Mechanical Properties of Alumina-Mullite Whisker Composites
Composite alumina ceramics with a mullite whisker content of up to 30vol% were fabricated by hot-pressing at 1400 to 1600°C under 30MPa for 30min. The bending strength, hardness, elastic modulus and fracture toughness of the hot-pressed bodies were investigated. Considerably dense alumina-mullite whisker composite ceramics were obtained by sintering at

Impact of Different Types of Dust on Solar Glass Transmittance and PV Module Performance
This study characterizes the soiling losses between four natural dusts. It identifies significant differences in soiling losses, showing that a particular dust from Thailand has a 12.8% higher transmittance loss slope. In addition, measured slopes of Isc losses are consistently lower than calculated values, with an average discrepancy of 16.6%.

Novel MMT‐SiOC ceramic nanocomposites are prepared. At 900°C and 1200°C, growth and refinement of a crystalline α‐SiO2 phase on the MMT nanoflakes led to 2 to 5 nm pores upon etching. The size of the SiO2 domains appeared to be diffusion‐limited by turbostratic C phases in the SiOC matrix.
