Porous brittle solids have the ability to collapse and fail even under compressive stresses. In fracture mechanics, this singular behavior, often referred to as anticrack, demands for appropriate continuum models to predict the catastrophic failure. To ide ...
New types of metamaterials and architectured material require metallic materials with precise
structural design in the microscale. However, additivemanufacturing of metallic structures in
themicroscale has proven difficult, as the demand for the material q ...
To mitigate the rising level of CO2, biological method of CO2 sequestration is one of the effective methods. Chemolithotrophic microbes are able to fix atmospheric CO2 and precipitated polymorphic minerals like calcite, vaterite and aragonite. Based on thi ...
Cemented carbides are hard materials used for the fabrication of cutting tools. They consist of hard micron or sub-micron carbide grains held together in a matrix of a tough metallic binder such as cobalt. The understanding and control of cobalt characteri ...
A multi-step process is developed to create a nacre-like ceramic/metal composite. First, a slurry of Ni-coated alumina platelets and NiO nano-particles is directionally freeze-cast and the ice is sublimed, creating a foam with aligned lamellar walls contai ...
Thermal scanning probe lithography (t-SPL) is an advanced lithography technique in
which a heated atomic force microscope tip locally modifies a sample material. Due to
the nanometer-sized tip apex diameter, t-SPL enables patterning of sub-10 nm structures ...
