In this work, microwave heating approach was introduced into the preparation process of zirconia materials to overcome tricky technical defects during traditional electric arc furnace method. Magnesia-partially stabilised (MgO-PSZ) with enhanced stability and a uniform microstructure prepared via ZrO2 sample manufactured by The effects on phase properties, microstructure, surface morphology MgO...
Refractory Y-α-SiAlON with elongated grain morphology was obtained by utilizing La2O3 as a densification aid, which resulted in excellent room-temperature and high-temperature strength. Room-temperature strength of 1000 MPa was achieved when La2O3 was augmented by adding Y2O3 or removing AlN. With only La2O3, a temperature-independent strength of 800–950 MPa was maintained up to 1100°C, then gr...
in this study the performance of clay nano-particles on the soil reinforced with polypropylene fibers (pp-fiber) has been investigated. also a series of investigations concerning the effect of random orientation of fibers on the engineering behaviour of soil were conducted. soil mixtures were modified with varying percentages of nanoclay and fibers. unconfined compressive strength (ucs), compac...
Hybrid lead halide perovskites have emerged as high-performance photovoltaic materials with their extraordinary optoelectronic properties. In particular, the remarkable device efficiency is strongly influenced by the perovskite crystallinity and the film morphology. Here, we investigate the perovskites crystallisation kinetics and growth mechanism in real time from liquid precursor continually ...
CrSiN films with various Si contents were deposited by reactive magnetron sputtering using the codeposition of Cr and Si targets in the presence of the reactive gas mixture. Comparative studies on microstructure and mechanical properties between CrN and CrSiN films with various Si contents were carried out. The structure of the CrSiN filmswas found to change from crystalline to amorphous struct...
One of the most efficient approaches to design the properties of a material is through the control of its phase transformations and microstructure evolution. The processes involved in a phase transformation are inherently multiscale. It starts with the nucleation of nanoscale nuclei of new phase particles, followed by growth and particle impingement or coarsening. In our recent works, we have d...
