Summary: This paper proposes a novel measurement method to address the self-absorption effect in X-ray absorption spectroscopy in fluorescence yield mode for surface analysis. The method, tested on copper samples, utilizes the L-line fluorescence that cascades from the KLL Auger process caused by K-shell absorption. The obtained spectrum is not distorted by the self-absorption effect and exhibits a wide energy range oscillation. The method is also applicable to samples with uneven surfaces, making it suitable for various real materials.

Summary: This study used LIE-DECT to measure the ECV in HFpEF patients and found a correlation between ECV and the risk of HFpEF, as well as cardiac structure and function. ECV was significantly higher in the non-ischaemic and ischaemic HFpEF groups compared to the control group, and a higher ECV/remote ECV was associated with both non-ischaemic and ischaemic HFpEF after adjusting for confounding factors. There was also a positive correlation between ECV and cardiac structural and functional variables. Subgroup analysis showed a positive correlation between ECV/remote ECV and ischaemic scar burden with heart failure classification in the HFpEF subgroup.

Summary: This study proposes a novel method to address the challenge of manufacturing large-size workpieces with desirable strength-plasticity synergy in Al-Zn-Mg-Cu alloys by joining extruded profiles of Al-Zn-Mg-Cu-based composite reinforced by trace in-situ TiC-TiB2 nanoparticles through friction stir welding (FSW). The nanoparticles can weaken the grain boundary segregation, avoid hot cracking, promote nucleation of precipitates, increase the proportions of low-angle and high-angle grain boundaries, and enhance the strength and plasticity of the composite. Additionally, the nanoparticles inhibit abnormal grain growth during post-weld heat treatment, strengthening the FSW-ed joint.

Summary: This study investigated the metastable pitting corrosion mechanism of laser powder bed fusion (LPBF) produced Ti-6Al-4V. The passive films of samples were produced by potentiostatic polarization in NaCl solutions with different concentrations, and electrochemical measurements were employed to understand the influence of Cl- on the characteristics of passive films. The frequency of pitting nucleation and the pit dimension increase with increased Cl- concentration. The attack of Cl- promotes the dissolution of passive films, resulting in the formation of pitting corrosion due to the condensation of voids caused by the ingress of Cl-.

Summary: This study investigates the corrosion behavior and mechanism of laser powder bed fusion produced (LPBFed) Ti5Cu and its heat-treated counterparts in 3.5 wt% NaCl solution. Heat treatment enhances corrosion resistance by generating Ti2Cu phase and forming a stable oxide film. The Ti2Cu phase acts as a microanode, decelerating corrosion on the α-Ti phase. The as-LPBFed Ti5Cu exhibits the worst corrosion resistance due to increased electron diffusion rate and preferential corrosion of the thermodynamically unstable α'-Ti phase in the acidic environment.

Summary: The corrosion behavior and mechanism of laser powder bed fusion (L-PBF) produced CoCrW were studied in a 0.9 wt% NaCl solution with a pH of 2. It was found that the corrosion resistance of the alloy increased after 28 days of immersion due to the formation of an oxide film, resulting in an increased corrosion potential and a decreased passivation current density. The corrosion mechanism of L-PBF-produced CoCrW could be explained by the formation and dissolution of the oxide film, leading to the shrinkage of the melt pools formed during the laser melting process.

Summary: Due to their high mechanical properties, good corrosion resistance, and excellent biocompatibility, beta-type Ti alloys are widely used as biomedical implants. Rapidly developed powder bed fusion (PBF) technologies have become new methods for fabricating these alloys. This review article summarizes recent advances and perspectives on various aspects of PBF-produced beta-type Ti alloys, including feedstock powder characteristics, microstructure, mechanical properties, and corrosion behavior. The results show that PBF-produced bulk beta-type Ti alloys exhibit higher strength and slightly reduced deformation strain compared to conventional counterparts. The corrosion behavior of these alloys depends on their phase constituents in the microstructure, which are influenced by the fabrication methods. PBF-produced lattice structures of beta-type Ti alloys with lower and controllable moduli are also developed for biomedical implant applications. However, research on PBF-produced beta-type Ti alloys for biomedical implants is still in the initial stage.

Summary: Membrane separation and sulfate radicals-based advanced oxidation processes (SR-AOPs) can be combined to efficiently remove organic pollutants. Immobilizing metal oxide catalysts on ceramic membranes can enhance membrane separation technology by enabling catalytic oxidation without the need for recovering suspended catalysts. Co3O4 ceramic catalytic membranes with different Co loadings were successfully fabricated and demonstrated uniform distribution of Co3O4 nanoparticles for catalytic oxidation of 4-hydroxybenzoic acid (HBA). Mechanistic studies identified both SO4 center dot- and (OH)-O-center dot as reactive radicals, with SO(4)(center dot-) playing the dominant role in the catalytic process.
