Summary: The addition of calcined quarry dust (CD) to lime/Na2SO4-activated slag promoted the slag reaction kinetics, increased compressive strength, improved initial and final setting times, enhanced hydration product content, reduced total porosity, and resulted in a denser matrix, all contributing to the development of strength in the composites. Compared to traditional NaOH- or Na2SiO3-activated slag, the composites modified with CD are cost-competitive and environmentally benign.

Summary: The construction industry needs to achieve net-zero carbon emissions by 2050 due to its heavy reliance on non-renewable energy and contribution to greenhouse gas emissions. Construction activities account for 36% of global energy consumption and 39% of global carbon dioxide emissions. Government policies, carbon emission analysis models, and sustainable materials are essential for reducing carbon emissions. This review focuses on the history, carbon emissions, policies, models, life cycle assessment, and sustainable materials in green construction, presenting national policy frameworks and technology roadmaps to achieve carbon neutrality in the building sector.

Summary: The tuning of porosity and surface properties of nanoparticles, especially on carbon-based nanomaterials, through a 'greener' or self-activation synthesis technique for electrical charge storage is progressing. Activated carbon nanoparticles synthesized at 900 degrees Celsius exhibit a maximum surface area of around 360 m(2) g(-1) with an average pore size of about 2 nm. By using different electrolytes and fabricating two symmetric supercapacitors, aqueous (1 M KOH) and solid-state (PVA/KOH), it is found that the latter performs better with a wider voltage window and superior energy density.

Summary: As global efforts to reduce carbon emissions intensify, the principles of net-zero emissions or carbon neutrality are becoming increasingly important, leading to the implementation of various strategies worldwide to reduce carbon emissions. Cement manufacturing, a major source of emissions globally, has set goals to reduce emissions by over 60% by 2050. This review article examines the effects of the combined composition of cement and alkali-activated construction materials, as well as carbonation curing conditions, on compressive resilience.

Summary: This study investigated the characteristics of activated carbon from cashew nut shell produced by potassium hydroxide activation at 600 degrees C in an N2 atmosphere. The sample obtained with a CNS/KOH ratio of 1:1 had the highest surface area compared to other ratio samples. The effects of contact time, pH, adsorbent dose, and initial dye concentration on brilliant green (BG) removal efficiency were studied using the CNS/KOH ratio of 1:1 sample as the adsorbent. The Langmuir isotherm provided the best fit for the experimental equilibrium data, with a maximum BG adsorption capacity of 243.90 mg/g.

Summary: The issuance of green bonds significantly improves firms' overall environmental performance and their capacities to create new environmental technologies and processes, but has a less clear effect on carbon emissions intensity, which requires additional time to improve. The findings highlight the importance of green bonds in financing energy transition in the corporate sector and provide evidence to encourage policymakers to strengthen the legal framework relating to their issuance.

Summary: As climate change worsens over time, the importance of green growth and green innovation in reducing environmental pollution and promoting cleaner economic growth and a healthy environment becomes increasingly evident. However, existing research studies have not adequately examined the impact of green growth, green innovation, and information and communication technology (ICT) on CO2 emissions. This study aims to fill this research gap by investigating how green growth influences CO2 emissions in Pakistan, specifically in relation to green innovation and ICT. The findings highlight the significant contribution of green growth and green innovation to improving environmental sustainability in Pakistan, while also revealing a positive relationship between ICT and CO2 emissions. The study emphasizes the need for policymakers and regulators to prioritize the promotion of a green growth agenda and green innovation to mitigate CO2 emissions and achieve sustainable development goals.

Summary: To achieve carbon neutrality and peak carbon emissions, it is important to accelerate the growth of renewable energy. The use of green technology advancements can balance economic growth with environmental security. However, there is a lack of empirical research on the connection between green technology advancements and CO2 emissions, particularly in developing countries. The findings of this study suggest that urbanization and green technological developments have a positive impact on reducing CO2 emissions, while investments in renewable energy and the industrial sector fail to reduce pollution levels. The positive and negative coefficient of income per capita indicates that the inverted U-shaped Environmental Kuznets Curve hypothesis is valid in Chinese provinces.

Summary: From a thermodynamic perspective, temperature is clearly defined for ideal physical systems, but in indoor environments, it is influenced by complex factors. Processes such as diffusion, partitioning equilibria, and chemical reactions are greatly affected by temperature, while transport processes are influenced by spatial temperature, momentum, pressure gradients, and indoor material properties. The thermal comfort needs of occupants and building design requirements also play a significant role in indoor environmental conditions.

Summary: While high-resolution MS is suitable for novel PFAS identification and quantification, low-resolution MS/MS is the more commonly used and affordable approach for routine PFAS monitoring. However, the interference of chemical compounds in the quantitative ion channel hinders the verification of PFPeA and PFBA on low-resolution instrumentation. Adjustments to analytical methods, such as altering LC conditions and using matched internal standards, are recommended to investigate and confirm PFBA and PFPeA detections in both biological and environmental samples.

Summary: In 2019, a study conducted by the Colorado Department of Public Health and Environment's Air Pollution Control Division found that biogenic VOC emissions in cannabis cultivation facilities vary widely, with the highest emissions occurring during post-harvest activities such as trimming. The dominant terpenes measured in all facilities were beta-myrcene, terpinolene, and D-limonene.

Summary: Recent evidence suggests that indoor ozone chemistry products contribute to cardiovascular pathophysiology through the formation of reactive oxygen species (ROS) on indoor surfaces. The yield of condensed-phase ROS on a model indoor surface film exposed to ozone was measured, and it was found that approximately 46% of the consumed ozone formed ROS. These ROS persisted on the surface for several hours and could continue to form even in the absence of ozone.

Summary: During the Indoor PFAS Assessment (IPA) Campaign, concentrations of nine neutral PFAS were measured in air and cotton cloth in 11 homes in North Carolina. The study found that fluorotelomer alcohols were the dominant species in indoor air, while perfluorooctane sulfonamidoethanols accumulated most significantly in cloth. Cloth-air partition coefficients were derived for different PFAS and were positively correlated with the octanol-air partition coefficient. Temperature was found to have the greatest effect on PFAS accumulation.

Summary: Field studies suggest that indoor sources of reactive oxygen species (ROS) contribute to measured ROS on particulate matter (PM) in indoor air. This study supports the hypothesis that ozone-induced formation of organic peroxides (OPX) on indoor surfaces, and subsequent partitioning to aerosols, is sufficient to explain field observations.
