In situ growth of electrocatalysts is one of the promising methods to achieve high stability for electrocatalysts, wherein simultaneous cation doping could efficiently improve the active sites towards electrochemical water splitting. Herein, trimetallic FeCoNiSe₂ nanosheets (NSs) were prepared in situ on nickel foam by a hydrothermal method for the first time. The structural and morphological investigation confirms the formation of NiSe₂ NSs over nickel foam along with simultaneous doping of Fe and Co in the crystal structure of NiSe₂. The electrocatalytic efficiency of the synthesized materials was sequentially tested for HER, OER, and overall electrochemical water splitting. The trimetallic FeCoNiSe₂ NSs demonstrated high catalytic activity towards water electrolysis with a low cell voltage of 1.7 V at 100 mA cm^–2 compared to bimetallic FeNiSe₂, CoNiSe₂, and bare NiSe₂ NSs. Further, the electrocatalyst exhibits long-term stability for 40 h in 1 M KOH at 10 and 100 mA cm^–2 at 1.57 and 1.7 V, respectively. The enhanced electrocatalytic performance of trimetallic selenide nanosheets thus obtained through simultaneous doping and in situ growth on conducting metal substrates might open similar distinct approaches for developing more competent energy conversion and storage devices.</p>","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"8 16","pages":"8424–8432 8424–8432"},"PeriodicalIF":5.3,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their strong van der Waals forces and chemical inertness pose challenges for achieving effective dispersion in organic solvents through the functionalization of BNNTs. This study presents an approach to BNNTs functionalization using a two-step plasma process involving sequential treatment with Ar followed by NH₃. In the first step, Ar ions physically collide with BNNTs and induce atomic-level defects on BNNTs. Subsequently, in the second step, these defects induce chemical reactions with radials such as NH* generated from the NH₃ plasma, leading to the formation of amine functional groups. The two-step plasma process led to minimized damage to the nanotubes and an approximately 6-fold increase in amine functional groups compared to raw BNNTs. This two-step plasma process enables the stable dispersion of BNNTs in organic solvents without the use of dispersants. As a result, the two-step plasma process provides a high-concentration and stable functionalization method for BNNTs, thus enhancing their suitability for high-performance applications in harsh conditions such as in the aerospace and defense industry.</p>","PeriodicalId":6,"journal":{"name":"ACS Applied Nano Materials","volume":"8 16","pages":"8480–8488 8480–8488"},"PeriodicalIF":5.3,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that the concentration of N-CDs/2D Ni-BDC has a notable effect on the friction coefficient and wear rate of the emulsion.

Complementary characterizations indicated that the nano morphology and crystal structure of the δ-MnO₂ had no change after being loaded on Ni foam, as well as that during the EH and CH reactions, but the release of lattice oxygen was enhanced by an electronic effect, leading to the rapid migration to the catalyst surface and an enhanced activity.

Herein, we report an organic–inorganic hybrid approach to significantly increase the PLQYs of nondoped pristine DPNCs.

The PLQYs of the prepared Cs₂NaBiCl₆, MA₂NaBiCl₆, and FA₂NaBiCl₆ are 1.9%, 6.2%, and 15.4%, respectively. The enhancement of PLQYs can be due to the lattice distortion on using the unsymmetric rod-like MA⁺ and V-like FA⁺ to replace the symmetric Cs⁺, which yields faster charge transfer, enhanced excitation, and reduced nonradiative recombination, which are combined to make the self-trapped excited state brighter with significantly enhanced PLQYs.

The studied samples have a layered morphology, with individual layers with a thickness of about 20–30 nm forming the secondary porous structure of the samples. The ability of synthetic clays to remove the antibiotic drug ciprofloxacin from aqueous solutions was studied. The samples were studied using X-ray phase analysis, scanning electron microscopy and energy-dispersive X-ray (EDX) analysis, low-temperature nitrogen adsorption method, differential thermal analysis, method of adsorption of acid–base indicators, Fourier transform infrared (FTIR)-spectroscopy, and electrokinetic (ζ) potential determination. Isotherms and kinetic curves of ciprofloxacin adsorption were plotted. Adsorption kinetic curves were processed using pseudo-first and pseudo-second-order models. Langmuir, Freundlich, and Temkin models were used to process the adsorption isotherms. A comparison of the sorption capacity of synthetic clays with raw bentonite clay and activated carbon was made. It has been shown that as the degree of isomorphic substitution increases, the sorption capacity of synthetic clays increases and can reach 298 mg/g, which is 3 times more than the sorption capacity of activated carbon. The increase in sorption capacity may be associated with an increase in the negative ζ-potential of the surface as the degree of isomorphic substitution increases. It has been established that the extraction of ciprofloxacin by synthetic clays, in addition to electrostatic interactions, is also determined by their cation exchange capacity, porous-textural characteristics, and by the presence of Brønsted acid sites on the surface.

Many investigations recently are directed towards hybrid WS₂ + dielectric metasurfaces, in which coupling between excitons in WS₂ and quasi-BIC states formed in dielectric metasurfaces are studied.

Our study finds that LC reorientations give rise to splitting of quasi-BIC states into multiple modes. It was observed that in-plane LC reorientations lead to crossing behavior between electric and toroidal dipole modes, while the magnetic dipole seems to be the dominant mode across the investigated frequency range. These results are confirmed using mode analysis, far-field, and near-field radiation patterns.
