Stretching‐Orientation Reinforced Double Network Solvent‐Free Eutectic Gels for Ultrarobust, Flexible Human‐Machine Interaction Devices

Advanced Functional Materials, EarlyView.
This work develops an ultrarobust, flexible, and solvent‐free eutectic gel featuring stretch‐induced orientation. Overcoming hydrogel limitations, the gel achieves record toughness (133.86 MJ m−3) while integrating strain/temperature/capacitive sensing.

Photostabilizing Efficiency of PVC in the Presence of Schiff Bases as Photostabilizers

Molecules, 2015
The photostabilization of polyvinyl chloride (PVC) films by Schiff bases was investigated. Polyvinyl chloride films containing 0.5 wt % Schiff bases were produced using the same casting method as that used for additive-free PVC films from tetrahydrofuran

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

Advanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

Polyphosphates as Inhibitors for Poly(vinyl Chloride) Photodegradation

Molecules, 2017
Three polyphosphates were used as inhibitors for poly(vinyl chloride) (PVC) photodegradation. The polyphosphates were added to PVC at a concentration of 0.5% by weight. The PVC films (40 µm thickness) were irradiated at room temperature with ultraviolet (

Graft Reaction of Furfural with Polyvinyl Chloride and Its Effect on Thermal Stability of Polyvinyl Chloride

Organics
A graft reaction of polyvinyl chloride (PVC) with furfural was conducted in a tetrahydrofuran solution. The resulting graft structure (FF-g-PVC) was characterized using UV spectroscopy, photoluminescence (PL), Fourier Transform Infrared (FTIR ...

High‐Throughput Encapsulation of Stem Cells: Characterizing Dynamic Culture Variability With a Millifluidic Approach

Advanced Healthcare Materials, EarlyView.
A high throughput millifluidic encapsulation platform is engineered and standardized. The system's output allows the monitoring of cell expansion in strong dynamic conditions. High polymer crosslinking leads to higher cell proliferation and lower cell growth on microgel's surface.

Investigation on the Influence of Protein Corona and Platelet Adhesion on Storage Bag Surface on the Platelet Storage Lesion

Advanced Healthcare Materials, EarlyView.
Platelet quality deteriorates during storage due to protein and platelet adhesion to current bag materials. Here, polymer coatings are identified that reduce adhesion and translated them to mini‐storage bags. Platelet quality are not impacted, despite significantly reducing adhesion.
