Performance and optimization study of graded thermal energy storage system for direct steam generation dish type solar thermal power

Case Studies in Thermal Engineering, 2023
The traditional dish type Stirling power generation system cannot have the thermal energy storage system, so the power generation is discontinuous. The direct steam generation dish type solar thermal power, which includes the thermal energy storage ...

Label‐Free Myelin Fingerprinting: An Adult Human Post‐Mortem Brain Slice Platform via Coherent Anti‐Stokes Raman Spectroscopy

Advanced Science, EarlyView.
A serum‐free, air–liquid interface organotypic slice culture model preserves human post‐mortem corpus callosum tissue, successfully recovering from slicing trauma to reflect the donor's underlying disease state. Pairing label‐free Coherent anti‐Stokes Raman scattering (CARS) microscopy with k‐means clustering enables objective, high‐resolution ...

Efficient Adsorption‐Based Direct Air Capture Via Triply Periodic Minimal Surface Architectures

Advanced Science, EarlyView.
Architected triply periodic minimal surface (TPMS) contactors reshape direct air capture by replacing straight‐channel diffusion limits with convection‐enhanced CO2 transport. Chaotic advection thins boundary layers and exposes fast adsorption sites, enabling 70%–75% more fast sites, 114% higher productivity, and 51.8% lower energy consumption than ...

D–A Type Perylene Micelles With Synergistic Charge/Energy Transfer for Dual‐Path ROS Generation and Enhanced Photocatalysis

Advanced Science, EarlyView.
Dual‐state activation of singlet and triplet excitons is achieved in perylene‐based nanomicelles via donor engineering. By synergistically pairing charge transfer with energy transfer pathways, while concurrently enabling pollutant pre‐enrichment, this strategy establishes spatial coupling between efficient ROS generation and rapid mineralization ...

Development of geothermal power generation system using geothermal fluids under harsh conditions

Energy Conversion and Management: X
High-enthalpy geothermal fluids contain significant amounts of impurities, corrosive gases, and non-condensable gases (NCGs). In addition, steam is superheated and contains no liquid water, which can cause problems such as corrosion and scaling if ...

The atmospheric steam engine as energy converter for low and medium temperature thermal energy [PDF]

, 2013
Many industrial processes and renewable energy sources produce thermal energy with temperatures below 100 °C. The cost-effective generation of mechanical energy from this thermal energy still constitutes an engineering problem.
