“…The tuning of plasmon resonances has important applications in biosensor devices − and photovoltaics , because the plasmon resonance strongly depends on the cluster size, arrangement, the materials used, and their composition . Especially the use of bimetallic alloys allows for fine-tuning of the plasmon resonance, which offers new pathways in anticounterfeiting: in combination with polymer supports and templates, structural color can readily be achieved by exploiting the plasmon resonance. ,− Moreover, this enables fast electrochromic color switching of smart windows . Hence, understanding the correlation of size and composition with the plasmonic and optoelectronic behavior of polymer-supported metal cluster systems carries high potential but also is a challenge.…”

Tailoring of plasmon resonances is essential for applications in anticounterfeiting. This is readily achieved by tuning the composition of alloyed metal clusters; in the simplest case, binary alloys are used. Yet, one challenge is the correlation of cluster morphology and composition with the changing optoelectronic properties. Hitherto, the early stages of metal alloy nanocluster formation in immiscible binary systems such as silver and copper have been accessible by molecular dynamics (MD) simulations and transmission electron microscopy (TEM). Here, we investigate in real time the formation of supported silver, copper, and silver–copper-alloy nanoclusters during sputter deposition on poly(methyl methacrylate) by combining in situ surface-sensitive X-ray scattering with optical spectroscopy. While following the transient growth morphologies, we quantify the early stages of phase separation at the nanoscale, follow the shifts of surface plasmon resonances, and quantify the growth kinetics of the nanogranular layers at different thresholds. We are able to extract the influence of scaling effects on the nucleation and phase selection. The internal structure of the alloy cluster shows a copper-rich core/silver-rich shell structure because the copper core yields a lower mobility and higher crystallization tendency than the silver fraction. We compare our results to MD simulation and TEM data. This demonstrates a route to tailor accurately the plasmon resonances of nanosized, polymer-supported clusters which is a crucial prerequisite for anticounterfeiting.

“…The TF-SiO x 60/PPFC developed in this study is one of the best of all papers reported for using Si-based anodes in terms of cycle life and capacity retention. The fabrication method using these mixed targets had the advantage of depositing various materials (Cu, [33] Ag, [34] and ZnO [35] ), suggesting that high-quality thinfilms for TF-LIBs can be deposited using materials other than SiO x . Figure 5d schematically shows the operating mechanism for the proposed TF-SiO x 60/PPFC TF-SiO x 100 thin-films based on the above results and discussions.…”

Development of miniaturized thin‐film lithium‐ion batteries (TF‐LIBs) using vacuum deposition techniques are crucial for low‐scale applications, but addressing low energy density remains a challenge. In this work, we designed structures analogous to SiOx‐based thin‐film electrodes with close resemblance to traditional LIB slurry formulations including active material, conductive agent, and binder. The thin‐film was produced using mid‐frequency (MF) sputtering with a single hybrid target consisting of SiOx nanoparticles, carbon nanotubes, and polytetrafluoroethylene (PTFE). The thin‐film SiOx/PPFC involved a combination of SiOx and conductive carbon within the plasma‐polymerized fluorocarbon (PPFC) matrix. This resulted in enhanced electronic conductivity and superior elasticity and hardness in comparison to a conventional pure SiOx‐based thin‐film. The electrochemical performance of the half‐cell consisting of thin‐film SiOx/PPFC demonstrated remarkable cycling stability, with a capacity retention of 74.8% up to the 1000th cycle at 0.5 C. In addition, a full cell using the LiNi0.6Co0.2Mn0.2O2 thin‐film as the cathode material exhibited an exceptional initial capacity of ∼120 mAh g–1 at 0.1 C and cycle performance, marked by a capacity retention of 90.8% from the first cycle to the 500th cycle at a 1 C rate. This work will be a steppingstone for the AM/CB/B composite electrodes in TF‐LIBs.This article is protected by copyright. All rights reserved

“…In the high-resolution XPS spectra for the IL-1β-templated PEBT film on the 4-AMP/PEDOT/SPCE, the strong C 1s peaks detected in the MIP film after the IL-1β extraction indicate four major components, which are attributed to different carbon atoms within the polymer matrix (Figures 3b and S13a). Specifically, as shown in Figure 2d, each component in the chemical bonding group separately reveals O=C-O (288.2 eV), O=C-N/C=N (287 eV), C-N/C-O (286.5 eV), and C-C (284.8 eV) [79,80]. In contrast, the C 1s spectra of the MIP/4-AM/PEDOT/SPCE represent similar chemical features of the individual components compared with the PEDOT/SPCE and 4-AMP/PEDOT/SPCE (Figure S13a).…”

Molecularly imprinted polymers (MIPs) have garnered significant attention as a promising material for engineering specific biological receptors with superior chemical complementarity to target molecules. In this study, we present an electrochemical biosensing platform incorporating MIP films for the selective detection of the interleukin-1β (IL-1β) biomarker, particularly suitable for mobile point-of-care testing (POCT) applications. The IL-1β-imprinted biosensors were composed of poly(eriochrome black T (EBT)), including an interlayer of poly(3,4-ethylene dioxythiophene) and a 4-aminothiophenol monolayer, which were electrochemically polymerized simultaneously with template proteins (i.e., IL-1β) on custom flexible screen-printed carbon electrodes (SPCEs). The architecture of the MIP films was designed to enhance the sensor sensitivity and signal stability. This approach involved a straightforward sequential-electropolymerization process and extraction for leaving behind cavities (i.e., rebinding sites), resulting in the efficient production of MIP-based biosensors capable of molecular recognition for selective IL-1β detection. The electrochemical behaviors were comprehensively investigated using cyclic voltammograms and electrochemical impedance spectroscopy responses to assess the imprinting effect on the MIP films formed on the SPCEs. In line with the current trend in in vitro diagnostic medical devices, our simple and effective MIP-based analytical system integrated with mobile POCT devices offers a promising route to the rapid detection of biomarkers, with particular potential for periodontitis screening.
