Herein, we report the synthesis of vanadium carbide MXene nanoparticles (V2CTx-MXene) using innovative Spark Plasma Sintering (SPS) technology followed by exfoliation steps. The V2CTx nanoparticles were incorporated with PANI (MXene-PANI) by electrochemical polymerization of aniline monomers in the presence of V2CTx nanolayers, to be used as a highly efficient material for charge storage application. PANI nanofibers form a conductive and porous architecture, which intercalates the V2CTx nanoflakes. The resulting structure increases the interlayer spacing of V2CTx sheets, which provides a larger accessible surface area, facilitates ion transport capability, and enhances the diffusion coefficient within the composite electrode. Benefiting from the strong interaction between V2CTx and PANI, high electrical conductivity, and improved surface hydrophilicity, the MXene-PANI nanocomposite presented an excellent specific capacitance of 677.21 F/g, surpassing pristine PANI with 397.71 F/g. Furthermore, the MXene-PANI exhibited remarkable capacitance retention of 91.4 % after 10,000 GCD cycles. The impressive electrochemical performance of the composite electrode can also be attributed to the pseudocapacitive performance (redox behavior) of V2CTx nanoparticles. The resulting synergy in the V2CTₓ MXene-PANI heterojunction significantly enhances the physicochemical properties of the hybrid, which, combined with its outstanding electrochemical performance, makes it a promising material for charge storage in supercapacitors and beyond.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"702 Pt 2","pages":"139031"},"PeriodicalIF":9.7,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145102507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the practical application of Bi2S3 is limited by its poor intrinsic electrical conductivity, significant volume fluctuations and sluggish reaction kinetics. The synergistic strategy of confinement engineering and heteroatom doping can effectively address these issues. Herein, a composite material of selenium-substituted Bi2S3 (BiSSe) embedded in selenium-substituted sulfurized polyacrylonitrile (SSePAN) is successfully synthesized (denoted as BiSSe-SSePAN). The incorporation of selenium significantly enhances the electrical conductivity of the material and accelerates the redox conversion of sulfur. Moreover, the confinement effect of the SSePAN matrix effectively prevents the agglomeration of BiSSe nanoparticles and mitigates volume variations. The BiSSe-SSePAN anode demonstrates outstanding sodium/potassium storage performance, achieving a high reversible capacity, superior rate capability, and prolonged cycle lifespan (e.g. 275 mAh g-1/38000 cycles/15 A g-1 in SIBs).

The effectiveness of these approaches is largely compromised by the harsh conditions, complexity, and alteration of the original structure. Therefore, developing a facile yet effective PSM for modulating COFs' properties without altering the original geometry and/or structure is a challenge. By introducing a phosphazene moiety, ca. hexachlorocyclotriphosphazene (CP), as a donor scaffold, we fabricated a CP-modified triazine-based COF (TDCP COF) with a donor-acceptor (D-A) configuration, via a facile one-step PSM method, and used it for photocatalytic conversion of O2 into H2O2. The resultant TDCP COF with D-A characteristic and substantial intramolecular dipole moment displays a facilitated exciton dissociation and charge transfer. The modified TDCP COF not only provides more favorable adsorption sites for O2 molecules, but also manipulates the O2 activation pathways through multiple mechanisms into •O2- and singlet oxygen (1O2). Benefiting from these features, the TDCP COF exhibited a three times higher H2O2 production rate compared to TD. This work sheds light on a facile yet effective PSM strategy for the development of highly efficient COFs applied for various applications, including photocatalysis, organic solar cells, drug delivery, and gas separation.","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"702 Pt 1","pages":"138859"},"PeriodicalIF":9.7,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145005715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the absence of Kana, there was no PGM signal recorded because formed nanomagnetic probe was removed by magnetic separation. Conversely, the aptamer could recognize Kana specifically and released cDNA into supernatant. After the addition of sucrose, it was hydrolyzed into glucose by invertase. Detection of Kana was indirectly achieved based on the relationship between glucose concentration and the PGM indication. Furthermore, a miniaturized portable device was constructed by integrating the components using 3D printing technology. Under optimal conditions, rapid detection of Kana within the concentration range of 1-200 nM was achieved, with a detection limit (3σ/k) of 0.28 nM.

Here, we propose a humidity sensor based on surface-functionalized tunable PC grating. The tunable PC grating consists of a 600 nm polystyrene (PS) microsphere PC and a humidity-sensitive hydrogel. As ambient humidity increases, the hydrophilic amide groups (-CONH2) inside the hydrogel interact with the hydrogen bonds between water molecules and triggers hydrogel swelling, exerts interfacial stress on the PS microsphere lattice, thus expanding the lattice spacing of the PS microspheres and causing a red shift in the reflected wavelength. Integrating the surface-functionalized tunable PC grating into a Czerny-Turner (C-T) optical system enables us to directly translate humidity into precise spectral shifts, overcoming the limitations of human eye-based observations. Experimental results demonstrate a strong linear response over the range of 24-94 % relative humidity (RH), as well as excellent repeatability and long-term stability.
