Sustainability of nanomanufacturing has triggered tremendous research interest in recent years, especially the energy consumption and environmental impacts of nanomaterial. TiO2 nanotube is a typical material with broad application potential. In this paper a thermodynamic analysis model integrating the energy consumption and exergy losses is presented for sustainability improvement of TiO2 nanotube synthesis process. This thermodynamic model was validated by the TiO2 nanotube electrochemical anodization process. Comparisons of energy consumption, exergy losses and environmental impacts of five main stages showed the effective sustainability improvement potential. This work can be extended to sustainability improvement of other similar nanomaterial synthesis processes.

Energy consumption is a purely thermodynamic concept very useful in several scientific fields such as desalination, oceanography, biology, geochemistry and environmental processes, as well as in industrial applications. In this investigation, based on a thermodynamic approach, the calculation of energy consumption was evaluated during the desalination of seawater simulated to the aqueous ternary system {NaCl + KCl}(aq). The mixing ionic parameters, obtained in our previous work, are used to predict the osmotic and activity coefficients in the aqueous solutions at different salinities ranging from 3.6 up to 72 g.L-1 at T = 298.15 K using the ion interaction model. The theoretical energy consumption of desalination was calculated at various salinities and recovery ratios.

In this work, we investigate the effect actuator position on the theoretical energy consumption of an electrically powered bipedal robot. Specifically, considerable gains are possible through the optimization of the actuator placement relative to joints and their axes, in particular biarticular actuators, are proposed. The energy losses of electric actuators on the two most powerful and inefficient joints of a biped, the hip and the knee, are considered. In standing or walking tasks of a biped’s legs within mathematical model, furthermore, imposing constraints on the actuator placement is used in a genetic algorithm to find the optimum configuration of various biarticular configurations.

Theoretical Energy Consumption

Thermodynamic analysis method for iron and steel manufacturing system is developed to describe the energy flow. The theoretical energy consumption for the manufacturing process is proposed to analyze the energy-saving potential. Energy balance based on enthalpy with a uniform reference state is established to analyze the amounts and forms of energy flow in the manufacturing system. The energy-saving potential of blast furnace system is discussed to choose the appropriate energy-saving methods and technologies.
