Incompatible electrode/electrolyte interface often leads to dendrite growth, parasitic reactions and corrosion, posing significant challenges the application of Zn anodes. Herein, we introduce a biomimetic antifreeze protein localized gel electrolyte (ALGE) with multifunctional capabilities address these issues by combining modification optimization. ALGE modifies Zn2+ solvation structure hydrogen‐bond network adjacent zinc anode, effectively suppressing hydrogen evolution. Additionally,...
In most of the reports, ball-milling graphitic materials would lead to decrease their crystal degree and further amorphization. However, large enhancement carbon black graphitized induced by ball milling were herein observed. The hollow structure remained without collapse. But from high resolution transmission electron microscopy, morphology each nanoparticle is changed polyhedron sphere after a certain time ball-milling. Accordingly, transformation model was proposed.
A label-free electrochemical immunosensor for cardiac troponin I was prepared by using a helical carbon nanotube-supported aldehyde-functionalized ionic liquid. Because of the good conductivity liquid and nanotubes, high sensitivity obtained. Functionalized provided binding sites antibody, which simplified process sensor construction. Cardiac detected this with linear range 0.05–30 ng/mL detection limit 0.03 ng/mL. The had satisfactory reproducibility, sensitivity, acceptable specificity.
Abstract The hybrid plasmon composition based on MoS 2 has been extensively studied as a higher disposition surface enhanced Raman scattering (SERS) substrate. In this paper, novel silver nanoparticle SERS substrate was developed via in situ microwave synthesis approach three dimensional (3D) nanoflower (MoS NF/ Ag NPs). prepared sensor strong activity malachite green (MG), the enhancement factor (EF) is high 1.46×10 12 . standard signal peak of MG at 1618 cm −1 good linear relationship 10...

Through the analysis of electron paramagnetic resonance (EPR) spectra from patients with pigment gallstones, it was found that both Fe3+ and Cu2+ signals were detected in gallstone powder, exhibiting relatively high intensity. The EPR signal for Fe(III) showed g = 4.18 ΔHpp 4.85 mT, presenting an asymmetric high-spin spectrum; Cu(II), g‖=2.36 g⊥=2.15 observed. This study explored relationship between bile pigments /Cu2+ ions, noting routine health examinations typically do not include...
This paper presents the design of a 30 kV/2.03 A high-voltage capacitor charging power supply, centered around an enhanced resonant converter, for use in high-power excimer lasers and other related pulsed applications. Typically, stray parameters high-frequency transformers negatively impact converter performance. Based on analysis series is proposed, which leverages transformer to benefit converter. Through calculations simulations, it was found that smaller (Cp) enables dual-pulse rapid...
Under microwave radiation, Ag+-doped CdS semiconductor nanocrystals with high photoluminescence quantum yield (∼58%) and a surprisingly large optical window (480 to 630 nm) are formed controllably using center-doping strategy optimized through green approach in pure water solution.
One chemical reagent, hydrazine hydrate, was discovered to accelerate the growth of semiconductor nanocrystals (cadmium telluride) instead additional energy, which applied synthesis high-quality CdTe at room temperature and ambient conditions within several hours. Under this mild condition mercapto stabilizers were not destroyed, they guaranteed nanocrystal particle sizes with narrow uniform distribution over largest possible range. The (photoluminescence emission range 530-660 nm)...
The nonspecific adsorption of proteins and bacteria on the surface polydimethylsiloxane (PDMS) had been a serious concern in wide range applications, such as medical devices. In order to improve anti-adhesive antibacterial capability, bare silver nanoparticles (AgNPs, ~15 nm) were generated in-situ their without extra reducing stabilizing agents. main reason for this was that SiO2 microspheres are covalent bonded bulked PDMS could not only generate AgNPs spontaneously but also insure no...
We demonstrate that silica microspheres can act as a sensitive fluorescent sensor and adsorbent of Ag + in aqueous media. These thiol‐functionalized are doped with quantum dots (QDs) using organosilane chemistry one‐step preparation. Ligand exchange takes place between the thiolated acid‐capped QDs, making doping easy. adsorption by causes decrease fluorescence intensity QDs. The detection limit for is found to be 10 μmol/L. abundance thiol groups on surface could effectively remove through...
Organic functional group ligands were connected to silica submicrospheres, and the antibacterial activity of AgNPs with was compared that bare AgNPs.

A green and simple approach has been developed to synthesize un-coated Ag nanoparticles (AgNPs) in situ on the surface of thiol-group-functionalized silica dioxide microspheres (TSMs) aqueous solution. As soon as Ag+ ions attach onto TSMs, nucleation growth AgNPs can spontaneously complete within one minute without other reducing agents or capping agents. The main reason is that self-assembled silane-layer formed by mercaptosilane molecules could reduce Ag0 formation energy, transport...

The coalescence and structural transformation of closed-shell graphitic carbon (CGC) induced by KOH activation were investigated scanning electron microscopy, high resolution transmission X-ray diffraction Raman spectroscopy. It was found that with graphitization at 2800 °C, CGC retains a nanosized polyhedral structure diameter ca. 25 nm. These thermally stable nanoparticles could be coalesced reconstructed to form micron-sized dish stacked when treated low temperature 400 °C. Each the...
