Summary: Particulate air pollution is a global health concern, and this study finds that indoor plants are not effective in removing airborne particulate matter. The study quantified the deposition velocities and clean air delivery rates of different plant species and compared them with filter-based air purifiers. The results show that plant systems cannot compete with traditional air purifiers, and a large quantity of plants is required to achieve modest reductions in indoor PM concentrations.

Summary: This study found that the total OH reactivity of human gaseous emissions is influenced by indoor temperature, humidity, clothing coverage, and indoor ozone concentration, primarily due to reactions between ozone and organic skin-oil constituents. The emission ratios of VOCs and ammonia remained relatively stable under different conditions, but the total OH reactivity exhibited greater diversity with higher temperature and humidity.

Summary: Close contact routes, particularly in indoor environments, have a significant impact on the transmission of SARS-CoV-2. This study developed a digital wearable device to automatically record human close contact behavior, and evaluated the correlation between aerosol exposure and close contact behaviors. The findings showed that restaurants had the highest close contact ratio and face-to-face pattern during close contact, leading to the highest aerosol exposure volume.

Summary: Human daily activities such as cooking and cleaning can affect indoor air quality by emitting volatile organic compounds (VOCs) and forming secondary compounds through reactions with ozone (O3) and hydroxyl radicals (OH). However, our understanding of the formation processes of secondary VOCs is still limited. In this study, we measured the primary VOCs emitted by a commercial floor-cleaning detergent and the secondary compounds formed by the reaction of O3 with the detergent using high-resolution mass spectrometry. We also developed reaction mechanisms to describe the formation of these secondary VOCs.

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.

Summary: This study examined the impact of indoor thermal conditions on EEG signals and employed logistic regression to differentiate indoor thermal comfort. Twenty male participants were recruited to record resting EEG signals under different combinations of temperature, humidity, and air velocity. Subjective questionnaires were utilized to gather individuals' perceptions of the environment and used as criteria to develop logistic regression models. The findings demonstrated that theta, beta 1, beta 2, and gamma waves were highly similar at 22°C and 25°C, as well as velocity for all EEG waves at 0.5 and 1 m/s. Additionally, 70% relative humidity was determined as the cut-off point for high humidity in the humidity test for beta 1, beta 2, and gamma waves. Moreover, regression models were developed utilizing frequency bands associated with comfort, with the overall model accurately categorizing 88.6% of the data. This research serves as a foundation for further exploration of the interconnected environment and neuronal mechanisms.

Summary: The study investigated the removal efficiency of VHP on indoor materials and emissions of organic compounds, comparing them with ozone and chlorine dioxide. Most materials exhibited relatively constant and high deposition velocities for VHP, while showing different deposition velocities for O-3 and OClO. The release of organic compounds from materials was relatively low, lower than observed values for ozone.

Summary: Analyses have shown that microplastic pollution in indoor environments could be a significant hygienic problem. Microplastics can be generated from abrasion, added to household products, and found in synthetic materials. There is also a debate on whether particulate emissions from 3D printing should be classified as microplastics or nanoplastics. Textiles are also considered as a potential source of indoor microplastics. It is recommended to further investigate residents' exposure to microplastics and to implement preventive measures.

Summary: Vuilleumier refrigerators are devices that utilize heat from a source above ambient temperature to provide cooling power. They are particularly useful in situations where waste heat is abundant but electrical energy is scarce. The design of these refrigerators must compensate for mechanical losses with power gained from pressure differences in order to operate solely on heat. This study focuses on optimizing the design of such a device for heat-only operation to maximize cooling power.

Summary: The semiconductor industry requires constant upgrading of metrological methods and equipment to accommodate smaller and more complex nanostructures. Nanometrology plays a crucial role in accurately determining the structural features and elemental composition of nanoscale gratings. Scatterometry and X-ray fluorescence in the soft X-ray and extreme ultraviolet spectral ranges are ideal for this task. This study introduces a new compact measurement chamber that can simultaneously detect the elastically scattered signal and the fluorescence of nanoscale grating samples.

Summary: New buildings often have high initial concentrations of VOCs, causing discomfort among occupants. Traditionally, running the ventilation system continuously for a year is practiced to reduce VOC levels, but it may result in unnecessary heat losses. This article proposes a new approach called VOC-passport, combining early VOC measurements and a calculation model to optimize ventilation strategies. The proposed model is successfully tested in two newly built office rooms and provides an effective way to improve indoor air quality in new buildings without compromising energy efficiency.

Summary: Thanks to additive manufacturing (AM) processes, components with complex geometries can now be flexibly produced. However, AM technologies have only been widely used in limited industrial applications due to high manufacturing costs. This study presents a new approach for optimizing component arrangement in order to reduce manufacturing costs. An example is used to demonstrate a 70% increase in the number of components on a building platform or a 44% reduction in the number of building platforms needed. A three-step method is proposed for automatic optimization of manufacturing preparation for AM components in the future.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
