Potential and challenges of computing with molecular materials
Molecular materials for computing progress intensively but the performance and reliability still lag behind. Here the authors assess the current state of computing with molecular-based materials and describe two issues as the basis of a new computing technology: continued exploration of molecular electronic properties and process development for on-chip integration.
An unprecedented feat: Printing 3D photonic crystals that completely block light
Photonic crystals are materials with repeating internal structures that interact with light in unique ways. We can find natural examples in opals and the vibrant colored shells of some insects. Even though these crystals are made of transparent materials, they exhibit a “photonic bandgap” that blocks light at certain wavelengths and directions.
New method improves understanding of light-wave propagation in anisotropic materials
Understanding how light travels through various materials is essential for many fields, from medical imaging to manufacturing. However, due to their structure, materials often show directional differences in how they scatter light, known as anisotropy. This complexity has traditionally made it difficult to accurately measure and model their optical properties. Recently, researchers have developed a new technique that could transform how we study these materials.
Human bone-inspired cement is 5 times tougher than standard concrete
Getting tips from the design of the human body.
Scientists create bone-inspired cement, over five times stronger than concrete.
Researchers at the University of Princeton have developed a cement paste that is 5.6 times stronger than cement, mortar, and other conventional cement-based construction materials.
The paste features a tubular architecture inspired by the structure of human cortical bone, which forms the outer layer of the femur (thigh bone).
“Cement paste deployed with a tube-like architecture can significantly increase resistance to crack propagation and improve the ability to deform without sudden failure,” according to the researchers.
