Analysis of Thermoelectric Generator for Automotive Exhaust Energy Recovery
Abstract: Utilizing waste heat from thermodynamic systems has shown to be a successful tactic for reducing environmental emissions and improving overall energy efficiency. About 40% of the chemical energy generated during fuel combustion is rejected by exhaust gases in internal combustion engines. It is possible to increase vehicle fuel efficiency and lower greenhouse gas emissions by harvesting this otherwise lost heat energy and turning it into useable electrical power. A viable …

In-Situ Polymerized GO/PANI Composites: Structural Evolution, Optical Modulation, and NH₃ Sensing at Room Temperature
Abstract: Graphene oxide (GO)/polyaniline (PANI) composites with varying PANI contents (20, 40, and 60 wt%) were synthesized via in-situ oxidative polymerization and systematically investigated for their structural, morphological, optical, and gas-sensing properties. X-ray diffraction (XRD) confirmed a progressive increase in interlayer spacing and partial exfoliation of GO layers with increasing PANI content, indicating intercalation-assisted hybridization. Fourier transform infrared (FTIR) spectroscopy revealed the characteristic vibrational bands of both constituents and confirmed strong …

Solid-State Reactions: Mechanistic Insights, Kinetic Behavior and Emerging Applications in Advanced Materials
Abstract: Solid-state reactions are fundamental to the synthesis and transformation of inorganic materials, playing a crucial role in the development of ceramics, semiconductors, catalysts, and energy storage systems. Unlike reactions in liquid or gaseous phases, they are limited by restricted atomic mobility and typically require elevated temperatures to enhance diffusion and overcome activation energy barriers. These reactions proceed through interfacial contact between solid reactants, followed by nucleation of product phases and …

Structural, Optical, Surface and Gas-Sensing Properties of rGO/Sn1-xZnxO₂ Nanocomposites
Abstract: rGO/Sn₁₋ₓZnₓO₂ nanocomposites with x = 0.00–0.75 were synthesized by sol–gel auto-combustion followed by wet impregnation with reduced graphene oxide. The adopted synthesis route enabled homogeneous Zn incorporation into the SnO₂ matrix and uniform distribution of rGO, leading to improved structural integrity and interfacial contact between the two components. XRD confirmed a dominant tetragonal cassiterite SnO₂ structure, while FTIR, FESEM, EDS, UV–visible, and BET analyses verified oxide–rGO coupling, Zn-dependent structural modification, …
