Mineral carbonation has been proposed as an option for carbon capture and utilisation in the construction sector, where it has been successfully demonstrated in the production of cementitious materials, concrete, and associated products. Synthetic magnesium carbonate trihydrate, nesquehonite, investigated in this article, develops cementitious properties via thermal processing, where the sample paste is heated and hardened inside a mould. Such material would incorporate around 30% of CO2 into its final composition, and near-maximum in terms of the current development of carbonate-bearing construction materials. Initially, the mechanism of strength development was thought to be linked to phase conversion (e.g., towards hydromagnesite). However, it has not yet been systematically investigated. Thus, this study provides statistically validated insights into some of the synthesis and processing factors that influence the resulting compressive strength of nesquehonite-based products. The results disclosed within suggest a more eco-efficient production technique and propose a working hypothesis on the relation between compressive strength and the nesquehonite—hydromagnesite conversion reaction.

Qatar’s ongoing national development has brought notable advances in education, infrastructure, and gender inclusion. However, Qatari women remain significantly underrepresented in leadership positions across business, academia, and government sectors. This article examines the multifaceted challenges that Qatari women face in achieving and maintaining leadership roles. Using a qualitative approach that involves surveys and in-depth interviews, the study uncovers institutional, cultural, and interpersonal barriers that hinder women’s progress, despite high levels of academic achievement and national policy commitments to gender equality. Drawing on first-person narratives, this article outlines systemic human resources obstacles, patriarchal expectations, the effect of wasta (personal connections), and the emotional toll of navigating traditional gender roles. It concludes with policy recommendations aimed at fostering sustainable gender equity, institutional transformation, and leadership inclusivity. The findings have broad relevance for policymakers, academic institutions, and civil society actors in Qatar and across all other Gulf Cooperation Council countries.
