The sustainable production of chemically recyclable polymers presents a significant opportunity to polymer scientists tackle the growing environmental and energy problems current petroleum-based plastics. Despite recent advances, however, there are still pressing needs for an expanded horizon polymers. Herein, we introduce new paradigm biosourced polythioesters (PTEs) with high polymerizability complete recyclability under mild economical conditions. thiolactone monomers ring strain can be...

The metal-insulator transition is one of the remarkable electrical properties atomically thin molybdenum disulphide. Although theory electron–electron interactions has been used in modelling disulphide, underlying mechanism and detailed process still remain largely unexplored. Here we demonstrate that vertical metal-insulator-semiconductor heterostructures built from disulphide are ideal capacitor structures for probing electron states. configuration offers added advantage eliminating...
Holography, with the capability of recording and reconstructing wavefronts light, has emerged as an ideal approach for future deep-immersive naked-eye display. However, shortcomings (e.g., small field view, twin imaging, multiple orders diffraction) traditional dynamic holographic devices bring many challenges to their practical applications. Metasurfaces, planar artificial materials composed subwavelength unit cells, have shown great potential in light manipulation, which is useful...
Abstract Metasurfaces have provided a promising approach to enhance the nonlinearity at subwavelength scale, but usually suffer from narrow bandwidth as imposed by sharp resonant features. Here, we counterintuitively report broadband, enhanced second-harmonic generation, in nanopatterned hyperbolic metamaterials. The nanopatterning allows direct access of mode with large momentum, rendering rainbow light trapping, i.e. slow broad frequency, and thus enhancing local field intensity for...
Multispectral and polarized focusing imaging are key functions that vitally important for a broad range of optical applications. Conventional techniques generally require multiple shots to unveil desired information implemented via bulky multi-pass systems or mechanically moving parts difficult integrate into compact integrated systems. Here, design ultra-compact transversely dispersive metalens capable both spectrum polarization ellipticity recognition reconstruction in just single shot is...
Abstract Intelligent micromachines that respond to external light stimuli have a broad range of potential applications, such as microbots, biomedicine, and adaptive optics. However, artificial light‐driven intelligent with low actuation threshold, rapid responsiveness, designable precise 3D transformation capability remain unachievable date. Here, single‐material one‐step 4D printing strategy are proposed enable the nanomanufacturing agile low‐threshold programmable shape‐morphing...
Abstract Bilirubin, an abundant bile pigment in mammalian serum, was once considered a toxic waste product and has more recently been recognized as potent antioxidant of physiological importance. However, its potential biological functions other fields are not well understood. Herein we show that bilirubin is also powerful immunomodulatory agent. Bilirubin significantly inhibited Ag-specific polyclonal T cell responses, while similar antioxidants completely lacked this effect. suppressed...
Modern three-dimensional nanofabrication requires both additive and subtractive processes. However, processes are largely isolated generally regarded as incompatible with each other. In this study, we developed simultaneous fabrication using two-photon polymerization followed by femtosecond (fs) laser multiphoton ablation. To demonstrate the new capability, submicrometer polymer fibers containing periodic holes of 500-nm diameter microfluidic channels 1-µm were successfully fabricated. This...
Carbon soot (CS) has the advantages of cost-effectiveness and production scalability over other carbons (i.e., graphene, CNTs) in their synthesis. However, little research been conducted to explore potential applications CS. In this study, we demonstrated that a common daily waste—CS—can be used for developing cost-effective absorbent (CS-sponge) remove oil contaminants from water. The CS was synthesized by an ethylene-oxygen combustion flame. CS-sponge prepared via dip-coating method....

Rapid single-step fabrication of graphene patterns was developed using laser-induced chemical vapor deposition (LCVD). A laser beam irradiates a thin nickel foil in CH4 and H2 environment to induce local temperature rise, thereby allowing the direct writing precisely controlled positions at room temperature. Line can be achieved with single scan without pre- or postprocesses. Surprisingly, growth rate is several thousand times faster than that general CVD methods. The discovery development...

Aggregation-induced emission luminogens (AIEgens) exhibit efficient cytotoxic reactive oxygen species (ROS) generation capability and unique light-up features in the aggregated state, which have been well explored image-guided photodynamic therapy (PDT). However, limited penetration depth of light tissue severely hinders AIEgens as a candidate for primary or adjunctive clinical applications. Coincidentally, microwaves (MWs) show distinct advantage deeper tissues than light. Herein, first...
