New competition for MOFs: Scientists make stronger COFs

more »
Hollow molecular structures known as COFs suffer from an inherent problem: It's difficult to keep a network of COFs connected in harsh chemical environments. Now, a team has used a chemical process discovered decades ago to make the linkages between COFs much more sturdy, and to give the COFs new characteristics that could expand their applications.

Microscale superlubricity could pave way for future improved electromechanical devices

more »
A new study finds that robust superlubricity can be achieved using graphite and hexagonal boron nitride, which exhibit ultra-low friction and wear. This is an important milestone for future technological applications in the space, automotive, electronics and medical industries.

Sunscreen for dancing molecules

more »
This study is the first to use heavy water (D2O) - a form of water that contains deuterium (D) instead of hydrogen - in the field of transmission electron microscopy (TEM). This approach significantly delays sample damage, which is one of the major impediments for broader application of liquid-phase TEM to fragile biological samples.
