Summary: Absorption of light is a major issue in integrating optical and superconducting components in circuit architectures. This study investigates reduced indium tin oxide (ITO) as a potential transparent superconductor for electronics. Superconducting wires of reduced ITO were fabricated and characterized, showing that a 10 nm thick film of this material would only absorb about 1%-20% of light between 500 and 1700 nm.

Summary: Alpha, beta, gamma, delta-Copper(II) tetraphenylporphyrinate (CuTPP) was analyzed for its spectroscopic, structural, and morphological properties in thin film composites for optoelectronic devices. The study found that the substrate interaction induced aliphatic CH2 or CH3 formation and rearranged the bending bands of the phenyl groups. UV-vis spectroscopy showed the presence of two bands at 350 and 472 nm in the films, instead of the expected intense band between 380 and 500 nm. X-ray diffraction analysis revealed the structure of the complex, and scanning electron microscopy confirmed the growth of two-dimensional square-shaped aggregates after annealing.

Summary: The two-electrode (2E) system of the interdigitated electrode array (IDA) has the potential to miniaturize multiplex immunoassay in a microfluidic chip for point-of-care testing. A permeable and robust film was generated on the indium tin oxide (ITO) IDA chip to firmly immobilize the mediator layer. This stable platform can withstand washing steps and enable sensitive electrochemical detection in the miniaturized immunoassay.

Summary: Reflective color switching coatings based on chalcogenide phase change material (PCM) are a highly promising display technology in the future. However, controlling stress and enhancing stretchability in flexible display coatings remains a challenge. This study presents crack-reduced reflective color coatings on a flexible substrate using a buckling structure to regulate the distribution of vacancies in PCM, effectively suppressing crack formation and improving the robustness of optical and electrical properties during stretching. This opens doors for phase change display applications in various flexible and wearable display fields.

Summary: In this study, printable indium tin oxide (ITO) based transistors are used to implement a highly secure DNA cryptosystem. The devices are encoded into DNA sequences in pairs and DNA operations are performed alongside the plaintext for encryption. By using small asymmetrical ring structures, the uncertainty in channel length and thickness during printing is increased to enhance the disorder of the DNA nucleotide sequence. The findings demonstrate the effectiveness and security of the DNA cryptosystem.

Summary: A novel compound containing carbazole and pyrene units was synthesized and polymerized onto an ITO electrode for selective and sensitive voltammetric determination of Quercetin. After characterization studies, electro-polymerization of Pyr-Carb onto ITO surface significantly increased the oxidation current of QCT, allowing accurate determination of QCT in real samples. The fabricated sensor showed a linear range of 2.0-500 μM and a detection limit of 0.59 μM.

Summary: Vacuum cathodic arc TiN coatings with overlaying TiO2 film were deposited on Ti6Al4V alloy surfaces polished and surface roughened by electron beam modification (EBM). EBM transformed the alloy structure and the coatings exhibited similar surface chemistry but different topographies. Despite lower nanohardness, the hybrid surface treatment improved adhesive loads, coefficient of friction, and wear-resistance. The coatings also showed good corrosion protection and enhanced cell attachment, viability, and bone mineralization activity when cultured with human osteoblast-like cells. The results suggest a synergistic effect between the sub-micron structure and composition of the coatings and the microarchitecture obtained by EBM.

Summary: The method of contact glow discharge with sacrificial silver anodes is proposed for synthesizing silver nanoparticles stabilized by PVP. The size and polydispersity of AgNPs are affected by the concentration of PVP, showing a decrease in size and a non-monotonic relationship with stabilizer concentration. The electrochemical investigations reveal that the process provides a pseudo-stationary mode for stable nucleation and growth of nearly monodisperse nanoparticles.
