Summary: Cor triatriatum sinister is a rare congenital heart disease characterized by an additional fibromuscular membrane in the left atrium. Cardioembolic stroke, a rare complication, was diagnosed in an 18-year-old female patient with nonrestrictive cor triatriatum sinister and patent foramen ovale. The importance of identifying congenital cardiac defects as potential substrates for cardioembolism in young patients was highlighted. A multidisciplinary approach is necessary to determine the optimal management strategy for patients with cor triatriatum sinister complicated by cardioembolic stroke.

Summary: The study investigates the association between morphological variation and postsurgical pulmonary vein stenosis in patients with cardiac total anomalous pulmonary venous connection. It finds that the number of inter-junction PV orifice and length of drainage route are correlated with an increased risk of PPVS in different connection types. Morphological subcategorization can assist in surgical decision-making.

Summary: This study aimed to evaluate the long-term risk of pulmonary vein reintervention and mortality in patients with HTX+. The results showed that HTX+ was associated with a higher rate of mortality and a greater number of pulmonary vein interventions, which may be related to the high prevalence of single ventricle physiology in this cohort.

Summary: The study investigated the influence of drying on the microstructure, physical and chemical properties of tropical wood species. Different species showed variations in pore volume, density, lignin content and thermal stability. Lightwoods displayed higher porosity and lower thermal stability compared to dense woods, indicating potential for ecological and sustainable wood transformation policies.

Summary: The study focuses on the synthesis of geopolymers from metakaolin and phosphoric acid with varying [P] concentration and the addition of water to improve the viscosity for complex shapes. Measurements of viscosity, density, and consolidation times, as well as studies on microstructure and mechanical properties were conducted to assess the influence of water content on the material's structure. The results showed that the addition of water led to the formation of new amorphous networks in the geopolymers, impacting their properties.

Summary: The study investigated the shrinkage of geopolymer materials, showing that alkaline solution plays a key role in controlling shrinkage. Additives were found to reduce shrinkage, with normalized sand having the highest impact. The increase of liquid to solid ratio was proven to correlate with the increase of shrinkage.

Summary: The study examines the impact of carbonate content on the thermal behavior of geopolymers by calcining various mixtures at different temperatures. By controlling the available alkaline earth cations, it is possible to predict the shrinkage of geopolymer materials during thermal treatment. Different calcium and magnesium silicates can be formed based on the composition of the mixtures, resulting in varying shrinkage values.

Summary: The study evaluated the structural evolution of geopolymer under different temperatures and times for nuclear waste disposal. Results showed changes in density and mechanical strength over time at both 20 and 90 degrees C, with stability in structure at 20 degrees C and nucleation of zeolite type phase at 90 degrees C. Mesoporosity increased over time, while higher temperatures led to increased porosity and pore size due to pore coalescence and water removal.

Summary: This study investigates the effects of adding silica fume on the densification and mechanical properties of geopolymers using the warm press method. The results show that adding an appropriate amount of silica fume can enhance the compressive strength of geopolymers, but an excessive amount can lead to a decrease in strength.

Summary: In this study, a novel cold reaction sintering method using a warm-pressing device was used to harden boron carbide (B4C) with an inorganic binder, namely a geopolymer binder. The research found that when appropriate pressure was applied to the raw materials, the geopolymer binder was completely geopolymerized and formed a strong hardened body. The compressive strength of the hardened body exceeded 50 MPa under certain conditions.

Summary: The valorization of local materials in public building construction in emerging countries, such as laterite in Cameroon, is crucial for sustainable development. This study investigates the feasibility and characterization of geopolymer foams based on laterite or a model mixture (metakaolin-hematite) under drastic conditions like fire and freeze-thaw cycles. The results show that these materials have low thermal conductivity and good insulation properties, making them suitable for usage in construction.

Summary: This study evaluated the evolution of physico-chemical properties by mixing different metakaolins. The properties of the mixtures were expressed as a function of different parameters, where granulometric properties depended on the quantity of each source, wettability was related to the amount of available amorphous aluminum, and zeta potential was influenced by the source with the highest amount of siliceous-based impurities. This approach can be applied to geopolymer synthesis.

Summary: This study aims to demonstrate the differences between two series of metakaolin-based geopolymers obtained from silicate solutions with different potassium concentrations (5 and 6 mol/L). The differences between the two solutions were identified by performing various spectroscopic analysis. The reactivity of the solution was found to depend on its degree of condensation, and the characteristics of the geopolymer were influenced by the composition of the silicate solution.

Summary: This study evaluated the impact of different metakaolin mixtures on geopolymer formation and properties. The results showed that aluminum concentration affected the setting time and oligomer formation energy. Regardless of the formulation, the trends in mechanical strength and porosity were similar. Network characteristics were assessed by amorphous material content and in situ infrared spectroscopy analysis.

Summary: This study tested the thermal performances of volcanic ash-based alkali-activated materials at 1000 degrees C using sodium or potassium solutions. After confirming the feasibility of the potassium set, a multidisciplinary characterization was conducted, including spectroscopic, thermal, mechanical, diffractometric, and dilatometric analyses. The formation kinetics of different networks were evaluated. The results demonstrated a correlation between high mechanical properties and lower water content in non-treated samples. Treated samples at 1000 degrees C exhibited higher compressive strengths due to the crystallization of wollastonite, leucite, and nepheline. Additionally, the thermal stability was observed to increase with higher solid content in potassium-based formulations.
