2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, EarlyView.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

Performance evaluation and optimization guidance for steam generating heat pumps with significant temperature lift

Case Studies in Thermal Engineering
Steam generating heat pumps (SGHPs) offer a promising alternative to coal-fired boilers. To address the lack of general optimization strategy of autocascade SGHP (ASGHP) for variable operating conditions and variable cycle configurations, this paper ...

Biointerface Membranes Orchestrating Site‐Specific Osteoimmunomodulatory and Antibacterial Effects for Enhanced Osseous Regeneration in Periodontal Therapy

Advanced Functional Materials, EarlyView.
Here, a biointerface membrane engineered with site‐specific interfacial properties is developed. During implantation between gingival and bone defect, the membrane creates a pro‐osteogenic microenvironment, precisely modulates cellular activities at each biointerface, and facilitates the orchestration of complex healing events, ultimately leading to ...

Research on new cooling and waste heat utilization methods of liquid ring vacuum pump for coal mine gas extraction

Meikuang Anquan
The high temperature of gas drainage liquid ring vacuum pump is an important reason for its low operating efficiency and short service life. Based on the wasted power dissipation theory of liquid ring pumps, the heat generation-heat dissipation mechanism

Centrifugal compressor design for high-temperature heat pumps

Applied Thermal Engineering
Heat pumps are identified as crucial technology for decarbonising the heat production. Especially for large-scale, high-temperature heat pumps, the use of centrifugal compressors has been seen as an attractive technological option, but there are very few detailed studies available discussing the compressor designs with different refrigerants for high ...
