Welcome to CHoPS 2027 — Delft! The 12th International Conference on Conveying and Handling of Particulate Solids (CHoPS) will be held 6-9 July 2027 in the Aula of Delft University of Technology. In the coming months, abstract submission will be opened. chops27.dryfta.com/registration

"Based on titles and abstracts, in over 80% of cases the LLMs claimed that a retracted article had not been retracted (GPT OSS 120B: 82%; Gemma 3 27B: 84%; DeepSeek R1 72B: 88%)."

What are challenges and enablers in Fluidization Technology? In our latest paper in AIChE J, Jia Wei Chew and I try to answer this. DOI.org/10.1002/aic.70397 What is needed to go from empirical design toward reliable, multi-scale, data-driven fluidization platforms? #ParticleTechnology #ScaleUp #AI

New paper out! Platinum #ALDep egg-shell and uniform distribution coatings through millimeter-sized mesoporous alumina particles. Gonsalves et al., collaboration of @aalto.fi with @jrvo.bsky.social group of TU Delft and others. Great to see this out! doi.org/10.1039/D5LF...

Interested in #ALDep on particles? Read our paper in Chem. Mater. 2026, 38, 1, 20–86. Open access, so everyone can read it! pubs.acs.org/doi/10.1021/... The full dataset is reposited on Zenodo (zenodo.org/records/1796...) & analysis scripts can be forked on GitHub (github.com/P4Science/AL...).

Week-gemiddelde aandeel hernieuwbare stroom. Batterijen kunnen korte variaties overbruggen en wellicht dag-nacht. Voor variaties per week en zeker per maand is iets anders nodig, mede omdat buurlanden hetzelfde weerpatroon hebben. Voorlopig zijn dat gas & kolen. #grafiekvandedag

😯 Artikel dat glyfosaat veilig verklaarde is teruggetrokken. Vijfentwintig jaar lang functioneerde het als een anker voor de stelling dat glyfosaat en Roundup bij regulier gebruik veilig zijn voor de mens. De auteurs bleken echter te zijn ondersteund door Monsanto. www.foodlog.nl/artikel/arti...

BREAKING: The Nobel Prize in Chemistry has been awarded to Susumu Kitagawa, Richard Robson and Omar M. Yaghi “for the development of metal-organic frameworks” Stay tuned for more. #NobelPrize

The Dutch offshore wind programme is in trouble. While 4.5 GW is in operation and another 1.5 GW under construction, the plan was to rapidly build out capacity to 21 GW by 2032. That is now out of reach. My thoughts on how this happened, and what to do about it! www.commonfutures.com/en/insights/...

This week, we had a great #PARTEC2025 symposium on particle techn. Contributions from our team: Hardlife Rambwawasvika on coating particles with #ALDep for controlled release pharma. Rens Kamphorst on modeling agglomeration of nanoparticles. Gabrie Meesters on stickiness. Me on X-ray tomography.

“It was clear to me that the ‘fast-track fee’ was a euphemism for ‘bribe,’” she told us, adding that fast-tracking is “unheard of” in mathematics.

Daring project by my former colleague @maartensta.bsky.social, in his spare time: compiling a European grid capacity (scarcity) map! www.gridcapacitymaps.eu Still a challenge to access the detailed information, due to language and other barriers, but a very useful project indeed.

Air Liquide has taken a final investment decision on a 200MW electrolyser to produce H2 in the Port of Rotterdam, with TotalEnergies as a major client. www.linkedin.com/posts/rotter...

Air Liquide has taken final investment decision on its 200MW green hydrogen project at the Port of Rotterdam, after securing subsidies from the Dutch government. 23,000 tonnes of green hydrogen per year, using electricity from offshore wind. To be operational in 2027. www.h2-view.com/story/air-li...

Een oplossing voor PFAS! Het wordt steeds duidelijker hoeveel PFAS we in ons water hebben en hoe lastig het is om ervan af te komen. Sanne Smith @tudelftceg.bsky.social heeft een oplossing om PFAS met schuim uit water te halen, in bestaande waterzuiveringssystemen. www.tudelft.nl/stories/arti...

Frans Saris is overleden Dirk van Delft schreef in NRC een prachtig in memoriam. Ik sprak hem eens over de vraag of Rechten wel een wetenschappelijke discipline is. Ik overtuigde hem niet en zei: ‘Frans, we heten dan ook Rechtsgeleerdheid’. Hij antwoordde: ‘Ja, geléérd zijn jullie wel!’ #RIP

NEW: NSF will be kicked out of their building. Announcement will be made tomorrow by HUD Sec. and Governor of VA. HUD will take over the NSF building over the next two years. NSF staffer: "There is no planning for NSF, no identified future location, appropriation for a new building or a move."

Sébastien Moitzheim, CTO of @Powall, gave a great talk on continuous production of nanocoated powders at #aldale2025. He showed how to deal with particle mixing & precursor injection. #ALDep at 1bar, not using the high-purity semicon precursors, is a cost-efficient and scalable solution for coating.

I am attending the 2nd International Workshop on Reacting Particle-Gas Systems in Magdeburg. It is hosted by the local university, named after a famous physicist and politician.

🧼"Why does soap make bubbles?" ✍️ “Why can I draw with coloured pencils?” 💥"How does a chemical explosion work?" These are some of the questions that I answered during the Klokhuis questions day held at NEMO Science Museum on Saturday. Such a pleasure to work with these super enthusiastic children!

Een staking van NS-medewerkers in West-Nederland op 10 juni lijkt me niet handig als er al weken een staking van het hoger onderwijs gepland staat op die dag, met een bijeenkomst op het Malieveld... @fvnspoor.bsky.social @woinactie.bsky.social

Great first day of #EuroCVD with several interesting talks: hybrid ALD/MLD, LCA of ALD and CVD processes, novel precursors, etc. We also can’t complain about the venue. #ALDep
