Most of the existing single-component nanostructures cannot provide comprehensive diagnostic information, and their treatment strategies always have to combine other therapeutics as a complementary for effective biomedical application. Here, we adopted a facile approach to design a theranostic nanoflower (NF) with robust efficacy for comprehensive tumor diagnosis and quadruple synergistic cancer therapy. The NF is equipped with a metallic hybrid of several functional elements and flower-like superstructures and thus shows excellent in vitro and in vivo theranostic performance. It shows high X-ray attenuation coefficiency for the Bi element, strong near-infrared (NIR) plasmon absorbance and singlet oxygen (1O2) generation ability for the Mo element, and great photothermal conversion efficiency (54.7%) because of enhanced photoabsorption of the petal structure. Moreover, the NF realizes a very high doxorubicin-loading efficiency (90.0%) and bimodal pH/NIR-responsive drug release, posing a promise as a controlled drug carrier. The NF also shows excellent performance at trimodal magnetic resonance/X-ray computed tomography/photoacoustic imaging for comprehensive tumor diagnosis. To our best knowledge, it is the first time that integrating at least seven functions into one biomedical nanomaterial for well-rounded tumor theranostics has been reported. This “all-in-one” NF opens a new perspective in developing novel and efficient multifunctional nanotheranostics.

The high theoretical capacity of Sb-based intermetallic alloys makes them attractive potential anode materials for sodium-ion batteries (SIBs) with high energy density . However, their cycling stability is greatly restricted by the huge volumetric variations resulted from the intrinsic (de-)alloying mechanism. Herein, we demonstrate a unique lattice softening mechanism, which enables highly reversible sodium storage and stable cycling of the as-prepared Bi–Sb alloy/carbon nanofibers electrodes. Theoretical analyses show that the elastic modulus of Bi–Sb alloys is reduced whereas the toughness is enhanced by tuning the lattice chemistry of rhombohedral Bi–Sb alloys, which is of great importance in relieving the concentrated stress during the continuous (de-)sodiation processes. In-situ characterization and electrochemical evaluations demonstrate that the electrodes made of BiSb 3 /C nanofibers exhibit high anti-pulverization capability upon Na-cycling and extraordinary long-life cyclability. Specifically, a highly reversible capacity of 233.2 mAh g −1 at 2 A g −1 is achieved over 2500 cycles. Moreover, a full cell assembled with the pre-sodiated BiSb 3 /C anode and a Na 3 V 2 (PO 4 ) 3 /C cathode delivers a high reversible capacity of 333.2 mAh g −1 at 0.2 A g −1 over 200 cycles. This present work provides further understandings and new solution for developing high-performance alloying-based anodes for SIBs.

The integration of photothermal therapy (PTT), photodynamic therapy (PDT), and immunotherapy represents a promising strategy for enhancing anticancer efficacy. However, current approaches often rely on cocktail-based nanoplatforms that load multiple agents, which complicates preparation and raises concerns about stability and potential side effects. Therefore, developing structurally simple, easily synthesized nanomaterials with inherent multifunctionality is highly desirable. In this work, we report the first synthesis of biocompatible heterostructures. The interfacial contact within these heterostructures facilitates efficient charge carrier separation, enabling the simultaneous activation of photothermal conversion and photodynamic functionalities under near-infrared (NIR) irradiation. Beyond these photophysical effects, the obtained Bi₂Se₃@BiSe nanosheets effectively polarize M0 macrophages toward the tumor-suppressive M1 phenotype, a process which in turn promotes robust immunogenic cell death. Collectively, this work establishes Bi₂Se₃@BiSe as a versatile nanoplatform for triple-modal cancer therapy, seamlessly integrating PTT, PDT, and immunotherapy, thus proposing a novel paradigm for developing next-generation combinatory cancer therapeutics.

Restructuring is an important phenomenon in catalytic reactions. Conversion-type materials with suitable redox potential may undergo in situ electrochemically driven restructurings and induce highly active catalytic sites in a working lithium–sulfur battery. Herein, driven by the electrochemical conversion reaction of BiVO4, a reversible catalytic cycle of Bi/amorphous Li3VO4 (a-Li3VO4) and Bi2S3/a-Li3VO4 heterojunctions is constructed, which targets the oxidation of Li2S and the conversion of polysulfide, respectively. The heterostructures and electrochemically driven size confinement provide abundant sites for shuttle restraining and sulfur conversion. Especially, the p-block Bi and Bi2S3 could dramatically reduce the conversion energy barriers of Li2S and polysulfide by virtue of the p–p orbital hybridization, promoting bidirectional reactions of the sulfur cathode. As a result, the corresponding sulfur cathode possesses a high reversible capacity of 7.5 mAh cm–2 after 120 cycles under a high sulfur loading of 10.3 mg cm–2 with a current density of 0.38 mA cm–2. This study furnishes a feasible scheme to obtain highly effective catalysts for bidirectional sulfur redox by utilizing the electrochemically induced restructuring.

As one of the important electronic components, the dielectric capacitors for energy storage applications have been extensively studied in recent years. Among various dielectric materials, the perovskite oxide Bi 0.5 Na 0.5 TiO 3 -based ceramics have become promising candidates due to their high polarization, dielectric tunability, environment-friendly composition, and so forth. Herein, the relaxor ferroelectric ceramics of Bi 0.5 Na 0.5 TiO 3 –SrTiO 3 –Bi(Mg 0.5 Zr 0.5 )O 3 were prepared via solid-state reaction method. The sample with optimal composition not only retains the high polarization by introducing Bi 3+ ions, but also achieves the reduced remanent polarization by enhancing relaxor behavior and the promoted electric breakdown strength by the grain size refinement. Accordingly, a high recoverable energy density of 8.3 J/cm 3 under 450 kV/cm and the superb charge/discharge properties (current density C D = 1200 A/cm 2 , power density P D = 150 MW/cm 3 , charge/discharge time t 0.9 = 0.15 µs) are achieved, revealing great prospect in energy storage applications.

A phosphazene-triazine bi-base sulfonate compound (CPNS) was synthesized using hexachlorocyclotriphosphazene, cyanuric chloride, and sodium p-hydroxybenzene sulfonate as raw materials. The chemical structure was determined by FTIR, 1 H NMR 31 P NMR (NMR stands for nuclear magnetic resonance), and elemental analysis of P, Na. To study the flame retardant properties of CPNS, a series of modified polycarbonate (MPC) with different ratios of CPNS were prepared. The flame retardant performance and thermal stability of CPNS/MPC were characterized by limiting oxygen index (LOI), UL-94 vertical burning test, cone calorimetry test, and TG. Results show that when CPNS is added to 0.3%, the CPNS/MPC can pass the UL94 V-0 level with an LOI value of 35.3% and reduce the peak heat release rate by 16.89% during the combustion. TG results show that adding 0.1% CPNS can decrease the initial decomposition temperature of the MPC by 68°C in nitrogen and 27°C in air. The reduction of the initial decomposition temperature means that the flame retardant promotes the isomerization reaction of polycarbonate accelerates the formation of an intermediate char on the surface. Investigation of intermediate char residue's morphology and chemical structure demonstrates that CPNS promotes the formation of more complete and compact char residue, which acts not only there is increased opportunity for radical recombination reactions in the condensed phase but also as physical barriers to inhibit the transfer of heat and oxygen, resulting in good flame retardant properties.

Single-crystal p-type ZnSe nanowires (NWs) with zinc blende structure and [21–1] growth direction were synthesized by using bismuth (Bi) as dopant via a thermal co-evaporation method. The ZnSe : Bi NWs showed evident p-type conductivity with hole concentration up to 4.1 × 1018 cm−3 after the acceptor activation. Negative photoconductivity was first investigated in the p-ZnSe NWs, i.e., the conductivity of the NWs under light was dramatically lower than that in the dark. Surface effects arising from oxygen absorption and photo-desorption were suggested to be responsible for this. By using Al as the Schottky gate, high-performance nano-metal-semiconductor field-effect transistors (nanoMESFETs) were constructed, and measurements on the Al/p-ZnSe NW Schottky diode also revealed the bias-dependent photoresponse. It is expected that the p-type ZnSe : Bi NWs will have great potential in nano-optoelectronic applications.

A recent hot-spot topic for flexible and wearable devices involves high-performance nonvolatile ferroelectric memories operating under compressive or tensile mechanical deformations. This work presents the direct fabrication of a flexible (Mn,Ti)-codoped multiferroic BiFeO3 film capacitor with Pt bottom and Au top electrodes on mica substrate. The fabricated polycrystalline Bi(Fe0.93Mn0.05Ti0.02)O3 film on mica exhibits superior ferroelectric switching behavior with robust saturated polarization (Ps ∼ 93 μC/cm2) and remanent polarization (Pr ∼ 66 μC/cm2) and excellent frequency stability (1–50 kHz) and temperature resistance (25–200 °C), as well as reliable long-lifetime operation. More saliently, it can be safely bent to a small radius of curvature, as low as 2 mm, or go through repeated compressive/tensile mechanical flexing for 103 bending times at 4 mm radius without any obvious deterioration in polarization, retention time at 105 s, or fatigue resistance after 109 switching cycles. These findings demonstrate a novel route to designing flexible BiFeO3-based ferroelectric memories for information storage and data processing, with promising applications in next-generation smart electronics.

As a topological insulator material, bismuth selenide (Bi₂Se₃) exhibits unique physical properties and a narrow bandgap, offering significant potential for applications in next-generation optoelectronic devices. Nevertheless, its narrow bandgap characteristic causes transient carriers generated by photoexcitation to relax rapidly, hindering the realisation of ideal photodetection performance and impeding practical applications. This study addresses this challenge by combining a simple, cost-effective synthesis method with bandgap engineering. By constructing an internal electric field at the heterojunction interface, we effectively suppress carrier recombination, facilitating rapid charge separation and collection. The resulting self-powered photodetector achieves a responsivity of 48.3 mA/W, a specific detectivity of 9.42 × 10 11 Jones, and a millisecond-range response time under 808 nm illumination. Furthermore, the device possesses broadband detection capability spanning the visible to infrared spectrum. Moreover, the device functions as a signal receiver for precise near-infrared optical communication at zero bias, demonstrating potential for application in the field of optical communications. In view of the simple, scalable and silicon-compatible fabrication method, the fabrication of Bi₂Se₃/Si photodetectors holds significant application potential in the fields of rapid broadband detection and optical communications, and also offers novel insights for the construction of other silicon-based detectors.

The enhancement of the energy storage property of capacitor films at elevated temperature has been considered a critical area of research owing to the essential requirements of capacitor applications. In the present study, a ternary composite system with an improved energy storage property is reported. The ternary composite was composed of PP-graft-AA chains (acrylic acid grafting) and a PP/nano-ZrO2 matrix and was biaxially oriented into a defect-free film with a thickness of 10 μm. The obtained film (BO(PP/AA/Zr)) exhibited an energy storage density of 7.9 J cm−3 at room temperature and maintained a considerably high value of 3.9 J cm−3 at 120 °C. The characterization of charge carrier transportation indicated that the effective biaxial orientation and the introduction of the polar grafted functional group and nanofillers increased the activation energy of molecular chain segment motion and deepened electron trap energy levels, which limited the transportation of charge carriers and significantly enhanced the breakdown strength and energy storage property. Moreover, the designed graft-modified chains (acrylic acid grafted) modified the compatibility between the polymer and inorganic nanofiller, thereby improving the processibility of the defect-free thin film. The results of dynamic mechanical analysis and 2D micro-infrared spectra indicated that the graft-modified chains offset the increased elastic rigidity caused by nanoparticles and facilitated the interaction between inorganic nano-ZrO2 and polymer chains. The study provides a potential solution to the challenge that nanocomposites face during the commercial production of defect-free biaxially oriented films.

Electrolysis of (bi)carbonates into valuable chemicals using renewable electricity is an attractive strategy to integrate CO 2 capture and valorization systems for reducing carbon emissions. Optimizing the proton concentration on the catalyst surface in (bi)carbonate electrolyzers can enable rapid local CO 2 release, making it a promising approach for enhancing electrocatalytic performance. This paper describes an efficient surface modification strategy using organic molecules with low p K a values to facilitate the accumulation of protons near the electrode. Operando Raman results prove that the modifier could promote pH swinging and increase the local CO 2 concentration. Consequently, when operated at a current density of 100 mA cm −2 , the acid-modified catalyst exhibited a CO Faradaic efficiency of 60%, higher than that of the base-modified catalyst, producing syngas with a CO/H 2 ratio of 0.5 at the cell voltage of 3.3 V. The proposed method offers promising new solutions for the development of commercially relevant integrated CO 2 reduction systems.

We have prepared novel (1- x )[(1- y )NaNbO 3 -yBi(Mg 2/3 Nb 1/3 O 3 )]- x NaMgF 3 (NN-BMN-NMF) ternary oxyfluoride solid solutions and investigated their structural, dielectric, electrical, and energy storage properties in this work. The single BMN-doped solid solution experiences a transformation from the Pbma to the P2 1 ma phase. The NMF and BMN codoping further induce the pseudo-cubic phase Pmmm, exhibiting the coexistence of the P2 1 ma and Pmmm phases. The MgO secondary phase appeared in the high-level doped compositions. The single BMN or NMF-doped composition demonstrates a homogeneous microstructure. However, the codoped ones exhibit a core-shell fine-grain microstructure. The NMF and or BMF doping decreases the polarizability of the solid solution. The single BMN-doping or NMF and BMN-codoping shifts the Tc toward much lower temperatures, accompanied by a broader permittivity maximum, than the same level of single NMF-doping. The NMF ( x = 0.02) and BMN ( y = 0.10) codoped composition achieved optimized energy storage properties with recoverable energy density W rec = 3.76 J/cm 3 , efficiency η = 80.7%, and breakdown strength ( E b ) = 380 kV/cm.
