Thermal Diffusivity of Glass Ceramic Synthesized from Soda Lime and Coal Fly Ash

Glass ceramics are polycrystalline materials of fine microstructure that are produced by the controlled crystallization of a glass. The previous review of other researchers revealed that knowledge and expertise has been accumulated on the process of transformation of silicate waste into useful glass ceramic products. The aim of this research is to study the thermal diffusivity of a glass ceramic made from a mixture of soda lime silica and coal fly ash. The effect of sample compression pressure, sintering temperature and sample composition on the thermal diffusivity value was investigated in detail. All samples were measured using the Laser Flash Apparatus (LFA), X-Ray Fluorescence (XRF), Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD). It was found that the thermal diffusivity value of the samples is dependent on the pressure, sintering temperature and sample composition. Higher sintering temperature, coal fly ash content and compression pressure resulted in higher thermal diffusivity value. The experimental results showed that the thermal diffusivity value is in the range of 0.102 mm2/s to 0.858 mm2/s. As the ambient temperature increased from room temperature up to 300°C, the thermal diffusivity values were also increased. This suggests that thermal diffusivity is basically influenced by phonon interaction that determines the phonon mean free path. The density value and linear shrinkage increase as the coal fly ash content and sintering temperature increased. XRD results revealed the formation of Diopside (CaMgO6Si2) and Wollastonite (CaSiO3) phases

Thermal diffusivity measurement of SnO2-CuO ceramic at room temperature

Thermal diffusivity is a measure of rapidity of heat propagation through a material. The property is important in the understanding of gas sensor performance. Photoflash technique was used to determine thermal diffusivity of SnO2-based materials with varying amount of CuO ranging from 10 to 50 mol%, at room temperature. The samples were made disc-shaped, 10 mm in diameter with thickness ranging from 2.4 to 2.8 mm. We found that the thermal diffusivity values of SnO2-CuO samples ranging from 6.21 to 7.51×10-2 cm2z-1 were better than the reported thermal diffusivity value of pure SnO2 sample (1.45×10-2 cm2Z-1). The thermal diffusivity behaviour was supported by results from XRD and SEM

Study of Ammonia-Nitrogen and Phosphorus in Parit Rasipan Canal During the Wet Season

The Parit Rasipan Canal's deteriorating water quality and eutrophication are both blamed on ammonia-nitrogen and phosphorus. In order to conserve freshwater resources, it is crucial to understand the relationship between land use and water quality. It is also crucial to evaluate how land use affects the pollutants load. In this study, eutrophication along the Parit Rasipan drainage system will be identified, water quality will be investigated in terms of phosphorus and ammonia nitrogen concentration and classified according to land use type during the wet season, and ammonia-nitrogen and phosphorus concentrations will be compared with Normalized Difference Vegetation Index (NDVI) using unmanned aerial vehicles (UAV). At a specific location along the Parit Rasipan drainage system, samples were taken. The USEPA PhosVer 3 with Acid Persulfate Digestion Procedure (Method 8190) and Nessler's Method (Method 8038) were used, respectively, to measure phosphorus and ammonia nitrogen. Ammonia nitrogen and phosphorus final effluent concentrations ranged from 3.21 mg/L to 5.96 mg/L and 0.36 mg/L to 1.55 mg/L, respectively. The residential area's water, on the other hand, had significant concentrations of ammonia, nitrogen, and phosphorus, which contributed to eutrophication in the wake of industrial, agricultural, and farming activities

Antibacterial properties of Kelulut, Tualang and Acacia honey against fourteen clinically-isolated strains of bacteria-infecting wound

Bacterial infection is the most common cause of prolonged wound healing period. Honey has been known as an effective antibacterial agent due to its peroxide and non-peroxide activities to prevent bacterial infection. This study aims to investigate antibacterial property of three varieties of Malaysian honey represented by two multifloral; Kelulut and Tualang, and one monofloral; Acacia against fourteen isolated bacteria from wounds of three patients. Agar well diffusion assay was used to screen the antibacterial property of these honey. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were performed for antibacterial evaluation at a concentration range of 60% (w/v) to 5% (w/v). This method was utilised to analyse the total and non-peroxide activities of the honey against all clinically isolated bacterial strains. The initial screening has demonstrated Kelulut as a strong antibacterial agent than Tualang and Acacia which was comparable to medical-grade Manuka (UMF 18+). The MICs for Kelulut, Tualang, and Acacia were observed to range from 5% (w/v) to 12.5% (w/v), 12.5% (w/v) to 30% (w/v), and 25% (w/v) to 50% (w/v) respectively, while the range was between 5% (w/v) and 15% (w/v) for Manuka. The difference for peroxide and non-peroxide activities recorded were statistically significant (p<0.05) for Kelulut, Tualang, and Manuka, excluding Acacia. Malaysian honey do possess antibacterial property against clinically isolated bacteria from wound in which Kelulut honey was identified to have a close similarity to the medical-grade Manuka. Based on our results, Kelulut has shown the strongest antibacterial activity and can be considered as one of the alternative treatments to reduce the healing period of infected wound
