Advanced Engineering Materials, EarlyView., 2023 A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

Novel Regression and Least Square Support Vector Machine Learning Technique for Air Pollution Forecasting [PDF]
, 2023 Air pollution is the origination of particulate matter, chemicals, or biological substances that brings pain to either humans or other living creatures or instigates discomfort to the natural habitat and the airspace. Hence, air pollution remains one of the paramount environmental issues as far as metropolitan cities are concerned.

Air Pollution and Innovation [PDF]
Journal of Environmental Economics and Management, 2021 Existing estimates of the economic costs of air pollution do not account for its effect on inventive output. Using two weather phenomena as instruments, we estimate this effect in a sample of 1,288 European regions. A decrease in exposure to small particulate matter of 0.17 micro-gram/m3 -- the average yearly reduction in Europe -- leads to 1.7% more ...

Asthma and air pollution [PDF]
Italian Journal of Pediatrics, 2014 During the last decades research all over the world has highlighted the deleterious effects of pollution on respiratory health of adults and children. Nevertheless, air pollution still represents a significant threat to health. Children are more sensitive than adults to pollutants for several factors: increased respiration relative to body size ...

Network approach reveals the spatiotemporal influence of traffic to air pollution under the COVID-19 [PDF]
, 2022 Air pollution causes widespread environmental and health problems and severely hinders the life quality of urban residents. Traffic is a critical for human life and its emissions are a major source of pollution, aggravating urban air pollution. However, the complex interaction between the traffic emissions and the air pollution in the cities has not ...

Criteria Air Pollutants and Toxic Air Pollutants
Environmental Health Perspectives, 2000 This review presents a brief overview of the health effects and exposures of two criteria pollutants--ozone and particulate matter--and two toxic air pollutants--benzene and formaldehyde. These pollutants were selected from the six criteria pollutants and from the 189 toxic air pollutants on the basis of their prevalence in the United States, their ...
