Summary: Microfluidic fuel cells can be used as micro-scale power sources due to their potential high energy densities. However, they often face mass transfer limitations in diffusion transport. To overcome this issue, a novel design that integrates slanted groove micro-mixers on the side walls of the channel is proposed, which enhances mass transfer and improves convective mixing. Additionally, a simplified mass transfer model and a dimensionless correlation are developed to analyze the effects of design parameters on the limiting current density.

Summary: Measurements were taken of the far-field sound from two types of three-dimensional discontinuities - swept forward-facing steps and a circular embossment - immersed in a low Mach number turbulent boundary layer. The results showed that the far-field sound from the swept forward-facing step scaled with the step-normal component of the boundary-layer edge velocity, while the far-field sound from the circular embossment was qualitatively similar to that from a forward-facing step of the same height. A prediction formula for the embossment noise was derived based on the step-normal velocity scaling and an existing prediction formula for the sound radiated by a forward-facing step, which showed good agreement with the measured sound spectra.

Summary: This study investigates the coherence of turbulent fluctuations in a turbulent vertical natural convection boundary layer immersed in a stably stratified medium. The results show that streamwise velocity fluctuations exhibit coherence over large streamwise distances, thanks to large-scale motions (LSMs) observed in the flow. The LSMs have significant meandering and contribute significantly to turbulence production in the outer layer.

Summary: Large eddy simulation is used to study the gas-particle two-phase transverse jet in supersonic flow. The Eulerian method is used to simulate the fluid, and the Lagrangian method is used to simulate the particles. Different particle mass fractions and Stokes numbers are studied numerically, with the findings that larger particles are mainly located above the counter-rotating vortex pair and smaller particles are mainly located in the counter-rotating vortex pair. Characteristic phenomena such as particle trailing and wave structure constructed of particle cloud are observed, with the particles also lowering the Mach disk.

Summary: Using high-frequency field measurements, we find that friction velocity is only predictive of sand fluxes on long timescales and under ideal surface conditions. Variability in sand flux at a given friction velocity is driven by changes in surface conditions rather than turbulence. These findings can improve sand flux models and clarify their limitations.

Summary: This work investigates the steady-state boundary layer near a rotating iron hemispherical electrode in an electrochemical cell. The dissolution of the electrode in the electrolyte results in a concentration boundary layer, which is thinner than the hydrodynamic boundary layer due to a Schmidt number Sc = 2000. The potential applied to the electrode causes an increase in fluid viscosity and a decrease in the diffusion coefficient, coupling the hydrodynamic and chemical species fields. The study obtains a steady-state solution for the governing equations in terms of a power series of the polar angle.

Summary: This work presents a method for photo-thermo catalytic hydrogen production at low temperatures using cost-effective, nonplasmonic, and metal-free nitrogen-doped carbon materials. By improving carrier generation and enhancing electron migration through photothermal conversion, the recombination of electron-hole pairs is suppressed, promoting hydrogen production by photocatalysis. Furthermore, the generated hydrogen radicals facilitate the regeneration of active sites for hydrogen production by thermocatalysis. These results demonstrate the great promise of carbon materials for photo-thermo catalytic hydrogen production at low temperatures.

Summary: A light strategy for controlling high-throughput splitting of binary droplets and transport of generated microdroplets on high-energy substrates is reported. Surface tension gradient-induced Marangoni flow and significant viscous effect at the droplet bottom are responsible for binary droplet splitting. The temperature gradients established at the core heating zone enable the transport of generated microdroplets away from the laser-acted zone. Assisted by hydrophobic stripes on high-energy substrates, high-throughput binary droplet splitting and controllable transport of generated microdroplets can be achieved.

Summary: Mesoporous TiO2 films have high potential in photocatalysis and photoelectrochemistry for energy and environment applications due to their high specific surface area and regular mesopore structure. However, the low catalyst loading caused by damage during the preparation process still limits their performance. In this study, a multi-step evaporation-induced self-assembly method is proposed to develop mesoporous TiO2 photoanodes with high catalyst loading. The resulting photoanodes have high catalyst loading without damage, large specific surface area, and retained regular mesopore structure, leading to improved mass transport. The superior performance of the mesoporous TiO2 photoanodes prepared by this method is also demonstrated in a photocatalytic fuel cell, with a significant increase in short circuit current density and maximum power density. This study provides a new approach to preparing high-performance mesoporous TiO2 films for various photocatalytic and photoelectrochemical applications.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
