Single particle studies of deliquesced aerosols: multiphase reactions and surface tension
Atmospheric particulate matter or aerosol particles, directly and indirectly, impact climate, regional air quality, and human health. The impacts are closely associated with aerosol particles' chemical and physical evolution, which can be regulated by multiphase reactions and surface tension of deliquesced aerosol particles, respectively. However, in the extreme environment of aerosol particles, the behavior of the reaction kinetics and surface tension often deviates from our chemical intuition based on a beaker-scale understanding. My talk will introduce spectroscopic methods for single particle analysis to study reaction kinetics and surface tension of aerosol particles. The methods are based on inelastic (Raman) and quasi-elastic light scattering (QELS) techniques. Raman and QELS techniques will show dramatic differences in reaction kinetics and surface tension of deliquesced aerosol particles from beaker-scale (bulk) solutions. Our laboratory study would be helpful to improve our understanding of aerosol chemistry with broad implications for air quality and climate.

Fabrication of nanocomposite materials prepared by gas-phase methods for photocatalytic applications
Organic waste derived from the textile industry is toxic and dangerous to humans and the ecosystem. Photodegradation of the organic pollutant by catalyst derived from semiconductor materials is one of the promising methods. TiO2 or ZnO is one of the semiconductive materials that during illumination acts as a strong oxidizing agent lowering the activation energy for the decomposition of organic compounds. However, the photocatalytic activity of TiO2/ZnO is inhibited by the recombination of the photogenerated electron-hole pairs. The objective of this study is to fabricate the binary nanocomposite materials (TiO2/ZnO-Ag) using the gas-phase methods via aerosol routes. Plasma-enhanced chemical vapor deposition, flame pyrolysis, and spray pyrolysis methods were used to synthesize the nanocomposite materials. The results showed that the addition of Ag nanoparticles enhanced the photocatalytic performance up to optimum conditions.
Soot as an Electrocatalyst Support for Enhanced Ethanol Oxidation in Fuel Cells

Capitalizing on soot’s exceptional surface area and conductivity, researchers have developed a cost-efficient catalyst system that significantly improves electron transfer and enhances overall fuel cell stability. The session will discuss the unique physicochemical properties of soot, advanced synthesis techniques, and its synergistic interaction with catalytic activity. Participants will gain valuable insights into how repurposing waste materials like soot can drive the next generation of fuel cell technologies, fostering more sustainable and economically viable energy solutions.

Sustainable Nanomaterial Design and Applications
The topic on Sustainable Nanomaterial Design and Applications delves into the creation of nanomaterials engineered for sustainable applications in environmental, biomedical, pharmaceutical and agricultural sectors. The content emphasizes advancements in nanomaterials design and technologies. The presentation explores ways to achieve resource efficiency and minimize waste. Key applications include innovations in drug delivery, water purification, and seed enhancement, illustrating the impactful role of sustainable nanomaterial design in addressing global environmental challenges and advancing a circular economy across various industries.
The role of heat transfer in food processing towards a healthier lifestyle and cancer-free food consumption
Food processing requires controllable heat transfer to optimize food production costs. Uncontrollable heat transfer also affects the food properties and the left-over medium that is used to cook the food. For example, the excess heat and crust in cooking oil contribute to oil degradation, shortening the cooking oil life cycle and significantly impacting 3 out of 17 Sustainable Development Goals (SDGs). Improper heat transfer in the frying process ruins the food product, contributing to a high GI index and acrylamide formation, a potential occupational carcinogen compound that spontaneously occurs in high-protein food and sugar. Our recent work focuses on heat and mass transfer in fried food, which is responsible for producing good food that is safely consumed by consumers worldwide.

Nano-Based Antifeedant : Tithonia diversifolia Leaf Extract Nanosuspension for Controling Cabbage Pest Insect Crocidolomia pavonana Larvae
​​​
​​
The leaf extract of Tithonia diversifolia is effective in deterring Lepidoptera pests like Crocidolomia pavonana larvae. This study reformulates crude extracts into nano-based biopesticides using a low-energy inversion emulsion process, producing a nanodroplet emulsion. The t3 formulation, with a 8:1:1 ratio (Water: Tween 80: Organic suspension), exhibited the smallest droplet size (23.6 ± 39.6 nm) and enhanced wettability (contact angle: 49.4°), improving antifeedant distribution. The t3 formulation had the highest antifeedant activity (74.27%). Dispersing the extract into nanosized droplets with Tween 80 significantly boosts its antifeedant properties.

Facile Synthesis of Vaterite Fine Powder CaCO3 from Padalarang Natural Limestone with HCl-Assisted Fine-Bubble Carbonation
​
​
Vaterite-phase calcium carbonite is particularly valuable for dental applications, due to its spherical structure, non-toxic nature, biocompatibility, and high porosity. However, its metastability makes it more challenging to synthesize consistently compared to calcite and aragonite. This study aimed to synthesize CaCO3 from natural limestone from Padalarang, West Java, Indonesia, using a fine-bubble carbonation method, varying HCl concentrations to assess pH’s influence on vaterite formation. Results indicated that HCl concentration affected both particle size and the calcite-vaterite ratio, with Z-average particle sizes ranging from 114.8 to 118.2 nm, and the highest vaterite content (93 %) observed at 0.04 M HCl.

Quantitative Ecophysiology of Plants: Transport Phenomena
​
​
​My research continue to focus on transport phenomena in plants, encompassing not only particles but also gases. One of my interests is to elucidate the mechanisms of stomatal conductance, specifically how stomata take up water vapor and CO₂. I am also interested in measuring the evaporation rate and vapor pressure deficit in plants, which correlates with transpiration efficiency for water uptake.
Additionally, I plan to study intrinsic water use efficiency in conjunction with net photosynthetic rate. Overall, the study of transport phenomena remains a key interest of mine, particularly in the context of plants and ecosystems on a broader scale.
