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, …

Experimental, Analytical and Numerical Study of Energy Absorption Properties of Aluminum Crush Boxes with and without Buckling Initiators (Axial Loading)
Abstract: The crashworthiness in automobile is stated as the capability of a passenger car and its interior arrangements to safe-guard occupants from harm. Whenever an accident occurs, the passengers in the car can be injured due to one of the following reasons: (1) excess acceleration force; (2) physical injury from contact with injurious surfaces, and; (3) exposed to fire, smoke, and chemicals released during accidents. Thus effective crashworthiness design must take …
