The construction of ratiometric fluorescent MOF sensors with integrated self-calibration and dual-channel detection can efficiently overcome the deficiencies of single-signal sensing. In this regard, the rational design of structurally functionalized MOFs is paramount for enhancing their performance in ratiometric fluorescent sensors. Lately, the concept of MOF-on-MOF design has garnered notable interest as a potential strategy for regulating the structural parameters of MOFs by integrating two or more distinct MOF types. Great efforts have been dedicated to exploring new MOF-on-MOF hybrids and developing their applications in diverse fields. Even so, these materials are still in the stage of advancement in the sensing field. Herein, a Zr-based metal-organic framework anchored on a rare-earth metal-organic framework (UiO-66(OH) 2 @Y-TCPP) was prepared for the ratiometric fluorescence detection toward Al (III) and pH. In this probe, the UiO-66(OH) 2 featured hydroxyl active sites for Al (III), leading to a significant enhancement in fluorescence intensity upon the addition of Al (III), while the signal emitted by the red-emitting Y-TCPP, serving as the reference, remained constant. UiO-66(OH) 2 @Y-TCPP exhibited excellent selectivity for Al (III) sensing with a wider linear range of 0.1–1000 μM, and a lower detection limit of 0.06 μM. This probe has also been utilized for the quantitative determination of Al (III) in hydrotalcite chewable tablets with satisfactory results. In addition, the probe realized ratiometric pH sensing in the range of 7–13 using UiO-66(OH) 2 as an interior reference. The paper-based probe strip was developed for visual pH sensing. By installing color recognition and processing software on a smartphone, real-time and convenient pH sensing could be achieved. This is the first ratiometric fluorescent sensor for Al (III) and pH detection based on a MOF-on-MOF composite probe, which yields two different response modes. The detection results of Al (III) in hydrotalcite chewable tables and smartphone imaging for pH test paper demonstrate the practicability of the probe. This work opens up a new outlook on constructing a multi-functional application platform with substantial potential for employment in environmental and biological analysis tasks.

[Display omitted] • A dual-emission fluorescent MOF has been synthesized based on the introduction of Eu3+ ions, into aluminum metal − organic frameworks. • The dual-emission Eu/Al-MOF is used to design the sensor for the quantitative detection of histidine and water by changing the independent fluorescence signals. • The Eu/Al-MOF has been successfully applied to the detection of histidine in urine samples. • The solid-state fluorescence of Eu/Al-MOF proves instrumental in visualizing and identifying fingerprints. Ratiometric fluorescent sensors possess inherent self-calibration features that enable the mitigation of interference from factors unrelated to the analysis. This characteristic results in heightened sensitivity and more pronounced visual detection during qualitative and quantitative analytical processes. A ratiometric fluorescence probe Eu/Al-MOF has been successfully prepared via Eu3+ doped aluminum metal − organic frameworks. Upon introducing histidine, the fluorescence intensity of Eu3+ showed a noteworthy increase, whereas the intensity originating from the ligand decreased owing to enhancing energy transfer from the ligand to Eu3+ ions in the probe. Eu/Al-MOF could detect histidine over a wider linear range of 0.1–400 μM and a lower detection limit of 0.04 μM. Besides, in the presence of water in organic solvents, the excited state of Eu3+ in the probe could be coupled with the O-H oscillation of water molecules, and the excited state energy from Eu3+ would be transferred to the water molecules so that only the fluorescence intensity of Eu3+ gradually decreased. Thus, the proportional detection of trace water could be realized. In ethanol and DMF, the detection range for water was 0.1–20 % and 0.5–20 %, respectively. Moreover, it was found that Eu/Al-MOF could efficiently achieve the visualization identification of fingerprints, providing the possibilities for applying the nano-sensor as a promising multifunctional fluorescence probe.

Data classification is an important and challenging issue encountered in many practical applications. The classifier based on Evidential Reasoning Rule (ER Rule) can well handle the uncertainty in classification and obtain competitive accuracy. However, there are many parameters to be optimized, and the computation cost of the usually adopted optimization strategy is relatively high. This fact weakens the application advantage of ER Rule classifier. To address this challenge, an asynchronous optimization approach is proposed. In the original ER Rule classifier, feature referential values and evidence weights are optimized synchronously; while in the proposed method, these two types of parameters are optimized separately based on their essential impacts on the classification results. For the optimization of feature referential values, the objective function measures the quality of belief matrix, which is the critical strategy to improve the computational efficiency. Three types of feasible objective functions are constructed. After obtaining optimal referential values, evidence weights are optimized based on the actual classification effect, and the required iterations decrease. Various experiments on 14 publicly available datasets verify the computational efficiency and classification performance of the proposed method. • The low computational efficiency of ER Rule-based classifier is addressed by optimizing its parameters asynchronously. • The objective function of feature referential values optimization measures the quality of belief matrix. • The effectiveness of the proposed method is validated by theoretical analysis and various experiments.

The transmittance modulation in the near-infrared region is relatively high, and the maximum light modulation can reach to 48.3%. Cyclic voltammetry tests indicate that the as-prepared V 2 O 5 films have high cycling stability. After 1000 cycles, the V 2 O 5 films prepared at 400 ℃ still have excellent electrochromic properties. The coloration efficiency value is ca. 29.6 cm2/C at a wavelength of 890 nm and the exact coloring/bleaching times of the V 2 O 5 device are 12 s/18 s, respectively.

[Display omitted] A three-dimensional LiCl/Li-Al hybrid protective layer is constructed on the lithium metal anode surface, which can effectively facilitate homogeneous Li+ flux distribution and induce even Li nucleation, leading to excellent dendrite inhibition ability and durable interface stability. • Li metal anode surface is modified by a simple salt solution pre-treatment strategy. • A 3D LiCl/Li-Al hybrid interface layers is in-situ constructed on Li metal surface. • The hybrid layer adjusts homogenous ions environment to induce stable Li deposition. • The quasi-solid-state lithium metal batteries deliver excellent cycle stability. The quasi-solid-state metal battery stands out as a promising candidate for the advancement of scalable, safe, and high-performance battery technologies. However, a major challenge remains in the form of short circuits arising from dendrite penetration, a consequence of uneven lithium deposition at the solid electrolyte/lithium anode interface. To address this issue, an in-situ constructed three-dimensional LiCl/Li-Al hybrid protective layer was implemented to inhibit the growth of dendrites. The enhanced interfacial dynamics were meticulously elucidated through a synergistic analysis of simulation and experimental results, highlighting the facilitation of Li+ flux distribution and uniform mass transfers introduced by the lithiophilic Li-Al alloy component.

The spinel LiNi 0.5 Mn 1.5 O 4 (LNMO) material is considered as a promising cathode in high-voltage lithium-ion batteries due to its advantageous voltage and capacity. Previous results indicate that the electrodes constructed by LNMO with the same compositions while differing in the crystallite geometries always exhibit various electrochemical performances. Here, to probe the relationships between the crystalline geometry of the obtained cathodes and their electrochemical properties, we synthesized different facet-exposed LNMOs with the same compositions using a template method. We demonstrate that the crystallite geometries of the hydroxide precursors can be tuned easily via varying the synthesize parameters, while the tuned precursors can be employed as the templates during the final product preparation. LNMOs enclosed by single {111} facets (LNMO-OH) and both {110} and {100} facets (LNMO-HP) are obtained and employed to elucidate the particle geometry-dependent electrochemical properties. Despite better rate capabilities exhibited for LNMO-HP because of the higher lithium diffusion coefficients along these crystal orientations, inferior cycling performance is released compared with its LNMO-OH counterpart. These insights can provide informative guidance in particle geometry-dependent material construction, thus helpful in realizing high-performance LNMO cathode. • Different facet-exposed LNMOs with the same compositions were synthesized. • The crystallite geometries of the hydroxide precursors can be tuned easily via varying the synthesize parameters. • Facet-exposed LNMOs exhibit various electrochemical properties. • Working mechanism of different LNMOs was investigated.

A novel porous structure MnO-SiO x @C composite has been designed and prepared as an anode material for lithium-ion batteries through scalable spray pyrolysis and a subsequent annealing process. XRD, SEM, TEM, Raman, and BET measurements indicate that the MnO-SiO x @C composite displays a spherical mesoporous structure with SiO x particles, embedded in the porous MnO structure combined with carbon coated on the surfaces. The enhanced electrochemical performance can be attributed to the mutual segregation of the heterogeneous oxides of MnO and SiO x during delithiation and the buffer composition region at the origin of uniform carbon layers and abundant nanopores. In addition, the new phase Mn 2 SiO 4 , which is formed in the MnO-SiO x @C composite after 800 ºC, can act as the joint between MnO and SiO x to restrain the strain force originating from the volume change during the charge and discharge process.

[Display omitted] • A novel PDDA/GO dual-layer coating strategy to effectively improve the performance of NCM811 is proposed in this paper. • NCM811 particles can be well-encapsulated in the resultant dual-layer by a simple electrostatic adsorption method. • The PDDA/GO coating depresses the LiF component, enables a homogeneous organic-enriched CEI film with fast Li diffusion and effective corrosion protection on cathodes. • NCM811-PDDA/GO cathodes exhibit a 77% capacity retention after 500 cycles at the current density of 50 mA g−1, against 28% for pristine NCM811. Cathode-electrolyte interphases (CEIs) are determinative to the electrochemical performance of lithium-ion batteries, especially those with Ni-rich cathodes. Herein, we employed the simple electrostatic adsorption (SEA) method to generate a homogenous polydimethyldiallyl ammonium chloride/ graphene oxide (PDDA/GO) dual-layer coating on the surface of a model single-crystalline Ni-rich cathode, LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811), and thus modified the CEIs in both compositions and microstructures. The PDDA/GO coating depresses the LiF component, enables a homogeneous organic-enriched CEI film with fast Li diffusion and effective corrosion protection on cathodes. Together with the mechanical confinement on cathodes, these characters of modified CEIs benefit the electrochemical stability effectively. For instance, NCM811-PDDA/GO cathodes exhibit a 77% capacity retention after 500 cycles at the current density of 50 mA g−1, against 28% for pristine NCM811. This study provides new insights in correlating the coating and CEIs, which effectively guide the development of Ni-rich cathodes for high performance. Such a simple strategy to form a homogeneous coating can also be extended into other electrode materials easily. [ABSTRACT FROM AUTHOR]
