Special Issue Information

Dear Colleagues,

We cordially invite you to submit your research and/or review work to this Special Issue entitled “Recent Advances in the Sustainability of Energy- and Resource-Intensive Key Materials”.

In the near future, the global scenario regarding industrial production will need to manage several critical aspects to find a balance between the increase in demand for goods and the environmental impact of industrial production. Converging concerns are related to energy and resource demands, which are the basis of revisions to energy production policies, energy efficiency implementation, green chemistry processes and circular economy approaches. The challenge is even more difficult for several key materials (which the current infrastructure growth is grounded on) that are crucial for near-future developments and are currently impossible to substitute. For many of them, serious warnings regarding their use are related to the global feedstock distribution, availability, and use as well as energetic and environmental footprints. The needs to implement and improve processes for materials and elemental recovery, as well as recycling, are still lacking attention.

The scope of this issue is to give insights, from both academic and industrial points of view, on the state of the art for specifically critical materials, their current impacts and threats and their sustainable production processes, as well as to provide the most updated and promising advances on research results that can contribute to the reduction and mitigation of the main problems that a sustainable global future faces. The topics of interests include, but are not limited to, energy saving, circular economy, critical raw materials, feedstock, LCA, energy and resource intensity, environmental impacts, low-temperature clinkers, concrete demolition waste, supplementary cementitious materials, etc.

We are looking forward to receiving your excellent research works for this Special Issue.

Enhancing the heat transfer performance of heat exchangers is one of the main methods to reduce energy consumption and carbon emissions in heating, ventilation, air-conditioning and refrigeration (HVAC&R) systems. Wettability modified surfaces developed gradually may help. This study aims to improve the performance of heat exchangers from the perspective of component materials. The facile and cost-effective fabrication method of superhydrophobic Al-based finned-tube heat exchangers with acid etching and stearic acid self-assembly was proposed and optimized in this study, so that the modified Al fins could achieve stronger wettability and durability. The effect of process parameters on the wettability of the Al fins was by response surface methodology (RSM) and variance analysis. Then, the modified fins were characterized by field-emission scanning electron microscopy (FE-SEM), 3D topography profiler, X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared spectroscopy (FTIR), respectively. The durability of the superhydrophobic fins was investigated by air exposure, corrosion resistance, and mechanical robustness experiments. The RSM and variance analysis demonstrated that a water contact angle (WCA) of 166.9° can be obtained with the etching time in 2 mol/L HCl solution of 10.5 min, the self-assembly time in the stearic acid ethanol solution of 48 h, and drying under 73.0 °C. The surface morphology showed suitable micro-nano structures with a mean roughness (Ra) of 467.58 nm and a maximum peak-to-valley vertical distance (Rt) of 4.095 μm. The chemical component demonstrated the self-assembly of an alkyl chain. The WCAs declined slightly in durability experiments, which showed the feasibility of the superhydrophobic heat exchangers under actual conditions. Full article
