RBFNN Based Linear Motor Cogging Force Identification for Lithography Machines

IFAC-PapersOnLine, 2015
Abstract The cogging force of linear motors significantly affects the positioning accuracy in ultraprecision lithography machines. Optimal motor design cannot completely eliminate it, leaving the realtime active compensation as the only means to counteract its adverse effect.

Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2

Small, EarlyView.
The application of laser pulses, of extremely short duration, is investigated as a potential new method to modify the atomic structure of ultrathin 2D materials for use in the creation of future electrical devices. The process is efficient, offering a site‐specific functionality, where regions of an electronic device that only requires annealing is ...

Cryogenic Infrared Spectroscopy Unmasks Gas‐Phase Charge Migration in Mucin‐Type O‐Glycans

Small, EarlyView.
Protons in a sugar rush: O‐glycans are vital biomolecules, challenging to analyze due to isomeric forms. Using ion mobility spectrometry, cryogenic IR spectroscopy, and ab initio calculations, isomeric O‐glycan cores can be distinguished. At cryogenic temperatures, multiple deprotomers were identified, which interconvert at ambient conditions via rapid

Unlocking Nanoscale Microstructural Detail in Aluminum Alloys Through Differential Phase Contrast Segmentation in STEM

Small Methods, EarlyView.
Differential phase contrast (DPC) imaging in STEM is demonstrated as a rapid, versatile segmentation tool for advanced aluminum alloys. Decomposition of false‐color DPC micrographs resolves nanoclusters, precipitate variants, dislocation strain fields, nanostructures, and grain boundaries ‐ all within a single and fast acquisition.
