Quality by design & failure mode and effects analysis applied to the eco-friendly synthesis of PCL-co-PEG copolymers

Discover Materials
Polycaprolactone-co-polyethylene glycol (PCL/PEG) is a biodegradable and biocompatible copolymer that combines the hydrophobicity of polycaprolactone (PCL) with the hydrophilicity of polyethylene glycol (PEG).

Fabrication of Pliable Biodegradable Polymer foams to Engineer Soft Tissues

Cell Transplantation, 1996
We have fabricated pliable, porous, biodegradable scaffolds with poly(lactic-co-glycolic acid) (PLGA) and poly(ethylene glycol) (PEG) blends using a solvent-casting and particulate-leaching technique.

Electroactive Liquid Crystal Elastomers as Soft Actuators

Advanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Generating Cell Surface Nucleated Hydrogels with an Artificial Membrane‐Binding Transglutaminase

Advanced Functional Materials, EarlyView.
Cell‐based therapies require advanced strategies to enhance cell delivery and bioactivity. Cell membrane engineering offers an avenue to impart new functions to delivered cells to boost their viability and function. Here, an artificial membrane‐binding transglutaminase is generated and biophysically characterized.

Improving sensitive-reactant efficiency in site-specific PEGylation via semi-batch processing: simulation-based evaluation under throughput constraints

Chemical Engineering Journal Advances
Semi-batch reactors are preferred for highly exothermic reactions, consecutive/parallel reaction networks, and sensitive reactants. For instance, site-specific PEGylation can benefit from semi-batch reactions through the feeding of sensitive, activated ...

A matched comparison of revision rates of cemented Oxford Unicompartmental Knee Replacements with Single and Twin Peg femoral components, based on data from the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man

Acta Orthopaedica, 2020
Background and purpose — Registries report high revision rates after unicompartmental knee replacement (UKR) due, in part, to aseptic loosing. In an attempt to improve Oxford UKR femoral component fixation a new design was introduced with a Twin rather ...

Endothelial Cells Angiogenesis in Sulfated Glycosaminoglycan (GAG) Hydrogels Enhanced by Bioactive Glass‐Released Ions

Advanced Functional Materials, EarlyView.
A mechanically tunable hydrogel composed of gelatin, chondroitin sulfate and laminin promotes angiogenesis in vitro without the supplement of growth factors. Endothelial cells morphogenesis was further enhanced by medium conditioned with bioactive glass 58S‐released ions (Ca and Si), thus offering a promising strategy to vascularize 3D tissue ...
