The emulsions with nano-sized dispersed phase is called nanoemulsions having a wide variety of applications ranging from food, dairy, pharmaceutics to paint and oil industries. As one of the high energy consumer methods, ultrasonic emulsification (UE) are being utilized in many processes providing unique benefits and advantages. In the present review, ultrasonic nano-emulsification is critically reviewed and assessed by focusing on the main parameters such pre-emulsion processes, multi-frequency or multi-step irradiations and also surfactant-free parameters. Furthermore, categorizing aposematic data of experimental researches such as frequency, irradiation power and time, oil phase and surfactant concentration and also droplet size and stability duration are analyzed and conceded in tables being beneficial to indicate uncovered fields. It is believed that the UE with optimized parameters and stimulated conditions is a developing method with various advantages.

具有纳米级分散相的乳液称为纳米乳液，具有从食品，乳制品，制药到油漆和石油工业的广泛应用。作为高能耗的方法之一，超声乳化（UE）在许多过程中得到了利用，具有独特的优势和优势。在本综述中，超声纳米乳化通过重点关注主要参数（如预乳化工艺，多频或多步辐照以及不含表面活性剂的参数）进行了严格的审查和评估。此外，在表中分析并归纳了实验研究的归类数据，如频率，辐照功率和时间，油相和表面活性剂浓度，以及液滴的大小和稳定时间，这有利于指示未发现的领域。
