Performance analysis of multistage high‐temperature heat pump cycle

Energy Science & Engineering, 2023
AbstractHigh‐temperature heat pumps (HTHPs) that can supply heat at temperatures at and above 200°C have the potential to increase energy efficiency and decrease carbon dioxide (CO2) emissions in industrial processes. In this study, three reversed Rankine cycles using water vapor (R‐718) as the working medium, with different intercooling strategies ...

Ultra-high-temperature electrocaloric heat pump

Energy Conversion and Management
Nearly a quarter of waste heat is generated at temperatures exceeding 300°C, yet conventional heat pump technologies remain inefficient in recovering and utilizing heat from such high temperature sources. In this study, we introduce a novel electrocaloric heat pump designed to operate with heat sources and sinks at ultra-high temperatures. The proposed

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
