Aluminium is a widely used metal and one of the most energy intensive industries, and therefore it has been included in most energy models and scenarios. Material demand and supply are broadly linked to energy, water, and climate change. In this study, we develop four global and regional process based scenarios for the material-energy-water nexus combined with CO emissions and applied to aluminium. The scenarios used in this study are; Market World (MW), Toward Resilience (TR), Security Foremost (SF), and Equitability World (EW). The results indicate that global CO emissions are expected to increase as a result of increasing aluminium demand, although aluminium secondary supply, energy efficiency, and cleaner energy supply technologies are expected to increase in the next 30 years. Policy and sustainability (TR and EW) scenarios are ultimately the best in terms of global climate change since the two scenarios have the lowest CO emissions, although they also have the highest aluminium demand and energy. It is therefore necessary to implement cleaner energy supply and energy efficiency technologies at high rates in aluminium industry to mitigate possible increase in CO emissions.

The adhesion between metals and polymers plays a pivotal role in numerous industrial applications, especially within the automotive and aerospace sectors, where there is a growing demand for materials that are both lightweight and durable. This study introduces an innovative technique to improve the adhesion between a metal and a polymer in hybrid structures through the synergistic use of anodization and plasma treatment. By forming a nanoporous oxide layer on aluminum surfaces, anodization enhances the interface for polymer binding.

Water contamination greatly impacts human health. The Metropolitan Area of the Valley of Mexico (MAVM) is one of the most densely inhabited and polluted places globally, with a significant problem being the rising water demand. The research aims to assess the impact of metals such as iron, aluminum, lead, cadmium, and total chromium, among others, in the water of the Madin Dam, a key reservoir in the area's water supply.

To prevent water scarcity, wastewater must be discharged to the surface or groundwater after being treated. Another method is to reuse wastewater in some areas after treatment and evaluate it as much as possible. In this study, it is aimed to recover and reuse the caustic (sodium hydroxide, NaOH) used in the recycling of plastic bottles from polyethylene terephthalate (PET) washing wastewater.

A series of novel chain-extended polyurethanes (CEPUs) featuring degradable sulfonyl ethyl urethane chain-extenders that permit degradation under base-triggered conditions to afford "debond-on-demand" elastomeric adhesives are reported. Exposure of the CEPUs to -butylammonium fluoride (TBAF) triggered the degradation of the sulfonyl ethyl urethane chain-extenders. Lap shear adhesion tests of the CEPUs exposed to TBAF revealed reductions in shear strength of up to 65% for both aluminum and glass substrates, from 2.

Quantum technology exploits fragile quantum electronic phenomena whose energy scales demand ultra-low electron temperature operation. The lack of electron-phonon coupling at cryogenic temperatures makes cooling the electrons down to a few tens of millikelvin a non-trivial task, requiring extensive efforts on thermalization and filtering high-frequency noise. Existing techniques employ bulky and heavy cryogenic metal-powder filters, which prove ineffective at sub-GHz frequency regimes and unsuitable for high-density quantum circuits such as spin qubits.
