electroadhesion of rough surfaces, with application to touch screen technology
Just submitted a paper on electroadhesion of rough surfaces, greatly simplifying the recent theory of the great Bo Persson , with hot application to touch screens : see here.
Comments welcome.
The remarkable mechanical properties of crumpled materials
Mechanics of crumpled materials
Crumpled materials exhibit unusual and as yet unexpained mechanical properties. Through the surprisingly complex morphologies of facets and ridges formed in the crumpling of paper into a ball or densser materials, very high strength to weight ratios can emerge.

The effects of pore geometry on fracture mechanics is studied by considering notches of various types with a uniform crack growth. This work, published in Engineering Fracture mechanics, sheds light on the role of stress concentrators in the toughness of porous materials.
Additive manufacturing of ceramics from preceramic polymers
Additive manufacturing of ceramics from preceramic polymers
Following extensive research by our outstanding doctoral candidate here, Dr. Wang, a publication in the journal Additive Manufacturing is now in press.
Improved oxidation resistance of high emissivity coatings for reusable space systems
Here novel disilicides were explored for use in heat shields.
WSi2 and MoSi2 were applied as coatings on an insulating zirconia substrate.
The high emissivity of these compounds and their mixtures, makes them very attractive for use in spacecraft.
Compressive performance of MAX phase composites
Compressive performance and crack propagation in MAX phase composites
Here micro CT was used to reveal the structure performance relationships in metal/ceramic composites based on Ti2AlC / Al alloy combinations.
The results show the promise of infiltrated max phase materials in the production of high performance composites.
Theoretical insights into the hydrophobicity of low index CeO2 surfaces
