Injuries and degenerative diseases to load-bearing soft tissues are extremely common in hospital clinics and involve all ages of the population. Tissue engineering provides a major focus for developments within this area due to the relative failure of graft and prosthetic-based strategies. On implantation, such system…

The size-dependent mechanical response of a simple model microstructure is investigated using continuum dislocation-based, Cosserat and strain-gradient models of crystal plasticity. The governing equations and closed-form analytical solutions for plastic slip and lattice rotation are directly compared. The microstruct…

Diffusion coefficient of 95Nb in α-iron has been determined in the temperature range between 823 and 1163 K by use of a serial sputter-microsectioning technique. The diffusion coefficient of niobium is about two times as large as the self-diffusion coefficient in α-iron. The temperature dependence of the diffusion coe…

This study focuses on the changes in the supermolecular structure of cellulose of natural fibres after the mercerisation process by sodium hydroxide. This process is the first step in the modification of the natural fibresi surface which is performed in order to remove waxes and fats, in consequence of which the fibre…

We investigated the creep strength of fine‐grained aggregates of single‐phase anorthite and diopside at temperatures ranging from 1253 to 1553 K at flow stress between 5 and 250 MPa and at 0.1 MPa pressure. Powders of crushed natural, iron‐bearing diopside and of pure anorthite and diopside glasses were hot pressed at…

Mesoporous materials containing bridged cyclam moieties inside the framework were prepared by using a neutral templating route. Quantitative formation of bridged CuII-cyclam complexes was obtained by the direct incorporation of CuCl2 inside the hybrid material, showing thus the complete accessibility of cyclam moietie…

Hydrogen peroxide is generally considered to be a green oxidant, as it is relatively non-toxic and breaks down in the environment to non-toxic by-products. However, the current method for production, the sequential hydrogenation and oxidation of an alkyl anthraquinone, is capital-intensive, produces significant volume…

The temperature dependent thermoelectric power (TEP) of boron- and nitrogen-doped multiwalled carbon nanotube mats has been measured showing that such dopants can be used to modify the majority conduction from p-type to n-type. The TEP of boron-doped nanotubes is positive, indicating hole-like carriers. In contrast, t…

Neutral aluminum oxide clusters are produced in a molecular beam by laser vaporization in a pulsed-nozzle cluster source. These clusters are ionized via (multi-) photon absorption from either an ultraviolet excimer laser or from a far-infrared free electron laser. Ultraviolet (multi-) photon ionization produces sparse…
