Short summary
Short summary
Surface morphology is critical for enhanced performance in thin films. However, there is limited understanding regarding the accurate control of thin-film morphology. This work provides a systematic way of optimizing different parameters to achieve the desired surface morphologies. Key parameters for controlling thin-film morphology have been identified. Using these parameters, a systematic design schedule for electrosprayed thin films with different surface morphologies has been developed.

Short summary
Short summary
This work demonstrates the feasibility of estimating the ultraviolet (UV) dose experienced by aerosols without using virus-containing droplets. We developed a model system using non-evaporating droplets containing UV-sensitive dyes. These dye-containing droplets were generated and then exposed to UV-C light in a custom-built irradiation chamber. The proposed method could aid in understanding the effect of the suspending medium and droplet size on the UV dose required for bioaerosol inactivation.

Short summary
Aircraft are an important source of both soot aerosols and pollutants, like CO2 and nitrogen oxides (NOx), which also negatively affect human health and the environment. In many cases, strategies to reduce one pollutant may increase another. So, it is vital to have a quantitative understanding of the contribution of each pollutant to negative outcomes so that trade-offs can be made. Here, we review methods to reduce aircraft soot emissions through the use of fuel, engine design, and operation.
