Phase-shift nanoemulsions (PSNE) can be vaporized using high intensity focused ultrasound to enhance localized heating and improve thermal ablation in tumors. In this report, the preparation of stable PSNE with a narrow size distribution is described. Furthermore, the impact of vaporized PSNE on ultrasound-mediated ablation is demonstrated in tissue-mimicking phantoms.

Lipophagy is a selective form of autophagy that involves the degradation of lipid droplets. Dysfunctions in this process are associated with cancer development. However, the precise mechanisms are not yet fully understood. This protocol describes quantitative imaging approaches to better understand the interplay between autophagy, lipid metabolism, and cancer progression.

FAQs
Optical instruments infer droplet dimensions from how droplets scatter light, while electrical methods evaluate changes in an electrical signal associated with the sample. Image-based systems capture droplets directly for dimensional analysis. These approaches can describe the same spray or liquid system differently because each responds to measurement conditions, droplet shape, concentration, or the observable selected by the instrument.
A distribution shows how droplet dimensions are spread across a population, rather than reducing the sample to one representative value. That distinction matters because evaporation, transport, deposition, mixing, and process efficiency can depend on the range of sizes present. Engineers can therefore compare equipment and operating conditions more meaningfully when the reported result preserves variation within the droplets.
The measured distribution depends not only on the droplets but also on how the sample is presented to the instrument. Droplet shape can influence the signal or image used to infer size, while concentration can alter the measurement response. Sampling conditions can likewise change the observed population, so consistent conditions are important when comparing runs, devices, or operating states.
A practical workflow begins by identifying the spray, emulsion, fuel-injection stream, or other liquid system and defining the operating condition to compare. The sample is then characterized with an instrument based on light scattering, electrical response, or imaging. Results should be recorded as a size distribution together with the sampling conditions, concentration, and relevant droplet-shape considerations.
Engineers use the measurements to optimize atomizers and sprays, where droplet dimensions influence how liquid evaporates, travels, deposits, and mixes. Comparing distributions under different equipment or operating conditions can reveal changes in process behavior without relying on a single diameter. This supports equipment comparison, quality control, and performance prediction for engineered liquid-delivery systems.
In fuel injection, pharmaceutical delivery, and agricultural applications, droplet dimensions help relate liquid delivery to evaporation, transport, deposition, and mixing. The measurement does not merely describe the droplets; it provides evidence for evaluating process efficiency and consistency. Engineers can use the resulting distributions to compare designs, monitor quality, and assess how performance may change across operating conditions.
