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.

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.","PeriodicalId":19015,"journal":{"name":"MRS Advances","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135728561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
