ABSTRACT
OBJECTIVES: Burn patients are reportedly prone to complications, such as skeletal muscle wasting, anemia, and slow wound healing, during treatment, due to disease and metabolic depletion, which affect prognosis. Nutritional support is essential in treating burns and can significantly improve patient survival and reduce complications such as infection. This study aimed to perform a bibliometric analysis of the existing literature on nutritional support for burns and to explore possible future research trends. METHODS: The literature related to nutritional support for burns from 1983 to 2022 was searched on Web of Science. The included literature was used for bibliometric analysis using VOSviewer and CiteSpace software. RESULTS: There were 260 publications on nutritional support for burns. The United States contributes significantly to research in this area. The United States has the highest number of publications (n = 119) and citations (n = 4424). Nutrition support was the keyword with strongest burst intensity. A diet of ≥ 60% carbohydrates and 12% to 15% fat is suitable for burn patients, but the optimal ratios have not been fully determined. CONCLUSIONS: An optimal nutritional support program is essential for treating burn patients. Individualized nutritional support programs are the trend in this field. At present, more rigorous multicenter prospective studies with large samples are needed to explore the optimal ratios for specific dietary programs, especially macronutrients, to achieve satisfactory nutritional support and improve patient prognosis.

Polymer composites with electrically conductive fillers have been developed as mechanically flexible, easily processable electromagnetic interference (EMI) shielding materials. Although there are a few elastomeric composites with nanostructured silvers and carbon nanotubes showing moderate stretchability, their EMI shielding effectiveness (SE) deteriorates consistently with stretching. Here, a highly stretchable polymer composite embedded with a three-dimensional (3D) liquid-metal (LM) network exhibiting substantial increases of EMI SE when stretched is reported, which matches the EMI SE of metallic plates over an exceptionally broad frequency range of 2.65-40 GHz. The electrical conductivities achieved in the 3D LM composite are among the state-of-the-art in stretchable conductors under large mechanical deformations. With skin-like elastic compliance and toughness, the material provides a route to meet the demands for emerging soft and human-friendly electronics.
ABSTRACT
Thin and flexible materials that can provide efficient electromagnetic interference (EMI) shielding are urgently needed, especially if they can be easily processed and withstand harsh environments. Herein, layer-structured Fe-Si-B/Ni-Cu-P metallic glass composites have been developed by simple electroless plating Ni-Cu-P coating on commercial Fe-Si-B metallic glasses. The 0.1 mm-thick composite shows EMI shielding effectiveness of 40 dB over the X-band frequency range, which is higher than those of traditional metals, metal oxides, and their polymer composites of larger thickness. Most of the applied electromagnetic waves are proved to be absorbed rather than bounced back. This performance originates from the combination of a superior soft magnetic property, excellent electrical conductivity, and multiple internal reflections from multilayer composites. In addition, the flexible composites also exhibit good corrosion resistance, high thermal stability, and excellent tensile strength, making them suitable for EMI shielding in harsh chemical or thermal environments.
