It is urgent to selectively enrich trace phosphorylated proteins or peptides from complex biological sample for mass spectrometry (MS)-based phosphoproteomics. In this study, a novel immobilized metal affinity chromatography (IMAC) material with DOTA(1,4,7,10-tetraazacyclododecane N, N′, N′′, N′′′-tetra-acetic acid) coated on the surface of TiO 2 nanomaterials and functionalized with the metal ion Zr 4+ (TiO 2 @DOTA-Zr) has been synthesized successfully to improve the enrichment specificity and sensitivity for phosphopeptides. TiO 2 nanomaterials were chosen as a support matrix, which will offer a high specific surface area to enhance the amounts of immobilized Zr 4+ ions and will provide an additional selectivity for the special enrichment of phosphopeptides. Also, the introduction of DOTA will endow a stronger binding interaction between the Zr 4+ ion and DOTA to reduce the loss of the metal ion Zr 4+ during sample loading and washing steps. The novel TiO 2 @DOTA-Zr nanohybrids exhibited higher sensitivity and selectivity for phosphopeptides from the standard protein digests, the tryptic digests of nonfat milk and human serum, showing a great selective enrichment capability toward the complicated biological samples.

In this study, a coating of ionic Zr integrated in 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP) metalorganic-like complexes was applied on Mg for corrosion control. HEDP was first immobilized on alkaline pretreated Mg followed by an alternating dip-coating process of Zr ions and HEDP to build a complex coating on Mg. This coating was demonstrated to be homogeneous, compact and with a metalorganic-like framework firmly anchored on Mg. This coating led to reduced corrosion current densities and remarkably suppressed long-term in vitro degradation of Mg in phosphate buffer saline (PBS). This complex coating showed promise for surface modification of Mg in biodegradable applications.

A series of new systems of the SrCe 1- x Ti x O 3 and SrCe 1− x Zr x O 3 (SCT x and SCZ x , x = 0.0–0.1) ceramics have been prepared by the traditional solid-phase methods. The XRD patterns results show that an ABO 3 -type perovskite structure of the SrCeO 3 ceramic can be obtained as x = 0.0. With the increase in Ti 4+ - and Zr 4+ -ions-doping content of x = 0.02–0.1, the SCT x and SCZ x ceramics basically belong to the perovskite phase with the orthorhombic structure of the space group Pmcn (62), and the results of EDS analysis on the proportion of each element can also verify the correctness of the XRD analytical results. In addition, all the microstructures are dense for the SCT x and SCZ x ( x = 0.0–0.1) samples. The fitting results of complex plane impedance verified that the temperature stability of SCT x solid solution ceramics is more suitable for adjusting to the practical application range. Especially, the SCT x ( x = 0.03) ceramics sintered at 1270 °C for 4 h can obtain the relatively excellent dielectric properties of ε r = 50.16, Q × f = 8,940 GHz (at 5.91 GHz), and τ f = + 0.08 ppm/°C.

A series of ultrathin metal intercalated montmorillonite (Mont) nanosheet materials were prepared and characterized for the one-pot cascade conversion of furfural (FAL) to obtain γ-valerolactone (γ-GVL). The coordination of the intercalated metal ions and the hydroxyl groups between the montmorillonite layers leads to an increase in the specific surface area and pore volume of the material, which coupled with the acidity of the metal ions themselves improves the catalytic performance of the material. Thus Zr-Mont-0.1 exhibited optimal catalytic performance with 100% conversion of FAL and 50.4% yield of GVL under mild conditions, and more importantly, the catalyst maintained its good catalytic performance after the fourth use. Meanwhile the number of Lewis and Brønsted acid sites in the Zr-Mont catalyst can be varied by adjusting the zirconium ion concentration. The proposed reaction mechanism provides initial insights into the role of metal-functionalized montmorillonite in catalyzing the reaction. In addition, the ten-fold magnification reaction confirmed the potential industrial application of the catalyst.

Barium strontium zirconate titanate ceramics ((BaSr)(ZrTi)O3-BSZT) with Zr4+ ionic contents of 15 and 20 mol % and Sr2+ ionic contents of 15, 20, 25, and 30 mol % were prepared using a solid-state reaction approach. X-ray diffraction and scanning electron microscopy were used to characterize the lattice structure and morphologies of the ceramics. Permittivity and polarization as a function of temperature were characterized using an impedance analyzer and a Tower–Sawyer circuit. The electrocaloric effect was measured directly and calculated using the Maxwell relation (indirectly). The results indicated that the BSZT ceramics change from a normal ferroelectric to a relaxor ferroelectric with increasing Zr4+ ionic content, which can be further modified by the addition of Sr2+ ionic content. The optimized adiabatic temperature change ΔT obtained is 2.43 K in (Ba0.85Sr0.15)(Zr0.15Ti0.75)O3 ceramics, and ΔT >1.6 K over a wide temperature span of 120 °C was obtained.

Strippable films are extensively utilised for the decontamination of radioactive surfaces because of their cost-effectiveness, ease of operation, and minimal liquid waste. However, traditional strippable detergents are formulated for use at normal ambient temperatures and typically lose their efficacy at low temperatures because of poor performance or excessively long film-forming time. In this study, we have developed an anti-freezing and sprayable AMZW detergent based on acrylic acid (AA), acrylamide (AM), zirconyl chloride octahydrate (ZrOCl 2 ·8H 2 O), and water (H 2 O), which possesses a freezing point of approximately −34 ℃ due to the solvation interaction between Zr 4+ and H 2 O. Even at temperatures as low as −25 ℃, the AMZW detergent can be easily sprayed using a conventional apparatus and rapidly cured into a strippable hydrogel film under irradiation by 365 nm UV LED light (LED@365 nm), household LED panel light, or sunlight. The coordination bond formed between Zr 4+ and the carboxyl group of the polymer chain imparts excellent mechanical properties to the hydrogel while the carboxyl group can complex with uranyl nitrate hexahydrate (UO 2 (NO 3 ) 2 ·6H 2 O)—a radioactive simulant. As a result, the strippable hydrogel film demonstrates high tensile strength (6.1 ∼ 19.3 MPa), excellent flexibility (elongation of 90 ∼ 855 %), moderate peel strength (0.05 ∼ 3 N/cm, room temperature (RT)), and high decontamination efficiency (>91.6 % on stainless steel and glass; >81.3 % on concrete) over a wide range of temperatures (−25 ∼ 25 ℃). This work presents a novel approach for producing anti-freezing, fast-forming, flexible, and high-strength strippable hydrogel films for surface radioactive decontamination at low temperatures.

Stable and durable hydrophobic wood surfaces hold great potential in the wood industry. However, wood tends to absorb water due to the abundant surface hydroxyl groups. A facile and effective approach is proposed here to construct hydrophobic and damage-tolerant wood surface by coordinating the hydroxyl groups with metal ions. By immersing the pristine wood blocks into salt solutions and followed by drying, the modified wood surface exhibits a hydrophobic behavior. In particular, the surface of Zr 4+ ion modified wood (Zr-Wood) demonstrates the most dramatic modification effects. The surface vertical to wood growth direction has a water contact angle of 145°, while the surface along the wood growth shows a water contact angle of 139°. Moreover, the wear resistance and durability are explored and the results prove that Zr-Wood possesses good tolerances against sandpaper abrasions and corrosive solutions. The hydrophilic to hydrophobic transition is ascribed to the formation of metal complexes between ions and hydroxyl groups. Such method is promising for wood preservation and can extend the use of wood.

Swelling is ubiquitous for conventional hydrogels but is not favorable for many situations, especially underwater applications. In this study, an anti-swelling and mechanically robust polyacrylic acid (PAAc)/gelatin composite hydrogel is reported with a rapid gelation process (10 1 s) under mild conditions via the synergy of MXene-activated initiation and zirconium ion (Zr 4+ )-induced cross-linking, without the requirement of external energy input. The MXene is found efficient to activate the chain initiation, while the Zr 4+ is prone indispensable for facilitating the cross-linking of formed polymer chains. The resulting hydrogel exhibits integration of exceptional anti-swelling properties and high mechanical performance at room temperature, thanks to the dense hydrogen bonds between PAAc and gelatin chains that enable an upper critical solution temperature above room temperature. Also, desirable electrical conductivity emerges in the hydrogel due to the simultaneous contribution of MXene and Zr 4+ , allowing stable electrical signal output of the gel upon deformation underwater. As a demonstration, an underwater communicator by harnessing the gel as a sensing module is assembled, which is capable of wirelessly delivering messages to the decoder on the ground via Morse codes. This study provides an exemplary way for the rapid gelation of tough and anti-swelling hydrogels for durable underwater applications.

This work investigates the influence of fluoride ions on the electrochemical behavior and coordination properties of zirconium ions under different molar ratios of fluoride ions to zirconium ions, utilizing a combination of electrochemical and spectroscopic methods. The electrochemical properties of zirconium ions were examined at different fluoride ion contents within NaCl-KCl-ZrCl 4 and NaCl-KCl-K 2 ZrF 6 molten salt systems using cyclic voltammetry (CV), square wave voltammetry (SWV), and the chronopotentiometry (CP). Additionally, the samples underwent analysis through raman spectroscopy. The results demonstrate that zirconium ions reduction behavior is highly sensitive to fluoride ion content, which directly affects their reduction path, while the overall reduction trend remains consistent. Meanwhile, the coordination structure of zirconium ions with anions in molten salts has been modified. As fluoride ions are introduced, the Cl − ions present in the original ZrCl 6 2− complex are progressively replaced, giving rise to new coordination ions (ZrCl x F y n − ). When fluoride ions accumulate to a specific concentration, the formed coordination ions (ZrF x 2− ) have stronger stability to support them avoiding the formation of intermediate valence zirconium ions and be reduced to metallic zirconium via one step. Ultimately, electrodeposition experiments were conducted using fluoride ion and zirconium ion electrolytes at various molar ratios. The findings indicated that the current efficiency enhanced as the concentration of fluoride ions increased, and the volume of cathode deposits also rose with the addition of fluoride ions.

The presence of antibiotics in the environment has attracted considerable attention due to their toxicity. In this study, agricultural waste corn bracts (CBs) modified by zirconium cations were utilized to remove levofloxacin (LEV) from wastewater. Zr-modified CBs exhibited a strong adsorption capacity (Q max = 73 mg/g), and their desorption rate could reach 89% by simply adjusting the pH to 11. FTIR and XPS analyses indicated that the mechanism of LEV adsorption included the complexation between the ketone/carboxyl groups of LEV and the Zr atoms and the π-π electron-donor-acceptor interaction. Zr-modified CBs are economic, effective and nontoxic adsorbents. This material not only removes antibiotics from wastewater but also enables recycling and reuse of agricultural waste.

Due to the role of phosphate (PO 4 3− ) as an indicator of eutrophication pollution, developing low-cost and high-performance approaches to detect it turns to be of great significance. Herein, we developed a highly sensitive and specific colorimetric sensor for PO 4 3− determination via utilizing Zr 4+ to synergistically inhibit the peroxidase-like activity of Fe 3 O 4 nanocubes. The decoration of hydrophilic 3,4-dihydroxyhydrocinnamic acid (DHCA) on Fe 3 O 4 endows it with enhanced ability to catalyze the 3,3′,5,5′-tetramethylbenzidine (TMB) chromogenic reaction. Because of electrostatic interaction, Zr 4+ is easy to be adsorbed onto the negatively charged Fe 3 O 4 -DHCA nanozyme. When PO 4 3− is added, it can interact with Zr 4+ and form a coating on Fe 3 O 4 -DHCA surface, significantly suppressing its peroxidase-mimicking activity. As a result, the TMB chromogenic reaction is seriously inhibited in the presence of PO 4 3− . Based on this strategy, PO 4 3− in the wide scope of 0.066–33.3 μM could be linearly determined, providing a detection limit down to 49.8 nM. Thanks to the strong and specific interaction between Zr 4+ and PO 4 3− , the colorimetric sensor could be employed to detect PO 4 3− with favorable selectivity. Reliable analysis of the target in practical water was also verified by our assay, indicating its great potential as a simple but efficient tool for environmental monitoring.

The immersion method in which metal ions were used to toughen macromolecular chains to avoid the failure of hydrogel synthesis due to the rapid formation of coordination bonds in the gel precursor was often used to develop a robust gel. However, the uneven distribution of ions inside the hydrogel was harmful for its sensing performance by soaking. Herein, a robust polyacrylamide/gelatin/ZrOCl2·8H2O (PG-Zr4+) hydrogel was developed by a straightforward strategy to toughen gelatin chains with Zr4+. The PG-Zr4+ hydrogel held not only a high transparency (73%), robust fracture strength (0.842 MPa), and outstanding toughness (4 MJ m–3) but also fast self-recovery and satisfactory conductivity. Furthermore, the crystallization peak of the PG-Zr4+ hydrogel disappeared at −60 to 25 °C with the introduction of dimethyl sulfoxide (DMSO) as a cryoprotectant; it could still exhibit stable electrical responses to weak stimuli of 1% strain at −20 °C for 24 h. Surprisingly, when simply assembled into a strain sensor with a gauge factor (GF) of 5.817, it was capable of precise real-time monitoring of both subtle pronunciation signals and drastic joint movements. This work opened the door to develop flexible wearable devices with multiple advantages.
