the first layer. Second, the addition of Sb inhibits the formation of agglomerations promoting VAQD columns. Each column consists of a sequence of alternating pyramidal QDs of In(Ga)As and GaAsSb blocks surrounded the QD apex like a collar. Thirdly, the use …

Preparation and characterization of AlGaN structures for UVA LEDs
… AlGaN is routinely used as an electron-blocking layer in visible and UV LEDs, does it act as such and how effective is it? b) How to achieve a low dislocation density template for UV (310-350 nm) LEDs where no native substrates for homoepitaxy are available for low-mid Al content AlGaN? …
