Upcoming seminars and events 


November 11: Seminar by Nadja A. Simeth, University of Göttingen, Germany

"Tuning the properties of light-responsive molecules to control biohybrid and biological systems." 

Time: 10:15 - 11:30 (ca.)

Place: Ångström laboratory House 7, floor 2.

Abstract

In recent years, light has been employed as an external stimulus to photo-control diverse functional processes. This approach relies on the use of small, light-responsive molecules that undergo a structural change upon irradiation, generating different functional states from a single molecule. By attaching suitable substituents to such photoactuators, these molecules can be embedded in a system of choice to link their structural change to a change in the system’s properties. On the other hand, the sterical and electronic characteristics of the substituents influence the photophysical and photochemical properties of the core. This mutual interaction needs to be finely balanced and studied in detail to rationally design complex systems. Here, we show how optimizing the substituents on different photoactuators allows us to tune several of their properties, such as their UV-Vis absorption profile and photoconversion quantum yield. We will demonstrate how these properties can be employed to achieve both temporal and spectral resolution in a model system.

Previous news and events

Artificial photosynthesis could generate new fossil-free fuels

Today, the vast majority of fuels such as ethanol and hydrogen are produced by fossil fuels using petroleum as a raw material. Artificial photosynthesis captures the sun's light using a technique similar to that used in solar cells, adds water and carbon dioxide, and out comes a fuel in the form of a gas or liquid, such as hydrogen or an alcohol. Two of CAPs researchers, Pia Lindberg (left) and Leif Hammarström (right) were interviewed in October 2022 for a focus story published by Uppsala university.

The CAP workshop, September 27 - 28

The 2022 edition of the CAP workshop at Haga Slott (Enköping) was a great event! More updates about the workshop will be posted soon.

CAP co-organizer of the Energy Theme day on May 19, 2022 

A multidisciplinary theme week took place between 16-20 May on topics in science and technology at the Ångström Laboratory. During this week, current research within AI/Data-driven life science, the Universe and Mathematical Physics, Material, Energy and Climate change was presented by scientists and invited speakers from industry and other parts of society.  

CAP co-organized the session on solar energy and solar fuels  in the afternoon, with the following contributions:

Chairs Marika Edoff and Peter Lindblad.

  • Marika Edoff, Uppsala University, Solve: Solelforskningscentrum Sverige - a new excellence centre.
  • Solar Power in Sweden: Growth and future prospects
  • Per Sundell, Vattenfall: Sustainable aviation fuel from CO2
  • Pietro Campana, Mälardalen University: Combining photovoltaics and agriculture to agrivoltaics - sustainable land sharing
  • Ellen Moons, Karlstad University: Research for efficient and stable new solar cells
  • Leif Hammarström, Uppsala University: Solar fuel, an international overview
  • Pia Lindberg, Uppsala University: Gren cell factories, fuels and chemicals from CO2 and solar energy

New semiconductor coating may pave way for future green fuel

Researchers at Uppsala university have developed a new coating material for semiconductors that may create new opportunities to produce fuels in processes that combine direct sunlight with electricity. The coating is a “metal-organic framework” – a three-dimensional network composed of individual organic molecules that are held in place, on the sub-nanometre scale, by tiny metal connectors. 

“We’ve moved a step closer to our goal of producing the fuel of the future from sunlight,” says Sascha Ott, Professor at the Department of Chemistry, Uppsala University. Read more about this story here.

"In the future, farmers may produce their own fuel"

Johannes Messinger, chair of CAP and Professor at the Department of Chemistry at Uppsala university, is working on a new method for producing fossil-free ammonia (NH3). He was interviewed on October 12, 2021.  

"Ammonia is used in huge amounts and is a key component in the production of fertilisers and various chemicals. What is less well known is that it could also be used for long-term storage of hydrogen and as fuel. We are working on developing an electrochemical method in which nitrogen gas and water are directly combined to form ammonia."

On July 26-29, 2021, CAP co-organized the online International Solar Fuels Conference together with the Royal Society of Chemistry and CNRS Grenoble Alpes, ISF 2021. The conference was visited by leading solar fuels researchers from around the world, and was also preceded by a satellite meeting for young researchers.  To know more, please visit the conference webpage:  International Solar Fuels Conference 2021

SUNERGY Sweden Event

On 20th of April, 2021, 60+ participants joined the SUNERGY online event for Sweden. A dedicated meeting for Sweden that was organized in the run-up to the upcoming calls of the 2021-2022 Horizon Europe work programme and the SUNERGY – CO2 Value Europe joint brokerage event. The meeting was opened by Ann Magnuson,  introducing the SUNERGY vision of enabling a fossil-free Europe through research and innovation. The event emphasized the important role that Sweden can play in this with its strong profile in renewable energy R&D.

"His blue-green bacteria may produce biofuel in the future"

While Peter Lindblad has served in many academic roles over the years, it is to research that he always returns. His research group is developing fuels that could contribute to future energy solutions. “If you want to generate a lot of biomass, you should use a cyanobacteria,” says Peter Lindblad, professor of microbial chemistry.

Soap bubbles on the rise

A research project led by Leif Hammarström at Uppsala University has been awarded a EUR 3.2 million grant by the European Commission. The aim is to create renewable solar fuel using soap foam, carbon dioxide and sunlight. 
SoFiA (Soap Film-based Artificial Photosynthesis) aims to build a small-scale demonstrator device that will be able to produce solar fuels and raw materials for chemical industries using only sunlight, water and CO2. The SoFiA concept mimics the thylakoid membrane in leaves and uses molecular catalysts made from earth abundant materials, to form self-assembled photo catalytic surfaces with designed soap foams.

Haining Tian doubly awarded in 2019 and 2020

Haining Tian was awarded the prestigious Göran Gustafsson Prize in 2020, and also was awarded Wallenberg Academy Fellow in Engineering and Technology 2019, for his work on catalysis and solar fuels.

Read more about Haining at the Knut and Alice Wallenberg Foundation webpage, and on the Tian group webpage.

Shedding new light on greener synthesis pathways

In October 2019, Sascha Ott, Eszter Borbas, Leif Hammarström and Jacinto Sá, received a 5-year grant of 35 million kronor from the Knut and Alice Wallenberg Foundation, for their interdisciplinary project "Unexplored Approaches to Organic Photoredox Catalysis”

In this new research project, the groups will focus on finding new alternatives to several reactions that are widely used in the chemical industry. The objective is to develop new synthesis pathways that generate less waste, or new synthetic routes that previously have been unfeasible.

[Swedish] Nytt solbränsle med hjälp av artificiell fotosyntes - i såpbubblor

Projektet SoFiA (Soap Film-based Artificial Photosynthesis) har som mål att göra en apparat på labskala som producerar solbränslen och råmaterial till kemisk industri med hjälp av enbart solljus, vatten och koldioxid. SoFiA:s koncept härmar tylakoidmembranen hos gröna växter och använder molekylära katalysatorer gjorda av vanliga grundämnen i själv-associerande, foto-katalytiska ytor av designade såpfilmer och skum. Projektet har åtta partnerorganisationer i sex länder och koordineras av professor Leif Hammarström vid Uppsala universitet. SoFiA startade den första januari 2019 och löper under fyra år.
