“…Hence, decreasing the dispense velocity by one magnitude (from 59.1 to 5.9 µm s −1 ), consequently reduces the initial cross-section of the wet trailing lines according to: A i,vD59.1 = 10 A i,vD5.9 . Similar to the previous study on single droplets, [9] a smaller cross-section lead to an average shorter evaporation time. However, the minimum distance l c that the particles must travel within the timeframe of solvent evaporation to form a CRE stays constant for different v D , as it can be defined as the average distance between two particles in the suspension: [9,26] 4 /3…”

strategies. [4] Here, on-chip microfluidics could aid to effectively remove heat. [4] This requires processing techniques with great design and material flexibility. However, current processes for microfluidics rely mainly on lithography techniques, which are limited in materials selection and restricted to rather 2D designs. [5] Hence, the development of novel processing routes is required that allow design flexible processes such as AM and greater materials variety. [4] Next to thermal management in highpower electronics, thermal shielding in high-temperature applications requires consistent enhancement toward higher working temperatures: here, next-generation reflective thermal barrier coatings (rTBCs) with tailored microstructures have lower thermal conductivity in comparison to traditional TBCs, [6] but most importantly are capable of additionally scatter heat radiation. [7] The emittance of heat radiation scales with temperature by T 4 , hence obstructing radiative heat transport becomes very relevant with increasing working temperatures (>1000 °C). Therefore, coating components for high-temperature applications with such rTBCs could allow the devices to work at higher operating temperatures.

“…In comparison, charged polystyrene opals with carboxylic or amino functionalization assembled on top of the NAA by drop cast [ 172 ] achieve a maximum value of 3.16 W m 2 ; however, with different performances regarding maximum power density depending on the functionalization and structural arrangement of the opals. This interesting result combined with the multitude of processes available to fabricate 3D opal photonic crystal structures, [ 174 ] including recent advances in 3D printing combined with self‐assembly, [ 175 ] and 3D structures of optically relevant metal oxides produced by ALD [ 176–179 ] opens the path for potential future developments in this highly dynamic field. Alternative approaches include changing the electrolyte from acidic to alkaline (i.e., sodium tetraborate) to increase the range of lattice constant (i.e., 250–600 nm) on curved surfaces without oxide burning.…”

Nanoporous anodic alumina (NAA) fabricated by anodization of aluminum is a versatile platform material with tailorable geometric, optical, and chemical features for specific light‐based technologies and applications. Recent advances in anodization technology have enabled a new generation of NAA‐based photonic crystals (PCs)—periodic dielectric nanoporous structures that selectively allow, forbid, and confine the flow of incoming electromagnetic waves of specific wavelengths across their structure. NAA–PCs provide exciting new opportunities to engineer light–matter interactions with versatility across the broad spectrum, from UV to IR. But despite these fundamental advances, demonstrations of sunlight‐harvesting technologies based on NAA–PCs are still limited. Herein, an up‐to‐date summary of recent advances in NAA–PC technology is provided, and proof‐of‐concept demonstrations and future pathways to propel this versatile platform material across sunlight‐harvesting technologies such as photocatalysis, photoelectrocatalysis, photothermal energy conversion, and solar cells are discussed.
