Time-efficient and inexpensive synthetic routes to manufacture engineered solids and colloidal particles are required by the ever-changing market and applications. The long term objective is to develop ultrasound (ULS)-based techniques to manufacture far-ranging materials, including inorganic, organic, composite and hybrid matrices. I anticipate that modulating the local temperature and pressure, and micro-turbulence enacted by ultrasonic acoustic cavitation will fine-tune the structural-morphological properties of solid and colloidal particles, being these inorganic, organic or hybrid. The sub-objectives include: i) Sonochemical synthesis of catalysts for liquid-solid and gas-solid systems, ii) Sonochemical sol-gel and hydrothermal synthesis of hybrid inorganic-organic frameworks, iii) Sonochemical stabilization of colloidal particles for edible films.

日新月异的市场和应用要求采用既省时又廉价的合成路线来生产工程固体和胶体颗粒。长期目标是开发基于超声波(ULS)的技术来制造远距离材料，包括无机、有机、复合材料和杂化基质。我预计，通过调节局部温度和压力，以及超声波声空化产生的微观湍流，将微调固体和胶体颗粒的结构-形态特性，这些颗粒是无机、有机或混合的。子目标包括：i)液-固和气-固体系催化剂的超声化学合成，ii)超声化学溶胶-凝胶和水热合成杂化无机-有机骨架，iii)可食膜胶体颗粒的超声化学稳定。
