Summary: The stereoassembly of 3D porous Pt-on-Pd bimetallic nanodendrites on a 2D ultrathin Ti3C2Tx MXene matrix results in a Pt-on-Pd/Ti3C2Tx catalyst with superior electrocatalytic properties towards methanol oxidation, attributed to numerous accessible electrocatalytically active sites and optimized electronic structures. Density functional theory calculations reveal significant down shift of d-band centers and weaker CO adsorption ability for the Pt-on-Pd/Ti3C2Tx model, leading to stronger poisoning tolerance and enhanced methanol oxidation activity.

Summary: This study investigated the flow and spray fields in a realistic concentric staged high-temperature-rise combustor using high-speed particle image velocimetry (PIV) and planar laser-induced fluorescence (PLIF). The results showed strong coupling between the pilot and main swirling flows, leading to the formation of recirculation zones. The presence of a precessing vortex core was observed when the two stages were flowing jointly. Comparing the flow field with the spray field revealed the importance of the unsteady flow motion in understanding the spray distribution. The findings provide valuable insights into the complex flow-spray coupling in the combustor.

Summary: A novel heterojunction composite BiPt/KTa0.5Nb0.5O3 (KTN) with optimized Bi and Pt contents was synthesized and showed improved photocatalytic performance in ammonia synthesis compared to pure KTN, 1 %Bi/KTN, and 0.25 %Pt/KTN. The BiPt alloy nanoparticles formed on the surface of KTN nanocubes provided an appropriate Schottky barrier, efficiently capturing and separating photogenerated charge carriers. The loaded BiPt alloy also broadened the material's photoresponse to visible light through surface plasmon resonance, contributing to increased photoactivity. This study not only offered a potential photocatalyst for nitrogen fixation but also proposed new ideas for designing highly efficient catalysts through bimetal alloy modification.

Summary: This study investigated the influence of Ca2+ on HA fouling and demonstrated the potential of Ca2+ addition in mitigating fouling in the coagulation-ultrafiltration process. It was found that increasing Ca2+ concentration led to an increase in filtration flux and a reduction in hydraulic filtration resistance. The effects of Ca2+ addition varied for different resistance components, with a decrease in internal blocking and concentration polarization resistance, but an increase in membrane surface deposit resistance. The main reason for the decreased filtration resistance was the enlarged particle size caused by the Ca2+ bridging effect.

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.
