Spatiotemporal mapping of Land Use/Land Cover dynamics using Remote Sensing and GIS approach: a case study of Prayagraj City, India (1988–2018)

Abstract: Prayagraj City is one the biggest cities in the State of Uttar Pradesh which has been selected as Smart City by Ministry of Housing and Urban Affairs, Government of India, in 2015. This city has rapidly evolved in the last three decades due to the urbanization process. This study has used multispectral imageries of Landsat Thematic Mapper and Operational Land Imager/Thermal Infrared Sensor of four different time points at the interval of ~ 10 years, i.e., 1988, 1997, 2008, and 2018. These images have been preprocessed and then classified through supervised classification using Maximum Likelihood Classifier in ERDAS IMAGINE version 2014. The overall accuracy achieved is more than 88% in all the four time points. The periodical change results have revealed that all land use/land cover (LU/LC) classes has altered in all periods, i.e., 1988–1997, 1997–2008, 2008–2018, and 1988–2018 with remarkable trends, patterns, and magnitudes. The growth of Built-up land is a major concern. The results of the change matrix (1988–2018) have indicated that the most expanded class was built-up land which has evolved into 64.52% at the cost of Agriculture land by 24.41%, Forest land by 10.56%, and Barren land by 6.01%. The above results of LU/LC dynamics can help in making planning and policy development for restoring and enhancing the carrying capacity of land and sustainability of the environment in a city landscape.

Sensitive detection using heterostructure of black phosphorus, transition metal di-chalcogenides and MXene in SPR sensor

Abstract: This work presents van der Waals heterostructure (vdWh) of Black phosphorus (BP)/Transition metal di-chalcogenides (TMDs)/MXene (Ti3C2Tx) based highly sensitive novel SPR sensor for biochemical sensing. 2D layered nature of BP, TMDs, and MXene allow them to form van der Waals heterostructure by vertically stacking them together to get exotic electronic and optical properties useful for surface plasmon resonance (SPR) sensing. Unique properties of MXene like its layered architecture, larger surface area, highly accessible hydrophilic surface terminations, chemical stability, smaller work function, and strong light-matter interaction are utilized to enhance the sensitivity of the proposed sensor. The proposed work theoretically analyzes its sensitivity (S) and compares it with other structures. The anisotropic nature of 2D layered BP is used to tune the sensitivity of the proposed sensor. The highest sensitivity of 388ο/RIU is achieved at 633 nm wavelength for WS2 tri-layer in the proposed biochemical sensor. The SPs field variation along normal to interface validates the highest sensitivity obtained for the proposed heterostructure SPR sensor through field plots. These results will open an innovative route to design and develop such an SPR biochemical sensor practically, with fabrication possibilities of MXene with TMDs and BP.
