The development of novel smart colour change polymer materials via various melt processing techniques
(Athlone Institute of Technology, 2020-06)Smart polymers or stimuli-responsive polymers undergo large reversible changes, whether physical or chemical, in their properties as a consequence of small environmental variations. They can respond to a single stimulus ... -
Modification of hyaluronic acid for stereolithography 3D printing of hydrogel nerve conduits
(Athlone Institute of Technology, 2020-06)The peripheral nervous system transmits signals from the brain to the limbs and organs of the body. Peripheral nerve injuries (PNIs) resulting from trauma, illness or cancer affect approximately 1 million people in Europe ... -
Development of biphasic drug delivery PVA/propolis electrospun nanofibres
(Athlone Institute of Technology, 2020-06)The integration of nanotechnology into biomedical applications is called “nanomedicine”. Nanomedicine has the ability to change properties of materials at the molecular and atomic level [1]. Numerous methods have been ... -
Purified β‐glucans from the Shiitake mushroom ameliorates antibiotic‐resistant Klebsiella pneumoniae‐induced pulmonary sepsis
(Society for Applied Microbiology, 2020-07-24)Bacterial infection remains the main cause of acute respiratory distress syndrome and is a leading cause of death and disability in critically ill patients. Here we report on the use of purified β‐glucan (lentinan) extracts ... -
Effect of stereolithography 3D printing on the properties of PEGDMA hydrogels.
(MDPI, 2020-09-03)Stereolithography (SLA)-based 3D printing has proven to have several advantages over traditional fabrication techniques as it allows for the control of hydrogel synthesis at a very high resolution, making possible the ... -
Preclinical assessment of biomimetic and bioactive bone regeneration scaffold in femoral condyle defect of Sprague Dawley rats.
(Athlone Institute of Technology, 2020)A fabricated biomimetic bone scaffold, incorporating osteogenic factors, presents a promising alternative to traditional autologous and allogeneic bone fracture treatments. Here, the principles of biology and engineering ... -
Fused-filament fabrication of PEEK: a review of process-structure-property relationships.
(MDPI, 2020-07-27)Poly (ether ether ketone) (PEEK) is a high-performance engineering thermoplastic polymer with potential for use in a variety of metal replacement applications due to its high strength to weight ratio. This combination ... -
Enzymatic activities and analysis of a mycelium-based composite formation using peach palm (Bactris gasipaes) residues on Lentinula edodes.
(Research Square, 2020-08-03)By seeding fungus on top of industry residues, a mycelium can grow and form a compacted network structure, producing a material whose properties can be quite similar to polystyrene. However, depending on the source used, ... -
Development of alginate beads with encapsulated jabuticaba peel and propolis extracts to achieve a new natural colorant antioxidant additive.
(Elsevier, 2020-07)This work aims to encapsulate anthocyanins and phenolic compounds extracted from a native Brazilian fruit peel - jabuticaba (Plinia cauliflora (Mart.) Kausel) and propolis from Tubuna (Scaptotrigona bipunctata) stingless ... -
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 ... -
Injectable bone substitute based on chitosan with polyethylene glycol polymeric solution and biphasic calcium phosphate microspheres.
(Elsevier, 2020-06-10)We described a method to produce an injectable bone substitute consisting of a solid and liquid phase, this solid was formed using the coacervation method consisting of a mixture of Hydroxyapatite (HAp) and beta-Tricalcium ... -
Effect of cullulose size-concentration on the structure of polyvinyl alcohol hydrogels.
(Elsevier, 2020-06-11)Microfibrillated cellulose as a reinforcement agent has been investigated extensively due to their unique characteristics, which can reorder the structure of polymers and hydrogels leading to improved mechanical properties ... -
Impact of torrefaction on properties of Miscanthus x giganteus relevant to gasification.
(Elsevier, 2014-04-01)Miscanthus × giganteus (M × G) was torrefied to improve its thermal and physical properties prior to thermal conversion. Torrefaction was undertaken at a series of temperatures from 230 to 290 °C for residence times varying ... -
Development of disulfiram-loaded vaginal rings for the localised treatment of cervical cancer.
(Elsevier, 2014-11)Cervical cancer is the third most prevalent cancer in women and disproportionately affects those in low resource settings due to limited programs for screening and prevention. In the developed world treatment for the disease ... -
The production of solid dosage forms from non-degradable polymers.
(Bentham Science, 2015)Non-degradable polymers have an important function in medicine. Solid dosage forms for longer term implantation require to be constructed from materials that will not degrade or erode over time and also offer the utmost ... -
Evaluation of the early in vivo response of a functionally graded macroporous scaffold in an osteochondral defect in a rabbit model.
(Springer, 2016-05)Cartilage tissue engineering is a multifactorial problem requiring a wide range of material property requirements from provision of biological cues to facilitation of mechanical support in load-bearing diarthrodial joints. ... -
