This work is a preliminary assessment of comparative piezoelectric efficacy influenced by changes in synthesis, effecting dimension and particle size. Advantages of hydrothermal, molten salt, and solvothermal synthesis methods were leveraged to facilitate several chemical and surface engineering techniques to enhance piezoelectric properties by increasing the surface area of zinc stannate nanoparticles. The combination of these treatments reduce the size of zinc stannate to approximately ∼40nm-80nm weblike networks. Scanning electron microscopy (SEM) and X-Ray Diffraction (XRD) analysis reveal a mesoporous protonated tristannate (H₂Sn₃O₇) nanoweb template with connecting wirelike strands having diameters ranging from 12-27nm across and pores up to 50nm in diameter. Subsequent solvothermal treatment produces the perovskite nanoweb in a mixed solvent solution of critical dielectric conditions found to be 80% ethanol and 20% water for maximum Zn²⁺ deposition. ZnSnO₃ nanowebs (NW) were deposited in PDMS thin films and used as a piezoelectric nanogenerator (PENG) to characterize its electrochemical properties. Comparative voltage analysis of PDMS films made with weight percentages of (0%, 1%, 5%, 10%, 15% and 20%) zinc stannate sub-microcubes and nanowebs morphologies were done using an oscilloscope. These tests reveal an increased voltage output for the zinc stannate nanoweb morphology. The combination of these synthesis methods forming 3D zinc stannate nanoweb arrays could have far-reaching implications in producing other metal oxides when approaching the design of perovskite nanomaterials and piezoelectric energy harvesting systems in the coming decade.</div></div>","PeriodicalId":100942,"journal":{"name":"Nano Trends","volume":"11 ","pages":"Article 100120"},"PeriodicalIF":0.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144481486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbon materials serve as excellent hosts for organic guest molecules. In this study, pyrene molecules were incorporated into five different carbon matrices using a low-temperature thermal encapsulation technique, and the resulting materials were evaluated as effective electrodes for electro-osmotic pump (EOP) application. Since pristine pyrene is electrochemically inactive, it was electrochemically oxidized prior to its use in the EOP. The five carbon materials used in this study, super carbon (SC), multi-walled carbon nanotubes (MWCNTs), Ketjen black carbon (KC), activated carbon (AC) and hard carbon (HC) underwent thorough physicochemical characterization. The encapsulation of pyrene within these carbon matrices, followed by the electrochemical oxidation of the guest pyrene molecules to obtain eSCO, eCNTO, eKCO, eACO, and eHCO, was confirmed through spectroscopic and electrochemical studies. An EOP consists of a silica frit sandwiched between two flow-through electrodes. Five EOPs were assembled with eSCO, eCNTO, eKCO, eACO, and eHCO as the active electrode materials. The water pumping performance of all the EOPs was found to be linearly dependent on the applied voltage. The electro-osmotic flux of the EOPs with eSCO, eCNTO, eKCO, eACO, and eHCO was measured at 33.81, 31.48, 31.18, 20.68, and 7.95 mL min⁻¹ V⁻¹ cm⁻², respectively.
