NTS Research and Inc. is a research company dedicated to developing safe and environmentally-friendly pest management solutions. The goal of the company is to develop vegetable oil based bio-pesticide that is non-toxic and environmentally friendly. There have been tremendous efforts globally in developing non-toxic pesticides with minimum risks by using natural materials as pest control substances. Use of bio-pesticides that use vegetable oils such as soybean oil has been approved by Environmental Protection Agency (EPA) and Pest Management Regulatory Agency (PMRA). Use of these vegetable oil based bio-pesticides shows great promise. Formulation of bio-pesticides typically involves dilution and emulsification of oil in water with little or no use of surfactants. Thus, oil is mechanically broken into small droplets through spray or pressure homogenizers in order to emulsify oil in water without the use of chemical emulsifiers. However, one of the main problems with mechanical emulsification is that oil tends to conglomerate into larger droplets over time. NTS Research and Inc. has developed a proprietary bio-pesticide, Oleotrol-M, as well as a mechanical emulsification process to break oil into submicron size droplets, leading to stable emulsification over long time. However, because stable emulsification is performed at the company not at the location of use, Oleotrol-M is currently sold as already diluted pesticide solution, leading to significant increases in shipping cost due to the weight of water used for dilution As NTS develops effective pesticide solutions, cost effective device that can perform easy emulsification of the pesticide oil at the location of use can lead to significant savings in shipping and better marketing of their product, because such device can allow purchase of pesticide only without dilution, which can be done locally afterwards. NTS can also benefit from the sales of such device that can continuously emulsify pesticide oil in the local water. Thus, the objective of this Engage project is to develop a small and cost-effective ultrasonic atomization device that can mechanically create stable emulsification of Oleotrol in water.

NTS Research and Inc.是一家致力于开发安全环保的害虫的研究公司 管理解决方案。该公司的目标是开发基于植物油的生物农药，即 无毒、环保。全球已经做出了巨大的努力来开发无毒的 风险最低的杀虫剂，使用天然材料作为虫害防治物质。使用生物杀虫剂 使用大豆油等植物油已获得环境保护局(EPA)和有害生物组织的批准 管理监管机构(PMRA)。这些植物油类生物农药的使用显示出很好的效果 我保证。生物农药的配方通常包括将油在水中稀释和乳化， 或者不使用表面活性剂。因此，油通过喷雾或压力被机械地分解成小液滴。 为了在不使用化学乳化剂的情况下将水中的油乳化，需要使用均质剂。然而，其中一个 机械乳化的主要问题是，随着时间的推移，油往往会凝聚成更大的液滴。 NTS Research and Inc.开发了一种专利生物杀虫剂Oleotrol-M，以及一种机械 乳化过程将油分解成亚微米大小的液滴，从而实现长期稳定的乳化 时间到了。然而，由于稳定的乳化是在公司而不是在使用地点进行的， Oleotrol-M目前作为已经稀释的杀虫剂溶液出售，导致出货量大幅增加 由于NTS开发有效的农药溶液时用于稀释的水的重量而产生的成本，成本效益高 在使用地点可以容易地对杀虫剂油进行乳化的设备可以导致显著的 节省运费和更好的产品营销，因为这样的设备可以购买杀虫剂 只有在没有稀释的情况下，才能在当地进行稀释。NTS也可以从这种设备的销售中受益 可以持续乳化当地水中的农药油。因此，该接洽项目的目标是 开发一种小型、高性价比的超声波雾化装置，它可以机械地产生稳定的 Oleotrol在水中的乳化
