Reliable Tissue Grasping in Robotic Minimally Invasive Surgery Enabled by Optical‐Based Slip Sensing
Advanced Engineering Materials, EarlyView.An optical‐based slip sensing method using a complementary metal–oxide–semiconductor image sensor with a built‐in infrared light emitting diode enables real‐time detection of tissue slippage—including displacement, direction, and speed—in robotic minimally invasive surgery.

Advanced Engineering Materials, EarlyView.A powerful electronic control system enables a dielectric elastomer pump to operate at resonance, matching conventional pump performance. Using self‐sensing to reconstruct load pressure dynamically, the adaptive control adjusts resonance frequency accordingly.

Long Term Follow-Up Safety and Effectiveness of Myopia Refractive Surgery
International Journal of Environmental Research and Public Health, 2020 (1) Background: Refractive surgery is an increasingly popular procedure for decreasing spectacle or contact lens dependency. The two most common surgical techniques to correct myopia are photorefractive keratectomy (PRK) and femtosecond laser-assisted in

Advanced Functional Materials, EarlyView.Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

Impact of corneal refractive surgery on the precorneal tear film
Indian Journal of Ophthalmology, 2020 Corneal refractive surgeries are one of the commonly performed procedures for correction of refractive errors. Tear film abnormality is the most common postoperative complication of corneal refractive surgeries. Consequently, these procedures represent a

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.The ultraselective H2S detection of the ZIF‐L/SnS2 heterostructure is demonstrated. The introduction of 2‐dimensional (2D) breathable ZIF‐L results in a substantial increase in H2S selectivity attributable to the molecular sieving effect, which impedes the permeation of gases with large kinetic diameters and high polarity.
