Summary: This work reports a stretch-tolerant superhydrophobic, self-cleaning graphene-based strain sensor with high sensitivity achieved through a prestretching strategy. The sensor exhibits outstanding self-cleaning performance and retains super-hydrophobicity even under stretching, making it insensitive to common liquids such as tea, milk, and coffee. It also achieves wide sensing ranges and superior sensitivity, showing great potential for accurate human motions monitoring in both air and underwater environments. Additionally, the sensor can be used for real-time traffic flow monitoring on bridges.

Summary: A superhydrophobic and photocatalytic composite fiber material is developed using polystyrene polydimethylsiloxane and graphitic nitride and characterized using SEM. The contact and sliding angles are measured to test hydrophobicity, and the degradation of methylene blue is used to monitor photocatalytic activity. This material creates a self-cleaning surface by repelling hydrophilic pollutants, allowing easy removal of low surface tension pollutants, and degrading fully wetted pollutants through photocatalytic oxidation.

Summary: This work presents a facile method for fabricating chemically stable superhydrophobic surfaces using biocompatible, fluorine-free, carbon-rich biochar. The biochar was synthesized from dried rice straw through pyrolysis at 550 degrees C and characterized using FTIR and SEM. The biochar-coated surface exhibited superhydrophobic behavior with a static water contact angle greater than 150 degrees. The stability of the Cassie-Baxter wetting regime allowed the aqueous drops to remain in a superhydrophobic state, showing very high water contact angle (>160 degrees) and self-cleaning behavior. No harsh chemical treatment was performed on the biochar, and a simple method of creating a biochar layer on the substrate was adopted. The surface also demonstrated repellent properties against aqueous mixtures of deep eutectic solvent (DES), allowing for easy formation of spherical DES drops for image analysis and assessment of liquid sample density.

Summary: With the development of Lab on a chip technology, fluid management using dispersed droplets has become an important approach. Electrowetting on dielectric (EWOD) is one method for droplet actuation, but it requires prior definition of droplet positions. Optoelectrowetting (OEW) goes further by allowing changes in electrical parameters through impinging light spots, without the need for predefined droplet positions. This study re-evaluates the key parameters of OEW and explores their effects on droplet actuation using numerical optimization methods.

Summary: Recent studies have shown that two-dimensional Janus transition metal dichalcogenides (TMDs) have great potential for applications in gas sensors. By conducting first principles calculations, this study explores the potential application of Pd-doped monolayer HfSeS as gas sensor materials for detecting CO, CO2, NH3, and NO. The results demonstrate the good thermodynamical stability and reversible adsorption of these molecules on both pristine and Pd-doped HfSeS, with Pd-doped HfSeS showing higher sensitivity towards NO due to its metallic behavior upon NO adsorption.
