Dr. David Madden discusses ‘The Age of Digital Chemistry’ and the way his work could make an influence throughout the local weather disaster.
Dr. David Madden obtained his PhD in Bodily Chemistry from the College of Limerick in 2014 finding out the usefulness of porous supplies for fuel separation. He then pursued a postdoc in crystal engineering on the College’s Bernal Institute.
As a researcher, he labored with Prof. Michael Zaworotko and Prof. Gavin Walker on the extension of a metal-organic framework (MOF) for pure fuel purification and CO2 direct air seize know-how. MOFs are crystalline compounds made up of metallic ions sure by natural molecules, which may probably be utilized in areas akin to vitality storage.
Madden centered on creating monolithic MOFs on the College of Cambridge for industrial and environmental functions akin to heating, air flow and air con, carbon seize and automobile gasoline fuel storage. In 2021 he returned to the College of Limerick on a Marie Skłodowska-Curie Fellowship, and in 2022 he obtained a Pathway Fellowship from Science Basis Eire and the Irish Analysis Council.
On this fellowship, he’s researching the digital manufacturing of superior nanoparticle supplies for medical therapy and energy-related functions.
‘I all the time attempt to convey that if there’s a cleaner, extra energy-efficient resolution to the present know-how, it needs to be pursued.’

Please inform us about your present analysis.
At the moment, I’m researching the event of automated manufacturing processes for superior nanoporous supplies.
My analysis combines steady synthesis strategies akin to movement chemistry and mechanochemical twin screw extrusion with course of analytical strategies (PAT) for the managed synthesis of MOF nanoparticles.
PAT is used to judge essential parameters akin to materials high quality and particle measurement, and makes use of machine studying and automatic course of management to tune and optimize synthesis situations to realize MOF nanoparticle synthesis with preferential measurement and form.
Why do you assume your analysis is essential?
We’re getting into an period of digital chemistry, together with the digital fabrication of superior nanoporous supplies. Accordingly, synthetic intelligence and machine studying will play an essential function within the discovery, improvement and manufacturing of the subsequent technology of superior supplies.
The primary excessive floor space nanoporous MOF supplies have been printed in 1999 and we are actually shifting to a degree the place MOFs are beginning to enter pilot and industrial scale use in areas akin to carbon seize, air con, sensor know-how, and medical therapeutics.
Advances in next-generation manufacturing applied sciences for the managed synthesis of MOF nanoparticles will likely be an essential step in the direction of MOF product improvement, together with shaping, densification, and materials integration.
Automated strategies for MOF materials synthesis could pave the best way for future materials discovery, high-throughput chemical synthesis of MOFs, and associated coordination compounds akin to covalent natural frameworks (COFs), coordination cages and perovskites.
What made you turn into a researcher?
I’ve all the time been deeply fascinated by environmental and clear vitality applied sciences. After finishing my bachelor’s diploma, I pursued a grasp’s program in environmental engineering to pursue analysis in tidal vitality know-how.
Sadly, sickness prevented me from finishing the analysis side of my grasp’s program in Belfast, as an alternative finishing it whereas creating supplies for carbon seize know-how at Limerick College. The fabric I have been engaged on since then has demonstrated an incredible capability to selectively seize carbon dioxide, even immediately from the environment.
I discovered the sphere of analysis to be glorious and, given the approaching local weather disaster, I made a decision to work on this discipline for the long run, hoping to be on the forefront of combating catastrophic local weather change.
Within the subsequent 20 years, humanity will face a crucial level by which the urgency to get rid of carbon dioxide emissions requires a fast response within the improvement of fresh vitality applied sciences, and thru which the world will likely be remodeled into the subsequent technology of fresh vitality applied sciences.
This response requires the mobilization of supplies scientists, chemists and engineers in the same method to the COVID-19 response, and I wish to play a pivotal function within the options developed.
What’s the largest problem or misunderstanding you face as a researcher in your discipline?
As a third-generation MOF scientist, I typically face a sure stigma about MOFs by researchers and business relatively than academia. The primary MOFs have been developed in 1999 and regardless of a surge in tutorial analysis and curiosity from the scientific group all over the world, MOF’s preliminary guarantees haven’t been realized.
Industries akin to car producers and chemical giants have invested some huge cash and sources in MOF improvement with restricted returns. Sadly, many supplies within the first decade of MOF analysis weren’t appropriate for changing present applied sciences. For a very long time, MOF has maintained a domineering place in quite a few industries.
Fortunately, recollections of those failures are starting to fade and we are actually seeing the primary MOFs transition from tutorial labs to full-fledged industrial manufacturing and use. Canadian firm Svante lately put in the primary MOF-based pilot facility for carbon seize within the cement business. The success of this has led to a surge in curiosity in MOFs within the wilderness in current practically a decade.
Do you assume public participation in science has modified lately? How do you encourage participation in your work?
As a scientist working in fields associated to local weather change, I’ve typically confronted critical boundaries to public engagement on account of local weather skeptics. Fortunately, public opinion about local weather change and science generally is beginning to change on account of the COVID-19 pandemic.
The pandemic has restored essential scientific beliefs as we reside indefinitely with COVID-19, paving the best way for the world to return to a standard lifestyle via virus and vaccine analysis. I consider that science champions like Professor Luke O’Neill in Eire (with their capability to convey science to strange individuals and a reassuring voice) helped restore belief in science.
By way of my work, I’m all the time completely happy to debate my analysis with the broader public. I all the time attempt to convey that if there’s a cleaner and extra vitality environment friendly resolution to the present know-how, it needs to be pursued. Humanity should attempt for a greater self without end. Even higher if this implies we’ve a cleaner and extra sustainable local weather and lifestyle.
