The versatile precursor‐assisted soft sphere close packing during slot‐die coating is investigated with in situ X‐ray scattering. The soft crystallization pathways towards a close packing involve multistep structural transitions such as surface nucleation, in‐plane, and out‐of‐plane crystallization.

Experimental study of endwall flow in a low-speed linear compressor cascade: effect of over-tip leakage [PDF]
This paper describes the study of endwall flow modification due to over-tip leakage flow in axial compressor blades. Un-shrouded axial compressor stator and rotor blades in aero-engines and land based gas turbines are subjected to over-tip leakage flow ...

Wake Mixing in Axial Flow Compressors [PDF]
Over the years it has been speculated that the performance of multi-stage axial flow compressors is enhanced by the passage of a wake through a blade row prior to being mixed-out by viscous diffusion. The link between wake mixing and performance depends on the ability to recover the total pressure deficit of a wake by a reversible flow process.

The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...
