Researchers made a series of polymer gels with breakable bonds incorporated into different parts of the structure, and tested whether the properties changed after the gel was degraded and reformed.
The researchers hope this model system can be applied to other types of polymers, including adhesives, sealants and elastomers.
The Bangladesh Forest Research Institute (BFRI) has introduced three groundbreaking rubber varieties—RM 001, RM 002, and RM 003—to address persistent challenges in the country’s rubber industry.
With locally cultivated rubber trees experiencing low latex yields, these varieties have the potential to transform commercial rubber farming in Bangladesh.
The genesis of this breakthrough lies in BFRI’s long-term mission to revive the dormant rubber industry. Cloned from high-yielding rubber trees in Malaysia, the newly developed varieties thrive in two soil types—sand and loam—and require minimal fertilization.

Read MoreThe snow chain-integrated tire technology consists of a wheel and tire assembly that feature radial grooves at regular intervals, like a pizza, with modules made of shape memory alloy inserted into these channels.
This technology takes advantage of the shape memory alloy’s ability to return to its original shape when an electric current is applied. During normal driving, the shape memory alloy located inside the wheel is compressed into the shape of the letter ‘L’ and does not contact the road surface. When the driver activates the function, an electric current is applied, causing the shape memory alloy to revert to its original profile; the material forms a ‘J’ shape, pushing the module out of the tire to make contact with the surface, improving grip, stability and safety on snowy roads.
