Given the potential attenuation of the signal from a plasmonic sensor for the detection of fluorescent molecules when an adhesion layer between the substrate and coating is employed, this study examines the impact of various factors on the adhesion strength between gold coatings and substrates comprising glass and cyclo-olefin-polymer (COP). The objective is to identify potential configurations for high adhesion strength, thereby eliminating the need for an adhesion layer in the fabrication of optical sensors with gold coatings for diagnostic applications or to utilize a minimal adhesion layer thickness. The influence of pretreatments prior to coating deposition with oxygen plasma, ultrathin adhesion layers of titanium as well as the impact of thermal shock tests with various cycles on the coating's integrity are investigated. Two methods of adhesion strength testing were applied to ultrathin coatings on glass and polymer substrates. Cross-cut and nano scratch tests were used to assess the adhesion of the ultrathin metal layers, which provided qualitative and quantitative results. The results of the two test methods on glass substrates are in good accordance, demonstrating the highest adhesion strength for gold coatings on glass with an adhesion layer, in combination with or without plasma treatment. The cross-cut testing on COP demonstrates a constant high adhesion strength when using an adhesion layer alone or without any pretreatment, while a low adhesion strength is observed in combination with plasma treatment. Following the thermal shock test, alterations in adhesion strength were observed for the remaining configurations. The rise in the coefficient of thermal expansion of COP between +30 and 85 °C in comparison to lower temperatures, as evidenced by thermomechanical analysis, may account for the disparate adhesion strengths of COP following thermal shock tests.</p>","PeriodicalId":22,"journal":{"name":"ACS Omega","volume":"10 2","pages":"2051-2060"},"PeriodicalIF":3.7,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11755149/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiments revealed that increasing the EGR rate to 20% not only reduces NOx emissions by approximately 25% but also increases smoke by around 15%, highlighting a trade-off between NOx and particulate matter control. When EGR temperature is increased from 130 to 220 °C, NOx emissions rise by about 10%, accompanied by a 12% increase in smoke emissions, indicating that elevated EGR temperatures can counteract the NOx-reducing benefits of EGR by raising the overall combustion temperature. Additionally, a higher EGR rate shifts particle size distributions, reducing nucleation mode particles by about 30% while increasing accumulation mode particles, with peak concentrations moving toward larger diameters.

It has the advantage of reducing tissue damage to the brain due to the use of carbon fiber microelectrodes as well as having a high temporal resolution (10 Hz) sufficient to monitor neurotransmitter release in vivo. During the FSCV experiment, the surface of the carbon fiber microelectrode is inevitably changed by the fouling effect. In terms of redox peak potential and sensitivity against neurotransmitters, a changed electrode surface results in a voltammogram that differs from the precalibration. However, when an electrode is implanted in the brain, the method for monitoring the electrode status change is limited. In this study, we propose employing an electrochemical impedance concept to monitor the gradual change of the electrode surface during FSCV scanning. Fourier transform electrochemical impedance spectroscopy (FTEIS) was used in combination with FSCV to detect the real-time impedance of the electrode. The relationship between impedance and electrode surface conditions was studied by immersing carbon fiber microelectrodes in bovine serum albumin solution to induce biofouling and diminish electrode sensitivity. As a result of the nonspecific adsorption of bovine serum albumin during the interleave scan of FSCV and FTEIS, both the measured dopamine response and the capacitance of the equivalent circuit model from FTEIS decreased over time. The capacitance and sensitivity of the electrode showed correlation (R² = 0.90), while the resistance of the equivalent circuit did not. In vivo measurements using the interleave scan of FSCV and FTEIS were also carried out to observe biofouling on the FSCV electrode surface and to measure dopamine sensitivity in the striatum of the rat brain for an hour. The results showed that the resistance did not significantly change, while capacitance and measured dopamine were significantly diminishing over time.

Typically, EL devices incorporating CDs feature a layered structure, where CDs function as the central emissive layer, flanked by charge transport layers and electrodes. Under an applied external bias, electrons and holes are introduced into the active CD layer, resulting in EL through radiative recombination. However, achieving EL with natural product-derived CDs has remained elusive due to challenges such as production difficulties and quenching in the solid state. In this study, we present, for the first time, the successful realization of EL from natural product-derived CDs, synthesized using Victorian lignite through a straightforward single-step pyrolysis method. The CDs demonstrated excellent dispersibility in solvents, allowing them to serve as an emissive layer in light-emitting diodes (LEDs). This was achieved by spin-coating a concentrated CD solution between the organic hole and electron transport layers on a glass substrate coated with indium tin oxide. Remarkably, the CDs retained their dispersibility and emissive efficiency both in solution (toluene) and after film formation. Moreover, the resulting LED demonstrated blue EL, characterized by a peak emission at 460 nm and a maximum luminance of 100.4 cd/m².
