Scientists develop earthquake-proof concrete

Researchers from University of British Columbia (UBC) in Canada have developed earthquake-proof fibre-reinforced concrete that can dramatically enhance the earthquake resistance of seismically vulnerable structures.

Key Facts

The cement material is engineered at molecular scale to be strong, malleable, and ductile similar to steel. It is capable of dramatically enhancing earthquake resistance of seismically vulnerable structure when applied as a thin coating on surfaces.

The material is made of eco-friendly ductile cementitious composite (EDCC) which combines cement with polymer-based fibres, flyash and other industrial additives, making it highly sustainable. It was subjected earthquake intensities as high as magnitude 9.09.1 earthquake during simulations. In India, EDCC will be retrofitted in school at Roorkee in Uttarakhand, a highly seismic area for research purpose.


Scientists develop injectable tissue bandage to repair hearts

Scientists from the University of Toronto, Canada have developed an injectable tissue bandage dubbed as AngioChip, smaller than a postage stamp that can repair damaged hearts.

The AngioChip is a tiny patch of heart tissue with its own blood vessels and heart cells beating with a regular rhythm. It is made out of the biocompatible, biodegradable polymer.

Key Facts

Repairing heart tissue destroyed by a heart attack or medical condition with regenerative cells usually requires invasive open-heart surgery which usually poses more risks than potential benefits. The newly developed technique lets researchers to inject a repair patch (AngioChip) using a small needle, without the need to open up the chest cavity. Researchers by injecting the patch into rat hearts have shown that it can improve cardiac function after a heart attack.
