Research Progresses of Flash Evaporation in Aerospace Applications

Wei Ma, Siping Zhai, Ping Zhang, Yaoqi Xian et al. • International Journal of Aerospace Engineering (2018)

Liquid is overheated and evaporated quickly when it enters into the environment with lower saturation pressure than that corresponding to its initial temperature. This phenomenon is known as the flash evaporation. A natural low-pressure env...

Impossibility of universal work extraction from coherence: reconciling axiomatic and resource-theory approaches

Samuel Plesnik, Maria Violaris • New Journal of Physics (2024)

We compare how the impossibility of a universal work extractor from coherence arises from different approaches to quantum thermodynamics: an explicit protocol accounting for all relevant quantum resources, and axiomatic, information-theoret...
