Dae-Yoon Kim et al.
Soft matter, 11(1), 58-68 (2014-11-20)
Unconventional star-shaped liquid crystals (abbreviated as SiLCs) were successfully synthesized by chemically connecting four cyanobiphenyl anisotropic mesogens to the periphery of a super-hydrophobic and ultra-flexible cyclic tetramethyltetrasiloxane ring with flexible hexyl chains. Based on the combined experimental techniques of differential

FePt Nanogranular films for high density heat-assisted magnetic recording

A hard disk drive (HDD) is a data storage device that stores digital information by magnetizing nanosized magnets on flat disks and retrieves data by sensing the resulting magnetic field.

Recent Progress in Spintronic Materials

Spin-based electronic (spintronic) devices offer significant improvement to the limits of conventional charge-based memory and logic devices which suffer from high power usage, leakage current, performance saturation, and device complexity.
