Flammability Comparison and Flame Retardancy Research on R32 and R1234yf

open access: yesZhileng xuebao, 2021
Halogenated alkanes and halogenated olefins, especially fluorine substitutes, are currently the most widely used synthetic refrigerants. With the implementation of a series of increasingly stringent environmental regulations, most optional fluorinated ...

Improving the energy effectiveness of domestic refrigerators by the application of mixed refrigerants [PDF]

open access: yes, 1978
A critical review of U.S. and foreign literature on the use of a mixture of refrigerants rather than a single one in a refrigeration unit indicates that energy can be conserved in properly arranged systems. An independent analytical study performed under the current contract using a 50% mixture of R-12 and R-114 in a two-evaporator refrigerator typical

Synergistic Sunlight‐Activated Photodynamic and Near‐Infrared‐Induced Mild Photothermal Therapy for Infected Wound Healing Using Functionalized Nano‐Bi2WO6 Composites

open access: yesAdvanced Science, EarlyView.
This work proposes a multifunctional Bi2WO6:Yb,Er@CuS@CS nanocomposite that integrates photodynamic therapy (PDT), near‐infrared‐triggered photothermal therapy (PTT), and Cu2+ release for infected wound repair. The nanocomposite demonstrates enhanced antibacterial efficacy via combined PDT, PTT, and Cu2+ release, effective immunomodulatory by mild ...

A Nanobody‐LNP Platform for Targeting and Relicensing Dendritic Cells for Potent Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
Plastin‐2 (PLS2) is identified as a dual‐function receptor on DCs that mediates both nanoparticle uptake and immunomodulation. A nanobody‐LNP platform is engineered to integrate antigen delivery with relicensing DCs. The therapeutic strategy elicits potent anti‐tumor T cell responses and leads to significant inhibition of established tumors in vivo ...

The Faraday Scalpel: Electrochemical Nerve Lesioning Mechanisms Studied in Invertebrate Models

open access: yesAdvanced Science, EarlyView.
Direct‐current produces nerve lesioning through discrete electrochemical reactions. Using hypoxia‐sensitive locust nerves and hypoxia‐tolerant leech nerves, we map three injury pathways: cathodic oxygen reduction, cathodic alkalization, and anodic chloride oxidation. These findings establish electrochemical lesioning—the “Faraday Scalpel”—as a precise,
