Summary: The experimental study showed that incorporating WEEP as partial replacement of aggregates in concrete can decrease the mechanical strength and durability of the concrete, mainly due to the poor bonding between WEEP and natural aggregates caused by the smooth surface of WEEP. However, the addition of pozzolans such as metakaolin and condensed silica fume can increase the density of the concrete matrix and reduce the interfacial transition zone, thus enhancing the overall performance of mixes containing WEEP.

Summary: This study examined the bond durability behavior between high-strength fiber reinforced concrete (FRC) and sand-coated basalt FRP (BFRP) bars. The results showed that all environmental conditions degraded the bond, with the exposure to 50 degrees C seawater causing the most significant degradation. However, the use of basalt fibers helped to mitigate the loss of bond strength. Two analytical models accurately predicted the bond stress-slip relationship.

Summary: This paper introduces a new approach for self-healing concrete using engineered aggregates (EAs). The EAs were found to resist the conventional concrete mixing methods and effectively deliver healing agents when cracks appear in concrete. The mechanical properties and self-healing efficiency of the concrete with different healing agents were examined. The results show that self-healing EA concrete could regain more than 50% of its original strength and stiffness and reduce water permeability significantly.

Summary: This study investigates the possibility of replacing cement and fine aggregates with fine slag material (Alccofine 1203) and coal bottom ash, respectively. The study is conducted in two phases, where in Phase I, coal bottom ash is partially replaced with different percentages (10%, 20%, 30%, 40% and 50%) and in Phase II, cement is partially replaced with Alccofine at different percentages (5%, 10%, 15% and 20%). The results show that the inclusion of 40% coal bottom ash and 15% Alccofine achieved high-strength concrete with an 8.14% increase in cost compared to the control mix. The significance of this work lies in the fact that it demonstrates the potential of using industrial waste such as coal bottom ash for sustainable concrete production.

Summary: The environmentally friendly byproduct of fruit plants, fig leaf, has been successfully used as an adsorbent for methylene blue dye. The prepared fig leaf-activated carbon (FLAC-3) showed good adsorption performance, with an adsorption capacity of 24.75 mg/g for 0.08 g and 41 mg/g for 0.02 g. The adsorption process followed the Langmuir isotherm model, forming a monolayer on the surface of the adsorbent. These findings demonstrate that FLAC-3 is a low-cost adsorbent with potential for efficient removal of cationic dye methylene blue.

Summary: Intoxication with methanol commonly occurs through ingestion, inhalation, or contact with methanol-containing formulations. It can lead to central nervous system suppression, gastrointestinal symptoms, and metabolic acidosis, resulting in impaired vision and blindness. Early detection of high blood methanol concentrations is important for intervention. Methanol is digested by alcohol dehydrogenase (ADH) and redistributed in the body's water. Methanol poisoning is relatively uncommon but can affect a large number of individuals simultaneously, making it a significant concern in clinical toxicology. The COVID-19 pandemic has led to misconceptions about methanol's preventive capabilities, resulting in mass poisoning incidents and high mortality rates.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: The utilization of smart water in EOR operations has gained attention, but more research is needed to understand the complex mechanisms involved. This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.

Summary: In this study, high-performance solid catalysts based on phosphotungstic acid (HPW) supported on Zr-SBA-15 were synthesized and evaluated for the one-pot conversion of furfural (FUR) to γ-valerolactone (GVL). The catalysts were characterized using various techniques, and the ratio of HPW and Zr was found to significantly affect the selectivity of GVL. The HPW/Zr-SBA-15 (2-4-15) catalyst exhibited the highest GVL yield (83%) under optimized reaction conditions, and it was determined that a balance between Bronsted acid sites (BAS) and Lewis acid sites (LAS) was crucial for achieving higher catalytic performance.
