Published: December 2023

High-quality air is essential for human survival. The present-day has a negative effect on air quality. Air contamination from the harmful compound H2S is an important problem. The primary source of H2S discharges is the oil and gas industry, where it is a by-product of resource harvesting and processing. Further sources of H2S discharges into the atmosphere include mining, waste management, and fossil fuel burning. H2S generates a malodorous scent resembling that of decayed eggs, which can prompt respiratory discomfort and irritation in humans and animals. At elevated concentrations, it may induce toxicity and even fatalities. Biofiltration is one of the latest remarkable technological advances for mitigating this issue. This method employs microorganisms to convert H2S into less harmful compounds. Biofiltration offers the major benefit of low operational expenditure and minimal environmental impact. This paper contributes to our comprehension of the microbial parameters, designs, models, applications and processes that affect biofilter efficiency. Diffusion-based biofiltration models show greater efficacy in design systems. Furthermore, advances in media, including the use of hollow cylindrical particles, have increased the efficiency of biofiltration. Sulfur-oxidizing microorganisms, such as Thiobacillus sp., play a pivotal role in decreasing H2S compounds. It is crucial to regularly monitor and regulate moisture levels, pH, temperature, and nutrient content to secure optimal and consistent biofiltration performance. The technology's effectiveness and stability heavily depend on precise control of these parameters. Biofiltration technology is hailed as a promising approach to manage H2S compounds, safeguard air quality, and preserve human health and the environment.

Abstract

Assam experiences significant floods every year, that causes damage to both people and infrastructure. By acquiring and analysing data which is required for hydrological research, geographic information systems and remote sensing technologies can assist to comprehensive flood management. A collection of 10 parameters, including elevation, slope, distance from the river, distance from road, drainage density, flow accumulation, land use and land cover, and Normalised Difference Vegetation Index derived from Landsat 8 OLI/TIRS images, the Environmental System Research Institute’s land cover and the Shuttle Radar topographic Mission’s Digital Elevation Model data from the United States Geological Survey have been used. The Barak basin of Assam's Cachar District was selected as our study area. After the selection of all the components, weights were assigned to each component through the Analytical Hierarchy Process. The influence value of the Topographic Wetness Index was assigned the highest weight in the final weighted overlay analysis that combined all the components. The output zones were divided into five flood prone zones as very low, low, moderate, high, and very high. The results show that 22.67% of the total area is characterized by high-flood zones, while extremely high flood-risk areas cover 0.01% of the area. The high flood-risk zones are densely populated. The Silchar town of Cachar falls under a very high-risk zone, with the highest population density. This work will help policymakers, planners, researchers and emergency responders with disaster preparedness and management.

Abstract

Intravascular surgical instruments necessitate precise navigation within narrow vessels, requiring maximum flexibility, minimal diameter, and high degrees of freedom. However, existing tools often lack adequate control during insertion due to undesirable bending, which not only limits vessel accessibility but also poses a risk of tissue damage. The advancement of nextgeneration instruments aims to develop hemocompatible untethered devices that achieve precise control through external wireless forces and torques applied from outside the body. However, achieving this goal remains complex due to the challenges involved in testing and implementing untethered magnetic robots (UMRs) in clinical environments. These challenges encompass wireless actuation, non-invasive localization, biocompatibility, control robustness, and effective engagement. In this study, we assess the operational effectiveness of hemocompatible UMRs in clinical settings. We utilize an ex vivo porcine aorta model that accounts for factors such as varying blood-vessel diameters, varying blood flow rates, and the presence of renal aortic side-branches. This comprehensive approach enables us to analyze the robots’ motion dynamics within vessels, closely simulating real physiological and anatomical conditions. Our findings, in the absence of clotting, reveal a consistent linear reduction in UMR swimming speed against increasing arterial blood flow. Furthermore, our experiments showcase the UMR’s ability to generate sufficient force to navigate against a maximum arterial flow rate of 67 mL/min. Using the predicted and observed physical interactions of the UMRs, we effectively demonstrate preliminary proof-of-concept locomotion in a difficult-to-access target site, allowing us to navigate through the abdominal aorta and successfully reach the distal end of the renal artery.

Abstract
The rapid development of the city leads to the continuous updating of the ratio of land use allocation, especially during the flood season, which will exacerbate the significant changes in the spatial and temporal patterns of urban flooding, increasing the difficulty of urban flood forecasting and early warning. In this study, the spatial and temporal evolution of flooding in a high-density urban area was analyzed based on the Mike Flood model, and the influence mechanisms of different rainfall peak locations and infiltration rate scenarios on the spatial and temporal characteristics of urban waterlogging were explored. The results revealed that under the same return period, the larger the rainfall peak coefficient, the larger the peak value of inundation volume and inundation area. When the rainfall peak coefficient is small, the higher the return period is, and the larger the peak lag time of the inundation volume is, in which P = 50a, r = 0.2, the delay time of the inundation volume for the inundation depths H > 0.03 m and H > 0.15 m reached 32 min and 45 min, respectively, At the same time, there are also significant differences in the peak lag time of waterlogging inundation volume in different inundation depths. The greater the inundation depth, the longer the peak lag time of waterlogging inundation volume, and the higher the return period, the more significant the effect of lag time prolongation. It is worth noting that the increase in infiltration rate will lead to the advance of the peak time of inundation volume and inundation area, and the peak time of the inundation area is overall more obvious than that of inundation volume. The peak times of inundation volume and inundation area were advanced by 4 ~ 8 min and − 2 ~ 9 min for H > 0.03 m and H > 0.15 m, respectively, after the increase in infiltration rate; and the higher the return period, the smaller the rainfall peak coefficient and the longer the advance time. The spatial and temporal characteristics of waterlogging under different peak rainfall locations and infiltration capacities obtained in this study can help provide a new perspective for temporal forecasting and warning of urban waterlogging.

Abstract
The surface immobilization of molecular catalysts is attractive because it combines the benefits of homogeneous and heterogeneous catalysis. However, determining the surface coverage and the distribution of a molecular catalyst on a solid support is often challenging, inhibiting our ability to control catalytic performance. Here, we demonstrate that scanning transmission electron microscopy can image the location of the metal center in surface-attached transition metal complexes with atomic resolution. Using a machine learning model, we can analyze many images to determine surface coverage and distribution in a non-destructive manner. This allows us to establish how changes to the molecular catalyst affect surface coverage and distribution. Our work describes a new method to characterize surface-attached catalysts, which is likely general to many systems.

Abstract

The coefficient of thermal expansion (CTE) of biological tissues is an important parameter in the application of many energy-based biomedical therapies. In this study, we employ 2D Digital Image Correlation (DIC) to monitor surface displacement and determine the corresponding strain in tissue samples subjected to temperature fluctuations in a water bath. By combining this data with recorded water temperature information, we create comprehensive maps of the CTE for porcine liver specimens. DIC provides a comprehensive analysis of the specimen's thermomechanical response, providing insight into the detailed strain behavior and structural characteristics of the tissue under investigation.
