Special Issue Information

Dear Colleagues,

There has been a steady increase in the technological and societal impact of metallic thin films on material-based design and related research. New classes of advanced materials and highly efficient devices with bioinspired architecture heavily rely on fine-tuning fabrication parameters and optimizing deposition protocols of embedded metallic thin films on rigid or flexible substrates. Many applications in key societal domains such as industry,  medicine, or the environment currently benefit from the ability to tailor surface and near-surface properties to achieve desired functionalities.

This Special Issue welcomes a wide range of contributions (original or review manuscripts) that involve the deposition, synthesis, and characterization of metallic (plasmonic and nonplasmonic) of thin films on rigid or flexible substrates and their applications in detection platforms/sensors, nanostructured/tri-dimensional devices, or advanced nanomaterials. The topics should be related (but are not limited)  to the following:

  • Fabrication of metallic thin films using modern top-down/bottom-up approaches.
  • Fabrication or synthesis and characterization of new hybrid-based metallic nanostructures with applications in nano-microelectronics/nanomedicine/micro-nanofluidics or related areas.
  • New or improved smart nanomaterials based on metallic thin films with antibacterial properties.
  • Flexible and/or transparent detection nanoplatforms with applications in environmental research.
  • Flexible sensors based on metallic thin films: from advanced fabrication methods to real-life applications
  • Design of new or improved anti-counterfeiting tags on solid or flexible substrates based on metallic thin films.
  • Porous metallic thin films: theoretical and experimental aspects.
  • Highly ordered nanostructured surfaces based on metallic thin films.
  • Electrochemical and optical sensors based on noble metallic thin films.
  • Modeling and design of plasmonic thin films.

In order to assess the longevity of foldable electronics, folding or bending tests on model systems need to be performed. However, not all bending tests are created equal in that different configurations lead to different amounts of mechanical damage and thus different electrical responses. Two 90° bending instruments were compared using two model metallic thin film systems on polyimide to establish if the two seemingly similar bending tests yield the same results. The two film systems, namely 300 nm Mo and 130 nm Al on 50 nm Mo, were magnetron-sputtered on polyimide substrates and tested in the custom-built FLEX-E-TEST and the commercially available YUASA test that is capable of in situ resistance measurements. For statistics, 10–12 samples were tested of each film system on each folding device using the same applied bending strain and number of cycles. Samples were intermittently characterized with confocal laser scanning microscopy and electrical resistance to correlate the amount of mechanical damage (crack density) with the electrical normalized resistance ratio of the damaged area. The results show that even with the same bending radius, a similar but not identical amount of mechanical damage forms for both bending devices. Additionally, the resistance as a function of cycles also differs after 10,000 cycles. A closer examination of the damage, especially in the Al/Mo film system, indicates that the speed of the bending, and if the samples experience spring back, can alter the received mechanical damage. The in situ resistance data of the YUASA test were further examined and a suggestion of standardizing how folding or bending test results are reported is provided. Full article

The development of innovative materials with improved properties is required for the field of energy storage. This article proves that it is possible to utilize bio-derived fillers to tune the performance of biodegradable polymers. For this scope, eco-composites were attained by loading several amounts of walnut leaf powder (WLP) in hydroxyethylcellulose (HEC). Basic testing was conducted to emphasize the sample’s suitability for the pursued application. The rheological behavior was altered with the addition of WLP at low shear rates, which became more pseudoplastic, resulting in composite films with higher thickness uniformity. Wettability characteristics were used to analyze the macro-level adhesion of the platinum-containing samples, and the results showed that the presence of WLP led to the augmentation of interfacial compatibilization of the composite with the metal layer. The electron microscopy and atomic force microscopy scans showed the proper distribution of the WLP in the matrix. Local adhesion data derived from DFL-height curves further showed that the inclusion of WLP improves the adhesion capabilities at the nanoscale. The dielectric spectroscopy tests proved that the used biofiller leads to an enhancement in the permittivity of the composite with respect to the neat HEC. By accounting for all results, the generated eco-composites are suggested as alternative dielectrics for usage in the energy storage domain. Full article

Manganese doped crystalline copper oxide (CuO:Mn) and undoped CuO were prepared at room temperature by the hydrothermal method. The complete physico-chemical characterization of the materials was performed using X-ray diffraction (XRD), transmission/scanning electron microscopy (TEM/SEM), and X-ray photoelectron spectroscopy (XPS). Furthermore, their analytical applicability was tested in electrochemical experiments for a dopamine assay. According to the morphological investigation, the materials had a flat structure with nearly straight edges. The XRD analysis proved the formation of the CuO phase with good crystallinity, while the Mn doping was determined by XPS to be around 1 at.%. Under optimized conditions, at pH 5.0, the CuO:Mn modified electrode (CuO:Mn/SPE) showed a high signal for dopamine oxidation, with a linear response in the 0.1–1 µM and 1–100 µM ranges and a low limit of detection of 30.3 nM. Five times higher sensitivity for manganese doped copper oxide in comparison with the undoped sample was achieved. The applicability of the developed CuO:Mn/SPE electrode was also tested in a commercially available pharmaceutical drug with good results, suggesting that the developed sensor has promising biomedical application potential.
