Abstract The solid-state NMR has been used to investigate insoluble materials in advanced industrial site. It could be applied to a broad range of organic/inorganic nano-materials including polymers and bio-solids including pharmaceutical drugs and membrane proteins. Solid-state NMR spectroscopy is very valuable to study the structure and dynamics of membrane proteins even though most biological samples on lipid bilayers have high dielectric property due to containing large amounts of lipids, water and salts. We try to make the specific probe with high efficiency and durability for biological samples. Here, we present the optimized design, construction, and efficiency of a home-built 400 MHz wide-bore(WB) & narrow bore(NB) 1H-15N solid-state NMR probe and a home-built 800 MHz narrow-bore(NB) 1H-15N solid-state NMR probe for these lossy membrane proteins. Li-ion battery and LCD panel have been grown up rapidly as a front-runner in technology-intensive industry. Their microstructural changes are the reason of battery efficiency drop and defective pixel. We will also present a home-built 500 MHz NB 19F-13C solid-state NMR probe with flat-square coil for analyzing LCD panel and 600 MHz NB 19F-7Li solid-state NMR probe with solenoidal coil for investigating Li-ion battery. These were the first application for the in-situ analysis of LCD panel and in-situ analysis of Li ion batterypack samples. These two probes provide high efficiency and good RF homogeneity.
