“…Among them, the adsorption method has emerged as one of the most promising techniques for pre-concentration of REEs, owing to the facile operation, organic solvent-free, and high adsorption efficiency. Recently, many kinds of materials have been proposed to be used for the removal of REEs from aqueous solutions, such as covalent organic frameworks, modified silica gels, super-cross-linked polymers, and some other porous nanoparticles. − Compared to these popular materials, the ion-imprinted polymers (IIPs) exhibit excellent advantages in terms of environmental friendliness, toxicity, and production costs. − …”

Selective recognition and separation of rare-earth elements (REEs) is considered a real challenge for the RE industry. In this work, two dual-site ion-imprinted polymers (IIP-AM and IIP-MAA) were synthesized via a radical copolymerization method for the removal of La(III) from aqueous solutions. The structures of samples were characterized and confirmed with various kinds of techniques, including IR, X-ray diffraction, field emission scanning electron microscopy, Brunauer–Emmett–Teller, thermogravimetry analysis, and X-ray photoelectron spectroscopy (XPS). Adsorption studies reveal that the pseudo-second-order kinetic model and the Langmuir isotherm model were well-fitted with the adsorption of La(III), showing high adsorption capacities of 45.65 and 50.05 mg/g for IIP-AM and IIP-MAA, respectively, after 120 min at pH = 5.5 and 25 °C. Impressively, the fabricated IIPs possess remarkable selectivity between La(III) and other REEs, as well as excellent reusability after five successive adsorption–regeneration cycles with less than 9% reduction of capacities. The adsorption mechanism indicates that the surface complexation and electrostatic attraction contribute to the adsorption of La(III) based on the characterization analysis of XPS, elemental mapping, and energy-dispersive spectrometry, as well as density functional theory calculations. Accordingly, these samples with tailored ion-imprinted cavities and abundant active O sites entirely exhibit the potentials for the selective recovery of REEs from aqueous solutions.

Tissue stiffness has long been known to be a biomarker of tissue pathology. Ultrasound elastography measures tissue mechanical properties by monitoring the response of tissue to acoustic energy. Different elastographic techniques have been applied to many different tissues and diseases. Depending on the pathology, patient-based factors, and ultrasound operator-based factors, these techniques vary in accuracy and reliability. In this review, we discuss the physical principles of ultrasound elastography, discuss differences between different ultrasound elastographic techniques, and review the advantages and disadvantages of these techniques in clinical practice.

“…Owing to their topological structural tunability, high specific area, facile preparation, and designable functionality, MOFs have gained extensive attraction in the field of adsorption. Compared with the other emerging adsorbents, such as covalent organic frameworks, hypercrosslinked polymers, and nanosilica composites, MOFs exhibit excellent advantages in terms of environmental friendliness, toxicity, and production costs. − To date, various well-defined MOFs have been synthesized and utilized in adsorption of REEs. For example, an investigation reported that a Cu-based MOF (HKUST-1) exhibited a remarkable adsorption capacity of 353 mg/g for Ce(III) because of its innate porosity and large specific surface area .…”

The recovery of rare earth elements (REEs) from discharged electronic devices or mineral waste water is highly essential but still facing challenges. In this work, two amino-functionalized carboxyl-UiO-66 (UiO-66-COOH-TETA and UiO-66-(COOH) 2 -ED) prepared via the postmodification method were employed as the adsorbents for Yb(III) capture. The experimental results revealed their superior adsorption capacities of 161.5 and 202.6 mg/g, respectively. Meanwhile, their adsorption processes can be described by the pseudosecond-order kinetic model and Langmuir model. Effects of initial pH and temperature on adsorptions were systematically evaluated, affording an optimal operating condition (i.e., pH of 5.5−6, T of 65 °C, t of 10 h). Moreover, the fabricated materials exhibited great reusability after five adsorption−regeneration cycles. UiO-66-COOH-TETA demonstrated good separation selectivity for Yb(III) over light REEs (i.e., 3.98 of Yb/ Ce, 3.51 of Yb/Nd). Based on the density functional theory calculations and characterization analysis (XPS, Zeta, mapping, and IR), the adsorption mechanisms were mainly attributed to significant electrostatic attraction and strong surface complexation between N and O sites and Yb(III).
