Synthesis of linear aliphatic polycarbonate macroglycols using dimethylcarbonate.
(Wiley, 2009-01-05)A series of linear aliphatic polycarbonate polyols were synthesized using dimethylcarbonate and a linear alkane diol or specific combinations of linear alkane diols. Polyol synthesis was carried out in a two‐stage process ... -
Effect of Chemical Treatments and HDPE-g-MA on the physical and mechanical behaviour of HDPE/ natural fibre composites.
(2013)Many authors have reported on the use of natural fibres (raw or chemically modified) as reinforcing elements for high density polyethylene (HDPE). These materials have generated a lot of interest due to their low cost ... -
Development of synthetic alternatives for bone tissue engineering.
(Australian Journal of Basic and Applied Sciences, 2013)Due to the inherent limitations of current biological bone grafts, alternative synthetic substitutes are being pursued. Therefore, this study aimed to improve the bioactive and compressive properties of photopolymerisable ... -
Processing and characterisation of various polymer blends to develop implant for tissue engineering applications.
(AESS, 2013)In the past two decades, the repair and reconstruction of musculoskeletal tissues using biodegradable scaffold materials has emerged as one of the most promising approaches in tissue engineering. The aim of this study ... -
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 ... -
Preparation and characterization of novel poly(vinyl) (alcohol) (PVA) and poly(acrylic acid) (PAA) hydrogels for sensitive hydrogels.
(Sciforum, 2014-05)Stimuli Sensitive hydrogels have enormous potential in various applications. Various environmental variables are found in the body, such as low pH and elevated temperatures. For this reason, either pH-sensitive and/or ... -
Analysis of the mechanical properties of solvent cast blends of PLA/PCL.
(Trans Tech Publications, 2014-09)Polylactic acid (PLA) is the most promising material in the biodegradable category. However, brittleness and poor thermal stability restrict its application. To overcome this limitation, PLA may be blended with other ... -
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 ... -
In vitro fibroblast and pre-osteoblastic cellular responses on laser surface modified Ti-6AI-4V.
(IOP Publishing, 2014-12-29)The success of any implant, dental or orthopaedic, is driven by the interaction of implant material with the surrounding tissue. In this context, the nature of the implant surface plays a direct role in determining the ... -
Smart thermosensitive poly (N-vinylcaprolactam) based hydrogels for biomedical applications.
(AENSI, 2014-12-31)Photopolymerisation is an attractive technique used in biomedical applications as it can provide rapid reaction rates with excellent temporal and spatial control features and unique tuneable properties. This fabrication ... -
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 ... -

Review of multifarious applications of Poly (lactic acid)
(Taylor & Francis, 2016)Poly (lactic acid) is considered to be a promising alternative to petroleum-based polymers due to its renewability, biodegradability, biocompatibility, and good mechanical properties. Because of the high cost, the applications ... -
Reinforced polylactic acid for use in high strength biodegradable medical implants.
(2016)Traditional medical implants, such as orthopedic screws, pins, and coronary stents, are almost exclusively metallic due to high mechanical strength requirements. However, issues related to the use of permanent metallic ... -
Extraction method plays critical role in antibacterial activity of propolis loaded hydrogels.
