AIE active hydroxycoumarin-anthranilic acid coupled enamine: Sequential detection of Cu2+/S2− ions and live cell imaging application

In this contribution, we designed and developed 7-diethylamino-4-hydroxycoumarin coupled anthranilic acid-based enamine (DHCBA) and its Cu2+ complex (DHCBA-Cu)via a simple synthetic strategy. DHCBA shows solvatochromic effect, aggregation induced emission feature at (80 %) methanol–water mixture and colorimetric as well as fluorescence turn-off sensing features towards Cu2+ ions. The DHCBA-Cu2+ ensemble has been utilized as a turn-on fluorescence sensor for the detection of S2− through a decomplexation approach. The formation of a 1:1 DHCBA-Cu2+ ensemble was further supported by 1H NMR studies, HRMS analysis and Density Functional Theory (DFT) calculation. The detection limit for Cu2+ was found to be 6.5 nM and then the binding affinity and binding stoichiometry of the probe towards Cu2+ ion was calculated using the online BindFit v0.5 supramolecular software. Moreover, the 1:1 stoichiometric ratio between DHCBA and Cu2+ ions were confirmed via single crystal X-ray analysis. The structural analysis of DHCBA-Cu2+ indicates that it forms an interesting one-dimensional coordination polymeric chain-like structure, further transformed into a two-dimensional polymeric network through hydrogen bonding interactions. The reversible on–off–on emission character of the probe, DHCBA was successfully applied for the construction of the IMPLICATION logic gate as well as on-site detection applications using paper strip and cotton-swab tests. Furthermore, the sensing feature of the enamine against Cu2+/S2− ions were validated by intracellular imaging applications.

Examining Dimensionality and Item-Quality of the Eating Disorder Examination Questionnaire in Individuals With Eating Disorders Using Item Response Theory Analysis.

The Eating Disorder Examination Questionnaire (EDE-Q) is a widely-used measure of eating-disorder symptoms. However, inconsistent replication of the subscale structure raises concern about validity. To provide a rigorous test of the EDE-Q's dimensionality and item-quality, we applied modern and classical test theory approaches to data obtained from a large, transdiagnostic sample of people with clinical eating disorders. We analyzed data from 1197 individuals (Mage = 27.9 years, SD = 10.08, 95% female) with various eating disorders, who had been assessed for treatment at a specialized program. Exploratory analyses (including Parallel Analyses), Confirmatory Factor Analyses (CFA) and graded-response Item Response Theory (IRT) analyses, were conducted with Mplus. Factor analyses showed inappropriate fit to the original EDE-Q subscales, as well as for alternative 1,2,3, and 4-factor solutions. Parallel analyses suggested a one-dimensional structure as best fit. IRT analyses showed substantial variability in EDE-Q-item quality and indicated that five items (fear of weight gain, feeling fat, desire to lose weight, importance of weight, importance of shape) were most pertinent to determining severity. The construct validity of the five EDE-Q items was confirmed by a CFA, showing excellent fit. Our results suggest that EDE-Q scores are best interpreted as spanning a one-factor continuum. IRT results suggest that some items are more pertinent than others for determining eating-disorder severity. Results could be useful for establishing short EDE-Q versions, such as a five-item version, which, in turn, would be helpful for measurement-based clinical practice and for data-collection in epidemiological and experimental studies.

Thermo-optic tuning of quasi bound state in continuum in lithium niobate thin film hetero-nanograting

Lithium niobate (LN) is difficult to etch precisely due to its stable physical and chemical properties. In recent years, more and more research has focused on etchless thin film lithium niobate (TFLN). Here, a one-dimensional SiO2 nanograting structure fabricated on lithium niobate on insulator (LNOI) platform is designed in this study. This nanograting can generate one-dimensional diffraction waves. Then quasi-bound state in the continuum (q-BIC) can be introduced by aligning with the waveguide mode supported by the TFLN, which can achieve a high-quality factor and strong field enhancement, thus improving the interaction between light and matter. Furthermore, we validate the polarization characteristics of the nanograting structure, and measure the thermo-optical tuning sensitivity of the device to be 26.67 pm/K. This finding opens up potential avenues for realizing multi-dimensional tunable and dynamic photonic devices.

Enhanced Na-Ion Electrochemical Performance through Cu Doping-Mediated Sb2Se3 Phase Transformation into CuSbSe2 with Improved Kinetics.

This work investigates the influence of structural and electronic modification on the electrochemical performance of conversion and alloying materials. The CuSbSe2, a promising 2D layered conversion-and-alloying material is being investigated with references to parent pristine Sb2Se3 and a doped version of later Sn0.2Sb1.8Se3 for their sodium-ion battery performance. The CuSbSe2 with layered structure is well known to accommodate lattice distortions via inter-layer movement, potentially mitigating distortions brought about by the Alkali ion (Na in this case) insertion. In contrast, the parent conversion-cum-alloying material Sb2Se3 with its one-dimensional crystal structure leads to structural disintegration during battery operation. The Sn-doped analog, Sn0.2Sb1.8Se3, comparatively exhibits enhanced kinetics owing to the reduced long-range order. The 2D layered, CuSbSe2 despite exhibiting2D long-range order exhibits superior electrochemical performance owing to the favorable electronic and structural features. The CuSbSe2 exhibits a reversible capacity of 881 mAh g-1 compared to 516 mAh g-1 for Sn0.2Sb1.8Se3 and 429 mAh g-1 for Sb2Se3, with an improved Coulombic efficiency as well. The transient electrochemical investigations of Electrochemical Impedance Spectroscopy (EIS) and Galvanostatic intermittent titration techniques (GITT) reveal that better performance exhibited by CuSbSe2 may well be attributed to kinetics owing to enhanced diffusion coefficients in the intercalation and conversion regime.

A two-dimensional thin film structure with spectral selective emission capability suitable for high-temperature environments

Spectral selective emission materials, characterized by their high emission efficiency within specific wavelength ranges, play a crucial role in various fields such as infrared stealth and radiative cooling. In this study, leveraging the tunneling effect of ultrathin metal layers and the impedance matching principle, we designed a one-dimensional multilayer thin film structure composed of Mo/Ge/Al. This design successfully achieved spectral selective emission within the 3-14 μm infrared spectrum range, showcasing superior high-temperature infrared stealth capabilities. Research findings indicate that the infrared atmospheric window (ε3-5 μm=0.40, ε8-14 μm=0.30) maintains a low emissivity within the temperature range from room temperature to 400°C, while high emissivity in non-infrared atmospheric windows (ε5-8 μm=0.81) enables radiative cooling. The use of high emissivity in the non-infrared atmospheric window reduced the surface temperature of this structure by 15.3°C compared to untreated Si substrate under similar heating conditions. The temperature reduction was 34.1°C when compared to a Si substrate coated with a 200 nm Al film. This straightforward and easily scalable structure not only presents novel solutions for applications in infrared stealth and radiative cooling but also holds vast potential for diverse fields including military, aerospace, and industrial manufacturing, injecting fresh impetus and possibilities into technological advancement.

Measuring health-related quality of life in a Chinese Mainland adolescent population: psychometric properties of the Mandarin Chinese self-reported KIDSCREEN-27 and KIDSCREEN-10 index

BackgroundThe self-reported KIDSCREEN questionnaires are ideal for capturing children’s and adolescents’ health-related quality of life (HRQoL) and have gained worldwide popularity. Responding to demands for the concise nature of KIDSCREEN among Chinese Mainland researchers and practitioners, this study aimed to evaluate the psychometric properties of the Mandarin Chinese self-reported KIDSCREEN-27 (KS-27) and KIDSCREEN-10 index (KS-10), which are short versions of the self-reported KIDSCREEN-52 (KS-52).MethodsThis study reanalyzed the validation dataset of the Mandarin Chinese self-reported KS-52. The dataset originated from a cross-sectional survey conducted in Weifang City, the Chinese Mainland, from October to November 2016. Adolescents aged 11–17 years (N = 4385) were surveyed, and sub-samples (N = 841) were retested. Statistical analyses were conducted on the feasibility, item and dimension properties, reliability, and validity of the Mandarin Chinese self-reported KS-27 and KS-10.ResultsIndirect evidence from the Small Group Pilot Survey indicated that the Mandarin Chinese self-reported KS-27 and KS-10 can be completed on average in less than 12.33 mins. Their response rate exceeded 90% regardless of the unit- and item (dimension)-level. The psychometric properties of items and dimensions were likewise found to be satisfactory. Internal consistency was robust with inter-item and item-total correlations (0.173–0.873, 0.422–0.786), Cronbach’s alpha (0.786–0.881), Guttman’s lambda-2 and - 6 (0.807–0.889, 0.829–0.896), and McDonald’s omega (0.725–0.886). Test–retest reliability at both item- and dimension-level was excellent, with intraclass correlation coefficients (ICCs) of (0.590–0.696, 0.785–0.842); standard error of measurements (SEMs) of (0.352–0.635, 0.949–1.949). Confirmatory factor analysis (CFA) confirmed their five- and one-dimensional structures, albeit with slight modifications. Moreover, the multi-group confirmatory factor analysis (MG-CFA) substantiated their configural and metric invariance across gender and grade groups. Convergent validity was robust, with stronger correlations observed with comparable dimensions of the Mandarin Chinese self-reported PedsQL™ 4.0, while discriminant validity was evident with low correlations observed with less comparable dimensions. The known-group validity was mainly supported by medium to large effect sizes concerning differences in socioeconomic status (η2 = 0.07–0.17, Cohen’s d = 0.55–1.03) and mental health status (η2 = 0.09–0.40, Cohen’s d = 0.73–1.83). The Mandarin Chinese self-reported KS-52 served as the criterion; the ICCs between the Mandarin Chinese self-reported KS-27 and KS-10 and their comparable dimensions were stronger, indicating robust criterion validity.ConclusionsThe Mandarin Chinese self-reported KS-27 and KS-10 demonstrated excellent psychometric properties, indicating their good potential for measuring HRQoL for children and adolescents in the Chinese Mainland.

Warm-White Light Emission of Lead-free CsAg2I3 Single Crystal Scintillator with a One-Dimensional Electronic Structure.

Presently, the exploration of novel inorganic lead-free perovskite scintillators has emerged as a prominent topic in the field of perovskite materials. Extensive attention has been garnered by materials such as Cs3Cu2I5 due to their notable advantage in scintillation intensity, but the response time constants in the microsecond or even millisecond range severely constrain their potential applications in scintillators. In this study, large-sized (5-6 mm) CsAg2I3 single crystals with an ultrafast warm-white light emission on a nanosecond time scale are presented. Specifically, upon X-ray excitation, the single crystal demonstrates a broad-spectrum white light emission with a color temperature as high as 5129 K, attributed to its self-trapped exciton emission. The 137Cs energy spectrum reveals that CsAg2I3 possesses an ultrafast response for γ rays with a time constant of 15 ns, which is significantly faster than that of Cs3Cu2I5. Furthermore, time-resolved photoluminescence unveils a subnanosecond component with a response time of 0.9 ns. The characteristics of ultrafast warm-white light emission exhibit the significant potential of CsAg2I3 in radiation scintillation detection and its probability of playing a pivotal role in future radiation detection technology.

Peripheral Fusion of Carbon-Based Aromatic Rings to B4N4-Heteropentalene Leading to Close π-Stacking in the Solid State.

π-Electronic molecules with a BN-heterocyclic and carbon-based aromatic hybrid ring system (h-CBN) are interesting in that they potentially exhibit synergistic properties arising from the two different π-systems. Here we report the synthesis and properties of a h-CBN-type molecule (1) having a bicyclic B4N4-heteropentalene core fused with extended aromatic rings. This molecule exhibits excellent chemical stability despite the absence of bulky substituents for kinetic protection, which in turn provides effective stacking of the π-system upon crystallization. Depending on the crystallization solvent, 1 forms two polymorphs, i. e., the α- and β-phases. While both phases have one-dimensional columnar structures, the π-stacking geometries associated with the transfer integrals of the frontier orbitals are different, resulting in a twofold difference in the electrical conducting properties. We also found that upon thermal vacuum deposition, 1 gives an amorphous film, which serves as a host material for a red phosphorescent OLED device (maximum external quantum efficiency: 15.5 and 13.3 % at 0.1 and 2.5 mA, respectively).

One-Dimensional Flexible Capacitive Sensor with Large Strain and High Stability for Human Motion Monitoring.

Flexible capacitive sensors have attracted the attention of researchers owing to their simple structure, ease of realization, and wearability. Currently, flexible capacitive sensors mainly have three-dimensional and two-dimensional structures, which are subject to several limitations in their applications. A low-cost, high-efficiency, and continuously processable process was used to wrap nylon DTY (PA) filaments on the surface of silver-coated nylon (SCN) core yarns and impregnate them with waterborne polyurethane (WPU) to obtain SCN/PA/WPU composite yarns, which were then utilized in the design of SCN/PA/WPU for the preparation of one-dimensionally structured flexible capacitive sensors. The morphology and mechanical properties of the SCN core yarn, SCN/PA wrapped yarn, and SCN/PA/WPU composite yarn were characterized. The strain-sensing performance of the sensor was analyzed, and the sensor was used to monitor human physiological activities. The sensor exhibited excellent strain capacitance sensing performance with a strain range of up to 140%. With a gauge factor of 0.66 at 10% tensile strain, it can detect strains as low as 1% and has good repeatability, withstanding more than 3200 tensile-unload cycles at 80% strain. The one-dimensional structure sensor can be used to monitor the large-scale movements of joints and muscles in various parts of the human body and the physiological signals of tiny human movements, such as breathing, coughing, and facial expressions, which have potential applications in the fields of sports monitoring and smart wearable.

Spectro-spatial analysis of van der Pol-type phononic crystals

Abstract The application of phononic chains as metamaterials demonstrates their remarkable capability to manipulate the propagation of waves. These periodic structures yield frequency-dependent behavior of material comprising characteristics with many possible engineering applications. In this paper, we investigate the weak and general nonlinear behaviors of the van der Pol-type damped phononic chains. The analysis of wave propagation is initially conducted for a one-dimensional structure, and subsequently, is extended to consider the wave motion through two-dimensional and three-dimensional lattices. Results are obtained using the method of multiple scales and a Spectro-spatial analysis by employing the numerical method of the 4th-order Runge–Kutta. A new phase-diagram relation within the chain’s unit cell is also introduced aiming to enhance the numerical findings. Our results indicate that in the weakly nonlinear regime, the van der Pol-type damping closely follows the linear dispersion curve, regardless of the initial amplitude. This suggests a symmetry between energy pumping and dissipation modes, where hardening and softening behaviors align with linear characteristics of common damping mechanisms, such as viscous damping. Additionally, the formulation demonstrates the existence of limit-cycle stability in the motion of each mass. For the general damped system, it is observed that a special frequency exists where the system converges, for all wave numbers similar to the synchronization effect. Hence, the motion and the frequency of all masses are synced. Additionally, non-reciprocal wave propagation is observed, resulting in a bandgap structure with a symmetry breaking occurring near the limit cycle. These results are promising in the fields of wave emitters, wave filters, and signal encryption.

CFD-14: detecting literacy and dyslexia risks in early and primary education

This study validates the CFD-14 questionnaire, designed for families to detect early risk of literacy difficulties and dyslexia in compulsory schooling. The sample included families of 1385 students from preschool (5 years old) and 1st to 6th grade of primary education, with a median age of 9 years and two months. The CFD-14 comprises 14 items reflecting common dyslexia indicators. Its one-dimensional factorial structure was confirmed, demonstrating reliability and criterion validity through five evidences: correlation of questionnaire scores with teacher and family assessments, comparison of CFD-14 scores between a dyslexic group (n = 13) and the general sample, analysis between families with and without a history of difficulties, and comparison between groups with persistent spelling errors and those without. A direct score at the 90th percentile was identified as the objective criterion to pinpoint students at risk of literacy difficulties.

Synthesis and Characterization of Low-Dimensional Quaternary Sulfides of Thallium, Tl2Cu2GeS4, Tl2Ag2GeS4, and Tl2Ag2SnS4.

Three new low-dimensional quaternary sulfides, namely, Tl2Cu2GeS4(1), Tl2Ag2GeS4(2), and Tl2Ag2SnS4(3) were synthesized by solid-state reactions and characterized by single-crystal X-ray diffraction, spectroscopic, thermal, and photocatalytic studies. The compounds 1, 2, and 3, respectively, have centrosymmetric layered, noncentrosymmetric layered, and noncentrosymmetric one-dimensional structures, in which Cu+, Ge4+, and Sn4+ ions have tetrahedral coordination and Ag+ ion has linear, trigonal planar and tetrahedral coordinations. The monovalent thallium cations have TlS8 dodecahedral coordination and TlS7 and TlS6 coordination polyhedra of irregular shape. The compounds 1, 2, and 3 are semiconductors with the respective energy band gap values of 1.68, 2.02, and 1.90 eV. Compared to compounds 1 and 2, compound 3 has a higher efficiency value of 22.9% for the photodegradation of aqueous solution of methylene blue. Band structures and projected density of states of all three compounds were computed using density functional theory, and these results are in good agreement with experiments.

Temperature-Dependent Supramolecular Isomeric Co-CPs for Luminescence Recognition and Catalytic Oxidation.

Two Co-based supramolecular isomers were synthesized from a fluorinated carboxylic acid ligand under hydrothermal conditions at varying temperatures. Both exhibited similar one-dimensional chain structures while different bending connections of the aromatic rings led to different supramolecular structures, namely CoCP-1 and CoCP-2, respectively. The structural differences of two isomers resulted in discrepant performance with regards to luminescence sensing and catalysis. CoCP-1 demonstrated more significant luminescence quenching activity toward biomarkers 2,6-dipyridinoic acid (DPA) and high vanilloid acid (HVA), which could be distinguished in the presence of Eu3+. The limit of detection (LOD) was found to be as low as 3.4 and 1.3 μM, respectively. The recovery rate of for HVA and DPA was within the range of 89.6-101.2% and 99.7-117.9% in simulated urine and serum, respectively, indicating potential reliability in monitoring these two analytes in real samples. Notably, CoCP-2 exhibited catalytic activity for the oxidation of thioethers to sulfoxides. Our finding here suggests that the coordination conformation of the ligands within supramolecular isomers plays a pivotal role in determining the structure and luminescence sensing/catalysis performance.

Synthesis of two Cd (II)-MOFs and fluorescence sensing of 2, 4, 6-trinitrophenol and anions

Two new Cd (II) metal-organic frameworks (MOFs), {[Cd (L)0.5]·1.2DMF·H2O} n (1) and [Cd(H2L) (1, 2-die)2] n (2) [H4L = [1, 1′:4′, 1′'-terphenyl]-2, 2′', 4, 4′'-tetracarboxylic acid, 1,2-die = 1,2-di(pyridin-4-yl) ethane], have been synthesized under hydro(solvo)thermal conditions and structurally characterized by X-ray single crystal diffraction. 1 is a three-dimensional framework (3D) formed by the connections between layers, whereas 2 is a one-dimensional (1D) chain structure. Fluorescence sensing experiments show that both 1 and 2 can detect 2, 4, 6-trinitrophenol (TNP) and 2 has a lower detection limit. The detection limits of 1 and 2 were 0.18 μmol·L-1 and 0.054 μmol·L-1, respectively. However, their detection of anions is different, 1 can selectively detect MnO4-, and the detection limit is 0.38 μmol·L-1. 2 can selectively detect CrO42-, and the detection limit is 0.84 μmol·L-1. This indicates that different nitrogen-containing ligands have significant effects on the structure and properties of MOFs. In addition, 2 was used for the detection of sulfasalazine (SECT) in aqueous solution, and the detection limit is 0.29 μmol·L-1. Finally, the mechanism of fluorescence quenching was thoroughly investigated.

Polyoxometalate-derived anti-aggregation MoC nanoparticles for efficient hydrogen evolution in basic and acidic media

As a cost-effective alternative to Pt-based catalysts, molybdenum carbide (MoC) exhibits considerable potential for catalysing hydrogen evolution reaction (HER) in both alkaline water electrolyzers and proton exchange membrane water electrolyzers. However, achieving ampere-level current densities at low overpotentials remains challenging for MoC-based electrocatalysts. In this study, we utilized electrospinning technology followed by a subsequent heat treatment to successfully synthesize monodisperse MoC nanoparticles (approximately 4.3 nm) embedded in carbon nanofibers. The resultant self-supporting one-dimensional molybdenum carbide@nitrogen-doped carbon nanofiber (MoC-A@NCNF), prepared with polyoxometalate anion (POM) and polyvinylpyrrolidone (PVP), exhibits excellent anti-aggregation behavior. Benefiting from its high specific surface area and one-dimensional conductive network structure, the MoC-A@NCNF displays outstanding hydrogen evolution reaction (HER) performance in both 1 M KOH and 0.5 M H2SO4, achieving overpotentials of 491 mV and 568 mV at a current density of 1 A cm−2, respectively. Furthermore, it exhibits exceptional electrochemical stability during prolonged HER testing under both acidic and alkaline conditions.

Solvothermal synthesis, photoelectricity and photocatalysis of biselenide-containing selenidostannate hybrid with one-dimensional structure

A biselenide-containing selenidostannate hybrid with narrow band gap, [Ni(terpy)2]2[Sn3Se7][Sn3Se6(Se2)]·4H2O (1) (terpy = 2,2′:6′,2′’-terpyridine), was prepared using a Ni(II)-terpy complex cation as the template under solvothermal conditions. In 1, two SnSe5 PBUs and one SnSe4 PBU are joined through edge-sharing to form a Sn3Se9 SBU. The Sn3Se9 SBUs are connected into a 1-D [Sn3Se7]n2n− chain by sharing two Se atoms, while the Sn3Se7(Se2)2 SBUs are interlinked via the same conncetion mode to form a [Sn3Se6(Se2)]n2n− polyselenide chains containing biselenide ligands. Compound 1 exhibited sensitive photocurrent responses under Xe light irradiation, and had a steady current density of 6.88 μA·cm−2 under visible light irradiation at power of 150 W. Compound was photocatalytically active in the degradation of the organic dye crystal violet (CV) in aqueous solution at room temperature, and the degradation ratio of CV reached 93.8 % after 60 min of light irradiation. Radical quenching experiments showed that all the ∙O2− and ·OH radicals, and the photogenerated positive holes h+ were involved in the photodegradation of CV.

Two mercury(II) halide coordination polymers with efficient photoluminescence

Two coordination polymers (CPs), [Hg(Bpbp)X2]n (X = Br (1), I (2), Bpbp = 4,4′-bis(4-pyridyl)-biphenyl), were synthesized via solvothermal synthesis methods, and were further fully characterized by single crystal X-ray diffraction, powder X-ray diffraction, elemental analyses, FT-IR spectroscopy, and thermogravimetric analyses. The two CPs exhibit similar one-dimensional zigzag chain structures constructed by Bpbp ligand connecting Hg(II) cations with halide ions as terminal ligands, while the zigzag chains show different configurations, symmetries and packing modes. The results of photoluminescence experiments and DFT calculations indicate that both the halide anions and conjugated Bpbp ligands show important roles in the emission process of CPs, and halide anions may tune the luminescence properties of CPs.

Highly sensitive one-dimensional Dielectric-Superconductor photonic crystal structure for low temperature sensing applications

The work proposed in this paper investigates the design and simulation of low temperature refractive-index (RI) sensor using one-dimensional photonic crystal (1D-PhC) structure. The bilayer stack is created using dielectric and superconductor materials. The dielectric material is assumed to be air and the superconductor considered is YaBa2Cu3O7. Compared to superconductor material, air’s RI is hardly affected by the temperature. The parameter perceived by the suggested sensor for precise temperature measurement in the region of 10 K to 90 K is thought to be the superconductor’s RI, which is a function of temperature. To the best of our knowledge, the structural characteristics have been precisely adjusted to increase sensor efficiency to a level never before seen in published research. According to the findings, the temperature sensitivity of 1.524 nm/K and the maximum RI sensitivity of 1079.42 nm/RIU are found in the proposed structure. Applications for bio-sensing are a good fit for the suggested sensing device.
