DOI: 10.1021/acsanm.9b01115
Abstract: Media lubricants are critical to the reliability of hard disc drives (HDDs). Ideally, the lubricant should have high thermal stability and low monolayer (ML) thickness. Unfortunately, the state-of-the-art lubricant perfluoropolyether (PFPE) only has limited thermal… read more here.

DOI: 10.1021/acsphotonics.9b00471
Abstract: Application of spectroscopic photo-detecting technologies in future innovations such as wearable or integrated electronics will require miniaturized spectrometers. This can be achieved by using an array of small-area, wavelength-selective photodetectors. Here, filterless narrowband photodetectors based… read more here.
