Pattern delineation method and product so produced
TLDR
In this paper, a process for the fabrication of a supported iron oxide pattern involves electromagnetic wave irradiation of a blank, which results in insolubilization so that delineation is accomplished by immersing the processed blank in a suitable solvent.Abstract:
A process for the fabrication of a supported iron oxide pattern involves electromagnetic wave irradiation of a blank. The blank consists of a layer of iron oxide which is soluble in, for example, an acid medium. Irradiation results in insolubilization so that delineation is accomplished by immersing the processed blank in a suitable solvent.read more

Method of manufacturing lightweight thermo-barrier material
TL;DR: In this paper, a method of manufacturing thermal barrier structures comprising at least three inner dimpled cores separated by flat plate material and having outer surfaces of the flat plate materials, all elements being joined together by liquid interface diffusion (LID) bonding is presented.
Patent
Method for adjusting the focus and power of a trimming laser
TL;DR: In this article, a laser is used to cut slots into a film deposited on a substrate so that a clean kerf is produced without harming the substrate, and the laser cut vaporizes the film material as the removal mechanism and some of the vaporized material will redeposit over the surface of the film adjacent to the kerf.

Synthesis of iron enneacarbonyl
TL;DR: In this article, the authors describe a continuous process by irradiation of pure Fe(CO) 5 at a temperature less than 20‹ C. The light used has a wavelength greater than 400 mA to avoid rapid deposition of product on the walls of the reaction vessel halting the reaction, and less than 700 mA, to reduce the optical path length necessary for total absorption of light.
