Cor-ten is a high strength, low alloy, weldable structural steel possessing excellent weathering resistance. It may be used to advantage in painted or unpainted condition. The steel owes its weathering resistance to the formation of a protective oxide coating which seals the surface against further corrosion.
2 core-in-double-shell hollow spheres via hard tem-plating.[28] Alternating SiO 2@PMMA tetra- and penta-layered hybrid spheres are first prepared by combining the sol–gel process and distillation–precipitation polymerization. Etching the SiO 2 from the SiO 2@PMMA@SiO 2@PMMA tetra-layer spheres with HF generates double-shelled PMAA hollow ...

The software automatically adds relief cuts wherever needed when inserting bends if you select Auto Relief. You can edit the bend parameters for a single bend, for a group of bends, or for your entire sheet metal part. The bend parameters include the default bend radius, and the bend allowance or bend deduction values.
Hollow micro-/nanostructures have achieved great success in the field of renewable battery materials by reducing the volume change and promoting the ion transport. Double-shelled Co3V2O8 hollow nanospheres (CVO-DSS) were synthesized using a facile solvothermal method followed by a thermal treatment in the absence of any surfactant. …

There are two paths to assemble hollow spheres into macroporous aggregates, including the hollowing-first method and the assembling-first method. Some troubles might exist in the direct assembly of the open-cell hollow Fe 3 O 4 microspheres into macroporous aggregates because the holes on the shell is probably sealed up by the binder, ...
hollow structures: (1) After forming the targeted shell, template materials could be partially removed, while the remainder becomes the template for generating another shell, leading to

Calling the amount of charge already present q q, the gain in potential energy that comes from adding the shell (which contains an infinitesimal amount of charge we'll call dq d q) is: dU = qdq 4πϵor (2.1.10) (2.1.10) d U = q d q 4 π ϵ o r. Notice that the distance to the center is r r, not R R. This is because the shells that are added are ...
Hollow nanostructures have found applications in catalysis 1, 2, nanoreactor 3, energy storage 4, and drug delivery 5. Despite the progresses in application, the fundamental synthetic capabilities remain at a primitive level. Most hollow nanostructures are enclosed spheres 6 – 9 and to introduce an opening is still a great challenge 10 – 13.
