Scientists turn dents into smart bumps

Due to a phenomenon called the shape memory effect (SME), certain "memory metals" can be distorted and then brought back to their original shape by a simple temperature change. While a one-way memory effect has inspired applications ...

Protein-Nanoparticle Material Mimics Human Brain Tissue

A composite material consisting of a horse protein and metallic nanoparticles displays magnetic properties very similar to those of human brain tissue, scientists have found. The work, published in the June 20 online edition ...

Negative piezoelectric effect is not so rare after all

(Phys.org)—The piezoelectric effect, which causes a material to expand along the direction of an applied electric field, is common in many materials and used in a variety of technologies, from medical ultrasound to vibration-powered ...
