The integration of MoS₂ has been applied in almost every type of solar cells as a hole transport layer (HTL), electron blocking layer (EBL), back contact, hole transport material (HTM) and a counter electrode (CE) that heavenly result in enhancement of the power conversion efficiency (PCE). Despite of the above-mentioned improvement, the existence of MoS₂ in the cells still liable to issues and drawbacks in the performance for specific device’s configuration. Thus, this paper is not only covers the fundamental aspects of MoS₂ in solar cells application but also identify the gaps and issues for further understanding by highlighting on its advantages and limitation. The current research on the synthesis and its application are also emphasized.

Internet of Things (IoT) technology has attracted much attention in recent years for its potential to increase and optimize the performance of monitoring and control of engineering and non-engineering application. The challenges in the integration process of IoT in different application is a key issue limiting progress in this area, thus this paper discussed the area, technologies, challenges, and opportunities for IoT in domestic and industrial applications.

This paper presents the research relating to each area of the model, evaluating their strengths, weaknesses, and overall suitability for IoT system in different area. Challenges that IoT faces including security, reliability, robustness, cost, and low-power operation are presented, and recommendations are made for future research directions

In year 2020 the global experience health and economic crisis due to the COVID-19 pandemic. Digital Technologies are awakening in countries across the world to fight this global crisis, which, in one way or another, strongly relies on the availability of wireless communication systems. This talk looks into the role of wireless communications during COVID-19 pandemic from different perspectives. How wireless communication technologies are be used to combat this pandemic, including monitoring of the virus spread, enabling healthcare automation, and allowing virtual education and conferencing. The importance of digital inclusiveness in the pandemic and possible solutions to connect the unconnected becomes a vital role. The challenges faced when using wireless technologies, including privacy, security, and misinformation will be presented, which will reveal how the developed technologies during the pandemic can be helpful in the post-pandemic era.

Robust engineering deals with engineered quality with the aim to optimize for robust function. In the fabrication process of a 12nm Gate Oxide semiconductor, sensitive Electrostatic Discharge (ESD) has been found to be the major causes that deteriorate the final product quality. Control measures on people, grounding and ionizations have been commonly implemented as the main preventive actions against ESD. However, many aspects of the measures need to be tailored to the specific machines, technology and fabrication facility. This paper reports on the findings based on robust engineering approach conducted to identify the effectiveness of groundings and ionizations as countermeasures against ESD on the back-end process of a specific 12nm Gate Oxide semiconductor fabrication facility. The results affirm the need to treat each process and facility as a unique entity where the suitability of the ESD countermeasures need to be determined empirically.

In this paper, a systematic study of the effect of inter-structural gap between a series of in-line Mach-Zehnder interferometers (ILMZIs) is presented. Two similar ILMZIs, composed of a pair of fiber micro-bottles 3.5 cm apart, were fabricated and spliced in series by performing fusion splicing of a standard single-mode fiber using a commercial machine. The quality of the collective transmission spectrum of this serial formation is affected by the remnant cladding mode transmitted from preceding ILMZI. This study shows that there is a plain minimum structural gap of approximately 40 cm between the cascaded ILMIs to achieve a ripple-free resultant spectrum while retaining a broad free spectral range (FSR) of ~20 nm. It is also discovered that the minimum structural gap can be reduced by half by simply bending the connecting fiber for inducing sufficient loss to eliminate the remnant cladding mode, demonstrated with a curvature radius around 1.25 cm over only a short length of ~2.3 cm. This finding allows construction of a more compact architecture of serial ILMZIs based on fiber micro-bottles, with pristine interference spectrum, broad FSR and a high extinction ratio, which can be exploited as a new approach for spectrum shaping, multi-parameter sensing and wide dynamic range sensing.

Shortage of water has become a predominant problem all over the world. Water plays a very important role in agriculture sector, domestic and industry. In certain area of the world, farmers are facing problems on watering their crops especially during dry season. They cannot depend on on the remaining water sources and the watering process efficiency is low which will affect the plant growth. Intelligent irrigation system using Rain Water Harvesting (RWH) and Fuzzy Interface System (FIS) is used for the crops watering process. The RWH is a system that collecting, concentrating and storing rain water. The study consists of development of RWH and intelligent irrigation system using Fuzzy Logic Interface. Building rooftop catchment is used which is enough for small farm crops watering purposes. The intelligent irrigation system will ensure that, the output of the water can be controlled and the watering of crops become efficiency. The FIS which used temperature & humidity and soil moisture sensor will determine the timing and amount needed for the watering process. The result that the system can help reduce the water usage and RWH is enough for small farm usage. This will improve the farm water source efficiency and sustainable. The developed project is currently operating at INSAT i.e. UniMAP-owned agricultural research institute

One of the earliest known and most investigated materials was Barium Titanate. The early days focus on its ferroelectricity and subsequently its piezoelectricity resulted in widespread applications as a piezo-transducer as well as a radar material, but co-substituted with Strontium. Its popularity was supplanted by Lead Titanate, and as the world began to be environmentally conscious, re-emerged for a myriad of new applications. In optical communications Lithium Niobate took centre-stage as a modulator of choice due to its ease of production but currently BariumTitanate being investigated for its use in photonics. Its non-centrosymmetric bulk structure exhibits optical birefringence with the ordinary and extraordinary refractive indices, n_o and n_e. Modern applications for this perovskite structured material depend on its thickness as much as its preparation / deposition method. However the greatest challenge for Barium Titanate will be successful integration with Silicon. Barium Titanate is usually consolidated or annealed at above 800 ⁰C which is beyond Silicon processing temperatures. Some possible insight for this integration may be via a lowered annealing temperature or separately fabricated and wafer bonded at a later stage.
