Repercussion of Swift Heavy Ion (SHI) irradiation on nickel-based nanorods of Metal-Organic Framework (NRs-Ni3HHTP2-MOF) for enhancement in the properties of ChemFET based gas sensor has been investigated. Nanorods of Ni3HHTP2-MOF were synthesized by chemical method and exposed to C 12+ ions irradiation with fluence 1x10 11 ion/cm 2 and 1x10 12 ion/cm 2 . The structural, spectroscopic morphological and optical characterizations were carried out using x-ray diffraction (XRD), fourier transfer infrared spectroscopy (FTIR), atomic force microscopy (AFM) with scanning electron microscopy (SEM) and UV-visible spectroscopy were studied respectively. Whereas the bandgap was calculated from Tauc's plot. The synthesized nanorods of Ni3HHTP2 MOF were drop-casted on gold coated microelectrodes on silicon/silicon dioxide (Si/SiO2) substrate, where silicon layer serves as a gate and gold microelectrodes on silicon/silicon dioxide (Si/SiO2) substrate as a source and drain. The transmutations in material properties due to SHI irradiations were serviceable for enhancing field-effect transistor (transfer and output) properties.

In the present work, we have prepared polymer blend of polyvinyl butyral (PVB) and poly (3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT: PSS) by solution casting route. Blends were tested for various structural, morphological, and electrochemical techniques. Structural properties were investigated by XRD technique exploring the contribution conducting polymer in host system PVB exhibit amorphous nature. COO functional group contributed in blend configuration was confirmed by FTIR technique. Clustering of PEDOT:PSS in blend system were observed by scanning electron microscopy.Subatomic surface topology and increased roughness due to blending concentration of conducting polymer were analyzed by probe microscopy techniques.Increased softness of blends was confirmed by shore "A" durometer test. PVB/PEDOT:PSS blend was drop casted on glassy carbon electrode and employed for detection of various metal ions. It was deployed for electrochemical sensing of Cu 2+ ion. Electrochemical sensing investigation was done by differential pulse voltammetry technique. Performance of blends at 4.5 pH, 200 s deposition time and À1.2 V deposition potential was more accurate and sensitive toward detection of Cu 2+ ion. The developed electrochemical sensor exhibited rapid sensing response in the range of 1.6 to 8.3 μM. Furthermor,e an influence of many analytical parameters such as pH, deposition time and deposition potential on Cu 2+ ion investigation were disclosed. This investigation may be feasible to construct a very simple, fast, and efficient electrochemical sensing system for toxic heavy metals at low-level concentration.
