Latent heat thermal energy storage technique has demonstrate to be a better engineering option mainly due to its benefit of supplying higher energy storage density in a smaller temperature difference between retrieval and storage. For this purpose, a micro electro-mechanical system, MEMS-based heat exchanger with microencapsulated PCM (MEPCM) slurry as cold fluid, has been simulated three dimensionally. This work investigates the influence of using MEPCM-slurry on the temperature of the cold and hot fluids. The MEPCM and water properties have been (...) considered temperature dependent. MEPCM-slurry is used with different volume fractions. The result shows that using MEPCM with 25% volume fraction leads to the improvement in fluids temperatures, that is, for hot fluid the rate of temperature reduction increases up to 23.5% and for cold fluid the rate of temperature rise decreases to 9%, compared to using only water in the MEMS.

Michel Gondry and Charlie Kaufman’s 2004 Eternal Sunshine of the Spotless Mind, which celebrated its fifteenth anniversary in 2019, is an extended thought experiment on the nature of memory, minds, and persons. The memory erasure thought experiment presented in the film—and its implications for personal identity—raises poignant questions for the ethicist, epistemologist, neuroscientist, metaphysician, and cognitive scientist. In this paper, I explore the rich insights the film has to offer interdisciplinary studies of memory, providing a case study in how narrative (...) can uniquely contribute to memory research, while also maintaining philosophical rigor and fidelity to scientific discoveries about memory. Turning to the philosophical implications of memory erasure, I consider memory erasure in the context of several leading views of personal identity and proposed answers to the persistence question of personal identity, assessing the challenges and complications that the memory erasure thought experiment brought to life by Eternal Sunshine poses to these theories. I argue that the psychological continuity view of personal identity—in its various iterations—does not allow an individual to truly survive the memory erasure procedure. The memory erasure thought experiment presented in Eternal Sunshine—and its metaphysical and epistemological consequences—reveal how we establish the relationship between memories and selfhood, how to define personhood in the presence of both hypothetical and real-world memory loss, and what experiences we value in human life.
