Research Status of Ammonia Vapor Compression High-temperature Heat Pump System

Zhileng xuebao, 2021
High-temperature heat pumps are an important means to solve the dual utilization of cold and heat and realize energy saving and emission reduction. Owing to the limitation of refrigerant use, natural working fluid has become the focus of research.

Efficient control of cascade heat pumps using variable speed compressors

Scientific African, 2022
Building load varies continuously throughout the year, causing heat pumps to operate at part load. At such situations, the capacity of the heat pump needs to be controlled to meet the building load.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Development of a high-resolution top-down model to estimate actual household-level heat pump electricity consumption

Environmental Research: Infrastructure and Sustainability, 2023
Heat pumps can play an important part in decarbonizing the residential sector due to their use of electricity instead of fossil fuels, and their high efficiency, which often exceeds 100%.

Proteasomal degradation of intracellularly expressed Amblyomin‐X limits suicide gene therapy potential in melanoma cells

FEBS Open Bio, EarlyView.
This study explores the feasibility of expressing the antitumoral protein Amblyomin‐X through a suicide gene therapy approach and investigates its intracellular fate after gene delivery. Although the gene is efficiently expressed, melanoma cells rapidly degrade the Amblyomin‐X protein via proteasome activity.

Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

FEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.
