(Nanowerk Information) The proliferation of all issues digital doesn’t imply that printing know-how is now not related. The truth is, printing know-how is required to make the semiconductors mandatory for the digital world. And as an Osaka Metropolitan College-led staff has proven utilizing a brand new printing approach, printable magnetic gadgets for high-density information storage would possibly quickly be realized.

Dr. Ken-ichi Yuyama, a lecturer on the Graduate Faculty of Science, and his colleagues report in APL Supplies (“Using optical vortex laser induced forward transfer to fabricate a twisted ferrite microcrystal array”) on the event of a brand new kind of laser-induced ahead switch (LIFT) for laser printing utilizing an optical vortex, which has been dubbed OV-LIFT.

The staff shined a laser beam on a spatial gentle modulator and thru a quarter-wave plate to transform the beam right into a circularly polarized optical vortex. This beam was then centered onto a plate with magnetic ferrite nanoparticles that had been proven to efficiently be printed on a floor at excessive precision.

The ensuing printed crystals even have helix-like twisted constructions, the path of which could possibly be managed by altering the optical vortex’s helicity to the other rotation.

“The results of this research have the potential to be used not only for fine particle patterning but also for single crystal synthesis, which can be expected to lead to the development of new materials,” declared Dr. Yuyama. “We plan to apply this technology to various types of fine particles, as well as to shine a light on the formation mechanism and function of twisted crystals.”
