Within the framework of green chemistry, additive-free and morphology-controllable synthesis of inorganic nanomaterials has become an emerging research frontier. In this study, we developed an efficient liquid-phase synthesis route using calcium hydroxy glycolate (CHG) as the calcium source, sulfuric acid as the sulfur source, and ethylene glycol as the solvent. Under ultrasound-assisted conditions, without the use of soluble salts or surfactants, high-purity nano-anhydrite calcium sulfate (CaSO₄) was successfully synthesized. By systematically varying the precursor concentration and ultrasonic parameters, the resulting products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR), which confirmed the formation of spherical, plate-like, and rod-shaped nano-anhydrite. Specifically, by adjusting the Ca²⁺ concentration, rod-like crystals (length: 300–450 nm, width: 50 nm, aspect ratio: 7), spherical particles (mean diameter: 23.19 nm), and flake-like structures (diameter: 115.40 nm, thickness: 10–30 nm) were obtained at 0.3, 0.5, and 0.7 mol·L⁻¹, respectively. The smallest particle sizes across these morphologies were achieved under optimized ultrasonic conditions of 750 W for 30 min. Molecular dynamics simulations revealed that ethylene glycol concentration modulates its selective adsorption on specific crystal planes of anhydrite, thereby differentially inhibiting growth rates along certain directions and enabling morphology-controlled synthesis. The simulated adsorption energies for the (200), (020), (011), and (002) faces were −15.04, −7.96, −2.08, and −0.45 kJ·mol⁻¹, respectively. These results indicate that preferential adsorption occurs particularly on the (200) and (020) planes. This integrated experimental and simulation study elucidates the coupled mechanism of “precursor concentration − crystal plane adsorption − ultrasonic dynamics,” offering theoretical insights and technical support for the environmentally sustainable and controllable synthesis of nano-anhydrite and other sulfate-based nanomaterials.

在绿色化学的框架下，无添加剂、形态可控的无机纳米材料合成已成为一个新兴的研究前沿。本研究以羟基乙醇酸钙（CHG）为钙源，硫酸为硫源，乙二醇为溶剂，建立了一种高效的液相合成路线。在超声辅助条件下，在不使用可溶性盐和表面活性剂的情况下，成功合成了高纯度的纳米硬石膏硫酸钙（CaSO4）。通过系统地改变前驱体浓度和超声参数，对产物进行了x射线衍射（XRD）、扫描电镜（SEM）和傅里叶变换红外光谱（FT-IR）表征，证实产物形成了球形、片状和棒状纳米硬石。其中，通过调节Ca2+浓度，在0.3、0.5和0.7 mol·L−1的浓度下，分别获得了棒状晶体（长度300-450 nm，宽度50 nm，长径比7）、球形颗粒（平均直径23.19 nm）和片状结构（直径115.40 nm，厚度10-30 nm）。在优化的750 W超声条件下，在30分钟内获得了这些形貌上最小的颗粒尺寸。分子动力学模拟表明，乙二醇浓度可调节其在硬石膏特定晶体平面上的选择性吸附，从而在特定方向上抑制生长速率并实现形态控制合成。（200）、（020）、（011）和（002）面的模拟吸附能分别为−15.04、−7.96、−2.08和−0.45 kJ·mol−1。这些结果表明，优先吸附主要发生在（200）和（020）平面上。本实验与模拟相结合的研究阐明了“前驱体浓度-晶面吸附-超声动力学”的耦合机理，为环境可持续可控合成纳米硬石膏和其他硫酸盐基纳米材料提供了理论见解和技术支持。

The efficient treatment of aged oily sludge, a challenging by-product of the petroleum industry, is crucial for resource recovery and environmental protection. Conventional methods often suffer from limited oil recovery efficiency. This study proposes a novel application of jet cavitation technology to disintegrate aged oily sludge, aiming to enhance oil recovery and reduce petroleum hydrocarbon content. The mechanism of disintegration involves both mechanical and chemical effects: the mechanical forces destroy hydrogen bonds to facilitate oil phase desorption, while cavitation-induced chemical bond rupture and free radical oxidation degrade long-chain hydrocarbons into short-chain compounds. The physicochemical properties (oil components, functional groups, petroleum hydrocarbons) of the sludge were comprehensively analyzed before and after treatment using multi-scale characterization techniques, including laser particle sizing, contact angle and Zeta potential measurements, combined with Thin Layer Chromatography-Flame Ionization Detection (TLC-FID), Fourier Transform Infrared Spectroscopy (FT-IR), and Gas Chromatography-Mass Spectrometry (GC–MS). Under optimized conditions (inlet pressure of 14.9 MPa, jet water temperature of 40°C, sludge concentration of 21.16%, hydraulic retention time of 5.98 s, and sludge temperature of 50°C), a maximum oil recovery rate of 84.95% was achieved. This result is significantly superior to the efficiency obtained via ultrasonic cavitation treatment, demonstrating the notable advantage and potential of the jet cavitation method for the effective treatment of aged oily sludge.

老化含油污泥是石油工业中具有挑战性的副产品，其有效处理对资源回收和环境保护至关重要。常规方法的采收率往往有限。本研究提出了一种新的应用射流空化技术来分解老化的含油污泥，以提高石油采收率和降低石油烃含量。分解机理包括机械和化学两方面的作用：机械力破坏氢键促进油相脱附，而空化引起化学键断裂和自由基氧化使长链烃降解为短链化合物。采用多尺度表征技术，包括激光粒度、接触角和Zeta电位测量，结合薄层色谱-火焰离子化检测（TLC-FID）、傅里叶变换红外光谱（FT-IR）和气相色谱-质谱（GC-MS），综合分析处理前后污泥的理化性质（油组分、官能团、石油烃）。在进口压力14.9 MPa、喷射水温40℃、污泥浓度21.16%、水力滞留时间5.98 s、污泥温度50℃的优化条件下，最大采收率为84.95%。这一结果明显优于超声空化处理的效果，说明了射流空化法有效处理老化含油污泥的显著优势和潜力。

This study explores the effects of ultrasound-assisted heating compared to conventional wet heating on the Maillard reaction (MR) between brewer’s spent grain (BSG) protein and gum arabic (GA), focusing on various factors like reaction kinetics, structural changes, emulsifying performance, and volatile formation. Ultrasound process markedly accelerated glycation, with a 45 min sonicated sample glycation to a similar degree to that induced by traditional 3 h treatment, such that cavitation facilitates early MR pathways. Both approaches enhanced solubility and remodeled secondary structures, although in different manners: conventional heating promoted a gradual increase in β-sheet content and a decrease in α-helix content, while ultrasound induced rapid unfolding and structural reorganization. All MRPs enhanced the emulsifying properties, but the conventional sample after 3 h obtained the highest emulsifying activity index (EAI) and emulsion stability index (ESI) values. Samples treated with ultrasound showed moderate improvement, however, at considerably reduced reaction times. Dynamic light scattering (DLS) and fluorescence microscopy have also confirmed that conventionally heated MRPs form smaller and more uniform droplets. Volatile profiling indicated that conventional heating produced a broader spectrum of aldehydes, ketones, and furans associated with off-flavors, whereas ultrasound greatly reduced compounds such as (E,E)-2,4-decadienal and 2-pentylfuran, indicating a flavor-protective potential. In general, the reaction efficiencies and flavor quality of ultrasound-assisted heating are higher, and emulsifying performance is optimized by the conventional heating technology. This work shows that BSG protein–GA conjugates are versatile enough to achieve clean-label, plant-based emulsifier applications and its desired functional/sensory properties.

本研究探讨了超声辅助加热与传统湿法加热相比对啤酒废谷物（BSG）蛋白与阿拉伯胶（GA）之间美拉德反应（MR）的影响，重点研究了反应动力学、结构变化、乳化性能和挥发性形成等各种因素。超声处理显著加速糖基化，45分钟超声处理的糖基化程度与传统3小时处理的糖基化程度相似，因此空化有利于早期MR通路。两种方法都能提高溶解度，重塑二级结构，但方式不同：常规加热促进β-片含量逐渐增加，α-螺旋含量逐渐减少，而超声诱导快速展开和结构重组。所有MRPs均增强了乳化性能，但常规样品在3 h后获得最高的乳化活性指数（EAI）和乳液稳定性指数（ESI）值。然而，用超声波处理的样品在相当短的反应时间内显示出适度的改善。动态光散射（DLS）和荧光显微镜也证实了常规加热的MRPs形成更小更均匀的液滴。挥发性分析表明，传统加热会产生与异味相关的更广泛的醛、酮和呋喃，而超声波则会大大减少（E，E）-2,4-十烯醛和2-戊基呋喃等化合物，表明其具有保护风味的潜力。总的来说，超声辅助加热的反应效率和风味品质较高，并通过常规加热技术优化乳化性能。这项工作表明，BSG蛋白- ga偶联物是通用的，足以实现清洁标签，植物为基础的乳化剂应用及其所需的功能/感官特性。

Chemical milling (CHM) is widely used for thinning and pocketing components, especially in aerospace applications, but its low material removal rate (MRR) requires high etchant consumption and often leads to poor surface integrity. This study introduces a novel method, direct ultrasonic-assisted chemical milling (UACM), as an efficient and sustainable alternative to CHM. A full-factorial design examined three ultrasonic powers (50, 150, 250 W) across acidic and alkaline etchants at three concentration levels. MRR and roughness parameters (Ra, Rz, Sa) were experimentally quantified and modeled using ANOVA-based regression, while multi-region SEM/EDS elucidated oxide disruption, pit formation, and surface evolution on Al 6061. In 10 % HCl at 250 W, UACM increased MRR by 591 % through cavitation-enhanced agitation and rapid renewal of reactive species, enabling≈85.5 % reduction in acid use. Moreover, at matched MRR, UACM yielded 15–30 % lower Sa than CHM, producing uniform microporosity beneficial for bonding and coating applications. The best acidic condition was 15 % HCl at 250 W, where MRR increased from 0.70 to 1.30 mm/m/s and produced a clean, crack-free, homogeneous surface with optimal integrity. The optimal alkaline condition was 50 % NaOH at 250 W, where MRR increased from 0.08 to 0.23 mm/m/s (≈65.2 % time reduction), and the disruption of hydrogen-bubble shielding generated a uniform and stable morphology. Key experimental challenges included maintaining thermal stability under high acoustic power, controlling bubble adhesion in alkaline media, and achieving a reproducible initial surface. Overall, UACM substantially enhances removal efficiency, improves surface integrity, and reduces chemical consumption, offering a practical pathway toward high-precision and greener manufacturing.

化学铣削（CHM）广泛用于减薄和装袋部件，特别是在航空航天应用中，但其低材料去除率（MRR）需要高蚀刻剂消耗，并且往往导致表面完整性差。本研究介绍了一种新的方法，直接超声辅助化学磨粉（UACM），作为一种高效和可持续的替代中药。全因子设计检测了酸性和碱性腐蚀剂在三种浓度水平下的三种超声波功率（50、150、250 W）。MRR和粗糙度参数（Ra, Rz, Sa）通过实验量化和基于方差分析的回归建模，而多区域SEM/EDS阐明了Al 6061的氧化物破坏，坑形成和表面演化。在250 W、10 % HCl条件下，UACM通过空化强化搅拌和反应物质的快速更新，使MRR提高了591 %，使酸用量减少了约85.5 %。此外，在匹配的MRR下，UACM的Sa比CHM低15-30 %，产生均匀的微孔隙，有利于粘接和涂层应用。最佳酸性条件为15 % HCl， 250 W， MRR从0.70增加到1.30 mm/m/s，可获得干净、无裂纹、均匀且完整性最佳的表面。在250 W下，NaOH浓度为50 %，MRR从0.08提高到0.23 mm/m/s（时间减少约65.2 %），破坏氢泡屏蔽后形貌均匀稳定。关键的实验挑战包括在高声功率下保持热稳定性，控制碱性介质中的气泡粘附，以及实现可复制的初始表面。总的来说，UACM大大提高了去除效率，改善了表面完整性，减少了化学品消耗，为高精度和绿色制造提供了切实可行的途径。

Lactobacillus-fermented soymilk can improve texture and flavor through microbial metabolism. The application of processing techniques that preserve the nutritional value, quality, and bioactive properties of fermented soymilk without compromising their integrity is of great significance. Ultrasound can promote the decomposition of proteins in soymilk by disrupting their structure, and also has a cell wall-breaking effect on the fermentation strains in soymilk, causing the beneficial components of the bacteria to be released into the soymilk, thereby changing the characteristics and material composition of the fermented soymilk and increasing the content of nutrients and the stability of the soymilk. This study revealed that ultrasonic treatment (150 W, 20 min) significantly improved the texture and stability of Lactobacillus gasseri JM1- fermented soymilk, reduced the viscosity of the fermented soymilk (1918.80 ± 112.33 cP), and increased the water-holding capacity of the soymilk (97.12%). Moreover, ultrasonic treatment (150 W, 20 min) also led to an increase in active aglycone isoflavones such as daidzein (17.32 μg/ml) and genistein (24.48 μg/ml) in the fermented soymilk. Metabolomics and proteomics were used to establish a metabolic network of metabolites, revealing the changes in the main metabolic substances in the fermented soymilk before and after ultrasonic treatment.

乳酸菌发酵豆浆可以通过微生物代谢改善质构和风味。采用既能保持发酵豆浆的营养价值、质量和生物活性又不损害其完整性的加工技术具有重要意义。超声波可以通过破坏豆浆中蛋白质的结构来促进其分解，同时对豆浆中的发酵菌种也有破壁作用，使细菌的有益成分释放到豆浆中，从而改变发酵豆浆的特性和物质组成，提高豆浆的营养成分含量和稳定性。结果表明，超声处理（150 W, 20 min）显著改善了发酵豆浆的质地和稳定性，降低了发酵豆浆的粘度（1918.80 ± 112.33 cP），提高了豆浆的保水能力（97.12%）。此外，超声波处理（150 W, 20 min）也导致发酵豆浆中大豆苷元（17.32 μg/ml）和染料木素（24.48 μg/ml）等活性苷元异黄酮含量增加。利用代谢组学和蛋白质组学建立代谢物的代谢网络，揭示超声处理前后发酵豆浆中主要代谢物质的变化。KEGG分析表明，超声处理发酵豆浆代谢产物的碳水化合物代谢和氨基酸代谢途径明显上调。本研究为豆浆发酵产品的创新、风味延伸和品质提升提供了理论依据。

The application of processing techniques that preserve the nutritional value, quality, and bioactive properties of fermented soymilk without compromising their integrity is of great significance. Ultrasound can promote the decomposition of proteins in soymilk by disrupting their structure, and also has a cell wall-breaking effect on the fermentation strains in soymilk, causing the beneficial components of the bacteria to be released into the soymilk, thereby changing the characteristics and material composition of the fermented soymilk and increasing the content of nutrients and the stability of the soymilk. This study revealed that ultrasonic treatment (150 W, 20 min) significantly improved the texture and stability of <ce:italic>Lactobacillus gasseri</ce:italic> JM1- fermented soymilk, reduced the viscosity of the fermented soymilk (1918.80 ± 112.33 cP), and increased the water-holding capacity of the soymilk (97.12%). Moreover, ultrasonic treatment (150 W, 20 min) also led to an increase in active aglycone isoflavones such as daidzein (17.32 μg/ml) and genistein (24.48 μg/ml) in the fermented soymilk. Metabolomics and proteomics were used to establish a metabolic network of metabolites, revealing the changes in the main metabolic substances in the fermented soymilk before and after ultrasonic treatment.
