Ferroelectric materials with a switchable polarization are appealing for optoelectronic applications because of their above-bandgap photovoltage with a potential to exceed the Shockley-Queisser limit efficiency within classic p-n junctions. However, the intrinsic photovoltaic current in ferroelectrics remains far below the junction ones by orders, hindering their practical applications. Here we report an extremely large photovoltaic current density of 130 mA cm −2 with a photovoltage of 1.31 V under 375 nm light illumination in single-domain lead titanate films. Its photoresponsivity surpasses all available ferroelectric materials by two orders of magnitude. Systematic investigations reveal that an interfacial Ta dopant layer during solution epitaxy drives a polarization converting of the film via the flexoelectric effect, where surface charged Pb vacancy layer was generated for polarization screening. These two layers produce a p-i-n structure throughout the film, accounting for the ultrahigh photovoltaic response. Furthermore, a self-powered X-ray detector made of such film was explored to achieve a sensitivity of 4.73 C Gy air −1 cm −3 , three orders of magnitude higher than that of commercial amorphous Se detectors. Our findings may pave the way for exploring novel detection and imaging devices based on ferroelectric materials.

The uncontrolled disposal of Tl(I) waste comes at a significant economic and environmental cost because of the acute toxicity and high mobility. To resolve the aggregation problem for most reported MnO 2 based adsorbent materials which significantly affected the adsorption efficiency, porous zwitterionic ammonium propyl sulfonate (zw) polyacrylamide hydrogel (PAAm) has been fabricated to disperse nano-MnO 2 as a support. The developed nano-MnO 2 @PAAm-zw exhibited a specific surface area of 5.06 m 2 /g and a pore diameter of 23.8 nm. particularly amenable to removal of Tl(I) for environmental remediation. The factors, including adsorbent MnO 2 incorporation, feeding amount, adsorption time, pH of the solution, Tl(I) initial concentration and existence of competing cations that governing the adsorption performances were fully elucidated. The maximal removal capacity Q e reaches up to 336.5 mg (Tl) g −1 (MnO 2 ) with 99.92 % elimination efficiency and a low residue of 4.5 μg L −1 . The materials exhibit an astonishing robustness against nature matrix and high concentration of cations with adsorption capacity being 928.6–41.43 times larger than various competing counterparts for lab-made and mineral samples, representing the state-of-the-art level of adsorbents. The adsorbent can be regenerated at least five times retaining 86.0 % of original efficiency. A novel concerted mechanistic pathway of retention mainly associated with re-dox reaction is possible. These features offer great potentials for selective and deep elimination of total thallium in water samples.

The clinical treatment of bone defects includes allogeneic bone transplantation and autologous bone transplantation. However, they all have their own limitations, and the scope of application is limited. In recent years, bone tissue engineering scaffolds based on a variety of materials have been well developed and achieved good bone regeneration ability. However, most scaffold materials always face problems such as high biotoxicity, leading to inflammation and poor bioactivity, which limits the bone regeneration effect and prolongs the bone regeneration time. In our work, we prepared hydroxyapatite, erythropoietin (EPO), and osteogenic growth peptide (OGP) codoped type-I collagen (Col I) polypeptide nanofiber membranes (NFMs) by electrostatic spinning. In cell experiments, the composite NFMs had low cytotoxicity and promoted osteogenic differentiation of rat bone marrow mesenchymal stem cells. Quantitative real-time polymerase chain reaction and alkaline phosphatase staining confirmed the high expression of osteogenic genes, and alizarin red S staining directly confirmed the appearance of calcium nodules. In animal experiments, the loaded hydroxyapatite formed multiple independent mineralization centers in the defect center. Under the promotion of Col I, EPO, and OGP, the bone continued to grow along the mineralization centers as well as inward the defect edge, and the bone defect completely regenerated in about two months. The hematological and histological analyses proved the safety of the experiments. This kind of design to promote bone regeneration by simulating bone composition, introducing mineralization center and signal molecules, can shorten repair time, improve repair effect, and has good practical prospects in the future.

Objective To investigate the cause of markedly elevated cardiac troponin I (cTnI) levels that were inconsistent with the clinical presentation in an 18-year-old male patient with bradycardia. Methods Serial dilution analysis, heterophile antibody blocking test (HBT), polyethylene glycol 6000 (PEG6000) precipitation, and recovery rate calculation were performed on the patient samples, and the experiments were repeated three times. Additionally, continuous monitoring of cTnI, cardiac troponin T, myoglobin, creatine kinase (CK) and CK-MB was conducted on the patient. The recovery rate in the control group was derived from 20 troponin-positive patients. Results The serial dilution test showed good linearity. After HBT treatment, the cTnI concentration was 3744 ng/L, while the control tube was 4024 ng/L, showing no significant change. In contrast, cTnI decreased markedly to 142 ng/L after PEG6000 precipitation. The recovery rate was only 5.61%, which was significantly lower than the mean recovery rate of 53.33% observed in the control group. Conclusion The patient was ultimately diagnosed with falsely elevated cTnI caused by macrotroponin interference. This case suggests that when laboratory results are inconsistent with clinical findings, the possibility of analytical interference should be carefully considered, and effective communication between the laboratory and clinicians is essential to avoid misleading diagnostic and therapeutic decisions.

A simple fluorescence method to quantitatively monitor malachite green (MG) was introduced based on the conformation switch effect of MG-aptamer (Apt) and the fluorochrome of SYBR Green I (SGI). SGI can embed in the stem-loop structure of Apt to produce fluorescence. However, the fluorescence will be quenched when MG is introduced because of the specific binding of Apt to MG. Under the optimal conditions, the fluorescence method displayed excellent linear relationship between the fluorescence quenching efficiencies and the MG concentrations ranging from 0.02 μmol L −1 to 1.0 μmol L −1 . The detection limit of the method was 0.67 μg kg −1 (3 α / κ , n = 9) which is lower than the limit (1 μg kg −1 ) specified in the national standard of China (GB/T 19857–2005) and the limit (2 μg kg −1 ) specified by the European Food Safety Authority (EFSA, 2016). Excellent recoveries between 87.1% and 106.9% tested by spiking standards were achieved with RSD less than 6.4%. The data were confirmed by the method of HPLC, and the results proved that the established fluorescence method could be used for the rapid detection of MG in fish with high accuracy and sensitivity.

The development of effective Vis-sensitive photoinitiators for light-emitting diode (LED) polymerization is still an emerging challenge as LEDs are being developed into the predominant light sources. In this work, a series of new functionalized photoinitiators, containing thioxanthones and oxime-esters as functional groups, was designed and straightforwardly synthesized in two steps. The structures of the photoinitiators were studied using 1H NMR, 13C NMR, and high-resolution mass spectrometry. The conclusion of the photophysical properties indicated that the long wavelength absorptions from 360 nm to 405 nm made the investigated thioxanthone derivatives quite appealing as a valuable photoinitiator under UV-Vis LEDs. The structure–reactivity relationship was also studied in detail through real-time FTIR spectroscopy. A possible photolysis mechanism was expected based on further photolysis and online 1H NMR activities. With a proper molecular design, the new functionalized photoinitiators were synthesised straightforwardly and they displayed more advanced initiation abilities than their parent thioxanthone.

Photocatalytic oxidation of gaseous heavy metals is an efficient approach to alleviate energy crises and environmental pollution. In this study, a novel two-step solvothermal method was designed to synthesize reduced graphene oxide (rGO)-modified bismuth oxyhalide (BiOX, X = Cl, I, Br) nanosheets. The modification of rGO led to the significant enhancement in the specific surface area of BiOX nanosheets, reduction in the bandgap, improvements in the light absorption range and intensity, acceleration in the photogenerated carrier separation rate, and reduction in the photogenerated electron − hole complexation. Furthermore, both O 2 – and OH were demonstrated to be active species in the reaction. Owing to these achievements, all samples displayed significantly improved photocatalytic performance. Furthermore, the rGO-modified samples exhibited excellent stability and maintained the highest mercury removal efficiency after several cycles. However, the samples prepared in this research displayed a high level of moisture resistance. These characteristics of BiOX-based materials make them potential candidates for the photocatalytic removal of heavy metals from industrial waste gases.

The reactive iodine species may exhibit significant impacts on many global atmospheric issues and the I • /I 2 •− radicals play key roles for inducing the formation of these reactive iodine species. However, the current understanding on the formation of I • /I 2 •− radicals in atmospheric aqueous aerosol is still quite limited. The results reported herein suggest that I • /I 2 •− can be produced simultaneously in aqueous aerosol by several sunlight-driven photochemical pathways including direct photo-dissociation of soluble organic iodine (SOI) at rates of 0.10–1.34 × 10 −9 M ns −1 and 0.99–5.68 × 10 −7 M μs −1 , • OH-mediated oxidation of I − at 0.03–1.41 × 10 −8 M ns −1 and 0.05–4.10 × 10 −6 M μs −1 , and 3 DOM ⁎ -induced oxidation of I − at 1.57–1.65 × 10 −9 M ns −1 and 0.99–5.68 × 10 −7 M μs −1 for generation of I • and I 2 •− , respectively. Meanwhile, the pathway of e aq − -initiated stepwise reduction of IO 3 − to I 2( aq ) and further photolyzed into I • plays negligible role in formation of I • /I 2 •− due to the low reaction rates and severe quenching effect of e aq − by dissolved O 2 . Our work presented the new data on mechanism and kinetics for comprehensive elucidation of I • /I 2 •− formation in coastal atmospheric aqueous aerosol and would help to better understand the transformation mechanism of iodine species, pathways of iodine cycling and the associated environmental impacts involving atmospheric reactive iodine radicals.

Exposed collagen on the diseased vessel wall is crucial for arterial thrombosis. The currently developed antithrombotic drugs mostly target blood components such as platelets and suffer from the risk of bleeding. Therefore, anticollagen therapy of covering the collagen surface was proposed as an alternative in our previous study, and an antithrombotic peptide LWWNSYY was designed and validated. However, its application was hindered due to the poor water solubility. In the present study, in order to develop a novel antithrombotic peptide with enhanced water solubility, redesigning of LWWNSYY to LEKNSTY using the EK pattern was proposed. Improved solubility was obtained for LEKNSTY. Moreover, the binding of LEKNSTY on the collagen surface was confirmed by molecular docking, molecular dynamics simulations, and experimental validation. A Kd of 0.91 ± 0.44 μM was observed. The effective inhibition of platelet adhesion on the collagen surface by LEKNSTY was demonstrated at an IC50 of 2.48 ± 0.59 μg/mL. Therefore, the successful design of the antithrombotic peptide LEKNSTY was confirmed, which would facilitate the research into the interface involving thrombus and the development of antithrombotic agents.

Natural materials that are economical and environmentally benign are being explored as adsorbent bases for recovering Au(I) from thiosulfate solution via an efficient grafted functional group. In this work, natural vermiculite (VE) modified with triphenylphosphine oxide (TPPO) was used to adsorb Au(I) from thiosulfate solution, and it's gold recovery performance and adsorption mechanism. Fourier transform infrared spectroscopy , scanning electron microscopy–energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy and nitrogen adsorption were used to characterize the adsorbents. TPPO-modified VE (VE-TPPO) showed improved gold adsorption ability at a pH of approximately 10, thiosulfate concentration of approximately 0.1 mol/L and temperature of approximately 25 °C. More than 95% of Au(I) could be recovered, and the loading capacity of Au on VE-TPPO increased with decreasing adsorption temperature, reaching an amount of 4.22 kg/t after once adsorption. TPPO was adsorbed on vermiculite through cationic-π bonds. Au(I) was adsorbed on VE-TPPO by a ligand-exchange mechanism involving charge transfer between P O groups and Au(I). Moreover, the interaction mechanism between TPPO and Au(I) was further validated by density functional theory calculations. The use of natural materials with low cost and environmental impact can make the process of leaching gold with thiosulfate safer and cleaner.

In recent years, the light source for photopolymerization technology is evolving from energy-hungry mercury lamps to the safer light-emitting diodes (LEDs), and it is urgent to develop new photoinitiator adapted to the photopolymerization system with LED light source. Some acyldiphenylphosphine oxide photoinitiators have been designed and developed for LED light source, but their application is severely limited in the fields of food packing, medical equipment, environmentally-friendly product etc. due to their high mobility in photocured polymers. In this study, eight acyldiphenylphosphine oxide molecules (DAPO-1 ∼ DAPO-8) were synthesized by introducing large molecular weight groups and their UV–visible absorption, photodegradation quantum yield, photopolymerization properties, mobility and solubility in monomer were determined. Thereinto, photoinitiators show lower mobility than TPO, the photoinitiator commonly used in industry, as well as good solubility in monomers and excellent photopolymerization performance. Therefore, they can serve as potential substitutes for commercial TPO, especially in the application of low-migration photocurable system.

The article describes the development of a hetro-core optical fiber sensor structure based on localized surface plasmon resonance (LSPR) for the detection of cardiac troponin I (cTnI) solution. This was accomplished by fabricating a single-mode fiber - multimode fiber - single-mode fiber (SMS) structure. Then, fiber structure is immobilized with gold nanoparticles (AuNPs) and cerium oxide nanoparticles (CeO2-NPs) to improve its sensing capabilities. An UV-Vis spectrophotometer and a high-resolution transmission electron microscope (HR-TEM) are used to determine the morphology of synthesized nanoparticles. Scanning electron microscopy (SEM) is used to examine the state of immobilized NPs on the surface of sensing region. The developed sensor probe has a linear range of 0 to 1000 ng/mL cTnI, a sensitivity of 3 pm/(ng/mL), and a limit of detection (LoD) of 108.15 ng/mL. In real time, the proposed sensor will be used in a practice to detect acute myocardial infarction (AMI).
