Abstract In the last decade, organ-on-a-chip technology has been researched as an alternative to animal and cell culture models (Buhidma et al. in NPJ Parkinson’s Dis, 2020; Pearce et al. in Eur Cells Mater 13:1–10, 2007; Huh et al. in Nat Protoc 8:2135–2157, 2013). While extensive research has focused on the biological functions of these chips, there has been limited exploration of functional materials that can accurately replicate the biological environment. Our group concentrated on a lung-on-a-chip featuring a newly fabricated porous silicon bio-membrane. This bio-membrane mimics the interstitial space found between epithelial and endothelial cells in vivo, with a thickness of approximately 1 μm (Ingber in Cell 164:1105–1109, 2016). This study aims to establish a fabrication method for producing a thin, uniform porous silicon membrane with a predictable reduced modulus . We conducted mechanical and morphological characterization using scanning electron microscopy and nanoindentation. A small, parametric study was conducted to determine the reduced modulus of the porous silicon and how it may relate to the morphological features of the membrane. We compare our results to other works. Graphical Abstract
在过去的十年中，器官芯片技术被研究作为动物和细胞培养模型的替代方法(Buhidma et al. In NPJ Parkinson 's Dis, 2020;Pearce et al. journal of chengdu electro - mechaical, 2007;Huh et al. in Nat Protoc 8:2135-2157, 2013)。虽然广泛的研究集中在这些芯片的生物功能上，但对能够准确复制生物环境的功能材料的探索有限。我们的团队专注于一种肺芯片，其特点是一种新制造的多孔硅生物膜。这种生物膜模拟了体内上皮细胞和内皮细胞之间的间隙，厚度约为1 μm (Ingber in Cell 164:1105-1109, 2016)。本研究旨在建立一种制造方法，用于生产具有可预测的降低模量的薄而均匀的多孔硅膜。我们使用扫描电子显微镜和纳米压痕进行了机械和形态表征。一个小的，参数化的研究进行了确定减少的多孔硅的模量，以及它如何可能涉及到膜的形态特征。我们将我们的结果与其他作品进行比较。图形抽象

The ionic conductivity, thermal stability, and general viability for use as electrolytes in fuel cells are examined for two borophosphate polyelectrolyte compounds (e.g., sodium borophosphate (NaBOB, Na5[BOB(PO4)3)]) and ammonium borophosphate (NH4BOB, (NH4)3H2[BOB(PO4)3])). Bulk synthesis methods are presented for laboratory scale reactions (> 5 g) using low-temperature ionic liquid fluxes. Electrochemical impedance spectroscopy (EIS) was used to determine temperature-dependent ionic conductivities of the NH4BOB and NaBOB to be on the order of 2 µS cm−1 and 0.1 µS cm−1 at 200 °C, respectively. Although NH4BOB displays higher ionic conductivity compared to NaBOB at equivalent temperatures, thermal gravimetric analysis (TGA) shows much higher thermal stability for NaBOB, exhibiting no mass loss below 600 °C. The thermal stability of NaBOB was also assessed under reducing (~ 1 atm H2) conditions, finding no reductive thermal degradation below 400 °C. Ab initio molecular dynamics (AIMD) simulations show free proton (H+) movement is related to gyrational mobility of the polyanionic borophosphate chains.

The paper explores the viability of repuposing 18650 lithium-ion cells from consumer electronics at their end of life, collected from local electronics shops in Lagos Nigeria, for second-life application as Battery Energy Storage Systems (BESS). The study also characterizes each cell to determine its residual useful capacity and State of Health (SoH), physical quality, and performance before assembling them into modules and energy storage solutions for off-grid energy systems. The modules built have a capacity of 380 Ah and nominal voltage of 13.7 V, are modular and scalable to nominal voltages. The UL-1974 battery repurposing standards guides the methodology and experimental setup of the study. The cost per kilo watt hour (kWh) and environmental benefits of reusing these batteries are also explored and compared with alternatives. The results show that repurposing 18650 cells reduces waste and environmental impact while providing cost-effective energy storage alternatives to lead acid and first life lithium batteries.
