Summary: Monochloramine, dichloramine, and trichloramine were measured in the ambient atmosphere of downtown and suburban Toronto. The results show that chloramines are prevalent in urban areas, with NCl3 exhibiting a diel pattern and a strong correlation between NH2Cl and NHCl2. Photolysis of chloramines contributes to the production of chlorine atoms and is an important source of Cl in urban areas.

Summary: Iron-modified biochar (FeMBC) materials were prepared for effective removal of volatile methylsiloxanes (VMS) in biogas, with FeMBC-3 exhibiting the highest adsorption capacity due to its well-developed microporous structure. The adsorption of VMS on FeMBC-3 was found to be a spontaneous and exothermic process, making FeMBC a promising adsorbent for biogas up-gradation.

Summary: This mini review discusses the role of malondialdehyde (MDA) in the molecular mechanisms of primary atherosclerotic vascular wall lesions. It highlights the important role of chemically modified LDL particles containing MDA in atherogenesis, rather than oxidized LDL. The review also presents experimental evidence of MDA damaging the endothelial glycocalyx, impairing the endothelium's ability to regulate arterial tone.

Summary: Amaranth species are a diverse group of plants with many positive biological effects due to their secondary metabolites. The 'Pribina' variety showed higher levels of total phenolic compounds, total flavonoids, rutin, and antioxidant activity compared to the 'Zobor' variety. The content of total phenolic substances, total flavonoids, and rutin were positively correlated with the antiradical and antioxidant activities of the extracts.

Summary: Plants are used globally as an alternative to conventional drugs in treating various diseases. Dragon fruit, belonging to the Selenicereus genus, has been studied for its antioxidant activity. However, studies on the chemical constituents and biological activities of the cladodes (leaves) are limited. This study showed that different varieties of the same species of dragon fruit have differences in their metabolite profiles, emphasizing the importance of identifying the specific variety used in studies.

Summary: Research suggests that the Himalayan region may act as a significant "aerosol factory" contributing to the upper tropospheric aerosol population. This process is mainly driven by organic biogenic precursors with little involvement of anthropogenic pollutants. Newly formed biogenic particles in the Himalaya can double the background aerosol concentration in the free troposphere.

Summary: Chevrel Phases, MxMo6S8, are a class of heterogenous catalysts with unique combination of low-coordinate molybdenum atoms, tuneable oxidation state, thermal stability, and dual Lewis acidity & basicity, making them excellent candidates for fundamental catalytic reactions. Recent developments in synthesis techniques have lessened historical constraints, but the catalytic community has been slow to adopt these advances. This review summarises five decades of catalytic reports, identifies trends and gaps within the literature, and provides perspective on future directions for the catalytic application of Chevrel Phases.

Summary: The study investigates the cytotoxic effects of orthodontic brackets using the method of single cell tracking. The results show that bracket-conditioned media reduce cell division and migration, increase the rate of asynchronous sister cell division, and have no clear effect on cell morphology. This study concludes that orthodontic brackets have cytotoxic effects, and single cell tracking is an effective method for studying subtle biomaterials cytotoxicity.

Summary: In this study, an Australian First Nations-first approach is chosen to understand the chemical elements, aiming to change the practice of chemistry by engaging with cultural heritage and knowledge. This approach acknowledges the unique position of Aboriginal and Torres Strait Islander peoples in the Australian context. The paper explores how this approach could be implemented in Sydney on Aboriginal lands, led by Aboriginal people and incorporating local knowledge. The work so far has involved two years of meetings and discussions to determine appropriate ways of collaboration, while reflecting on the impact of the Periodic Table and considering the contribution of Indigenous knowledges to a broader chemistry curriculum.

Summary: Innovative and robust photosensitisation materials in the form of Metal-Organic Frameworks (MOFs) have been shown to lower the overpotential required for CO2 reduction to CO, along with facilitating charge transfer reduction of a rhenium molecular electrocatalyst, ultimately leading to lower overpotential for CO generation. This study demonstrates the importance of through-space Intervalence Charge Transfer (IVCT) within cofacial units in MOFs in achieving light-harvesting functionalities, offering new directions for the design philosophy behind such materials.
