An inexpensive one-pot route to self-healing hydrogels with pH-tunable modulus is presented. Hydrogels were formed by reacting tannic acid, trivalent metal ions and polyallylamine. Below pH 8 the hydrogels were supramolecular while above, covalent cross-linking strengthened the hydrogels. From concentrated mixtures, threads were spun, acting as water sensitive mechanical locks.
Tb-Fe-B alloys have been melt spun and data obtained for the room temperature magnetisation and magnetostriction as functions of applied field and composition. Small additions of La (w 5 at. %) leave the magnetisation unchanged but substantially reduce the magnetostriction. Results are compared with sputtered binary metallic Tb/Fe alloys.
The superior mechanical properties of carbon nanotubes (CNTs) mean they have been regarded as a new material with the potential to revolutionize and enable many advanced technologies. CNTs have extremely high tensile strength ( 150 GPa), high modulus ( 1 TPa), large aspect ratio, low density, good chemical and environmental stability, and high thermal and electrical conductivity. These superior...
