Summary: Recently, low-cost sensors (LCSs) have been extensively used for monitoring particulate matter (PM) mass concentrations. This study evaluated two commercial LCSs, Plantower PMS3003 and Plantower PMS7003, in the laboratory and field using a reference-grade PM monitor (GRIMM 11-D). The LCSs showed differences in mass concentrations compared to the reference monitor, but a high correlation was observed. Field evaluation showed that the LCSs generally had higher PM mass concentrations, but the sensitivity varied with outdoor PM10/PM2.5 levels and relative humidity. Calibration models improved the accuracy of the LCSs, making them a cost-saving alternative to expensive reference monitors.

Summary: The study aimed to determine ventilation conditions for managing indoor air quality during cooking in a typical South Korean residential home. The PM10 and PM2.5 concentrations varied depending on ventilation conditions, but were high when inappropriate methods were used. Using appropriate ventilation conditions is effective in reducing PM10 and PM2.5 generated during cooking.

Summary: This study presents a new filterless indoor air purifier, the Cloud-Air-Purifying (CAP) air purifier, which uses heterogeneous condensation and supergravity technology to remove fine particles and disinfect bioaerosols. The CAP air purifier showed high efficiency in purifying particulate matter and effectively disinfecting bioaerosols. The study also investigated other factors such as ClO2 release concentrations, noise, and power consumption, which were found to be within acceptable limits.

Summary: In recent decades, particulate matter concentrations in Tehran have often exceeded the WHO guidelines, with annual average PM10 exceeding the limit and PM2.5 concentration surpassing the 24-hour guidance value for more than 50% of the days. Tehran experiences two seasonal PM peaks and two daily peaks, with factors such as traffic and boundary-layer height changes influencing the pollution levels. The indoor PM concentrations in Tehran are significantly higher than outdoor levels, making it crucial for decision makers to develop effective policies for air quality improvement.

Summary: Modern societies are facing increased air pollution, with particulate matter (PM) being one of the major pollutants and causing significant environmental health issues. This study focused on the Ciuc basin and analyzed the time series data of PM2.5, PM10, and TSP from 2010 to 2019 to understand the characteristics of air pollution in this region. The average monthly concentrations of TSP, PM10, and PM2.5 varied within certain ranges, with the highest levels observed during the cold period. The percentage of PM10 exceedances was highest in winter, while lower percentages were observed in autumn and spring. The correlation analysis showed a moderate to high level of correlation among the studied pollutants.

Summary: Air quality, both indoor and outdoor, is crucial for public health. This study introduces a new methodology using low-cost sensors and source apportionment techniques to understand the importance of different air pollution sources on indoor air quality. The results demonstrate the highest concentrations of PM in the bedroom, the highest PM spikes in the kitchen during cooking times, and the highest PM1 concentrations in the office due to outdoor infiltration. Source apportionment analysis shows that up to 95% of PM1 comes from outdoor sources in all rooms.

Summary: In South Korea, particulate matter (PM) pollution, especially indoor PM concentrations, is a significant concern affecting the health of elementary school students. This study investigates the concentration of PM in classrooms and its influencing factors, and discusses measures to reduce PM levels. The findings show that PM concentrations in classrooms often exceed the recommended level by the World Health Organization (WHO), particularly in Asia and Europe. Understanding the factors affecting PM in elementary school classrooms can contribute to the establishment of relevant policies.

Summary: This study demonstrates a precise method to optimize heat generation in high viscosity magnetic colloids by adjusting the Neel relaxation time in core/shell bimagnetic nanoparticles. The magnetic measurements and experiments of magnetic fluid hyperthermia showed that adjusting the shell composition can maximize the specific loss power in viscous media, leading to potential applications in biomedical fields that require smaller particle sizes.

Summary: This study systematically investigated the relationship between elastic behavior and structural properties of polycrystalline Fe0.89Ga0.11 thin films deposited on Si(100) substrates. The results showed that the weights of texture components varied with Ar pressure, residual stress relaxed with increasing Ar pressure, and Young's modulus values remained relatively constant within the studied range of Ar pressure. Additionally, the behavior of residual stress and Young's modulus was correlated with the microstructure evolution.

Summary: The investigation compared the microstructures and deuterium retention properties of beryllium intermetallic compounds (beryllides) with pure beryllium exposed to high density pure deuterium and helium mixed plasmas. The results showed that beryllides demonstrated a reduction in deuterium retention when seeded with helium, while pure beryllium did not show a significant reduction in deuterium retention. The cone structures observed on beryllium surfaces exposed to plasmas were found to be generated by sputtering.

Summary: The study showed that irradiating beryllium samples with high-energy oxygen ions and exposing them to deuterium plasma can reduce the retention of deuterium, but further damaging up to a certain level does not have additional effects on deuterium retention. Transmission electron microscopy was used to check for the existence of bubbles after plasma exposure.

Summary: The dominant decay pathways of argon 2p-2 double-core-hole states were investigated using synchrotron radiation and a magnetic-bottle-type spectrometer coupled with an ion time-of-flight spectrometer. The experiment allowed for efficient multi-electron-ion coincidence measurements to track the Auger cascade step by step. The decay pathways leading to Ar4+ final states via Ar3+ intermediate states were assigned using theoretical ab initio calculations.

Summary: In this theoretical study, we predict the spectrum and angular distribution of XUV superfluorescence from doubly excited states of helium pumped by free-electron laser pulses. Our model overcomes the deficiencies of previous models by treating electromagnetic fields in three dimensions and modeling spontaneous emission using a recently developed approach. Numerical simulations of the 3a 1Po resonance in helium show that the spectral width and angular divergence of emitted radiation vary with gas pressure and pump pulse intensity in a complex way.
