The results demonstrate that the incorporation of boron–containing industrial waste achieves the lowest recorded oxidation index (27.5 %), with minimal impact from temperature fluctuations on its oxidation resistance. The synergistic interactions among TiB<sub>2</sub>, BN, and AlN facilitate the formation of a dense protective layer, effectively preventing oxygen infiltration and reducing reactive interactions with the base material. This improvement is attributed primarily to the formation of specific phases such as Mg<sub>3</sub>B<sub>2</sub>O<sub>6</sub>, Mg<sub>2</sub>TiO<sub>4</sub>, and Mg<sub>2</sub>SiO<sub>4</sub>, which collectively enhance the material’s density and oxidation resistance. The incorporation of boron–containing industrial waste into MgO–C refractories not only greatly improves their oxidation resistance but also offers an innovative solution for industrial waste recycling. This approach underscores its considerable potential for economic benefits and improved sustainability.

Conventional CO<sub>2</sub> capture relies on temperature swing adsorption (TSA) and pressure swing adsorption (PSA) to achieve desorption.

To overcome these obstacles, emerging non-conventional techniques incorporate electromagnetic, acoustic, photochemical, or electrochemical stimuli to enhance efficiency, extend sorbent lifespan, and improve product purity. Innovative approaches, such as microwave swing adsorption (MSA), magnetic induction swing adsorption (MISA), electric swing adsorption (ESA), ultrasound swing adsorption (USSA), and light induction swing adsorption (LISA), deliver localised energy-efficient regeneration. Similarly, pH swing adsorption (pHSA) exploits electrochemical gradients to release CO<sub>2</sub> with minimal thermal input. When coupled with sorbents like activated carbons, zeolites, metal-organic frameworks (MOFs), and amine-based solutions, these methods can lower thermal penalties and yield cleaner, more economical CO₂ capture. Although these techniques have not yet achieved broad commercial deployment, laboratory and pilot-scale research demonstrates their potential for reduced energy requirements and improved sorbent stability.
