Self-photopolymerizable hydrogel-ceramic composites with scavenger properties
(MDPI, 2022-03-21)
The photocatalytic behaviours of semiconductive ceramic nanoparticles such as TiO2
, ZnO,
Fe2O3
, and Fe3O4
, have been extensively studied in photocatalysis and photopolymerization, due to
their ability to produce ...
Material considerations for fused-filament fabrication of solid dosage forms.
(MDPI, 2018-04-02)
Material choice is a fundamental consideration when it comes to designing a solid dosage form. The matrix material will ultimately determine the rate of drug release since the physical properties (solubility, viscosity, ...
Characteristics of the treated calcium carbonate particles with stearic acid using different treating methods.
(Elsevier, 2016-08)
Calcium carbonate (CaCO3) is often treated with stearic acid (SA) to decrease its polarity. However, the method of application of the SA treatments has a strong influence on their interface structure and distribution. ...
Process optimization for the 3D printing of PLA and HNT composites with Arburg plastic freeforming
(MDPI, 2022-10-12)
The industrial use of additive manufacturing continues to rapidly increase as new technology
developments become available. The Arburg plastic freeforming (APF) process is designed to
utilize standard polymeric granules ...
Polymer based additive manufacturing historical developments, process types and material considerations.
(Springer Nature, 2019)
3D printing is a manufacturing technique where parts are built in a layer-by-layer fashion. The earliest embodiments were based on generating successive layers of solidified materials at the air liquid interface through ...
Synthesis and characterisation of novel n-vinyl pyrrolidinone/acrylic acid copolymers for use in biomedical applications.
(2006)
The aim of this study was to develop a novel hydrophilic polymer for use in biomedical applications. The polymers synthesised in this work were based on the monomers N-vinyl pyrrolidinone (NVP) and acrylic acid (AA) and ...
3D printed polymers are less stable than injection moulded counterparts when exposed to terminal sterilization processes using novel vaporized hydrogen peroxide and electron beam processes.
(Elsevier, 2019-11-21)
There is an increasing trend for use of 3D printing processes in healthcare due in part to emergence of customised medical devices and associated low manufacturing cost. However, there is a dearth of knowledge on the ...
Photopolymerization for filling porous ceramic matrix: improvement of mechanical properties and drug delivering behaviour.
(Wiley, 2019-04)
This work presents the photopolymerisation of composite scaffolds where a prefabricated ceramic scaffold was impregnated with poly(ethylene) glycol dimethacrylate (PEGDMA) macromonomer solution. The PEGDMA solution penetrates ...
Orthopaedic 3D printing in orthopaedic medicine.
(Springer, 2019-09-17)
Orthopaedic surgeries are commonly extremely challenging, and innovations are required to overcome a series of recognised difficulties and improve patient outcomes. Complications, in particular, the high occurrence of ...
Review of catheter-associated urinary tract infections and in vitro tract models.
(Hindawi, 2018-10)
Catheter-associated urinary tract infections (CAUTIs) are one of the most common nosocomial infections and can lead to numerous medical complications from the mild catheter encrustation and bladder stones to the severe ...
