| 5 November | 6:00am – 7:00am | Photovoltaics for Indoor Energy Harvesting The Internet of Things demands a low-cost, stable, and efficient power source for autonomous smart devices and sensors in low-light environments. Indoor photovoltaics (PV) meets this need, offering grid independence, portability, and sustainability. Amorphous silicon is preferred over polycrystalline for indoor commercial use due to its higher efficiency under low-intensity lighting. Recent advancements in all technologies, from silicon, to compound semiconductors, to emerging technologies such as organic, dye-sensitized PV cells, will be reviewed highlighting the differences between designing and operation of PV cells meant for outdoors vs those for indoors. We will focus more significantly on the development of perovskite solar cells that have pushed indoor PV efficiency beyond the 30% range, also on flexible substrates which are conducive to more seamless integration in indoor products, bringing to the fore challenges, and potential applications for this technology. |

| 5 November | 7:00am – 8:00am | Biomass – A Bit of Science, Technology and Policy Interest in biomass as a cleaner alternative to fossil fuels waxes and wanes. What has remained constant is the extensive use of some form of biomass (forest residue, nut shells, cow dung etc.) as fuel for cooking and heating in developing nations. Usually such use is very inefficient and given the magnitude of consumption, improving efficiency can lead to not-so-insignificant reduction in greenhouse gas emissions. This is particularly true if the alternative is to provide LPG or CNG to these users. Of course, the benefits in terms of the health of women and children with the improved stoves is much more significant. We will discuss a case of development and dissemination of one such clean cooking device in India. Though the case of improved stoves hold the potential for global impact, interventions have been restricted to niche areas (parts of India, Africa etc.). Large scale biomass utilization for energy, fuels and chemicals is challenging due to the distributed nature of the resource. Supply chain is a major challenge in scale-up and commercialization. There are niche applications with excellent supply chains that are exceptions – for instance, the coconut shell charcoal business in South India, Sri Lanka and Philippines. Here again, traditional processes are inefficient and polluting and there is a need for clean alternatives. I will briefly discuss an innovation from our lab known as the susstains process for clean biochar and activated carbon synthesis from biomass and our work on commercialization of these technologies. Hydrogen from biomass is another exciting avenue with applications is decarbonization of cement, steel and chemical sectors. But for this process to have significant impact, issues of supply chain must be overcome. We have been developing a process for biomass to hydrogen through thermo-chemical conversion and attempting scale-up. Finally, I will bring up questions of availability, policy etc. for discussion. |

| 6 November | 7:00am – 8:00am | Creating a New Circular Carbon Economy via Carbon Capture, Utilization and Storage To meet the ever-increasing global energy demands while addressing climate change, the development of carbon capture, utilization and storage (CCUS) technologies is one of the critical needs. In particular, there have been significant efforts to develop innovative CO2 capture materials and CO2 conversion technologies to create a new circular carbon economy based on renewable energy. The next-generation CO2 capture materials, which are often water-free or water-lean, have unique structural and chemical properties that allow their applications in a wide range of reactive separation systems. Nanoparticle Organic Hybrid Materials (NOHMs) are organic-inorganic hybrids that consist of a hard nanoparticle core functionalized with a molecular organic corona that possesses a high degree of chemical and physical tunability. It has recently been discovered that NOHMs have interesting electrolyte properties that allow the CO2 capture to be pulled by the in-situ CO2 conversion reactions. The development of these unique nanoscale hybrid materials will not only advance CO2 capture materials design but also introduce unique research opportunities in various sustainable energy and environmental fields. This seminar will discuss the challenges and opportunities of different CO2 capture and conversion pathways including Negative Emission Technologies (e.g., Direct Air Capture) that can allow the development of circular carbon and hydrogen economy using renewable energy. |

| 4 December | 7:00am – 8:00am | Developing Safer Materials Using Dow’s Smart Search, Powered by CAS Anthraquinone (AQ) is used as a digester aid in the Kraft process, to help break down lignin and release cellulose (pulp). The use of AQ is under scrutiny because it is a suspected carcinogen, and its use is being phased-out in many geographies. In order to develop an alternative potential digester aid, we developed a digital workflow that identifies molecules with the desired toxicity profile, price, and solubility. Coupled with a technical hypothesis around electron affinity screen, a predictor for catalytic activity was developed. This workflow enabled the prioritization of 30 molecules from millions of commercially available molecules. The efficiency of these candidates has been explored in pulp & paper process with several materials showing similar efficacy as that of the incumbent (AQ), and are more ecofriendly. Efforts have been directed towards broadly deploying the use of this digital tool (database and workflows) across various projects within Dow by deploying it in Scifindern. This tool was awarded Edison Gold Award in 2023. This smart and digital approach could help accelerate safer material discovery for faster implementation of potential solutions. |
