Abstract
Artificial superhydrophobic surfaces are garnering constant attention due to their wide applications. However, it is a great challenge for superhydrophobic materials to simultaneously achieve good oil repellency, mechanochemical robustness, adhesion, thermomechanical properties, and multiresponsive ability. Herein, we propose a highly efficient multifluorination strategy to prepare superhydrophobic nanocomposites with the above features, which can be used as monoliths or coatings on various substrates. In this strategy, long-chain perfluorinated epoxy (PFEP) provides outstanding water/oil repellency, tetrafluorophenyl-based epoxy (FEP) possesses good thermodynamic compatibility with PFEP and increases the mechanical performance of the matrix, and carbon nanotubes grafted with perfluorinated segments and flexible spacers (FCNTs) tailor the surface roughness as well as impart multiple functions and ensure good binding interfaces. Notedly, all of the applications of constrained long-chain perfluorinated compounds are achieved via thiol-ene click chemistry, following the ethos of atom economy. The resultant PFEP30/FCNTs40 exhibits superhydrophobicity and oleophobicity, thermal conductivity (1.33 W·m-1·K-1), electronic conductivity (232 S m-1), and electromagnetic interference shielding properties (∼30 dB at 8.2-12.4 GHz, 200 μm). Importantly, after different extreme physical/chemical tests, the PFEP30/FCNTs40 coating still shows outstanding water/oil repellency. In addition, the coating exhibits good photo/electrothermal conversion ability and shows the potential for sensor application. Moreover, the novel strategy provides an efficient guideline for large-scale preparation of robust, multiresponsive, superhydrophobic, and oleophobic materials.

Abstract
Lack of tumor targeting and low drug payload severely impedes various nanoagents further employed in small-cell lung cancer (SCLC). Therefore, how to develop a new targeting ligand and enhance drug payload has been an urgent need for SCLC therapy. Herein, we first sift and verify that capreomycin (Cm) has a high affinity toward CD56 receptors overexpressed on SCLC cells. Motivated by the concept of self-targeted drug delivery, Cm is selected as the specific targeting ligand toward CD56 receptors and chemodrug doxorubicin (Dox) is adopted to be covalently linked via the redox-responsive disulfide linkage. The synthesized self-distinguishing prodrug (Dox-ss-Cm) and FDA-approved photosensitizer indocyanine green (ICG) as structural motifs can be self-assembled into theranostic nanoagents (ICG@Dox-ss-Cm NPs) within an aqueous solution. Such carrier-free nanoagents with high drug payload can exert targeted on-demand drug release under multiple stimuli of intracellular lysosomal acidity, glutathione (GSH), and an external near-infrared (NIR) laser. Besides, our nanoagents can be specifically self-targeted to SCLC sites in vivo and self-distinguishing via SCLC cells in vitro; thus, they decrease the undesirable effects on normal tissues and organs. Further in vitro and in vivo studies uniformly confirm that such nanoagents show highly synergistic effects for SCLC chemo-photothermal therapy (PTT) under the precise guidance of NIR fluorescence (NIRF)/photoacoustic (PA) imaging. Taken together, our work can provide a novel and promising strategy for the targeted treatment of SCLC.

Abstract
Bioactive molecules play a vital role in the process of regulating the redox balance in the intracellular environment, especially in maintaining the function of organelles. To explore the association and function of bioactive molecules in organelles, it is essential to develop a chemosensor tool that uses multiresponse fluorescence signals to distinguish between and track two related bioactive molecules in organelles. However, the development of sensors with multiresponse functions is still a challenging task. Herein, we present a unique and practical single chemosensor (Mito-CTC) that can monitor HClO (as an oxidative substance) and H2S (as a reductive substance) in mitochondria (organelle targeting) with multiresponse fluorescence signals. The response of the sensor to HClO and H2S changes from red to green and blue channel emission simultaneously, respectively, thereby providing a specific signal response to reductive/oxidative substances in the mitochondria. Using a single chemosensor, we have realized multichannel bioimaging of the exogenous and endogenous HClO and H2S in cellular mitochondria. Additionally, the excellent properties of the sensor Mito-CTC can be used to reveal the relationship between HClO and H2S in mitochondria. Meanwhile, Mito-CTC has been endowed with the ability to image in bacteria and zebrafish attributed to the good permeability and low cytotoxicity. Expectantly, drug-induced liver injury (DILI) caused by fluoxetine (an antidepressant drug) and the degree of drug-induced toxicity to the liver were evaluated using Mito-CTC through discriminating and imaging HClO, indicating that Mito-CTC has the potential function of evaluating the toxicity of the drug to the liver.

Abstract
Optical characteristics of luminescent materials, including emission color (wavelength), lifetime, and excitation mode, play crucial roles in data communication and information security. Conventional luminescent materials generally display unicolor, unitemporal, and unimodal (occasionally bimodal) emission, resulting in low-level readout and decoding. The development of multicolor, multitemporal, and multimodal luminescence in a single material has long been considered to be a significant challenge. In this study, for the first time, the superior integration of colorful (red-orange-yellow-green), bitemporal (fluorescent and delayed), and four-modal (thermo-/mechano-motivated and upconverted/downshifted) emissions in a particular piezoelectric particle via optical multiplexing of dual-lanthanide dopants is demonstrated. The as-prepared versatile NaNbO3 :Pr3+ ,Er3+ luminescent microparticles shown are particularly suitable for embedding into polymer films to achieve waterproof, flexible/wearable and highly stretchable features, and synchronously to provide multidimensional codes that can be visually read-out using simple and commonly available tools (including the LED of a smartphone, pen writing, cooling-heating stimuli, and ultraviolet/near-infrared lamps). These findings offer unique insight for designing highly integrated stimuli-responsive luminophors and smart devices toward a wide variety of applications, particularly advanced anticounterfeiting technology.

Abstract
Soft actuators have attracted a lot of attention owing to their biomimetic performance. However, the development of soft actuators that are easily prepared from readily available raw materials, conveniently utilized, and cost-efficient is still a challenge. Here, we present a simple method to fabricate a polyethylene-based soft actuator. It has controllable anisotropic structure and can realize multiple motions, including bidirectional bending and twisting based on dual mechanisms, which is a rare phenomenon. Especially, the soft actuators can response at a very small temperature difference (Δ T ≥ 2.3 °C); therefore, even skin touch can quickly drive the actuator, which greatly broadens its applications in daily life. The soft actuator could demonstrate a curvature up to 7.8 cm-1 accompanied by powerful actuation. We have shown that it can lift an object 27 times its own weight. We also demonstrate the application of this actuator as intelligent mechanical devices.

Abstract
Stimulus-responsive hydrogels, which can undergo significant physicochemical changes in response to various physical or chemical stimuli, have drawn wide attention in many fields. In this study, novel photoresponsive hydrogels prepared by free radical copolymerization of xylan-type hemicellulose methacrylate with 4-[(4-acryloyloxyphenyl)azo]benzoic acid (AOPAB) were investigated, which showed multiresponsive behaviors to pH, water/ethanol alternating solutions, and light. The swelling ratios of the prepared hydrogels in distilled water decreased from 9.8 to 2.2 g/g with AOPAB content increase from 2% to 16%. The hydrogel displayed rapid swelling and deswelling performance in water and ethanol alternating solutions. Additionally, under UV irradiation the trans-conformation of azobenzene in the hydrogel would generally convert into the cis-conformation and resulted in the hydrophilic/hydrophobic balance variation of the hydrogel. Therefore, the hydrogel loaded with vitamin B12 (VB12) showed a higher drug cumulative release rate under UV irradiation than that without UV irradiation.
