Atomic Layer Deposition on Particulate Materials from 1988 through 2023: A Quantitative Review of Technologies, Materials, and Applications
Atomic layer deposition (ALD) is widely studied for numerous applications and is commercially employed in the semiconductor industry, where planar substrates are the norm. However, the inherent ALD feature of coating virtually any surface geometry with atomistic thickness control is equally attractive for coating particulate materials (supports). In this review, we provide a comprehensive overview of the developments in this decades-old field of ALD on particulate materials, drawing on a bottom-up and quantitative analysis of 799 articles from this field. The obtained dataset is the basis for abstractions regarding reactor types (specifically for particles), coating materials, reactants, supports and processing conditions. Furthermore, the dataset enables direct access to specific processing conditions (for a given material, surface functionality, application etc.) and increases accessibility of the respective literature. We also review fundamental concepts of ALD on particles and discuss the most common applications, i.e., catalysis (thermo-, electro-, photo-), batteries, luminescent phosphors and healthcare. Finally, we identify historical trends and provide an outlook on prospective developments.

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.

😯 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.

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!
