Discharged tetracycline (TC) seriously threatens human health and environmental safety. Herein, we developed a novel 3D flower-on-sheet structure of Zr-metal organic framework adsorbent with the assistant of N,S co-doped carbon dots as heterogeneous nucleation (UiO-67/NSC) for selective and effective removal of TC residue from contaminated water. Functional groups of UiO-67/NSC acts as a tentacle to identify TC molecules, and TC-adsorbed NSC can be separated easily by incorporating in UiO-67 structure. Hierarchical UiO-67/NSC exhibited excellent recognition performance with a wide sensitive range (0.08–20.0 mg/L) and low detection limit (0.063 mg/L) for TC. Particularly, vertically oriented 2D nanosheets in UiO-67/NSC alleviate the diffusion barrier and enhance mass transfer between adsorption sites and TC molecules, endowing it with an ability that can improve the TC adsorption capacity of parent UiO-67 to 427.35 mg/g. UiO-67/NSC with 0D structure has no significant toxic effect on human cells (HepG2 and Caco-2), which demonstrate the prepared hybrid structure is safety in practical application. Our data indicate the great potential of UiO-67/NSC as an innocuous, bifunctional, smart adsorbent for the effective detection and removal of TC residues, and we not only provide a rational design of advanced metal organic framework-based hierarchical adsorbents, but also shed light on an available method to toxic antibiotic residue recognition and water remediation.

The contradiction between the strength and ductility of metallic materials is a major scientific problem that has been researched for a long time. Dual-phase equiatomic and non-equiatomic Ti-Zr-Nb-Ta high-entropy alloys (HEAs) with super-high strength and excellent ductility have been successfully developed via mechanical alloying (MA) combined with spark plasma sintering (SPS) technology. This is adjusted by altering the atomic ratios of the different phases. X-ray diffraction (XRD) and transmission electron microscopy (TEM) were performed to confirm the dual-phase microstructure. After the SPS process, the average grain size of the aforementioned equiatomic Ti 25 Zr 25 Nb 25 Ta 25 HEAs (134 ± 50 nm) evaluated by electron back-scattering diffraction (EBSD) is smaller than that of the Ti-Zr-Nb-Ta HEAs (150 µm), which were fabricated using arc melting. According to the Hall-Petch formula, the grain boundary strengthening contribution in the Ti-Zr-Nb-Ta system is 33-fold higher than those fabricated using the arc-melting process. When the alloy phase comprises the equivalent dual-phase, equiatomic Ti 25 Zr 25 Nb 25 Ta 25 HEAs have good comprehensive performance compared to non-equiatomic Ti-Zr-Nb-Ta HEAs prepared using the same process. The yield strength of equiatomic Ti 25 Zr 25 Nb 25 Ta 25 HEAs (2212 ± 38 MPa) is two-fold higher than that of Ti-Zr-Nb-Ta HEAs (1100 ± 90 MPa) fabricated via arc melting. This can be attributed to the ultra-fine grain size. Notably, the equiatomic Ti 25 Zr 25 Nb 25 Ta 25 HEAs possess approximately the same biocompatibility as commercial pure Ti (CP-Ti), indicating that the equiatomic Ti 25 Zr 25 Nb 25 Ta 25 HEAs are provided with a possibility as an advanced biomaterial for the applications of the medical field.

For the first time, a microwave-assisted synthesis approach was used to prepare an amino-functionalized Zr-based metal–organic polyhedron (denoted as MW-ZrT-1-NH 2 ). The reaction time was shortened from 12 h to 2 min when compared to the traditional solvothermal method, resulting in crystalline products with good yield and purity. Herein, MW-ZrT-1-NH 2 was utilized as a photocatalyst for the catalytic reduction of Cr(VI) under visible-light irradiation. The results revealed that MW-ZrT-1-NH 2 exhibits better photocatalytic performance for Cr(VI) reduction. Furthermore, a plausible photocatalytic mechanism was proposed via electron spin resonance (ESR) measurements and radical trapping tests.

Due to the non-degradable of heavy metal, adsorption has been extensively applied to abatement it. Most studies were focused on uptake metal ions via electrostatic attraction and ion exchange, and load molecule H 3 AsO 4 from strongly acidic wastewater was still challenging. To solve the problem, bimetallic La–Zr MOFs was facilely fabricated in this work, and the fcu topology structure of La-Zr MOFs was remained well under the investigate crystallization time and crystallization temperature. However, the crystallinity of the obtained La-Zr MOFs was influenced by the synthesized factors. The obtained La–Zr MOFs was employed as adsorbent to removal Cr(VI) and As(V), and the performance was evaluated by the batch experiment. The result indicated that the adsorption performance of Cr(VI) and As(V) was positively correlated with the crystallinity , and the optimal sample was 1LaUN 12 . From the XPS characterization, it was found that H 3 AsO 4 was successfully uptake over 1LaUN 12 surface, and the maximum monolayer adsorption capacity was 83.40 mgH 3 AsO 4 /g via ligand exchange and coordination reactions with La−OH and Zr−OH. In addition, the sample 1LaUN 12 also exhibited the excellent Cr(VI) load performance, and the maximum monolayer adsorption capacity of Cr(VI) was 222.5 mg/g. Above 40% Cr(VI) was reduced to Cr(III) by amino groups, and immobilized over the surface of 1LaUN 12 . Eventually, 1LaUN 12 displayed a good structural stability in the acidic medium, which was in favor of removing Cr(VI) and As(V) efficiently from strongly acidic solutions.

Anti-cyclic citrullinated peptide (anti-CCP) antibodies are key biomarkers for rheumatoid arthritis and vital for its early diagnosis and monitoring. Conventional chemiluminescence immunoassays (CLIA) rely on streptavidin-functionalized magnetic beads (SA-MBs), which suffer from limited binding capacity and require labor-intensive chemical conjugation steps. Here, we report a MBs carrier modified with zirconium (Zr)-based metal-organic frameworks (MB@MOF), enabling rapid and efficient SA functionalization via one-step physicochemical adsorption. Compared to the conventional EDC/NHS method, our approach shortens the modification time by at least sixfold and eliminates the need for chemical crosslinkers. The MB@MOF carrier was constructed by anchoring Zr-MOF nanoparticles, synthesized with TCPE as the organic ligand, onto MBs. This carrier supports stable and dense SA loading while preserving native SA activity, thereby allowing highly sensitive detect anti-CCP antibodies. The developed MB@MOF carrier-based CLIA method achieved a detection limit of 0.1 RU/mL and a linear range of 0.5–200 RU/mL. Clinical validation using 36 clinical serum samples showed strong agreement with results from standard clinical analyzers, achieving an overall diagnostic accuracy of 91.7 %. This strategy significantly simplifies the assay workflow and holds strong potential for high-performance and rapid diagnostics of rheumatoid arthritis in clinical application.

Mn 2 O 3 -Na 2 WO 4 /SiO 2 is considered as the most promising catalyst for the oxidative coupling of methane (OCM) process; however, it only has a better catalytic performance over 800 °C. To improve its low-temperature performance, an attempt has been made to modify the Mn 2 O 3 -Na 2 WO 4 /SiO 2 catalyst using TiO 2 , MgO, Ga 2 O 3 , and ZrO 2 . Among the synthesized catalysts, the TiO 2 -modified Mn 2 O 3 -Na 2 WO 4 /SiO 2 catalyst shows markedly improved low-temperature OCM performance, achieving a high CH 4 conversion of ~23% and a good C 2 -C 3 selectivity of ~73% at 700 °C (the catalyst bed temperature), along with promising stability for at least 300 h without signs of deactivation. In comparison with the unmodified Mn 2 O 3 -Na 2 WO 4 /SiO 2 catalyst, the TiO 2 modification results in significant improvement in the low-temperature activity/selectivity, whereas the MgO modification has almost no impact and the Ga 2 O 3 and ZrO 2 modifications have a negative effect. The X-ray diffraction (XRD) and Raman results reveal that the formation of a MnTiO 3 phase and a MnTiO 3 -dominated catalyst surface is crucial for the improvement of the low-temperature activity/selectivity in the OCM process.

The great challenge in capturing harmful volatile organic compounds (VOCs) using Metal-Organic-Frameworks (MOFs) materials still rely on rationally modifying its appreciable microporous character in hydrostable structure. Defected structure in MOFs might be very beneficial for creating expected engineering adsorbent. In this study, defect-engineering UiO-66 via imparting acetic acid (HAc) as an interfering agent was successfully fabricated by a simple hydrothermal method. The physicochemical properties of the obtained materials were intensively ascertained and identified through a series of applicable characterizations. By the proper participation of tuning concentration of HAc (HAc/TAc = 24, molar ratio), the obtained adsorbent UiO-66–1.0HAc was endowed with the highest adsorption capacity for benzene (367.13 mg g −1 , 25 °C) in the known UiO-66 materials, which was 41.9% higher than that of the non-defected UiO-66. With a higher optimized added amount of HAc (HAc/TAc = 48, molar ratio), the adsorption capacity of UiO-66–2.0HAc to toluene achieved the highest capture values (410.21 mg g −1 , 25 °C), which boosted 93% compared with the original counterpart. This demonstrated improvement was ascribable to the imparted structural defect-engineering derived from the missing-linkers of MOFs increasing the unsaturated adsorption site and concomitant enlarged structural properties of the resultant material. By identifying the DIH (Difference in adsorption heat), the obtained maximum adsorption selectivity of UiO-66–1.0HAc to toluene/water was further enhanced to 64.4, which was 3.7 times the original UiO-66, owing to the existed defect-engineering in adsorbents, indicating the potential differential competitive adsorption effect for benzene and toluene under humid conditions.

One-dimensional mesoporous Zr/La bimetallic hydroxide fibers (ZLFs) were prepared for the first time, by one-step electrospinning and high-pressure steam heat-treatment method, and they were used for effective removal of phosphate. The as-obtained fibers had a homogeneous composition and a large surface area, and they benefited from the high-pressure steam heat-treatment. Optimum heat-treatment conditions were confirmed, and the special hydrolysis mechanism in fibers and the Zr/La hydroxides formation process were analyzed. ZLFs with maximum surface area of 233.31 m 2 /g were obtained at a Zr/La mole ratio of 0.4:0.6. Influence of the Zr/La mole ratio of fibers on the adsorption property was examined; an impressive phosphate adsorption performance was observed with saturated adsorption capacity reaching 453.63 mg/g at a Zr/La mole ratio of 0.5:0.5. Notably, the ZLFs exhibited great anti-interference abilities against co-existing ions and pH values, along with good recycling performance. In summary, the ZLFs, produced via an easy method, with outstanding adsorption performance and high reusability, have great potential as adsorbents in the phosphate adsorption field.

To lower the reaction temperature and enhance the waste incorporation rate of ZrSiO 4 , this study developed a novel low-temperature synthesis strategy. MgF 2 was used as a mineralizer to optimize the synthesis of ZrSiO 4 . Ceramics are successfully prepared by sintering at 1000 °C for 6 h. The role of MgF 2 in promoting the reaction is also investigated. At 1000 °C, MgF 2 reacts with SiO 2 to form amorphous Mg 2 SiO 4 . The Mg 2 + ions released in this process promote the phase transformation from m-ZrO 2 to t-ZrO 2 . The t-ZrO 2 then reacts with SiO 4 4- , thereby forming ZrSiO 4 . Under the same conditions, Nd x Zr (1-x) SiO 4 ceramic waste forms are synthesized for the immobilization of Nd 2 O 3 , which simulates high-level radioactive waste. XRD results show that a single-phase zircon structure is maintained when x ≤ 0.35. However, when x > 0.35, a small amount of Mg 2 SiO 4 is detected as a secondary phase. This indicates that some SiO 2 remains unreacted, and part of the Nd 2 O 3 is not incorporated into the crystal structure. Based on these findings, the sample with the maximum solid solution (x = 0.35) is selected and combined with lead-containing borosilicate glass to produce glass-ceramic waste forms. Leaching tests show that the normalized release rate of Nd 3+ gradually decreases as the glass content increases. With a glass content of 90 wt%, the material exhibits outstanding aqueous durability, as evidenced by a negligible Nd 3+ leaching rate of merely 1.57 × 10 −6 g·m −2 ·d −1 after 2 8 days. In conclusion, MgF 2 acts as an effective mineralizer, enabling a substantial reduction in both the synthesis temperature and duration required for ZrSiO 4 formation.

Solar-driven calcium-looping offers a promising pathway for efficient storage and utilization of concentrated solar energy. However, the large-scale application of calcium-based heat carriers is hindered by low solar absorptance, poor sintering resistance, and slow reaction kinetics. Moreover, the energy conversion characteristics and particle behavior under direct irradiation remain poorly understood. In this study, Mn-Zr co-doped CaO composite particles were synthesized via an extrusion-spheronization method, achieving high absorptance, strong sintering resistance, and rapid reaction kinetics. Specifically, the co-doping of Mn and Zr significantly enhances absorptance to 67.7% while effectively reduces cracking. The stable framework of CaMnO 3 and CaZrO 3 maintains abundant mesoporous channels and suppresses sintering. The composite particles exhibit outstanding cycling stability, maintaining an energy storage density of 1148 kJ/kg after 40 cycles with only 22.9% degradation, far outperforming pure CaO materials (64.9% degradation after 20 cycles). Direct irradiation experiments confirm their high solar-thermal conversion efficiency, with particle temperature within the light spot reaching 1600 °C in 3 s. The irradiation-induced particle inhomogeneous sintering mechanism was preliminary proposed. Meanwhile, the effect of non-uniform irradiation on energy storage characteristics and particle behavior is revealed. Non-uniform irradiation led to localized hotspots and increased thermal stress, which aggravated particle breakage and sintering within the light spot.

Half-Heusler alloys, which possess the advantages of high thermal stability, a large power factor, and good mechanical property, have been attracting increasing interest in mid-temperature thermoelectric applications. In this work, extra Zr-doped TiZrxNiSn samples were successfully prepared by a modified solid-state reaction followed by spark plasma sintering. It demonstrates that extra Zr doping could not only improve the power factor on account of an increase in the Seebeck coefficient but also suppress the lattice thermal conductivity originated from the strengthened phonon scattering by the superlattice nanodomains and the secondary nanoparticles. As a consequence, an increased power factor of 3.29 mW m–1 K–2 and a decreased lattice thermal conductivity of 1.74 W m–1 K–1 are achieved in TiZr0.015NiSn, leading to a peak ZT as high as 0.88 at 773 K and an average ZT value up to 0.62 in the temperature range of 373–773 K. This work gives guidance for optimizing the thermoelectric performance of TiNiSn-based alloys by modulating the microstructures on the secondary nanophases and superlattice nanodomains.

Mg/Zr/Nb tri-doping jointly stabilizes Ni-rich layered cathodes under harsh operating conditions. • Tri-doping reduces Li + /Ni 2+ mixing and stabilizes the transition-metal layer and oxygen framework. • MZN-NCM delivers excellent cycling stability at room temperature, high temperature, and high cutoff voltage. • Mg/Zr/Nb co-doping improves charge transfer and Li + diffusion, enhancing the durability of Ni-rich cathodes. Ni-rich layered cathode materials (LiNi x M 1-x O 2 , x ≥ 0.8) offer high capacity and high energy density, but their cycling stability severely suffers from Li + /Ni 2+ cation mixing, H2-H3 phase-transition strain, interfacial side reactions, and sluggish Li + transport, especially under harsh conditions such as elevated temperature and high cutoff voltage. In this work, a Mg/Zr/Nb tri-doping strategy is proposed to construct Li(Ni 0.9 Co 0.05 Mn 0.05 ) 0.97 Zr 0.01 Mg 0.01 Nb 0.01 O 2 (MZN-NCM) cathode for synergistic stabilization under different operating conditions. The results show that Mg/Zr/Nb co-doping regulates the Ni valence distribution, reduces Li + /Ni 2+ cation mixing, enhances the stability of the transition-metal layer and oxygen framework, and suppresses interfacial side reactions and CEI degradation during cycling. MZN-NCM retains 90.1% of its capacity after 100 cycles at 25 °C and 89.8% at 60 °C, compared with only 59.8% and 41.7% for Pristine-NCM, respectively. Under a high cutoff voltage of 4.5 V, MZN-NCM also maintains a higher capacity retention of 87.7% after 100 cycles. Moreover, kinetic and interfacial chemical analyses indicate that multielement doping improves both charge-transfer behavior and Li + diffusion, enabling a synergistic enhancement of structural stability, interfacial stability, and ion transport. This work demonstrates that Mg/Zr/Nb synergistic doping is an effective material-design strategy for extending the applicable operating conditions of Ni-rich cathodes.
