Optothermal evaluation of oil film thickness on water
Journal of Applied Physics, 1992 A thermally stimulated spectroscopic approach is described for remote thickness evaluation of a crude oil film on water, with possible applications to airborne monitoring of oil spills. The oil-water medium is irradiated by a laser pulse which is partially absorbed within the oil film.

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching
Advanced Functional Materials, EarlyView.A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

INFLUENCE OF LOAD AND SPEED CHANGE ON LUBRICATION PERFORMANCE OF LOW SPEED HEAVY DUTY BEARINGS
Jixie qiangdu, 2019 In order to study the lubricating property of low-speed heavy-duty bearing under the condition of different loads and speed, such as the oil film thickness, oil film pressure and changes of oil film velocity. Building model of fluid-structure interaction

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells
Advanced Functional Materials, EarlyView.Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.
