Nonstoichiometry-Induced Self-Activated Phosphors for Dynamic Anti-counterfeiting Applications.

Optical signals with distinctive properties, such as contactless, fast response, and high identification, are harnessed to realize advanced anti-counterfeiting. However, the simultaneous attainment of multi-color, -temporal, and -modal luminescence performance remains a compelling and imperative pursuit. In our work, a temperature/photon-responded dynamic self-activated luminescence originating from nonstoichiometric ZnGeO is developed with the modulation of intrinsic defects.

A Chinese telemedicine-dialogue dataset annotated for named entities.

Background: A large collection of dialogues between patients and doctors must be annotated for medical named entities to build intelligence for telemedicine. However, since most patients involved in telemedicine deliver related named entities in informal and long multiword expressions, it is challenging to tag their telemedicine dialogue data. This study aims to address this issue.

Current knowledge of TNF-α monoclonal antibody infliximab in treating Kawasaki disease: a comprehensive review.

Kawasaki disease (KD), an autoinflammatory disease primarily affecting young children, characterized by consisting of acute systemic vasculitis and coronary artery involvement in severe cases. Intravenous immunoglobulin gamma (IVIG) combined with aspirin therapy is the first-line regimen for the prevention of coronary aneurysms in the acute phase of KD. The etiology and pathogenesis of KD are unclear, but its incidence is increasing gradually, especially in the cases of IVIG-naïve KD and refractory KD.

The cusp catastrophe warning model for easily weathered granite considering energy accumulation and dissipation.

To solve the problem of destabilization catastrophe damage to easily weathered granite (EWG) which is easy to soften and disintegrate after absorbing water, there is an urgent need to study the destabilization catastrophe warning of EWG. The destabilization and catastrophe damage characteristics of EWG were analyzed from the perspective of energy accumulation and dissipation. First, the relevant data of EWG were obtained by uniaxial compression and acoustic emission (AE) test.

Influence of different fibers on compressive toughness and damage of early age cemented tailings backfill.

For improving the utilization rate of tailings and the safety of cemented tailings backfill (CTB) as earthwork materials, the influence of three types of fibers (e.g., glass, polyacrylonitrile and mixture fibers of both) on compressive toughness and damage of early age CTB was studied.

Carbon Nanotube-Modified Nickel Hydroxide as Cathode Materials for High-Performance Li-S Batteries.

The advantages of high energy density and low cost make lithium-sulfur batteries one of the most promising candidates for next-generation energy storage systems. However, the electrical insulativity of sulfur and the serious shuttle effect of lithium polysulfides (LiPSs) still impedes its further development. In this regard, a uniform hollow mesoporous Ni(OH)@CNT microsphere was developed to address these issues.

Synthesis of Si/FeO-Anchored rGO Frameworks as High-Performance Anodes for Li-Ion Batteries.

By virtue of the high theoretical capacity of Si, Si-related materials have been developed as promising anode candidates for high-energy-density batteries. During repeated charge/discharge cycling, however, severe volumetric variation induces the pulverization and peeling of active components, causing rapid capacity decay and even development stagnation in high-capacity batteries. In this study, the Si/FeO-anchored rGO framework was prepared by introducing ball milling into a melt spinning and dealloying process.

Porous Si/FeO Dual Network Anode for Lithium-Ion Battery Application.

Benefiting from ultra-high theoretical capacity, silicon (Si) is popular for use in energy storage fields as a Li-ion battery anode material because of its high-performance. However, a serious volume variation happens towards Si anodes in the lithiation/delithiation process, triggering the pulverization of Si and a fast decay in its capacity, which greatly limits its commercial application. In our study, a porous Si/FeO dual network anode was fabricated using the melt-spinning, ball-milling and dealloying method.

Possible deep connection between volcanic systems evidenced by sequential assimilation of geodetic data.

The existence of possible deep connections between nearby volcanoes has so far only been formulated on the basis of correlation in their eruptive activities or geochemical arguments. The use of geodetic data to monitor the deep dynamics of magmatic systems and the possible interference between them has remained limited due to the lack of techniques to follow transient processes. Here, for the first time, we use sequential data assimilation technique (Ensemble Kalman Filter) on ground displacement data to evaluate a possible interplay between the activities of Grímsvötn and Bárðarbunga volcanoes in Iceland.

Highly effective carbon sphere counter electrodes based on different substrates for dye-sensitized solar cell.

A monodisperse carbon sphere with high uniformity, high catalytic activity and conductivity are successfully synthesized. Versatile counter electrodes using this carbon sphere catalyst on different substrates of fluorine-doped tin oxide (FTO) glass, indium-doped tin oxide polyethylenena phthalate (ITO-PEN), and Ti foil are fabricated for dye-sensitized solar cell (DSC). The impacts of substrates on the catalytic activities of the carbon sphere counter electrodes have been also evaluated by electrochemical analysis technologies, such as cyclic voltammetry, electrochemical impedance spectroscopy and Tafel polarization curves.

[Preparation of chitosan/strontium-substituted hydroxyapatite films on titanium and its FTIR characteristics].

Chitosan/strontium-substituted hydroxyapatite (CHI/SrHAP) coatings were prepared on titanium substrate by electrochemical deposition technique containing Sr2+, Ca2+, PO4(3-) and Chitosan. The as-prepared coatings were examined by scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) tests. The results indicate that the CHI/SrHAP coatings take the morphology of flake-like rather than the needle-like crystal , and the composite coating becomes more compact.

Characterisation, corrosion resistance and in vitro bioactivity of manganese-doped hydroxyapatite films electrodeposited on titanium.

This work elucidated the corrosion resistance and in vitro bioactivity of electroplated manganese-doped hydroxyapatite (MnHAp) film on NaOH-treated titanium (Ti). The NaOH treatment process was performed on Ti surface to enhance the adhesion of the MnHAp coating on Ti. Scanning electron microscopy images showed that the MnHAp coating had needle-like apatite crystals, and the approximately 10 μm thick layer was denser than HAp.

[Preparation of fluoridated hydroxyapatite coatings on titanium by electrolytic deposition and its FTIR characteristics].

Fluoridated hydroxyapatite coatings (FHAP) were prepared on titanium substrate by electrochemical deposition technique containing Ca2+, PO4(3-), and F(-) ions. The deposition was all conducted at a constant current of 0.9 mA for 60 min at 60 degrees C.
