Abstract：maybe problematic and their emissions need to be controlled (6). The intentionally producAerosols, particles that are suspended in a gaseous medium, are ubiquitous and found in nature and engineered systems. They occur in a range of sizes, shapes and compositions and are relevant to important phenomena such as climate change, human health, environmental and energy processes. These particles are both inadvertently and intentionally produced in a variety of systems (1). The inadvertently produced particles ed particles have applications in a variety of fields, and form the backbone of the field of nanotechnology. The presentation will describe an understanding of the formation of these particles in gas-phase processes (2, 3), and report on recent scientific advances. The focus will be on the measurement of the sub-nanometer size particles to highlight the important pathways of early stages of particle formation (2). A description of aerosol science and engineering that enables fundamental studies both mechanistically, and by the availability of well controlled particles to understand property-function relationships will be presented. The second part of the talk will focus on aerosol science and engineering enabling a variety of applications. In air quality studies, the development of low cost PM sensors that operate in a wireless modality will be described. In energy systems, the synthesis of novel light harvesting devices (1) to both produce electricity and promote chemistry (reduction of carbon dioxide) (8) will be discussed. The use of aerosol science principles to guide the synthesis of novel materials with strictly controlled characteristics for cancer treatment will be elucidated (5). Finally, approaches to produce efficient fertilizers that are delivered by innovative aerosol techniques will be described that promote smart agriculture reducing the adverse environmental consequences of excessive fertilizer use (4, 7).
