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 ... -
Dielectric polarization enhancement of thermoplastic elastomers for sensing and energy harvesting applications.
(IJMMM, 2016-11)Nano-structured dielectric thermoplastic elastomers (DTEs) such as poly(styrene-co-ethylene-co-butylene-styrene) [SEBS] and poly(styrene-co-ethylene-co-butylene-styrene) –grafted- maleic anhydride[SEBS-g-MA] triblock ... -
Effect of anodizing time on the mechanical properties of porous titania coatings formed by micro-arc oxidation.
(Elsevier, 2017-01-15)Porous TiO2 coatings were produced on commercially pure Ti substrates by micro-arc oxidation (MAO) in 1.0 M H2SO4 electrolyte for different anodizing times. Their mechanical properties were assessed by means of instrumented ... -
Effect of unidirectional freezing using a thermal camera on polyvinyl (alchohol) for aligned porous cyrogels.
(Taylor & Francis Online, 2020-03-18)Unidirectional freeze casting for polymers and ceramics has been performed extensively; however, the mechanisms involved in unidirectional freezing are not thoroughly understood and therefore, in this study, polyvinyl ... -
Enhancement of mechanical properties and wettability of TiO2NT arrays formed in simulated body fluid‐based electrolyte.
(Wiley, 2019-09-13)Modified titanium nanotubes (TiO2NTs) coatings are grown in simulated body fluid (SBF) from Ticp and Ti6Al4V. The addition of 1% v/v of SBF to the electrolyte neither modifies film morphology nor the structural oxide ... -
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, ... -
Evaluation and characterisation of urinary catheter coating utilising Hansen solubility parameters and FEA analysis.
(Elsevier, 2015-08-15)This work investigated the Hansen solubility parameters required to optimise a functional polyurethane base coat as an attachment for a lubricious polyvinyl pyrrolidone coating for polyvinyl chloride urinary catheters. ... -
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. ... -
The evaluation of the potential ecotoxicity of pyroligenous acid obtained from fast pyrolsis.
(Elsevier, 2019-09-30)Pyroligneous acid (PA) is a by-product of bio-oil, which is obtained by pyrolysis of the wood. This product has been tested for use in several areas, such as agriculture, as a promising green herbicide; however, there are ... -
Freeze-thaw electrospun PVA-Dacarbazine nanoparticles: preparation, characterization and anticancer evalution.
