Combustion particle properties and energy-emissions modelling

Top-down and bottom-up approaches to reduce uncertainties in regional air-quality and climate simulations.

Emissions inventory development for research and regulatory applications, in air-quality and climate change, needs explicit linkages to emitting technologies and to the microphysical, chemical and optical properties of emitted particles. The influence of residential solid fuel use on climate over India, through substantial emissions of black carbon particles was first described through work from our laboratory (Venkataraman et al. 2005, Science, 307(5714), 1424-1426). Ongoing research addresses understanding emission aerosol from dispersed tradition combustion sources (residential biomass stoves and kerosene lamps, brick kilns, agricultural field burning) and multi-criteria mitigation analysis to provide decision and policy support.

Simulations of aerosol-induced changes in the radiation balance, clouds and precipitation over India

Spatial distributions of annual emissions of particulate matter (PM2.5) and black carbon (BC) from Indian industrial, transport and residential energy-use.

Understanding the physics of aerosol-mediated atmospheric processes, which influence rainfall is imperative to India’s rain-fed agricultural economy. Mechanisms of alteration of clouds and rainfall by aerosols are being studied through simulations using climate models (ECHAMHAM, WRF-CMAQ/CAMx) and statistical approaches applied to satellite derived cloud and climate variables. This work seeks to improve the physics of climate models to better predict regional climate change.

Aerosol synthesis of nanoparticles with controlled properties for drug delivery applications

Pulse heat aerosol reactor and synthesized lipid nanoparticle mobility size distributions and microstructure (TEM images).

Therapeutic nanoparticles with controlled properties enable control over therapeutic outcomes, through drug targeting to specific sites, enhancing cellular uptake, protection against drug inactivation and achieving controlled drug release. A pulse-heat aerosol reactor has been designed and built to prepare lipid nanoparticles with controlled size, morphology, crystallinity and controlled release properties. Experimental studies investigate nanoparticle surface modification, layered nanoparticles and the encapsulation of drug molecules and genetic material, while modelling studies address mechanisms governing control of nanoparticle properties during droplet drying, to engineer nanoparticles for new applications.
