Actuating and Sensing Composites of Liquid Crystal Elastomers and Poly(ionic liquid)s

Advanced Functional Materials, EarlyView.
Ionic conductive, mechanically tough, flexible, and stretchable filaments of a composite material comprising a liquid crystal elastomer and a poly(ionic liquid) are produced through 3D printing, which exhibit large actuation strain under stimulation and electrical resistance variation in response to deformation or environmental condition changes.

Simple Bedside Predictors of Survival after Percutaneous Gastrostomy Tube Insertion

Canadian Journal of Gastroenterology and Hepatology, 2019
Background. Percutaneous endoscopic gastrostomy (PEG) tube insertion is an increasingly used minimally invasive method for long-term enteral feeding. Identification of simple predictors for short-term mortality (up to one month) after PEG insertion is of

Polymer Infiltration Into SURMOF Channels Enables Hydrophobic and Solid‐Like Slippery Functional Thin Films

Advanced Functional Materials, EarlyView.
We report a polymer‐chain insertion strategy to fabricate pore‐threaded MOF thin films with precisely tuned surface chemistry and wettability. Grafting n‐alkane chains into the pillared layer Cu2(bdc)2(dabco) MOF thin film's vertical nanochannels enhances water stability, and induces hydrophobicity and lubricant‐free, solid‐like slippery behavior ...

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).

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 ...
