Nanostructure-Induced Thermoelectric Enhancement in Bi₂Te₃ Nanorods Design, Analysis, and Performance Evaluation
Abstract: Thermoelectric materials capable of efficient energy conversion near room temperature are critical for waste heat recovery applications. In this work, solution-grown Bi₂Te₃ nanorods were synthesized via a trioctylphosphine-assisted thermal decomposition route, and the influence of surfactant-induced nanostructuring on their thermoelectric properties was systematically investigated. Structural analysis using X-ray diffraction and Rietveld refinement confirmed the formation of rhombohedral Bi₂Te₃ with the emergence of Bi₂Te₃–BiTe nanocomposites at higher surfactant concentrations. Electron microscopy …

Analysis of shading and energy generation by PV overhang using different models
Abstract: This paper presents the shading and energy generated by photovoltaic integrated overhangs in a building. The air temperature is greatly raised by sunlight entering through glass facades and windows that are not shaded. The overhang decreases the sunlit area of the windows thus decreasing the inside room temperature which decreases the requirement of cooling the rooms. The energy production by the photovoltaic modules has been calculated using three popular energy …

Study on GP Zones Formation in the Sc Inoculated Ternary Al-Zn-Mg Alloys
Abstract: Mostly, ternary Al-Zn-Mg (7075) alloys are used in automotive and aerospace engineering due to readily age-hardening response and high specific strength-to-density ratio. Scandium (Sc) has great inoculation effect in Al-Zn-Mg alloys. The cast Al-Zn-Mg alloys system undergoes a complex transition sequence in order to gain maximum strength. This sequence consists of solutionizing then immediate quenching in water (T4), natural ageing and artificial ageing (T6); usually, in several temperature steps to …
