Summary: Agriculture-related manufactured nano-objects (MNOs) have the potential to revolutionize crop production and contribute to sustainable development goals. With their diverse physico-chemical properties and ability to deliver active ingredients in a controlled manner, MNOs can enhance efficiency while minimizing harm to non-target organisms and the environment. However, further research is needed to understand the effects of MNOs on soil microbial communities under different conditions. Integration of advanced technologies such as omics, artificial intelligence, and statistical frameworks is crucial to comprehending the complex mechanisms and factors involved in MNOs-microbial interactions. Manipulating soil microbiomes through MNOs could lead to improved microbial services and transform agriculture for sustainable development.

Summary: This review provides a comprehensive overview of the toxic effects of MNOs on earthworms in the soil system, highlighting the potential risks associated with their production, release, and bioaccumulation in agricultural soil. It also emphasizes the lack of long-term toxicological data to fully characterize the risks of MNOs, as well as the need for a better understanding of the mechanisms causing toxicity to earthworm species. Investigating the interaction between bio-nano in the soil environment will improve our understanding for safer applications of MNOs in agriculture.

Summary: The presence of natural organic matter (NOM), modeled by humic acid (HA), can mitigate the acute toxicity of amino-functionalized polystyrene nanoplastics (PS-NH2) to green microalga Chlorella vulgaris, reducing cellular aggregation and cell size reduction. Higher concentrations of HA are more effective in reducing the toxicity of PS-NH2. The formation of cellular aggregates under the influence of PS-NH2 is likely related to the electrostatic attraction between the positively charged surfaces of the particles and the negatively charged polysaccharide walls of C. vulgaris.

Summary: A new nano-scale rhombic precipitate was discovered in SiC with 8 wt% Mg additive. TEM was used to characterize the distribution, shape, size, and microstructure of the precipitates, as well as to determine its formation mechanism. The rhombic precipitates were found to be under 65 nm in size and extensively distributed with high density. They contained a significant amount of Fe from the collision between the stainless steel pot and the milling balls, as well as Fe3Si generated during sintering. The Fe3Si precipitates and SiC matrix exhibited specific crystal orientations.

Summary: The micro/nano-scale porous CoAl intermetallic compound (IMC) was fabricated using the thermal explosion method combining space holder. The link between the structure of the pores and the permeability performance of the product was established through 3D-XRM analysis. Oxidative corrosion tests were conducted at 600 degrees C for 120 hours in static air, revealing two stages of corrosion dominated by O reaction and Al diffusion. This integrated porous CoAl structure-function will provide a new pathway for industrial-scale high-temperature oxygenated gas filtration.

Summary: This study developed a novel CoCrNiAl based eutectic medium/high-entropy alloy (E-M/HEAs) using a high-throughput method based on compositionally graded materials by laser directed energy deposition. The alloy displayed a eutectic lamellar microstructure with face-centered cubic (FCC) and ordered body-centered cubic (B2) phases, leading to a better strength-ductility combination compared to other reported eutectic alloys. The improvement in mechanical properties can be attributed to the hierarchically nano-lamellar microstructure of the alloy.

Summary: Understanding the bioelectrical properties of bone tissue is crucial for the development of new treatment strategies for bone diseases and injuries, as well as for improving the design and fabrication of scaffold implants in bone tissue engineering. The bioelectrical properties of bone tissue result from the interaction of its various cell lineages and the surrounding extracellular matrix, in response to biomechanical stimuli. These properties can be described as a combination of dielectric, piezoelectric, pyroelectric, and ferroelectric properties, as well as streaming potential and electro-osmosis. The complex interaction between the organic and non-organic components of bone defines its electrophysiological properties, which play a significant role in its metabolism, homeostasis, and regeneration.

Summary: In this study, a double-scatterer structure is proposed to achieve complete conversion of elastic bulk waves. Each unit of the elastic metamaterial slab contains a pair of scatterers with a relatively oblique direction. When attached to a semi-infinite solid background, the slab can completely convert the normal incident longitudinal wave into a reflected shear wave, or vice versa. The conversion is attributed to the in-phase coupling of the double scatterers' quadrupolar resonances, resulting in oblique displacements and horizontal displacements for reflected waves.

Summary: This study aimed to develop a conceptual framework to guide the future scale-up of a co-managed model of care for older patients with hip fracture by identifying barriers and enablers. Through in-depth interviews with healthcare providers and administrators, barriers such as perceived complexity of implementation and lack of digital health applications, as well as enablers such as hospital authority support and sufficient skilled health providers, were identified. A conceptual framework with essential components was developed to guide the implementation of co-managed care in other hospitals.

Summary: Compared with other denoising algorithms, wavelet denoising is preferable. The wavelet function and decomposition level greatly influence the quality of denoising; however, determining the wavelet function and decomposition level is challenging in actual X-fluorescence spectral denoising. This paper proposes a wavelet algorithm based on Russian roulette optimization for X-ray spectral denoising to address this problem.

Summary: This study analyzed data from 145 newly diagnosed multiple myeloma (MM) patients and found a correlation between red blood cell distribution width to platelet ratio (RPR) and disease prognosis. Patients in the high RPR group were more likely to have anemia, thrombocytopenia, and high beta 2-macroglobulinemia, as well as higher percentages of bone marrow plasma cells and advanced disease stage. The incidence rates of CD56-positive, D13S319-positive, RB1-positive, and 1q21 amplification were also significantly higher in the high RPR group. Survival analysis showed that patients in the high RPR group had significantly shorter progression-free survival and overall survival. Multivariate analysis confirmed RPR >= 0.12, D13S319-positive, and 1q21 amplification as independent poor prognostic factors.

Summary: In this paper, a new TF analysis method called statistic synchrosqueezing transform (Stat-SST) is proposed to characterize the fast varying IF of noisy signals in a concentrated and noise-reduced way. Stat-SST improves the performance of the IF estimator of SST by defining the instantaneous frequency band (IFB) and its width, and enhances the concentration of TFR by redistributing TF coefficients. By using a threshold obtained by IFB width, Stat-SST distinguishes signal from noise and greatly reduces noise. The validation with both numerical simulation data and practical aero-engine data shows that Stat-SST is superior, more concentrated, and more robust to some existing TFA methods, especially when analyzing signals with fast varying IF.

Summary: By introducing Rb+ ions, the PCN photocatalyst was modified to have more edge active sites and improved hydrophilicity and O2 adsorption capacity, leading to a higher H2O2 yield. Experimental and theoretical results showed that CNR-0.5 followed a two-step single-electron O2 reduction reaction pathway in the H2O2 photogeneration reaction. CNR-0.5 exhibited excellent photocatalytic H2O2 production performance in a real water body, expanding the practical applications of PCN materials.
