Bigger Picture Talks

See the bigger picture, join the discussion

Our departmental seminar series, Bigger Picture Talks, runs throughout the academic year, inviting thought-leaders from across the world driving significant advances in our impact areas of energy, health and sustainability to share and discuss their work with us. This is a fantastic opportunity for us to hear from other leading researchers, develop new connections and collaborations, and discuss some of the wider questions in our field. We hope they will inspire new ideas for us all to take into our own research.

The seminars are predominantly for an internal audience, but are often open to all members of the University of Cambridge, and sometimes wider. We endeavour to open the events to as wide an audience as possible, and will share recordings where we are able, but due to the nature of research talks, they often feature pre-publication results, so this is not always possible. You can find our upcoming seminars on our talks.cam listings, and see our previous speakers below.

*Bigger Picture Talks is a series of seminars organised by Dr Ewa Marek, on behalf of the CEB Research Committee, and held at the department during term time. Dr Marek is always keen to hear from interested parties with feedback and suggestions for future talks.

2024/25 Series

13 November 2024

Dr Adelina Voutchkova-Kostal

Director of Sustainable Development at the American Chemical Society
Alcohols to Sustainable Aviation Fuel Mixture via Multifunctional Catalysis

A promising approach for the economic production of drop-in fuel substitutes, such as sustainable aviation fuels (SAF), is the use of hydrogen-free processes driven by multifunctional catalysts. Our research focuses on alcohol upgrading and deoxygenation cascades that yield only water, hydrogen, and carbon monoxide. This hydrogen-free process is catalyzed by multifunctional Pd catalysts, supported on materials with varied acid-base properties: primarily basic MgO, acidic γ-Al₂O₃, and Mg-Al hydrotalcite (HT), which offers a balance of Lewis acidic and basic sites. This process is currently being developed for aviation applications.

In the second part of the talk, Dr. Voutchkova will explore how the ACS Green Chemistry Institute is accelerating innovation in green and sustainable chemistry through: (i) fostering knowledge exchange and cross-sector collaboration; (ii) partnering with industry to drive the adoption of green chemistry and develop essential research tools and metrics; and (iii) training the chemistry workforce to create more sustainable processes, chemicals, and materials.

17 October 2024

Dr Agnieszka (Aga) Iwasiewicz-Wabnig FRSA
Director of the Maxwell Centre and Industrial Strategy Lead for the Cambridge Zero initiative
The role of science and technology in delivering a healthy, resilient society by 2051

To create an ideal future society, meaningful, interdisciplinary relationships and knowledge exchange between academic research, industry, and external stakeholders are essential. This talk illustrated how informal conversations over coffee can lead to significant, scalable impacts, emphasising that each of us has a vital role to play, including the courage to speak out when needed.

The new Maxwell Centre strategy, focusing on Zero Waste and Health Tech themes, will be positioned to facilitate these transformative connections and Dr Iwasiewicz-Wabnig discussed how.
