Slurries with high solid loading and low apparent viscosity are critical for spontaneous coagulation casting (SCC) and other in situ slurry solidification techniques. When the solid loading of slurry is increased, it helps to reduce the drying shrinkage of wet body, the sintering shrinkage of green body and accelerate the densification process of ceramics. In recent years, many scholars have dedicated to increasing the solid loading of the alumina ceramic slurry. However, there is no breakthrough about an alumina slurry with both high solid loading and low apparent viscosity. An excessively high apparent viscosity will make it difficult to debubble, thereby reducing the density of the green body.
Antimicrobial resistance has become one of the top global public health and development threats due to the misuse and overuse of antimicrobials in humans, animals, and plants. Researchers are leveraging artificial intelligence and interdisciplinary approaches to design antimicrobial peptides (AMPs) that show a reduced risk of inducing resistance. Precise targeting design makes AMPs more efficient for combating drug-resistant bacteria and fungi, with applications spanning medicine, agriculture, and food safety.
This article discusses the transformative role of spatial metabolomics in advancing research on "food-medicine homology." By integrating metabolomics with spatial analysis technologies, this approach preserves the original spatial distribution information of metabolites within tissues, enabling a paradigm shift from mere component identification to precise localization. The paper highlights that food-medicine homology substances exhibit multi-component synergies, spatiotemporal dynamics, and strong environmental dependencies. Spatial metabolomics allows visual tracking of the absorption, distribution, and metabolic pathways of these components in vivo, reveals interaction mechanisms among components, gut microbiota, and the host, and provides chemical evidence for evaluating the geo-authenticity of medicinal materials. Despite challenges such as high detection costs and a lack of technical standardization, spatial metabolomics is poised to transition food-medicine research from macroscopic effect evaluation to microscopic spatial resolution. It holds promise for supporting personalized dietary recommendations, intelligent cultivation technologies, and the modernization of traditional medicine, ultimately contributing to global health innovation under initiatives like "Healthy China 2030."
Plant-derived Extracellular Vesicles (PDEVs)—nanoscale vesicles packed with bioactive molecules from food-medicine homology plants—offer promising applications in anti-inflammatory therapy, bone regeneration, and targeted drug delivery. However, traditional production methods suffer from severe quality fluctuations and batch-to-batch inconsistencies, limiting their use. A new study published in Food & Medicine Homology demonstrates that the Temporary Immersion Bioreactor System (TIBS) solves these critical issues through precise environmental control, enabling standardized PDEV production. This innovation paves the way for PDEVs’ industrialization and clinical translation in biomedicine.
Published in Mycology, research by an international team details the isolation (guided by molecular networking and SMART), structural elucidation, and biological evaluations for metabolites from the marine-derived fungus Aspergillus sydowii LF51, including new enantiomers (±)-aspersydonol A (1a/1b), aspersydonol B (2), and 12 known analogs (3–14).
Modern helicopters employ swept, dihedral blade-tip and nonlinear twist to enhance its aerodynamic performance, which also increase manufacturing complexity and induce significant vibratory loads, and thus vibration reduction of NTBT (New Type Blade-Tip) rotors has become a key research focus. Due to the excellent compatibility and quick response, the TEF (Trailing Edge Flap) technology is promising for rotor vibration reduction. Nevertheless, most aeroelastic researches have been focused on TEF technology or NTBT rotor, respectively, the combinations of TEF/NTBT rotor system remain hardly explored. The CFD/CSD (Computational Fluid Dynamics/Computational Structural Dynamics) method is competent to meet this challenge, which can effectively consider the unconventional blade platforms, unsteady flowfields, and structural dynamics. Therefore, the present aeroelastic study on TEF/NTBT rotor based on CFD/CSD method holds significant theoretical value and engineering importance.
Low-frequency electromagnetic response in microwave technology exhibits unprecedented demand, benefiting applications such as 5G communications, Wi-Fi, and radar systems. To date, the purest low-frequency response materials are induced by magnetic metals. However, magnetic metals will demagnetize at high temperatures and cannot serve in high-temperature environments. Here, we introduced a SiC/CoSi/CeSi composite co-modified with transition metal Co and rare earth metal Ce, achieving a 14-fold increase in reflection loss (RL) from -4.74 dB to -66.48 dB. The effective absorption bandwidth (EAB, RL≤-10 dB) is 2.46 GHz. With the SiC/CoSi/CeSi composite, the effective absorption frequency is shifted to the low-frequency band (3.65 GHz), and the high-temperature stability (500 °C) is maintained, inheriting 94.5% effective absorption. Radar cross-section (RCS) simulation further confirms the excellent stealth capability of the composite, reducing the target reflection intensity by 22.7 dB m2. Mechanism investigation indicates that the excellent EMW absorption performance of the composite is attributed to multiple reflections and scattering, conduction losses, abundant interface polarization, and good magnetic loss. This research supplies critical inspiration for developing efficient SiC-based absorbers with both low-frequency and high-temperature responses.
High-entropy doping (HED) effectively enhances microwave absorption in materials. However, achieving HED in MoS2 without phase interference and clarifying its absorption mechanisms remain challenging. This work develops a modular doping process to incorporate multiple dopants into 1T-MoS₂. Multi-element co-doping induces lattice strain and charge redistribution, significantly improving dipole polarization loss. The optimized WVNbTaRu-MoS2 achieves an absorption bandwidth of 7.65 GHz, over double that of undoped MoS2. Combinatorial screening proposes 31 configurations and validates 9 variants, establishing a design framework for advanced MoS2-based absorbers and providing new pathways for performance-oriented microwave absorber design
Researchers from DTU, EPFL and ESRF have developed a new in-operando two-dimensional X-ray imaging technique that reveals how salt formation happens in CO2 electrolyzers during operation. By mapping salt buildup and water distribution with micrometer resolution, the team discovered that salt accumulates preferentially under gas-flow channels rather than land areas. This insight provides a critical step toward designing more stable and durable electrolyzers, paving the way for efficient large-scale CO2 conversion into fuels and chemicals.
High brightness far-red light plays a crucial role in enhancing photosynthetic efficiency and crop yield in plant factories. Here, Cr3+-activated silicate ceramics with near-unity internal quantum efficiency and negligible thermal quenching were developed through full crystallization of glass precursors. Importantly, Ba2+ substitution for Ca2+ in Y2CaAl4SiO12:Cr3+ strengthens the local crystal field, tuning the emission into a narrow far-red band well matched with phytochrome absorption. The optimized ceramics enable 27% wall-plug efficiency in far-red pc-LEDs and record 2.1 W output in laser-driven sources, highlighting their potential as robust all-inorganic color converters for high-power plant-growth lighting.
