Advanced Science, EarlyView.Dual priming with minocycline and photodynamic priming reprograms the pancreatic tumor microenvironment to overcome chemoresistance. By suppressing DNA repair enzyme Tdp1, inducing photooxidative damage, and enhancing irinotecan delivery via light‐activated nanoencapsulation, this strategy remodels the tumor microenvironment and drives immune ...

Advanced Science, EarlyView.Dynamic decellularized hydrogels are prepared using bovine decellularized small intestine submucosa (SIS) norbornene (dSIS‐NB). Bovine dSIS contained significant amounts of disulfide‐rich fibrillin‐I, enabling ‘self‐clickable’ thiol‐norbornene gelation and spatiotemporal tuning of hydrogel physicochemical properties.

Reactive Extrusion for Thermoplastic Starch-Polymer Blends
, 2014 This chapter briefly reviews reactive extrusion developments for thermoplastic starch polymers. Then, a case study for thermoplastic starch polymer/biopolyester nanocomposite blend will be examined. In this example, maleic anhydride and dicumyl peroxide were used as cross-linking agent and initiator, respectively, for blending starch and a ...

Reactive Extrusion of Styrene Polymers
International Polymer Processing, 1993Abstract Reactive extrusion is the term used to denote a plastics processing method in which an extruder is used as a reactor for the continuous synthesis and modification of polymers. This paper describes the manufacture of polystyrene and styreneisoprene copolymers by a reactive extrusion process: anionic “living” s-butyl lithium ...

Esterification in reactive extrusion
Polymer Engineering & Science, 1995AbstractA condensation type reaction has been studied for reactive extrusion in a twin‐screw extruder. The esterification reaction is to graft a nonylphenyl‐ethoxylate (NP8) onto a pre‐maleated ethylene‐propylene (EPRMA). The kinetics were initially characterized in the static mixture using a thermally controlled call in a FTIR spectrometer. These were

Reactive Extrusion of SAN/EPDM Blends
International Polymer Processing, 2004Abstract The blending of styrene-acrylonitrile copolymer (SAN) and three different types of ethylene-propylene-diene terpolymer (EPDM) by reactive extrusion was studied and the free radical initiators: 2,5-dimethyl-2,5-di-(t-butylperoxy)hexane (Luperco 101 XL), 2,5-dimethyl-2,5-di-(t-butylperoxy)hexyne-3 (Luperco 130 XL), α,α′-di(t ...

Role of Mixing and Rheology in Reactive Extrusion
Industrial & Engineering Chemistry Research, 1994To understand the performance of multicomponent reactions in extruders, the mixing mechanism in the extruder has to be understood. Viscosity and quantity differences between the components fed to the extruder considerably influence this mixing process. The extent of their influence on the mixing and therewith the reaction process was investigated with ...
