In this work, In-doped LiZnTi spinel ferrites were successfully synthesized at a low temperature (920 °C) using 2 wt% Bi 2 O 3 as a sintering aid. The effects of In 3+ doping concentration on phase formation, microstructure, gyromagnetic properties, and dielectric properties were investigated. Results showed that all samples exhibited a single spinel phase, and grain growth behavior was strongly influenced by In 3+ doping. Although saturation magnetization decreased with increasing In 3+ content, the real part of the magnetic permeability (μ') increased from 117 (x = 0.00) to 170 (x = 0.09), while maintaining low magnetic loss. Meanwhile, the dielectric constant showed an upward trend (ε' increased from 15.88 to 18.50) with minimal dielectric loss. Regarding gyromagnetic properties, the sample with x = 0.06 exhibited a narrow ferromagnetic resonance linewidth (ΔH) of 240.09 Oe. The combination of high dielectric constant and low linewidth suggests promising potential for low-loss microwave ferrite devices.

Solid-state lithium-ion batteries with high safety are the encouraging next-generation rechargeable electrochemical energy storage devices. Yet, low Li + conductivity of solid electrolyte and instability of solid–solid interface are the key issues hampering the practicability of the solid electrolyte. In this research, core–shell MOF-in-MOF nanopores UIO-66@67 are proposed as a unique bifunctional host of ionic liquid (IL) to fabricate core–shell ionic liquid–solid electrolyte (CSIL). In the current design of CSIL, the shell structure (UIO-67) has a large pore size and a high specific surface area, boosting the absorption amount of ionic liquid electrolyte, thus increasing the ionic conductivity. Nevertheless, the core structure (UIO-66) has a small pore size compared to the ionic liquid, which can confine the large ions, decreasing their mobility, and selectively boost the transport of Li + . The CSIL solid electrolyte exhibits considerable enhancement in the lithium transference number ( t Li + ) and ionic conductivity compared to the homogenous porous host (pure UIO-66 and UIO-67). Additionally, the Li|CSIL|Li symmetric batteries maintain a stable polarization of less than 28 mV for more than 1000 h at 1000 µA cm −2 . Overall, the results demonstrate the concept of core–shell MOF-in-MOF nanopores as a promising bifunctional host of electrolytes for solid-state or quasi-solid-state rechargeable batteries.

The accumulation of antibiotics in the environment has caused worldwide concern and photocatalytic processes have shown attractive prospects for the elimination of antibiotics due to its sustainability, cleanliness and efficiency. In this study, a series of self-assembled hollow tubular Zn–In–S photocatalysts (Zn-doped In 2 S 3 , ZnIn 2 S 4 , and ZnS/ZnIn 2 S 4 ) were first designed by one-step sulfidation of Zn/In-MOFs. The as-synthesized microtubular structured Zn–In–S exhibited high surface area(107.61–127.26 m 2 /g), high porosity(0.25–0.52 cm 3 g −1 ) and high degradation rate(≥86%) towards tetracycline within 120 min. Moreover, the photoelectric properties and photocatalytic performance were dependent on the existence of Zn species. Particularly, the optimized hollow microtubular ZnS/ZnIn 2 S 4 composites exhibited ultrahigh photocatalytic degradation rate (>90%) within 1 h solar light irradiation. The kinetic constant reached 0.0379 min −1 , which was 2.96, 2.02, and 5.65 times higher than In 2 S 3 , ZnIn 2 S 4 , and ZnS respectively. The ultrahigh photocatalytic degradation efficiency originated from the formation of direct Z scheme heterojunction between ZnIn 2 S 4 and ZnS. The unique heterojunction enabled the effective separation of electron-hole pairs and the production of highly reactive oxidants (•OH, •O 2 − , h + ). Density functional theory(DFT) demonstrated a higher charge density near the Fermi level and higher affinity towards O 2 molecules, which contributed to the efficient interfacial charge mobility and O 2 activation. The work provides guidance for the modulation of ternary catalysts to maximize the virtues of photocatalytic activity .

In this work, a metal–organic framework MIL-68(In)–NH2 incorporated high internal phase emulsion polymeric monolith (MIL-68(In)–NH2/polyHIPE) was prepared and applied as a solid phase extraction adsorbent for the extraction and detection of trace triazine herbicides in environmental water samples by coupling with HPLC-UV detection. The fabricated material showed good adsorption for simazine, prometryn, and prometon in water samples because of π–π interactions and hydrogen bonding interactions. Under optimal conditions, the maximum adsorption capacity of simazine, prometon and prometryn was 800 μg g−1, 800 μg g−1 and 6.01 mg g−1, respectively. The linearities were 10–800 ng mL−1 for simazine, prometon and prometryn. The limits of detection were 31–97 ng L−1, and the recoveries were 85.6–118.2% at four spiked levels with relative standard deviations lower than 5.0%. The method has a high sensitivity for the determination of three triazine herbicides in environmental water samples.

SnO 2 has been recognized as excellent catalyst towards formate production from electrochemical CO 2 reduction (CO 2 R). However, it is a great challenge to prepare SnO 2 that is stable under the working condition of CO 2 R and the active center of the SnO 2 -based catalyst towards CO 2 R has been illusive. In this work, Sn-In alloy nanoparticles display an InSn 4 intermetallic core and an amorphous In-doped tin oxide shell and a CO 2 -to-formate faradaic efficiency of 94% and a current density of 236 mA cm −2 was achieved at −0.98 V. Operando X-ray absorption and Raman spectroscopy reveal that the In-doped tin oxide shell remains stable under CO 2 R condition. Density functional theory calculations indicate that the In-doped tin oxide results in the formation of oxygen vacancy, stabilized tin oxide shell and exergonic pathway for CO 2 -to-formate, which might account for the high performance of the catalysts towards CO 2 R.

In recent years, Ag-In-Ga-S (AIGS) quaternary quantum dots (QDs) have garnered significant attention as a novel class of environmentally friendly and non-toxic QDs. However, the hydrothermal synthesis method for aqueous QDs has been plagued by issues such as inconsistent size, subpar crystallinity, and low photoluminescence quantum yield (PLQY). Herein, we developed a dual ligand strategy based on the hard and soft acids and bases (HSAB) theory to synthesize aqueous AIGS QDs with an impressive PLQY of up to 64.3%, currently the highest value among hydrothermal-synthesized uncoated I-III-VI QDs. The QDs exhibit better crystallinity, narrow size distribution (3.07 ± 0.31 nm), and remarkable stability. The mechanism underlying this dual ligand strategy was further elucidated, shedding light on the distinct influences of different ligands on the growth of QDs. The high PLQY contributes to the further application of aqueous AIGS QDs in luminescent displays and the field of biology. Meanwhile, this ligand strategy has broad reference significance for efficient preparation of other water-soluble QDs.

A simple two-phase strategy was developed to prepare Cu31S16–CuInS2 heterostructures (HNS) at the oil/aqueous interface, in which the In(OH)3 phase was often obtained in the products due to the reaction between indium ions and hydroxyl ions in the aqueous phase. To prevent the formation of the In(OH)3 phase, citric acid was incorporated into the aqueous phase to assist in the synthesis of uniform carrot-like Cu31S16–CuInS2 semiconductor HNS at the oil/aqueous interface for the first time. By manipulating the dosage of citric acid and Cu/In precursor ratios, the morphology of the Cu31S16–CuInS2 HNS could be tailored from mushroom to carrot-like, and the presence of citric acid played a critical role in the synthesis of high-quality Cu31S16–CuInS2 HNS, which inhibited the formation of the In(OH)3 phase due to the formation of the indium(III)–citric acid complex. The formation mechanism was studied by monitoring the morphology and phase evolution of the Cu31S16–CuInS2 HNS with reaction time, which revealed that the Cu31S16 seeds were first formed and then the cation-exchange reaction directed the subsequent anisotropic growth of the Cu31S16–CuInS2 HNS.

Discovering compounds with anti-cervical cancer effect and clarifying their targets will help promoting the precise treatment of cervical cancer. The present study intended to clarify the effect of osthole on cervical cancer cells, and to explore the possibility of DCLK1 as its target.
Annexin V-PE staining and flow cytometry methods were used to determine cell apoptosis. Meanwhile, apoptosis related biomarkers were probed by immunoblotting. The MTT assay was employed to study the effect of osthole in combined with or without LRRK2-IN-1 (a DCLK1 inhibitor) on cell proliferation.
Then, combination index was determined. To examine the interaction of osthole with DCLK1, molecular docking was carried out. Based on the biological database from cBioPortal, the association between DCLK1 and clinical manifestations of cervical cancer were evaluated. The results showed that
osthole can significantly induce apoptosis of HeLa and Me-180. When combined with LRRK2-IN-1, the effect of osthole on cell proliferation was antagonized, suggesting that it might competitive binding to DCLK1. Furthermore, molecular docking showed that osthole interacts with Val468 residues
of DCLK1 to form hydrogen bonds. The analysis of database showed that DCLK1 frequently mutant and deleted in cervical cancer, and is related to cell survival, tumor progression and recurrence. However, no obvious correlations were found between DCLK1 and lymphatic metastasis/differentiation.
In conclusion, osthole significantly inhibits the survival of cervical cancer cells. It's probably target DCLK1 mechanistically via interacting with Val468. DCLK1 could be a potential therapeutic target for cervical cancer.

Gd 3+ -doped quantum dots (QDs) have been widely used as small-sized bifunctional contrast agents for fluorescence/magnetic resonance (FL/MR) dual-modality imaging. However, Gd 3+ doping will always compromise the FL of host QDs. Therefore, balancing the Gd 3+ doping and the optical properties of QDs is crucial for constructing high-performance bifunctional nanoprobes . Additionally, most paramagnetic QDs are synthesized in the organic phase and need to be transferred to the aqueous phase for bioimaging. Herein, ingeniously designed shell-doped Cu-In-S/ZnS:Gd 3+ QDs have been prepared in the aqueous phase. It has been demonstrated that isolating paramagnetic Gd 3+ from fluorescent Cu-In-S core via doping Gd 3+ into ZnS shell not only avoided the decrease of FL quantum yield (QY), but also ensured the water accessibility of paramagnetic Gd 3+ ions, by which the FL QY and r 1 relaxivity of Cu-In-S/ZnS:Gd 3+ QDs achieved as much as 15.6% and 15.33 mM -1 ·s -1 , respectively. These high-performance QDs with excellent stability, low biotoxicity, and good tumor permeability were successfully applied for in vivo tumor FL/MR dual-modality imaging, and have shown significant potential in the precision detection and diagnosis of diseases.

Two high-sensitivity competitive immune-nanoplatforms based on the inner filter effect (IFE-IN) and magnetic separation (MS-IN) with a positive readout were developed to rapidly detect imidacloprid (IMI) using gold nanoparticles (AuNPs). For IFE-IN, IMI competes with AuNPs-labeled IMI antigens (IMI-BSA-AuNPs) to bind with anti-IMI monoclonal antibody (mAb)-conjugated NaYF 4 :Yb,Er upconversion nanoparticles, which changes the fluorescence signal at excitation/emission wavelength of 980/544 nm. For MS-IN, the immunocomplex of IMI-BSA-AuNPs and magnetic-nanoparticles-labeled mAb (mAb-MNPs) dissociates in the presence of IMI, and the optical density of IMI-BSA-AuNPs at 525 nm increases with the IMI concentration after magnetic separation. Under the optimal conditions, the IMI concentration producing a 50% saturation of the signal (SC 50 ) and linear range (SC 10 − SC 90 ) were found to be 4.30 ng mL −1 and 0.47 − 21.37 ng mL −1 for IFE-IN, while 1.21 ng mL −1 and 0.07 − 10.21 ng mL −1 for MS-IN, respectively. Both IFE-IN and MS-IN achieved excellent accuracy for the detection of IMI in different matrices. The quantities of IMI in apple samples detected by IFE-IN and MS-IN were consistent with the high-performance liquid chromatography results. Graphical abstract For IFE-IN, analyte competes with AuNPs-labeled-antigen to bind with the mAb-conjugated-UCNPs, which changes the fluorescence signal at 544 nm. For MS-IN, the immunocomplex of AuNPs-labeled-antigen and mAb-conjugated-MNPs dissociates in the presence of analyte, and the optical density of AuNPs-labeled-antigen at 525 nm increases with increasing analyte concentration after separation.

Refining the visible light absorption and optimizing the separation of photogenerated electron-hole pairs are pivotal in enhancing the photocatalytic activity of composites. A novel Z-scheme plasma photocatalyst, Ag/Ag 3 PO 4 /In-MOF (A/AP/In), was developed in this study. Experimental results demonstrated that A/AP/In exhibited the highest photocatalytic activity for BPA among all samples tested, achieving complete degradation of 50 ppm BPA within 30 min, as well as its apparent degradation rate was about 11 times higher than that of pure Ag 3 PO 4 and 4 times higher than that of pure In-MOF. The enhanced photocatalytic activity can be mainly attributed to the existence of Z-type heterojunctions and the surface plasmon resonance (SPR) effect induced by Ag nanoparticles , which facilitate efficient migration and separation of photogenerated carriers. Meanwhile, the incorporation of Ag nanoparticles enhances visible light absorption and protects Ag 3 PO 4 from photocorrosion in the composites. Moreover, A/AP/In maintains the large specific surface area of In-MOF and provides abundant reactive active sites. In addition, the photocatalytic performance of A/AP/In was above 90 % after five consecutive cycles confirming its good stability. Overall, this study proposes a novel approach for constructing bifunctional composites with efficient adsorption/catalytic degradation.

I–III–VI quantum dots (QDs) and derivatives (I, III, and VI are Ag+/Cu+, Ga3+/In3+, and S2–/Se2–, respectively) are the ideal candidates to replace II–VI (e.g., CdSe) and perovskite QDs due to their nontoxicity, pure color, high photoluminescence quantum yield (PLQY), and full visible coverage. However, the chaotic cation alignment in multielement systems can easily lead to the formation of multiple surface vacancies, highlighted as VI and VVI, leading to nonradiative recombination and nonequilibrium carrier distribution, which severely limit the performance improvement of materials and devices. Here, based on Zn–Ag–In–Ga–S QDs, we construct an ultrathin indium sulfide shell that can passivate electron vacancies and convert donor/acceptor level concentrations. The optimized In-rich 2-layer indium sulfide structure not only enhances the radiative recombination rate by preventing further VS formation but also achieves the typical DAP emission enhancement, achieving a significant increase in PLQY to 86.2% at 628 nm. Moreover, the optimized structure can mitigate the lattice distortion and make the carrier distribution in the interior of the QDs more balanced. On this basis, red QD light-emitting diodes (QLEDs) with the highest external quantum efficiency (EQE; 5.32%) to date were obtained, providing a novel scheme for improving I–III–VI QD-based QLED efficiency.
