During the COVID-19 era, most countries, including Malaysia, have shifted from face-to-face teaching systems to online teaching programs. The aim of this study is to identify the main challenges that higher education students face during e-learning based on their residential location throughout Peninsular Malaysia. This study further examines the readiness of higher education students to apply e-learning. Therefore, a cross-sectional survey approach is used to fulfil the outlined objectives. Accordingly, 761 public (95.3%) and private (4.7%) higher education students residing in Peninsular Malaysia are sampled in this study. The survey was administered online for 37 days, from 21 October 21 to 6 December 2021, using either WhatsApp or Facebook. The raw data is inferentially (Principal Component Analysis, K-Means Clustering, Kruskal Wallis, and spatial analysis) and descriptively (mean, standard deviation & percentage) analyzed. It has been revealed that six clusters of students in Peni.....

This study fabricated tantalum (Ta)-doped titanium dioxide with a unique nanorod-assembled actinomorphic-flower-like microsphere structured film. The Ta-doped TiO2 actinomorphic-flower-like microsphere (TAFM) was fabricated via the solution immersion method in a Schott bottle with a home-made improvised clamp. The samples were characterised using FESEM, HRTEM, XRD, Raman, XPS, and Hall effect measurements for their structural and electrical properties. Compared to the undoped sample, the rutile-phased TAFM sample had finer nanorods with an average 42 nm diameter assembled to form microsphere-like structures. It also had higher oxygen vacancy sites, electron concentration, and mobility. In addition, a reversed double-beam photoacoustic spectroscopy measurement was performed for TAFM, revealing that the sample had a high electron trap density of up to 2.5 ?molg?1. The TAFM showed promising results when employed as the resistive-type sensing film for a humidity sensor, with the highest se.....

Oily wastewater (OW) is detrimental towards the environment and human health. The complex composition of OW needs an advanced treatment, such as membrane technology. Membrane distillation (MD) gives the highest rejection percentage of pollutants in wastewater, as the membrane only allows the vapor to pass its microporous membrane. However, the commercial membranes on the market are less efficient in treating OW, as they are prone to fouling. Thus, the best membrane must be identified to treat OW effectively. This study tested and compared the separation performance of different membranes, comparing the pressure-driven performance between the membrane filtration and MD. In this study, several ultrafiltration (UF) and nanofiltration (NF) membranes (NFS, NFX, XT, MT, GC and FILMTEC) were tested for their performance in treating OW (100 ppm). The XT and MT membranes (UF membrane) with contact angles of 70.4 0.2 and 69.6 0.26, respectively, showed the best performance with high flux and oil.....

Introduction: Dexamethasone is a type of drug that is considered a steroid. It belongs to a class of drugs known as corticosteroids. Objective: Develop an electrochemical sensor of dexamethasone in a pharmaceutical sample using electrodes modified with nanostructures of MnO2 and reduced graphene oxide (MnO2/rGO). The glassy carbon electrodes (GCE) used to make the GO nanostructures were first modified using a modified Hummers technique before electrochemically reduced. Methods: MnO2 nanomaterials were electrochemi-cally deposited on rGO/GCE. SEM structural investigation indicated vertical tetragonal crystal development of-MnO2 nanostructures in sprayed rGO nanostructures. Results: Because of the high composite surface area, multiple exposed active sites, and the synergistic effect of MnO2 and rGO, the electrocatalytic reaction to dexamethasone of MnO2/rGO/CPE was shown to be broad, selective, stable, and sensitive in electrochemical tests using amperometry. It was established that the .....

In China, secondary school students studying at the vocational stream often struggle to keep up with English language learning. This study investigates the relationship between two types of motivation extrinsic and intrinsic towards the English language test performance of students from a secondary vocational school in Chongqing, China. A mixed-method research design was employed via a survey and a semi-structured interview. A total of 212 second-grade students at randomly selected secondary vocational schools completed the questionnaire. A correlational analysis was performed to discover if there was a relationship between students extrinsic and intrinsic motivation towards their English performance. The results reveal that the intrinsic motivation was strongly correlated with the students English performance with r=0.216, p0.05. A multiple linear regression analysis was also conducted to investigate the extent that students intrinsic and extrinsic motivation predicted their English p.....

Good public transportation that can offer a pleasant peaceful and relaxing environment is necessary for improving people's interest in using it. Thermal comfort is determined in this study by measuring the air velocity and temperature of the air-conditioning from the outlet. Both data are taken using a digital anemometer and thermocouple with three replications for reproducibility. For data collection, a 10-row shuttle bus was held immobile for 30 minutes. According to the data, outlet 5 received the highest air velocity and the lowest temperature, at 9.12 ms-1 and 13.6 C, respectively. It was also discovered that the design of the air-conditioning ducting impacts the reachability of cooled air to the farthest outlets, adversely affecting the target cool temperature and passenger comfortability. It is suggested that in order to promote the attractiveness of public transportation, the inner bus compartment and air-conditioning system in hot countries should prioritise thermal comfort. 2.....
