This study explores the use of thermally treated granite slurry waste to mitigate the mineralization of sisal fibers in fiber-cement composites. Granite waste was thermally treated at 600°C and 900°C, and the treated materials were analyzed using X-ray fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). Sisal fibers, alkali-treated with 1.7% NaOH, were incorporated into fiber-cement composites, where 15% and 30% of the cement was replaced by treated and untreated granite. Composites with 15% of granite treated at 600°C and 900°C showed improvements in compressive strength of up to 12% and 18%, respectively, compared to the control. The flexural strength increased by 10% with 15% granite treated at 900°C. However, the untreated granite at 30% replacement increased porosity by 25% and water absorption by 18%, negatively affecting the mechanical properties. Aging tests showed a 40% loss in compressive strength, while composites with 30% granite treated at 900°C maintained their flexural strength, making them more durable. These findings highlight the potential of thermally treated granite waste to enhance the sustainability and performance of fiber-cement composites in construction. © 2025 The Author(s).

Corrosion is one of the most critical problems affecting the structural integrity of metals. Polymeric nanocomposite coatings reinforced with anti-corrosive pigments are currently being used to mitigate corrosion. This study involves the synthesis of polyaniline (PANI) nanoparticles and their modification with dodecylamine (DOC), which functions as a corrosion inhibitor. Polyurethane coatings (PU-PANI@DOC) were developed by incorporating modified nanoparticles (PANI@DOC) into the polyurethane matrix, and blank polyurethane coatings (PU-blank) were prepared without any nanoparticles. Fourier-transform infrared spectroscopy (FTIR), Transmission electron microscopy, and Scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM/EDX) analysis confirmed the successful modification of dodecylamine (DOC) with the surface of polyaniline (PANI) nanoparticles. The electrochemical impedance spectroscopy (EIS) and salt spray test (SST) revealed that the impedance values of the modified coating follow an inclined trend (1010 Ω.cm2) in comparison with PU-blank coatings (107 Ω.cm2) after the 14th day of immersion in 3.5 wt% NaCl. Moreover, the hydrophobic characteristics of PANI@DOC nanoparticles shift the contact angle from 60° to 90°, thus lowering the wettability nature of modified coatings. Overall, Polyurethane coatings (PU-PANI@DOC) exhibiting potential attributes such as barrier properties, hydrophobic nature, inhibition effect, and high compatibility with polyurethane matrix can be a suitable material for the development of smart self-healing coatings to protect the metals from the hostile effects of corrosion. © 2025 Elsevier Ltd

Reconfiguring Surface Acoustic Wave Microfluidics via In Situ Control of Elastic Wave Polarization

Physical Review Letters 2025年第3期134卷 037002-037002页

Rady Department of Mechanical Engineering University of Colorado Boulder Colorado 80309 USA Institute for Microelectronics and Microsensors Johannes Kepler University Linz Austria Biomedical Engineering Program University of Colorado Boulder Colorado 80309 USA Materials Science and Engineering Program University of Colorado Boulder Colorado 80309 USA BioFrontiers Institute University of Colorado Boulder Colorado 80309 USA

We demonstrate in situ control of the elastic wave polarization in a surface acoustic wave (SAW). It allows us to create highly reconfigurable SAW microfluidics that can be switched on demand between the acoustohydrodynamic (AHD) regime and electrohydrodynamic (EHD) regime for manipulating particles and cells. The control of wave polarization comes from our experimental and theoretical identification of an unexpected shear-horizontal (SH) wave mode in a conventional Rayleigh (R) wave design, which is stereotyped to excite only vertically polarized Rayleigh SAWs. The SH wave mode is predominantly horizontally polarized and can be selectively excited to propagate in the same direction as the Rayleigh SAW. Such a selective wave generation between the SH mode and R mode allows for reconfiguration between AHD and EHD regimes that leads to unprecedented colloidal patterns and assembly dynamics. Such a reconfiguration of the particle manipulation mechanism can be explained by the controllable competition or synergism between the coexisting acoustic and electric fields. Remarkably, in the EHD regime, a virtual zero-boundary electric quadrupole is created, and a novel colloidal diamond-shaped assembly is observed in this piezoelectric-quadrupole trap, which was rarely reported in acoustic or electric microfluidics. The presented in situ control of polarization revolutionizes our understanding of SAW and acoustofluidics, expands its potential by assuming the advantages of AHD and EHD on demand, and inspires new strategies in micro- and nanoscale manufacturing and manipulation, with applications beyond fundamental scientific interest.

AISI D2 tool steel was fabricated using metal-materials extrusion additive manufacturing (M−MEX), followed by heat treatment to optimize its microstructure and mechanical properties. These were compared with conventional wrought D2 materials. The as-sintered M−MEX D2 showed a pearlite matrix with a higher fraction of low-angle boundaries and developed substructures, in contrast to the fully ferrite matrix of the as-fabricated wrought D2. MEX D2 also retained near-spherical carbides (2–5 μm), evenly distributed as in the starting powder, whereas wrought D2 contained coarse carbides exceeding 5 μm, often reaching tens of μm. After heat treatment, both materials transformed into fully lath martensite with sub-micron carbide precipitation. Heat-treated MEX D2 achieved a tensile strength of ∼ 2.09 GPa and elongation of 1.27 %, representing a 15.5 % increase in strength and 170 % increase in elongation compared to heat-treated wrought D2 (1.81 GPa and 0.47 %). Fractography revealed extensive carbide fracture in wrought D2, whereas MEX D2 exhibited limited carbide cracking, with matrix substructure dominating the fracture surface. These results demonstrate that the M−MEX process, combined with heat treatment, yields finer carbides, reduced carbide cracking, and significantly improved mechanical performance, highlighting its potential as a superior manufacturing route for high-strength D2 tool steel. © 2025 The Authors

Assessing the Microstructure of SnBiZn Alloys during Semisolid Treatment

Advanced engineering materials 2025年

The development of new alloys for semisolid processing is a key demand of Industry 4.0, driven by the limited knowledge in this area, particularly for Sn-based alloys. The primary goal is to design alloys suitable for thixocasting and semisolid additive manufacturing. While Zn is known to influence SnBi alloys by affecting their microstructure, wettability, and intermetallic compound formation, its impact on globule size, morphology, and microstructural coarsening/stability over aging remains largely unexplored, despite the potential implications for semisolid processability and final product reliability. In this research, stability in high-temperature experiments is verified for the Sn40Bi and Sn40Bi2Zn alloys (wt%). Five different heat treatment periods of 20, 40, 60, 90, and 120 min are applied to the samples, each subjected to its respective eutectic temperature according to CALPHAD computations. The microstructure of both alloys is characterized by Sn-rich globules for times higher than 90 min, which are noticeably finer and less elongated in the Sn40Bi2Zn alloy compared to the Sn40Bi. This globule refinement in Sn40Bi2Zn alloy can be attributed to the presence of Zn needles at the dendrite boundaries that pin the Sn-rich regions and prevent them from growing freely. Over time, while Bi saturates near its solubility limit in Sn matrix at 60 min and remains stable up to 120 min, the Sn40Bi2Zn alloy exhibits a progressive increase in Bi content between 60 and 120 min, reaching the saturation level at 120 min. The Sn40Bi2Zn alloy exhibits higher globule microhardness in the 90 min samples, primarily due to Zn hardening in solid solution. © 2025 The Author(s).

Metamaterials are a class of materials with extraordinary capabilities derived from their engineered structure. In 2017, Frenzel et al. (science 358, 2017) conceptualized “three-dimensional mechanical metamaterials with a twist,” which convert linear deformation into rotational motion—a mechanical response that surpasses the bounds of Cauchy continuum mechanics. However, the lack of suitable manufacturing technologies for producing metallic twist metamaterials has precluded their experimental validation and potential applications to date. Herein, 316L-stainless-steel twist metamaterials are fabricated at various scales using an emerging sintering-based technology—lithography metal manufacturing (LMM) —and their mechanical responses are tested using stereo digital image correlation. Results provide the first empirical evidence of compression-induced rotation in steel twist metamaterials and highlight their sensitivity to manufacturing defects.

Lithography metal manufacturing (LMM) is an emerging sinter-based additive manufacturing (AM) technology for support-free 3D printing of extremely complex parts with micrometric resolution on a decimeter scale. Although the printing phase of LMM is well-established, the sintering stage is challenging due to either high porosity or melting-induced deformation, particularly in thin-walled lattices and metamaterials. This study investigates the effects of sintering temperature on shape distortion, surface morphology, chemistry, porosity, microstructure, and mechanical properties of 316L stainless steel auxetic metamaterials 3D printed using LMM and sintered in a furnace customized for precise temperature control. Our results show that the fully dense grain microstructure with high plasticity can be sintering within 1300 – 1325 °C range. Going beyond this temperature results in shape distortion and embrittlement of the steel metamaterials. The previously recommended range of sintering temperatures for 316L steel, 1360 - 1380 °C need revision.

Increasing evidence is showing that per- and polyfluoroalkyl substance (PFAS) replacing compounds are not as safe as they were assumed. This study investigated the plant uptake of two most prevalent PFAS, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic (PFOS) and their replacing compounds, hexafluoropropylene oxide dimer acid (HFPO-DA or GenX) and 6:2 chlorinated polyfluoroalkyl ether sulfonates (Cl-PFESAs) (6:2 Cl-PFAES) by hydroponically grown lettuce in the presence of different nitrogen fertilizers including ammonium sulfate ((NH4)2SO4), potassium nitrate (KNO3), and urea in a growth chamber. Interestingly, (NH4)2SO4 significantly increased GenX uptake in lettuce shoots by ∼108% and KNO3 increased the uptake of PFOS and 6:2 Cl-PFAES by 267% and 395%, respectively, suggesting that the nitrogen fertilizer type has a marked impact on the plant uptake of PFAS and that this impact was PFAS-dependent. Our results also showed that (NH4)2SO4 generally resulted in higher PFAS root to shoot transfer than the other two types of nitrogen fertilizers. Metabolomic analysis revealed that amino acids, nucleotides, and antioxidants are the major metabolites that were either significantly increased or decreased in the lettuce shoots. These results showed that nitrogen fertilization management can have a significant impact on PFAS plant uptake and transport, and the impact depends on the types of nitrogen fertilizer and PFAS compounds. © 2025 The Authors.

A Runaway Electron Avalanche Surrogate for Partially Ionized Plasmas

arXiv 2025年

A physics-constrained deep learning surrogate that predicts the exponential "avalanche" growth rate of runaway electrons (REs) for a plasma containing partially ionized impurities is developed. Specifically, a physics-informed neural network (PINN) that learns the adjoint of the relativistic Fokker-Planck equation in steady-state is derived, enabling a rapid surrogate of the RE avalanche for a broad range of plasma parameters, motivating a path towards an ML-accelerated integrated description of a tokamak disruption. A steady-state power balance equation together with atomic physics data is embedded directly into the PINN, thus limiting the PINN to train across physically consistent temperatures and charge state distributions. This restricted training domain enables accurate predictions of the PINN while drastically reducing the computational cost of training the model. In addition, a novel closure for the relativistic electron population used when evaluating the secondary source of REs is developed that enables improved accuracy compared to a Rosenbluth-Putvinski source. The avalanche surrogate is verified against Monte Carlo simulations, where it is shown to accurately predict the RE avalanche growth rate across a broad range of plasma parameters encompassing distinct tokamak disruption scenarios. © 2025, CC BY.
