For irradiation, a 1.5 cm build-up layer of a Phantom (Bolusil®, Kerjean Biotechnologies, Aubergenville, France) was placed under the bottom of the flask and fixed with elastic grips to achieve a stable dose distribution of the cell layer attached to the bottom of the flask.
It is a well-known fact that build-up layers form in the interface, but little attention has been given to the very first layer that adheres to the tool surface.
The plating of electroless Ni/Au used as a solderability preservative on top of sequential build-up layers is investigated.
By doing this repeatedly, a build-up of layers can be formed to any desired thickness, usually between 3 6 mm.
Apart from evidencing the observations from the MA-XRF scans, the cross-section revealed a build-up of five layers, indicated with numbers 1-5 in Fig. 4c.
Nanofluid boiling also results in a build-up of a porous layer of nanoparticles on the heater surface.
These structure form from a build-up of very thin layers, produced by microbial communities as they trap and bind sediment or cause carbonate to be deposited from surrounding water.
"So, as in 3D printing, a structure is built up layer by layer into the desired shape, but these new materials are able to transform themselves from one shape into another, much like a child's Transformer toy," wrote the team in a release.
Hardness measurements indicated a higher hardness for the built up layer which is attributable to the finer microstructure of the coating.
Those super-short sentences emphasise certainty and determination, but build up layer by layer towards a climax with a kind of emotional logic.
In this way, a complex 3-D cavity can be built up layer by layer.
