Polymer surfactants refer to substances whose molecular weight reaches a certain level (ie, the molecular weight is generally 103 to 106) and has a certain surface activity [1-10]. From the structure can be divided into block copolymers, graft copolymers and so on. If polymer surfactants are classif...

With people's attention to low-carbon economy and global climate, the rational use of coal energy and energy-saving and emission-reduction measures are becoming more and more important. It will be very necessary and timely to introduce relevant information.

Polyethylene glycol and its derivatives are polyether compounds with many applications, from industrial manufacturing to medicine. Researches on PEG and its derivatives become a hot topic in decades, especially in the medical and biological fields.

Three dimensional (3D) bioprinting has emerged as a promising new approach for fabricating complex biological constructs in the field of tissue engineering and regenerative medicine. What is 3D Bioprinting? What are bio-ink materials for it? How does it work and what are the applications of it?
