The disclosure provides a method for preparing a cross-section of a sample by milling with a focused ion beam. The cross-section is to be prepared at a pre-defined position. The method includes excavating a trench by milling in a first milling direction. The first milling direction leads away from the position of the cross-section to be prepared. The method also includes excavating the cross-section by enlarging the trench by milling in the reversed milling direction. The second milling direction leads towards the position of the cross-section to be prepared, whereupon the milling is completed at the position where the cross-section is to be cut. The desired largest milling depth is achieved at the completion of this milling step.

A method for producing an electrical component is provided. The method includes steps of providing a continuous strip material and separating a section from the continuous strip material using an electron beam.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. Systems, methods and equipment are described for upgrading process streams using electrodialysis or electrodialysis reversal.

Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, novel systems, methods and equipment for conveying and/or cooling treated biomass are described.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) or other materials are processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and/or lignocellulosic materials, in a vault in which the walls and optionally the ceiling include discrete units. Such vaults are re-configurable.

A method for irradiating a planning target volume with charged particles includes delivering the charged particles to the planning target volume with a charged particle therapy system including a charged particle beam path and a gantry configured to rotate about the planning target volume and to direct the charged particle beam path; rotating the gantry, during an irradiation session, to a plurality of positions; during the rotation, irradiating the planning target volume with the charged particles at a first energy level at one or more of the plurality of positions.
