“…In analytical chemistry, geopolymers are a potential stationary phase for liquid chromatography due to their different selectivity compared with existing phases and stability at different pH conditions. [139][140][141] Finally, there are also several proposed applications utilizing the electrical properties of geopolymers or AAMs: electrode materials for structural supercapacitors 142 and microbial fuel cells, 143 solid-state battery electrolytes, 144 and dielectric materials for antennas. 145 In many of the mentioned technical applications, beyond construction materials for which parts of simple shapes are required, components of intricate or complex shapes are usually necessary.…”

This perspective article delves into the transformative potential of alkali‐activated materials, acid‐activated materials, and geopolymers in mitigating climate change and market challenges. To harness the benefits of these materials, a comprehensive strategy is proposed. This strategy aims to integrate these materials into existing construction regulations, facilitate certification, and promote market access. Emphasizing research and innovation, the article advocates for, increased funding to refine the chemistry and production of these materials, prioritizing low‐cost alternatives and local waste materials. Collaboration between academia and industry is encouraged to expedite technological advances and broaden applications. This article also underscores the need to develop economic and business models emphasizing the long‐term benefits of these materials, including lower life‐cycle costs and reduced environmental impact. Incentivizing adoption through financial mechanisms like tax credits and subsidies is suggested. The strategy also includes scaling up production technology, fostering industrial collaboration for commercial viability, and developing global supply chains. Educational programs for professionals and regulators are recommended to enhance awareness and adoption. Additionally, comprehensive life‐cycle assessments are proposed to demonstrate environmental benefits. The strategy culminates in expanding the applications of these materials beyond construction, fostering international collaboration for knowledge sharing, and thus positioning these materials as essential for sustainable construction and climate change mitigation.

“…For example, the sulfonate/tertiary amine and sulfonate/pyridinium phases (Table 2) were developed as the mixed‐mode phases (Bo et al, 2017; Takafuji, Shahruzzaman, Sarahara, & Ihara, 2018) but were evaluated only under HILIC conditions. Armstrong and coworkers synthesized an aluminosilicate‐based geopolymer material as the stationary phase for HILIC (Thakur et al, 2019). The aluminosilicate material is capable of cation‐exchange process and exhibits similar ion‐exchange selectivity to silica and diol phases.…”

Various polar stationary phases are available for hydrophilic interaction chromatography (HILIC) and help drive continuous applications in biomedical, environmental, and pharmaceutical areas in the past decade. Although the stationary phases for HILIC have been reviewed previously, it is an appropriate time to take another look at the progresses made during the past 5 years. The current review provides an overview of the polar stationary phases commercially available for HILIC applications in an effort to assist scientists in selecting suitable columns. New types of stationary phases that were published in literature in the past 5 years are summarized and discussed. The trend in stationary phase research and development is also highlighted. Of particular interest is the experimental evidence for direct interactions of polar analytes with the ligands of the stationary phases under HILIC conditions. In addition, two different approaches have been developed to delineate the relative significance of the partitioning and adsorption mechanisms in HILIC, representing an important advancement in our understanding of the retention mechanisms in HILIC.

“…The Armstrong research group investigated geopolymers as a new class of high pH stable chromatographic supports, which were previously introduced in the field of chromatography by Alzeer et al − These amorphous polycondensed aluminosilicate ceramic solids have a high mechanical strength, chemical stability in basic conditions, and are water insoluble, making them a unique solid support material that can be turned into porous spherical particles with high surface area amenable for chromatographic purposes . Their chromatographic selectivity shows a strong hydrophilic and electrostatic character, and in the HILIC mode a different selectivity than that in silica columns is found, with excellent peak shapes.…”
