Herein, the hydrothermal-based synthesis of a multiphase ferromagnetic catalyst CoFeP, comprising FeP, CoP, and Fe2P is reported. Structural analyses confirm the coexistence of phases, and electrochemical studies reveal excellent OER activity. CoFeP exhibits an overpotential of 335 mV at 50 mA cm−2 and a Tafel slope of 116 mV dec−1 without a magnetic field, whereas under the magnetic field of 2000 G, these values lowered to 235 mV and 93 mV dec−1, respectively. The enhancement is attributed to magnetic-field-induced spin polarization, surface reconstruction, and increased ECSA from 70 to 110 mF cm−2, highlighting the potential of magnetic modulation for boosting catalytic performance. Through spin-polarized Density Functional Theory (DFT) simulations, the structural and electronic features of CoFeP, providing theoretical insights into its role in the Oxygen Evolution Reaction (OER) is elucidated. This investigation demonstrates that the application of an external magnetic field significantly reduces the overpotential required for OER as the adsorption of intermediate species becomes stronger due to more charge transfer, aligning with experimental observations. These findings highlight the interplay between magnetic fields and electrocatalytic performance, offering a pathway to enhance energy conversion efficiency.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 17","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500321","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the uptake mechanism of these nanostructures by cell membranes is fundamental to improving and broadening their application. In this study, the kinetics of interaction of monoolein (GMO) cubosomes or dioleoylphosphatidylethanolamine (DOPE) hexosomes with supported lipid bilayers (SLBs) with varying compositions and stiffness, as valuable model membranes, are investigated by neutron reflectivity (NR) coupled with quartz crystal microbalance with dissipation monitoring (QCM-D). Atomic force microscopy (AFM) is also used to analyze SLBs topography after such interaction. Cubosomes rapidly interact with SLBs, resulting in lipid exchange between the two systems, destabilizing the bilayer, and ultimately causing its removal. The inclusion of cholesterol (CHOL) in the SLB confers rigidity, making it more resistant to removal. Completely different results are obtained when hexosomes interact with SLBs: an intrinsic resistance of the bilayers toward these nanoparticles is observed, regardless of CHOL presence, combined with a slight change in SLB composition, suggesting that hexosomes tend to fuse with the SLB. These findings provide new and valuable insights into the potential mechanisms and kinetics of cellular uptake of these systems, enhancing their potential as drug delivery vectors.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 17","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500186","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beyond device geometry, reaching optimal operation of organic electronic circuits requires the optimization of the physico-chemical properties of the channel. Toward this end, the effects of a “bulk” doping of the channel material and its influence on the contact resistance (RC) at the interface between a Polymeric Mixed Ionic-Electronic conductors (PMIECs) and the Source (S) and Drain (D) electrodes are presented. An easy-to-implement method to achieve ultra-low contact resistances in OECTs is introduced. By incorporation of LiTFSI, a 4x transconductance improvement is achieved, and a decrease of RC by a factor of ≈2 and ≈40 has been observed for p-type or n-type PMIECs, respectively. It reaches an unprecedented width-normalized contact resistance value as low as 1 Ohm.cm with the p(g2T-T) polymer. The formation of very localized domains in the polymeric matrix in the vicinity of the electrodes, as a result of the reduction of TFSIˉ anions, which modulates the energy barrier at the S/D interface, is suggested here. Furthermore, both p(g2T-T) and p(gNDI-gT2) polymers exhibit low water uptake with minute amounts of LiTFSI. Worth noticing, doped p(g2T-T) preserves its volumetric capacitance and demonstrates an exceptional long-term stability. Finally, a universal strategy to fine-tune OECT performances, drawing prospects for implementing next-generation applications in organic bioelectronics and neuromorphics, is proposed.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 16","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500208","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144894221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extracellular vesicles (EVs), nano-sized particles present in body fluids such as exhaled breath, offer a promising diagnostic route. EVs carry molecular cargo from their parent cells, including cancer-specific protein biomarkers, making them ideal targets for early detection. This study presents an electrochemical aptasensor platform for detecting EVs associated with non-small cell lung cancer. A microfabricated gold chip functionalized with AptTex, a thiol-modified aptamer targeting the CD44 biomarker, is developed. Electrochemical impedance spectroscopy confirms aptamer immobilization, and the platform successfully detectss extracellular vesicles in vitro from non-small cell lung cancer cells with a detection limit of 3.0 × 106 particles/mL and ΔRet = 476 ± 192 Ω. Calibration plots for generic extracellular vesicles demonstrated a detection limit of 7.0 × 106 particles/mL. The platform shows sensitivity, reproducibility, and minimal sample requirements. These findings demonstrate the potential of this aptasensor for future integration into a portable disease breathalyser, enabling non-invasive early detection of lung cancer.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 17","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500176","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145028448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using both experimental techniques and atomistic simulations, the magnetic properties of Co/(Tb-Co) bilayers are studied across a broad range of parameters, including the thicknesses of the two layers and the composition of the alloy layer. This work demonstrates the ability to precisely modify the compensation point of Tb-Co alloy thin films by adding a Co underlayer with a specified thickness. Furthermore, the range of parameters are identified for which the magnetization reversal of the alloy and Co layers occurs synchronously and provides a simple expression for calculating the effective composition of the bilayer system. Additionally, it is shown that an exchange-spring magnet behavior can emerge when the alloy is Tb-dominant and the Co underlayer thickness exceeds a critical threshold. It is also demonstrated that for Tb concentrations where the alloy layer is expected to be paramagnetic, the exchange coupling with the Co layer locally induces ferrimagnetic order near the interface, leading to a second transition back to Co dominance.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 16","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500330","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144894291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
