Vascular grafting has been an effective remedy to vascular diseases for decades. Autografting by using the veins or arteries in the patient’s body is found to have patency rate for years. However, autografting may not be possible when compatible vessels are not available. In this case, synthetic vascular grafts are found to be effective replacements. Nevertheless, synthetic grafts with diameter less than 4 mm becomes challenging due to thrombogenicity and mismatch of mechanical properties with the native vessels. Along this line, the ability to develop new biostable synthetic materials suitable for smaller grafts and the ability to evaluate their resulting …

The present research is aimed to investigate the effect of varying the carbonate to phosphate (CO32−/ PO43‒) molar ratios from 0.5 to 5 on the physical and mechanical properties of carbonated hydroxyapatite (CHA) synthesized by a wet chemical method. The sintering was performed under dry carbon dioxide atmosphere at 900 °C to maintain the B-type CHA structure. It was found that increases in CO32−/ PO43‒ ratio was accompanied by an increase in the c/a lattice ratio. The diffraction peaks of the synthesized 0.5-5 CHA powders exhibited a single phase material except for 5CHA which revealed the some minor calcite or …
Poly(Vinyl Alcohol)/Α-Chitin/Nanocellulose Composites Developed From Oil Palm Empty Fruit Bunch (Opefb) For Removal Of Cationic Dyes, Chun Fah Mok
Student Works (2020-2029)
In search of an eco-friendly polymeric adsorbent for dye effluent treatment application, poly(vinyl alcohol) (PVA)/chitin/nanocellulose composites were synthesized. The composites were reinforced by oil palm empty fruit bunch fibers (OPEFB)-derived nanocrystalline cellulose (NCC). With addition of 1 wt.% NCC, a maximum improvement of 57.64% and 50.66% in tensile strength and Young’s Modulus were achieved, respectively. However, the PVA-based composites exhibited low resistance in aqueous medium. Hence, maleic acid (MA) was incorporated, in view of modifying PVA-based composites through cross-linking reactions. The effect of varying chitin content (10 wt.%-30 wt.%) and MA content (10%-50% based on total solid content of composite) …

Acute myocardial infarction (AMI), also termed as heart attack, is often clinically screened by blood test through the measurement of cardiac biomarkers (i.e., troponin (T or I), creatine kinase (CK−MB) and myoglobin) and electrocardiography (ECG) changes which are presented to the hospital. However, the early diagnosis of AMI is challenging because the detection of biomarkers such as troponin (T or I) and CK−MB are only reliable at the intermediate and later stages (> 6 hours after chest pain onset), during myocardial injury and myocardial infarction. On the other hand, myoglobin often been used as early biomarker which is detectable within …

Bacteriorhodopsin is a photoactive protein found in the purple membranes of the highly halophilic bacterium Halobacterium Salinarium. Due to highly efficient and simple in its function, Bacteriorhodopsin has been extensively researched and successfully incorporated into many practical applications. In this regard, the fabrication of compactly packed and functionally active Bacteriorhodopsin thin film is crucial in realizing a highly efficient device. The aim of this thesis is to analyze the mechanical and thermodynamic properties of the Bacteriorhodopsin-Langmuir monolayer film from the surface pressure-area per molecule isotherm to produce a compactly pact and functionally active monolayer film. For this, we have proposed …
