Scalable manufacturing of microphysiological systems to extend the production volume

Current Directions in Biomedical Engineering
Microphysiological systems (MPS) have emerged as a valuable tool in preclinical drug testing. These systems are capable of simulating in vivo conditions and physiological functions within an ex vivo tissue culture setting, resulting in improved accuracy ...

Manufacturing of unidirectional stitched glass fabric reinforced polyamide 6 by thermoplastic resin transfer moulding

Materials & Design, 2020
This study aims to address barriers which remain to adoption of reactive thermoplastic resin transfer moulding in terms of knowledge and equipment. Glass fibre reinforced polyamide 6 composites with ~52% fibre volume fraction and ~1% voids were produced ...

A technique for the measurement of reinforcement fibre tensile strength at sub-millimetre gauge lengths [PDF]

, 2001
The strength of composite reinforcement fibres is normally measured on samples of much greater length than the actual residual fibre lengths found in many composite materials.

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

A Novel Decellularized Fibrocartilage Graft Promotes Tympanic Membrane Repair

Advanced Healthcare Materials, EarlyView.
An off‐the‐shelf decellularized porcine meniscus fibrocartilage graft (MEND) is engineered for pediatric tympanoplasty. Featuring a microchannel architecture that promotes host cell invasion, MEND rapidly closes tympanic membrane perforations and fully remodels in vivo, outperforming fascia and matching cartilage grafts while avoiding donor‐site ...

Concave Diffraction Gratings by High-Precision Injection Moulding

Proceedings, 2019
As an example of the applicable process chain, a concave grating (1175 grooves/mm) with an active area of approx. 24 mm to 24 mm has been replicated by means of electroplating and further by injection moulding with polycarbonate, resulting in a surface ...

The influence of fibre length, diameter and concentration on the strength and strain to failure of glass fibre-reinforced polyamide 6,6 [PDF]

, 2008
Results of an investigation of the mechanical performance of injection moulded long glass fibre-reinforced polyamide 6,6 composites are presented. The glass fibre content in these composites was varied over the range 10-50% by weight using fibres with ...

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Mechanical properties and chemical stability of pivalolactone-based poly(ether ester)s [PDF]

, 1994
The processing, mechanical and chemical properties of poly(ether ester)s, prepared from pivalolactone (PVL), 1,4-butanediol (4G) and dimethyl terephthalate (DMT), were studied. The poly(ether ester)s could easily be processed by injection moulding, owing
