Achieving multi-functions integrating reaction, separation and concentration into one-step catalysis process is a great challenge. Photocatalytic H 2 O 2 generation is the cleanest and cheapest way for its production. Herein, an all-in-one photocatalytic device for H 2 O 2 generation was designed by catalysis layer with ZIF-8/C 3 N 4 composite and carbon dots-based evaporation layer (CDE). With this device, H 2 O 2 solution with high concentration is obtained, and no need for extra separation and concentration processes. Under 2 sun illumination (3 h), H 2 O 2 evolution reaches 17.13 μmol and H 2 O 2 solution concentration gets to 10.15 mmol L −1 . Mole fraction of H 2 O 2 solution obtained by all-in-one device is 1.86 times more concentrated than that of not concentrated H 2 O 2 solution. Besides, multiples devices can work concurrently to realize large-scale production and gain large amounts of H 2 O 2 solution with high concentration. Moreover, all-in-one devices can be reused at least ten cycles. The relation between the structure and performance of the photocatalysis device is further studied by COMSOL Multiphysics software and mathematical analysis. All-in-one photocatalytic device promotes H 2 O 2 photoproduction closer to the practical application due to realizing continuous production of amounts of aqueous solution of H 2 O 2 with high concentration in one-step.

Rhenium disulfide (ReS2) with distinct physicochemical properties has shown promising potential in disease theranostics, such as drug delivery, computed tomography (CT), radiotherapy, and photothermal therapy (PTT). However, the synthesis and post-modification of ReS2 agents for different application scenarios are time- and energy-consuming, which seriously hinders the clinical translation of ReS2. Herein, we proposed three facile excipient strategies for different theranostic applications of ReS2 just through the flexible use of commercial ReS2 powder. Three excipients, including sodium alginate (ALG), xanthan gum (XG), and ultraviolet-cured resin (UCR), were used to prepare different dosage forms of commercial ReS2 powder, like hydrogel, suspension, and capsule, respectively. These dosage forms of ReS2 with distinct characteristics showed great potential for second near-infrared window PTT against tumours, gastric spectral CT imaging, and functional evaluation of the digestive tract in vivo. In addition, these ReS2 formulations exhibited good biocompatibility both in vitro and in vivo, showing a promising prospect for clinical transformation. More importantly, the facile excipient strategies for commercial agents pave a bridge to the development and wide bioapplication of many other theranostic biomaterials.

Self-healing and flexibility are significant for many emerging applications of secondary batteries, which have attracted broad attention. Herein, a self-healing flexible quasi-solid Zn-ion battery composing of flexible all-in-one cathode (VS 2 nanosheets growing on carbon cloth) and anode (electrochemically deposited Zn nanowires), and a self-healing hydrogel electrolyte, is presented. The free-standing all-in-one electrodes enable a high capacity and robust structure during flexible transformation of the battery, and the hydrogel electrolyte possesses a good self-healing performance. The presented battery remains as a high retention potential even after healing from being cut into six pieces. When bending at 60°, 90°, and 180°, the battery capacities remain 124, 125, and 114 mAh g −1 , respectively, cycling at a current density of 50 mA g −1 . Moreover, after cutting and healing twice, the battery still delivers a stable capacity, indicating a potential use of self-healing and wearable electronics.

Wide-bandgap semitransparent perovskite photovoltaics are emerging as one of the ideal candidates for building-integrated photovoltaics (BIPV). However, surface defects in inorganic CsPbBr3 perovskite prepared by vapor deposition severely limit the optoelectronic performance of perovskite solar cells. To address this issue, a strategy of doping a trace amount of KBr into perovskite by vapor deposition is adopted, effectively improving the quality of the film, reducing surface defect concentration, and enhancing the transportation and extraction of charge carriers. Simultaneously, fully physical vapor deposition technology is employed to fabricate perovskite solar cells with an average visible light transmittance of 44%. These devices exhibited an ultrahigh open-circuit voltage of 1.55 V and a superior power conversion efficiency (PCE) of 7.28%, demonstrating excellent moisture and heat resistance. Moreover, the corresponding 5 cm × 5 cm modules achieve a PCE of 5.35% with great thermal insulation capability. This work provides an approach for fabricating highly efficient all-inorganic perovskite solar cells with high average visible light transmittance, demonstrating new insights into their application in building-integrated photovoltaics.

The development of integrated high-performance supercapacitors with all-in-one configuration, excellent flexibility and autonomously intrinsic self-healability, and without the extra healable film layers, is still tremendously challenging. Compared to the sandwich-like laminated structures of supercapacitors with augmented interfacial contact resistance, the flexible healable integrated supercapacitor with all-in-one structure could theoretically improve their interfacial contact resistance and energy densities, simplify the tedious device assembly process, prolong the lifetime, and avoid the displacement and delamination of multilayered configurations under deformations. Herein, a flexible healable all-in-one configured supercapacitor with excellent flexibility and reliable self-healing ability by avoiding the extra healable film substrates and the postassembled sandwich-like laminated structures is developed. The healable all-in-one configured supercapacitor is prepared from in situ polymerization and deposition of nanocomposites electrode materials onto the two-sided faces of the self-healing hydrogel electrolyte separator. The self-healing hydrogel film is obtained from the physically crosslinked hydrogel with enormous hydrogen bonds, which can endow the healable capability through dynamic hydrogen bonding. The assembled all-in-one configured supercapacitor exhibits enhanced capacitive performance, good cycling stability, reliable self-healing capability, and excellent flexibility. It holds broad prospects for obtaining various flexible healable all-in-one configured supercapacitors for working as portable energy storage devices in wearable electronics.

β-cyclodextrin(βCD)-based star polymers have attracted much interest because of their unique structures and potential biomedical and biological applications. Herein, a well-defined folic acid (FA)-conjugated and disulfide bond-linked star polymer ((FA-Dex-SS)-βCD-(PCL)14) was synthesized via a couple reaction betweenβCD-based 14 arms poly(ε-caprolactone) (βCD-(PCL)14) and disulfide-containing α-alkyne dextran (alkyne-SS-Dex), and acted as theranostic nanoparticles for tumor-targeted MRI and chemotherapy. Theranostic nanoparticles were obtained by loading doxorubicin (DOX), and superparamagnetic iron oxide (SPIO) particles were loaded into the star polymer nanoparticles to obtain ((FA-Dex-SS)-βCD-(PCL)14@DOX-SPIO) theranostic nanoparticles. In vitro drug release studies showed that approximately 100% of the DOX was released from disulfide bond-linked theranostic nanoparticles within 24 h under a reducing environment in the presence of 10.0 mM GSH. DOX and SPIO could be delivered into HepG2 cells efficiently, owing to the folate receptor-mediated endocytosis process of the nanoparticles and glutathione (GSH), which triggered disulfide-bonds cleaving. Moreover, (FA-Dex-SS)-βCD-(PCL)14@DOX-SPIO showed strong MRI contrast enhancement properties. In conclusion, folic acid-decorated reduction-sensitive star polymeric nanoparticles are a potential theranostic nanoparticle candidate for tumor-targeted MRI and chemotherapy.Keywords:star polymer;β-cyclodextrin;tumor-targeted;disulfide bond;theranostic nanoparticles

The traditional multi-process to enhance tight oil recovery based on fracturing and huff-n-puff has obvious deficiencies, such as low recovery efficiency, rapid production decline, high cost, and complexity, etc. Therefore, a new technology, the so-called fracturing-oil expulsion integration, which does not need flowback after fracturing while making full use of the fracturing energy and gel breaking fluids, are needed to enable efficient exploitation of tight oil. A novel triple-responsive smart fluid based on “pseudo-Gemini” zwitterionic viscoelastic surfactant (VES) consisting of N -erucylamidopropyl- N , N -dimethyl-3-ammonio-2-hydroxy-1-propane-sulfonate (EHSB), N , N , N′ , N′ -tetramethyl-1,3-propanediamine (TMEDA) and sodium p -toluenesulfonate (NaPts), is developed. Then, the rheology of smart fluid is systematically studied at varying conditions (CO 2 , temperature and pressure). Moreover, the mechanism of triple-response is discussed in detail. Finally, a series of fracturing and spontaneous imbibition performances are systematically investigated. The smart fluid shows excellent CO 2 -, thermal-, and pressure-triple responsive behavior. It can meet the technical requirement of tight oil fracturing construction at 140 °C in the presence of 3.5 MPa CO 2 . The gel breaking fluid shows excellent spontaneous imbibition oil expulsion (∼40%), salt resistance (1.2 × 10 4 mg/L Na + ), temperature resistance (140 °C) and aging stability (30 days).

With notable advantages of cost-effectiveness and inherent safety, aqueous zinc-ion batteries (AZIBs) offer significant potential for large-scale energy storage. Nevertheless, the electrodes produced using traditional binders via slurry coating methods face problems of inadequate mass loadings and vulnerability to exfoliation when subjected to deformations. In this study, all-in-one integrated electrodes consisting of polyaniline active material, carbon nanotube conductive network, and carboxymethyl cellulose mechanical framework are fabricated via a scalable and cost-effective approach. Through the synergistic interaction of these constituents, the optimized integrated electrode realizes exceptional flexibility, impressive mechanical strength (20.0 MPa), excellent electrical conductivity (628.5 S m −1 ), and favorable hydrophilicity. At a mass loading of 2 mg cm −2 , the integrated electrode offers considerably improved rate capability and cyclability compared to those electrodes based on binders. Under remarkable mass loadings of 8 and 14 mg cm −2 , the integrated electrodes can deliver large areal capacities of 1.25 and 1.58 mAh cm −2 at 0.2 A g −1 and remarkable capacity retentions of 99.1 and 94.8 % after 3000 cycles, respectively. Furthermore, a high-performance pouch-type battery is assembled using the integrated electrode and demonstrates strong resistance to mechanical deformations. The proposed strategy in this work provides a new opinion for designing high-mass-loading electrodes for AZIBs.

Multifunctionality of all-in-one energy storage devices with the properties involving flexibility, interface stability, and wearability are urgently needed for portable electronic equipment. Here, we report a facile method based on interfacial cross-linking for preparing all-in-one energy storage devices, where the same polymer substrate is used in both electrode and electrolyte, while the electrolyte as the cross-linking agent to obtain more stable interface between the components of the all-in-one energy storage devices. This novel strategy endows the storage device small intrinsic impedance effect (R S =1.82 Ω) and mechanical stability; and more importantly it enables the supercapacitors to be used as public module to achieve arbitrary, designable, and multi-dimensional integration for the adaptation with complex power supply systems. The strategy is also successfully extended to aqueous Zn-MnO 2 battery. Overall, the strategy provides a universal and simple path for the integrated design of the all-in-one energy storage device as a flexible and switchable power source.

Bottlebrush copolymers with different chemical structures and compositions as well as diverse architectures represent an important kind of material for various applications, such as biomedical devices. To our knowledge, zwitterionic conjugated bottlebrush copolymers integrating fluorescence imaging and tumor microenvironment-specific responsiveness for efficient intracellular drug release have been rarely reported, likely because of the lack of an efficient synthetic approach. For this purpose, in this study, we reported the successful preparation of well-defined theranostic zwitterionic bottlebrush copolymers with unique brush-on-brush architecture. Specifically, the bottlebrush copolymers were composed of a fluorescent backbone of polyfluorene derivate (PFONPN) possessing the fluorescence resonance energy transfer with doxorubicin (DOX), primary brushes of poly(2-hydroxyethyl methacrylate) (PHEMA), and secondary graft brushes of an enzyme-degradable polytyrosine (PTyr) block as well as a zwitterionic poly(oligo (ethylene glycol) monomethyl ether methacrylate-co-sulfobetaine methacrylate) (P(OEGMA-co-SBMA)) chain with super hydrophilicity and highly antifouling ability via elegant integration of Suzuki coupling, NCA ROP and ATRP techniques. Notably, the resulting bottlebrush copolymer, PFONPN9-g-(PHEMA15-g-(PTyr16-b-P(OEGMA6-co-SBMA6)2)) (P2) with a lower MW ratio of the hydrophobic side chains of PTyr and hydrophilic side chains of P(OEGMA-co-SBMA) could self-assemble into stabilized unimolecular micelles in an aqueous phase. The resulting unimolecular micelles showed a fluorescence quantum yield of 3.9% that is mainly affected by the pendant phenol groups of PTyr side chains and a drug-loading content (DLC) of approximately 15.4% and entrapment efficiency (EE) of 90.6% for DOX, higher than the other micelle analogs, because of the efficient supramolecular interactions of π–π stacking between the PTyr blocks and drug molecules, as well as the moderate hydrophilic chain length. The fluorescence of the PFONPN backbone enables fluorescence resonance energy transfer (FRET) with DOX and visualization of intracellular trafficking of the theranostic micelles. Most importantly, the drug-loaded micelles showed accelerated drug release in the presence of proteinase K because of the enzyme-triggered degradation of PTyr blocks and subsequent deshielding of P(OEGMA-co-SBMA) corona for micelle destruction. Taken together, we developed an efficient approach for the synthesis of enzyme-responsive theranostic zwitterionic conjugated bottlebrush copolymers with a brush-on-brush architecture, and the resulting theranostic micelles with high DLC and tumor microenvironment-specific responsiveness represent a novel nanoplatform for simultaneous cell image and drug delivery.Keywords:brush-on-brush;zwitterionic;enzyme-responsive;theranostic;FRET

Theranostics is an emerging technique for cancer treatments due to its safety and high efficiency. However, the stability, efficiency, and convenience of preparation are the main challenges for developing theranostics. Here we describe a one-pot process for biocompatible metal–organic framework (MOF)-based theranostics. The ligand H2L designed for the MOF enables both red fluorescence emission and photodynamic therapy (PDT). The frame and regular channel structure of H2L-MOF empower the theranostics with good drug delivery performance, and the uniform and nano-sized particles facilitate the in vivo imaging/therapy applications. In vivo fluorescence imaging and in vitro chemo-photodynamic therapy were achieved with the MOF without any further modification. Our results reveal an effective strategy to achieve multifunctional theranostics by the synergistic action of the organic ligand, metal node, and channel structure of MOF nanoparticles.Keywords:metal–organic framework (MOF);multifunction;fluorescence;chemotherapy;photodynamic therapy

Indocyanine green (ICG) has been widely explored for the theranostics of tumors. However, ICG mainly accumulates in the liver, spleen, or kidney in addition to in tumors, causing inaccurate diagnoses and impaired therapeutic effects under NIR irradiation. Herein, a hybrid nanomicelle was constructed by integrating hypoxia-sensitive iridium(III) and ICG for precise tumor localization and photothermal therapy in sequence. In this nanomicelle, the amphiphilic iridium(III) complex (BTPH)2Ir(SA-PEG) was synthesized through the coordination substitution of hydrophobic (BTPH)2IrCl2 and hydrophilic PEGlyated succinylacetone (SA-PEG). Meanwhile, PEGlyated ICG (ICG-PEG) as a derivative of the photosensitizer ICG was also synthesized. (BTPH)2Ir(SA-PEG) and ICG-PEG were coassembled by dialysis to form the hybrid nanomicelle M-Ir-ICG. Hypoxia-sensitive fluorescence, ROS generation, and the photothermal effect of M-Ir-ICG were investigated in vitro and in vivo. The experimental results indicated that M-Ir-ICG nanomicelles could locate at the tumor site first and then perform photothermal therapy with 83.90% TIR, demonstrating great potential for clinical applications.
