Controlling mass loss from RTM6 epoxy resin under simulated vacuum infusion conditions Open
A certified aerospace resin (RTM 6) normally utilised for resin transfer moulding is considered for vacuum infusion. The resin was subjected to simulated vacuum infusion conditions by using a specialised thermogravimetric analysis that ena…
Characterisation of bone regeneration in 3D printed ductile PCL/PEG/hydroxyapatite scaffolds with high ceramic microparticle concentrations Open
3D printed flexible and ductile composite scaffolds with high ceramic particle concentrations and their in vivo bone regeneration performance.
Preparation and characterization of composites using blends of divinylbenzene‐based hyperbranched and linear functionalized polymers Open
In this study, hyperbranched polymers were explored as matrix modifiers to create E‐glass fiber (GF) reinforced polymer composites with enhanced mechanical properties. Hyperbranched polymers have lower viscosities than their linear equival…
Modification and Application of Albizia lebbeck Sawdust For The Sorption of Lead(II) and Copper(II) From Aqueous Solutions Open
Oriental Journal of Chemistry is a peer reviewed quarterly research journal of pure and applied chemistry. It publishes standard research papers in almost all thrust areas of current chemistry of academic and commercial importance. It prov…
Effect of dissolution rate and subsequent ion release on cytocompatibility properties of borophosphate glasses Open
Present work explores the relationship between the composition, dissolution rate, ion release and cytocompatibility of a series of borophosphate glasses. While, the base glass was selected to be 40mol%P 2 O 5- 16mol%CaO-24mol%MgO-20mol%Na …
Improved phosphate‐based glass fiber performance achieved through acid etch/polydopamine treatment Open
Phosphate‐based glass fibers (PGF) are of interest as reinforcements for degradable implants, but have seen limited application due to their rapid loss of strength when subjected to aqueous conditions. Previous studies have utilized heat t…
The effect of MgO/TiO<sub><b>2</b></sub> on structural and crystallization behavior of near invert phosphate‐based glasses Open
Varying formulations in the glass system of 40P 2 O 5 ─(24 − x )MgO─(16 + x )CaO─(20 − y )Na 2 O─ y TiO 2 (where 0 ≤ x ≤ 22 and y = 0 or 1) were prepared via melt‐quenching. The structure of the glasses was confirmed by X‐ray diffraction (…
