Covalent organic frameworks (COFs) refer to all-organic crystalline, porous polymers that show promise for a variety of applications, including controlled drug delivery. However, research on COFs ...

3D covalent organic frameworks with zyg topology for photocatalytic synthesis of hydrogen peroxide. Story by Science X staff • 5mo. A research team proposed a new synthetic strategy of COFs ...

COF-505 is the first 3D covalent organic framework to be made by weaving together helical organic threads, a fabrication technique that yields significant advantages in structural flexibility, ...

In a step forward for soft robotics and biomedical devices, Rice University engineers have uncovered a powerful new way to boost the strength and durability of silicone-based soft devices without ...

Flexible bonds are great for multiple covalent bonds, ... you’re only limited by your imagination and how long you are willing to spend printing atoms and bonds. [3D Printy] ...

These novel materials can change, fix, and retain their shape reversibly by using magnetic fields and ultraviolet light.

A shorter hydrogen bond, for instance, indicates stronger hydrogen bonding and a relatively weaker covalent bond. This was reflected, as expected, in lower spectroscopic frequencies for the H–F ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two.

Drugs that make covalent bonds to biological targets have been around for more than a century. Aspirin. Anti-inflammatory drug. First sold in 1899. Penicillin V. Antibiotic. Discovered in 1928.
