The fabrication process employed combination of RF-magnetron sputter and e-beam evaporation techniques, and to optimize the electrode performance, the Ag layer thickness within the NAN structures was varied between 4 and 20 nm. The resulting configurations were evaluated through the Fraser-Cook and Haacke figures of merit (FoM). The optimized structure exhibited high optical transmittance of 75% and a low sheet resistance (RS) of ∼5 Ω/□. Compared to a commercial sample of indium tin oxide (ITO) coated polyethylene terephthalate (PET), the NAN/PET structures show higher Fraser-Cook FoM, closely aligned with the Haacke FoM, owing to their lower RS values. In addition, the flexural resistance of the electrodes was assessed by subjecting the samples to 10,000 bending cycles. Following this test, the RS value of ITO/PET increased 26.3 times to 3312.89 Ω/□, while the NAN/PET only increased 1.25 times to 7.82 Ω/□. Even the least performing NAN sample, deposited on polyethylene naphthalate (NAN/PEN), experienced a moderate increase in resistance, stabilizing at 59.93 Ω/□.

EMD is recovered with an efficiency of 96.2% from a methanesulfonic acid leached solution of spent Li-ion batteries using an iridium-tantalum-coated titanium anode. The composite-coated electrode is characterized using electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) by comparison with those of its components: the electrode with a mass loading of 10 mg.cm-2 has the highest specific capacitance (72 F g-1) and pseudocapacitive contribution (95% at 50 mV s-1) and the lowest resistance (1.85 Ω cm2). Spectroscopic studies of the composite coating are carried out using energy-dispersive X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS), while the morphological and structural analyses are performed using field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). EMD nanoparticles with ε-MnO2 and oxygen-deficient structure are homogeneously distributed in the composite at 8.4 wt% and encapsulated within the growing PPy clusters. Thus, due to the pseudocapacitive behavior, EMD recovered from batteries contributes significantly to the capacitance of the composite.

In this work, a one-step green synthesis of hybrid Nickel Oxide-Graphene oxide nanocomposites (NiO–GO NCs) utilizing an Adhatoda vasica extract was undertaken. Numerous analytical techniques, such as EDX, XPS, FESEM, HRTEM, XRD, Raman spectroscopy, FTIR, and UV–visible spectroscopy, were employed to assess the formation of NiO on GO. The study explored the light responsiveness of NiO–GO NCs by obtaining current–voltage (I–V) measurements under visible light exposure. The synthesized NiO–GO NCs exhibited remarkable and extensive sensitivity to light over a variety of wavelengths. Furthermore, responsivity and detectivity were maximum at 480 nm (9.83 mA/W, 2.53 × 109 Jones), followed by 7.54 mA/W, 1.94 × 109 Jones, and 3.98 mA/W, 1.02 × 109 Jones, at 520 and 670 nm respectively. At 480 nm, with a biasing voltage as low as 1 nV, we got a responsivity of 6.91 µA/W and a detectivity of 5.15 × 107 Jones.

However, it remains a challenge for a sensor to simultaneously detect both airflow and strain with fast response time and high sensitivity. Combining of strain sensing and airflow sensing allows for a simultaneous response to both contact and non-contact stimuli. Herein, we demonstrate for the first time a facile approach for creating flexible airflow and strain dual response sensors based on polyurethane substrate flocked with carbon fibers. The effective transduction of airflow and cyclic strain stimuli into the electrical resistance signals enables instantaneous sensing with an high sensitivity (157.5% s m− 1) and an fast response time (37 ms). Furthermore, the sensor can easily detect subtle strain (0.1%) and low velocity airflow (0.117 m s− 1) from the perceived object. With their outstanding sensing performance, these dual response sensors are more sensitive to sound waves than airflow response sensors. Particularly, they can effectively distinguish faint signals from detected objects. Taking the advantage of the sensor, precise control and monitoring in wearable device, industrial process, aerospace, medical equipment and intelligent home furnishing system are expected.","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142210155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phase purity and effect of doping on NCYFO complex oxide on structural, thermal, magnetic and dielectric properties have been determined by various characterization techniques. The FTIR data reveal that strong metal oxide linkages can be observed in the tetrahedral and octahedral sites at wavenumbers 460 to 410 cm−1 and 595 to 540 cm−1. The X-ray diffraction (XRD) studies confirmed the spinel structure. The crystallite sizes and lattice parameters were estimated to be in the range of 31 to 22 nm and 8.32 to 8.35 Å, respectively. The X-ray photoelectron spectroscopy (XPS) study confirmed that the increase in Yb concentration results in accumulation of Yb in the grain boundaries of NCYFO in the form of Yb2O3.
