The second near-infrared (NIR-II, 1000–1700 nm) window is advantageous for bioimaging due to its deep tissue penetration and low autofluorescence. Despite these benefits, creating highly sensitive surface-enhanced Raman scattering (SERS) nanoprobes in this range is challenging. This study introduces an ultra-sensitive SERS nanoprobe developed using plasmonic engineering. We selected the commercial Raman dye IR1061, with an absorption peak at 1061 nm, and synthesized gold nanotriangles (AuNTs) to absorb visible light and transfer energy to NIR-II phonons. The combination of IR1061 and AuNTs significantly improved the nanoprobe's sensitivity to 116 fM in the NIR-II window, due to enhanced electromagnetic fields and SERS effects. Theoretical analysis shows AuNTs have stronger electromagnetic hotspots than gold nanorods, enhancing SERS sensitivity. The nanoprobe penetrates pig tissue over 4 mm and agarose gels up to 5 cm. This work presents a novel approach to ultra-sensitive NIR-II SERS nanoprobes for bioimaging and diagnostics. It can not only overcome the bottleneck of traditional imaging technology, but also provide strong support for high-resolution imaging of deep tissues and provide more accurate information for clinical diagnosis and treatment.

Anion-intercalation lithium metal batteries (AILMBs) are appealing due to their low cost and fast intercalation/de-intercalation kinetics of graphite cathodes. However, the safety and cycliability of existing AILMBs are constrained by the scarcity of compatible electrolytes. Herein, we showcase that a difluoroester can be applied as electrolyte solvent to realize high-performance AILMBs, which not only endows high oxidation resistance, but also efficiently tunes the solvation shell to enable highly reversible and kinetically fast cathode reaction beyond the trifluoro counterpart. The difluoroester-based electrolyte demonstrates nonflammability, high ionic conductivity, and electrochemical stability, along with excellent electrode compatibility. The Li| |graphite AILMBs reach a high durability of 10000 cycles with only a 0.00128% capacity loss per cycle under fast-cycling of 1 A g −1 , and retain ~63% of room-temperature capacity when discharging at −65 °C, meanwhile supply stable power output under deformation and overcharge conditions. The electrolyte design paves a promising path toward fast-rate, low-temperature, durable, and safe AILMBs.

The high energy consumption of Carbon Capture Utilization and Storage(CCUS) promotes the research of integrated absorption and mineralization technology. A novel DEEA/AEP biphasic absorbent is used to absorb \(\hbox {CO}_{2}\) . After phase separation, only one phase enriched with the absorption product is sent into the mineralization system, then reacts with \(\hbox {Ca(OH)}_{2}\) to produce \(\hbox {CaCO}_{3}\) at normal temperature and pressure. The effects of temperature, Ca/C and dispersion of the system were investigated, and cyclic utilization experiment was also conducted. The process was characterized and analyzed by Thermal gravimetric analysis (TGA), X-ray diffraction (XRD), and nuclear magnetic resonance ( 13 C NMR). The results showed that at 50 \(^{\circ }\) C, Ca/C = 1, the extent of mineralization of \(\hbox {CO}_{2}\) -enriched phase mineralization was 95.73% after ultrasonic treatment for 30 min. During 6 cycles, the volume percentage of \(\hbox {CO}_{2}\) -enriched phase could be maintained at 52–55%, and the \(\hbox {CO}_{2}\) load was 11.92mol/L. The results above indicate that the \(\hbox {CO}_{2}\) -enriched phase mineralization technology after absorption by biphasic absorbent can effectively capture \(\hbox {CO}_{2}\) , realize recycling, and reduce CCUS energy consumption.

This study aimed to synthesize a novel nanofiber adsorbent based on metal–organic frameworks (MOFs), ZIF-94-PAN, by incorporating ZIF-94 into polyacrylonitrile (PAN) through electrospinning. The investigation of the adsorption characteristics of ZIF-94-PAN for cobalt ions was undertaken, yielding findings that suggest an optimum ZIF-94 loading content within the ZIF-94-PAN composite of 8%. The adsorption experiments revealed that, under pH 8.3 and 298 K, ZIF-94-PAN-8% attained cobalt ion equilibrium adsorption (139.08 mg/g). Additionally, the adsorption kinetics of cobalt ions exhibited conformity with the pseudo-second-order model, whereas adherence to the Freundlich isotherm model indicated a non-homogeneous, endothermic process. XPS analysis unveiled that the adsorption mechanism was characterized by the coordination of nitrogen and oxygen atoms within ZIF-94-PAN with cobalt ions. This study effectively addressed the challenges of separating and recovering MOFs adsorbents by fabricating them as nanofibers. The remarkable adsorption performance and stability of the ZIF-94-PAN nanofibers highlight their potential for removing cobalt-contaminated wastewater.

The demand for near-infrared (700–1,700 nm) materials in optical communications, laser sources and biological imaging applications has led to extensive research on lanthanide-doped nanoparticles, owing to their nanostructure modulation and interface property tunability. However, the low molar extinction coefficient of conventional lanthanide sensitizers limits the brightness of lanthanide near-infrared nanoparticles for applications in low-power excitation scenarios. Here we introduce Na 3 CrF 6 , a new crystalline nanoparticle that serves as both sensitizer and host for high-brightness near-infrared emission from lanthanide activators (Er 3+ , Tm 3+ , Yb 3+ or Nd 3+ ). We demonstrate an increase in brightness of up to 370 times compared with the most intense conventional lanthanide-sensitized nanoparticles. This discovery is also validated for other lanthanide-doped nanoparticles sensitized with low-cost transition metals (Mn 2+ or Ni 2+ ). Our transition metal-based nanoparticles represent a powerful toolbox to enable high signal-to-noise-ratio labelling and imaging with low-power excitation sources such as white light-emitting diode or persistent luminescence materials. This work paves the way for next-generation high-brightness near-infrared luminescence systems, suited for a wide range of low-illumination excitation applications.

As next-generation display technologies, eco-friendly colloidal quantum dot light-emitting diodes have drawn great attention due to their excellent luminescence properties, along with their rapid development. However, practical applications of eco-friendly quantum dot light-emitting device remain challenging, primarily due to the inferior performance of green device, which still lag behind their red and blue counterparts. Herein, we present efficient green device based on interfacial potential-graded ZnSeTe quantum dots. Our findings show that this potential-graded structure alleviates interfacial lattice mismatch and strain, reducing structural deformation and misfit defects. The smoothed interfacial potential suppresses the nonradiative recombination processes, particularly Auger recombination revealed by excitation-intensity dependent ultrafast transient absorption kinetics. Consequently, the interfacial potential-graded quantum dots demonstrate highly efficient green quantum dot light-emitting diodes, with a peak external quantum efficiency of 21.7% at 520 nm and a corresponding current efficiency of 75.7 cd A −1 .

Stretchable electronic circuits can seamlessly conform to irregular and dynamic surfaces with high integration. However, current stretchable configurations typically have limited stretchability due to the lack of robust connections between soft interconnects and rigid electronics. Here, we printed highly stretchable metal–polymer conductors on thermoplastic elastomers as interconnects. We developed electronic vests with porous surfaces for rigid electronics and introduced polyester hot-melt adhesives to strengthen connections between soft interconnects and rigid electronics. After thermal bonding, the adhesive penetrates the porous surface of electronic vests, creating a mechanical interlock and providing an adhesion force of 8.34 N/cm for the connection (3× higher than conductive adhesives). Thus, rigid electronics of different sizes and different pin counts can form strong connections to soft interconnects, achieving a maximum strain tolerance of ~700% (10× higher than conductive adhesives). We achieved highly integrated ultra-stretchable displays that can withstand stretching up to 220% without dead pixels.

With the accelerated development of modern detection and communication technology, the multifunctional wearable materials with excellent electromagnetic interference (EMI) shielding, infrared stealth, and human monitoring for improving military combat capability have received extensive attention. In this work, the lightweight melamine foam (MF)@silver nanowires (AgNWs)-iron nanowires (FeNWs) (AgFe-MF) was fabricated by a vacuum-assisted dip-coating method. Due to the porous structure and synergistic electrical and magnetic losses, this lightweight (0.115 g/cm 3 ) composite foam with an ultra-low filler content (0.62 vol.%) exhibited an ideal EMI shielding efficiency of 38.4 dB. On the other hand, the AgFe-MF realized a powerful multifunctional integration. The surface saturation temperature of the AgFe-MF reached 94.2 °C under a low applied voltage of 1.8 V and remained extremely fast heating and cooling response and terrific working stability, resulting in excellent infrared stealth and camouflage effects. Furthermore, taking virtues of the elastic porous conductive architecture, the AgFe-MF was utilized as a piezoresistive sensor exhibiting board compressive interval of 0–1.62 kPa (50% strain) with a good sensitivity of 0.57 kPa −1 . This work will provide new ideas and insights for developing multifunctional wearable devices in the fields of EMI shielding, thermal management, and piezoresistive sensing.

Bismuth-based lead-free perovskite is one of the most popular research fields in halide perovskites. However, due to the valence of Bi 3+ , Bi-based perovskite has non-cubic crystal structure, causing the film quality poor and hindering further applications. In this work, taking advantage of long-chain organic cation, i.e., phenylethylamine cation, (PEA + ), we have fabricated high-quality bismuth halide perovskite (PEA) 3 Bi 2 I 9 film, assisted by vacuum treatment, and investigated the characteristic differences between Cs 3 Bi 2 I 9 and (PEA) 3 Bi 2 I 9 . First-principle calculation has been employed next, which distinguishes the discrepancies theoretically and confirms the experimental results. Furthermore, resistive switching memory devices based on high-quality (PEA) 3 Bi 2 I 9 film have been fabricated, and clear resistive switching behaviors are observed, showing ON/OFF ratio about 100 and retention time above 10 3 s.

Leukemia is a kind of hematological malignancy originating from bone marrow, which provides essential signals for initiation, progression, and recurrence of leukemia. However, how to specifically deliver drugs to the bone marrow remains elusive. Here, we develop biomimetic vesicles by infusing hematopoietic stem and progenitor cell (HSPC) membrane with liposomes (HSPC liposomes), which migrate to the bone marrow of leukemic mice via hyaluronic acid-CD44 axis. Moreover, the biomimetic vesicles exhibit superior binding affinity to leukemia cells through intercellular cell adhesion molecule-1 (ICAM-1)/integrin β2 (ITGB2) interaction. Further experiments validate that the vesicles carrying chemotherapy drug cytarabine (Ara-C@HSPC-Lipo) markedly inhibit proliferation, induce apoptosis and differentiation of leukemia cells, and decrease number of leukemia stem cells. Mechanically, RNA-seq reveals that Ara-C@HSPC-Lipo treatment induces apoptosis and differentiation and inhibits the oncogenic pathways. Finally, we verify that HSPC liposomes are safe in mice. This study provides a method for targeting bone marrow and treating leukemia.

Flexible wearable devices for health monitoring require continuous wear throughout the day, making flexible pressure sensors a critical component that has attracted significant attention. Polyacrylamide (PAM) and polyvinyl alcohol (PVA) were used as hydrogel substrate materials to fabricate wearable devices with on-the-go wearability. Helical carbon nanotubes (HCNTs) were employed as conductive fillers, with silver nanoparticles (AgNPs) deposited on their surface to enhance conductivity. The conductive HCNT/AgNPs fillers bonded with the PVA/PAM substrate via metal–hydrogen bonds, metal complexes, and Ag–O bonds. This bonding enhanced the binding strength of the gel and accelerated polymerization. Pressure sensors packaged within the hydrogel exhibited high sensitivity of 0.118 kPa –1 to minor deformations and high sensitivity of 0.0141 kPa –1 to regular deformations, providing a flexible pressure sensor with high sensitivity and fast response. This innovation delivers a highly sensitive and fast-responding flexible pressure sensor, paving the way for advanced flexible wearable electronic devices.

Glioblastoma (GBM) is a highly invasive malignancy with a poor prognosis, primarily attributable to its diffuse infiltration into adjacent brain tissue, thereby complicating effective surgical resection. Current imaging modalities often struggle to accurately identify tumor boundaries. Here, we identify general control non-repressed protein 5 (GCN5) as a promising molecular target for GBM imaging, as it is expressed in GBM lesions within brain tissue, and its expression levels are significantly correlated with GBM grading. We develop a dual-modal probe with a particle size of 20 nm, capable of efficiently traversing the blood-brain barrier (BBB) to target GCN5 through adsorptive-mediated transcytosis (AMT). The probe employs dendrimers (Den) as carriers, which are loaded with a small molecule inhibitor specifically designed to target GCN5. This probe enhances the preoperative delineation of GBM boundaries using magnetic resonance imaging (MRI) and facilitates intraoperative fluorescence image-guided surgical procedures. Our work introduces a promising tool for boundary delineation, offering new opportunities for the precise resection of GBM.
