A series of D-A dyads and D-A-D triads molecular systems based on triphenylamine and 9-ethyl-carbarzole as donor (D) and BODIPY as acceptor (A) has been designed and synthesized. The optoelectronic properties including optical, electrochemical, and charge carrier mobility of these molecules have been investigated. We found that the D-A-D triads exhibited broader absorption, raising the HOMO energy levels and increase hole carrier mobilities. Analysis surface morphology revealed that BODIPY containing carbazole demonstrated smooth film and no macro phase aggregation was observed upon thermal annealing.

Dissolved oxygen is crucial for metabolism, growth, and other complex physiological and pathological processes; however, standard physiological models (such as organ-on-chip systems) often use ambient oxygen levels, which do not reflect the lower levels that are typically found . Additionally, the local generation of reactive oxygen species (ROS; a key factor in physiological systems) is often overlooked in biology-mimicking models. Here, we present a microfluidic system that integrates electrochemical dissolved oxygen sensors with lab-on-a-chip technology to monitor the physiological oxygen concentrations and generate hydrogen peroxide (HO; a specific ROS).

Novel π-expanded and N-doped fluoranthenes were synthesized and thoroughly investigated. These eight unsubstituted compounds are obtained in a multistep synthesis with CH activation as the last key reaction step. The structures vary in their position of π-expansion on the fluoranthene scaffold and the location of the pyridinic nitrogen atom.

Steroid hormones, especially progesterone (P), estradiol (E), and testosterone (T), are key bioactive regulators in various female physiological processes, including growth and development, ovulation, and the reproductive cycle, as well as metabolism and mental health. As lipophilic molecules produced in sex glands, these steroid female hormones can be transported through blood vessels into various body fluids such as saliva, sweat, and urine. However, the ultralow concentration of steroid hormones down to picomolar (pM) level necessitates great demands for ultrasensitive but low-cost analytic tools to implement accurate, point-of-care or even continuous monitoring in a user-friendly fashion.

Single nanoparticle (NP) cyclic voltarefractometry (CVR), realized as wide-field surface plasmon resonance microscopy (SPRM) in combination with potential cycling, has been proposed and applied to the in situ study of TiO NPs. Electrochemical activity of TiO is mainly observed outside the electrochemical stability window of water. Therefore, the response of individual anatase (a-TiO) and rutile (r-TiO) NPs adsorbed on a gold layer was studied in 0.

This study investigates the impact of integrating g-CN into CuCoO electrodes on electrochemical performance working as binder-free electrodes. Flower-like CuCoO nanostructures on nickel foam are decorated with few-layer g-CN using a secondary hydrothermal process. The hierarchical g-CN/CuCoO nanoflower electrode demonstrates a specific capacity of 247.
