Innovative methods to fabricate and integrate biodegradable high-grade electronics on green substrates are needed for the next generation of robust high-performance transient electronics. This is also alleviate growing problem electronic waste (e-waste). Herein, authors present n-channel silicon (Si) nanoribbons-based transistors developed metal (magnesium) foils using direct transfer printing ...

the hydrodynamic behavior of approaching flow and the amount of sediment entry into right-angled lateral intakes in diversion dams were investigated using a laboratory channel by experimental measurement and observation. the velocity field upstream of the intake in the main channel and before it at the sluice gate was measured at different elevations of flow at different discharge rates of the ...

background and purpose: due to the lack of accurate statistics on the amount of waste generated in the energy production sector in zahedan, before any planning, one should identify all waste producing centers associated with the energy sector and also the quantity and quality of their waste in zahedan. materials and methods: this research is a cross-sectional descriptive study. it examined the ...

hospital wastes are one of most important environmental problems because of their hazardous, toxic and pathogenic characteristics. the aims of this study were to identify and measure the amount of hospital wastes and classify of them according to who criteria in amirolmomenin(as) hospital and shahid rajaei policlinic in ahwaz, sw of iran. this research was a field-descriptive study. initially, ...

The current energy and environmental crisis, linked to increasing industrialisation, has progressively driven the adoption of solutions focused on circular life cycle thinking, such as waste management with resource recovery decarbonization technologies. In this context, study was built quantify performance a two-stage wastewater treatment process (dark fermentation anaerobic digestion) in whic...

Quantum-dot cellular automata (QCA) nanotechnology is a practical suggestion for replacing present silicon-based technologies. It provides many benefits, such as low power usage, high velocity, and an extreme density of logic functions on chip. In contrast, designing circuits with no waste information (reversible circuits) may further reduce energy losses. The Feynman gate has been recognized o...

Abstract The objective of this study was to analyse the life cycle coconut oil industry and process improvement alternatives. analysis (LCA) method are based on scope gate gate. This shows that input for production consists copra as main raw material several supporting materials energy. outputs oil, pulp pellets, waste (liquid, solid, gas). total potential GHG emissions, acidification, eutrophi...

Quantum-dot Cellular Automata (QCA) technology is attractive due to its low power consumption, fast speed and small dimension, therefore, it is a promising alternative to CMOS technology. In QCA, configuration of charges plays the role which is played by current in CMOS. This replacement provides the significant advantages. Additionally, exclusive-or (XOR) gate is a useful building block in man...
