  • SPATIO-TEMPORAL TRENDS OF GREEN INFRASTRUCTURE DEVELOPMENT IN IBADAN, NIGERIA


OLADIRAN, Ibiyinka Olaide and OLOUKOI, Grace

Abstract:
Green Infrastructure (GI) has become increasingly recognized as an important component of sustainable urban development in recent years. However, in many cities worldwide, the development of GI is inadequate and fragmented, leading to environmental degradation and reduced quality of life for urban residents. This study aims to investigate the spatio-temporal trends of GI development in Ibadan, Nigeria, using satellite imagery from 2000, 2013, and 2020. The study maps analyzes the distribution and trends of GI in Ibadan, including its current status and spatial distribution. The findings suggest that Ibadan's GI is limited and fragmented, with a few green spaces scattered throughout the city. The study identifies the driving factors influencing GI development in Ibadan, including rapid urbanization, land-use change, and inadequate urban planning. The study also provides an insight into the future trajectory of GI development in Ibadan and recommends the need for comprehensive urban planning strategies to promote sustainable urban development and enhance the quality of life for Ibadan's residents. The study's findings can provide valuable insights for policymakers, planners, and other stakeholders in developing strategies that prioritize the development of GI in Ibadan and similar cities in the region.

  • A STUDY ON STANNATE NANO STRUCTURES AND THEIR CHARACTERIZATION & SYNTHESIS


Dr Prashant Dwivedi

Abstract:
The unusual properties and wide range of possible applications of stannate nanostructures—nanostructures composed of tin (Sn) and oxygen (O)—have garnered considerable interest in these materials. Using a wide range of experimental techniques, this study investigates both the synthesis and characterization of stannate nanostructures. To manipulate the nanostructures' size, shape, and crystalline structure, researchers are looking into several synthesis methods. The solvothermal, hydrothermal, and template-assisted approaches fall under this category. The optical, electrical, and structural characteristics of the materials are studied using state-of-the-art characterization methods such as spectroscopic analysis, electron microscopy, and X-ray diffraction. In areas including gas sensing, photocatalysis, energy storage, and biomedical devices, the results give helpful suggestions for improving the functionality of stannate nanostructures. These results provide light on the connections between stannate nanostructure production, structure, and characteristics. This comprehensive study lays the groundwork for new synthesis methods and specific applications in many fields, and it significantly advances our basic knowledge of stannate nanostructures.

  • SIMULATION OF ENERGETICALLY BILAYER ORGANIC SOLAR CELLS


Yesh Desh

Abstract:
Organic solar cells (OSCs) have emerged as a promising alternative to traditional inorganic solar cells due to their lightweight, flexibility, and potential for lower-cost manufacturing. However, their performance lags behind their inorganic counterparts. To bridge this gap, researchers are employing computational simulations to understand and optimize the behavior of OSCs, particularly those with energetic disorder. Energetic disorder arises from the inherent variations in the energy levels of organic materials. Unlike the well-defined electronic structures of inorganic semiconductors, organic materials exhibit a distribution of energy states for both electrons (highest occupied molecular orbital, HOMO) and holes (lowest unoccupied molecular orbital, LUMO).

  • Fourier-Transform Infrared Spectroscopy (FTIR): Analysis of Normal and Galled Leaf of Mitragyna parvifolia


Dr. Om Prakash Meena

Abstract:
Infrared spectroscopy, or FTIR, involves subjecting a material to IR radiation. The sample absorbs some of the radiations and some radiations it transmits. The consequential indication is a spectrum at the detector which represents a molecular “fingerprint” of the sample.
