Accurate determination of their band edge energetic positions is central to their efficacy for isoenergetic charge transfer to the electrolyte. Yet, conventional methods fail for nano-dimensional semiconductor electrodes due to full depletion and extremely small potential-independent space charge widths. In this regard, a new approach was demonstrated on thin film nano-TiO₂ electrodes where the current-potential (i-U) characteristics in high and low work function redox probes were interpreted to infer band edge positions in darkness. The methodology is now extended for nano-TiO₂ band edge interpretation to illuminated interfaces. Using compact 30 nm TiO₂ thin films of both anatase and amorphous phases, we analyze open-circuit potentials and onset potentials in darkness and illumination across varying pH conditions to infer band edge shifts. We also examine temperature rise due to solution heating under illumination from the diffusion-limited currents in the i-U characteristics. Additionally, signatures from surface states in the i-U characteristics are identified, their densities estimated, and their implications discussed.

The nucleation (BDD_NS) and growth (BDD_GS) sides of the BDD plate were systematically compared under different surface terminations. Oxidized BDD_NS (O-BDD_NS) provided three well-resolved oxidation peaks for VF, whereas hydrogen-terminated BDD_NS (H-BDD_NS) yielded a single distinct peak for DVF in 0.1 M H₂SO₄. Differential pulse voltammetric (DPV) methods were developed with limits of detection of 0.35 µM for VF (peak 1) and 0.34 µM for DVF and wide linear ranges in the low-to-high micromolar region. By exploiting the different surface-termination preferences and multi-peak behaviour of VF, simultaneous determination of VF and DVF was achieved. The methods showed good selectivity toward common interferents and were successfully applied to spiked river water and pharmaceutical capsules using the standard addition approach, giving recoveries close to 100 %. In the 3D-printed cell, BDD_GS was used for electrochemical advanced oxidation, achieving ∼97 % degradation of 1 mM VF and DVF in 0.1 M H₂SO₄ within 20 min under galvanostatic conditions, following pseudo-first-order kinetics.

However, the presence of external stressors, including pollution and contamination, can adversely affect their physiological processes such as metabolism, growth, reproduction and cause irregular spikes in stress hormones. These conditions lead to abnormalities in hormone levels, particularly cortisol, which ultimately impair growth performances and reduce overall yield. Monitoring external stress biomarkers is therefore crucial, with cortisol being the most reliable indicator due to its central role in maintaining homeostasis and metabolic regulation. While antibody-based sensors often suffer from low stability, limited shelf life, and poor performance under harsh environment conditions, aptamer-based sensors offer a stable, modifiable, cost-effective alternative for cortisol sensing in aquaculture systems. This study proposes the development of a reagent-free electrochemical aptamer-based sensor designed to enable real-time cortisol monitoring. The sensor incorporates a cortisol-specific aptamer functionalized with amine and thiol groups and integrates a conductive hydrogel layer to serve as an antifouling material during real-sample analysis. Square wave voltammetry was employed to investigate the sensor kinetics and aptamer-cortisol interaction mechanism, achieving a linear concentration range of 0.03–300 ng/mL and a detection limit of 0.014 ng/mL. The developed sensor was validated using fish blood samples and aquaculture water samples collected from different fish species includes, pearlspot fish (<em>Etroplus suratensis</em>) and milkfish (<em>Chanos chanos</em>).

However, while direct-recycled cathodes have demonstrated performance comparable to that of pristine materials at low cycling rates, their high-rate performance remains uncertain. Morphology changes in cathode particles, a main mode of degradation, directly impact rate performance by limiting surface kinetics and solid-phase diffusion. If direct recycling processes do not sufficiently restore pristine-like morphologies, the recycled materials may retain structural defects that hinder high-rate performance. The present work uses a physics-based pseudo-2D model to simulate hybrid electrodes with pristine and artificially “aged/recycled” NMC materials to investigate potential impacts of incorporating performance-limited aged cathode materials into cells. The study highlights how differences in transport and kinetic properties can influence rate capabilities in mixed electrodes — particularly in high-loading cells in high-demand applications. However, model results also reveal a possible mitigation strategy via dual-layer electrode architectures with lower-performing materials positioned near the current collector. Simulations of 4.0 mAh cm⁻² cells cycled at 4C using a dual-layer architecture provided approximately 5%–30% more capacity in constant-current protocols compared to homogeneously blended electrode architectures with the same loadings and mixed-material compositions.
