Food Science and Human Wellness 2024年

作者： Feng Yang Haijuan Hu yingying Li Shilei Li Wenting Liu yu Qi Shouwei Wang China Meat Research Center Beijing Institute of Food Science

Cell cultured meat has been extensively studied as an environmentally friendly， energy-saving and more effective technology. However， there are many technical bottlenecks， especially the regulatory mechanism and manufacturing method of in vitro myogenesis. Based on an edible modified silk protein scaffold， with 3D culturing， in situ differentiated and transcriptome analysis， this study describes novel scaffolds and fabrication methods for cell cultured meat. The results showed that the effective space and utilization efficiency for cell culture of the scaffold is 26-1000 that of the traditional culture dish; it could form a tissue-like structure. Transcriptomics revealed the regulatory pathways and key factors of different cycles. It clarifies that the multi-cycle process of myoblast myogenesis in vitro is different from the single feedback regulation in vivo. More importantly， a novel scaffold-based cell cultured meat manufacturing method was developed， further develop a new tissue culture solution that is different from existing cell culture meat *** manufacturing processes， it provides a new cell culture meat technology system， provides a theoretical basis for the regulation of cell proliferation and muscle growth， and lays the technical foundation for in situ tissue culture of cell cultured meat in vitro.

竖直微槽群毛细结构广泛应用在重力热管、蒸发器等散热设备内,但受重力等因素影响易达到毛细极限。引入电场的主动强化方式来提高竖直微槽的毛细极限,并通过实验和建立数学模型研究电场对竖直微槽内液体润湿及毛细流动特性的影响。结果表明,电场可以提高竖直微槽内液体润湿高度,当电场为5.0 kV时与无电场时相比,润湿高度强化比可达到30.0%。同时,电场作用下流体在微槽道内的毛细润湿流动呈分段效应:润湿流动初期,润湿高度与时间的1/2次方呈线性关系,即h-t^(1/2),润湿速率与润湿高度的倒数呈线性关系,即v-1/h;润湿流动中后期,润湿高度与时间的1/3次方呈线性关系,即h-t^(1/3),润湿速率与润湿高度平方的倒数呈线性关系,即v-1/h^(2),且润湿速率随时间呈下降趋势。

传统微槽群散热器(TMHS)因散热能力强、无功耗等优点,在LED散热领域广泛应用。然而,TMHS与LED光源基板之间需热界面材料填充,导致产生界面热阻,影响散热效果。为消除界面热阻,提高TMHS散热性能,实现大功率LED散热器小体积、轻量化,本文提出在LED光源基板上加工微槽,并将其与TMHS微槽取热表面设计成一体化器件,形成光热一体化微槽群散热器(PIMHS)。实验表明,PIMHS具有良好的散热能力、均温性能、光学参数以及可靠性。LED光源输入功率500 W时,PIMHS与TMHS相比,热阻下降4.5倍,LED光源表面温度下降30.34%,光效提升28.8%。并且,PIMHS可实现kW级LED光源散热,横向、纵向温差均小于1℃。
