Thermodynamic Analysis of an Electrochemical Refrigeration Cycle

, 1997
The coupling of a water-based electrochemical cell and fuel cell are discussed as a means to form a refrigeration cycle. In the proposed configuration, the process fluids can be passively driven through the flow circuits.

SMAD4 Palmitoylation Drives a Metabolic‐Transcriptional Circuit to Promote Tumorigenesis and Confers Radiosensitivity in Pancreatic Cancer

Advanced Science, EarlyView.
This study identifies palmitoylation as a novel regulatory modification of SMAD4, mediated by ZDHHC22/APT2. It activates fatty acid synthesis, creating a self‐reinforcing SMAD4–FASN–palmitate feedback loop that drives pancreatic cancer growth and enhances radiotherapy sensitivity.

Ejector Performance of a Pump-less Ejector Refrigeration System Driven by Solar Thermal Energy

, 2012
Ejector refrigeration is considered as one of the three main ways of refrigeration and air-conditioning to utilize lowgrade energy. Use of pump-less technology to eliminate the mechanical circulating pump of the working fluid from condenser to generator ...

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

Corals and Reef‐Dwelling Fish Regulate Carbon Storage and Cycling Processes in Coral Reef Ecosystems

Advanced Science, EarlyView.
Coral reefs are biodiversity hotspots, yet their role in carbon storage and cycling remains poorly understood. Using field surveys and modeling in the South China Sea, we reveal the overlooked potential of carbon storage in reef ecosystems and how reef fish, corals, and surface sediment jointly shape reef carbon reservoirs.

Performance Analysis of Air-refrigeration System for Data Center Cooling

Zhileng xuebao, 2022
In this study, an air-refrigeration system for data center cooling is proposed. The effects of pressure ratio, ambient temperature, indoor temperature, and rotating component efficiencies (compressor and expander) on cycle performance were studied by ...

Study on a Novel Absorption Referigeration System at Low Cooling Temperatures

, 2012
A novel absorption refrigeration system is proposed in this context using R134a+R23 mixed refrigerants and DMF solvent. The new system uses two-staged absorber in series to reduce the evaporation pressure and can obtain a lower refrigeration temperature ...
