Tissue engineering: construction of a multicellular 3D scaffold for the delivery of layered cell sheets. [PDF]

, 2014
Many tissues, such as the adult human hearts, are unable to adequately regenerate after damage.(2,3) Strategies in tissue engineering propose innovations to assist the body in recovery and repair. For example, TE approaches may be able to attenuate heart

Thermoresponsive poly(N-vinylcaprolactam) as stationary phase for aqueous and green liquid chromatography [PDF]

, 2010
Poly(N-vinylcaprolactam) (PVCL) connected to aminopropyl silica is a new stationary phase for temperature responsive liquid chromatography (TR-LC). PVCL shows a transition from hydrophilic to hydrophobic interaction between 30 and 40 degrees C.

Swelling Deswelling Behavior of PS‐PNIPAAM Copolymer Particles and PNIPAAM Brushes Grafted from Polystyrene Particles & Monoliths

Macromolecular Materials and Engineering, 2008
AbstractTwo sets of emulsion particles have been synthesized. In the first set, surfactant free emulsion was used to directly synthesize PS‐PNIPAAM copolymer particles. In the second set, polystyrene particles with an ATRP initiator shell were first synthesized and subsequently grafted with PNIPAAM brushes.

Core-sheath nanofibers as drug delivery system for thermoresponsive controlled release [PDF]

, 2017
In this work, a smart drug delivery system of core–sheath nanofiber is reported. The core-sheath nanofibers were prepared with thermoresponsive poly-(N-isopropylacrylamide) (PNIPAAm) (as core) and hydrophobic ethylcellulose (EC) (as sheath) by coaxial ...

Anisotropic, Strong, and Thermally Insulating 3D‐Printed Nanocellulose–PNIPAAM Aerogels

Small Structures, 2023
Cellulose is a promising candidate for the fabrication of superinsulating materials, which would be of great interest for thermal management applications as well as for the scientific community. Until now, the production of strong cellulose‐based aerogels has been dominated by traditional manufacturing processes, which have limited the possibilities to
