Orientational dependence of the IR absorbing amide bands of silk is demonstrated from two orthogonal longitudinal and transverse microtome slices with a thickness of only ∼100 nm. Scanning near-field optical microscopy (SNOM) which preferentially probes orientation perpendicular to the sample’s surface was used. Spatial resolution of the silk−epoxy boundary was &#876... https://www.kaliboat.com/product-category/food-servicecommercial-kitchen-equipmentfood-preparation-equipmentcommercial-bread/
