Tip-Enhanced Raman Spectroscopy (TERS) offers an excellent solution to this demand. In addition to providing chemical composition through the Raman spectrometer, TERS leverages the high lateral resolution of the coupled Atomic Force Microscope, enabling chemical and morphological characterization of samples down to the nanometer scale. This study advances the application of TERS by employing ad-hoc prepared TiN-coated probes, engineered to operate in cleanrooms while guaranteeing remarkable performances in terms of electromagnetic field enhancement. The subject of this analysis is a strained-silicon-based device, a technology meant to enhance the carrier's mobility in Complementary Metal-Oxide-Semiconductor (CMOS) architectures. The goal of the characterization is to detect the strain induced by a thin Si1-xGex alloy grown on a Si(100) substrate in the silicon lattice. TERS enables not only the detection of strain in the crystal structure but also its magnitude at different levels of depth, despite the penetration depth of the laser employed.

Organic semiconductors are particularly appealing for these applications due to their optoelectronic properties and biocompatibility. This study examines the material properties necessary to localize the optical excitation and achieve optoelectronic transduction with high spatial resolution. Using photovoltage and photocurrent microscopy, we investigate spatial broadening of local optical excitation in Phthalocyanine/3,4,9,10-Perylenetetracarboxylic diimide (H2PC/PTCDI) planar heterojunctions. Our measurements reveal that resolution losses are tied to the effective diffusion length of charge carriers at the heterojunction. For the H2PC/PTCDI heterojunction, the diffusion length is determined to be λd = 1.5 ± 0.1 µm, attributed to reduced carrier mobility. Covering the heterojunction with poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) improves the charge generation performance but increases the carrier diffusion length to λd = 7.0 ± 0.3 µm due to longer lifetime and higher carrier mobility. These findings elucidate the physical mechanisms underlying transduction and provide design principles for organic semiconductor devices aimed at achieving high efficiency and high spatial resolution for wireless and optically activated bioelectronics.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 9","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400822","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914112","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}

Motivation is the evaporation-driven deposition of material during the fabrication of organic thin film electronics. A transition in the phase-separation morphology from an array of droplet-shaped domains deposited periodically parallel to the slot opening to isotropically dispersed solute-rich droplets with increasing coating velocity is found. This transition originates from the competition between the injection of the solution into the film and diffusive transport that cannot keep up with replenishing the depletion of solute near the domains. The critical velocity of the transition is determined by the ratio of two length scales: i) the spinodal length, which implicitly depends on the evaporation rate and the properties of the solution, and ii) a depletion length proportional to the ratio of the diffusivity of the solute and the coating velocity. For coating below the critical velocity, the domain size and deposition wavelength are proportional to a solute depletion length. This competition in the mass transport is inherent in any kind of unidirectional deposition of demixing solutions and the findings should therefore apply to many coating techniques and forced demixing processes.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 5","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400556","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497157","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}

Pd/Co/Pd multilayers hosting perpendicular magnetic anisotropy and interfacial Dzyaloshinskii-Moriya interaction are prototypes for high density magnetic memory devices. This work presents the creep regime DW dynamics in Pd/Co/Pd trilayers with Ta buffer layer excited by symmetric field-induced domain wall motion using Kerr microscopy. A systematic increment of DW velocity with increasing Co thickness is observed. SQUID-VSM measurements reveal that the effective anisotropy constant decreases with the Co layer, leading to an increased DW width. Kerr microscopy images confirm that the DW is becoming rougher with magnetic layer thickness because of the dominance of magnetostatic energy over the DW energy. Hard X-ray photoemission spectroscopy (HAXPES) reveals the presence of alloying at interfaces of Co/Pd. The asymmetry in magnetic circular dichroism HAXPES at the Pd 3d edge pictures the induced magnetic moment in Pd which is consistent with the larger saturation magnetization obtained from vibrating sample magnetometry. Extended X-ray absorption fine structure performed in out-of-plane and in-plane geometry shows the disordered nature of the Co local environment with the interdiffusion of Pd atoms into Co causing an asymmetry in the bonds.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 9","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400804","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914473","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}

To address this sustainability challenge, freshness identification in food packaging using intelligent materials has gained traction. This work introduces a chitosan-graft-gelatin (CS-g-GEL) hydrogel, incorporating a pH-responsive dye, bromothymol blue (BTB), as a colorimetric freshness indicator to monitor the spoilage of chicken breasts. The successful formulation of the hydrogels is verified using FTIR, AFM, SEM, TGA, and 1HNMR characterization techniques. At pH 5 and pH 7.4, the swelling capacity of the hydrogel is 790% and 470%, respectively. A rise in colony-forming units (CFU) from 5.5 on day 1–7.4 log CFU g−1 on day 7 indicate microbial activity, and the production of carbon dioxide due to deteriorating food freshness decreases the pH in the food package. Additionally, CO2 concentrations rise from 3.2 on day 1–22.1 (% v/v) on day 7, while O2 levels decreases from 23.8 to near 0.5 (% v/v) in the same period. The developed hydrogel is demonstrated to serve as a smart and visual indicator of food freshness and offers a new dimension in the use of intelligent materials toward a global challenge.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 9","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400799","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143914003","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}

These drops, despite being in a metastable state, can remain liquid for extended periods if temperatures are above the homogeneous nucleation point. Impact of such liquid drops with a cold solid surface is one of the reasons for ice accretion, which in many cases can represent a safety hazard. The study of supercooled drop impact dynamics is key to developing materials that provide resistance against the formation and accumulation of ice. In this work, the impact of supercooled water drops on dry icephobic coatings based on gradient polymers deposited via initiated chemical vapor deposition (iCVD) under several conditions is analyzed. Experimental results show that coated surfaces potentially decrease the freezing probability upon impact. The gradient polymer surfaces with higher roughness and lower wettability do not increase the freezing probability upon impact but result in rebound and eventual roll off the surface, indicating that surface hydrophobic properties prevailed over the impact. The findings demonstrate the remarkable efficacy of gradient polymer coatings in inhibiting drop freezing, even under high wind velocities, and provide insights for the design of durable and effective anti-icing coatings across diverse applications.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 7","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400723","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787092","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}

Employing a fast, inexpensive, and reproducible CO2 laser ablation process, polydimethylsiloxane molds are successfully created measuring 10 × 10 mm2, with arrays of conical cavities reaching depths of 1288.17 ± 128.93 µm. While this versatile fabrication technique is previously demonstrated for microneedles, it lacked a comprehensive performance evaluation of the produced needles. The study fills this gap by providing significant experimental data on the in vitro and ex vivo performance of the MilN patches. The applicability of the method is demonstrated by systematically casting and testing patches comprising various hydrophilic polymers and compounds.

Here, a method for creating dynamic surface topographies with high deformation amplitude using plasticized liquid crystal polymeric networks is proposed. Low molecular weight liquid crystal 5CB is selected as the plasticizer, which is then integrated into the liquid crystal polymer networks (LCNs) and the liquid crystal oligomer networks with longer main chains (LCONs). Upon actuation, the plasticized LCN coating reaches an amplitude of 30%, which is 14% larger than that of the pure LCN system. While the plasticized LCON coating exhibits a significant amplitude of close to 70%, over 37% greater than that of the pure LCONs. The plasticized LCONs exhibit more pronounced deformations than the plasticized LCNs due to their greater flexibility. A physical model explaining the underlying deformation mechanism is further developed.
