Summary: Cavity microelectrodes (CMEs) provide a valuable platform for evaluating the electrocatalytic performance of micro- and nanoparticulate materials; experiments show capacitive distortion increases with powder surface area, but faradaic response mainly occurs on the first layer of the powder load, cyclic voltammetry and square wave voltammetry (SWV) are suitable for discriminating faradaic processes at CMEs.

Summary: Surface plasmon resonance (SPR) sensing is a high-sensitivity, label-free, real-time detection technique used for studying biomolecular interactions by measuring the optical refractive index of the medium. To ensure accuracy, measurements should be conducted in a temperature-controlled environment, with the proposal of using a metallic film as a heater.

Summary: A novel approach has been developed to elaborate nanoporous polymers using nanoporous gold as a template, allowing for the replication of any polymeric material based on the solubility behavior. The resulting nanoporous polymers exhibit well-defined nanostructures with a homogeneous size distribution, showing promise for versatile polymer diversity and precise tuning of nanostructure size.

Summary: This study developed an analytical treatment for rate equations with non-unity reaction orders in electrochemical processes. By linearizing the current-potential response, reaction orders and half-wave potential values can be determined. Additional protocols of kinetic analysis are discussed based on Tafel and Koutecky-Levich-like plots.

Summary: The influence of light on the contact resistivity of the electron and hole contacts of a silicon heterojunction cell was studied using the transfer length method. Results showed that measurements are more accurate in darkness and at high injection levels. Careful attention to passivation properties is needed when fabricating TLM samples.

Summary: To reduce energy costs and environmental impact in wastewater treatment plants, treating urea at the source is advantageous. Researchers have developed FTO/Ti-Fe2O3 (nanorods) photoelectrodes decorated with Ni catalyst for urea photoelectrocatalytic oxidation under solar illumination. The catalytic activity is improved by using a Ni photoelectrodeposition method. The study demonstrated the photoelectrocatalytic removal of nitrogen from urea solutions, but higher selectivity catalysts are needed.

Summary: The impact of structural parameters on the optoelectronic properties of InGaSb/GaSb quantum well structures is investigated in this study. Numerical calculations are performed to determine the emission wavelength, optical and modal gain, optical confinement factor, and threshold current density for different well material compositions, well thickness, number of quantum wells, and temperature. The results show that InGaSb/GaSb quantum wells are suitable for mid-infrared lasers operating at 300 K, with a peak gain value of approximately 1400 cm-1 and a modal gain of 94 cm-1.

Summary: A new equivalent circuit model for GCPW-MS transitions was proposed, focusing on the impact of via-hole diameter on transition performance and bandwidth. Theoretical and experimental results showed that transitions with 900μm diameter via-holes can achieve a bandwidth of up to 100 GHz.
