纳米结构对溶胶-凝胶衍生的Ce0.9Gd0.1O2（CGO）的电性能的影响在O-2中从350到600 ℃进行评估。CGO气凝胶中< 10 nm微晶之间建立的高度互连性（见图）产生了一种电瓷，其响应就像它不含晶界一样，并且表现出离子扩散的长程路径（约100 nm）。0.5 mm）。
The impact of nanoarchitecture on the electrical properties of sol-gel-derived Ce0.9Gd0.1O2 (CGO) is evaluated in O-2 from 350 to 600 degrees C. The high degree of interconnectivity established between the < 10 nm crystallites in CGO aerogels (see figure) yields an electroceramic that responds as though it contains no grain boundaries and which exhibits long-range pathways for ionic diffusion (ca. 0.5 mm).
