Before that, graphene oxide (GO) was prepared using a modified version of Hummer's process. The crystallinity and phase have been verified with an XRD device. Morphological analysis using FESEM images confirms the porous nature. Conversely, comparisons of their UV-vis have been done to help determine the band gaps between GO and rGO. In this project, electrical (resistive) biosensor for glucose monitoring has been experienced. A comparison study of different layers, enzymatic interaction and their out has been carried for the rGO based devices. Here, alpha- glucose has been tested with the biosensor. After a layer-dependent experiment, it can be expressed from the I-V analysis 1layer rGO device has shown a better response than GOx+rGO-coated all devices.1L rGO-coated device also gives better response than 1L GOx+rGO and from LOD curve it can be clearly stated that 1 layer rGO coated device has better sensibility in all aspect. 2024-01-01T00:00:00Z https://irju.jdvu.ac.in/jspui/handle/123456789/10777 Title: Study of release kinetics of kulekhara (herbal drug) from transdermal patch to control anaemia disease Authors: Paine, Aloke 2024-01-01T00:00:00Z https://irju.jdvu.ac.in/jspui/handle/123456789/10776 Title: Study of droplet impact on flexible surface Authors: Das, Ayas Kumar 2024-01-01T00:00:00Z https://irju.jdvu.ac.in/jspui/handle/123456789/10775 Title: Voltage dependent differentially grown zinc oxide nanowire based three terminal device for water quality monitoring Authors: Kazi Wakar Hasan Abstract: It is necessary to detect Heavy Metal Ions due to their toxic effects on the environment and human health. Chromium(VI), Copper(II), Iron(II) and Nickel(III) ions pose serious risks when present in above par concentrations in water sources, by contaminating drinking water supplies, accumulating in ecosystems and have toxic effects on aquatic life. Development of reliable and sensitive sensing devices for their detection is crucial for effective monitoring, ensuring water safety and implementing appropriate remediation strategies. This thesis focuses on the detection and analysis of specific heavy metal ions, namely Chromium(VI), Copper(II), Iron(II) and Nickel(III) ions in water samples. The material of choice for this study is Zinc Oxide, which exhibits favourable properties for sensing applications. The Zinc Oxide Nanowire based Three Terminal Devices are prepared under different Bias Voltages and their further characterization and heavy metal ion sensing is done. The synthesized materials were characterized using X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM) and Diffuse Reflectance Spectroscopy (DRS). The results of the sensing experiments demonstrated that the Zinc Oxide-based Three Terminal Device has better response towards Chromium(VI), Copper(II), Nickel(III) ions but not towards Iron(II) ions. 2024-01-01T00:00:00Z
