Summary: Integrative neural interfaces combining neurophysiology, optogenetics, and neural imaging offer opportunities for studying neural circuits in the brain. The development of ultra-flexible, highly conductive and fully transparent microscale electrocorticogram (mu ECoG) electrode arrays with PEDOT:PSS-ITO-Ag-ITO assembly shows enhanced mechanical flexibility, robustness, and resilience to photon-induced artifacts. In vivo experiments demonstrate successful recording of light-evoked ECoG oscillations from the primary visual cortex (V1) of an anesthetized rat.

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: The paper investigates the influence of the thickness of the ITO and In2O3 layers deposited by magnetron sputtering on their physical properties. Characterization parameters were determined using AFM, XPS, and Kelvin probe. Increasing the layer thickness resulted in increased surface roughness and work function, accompanied by a decrease in the concentration of elements and compounds in the near-surface region.

Summary: The argon atmospheric pressure plasma treatment is used in combination with the conventional sol-gel dip-coating process to improve the electrical properties of ITO glass by increasing the thickness and reducing the sheet resistance of the ITO thin films. However, prolonging the plasma treatment time beyond 240 seconds can lead to an increase in sheet resistance due to the diffusion of oxygen into the bulk, reducing the level of oxygen vacancies.

Summary: In this study, wavelength-thick indium tin oxide (ITO) films were successfully grown and characterized using high power impulse magnetron sputtering (HiPIMS) with post deposition processing. The films achieved an epsilon near zero (ENZ) property at 1550 nm telecom wavelengths. By consecutively annealing the ITO film, the plasma frequency gradually shifted, enabling fine tuning of the ENZ wavelength regime from 1800 to 1500 nm. The films were characterized using spectroscopic ellipsometry, transmission electron microscopy, x-ray diffraction, and energy dispersive x-ray spectroscopy. The findings of this study provide a method to control the ENZ property at the desired wavelength and reduce absorption loss for device applications.

Summary: The prevalence of photosynthesis and its potential as a renewable energy source has led to the development of solid-state semiconductive devices like photovoltaic solar cells. However, direct utilization of plant-based biophotovoltaics (BPV) has been impracticable. In recent years, fuel cells (FCs) relying on redox potentials of algae suspensions or biofilms have shown promise as clean power generators. These algal BPVs offer advantages such as carbon sequestration and biomass harvesting. Development of high-performance BPVs is reliant on upgraded anode materials with dynamically nanostructured surfaces, but challenges in optimizing these materials hinder commercial viability. Graphene-based carbonaceous materials have been explored for FCs due to their flexible surface functionalization properties, but disorders on the molecular scale restrict efficient charge coupling. Langmuir-Blodgett (LB) film has shown potential in addressing these limitations, but its application in BPVs remains untapped. A comprehensive understanding of LB film fabrication and electron transfer mechanisms is crucial for the scalability of BPVs.

Summary: The global community is addressing the serious consequences of excessive fossil fuel use by utilizing renewable and non-renewable energy sources together. Biomass feedstocks, including microalgae, are being recognized as important energy providers to meet the needs of a growing economy and society. Algae are efficient at photosynthesis, can grow on various substrates, and are tolerant to extreme conditions. Integrating microalgae into photovoltaic platforms is an innovative technique for low-power energy supply. Our algal biophotovoltaic (BPV) platforms have been improved to produce bioelectricity, treat wastewater, and absorb CO2. This study demonstrates the sustained power output and performance of our BPV platforms after nutrient replenishment, showing their potential as long-term low-power generators.

Summary: Conventional three-electrode systems used in electrochemical measurement require time-consuming and maintenance intensive procedures. In this study, a miniaturized printed circuit board (PCB) with the same metal (gold) for all three electrodes was used to simplify the design. The novel PCB-based same-metal three-electrode system showed comparable cyclic voltammetric profiles to conventional systems, but required fewer activation cycles and exhibited higher redox sensitivity and detection window.
