Summary: Experimental results show that controlled contamination is crucial for consistent surface wettability alterations after low-temperature annealing. Analysis reveals that contamination with hydrophobic PDMS may arise from the furnace, resulting in water repellency on the surface. Annealing in a contaminant-free furnace preserves initial superhydrophilicity, while annealing in a contaminated furnace leads to different wettability transitions.

Summary: The polymer emulsion with multi-fluoromethyl structure synthesized through emulsion polymerization exhibits strong dispersibility and adsorption as a wettability reversal agent. It can effectively change the wettability of core surfaces and reduce surface energy, maintaining good performance even after long term storage. Additionally, the permeability of cores with different permeability is improved to varying degrees after injection of the polymer emulsion, with higher water permeability resulting in greater improvement in core permeability. Visual displacement experiments show that the displacement efficiency can be effectively improved, with oil recovery efficiency increased by more than 13% compared to basic polymer displacement.

Summary: Superhydrophobic ZnO@stearic acid nanoarrays prepared by hydrothermal method exhibit a transition to superhydrophilic surface under UV-Visible light irradiation, attributed to the excitation of electron-hole pairs and reaction with adsorbed O-2 and H2O from air. The introduced defect energy levels of oxygen vacancies promote the excitation of more electron-hole pairs by visible light. Heating the surface further desorbs the photoinduced hydroxyl radicals, reverting the superhydrophilic surface back to superhydrophobic, with accelerated transition by increasing temperature. Additionally, the ZnO@STA nanorod array shows excellent cycle stability in reversible switch between superhydrophobicity and superhydrophilicity.

Summary: In this paper, a new type of Airy beam resulting from the modification of Fourier spectrum is introduced numerically and experimentally. The autofocusing Airy beam (AAB) exhibits off-axis autofocusing and transverse self-accelerating properties, resulting in a needle-like focus in the longitudinal direction and a tiny focal spot at the focusing plane. The focusing properties of the AAB, such as focusing position, focal spot size, focusing intensity, and depth of focus, can be adjusted by modulating its parameters. Experimental demonstrations of particle trapping and manipulation using the AAB are also presented. The number of trapped particles can be controlled by changing the focal spot size at the autofocusing plane. Our results have practical applications in particle manipulation, fluorescent imaging technology, laser spectroscopy, and other fields.

Summary: This study reports a method to design and write low-energy layer edge states (LESs) on quasi-2D hybrid perovskite single crystals using femtosecond laser ablation with high spatial resolution. The LESs are formed by laser-induced BA escaping from the lattice, resulting in the transformation of the quasi-2D structure to smaller bandgap 3D MAPbI(3) nanocrystals. Additionally, covering the crystal with tape generates an additional high-energy emission state.

Summary: To achieve carbon neutrality, it is important to design materials and structures that can simultaneously collect and convert energy. However, directly coupling energy collection and conversion modules can lead to problems such as material wearing, spatial constraints, and low conversion efficiency. This study presents a remote-controlled energy harvesting strategy that utilizes diffusive airflow within a confined channel. The device separates the energy collection unit from the conversion units, and uses two drain electrodes to collect and release electrostatically induced charges, resulting in efficient output performance.

Summary: This study presents the development of a new two-dimensional liquid crystal grating device with asymmetric surface anchoring. By using a waffle-shaped electrode on one substrate, a two-dimensional electric field is generated. The introduction of weak anchoring energy on one of the substrates allows for easier rotation of liquid crystal molecules between the electrodes upon voltage application in an asymmetrically anchored device. As a result, the proposed grating device exhibits a significant spatial phase difference in any direction, resulting in a high haze value in the opaque state.
