@article { , title = {Oil Powders and Gels from Particle-Stabilized Emulsions}, abstract = {We report on the use of silica particle-stabilized oil-in-water emulsions as a template for the preparation of oil powders and gels obtained in a single step by either slow or rapid evaporation of water using freeze-drying or spray-drying, respectively. Using olive oil and partially hydrophobic fumed silica nanoparticles, an oil powder containing nearly 90 wt \% oil can be formed by spray-drying, which shows no sign of oil leakage over several months. Upon slow evaporation of water by freeze-drying, a transparent oil gel with oil content as high as 98 wt \% can be formed, in which the silica particles form a space-filling network thickening the oil. Comparisons are made throughout with a typical surfactant-stabilized emulsion which does not produce oil powders or gels.}, doi = {10.1021/la204811c}, eissn = {1520-5827}, issn = {0743-7463}, issue = {3}, journal = {LANGMUIR}, note = {Batch 007.
