https://jasetm.fisat.ac.in/index.php/jasetm/article/view/20
<p>Microstrip bandpass filters have been the subject of research for a very long period to suit the needs of contemporary multiservice wireless communication systems. Multiband bandpass filters, or BPFs, are necessary for the receiver front end to work as a single unit that can serve many bands simultaneously. Particularly promising are the compact design, low integration cost, and simplicity of manufacture using printed circuit technology of planar bandpass filters. The design and implementation of filters for fifth-generation (5G) mobile communication systems is complicated due to the necessity for high integration, low cost, and high-speed data transfer. This paper offers and discusses a comprehensive assessment of existing research on microstrip single multiband bandpass filter designs for fifth-generation applications, with an emphasis on the most recent advances.</p>Anitha GeorgeAnju IqubalAbdulla P

2024-06-212024-06-2122091410.61779/jasetm.v2i2.2A survey on the need to incorporate rainwater harvesting systems as an alternative domestic water source in Ghana
https://jasetm.fisat.ac.in/index.php/jasetm/article/view/32
<p><em>This research survey seeks to gather responses in rainwater gathering and storage using harvesting systems as a key alternative. About 502 responses were gathered. Averaging 8 persons per household and 6 rooms per household. 73.1 % of males and 26.9 females. The main source of water includes GWCL (37.8 %), Borehole/groundwater (59.6 %), both GWCL & Borehole (1 %), Both Rainwater & GWCL (1 %), other unspecified sources (0.6 %). 58.2 % responded ‘Yes’ to the collection of rainwater to 41.8 ‘No’ responses. Methods for collecting rainwater includes roof gutter & drain spouts (37.8 %), open containers (40.8 %), other unspecified means (14.7 %). 56.8 % said ‘YES’, with about 2 % saying ‘IF THE NEED BE’ and 41.2 % responding ‘NO’ to the need to collect rainwater for future use. Roofs age also contribute to water quality, 45.2 % were above 10 years, 30.7 % between 7-10 years, 14.3 % between 4-6 years and 9.8 % between 1-3 years. Furthermore, 65.3 % respondents had heard of rainwater harvester systems. About 75.7 % responded to ‘NO’ for not having rainwater systems installed. About 83.3 % responded ‘NO’ to treating the collected water before use. About 64.1% are willing to treat the harvested rainwater. About 61.4 % respondents indicated the reduction in their water bill. The t-statistic and P-value results suggested collecting rainwater does not appear to be associated with a difference in the number of rooms in a household. The Chi-square statistic of 14.394 and a P-value of 0.000148 establishes a strong association between collecting rainwater at the household during the rainy seasons and seeing a reduction in water bills during the rainy season compared to reliance on traditional water supplies alone. Households that collect rainwater are significantly more likely to see a reduction in their water bills. There is a growing interest in the gathering, harvesting and the purification of rainwater for domestic use as a great alternative.</em></p>Duke Mensah Bonsu ANTWIIsaac Kwadwo AMANKWAAAmi JohannesEmmanuel AgyekumDaniel AMANIAMPONGTheophilus Ofori AGYEKUMHarriet Kwakye BOATENG

https://jasetm.fisat.ac.in/index.php/jasetm/article/view/34
<p><strong>Tin oxide (SnO₂) nanoparticles are of significant interest due to their unique properties and diverse applications. In this study, pristine and Zn-doped SnO₂ nanoparticles (with Zn doping levels of 1.9 wt% and 3.7 wt%) were successfully synthesized using the co-precipitation method, followed by annealing at 500 °C for 5 hours. X-ray diffraction (XRD) analysis confirmed that all samples exhibited a tetragonal cassiterite structure, with crystallite sizes ranging from 22.5 nm to 28.2 nm, consistent with values obtained from the Williamson-Hall (W-H) plot. The nanoparticles demonstrated preferential orientation along the (110), (101), and (211) planes. Scanning Electron Microscopy (SEM) showed that the Zn-doped SnO₂ nanoparticles had a denser microstructure compared to the pristine samples. The energy band gap, as determined by diffuse reflectance spectroscopy, was found to be in the range of 3.10 eV to 3.16 eV. Fourier Transform Infrared (FTIR) spectroscopy revealed characteristic peaks at 459 cm⁻¹, 604 cm⁻¹, 924 cm⁻¹, 1976 cm⁻¹, 2117 cm⁻¹, and 3651 cm⁻¹, corresponding to the vibrations of various functional groups present in the material. </strong></p>Anisha JosephS Deepa

https://jasetm.fisat.ac.in/index.php/jasetm/article/view/36
<p>Materials in the form of fibers are of great practical and fundamental importance. Combination of a high specific area, flexibility, and superior directional strength make nanofiber a preferred material for many fields such as biomedical applications including drug delivery as well as scaffold formation. Manganese doped Zinc Sulphide with capping agent L-citrulline is blended with high molecular weight Poly Vinyl Alcohol (PVA) and the resulting solution is electro-spun to get non-woven nanofibers. Structural Characterization has been done by X-ray diffraction (XRD) and Fourier Transform Infra-Red Spectroscopy (FTIR). The fiber obtained is of good crystallinity as evidenced by the intense XRD peaks. The morphology is analyzed using a Scanning Electron Micrograph (SEM). The SEM micrographs reveal smooth fibers with several millimeters in length and average diameters in the range of 645 nm. Studies point to the possibility of using the prepared fibers for bio-medical applications.</p>M S ArchanaS JayalekshmiS DeepaNandakumar Kalarikkal

https://jasetm.fisat.ac.in/index.php/jasetm/article/view/37
<p><strong>Graphitic Carbon Nitride (g-C<sub>3</sub>N<sub>4</sub>) is a polymeric semiconductor with a bandgap of 2.7eV, enabling it to absorb visible light. In this paper, g-C<sub>3</sub>N<sub>4</sub> was synthesized by heating urea and thiourea separately for 2 hours at 550<sup>0</sup>C in a muffle furnace. The resulting products were named g-C3N4-U and g-C<sub>3</sub>N<sub>4</sub>-T, and investigated in terms of their crystal structure, morphology, and optical properties using X-Ray Diffractometer (XRD), Field Emission Scanning Electron Microscope (FESEM), UV-visible spectrophotometer, and Photoluminescence spectrometer. Brunauer-Emmett-Teller (BET) measurements were carried out to further observe the surface area, pore size, and pore volume of the as-prepared samples. The photocatalytic activity of the samples was investigated for pollution removal purposes, and its performance was examined under direct sunlight. The results showed that the urea-derived g-C<sub>3</sub>N<sub>4</sub> exhibited better photocatalytic activity, with complete degradation of the target pollutant within 90 minutes. </strong></p>J JassiS DeepaMariyam B Tharian
