Abstract

The rGO/Fe3O4 composite is one type of composites that can be used as a biosensor material, especially glucose sensors. The main ingredients of the composite synthesis are graphite and iron sand. The synthesis process of Fe3O4 was done using the coprecipitation method, while the graphite oxidation process was accomplished using the modified Hummer's method. The composites were formed using the ex-situ wet mixing method. The formed iron sand and graphite were characterized using FTIR and XRD, and it was found that Fe3O4 was formed from the appearance of the Fe-O bond, the oxidation process of graphite was seen from the appearance of the C=O bond, and the detection of Fe peaks corresponded to the cubic crystal plane. Likewise, the composites formed were also characterized using FTIR and XRD for identification of the rGO/Fe3O4 composite formation. It was proven from the presence of Fe-O and C-O bonds and the appearance of an amorphous peak of rGO in the XRD results. The performance of the  rGO/Fe3O4 composites as the glucose biosensor was examined by varying the mass of Fe3O4 on the composite, using UV-Vis spectroscopy. The performance of the rGO/Fe3O4 composite biosensor in absorbing glucose reached optimum at a mass variation of 0.3 grams of Fe3O4, as demonstrated by by the lowest absorbance peak with an intensity of 0.0048 at a wavelength of 440 nm, corresponding to glucose entrappment of 7.1 mg/gram.

Abstract

This paper reports ZnPt bimetallic nanoparticles (ZnPtBNs) synthesis through the liquid phase deposition (LPD) of of Zn(NO3)2.6H2O onto the indium-titanium oxide (ITO) substrates at various concentrations. The Effects of growth solution, the morphology, structural, and sheet resistance were studied. After preparation, the materials were characterized by using field emission electron microscopy (FESEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD) and Four Point Probe (FPP) measurement by using Keithley 2401 source-meter. By inserting a growth solution into the ITO substrate the ZnPtBNs was successfully in-situ prepared. The synthesized ZnPtBNs exhibited homogeneous, fibrous at the (111) orientation with an average diameter of 100-700 nm. The atomic ratio of Zn:Pt and sheet resistance of ZnPtBNs decreased with the increase of Zn(NO3)2.6H2O concentration. The optimal elemental composition of the sample was at a ratio of Zn:Pt (1:25) obtained at 0.467 mM of Zn(NO3)2.6H2O. It showed the smallest sheet resistance (13.41 ?) which was 38% lower than the ITO sheet resistance (18.44 ?).

Abstract

The potential of thin layer in many applications has led to research on the development of many new materials and their fabrication methods. This study aimed to synthesize a thin layer of ZnO using the facile and low-cost sol-gel spin coating method. The ZnO thin layer is deposited on a glass substrate and analyzed to observe the influence of the deposition variables such as heating and rotation speed, and its aging. The characterization methods include the identification of the formed phase using X-Ray Diffractometer (XRD), and the microstructure and elemental composition using Scanning Electron Microscopy (SEM) coupled with EDS (Energy Dispersive Spectrometer). The study shows that a thin layer of ZnO is successfully deposited on a glass substrate by heat treatment at temperatures of 300 oC and 500 oC. Furthermore, XRD reveals that higher heating temperatures result in higher diffraction peak intensity. At a heating temperature of 300 °C crystals are formed but are not yet perfectly oriented, while they are at 500 °C. On the other hand, higher spin coating rotation speed gives rise to lower intensity of diffraction peak. The ZnO crystallization is easier to form in the coating process with a lower rotation (1500 rpm). Interestingly, the thin layer is stable over time where there is no significant change in each sample, both in terms of intensity and width of the ZnO crystal peak. The results indicate that gel precursor aged less than two days can form ZnO crystals. Finally, SEM results show that the surface morphology of the ZnO layer heated at 500 oC has an average grain size of 300 nm. Based on the cross-sectional results of SEM shows that the higher the coating rotation speed has resulted the thinner of the ZnO layer, where the thickness of the resulting layer is on order >5 mm.

Abstract

During crude oil and natural gas extraction from a reservoir, a large amount of water is also produced. The water fraction contains oil, grease, organic and inorganic constituents, called produced water (PW). Over the years, efficient treatment of PW has been concerned. PW has been treated with various technologies, namely floatation, filtration, coagulation/flocculation, or biological processes. Those technologies were assembled to achieve discharge standards while minimizing the cost. Exploration of membrane-based technologies for the treatment of PW has recently been reported, including the emerging forward osmosis (FO) process. This paper reviews the research progress on the FO process for PW treatment. A brief introduction to the traditional treatment technologies is first provided. Next, the basics of the FO process and research progress on the application of FO on PW treatment are discussed. Finally, techniques for fouling control in FO are reviewed, namely osmotic backwashing, ultrasound, chemical cleaning, and air sparging.

Abstract

Countless research has been published on the impact of covid-19 on improvements in teaching techniques, activities, and motivational beliefs. Most research refers to a human's response before learning without testing students' comprehension and literacy linked to covid-19. This study adopted a qualitative approach, with a questionnaire serving as the primary research tool. Alternatively, the current study looks into students' cognitive and portrays their mental model of COVID-19. At the Islamic University of Lamongan, 30 students from the science education department and 30 students from the environmental health department took part. Students are chosen as transformational leaders and liaisons between society's academic and social environments. The researchers gather data based on an open-ended assessment that evaluates the concepts, causation, methods, and strategies that must be implemented to prevent the transmission of COVID-19. Participants completed questionnaires prepared for educational purposes before and after learning. Inductive and iterative investigation of the descriptions of students' answers revealed cognitive outcomes and mental models. Each questionnaire form is then checked for validity using the SPSS v24 program. The authenticity of the questionnaire responses for each questionnaire > rcount (N = 60), indicating that each question is valid, whereas the reliability test using Cronbach's Alpha provides a score of 0.78 > 0.60, indicating that the questionnaire employed is trustworthy. Regarding educational, cognitive processes, the analysis shows that some colleagues believe that COVID-19 is a conspiracy, while others need to add sufficient scientific literacy to validate that COVID-19 is a disease. Even after learning, they can only make general ways to mitigate the propagation of COVID-19. The findings for student mental models revealed considerable changes in clarity and coherence, such as models at levels 1 through 5 with the highest student mental models. This study culminates with the implication that students require scientific literacy to effectively communicate about COVID-19 and check out false information in public.

Abstract

Accounting education is crucial because it establishes the core knowledge required for education and growth in any country. During COVID-19, teachers in Accounting schools, like those in other educational institutions, were expected to adopt virtual classroom to continue their educational activities. This study aimed to demonstrate the virtual classroom readiness of Accounting school teachers in South Africa during the Covid-19 pandemic. The study employed qualitative research methods in this study, and the case study research design was used to explore the reality about virtual classroom readiness of Accounting school teachers and semi-structured interviews and thematic content analysis were employed to generate data. Results show that teachers are not prepared to implement virtual classroom during the Covid-19, according to the findings, and no one is assisting them. Another result indicated that virtual classroom facilities are lacking in schools. Education officials should offer ongoing virtual classroom courses for teachers, according to the study. In this study author concludes that, in order for instructors to be prepared for virtual classroom, educational administrators must oversee its implementation. In this study the author recommends that teachers must notify people in charge of education about what needs to be done in order to provide high-quality instruction.

Abstract

Introducing Information Communication Technology (ICT) resources and skills to Social Studies as instructional materials and aids can provide an accessible and flexible Social Studies education at the primary and secondary school levels in Delta State. Hence the aims of this study were to consider various ICT resources that can be harnessed and used by Social Studies teachers for social studies instructions; outline the benefits of ICT to students and teachers of Social Studies and identify the challenges affecting its usage for Social Studies instructions in Delta State. The study employed the survey research design, a sample of sixty (60) Social Studies teachers from six primaries and six Junior Secondary Schools selected randomly from six Local Government Areas of the state. The main instrument for data collection was a well- structured questionnaire designed to obtain data and centered around the main objectives of the study. Sixty (60) copies of the questionnaire were distributed and sixty (60) copies were retrieved and used for data analysis. While data gathered were analyzed using statistical tools of mean and percentages. The result revealed that ICT resources and skills such as android phones, internet browsing, power point projection, virtual learning and computers assist in teaching Social Studies concepts. Secondly, the study revealed that ICT skills and facilities contribute meaningfully to Social Studies instructions when used by teachers, students will derive holistic knowledge when taught with ICT tools. Meanwhile the findings showed that there exist many setbacks and challenges in ICT usage such as funding, capacity building and lack of electricity supply amongst others. Based on these findings, one of the recommendations made was that stakeholders in the education sector both government and private organizations, should be concerned with the provision of ICT facilities in primary and junior secondary schools across Delta State.
