In this study, we propose a brand-new beam shaping method that is capable of generating adjustable focus Gaussian-ring mode (AFGRM) lasers by combining Gaussian mode lasers and ring mode lasers with different focal lengths. Based on proposed ringing algorithm, a customized mono-freeform-mirror is obtained, which can realize collimating, shaping, and focusing effects from Gaussian laser source to AFGRM laser. By virtue of this mono-freeform-mirror, the AFGRM laser with customized focal lengths, ring mode radius, and Gaussian-ring power ratio can be applied in laser welding process. Here, we designed and manufactured 4 pieces of mono-freeform mirrors with collimation length of 125 mm, Gaussian mode focal length of 300 mm, ring mode focal length of 297 mm, ring mode radius of 0.3 mm, and power ratio settings of 8:1, 8:2, 8:3 and 8:4. The optical propagation simulation and focus analysis were implemented, and the matching results presented good propagation stability and beam quality. Moreover, bead-on-plate welding experiments on 16 mm SUS304 plates utilizing conventional Gaussian lasers and AFGRM lasers were carried out, under the condition of same central Gaussian mode power and same total power. With the optimal power ratio of 8:2, the weld depth and pore proportion obtained by 10 kW AFGRM laser exhibited 37.0 % and 98.6 % improvement compared to 8 kW conventional Gaussian laser, 11.0 % and 98.2 % improvement compared to 10 kW conventional Gaussian laser, respectively. We believe that through this novel beam shaping method, laser beams with various spatial energy distributions can be obtained which will exhibit their unique advantages in laser welding and other processing fields. © 2025 Elsevier Ltd

The simultaneous presence of heavy metal ions and organic dyes presents significant challenges for the wastewater treatment sector. In response to this pressing issue, a novel composite aerogel has been developed: polyethyleneimine-modified sodium alginate/carboxylated chitosan/attapulgite aerogels (ATP/CCS/SA-PEI), which effectively facilitates the concurrent removal of copper ions (Cu(II)), Congo red (CR), and methylene blue (MB) from aqueous solutions. Under optimal adsorption conditions, ATP/CCS/SA-PEI exhibits superior adsorption capacities for Cu(II), MB, and CR when compared to the unmodified raw materials at equivalent dosages, achieving maximum capacities of 228.24 mg/g for Cu(II), 206 mg/g for MB, and 290.13 mg/g for CR. Additionally, the presence of coexisting ions exerts a minor adverse effect on adsorption efficiency, indicating that the synthesized ATP/CCS/SA-PEI aerogels possess commendable environmental adaptability. Characterization techniques reveal that the primary mechanisms underlying adsorption involve electrostatic interactions, hydrogen bonding, coordination complex formation, and ion exchange synergies. Simultaneously, the ATP/CCS/SA-PEI aerogel exhibits significant reusability, retaining removal efficiencies of 53 % for MB and 48 % for Cu(II) after four sorption-desorption cycles. Consequently, the synthesized ATP/CCS/SA-PEI aerogel demonstrates considerable potential for the remediation of complex pollutants in wastewater, indicating its applicability across diverse industrial sectors. © 2025 Elsevier B.V.

This study comprehensively investigated the effects of different ammonia nitrogen models during transportation on the energy metabolism, redox system, apoptosis, and changes in muscle quality of fish using molecular biology and metabolomics. Exposure to ammonia nitrogen caused intensive stress response as evidenced by alteration on the levels of biochemical indicators (cortisol, glucose, urea nitrogen, alanine transaminase, lactic dehydrogenase, superoxide dismutase, and glutathione peroxidase) and structural disruption of organs (including gill, cephalic kidney, kidney, and liver). As a result of the ammonia nitrogen stress, the redox system became imbalance, leading to disturbance in energy metabolism primarily through the pathways of D-amino acid metabolism, alanine/aspartate/glutamate metabolism, and purine metabolism. Additionally, apoptosis occurred following stress, regulated by FoxO, mTOR, NF-κB, and PI3K/AKT signaling pathways. Besides redox system, energy metabolism, and apoptosis, the change of muscle quality were also influenced by ammonia nitrogen concentration and exposure duration. Drip loss increased with higher ammonia nitrogen concentrations and longer exposure time, while shear force value showed an inverse trend. Although no significant changes were observed in a* and b* values following ammonia nitrogen exposure, the highest W and L* values were found in the low-concentration groups. The correlation of spearman indicates the changes in muscle quality, including drip loss, shear force, and color, induced by ammonia nitrogen during transportation was attributed to the interplay of redox system, energy metabolism, and apoptosis. © 2025 Elsevier Ltd

In this study, the Quasi-perfect optical vortex (Quasi-POV) beam with topological charge-independence radial distribution is investigated to enhance the performance of underwater wireless optical communication (UWOC) system based on spatial modes. Additionally, the oceanic channel model is modified to obtain more reliable simulation results. The propagation and communication performance of perfect optical vortex (POV) beam and Quasi-POV beam are compared and analyzed through the modified model. With the optimization of beam's parameters, Quasi-POV beam achieves lower bit-error rate (BER) and higher average capacity in multiple phase shift keying (M−PSK) modulated UWOC system. The results indicate that Quasi-POV beam receives higher normalized intensity and lower crosstalk probability than the POV beam, the average simulation results for the three topologic charge cases show that the BER of Quasi-POV beam at 100 m reduced by approximately 52%, the average capacity of Quasi-POV beam increased by approximately 13.3%. The Quasi-POV beam has better performance than the POV beam in Spatial-Mode UWOC system according to the simulation results, which is more suitable for UWOC system based on spatial modes with smaller values of topologic charge. © 2025 Elsevier Ltd

Objective: This study seeks to optimize the processing parameters for Astragalus membranaceus with rice water (AM-RW), establish quality evaluation standards, and develop a rapid multilayer perceptron (MLP) model for classification. This model facilitates accurate identification of AM-RW at various processing stages, providing a scientific reference for the quality assessment of traditional Chinese medicine products. Methods: Optimization of AM-RW was achieved using a single-factor test and Box-Behnken design response surface methodology to determine the optimal process parameters. The Watershed Algorithm was applied to segment images of AM tablets, and the numpy and pandas libraries were used to collect color data from these tablets. The study also explored the correlation between R, G, B, and L color values and calycosin-7-glucoside content. A rapid classification model based on MLP was developed, utilizing color values, hardness values, and calycosin-7-glucoside content of AM-RW with various processing degrees. Results: The study identified the optimal parameters for AM-RW as 20 mL of rice water, a frying temperature of 180°C, and a frying time of 7 min. The average color values for the best-processed products fell within the normal distribution range: R value (94.83 ± 8.57), G value (96.1 ± 19.37), B value (36.84 ± 5.93), and L value (89.55 ± 12.24). The rapid identification model using MLP demonstrated high accuracy and reliability, achieving an accuracy rate of 94 % in the classification process. Conclusions: The response surface method effectively optimizes the precise processing parameters of AM-RW. Furthermore, the MLP-based model can accurately classify AM-RW with varying degrees of processing, providing a valuable reference for the expedited identification of processing quality in traditional Chinese medicine products. © 2025 Tianjin Press of Chinese Herbal Medicines

Excellent pyroelectric performance in environmentally friendly lead-free ferroelectrics is highly demanded for uncooled infrared detector. However, the trade-off between room temperature pyroelectric coefficient (proom) and depolarization temperature (Td) remains a major challenge of lead-free ferroelectrics for their device applications. Herein, a superior proom of 13.8 × 10−4 C m−2 K−1 with high Td of 155 °C is achieved in quenched BNT-Fe/Mn-NBT sample. Oxygen vacancy engineering is proposed to solve the constraint between proom and Td in BNT-based ceramics. The local A/B site displacement and oxygen vacancies are constructed in the BNT-Fe/Mn-NBT perovskite structure by quenching treatment, resulting in larger lattice distortion and superior proom. Meanwhile, defect-induced inhomogeneous random field compensates the ferroelectric depolarization field and down-shifts the free energy well, maintaining high Td. The resulting pyroelectric infrared detector made from the high-performance quenched BNT-Fe/Mn-NBT generates the voltage responsivity of 5906 V W−1 and specific detection rate of 1.8 × 108 cm Hz1/2 W−1, which is comparable to the commercial RD-624 type PZT-based pyroelectric infrared detector. © 2025 Wiley-VCH GmbH.

Temperature kinetics of calcium-activated burnt coal cinder-based geopolymer: Reaction medium and curing temperature

In various regions and seasons, the impact of environment temperature on the reaction medium must be considered in industrial applications and how to determine the optimal curing system to ensure product performance. Within this context, this study focused on the temperature kinetics of calcium-activated low-activity solid waste-based geopolymers and assessed the impact of reaction medium temperature (RMT) and curing temperature (CRT). The influence of RMT during preparation was determined by the hydration heat and slurry fluidity. Moreover, a prediction-judgment model for geopolymer properties, using water absorption as an indicator, was developed to inform CRT system selection. Techniques like XRD, TA, and BJH analysis verified the model's judgment on geopolymer phase and structural changes at various CRT. Results showed the optimal RMT was about 20℃, with deviations reducing slurry workability. During curing, higher CRT accelerated chemical reactions and microstructure evolution. Nevertheless, the prediction-judgment model suggests that there exists a curing time threshold under specific CRT. Curing time beyond this threshold may even have detrimental effects. Given the continuity of temperature, it is essential that changes in threshold values are also continuous. To depict this continuous change, extended mathematical thought is used to map the values on the number line onto the "loop". Changes in CRT cause negatively correlated changes in the threshold within this loop. When CRT is below the critical level, the threshold crosses the top of the loop to become negative, signaling geopolymer structural degradation. Meanwhile, the micro-mechanism analysis shows that proper increase in CRT boosts the geopolymerization rate, promoting rapid and extensive formation of gel and yielding denser surfaces with more developed microstructures, thereby enhancing geopolymer properties. In contrast, lower temperatures lead to looser structures and many unreacted particles, sho

Tunable structures and single-ion magnet property in two cobalt(II) coordination compounds constructed by mixed bipyridyl- tetracarboxylic ligands

Two cobalt(II) coordination compounds, [Co(dmbpy)2(H2btca)(H2O)]·H2O (1, dmbpy = 5,5′-Dimethyl-2,2′-bipyridine, H4btca = 1,2,4,5-benzenetetracarboxylic acid) and {[Co(dmbpy)(btca)1/2(H2O)2]}n (2), were structurally and magnetically reported. Single-crystal X-ray diffraction unambiguously establishes that compound 1 adopts a mononuclear structure, contrasting with the one-dimensional coordination polymer architecture of 2. The latter displays a rare ribbon-like topology characterized by octahedrally coordinated Co²⁺ centers. Magnetic susceptibility analyses reveal that both Co²⁺ ions reside in distorted octahedral geometries, though with distinct deviations. Detailed magnetic studies quantify significant easy-plane anisotropy in both complexes, with axial zero-field splitting parameters D = + 61.3 cm⁻¹ for 1 and D = + 72.6 cm⁻¹ for 2. Field-dependent ac susceptibility measurements confirm the emergence of slow magnetic relaxation in both systems under a 1000 Oe dc field, with disparate temperature-frequency correlations indicating distinct relaxation pathways. These observations collectively demonstrate single-ion magnet (SIM) behavior in both cobalt(II) complexes. The structural dichotomy between mononuclear 1 and polymeric 2 directly correlates with their divergent relaxation dynamics, highlighting the critical role of dimensionality in modulating SIM performance. This work not only provides two new cobalt(II) complexes showing SIM property but also demonstrates a bipyridyl-tetracarboxylic strategy for constructing a structurally adaptable SIM platform. © 2025 Elsevier B.V.

Ethnopharmacological relevance: Age-related cognitive decline and neuroinflammation are significant contributors to neurodegenerative diseases. In Traditional Chinese Medicine, aging is often associated with “kidney deficiency,” a concept linked to impaired bone marrow production and brain function. Epimedii Folium and Curculiginis Rhizoma (XY), a classic herbal pair used to tonify the kidney, are traditionally employed to enhance vitality, bone health, and cognitive function. While previous studies suggest XY's efficacy in pathological models, its impact on natural aging process requires further investigation. Aim of the study: This study aimed to investigate the neuroprotective effects of XY against cognitive impairment and neuroinflammation in naturally aged mice and to explore the underlying mechanisms. Materials and methods: Network pharmacology was used to identify potential targets and pathways, while molecular docking assessed the binding interactions between active compounds from XY and key target proteins. Naturally aged mice were orally treated with XY (2.34, 4.68 g/kg/day) for 26 days. Cognitive function was assessed using behavioral tests. Histological analysis, ELISA, real-time PCR, and Western blotting were employed to evaluate hippocampal neuronal damage, inflammatory markers, senescence-related proteins, and NLRP3 inflammasome components. Results: Network pharmacology identified key targets and pathways associated with aging and neuroinflammation. Molecular docking confirmed strong binding affinities between active components (e.g., Icariin, Epimedin B, Epimedin C) and relevant protein targets. In vivo, XY treatment significantly improved cognitive performance, ameliorated hippocampal neuronal damage, and suppressed microglial activation in aged mice. Furthermore, XY downregulated the expression of senescence markers (p53, p21, p16, CDK6), pro-inflammatory cytokines (IL-1β, TNF-α, IL-6, IFN-γ), factors associated with the senescence-associated secre
