A physicochemical characterization was performed on a pennate-type diatomite of lacustrine origin from the southern region of Peru. Diatomite treatments were conducted with the goal of applying this material in adsorption of cadmium, various physical and chemical modifications were carried out, including thermal treatment and modifications with hydrochloric acid, sulfuric acid, and sodium hydroxide. A composite with cellulose and sulfuric acid was also prepared, and finally, a chelating agent EDTA (Ethylenediaminetetraacetic acid) was added. The thermal modifications showed weakly bound hydroxyl groups on the surface, originating from adsorbed water, as well as strongly bound hydroxyl groups from silanol group, as observed in FTIR (Fourier Transform Infrared Spectroscopy) studies. Higher adsorption capacity of cadmium values were obtained in samples modified with 0.5 M NaOH post thermal modification at 700 °C. SEM analysis showed a uniform distribution of cadmium on the diatomite surface. However, modifications with cellulose and sulfuric acid, as well as EDTA, did not significantly increase cadmium adsorption.

对秘鲁南部地区湖相原生的戊酸盐型硅藻土进行了理化表征。对硅藻土进行了处理，目的是将该材料用于吸附镉，并进行了各种物理和化学改性，包括热处理和盐酸、硫酸和氢氧化钠改性。还制备了纤维素与硫酸的复合材料，最后加入螯合剂EDTA（乙二胺四乙酸）。在FTIR（傅里叶变换红外光谱）研究中发现，热修饰表明，表面上有来自吸附水的弱结合羟基，以及来自硅醇基的强结合羟基。在700℃热改性后，用0.5 M NaOH改性的样品获得了较高的镉吸附量。扫描电镜分析表明，镉在硅藻土表面分布均匀。然而，纤维素和硫酸以及EDTA的改性并没有显著增加镉的吸附。

AZ31 magnesium alloy is one of the lightweight metallic engineering materials that are widely used in many industrial areas such as aviation, space, automobile and electronics industries, biomedical applications, where structural weight reduction is at the forefront of design principles. This study focuses on the growth of MgO and MgO:B₅H₁₀NaO₁₃ doped oxide coatings on the surface of AZ31 magnesium alloy by micro arc oxidation (MAO) method in order to improve its usage areas and lifetime in industrial applications, and to investigate the structural, morphological, adhesion and corrosion properties of the grown coatings. In the study, MgO coatings were grown by MAO method and MgO:B₅H₁₀NaO₁₃ doped composite oxide coatings were grown by adding sodium pentaborate (B₅H₁₀NaO₁₃) nanoparticles into the electrolytic solution in MAO method. The phase structure of the grown coatings was determined by X-ray Diffraction (XRD), microstructure by Scanning Electron Microscopy (SEM) and chemical composition by Energy Dispersive X-ray Spectroscopy (EDS). The hardness of MgO and MgO:B₅H₁₀NaO₁₃ doped composite oxide coatings were determined by microhardness tester, the adhesion resistance with the base material was determined by Scratch Tester and the corrosion resistance was determined by potentiodynamic polarization tester. As a result, it was observed that dense and homogeneous coatings were grown on the surfaces of particle-added (MgO:B₅H₁₀NaO₁₃) coatings, that porosity and pore sizes on the surfaces of the coatings were reduced, that microcracks were reduced, and that coatings with high bond strength with the base material were grown. It was also determined that the corrosion resistance of the coatings with particle addition (MgO:B₅H₁₀NaO₁₃) was higher than the corrosion resistance of the coatings without particle addition (MgO).

AZ31镁合金是一种轻量化金属工程材料，广泛应用于航空、航天、汽车、电子、生物医学等诸多工业领域，结构减重是设计原则的前沿。为了提高AZ31镁合金的使用面积和寿命，本研究采用微弧氧化（MAO）方法在AZ31镁合金表面生长MgO和MgO:B5H10NaO13掺杂氧化物涂层，并研究其结构、形貌、附着力和腐蚀性能。本研究采用MAO法生长MgO涂层，采用MAO法在电解溶液中加入五硼酸钠（B5H10NaO13）纳米颗粒生长MgO:B5H10NaO13掺杂复合氧化物涂层。用x射线衍射仪（XRD）、扫描电镜（SEM）和能谱仪（EDS）分别测定了涂层的物相结构、微观结构和化学成分。采用显微硬度计测定了MgO和MgO:B5H10NaO13掺杂复合氧化物涂层的硬度，用划痕仪测定了涂层与基材的粘附性能，用动电位极化仪测定了涂层的耐腐蚀性能。结果表明，添加颗粒（MgO:B5H10NaO13）的涂层表面生长致密均匀，涂层表面孔隙率和孔径减小，微裂纹减少，涂层与基材结合强度高。结果表明，添加颗粒（MgO:B5H10NaO13）的涂层的耐蚀性高于未添加颗粒（MgO）的涂层。

A simple, fast and energy efficient microwave-assisted hydrothermal method was developed for the preparation of nanocrystalline zirconia from commercially available ZrOCl₂·8H₂O and KOH. The synthesis was conducted at 180 °C for 20 min by two ways: direct decomposition of ZrOCl₂·8H₂O (sample Z), and precipitation of ZrOCl₂·8H₂O with KOH and dehydration of hydroxides (sample ZK). The as-synthesized powders were calcined at 500 °C, and all the resulting products were characterized by XRD, FE-SEM, HR-TEM and SAED. Both the as-synthesized and calcined nanoparticles were highly crystalline. A single monoclinic phase was obtained for sample Z, while for sample ZK a tetragonal phase was achieved as the main phase with a minor fraction of monoclinic. The particles of the as-synthesized sample Z showed irregular and semi-hexagonal shapes, although they changed to spherical or ellipsoidal shapes during heat treatment. The particles of the sample ZK, both as-synthesized and calcined, exhibited nearly spherical or ellipsoidal shapes. The average crystallite size for the as-synthesized samples Z and ZK were 3.2 ± 0.8 and 5.5 ± 0.9 nm, respectively, while for the calcined ones the values were 8.5 ± 1.2 and 7.6 ± 1.2 nm, respectively.

以ZrOCl2·8H2O和KOH为原料，建立了一种简单、快速、高效的微波水热法制备纳米氧化锆的方法。在180℃下，通过直接分解ZrOCl2·8H2O（样品Z）和用KOH沉淀ZrOCl2·8H2O并脱水（样品ZK）两种方式合成。将合成的粉末在500℃下煅烧，并用XRD、FE-SEM、HR-TEM和SAED对产物进行了表征。合成的纳米粒子和煅烧的纳米粒子都是高度结晶的。样品Z以单斜相为主，样品ZK以四方相为主，单斜相较少。合成样品Z的颗粒形状呈不规则和半六边形，但在热处理过程中颗粒形状变为球形或椭球形。样品ZK的颗粒，无论是合成的还是煅烧的，都呈现出接近球形或椭球体的形状。合成样品Z和ZK的平均晶粒尺寸分别为3.2±0.8和5.5±0.9 nm，煅烧样品Z和ZK的平均晶粒尺寸分别为8.5±1.2和7.6±1.2 nm。

This work aims to study the interaction of sintered yttria-stabilized zirconia (7YSZ) ceramic under a volcanic ash mix at an engine representative temperature of 1350 °C. In this work, two different locations – distance from Mexico Popocatépetl Volcano were chosen to collect the ashes, and to perform their melting process with variable chemical composition. Afterward, each ash was deposited on the surface of 7YSZ ceramic coupons, then they were exposed at heating and cooling cycles at designed temperature equal to 1350 °C. After 8 cycles of thermal treatment testing of 8 h, the morphology and microstructure analysis of the 7YSZ coupons was carried out using microscopy and X-ray diffraction analysis techniques. The results showed that a molten ash layer, with smooth morphology of size of 60 μm of thick, was formed on the ceramic surface. Based on the observed degradation, the general status of the coupons after 8 cycles of thermal test, presented failure by growth of large cracks which were associated to the infiltration of melted ash through the thickness of ceramic coupon. This melted ash infiltrated trough the fine grain microstructure, promoted the development of a compose rich in silica, which is brittle and therefore promoted cracks initiation with subsequent propagation in the substrate.

本研究旨在研究在1350℃的发动机代表温度下，烧结钇稳定氧化锆（7YSZ）陶瓷在火山灰混合物下的相互作用。在这项工作中，选择了两个不同的地点-距离墨西哥popocat petl火山很远的地方收集灰烬，并以不同的化学成分进行它们的融化过程。然后，将各灰分沉积在7YSZ陶瓷片的表面，然后在1350℃的设计温度下进行加热和冷却循环。经过8次8 h的热处理测试后，利用金相显微镜和x射线衍射分析技术对7YSZ试样进行形貌和显微组织分析。结果表明：在陶瓷表面形成了一层厚度为60 μm的光滑的熔灰层；从观察到的退化情况来看，经过8个循环热试验后，瓷片的总体状态表现为出现较大裂纹，这与熔融灰渗透陶瓷瓷片厚度有关。熔融灰通过细晶组织渗透，促进了富含二氧化硅的组分的发展，这种组分很脆，因此促进了裂纹的萌生和随后在基体中的扩展。

Studies of ceramics and glass from an archaeometric perspective have considerably increased during the last few decades in Ceramic Science and Technology journals. This paper presents a bibliometric study undertaken on 147 archaeometric articles published between 2000 and 2023 in the Q1 high impact journals Boletín de la Sociedad Española de Cerámica y Vidrio (BSECV), Journal of the European Ceramic Society (JECerS) and Journal of the American Ceramic Society (JACerS). The study was carried out with the aim at determining the impact and evolution of Archaeometry in these journals, the characteristics of the materials studied, and the level of interdisciplinarity and interinstitutional collaboration in the archaeometric works published. The main parameters analyzed were: number of archaeometric publications, materials studied, authors, and institutions. Resulting data indicated that journals have experienced an increase in archaeometric works on historical and archeological ceramics and glass, and BSECV is the journal with the highest representation. Spanish universities and other public institutions have a very outstanding representation in all three journals. In recent years, archaeometric approaches have included more authors and institutions from different countries, which evidences a high level of interdisciplinarity and interinstitutional collaboration.

在过去的几十年里，陶瓷科学与技术期刊上从考古角度对陶瓷和玻璃的研究大大增加。本文介绍了一项文献计量学研究，对2000年至2023年间发表在Q1高影响力期刊Boletín de la Sociedad Española de Cerámica y Vidrio （BSECV）、Journal of European Ceramic Society （JECerS）和Journal of American Ceramic Society （JACerS）上的147篇考古论文进行了研究。进行这项研究的目的是确定这些期刊上考古计量学的影响和演变，研究材料的特点，以及发表的考古计量学作品的跨学科和机构间合作水平。分析的主要参数是：考古出版物的数量、研究的材料、作者和机构。结果表明，期刊上关于历史和考古陶瓷和玻璃的考古作品有所增加，BSECV是代表性最高的期刊。西班牙的大学和其他公共机构在这三种期刊上都有非常出色的代表性。近年来，来自不同国家的学者和机构加入了考古研究的行列，显示出高水平的跨学科和机构间合作。

This study compares two different scaffolds (dicalcium silicate – Ca₂SiO₄ – core covered with a glass of composition Ca₂P₆O₁₇ doped with lithium and with strontium) loaded with metronidazole alone and with metronidazole combined with ozone. Complexes metronidazole-2-hydroxypropyl-β-cyclodextrins (HP-β-CDs) were used to increase the solubility and availability of metronidazole. The concentration of metronidazole used was 40.8 mg/mL (58.4 mM), with a molar ratio of 1:1 and 1.5 mL of ozone oil were added to the different scaffolds. The disk diffusion method against the Gram-positive bacterium Staphylococcus aureus and the Gram-negative bacterium Escherichia coli showed microbial inhibition but not statistically significant (p > 0.05) halo inhibition produced by metronidazole alone and that produced by metronidazole combined with ozone.

This research is expected to have strong social impact directly affecting the quality of life of those affected by osteonecrosis as these nanostructures anchored to structures with a porous 3D-core could facilitate bone regeneration promoted by cell adhesion, vascularization and nutrients supply.

本研究比较了两种不同的支架（硅酸二钙- Ca2SiO4 -核心覆盖有掺杂锂和锶的Ca2P6O17组成的玻璃）单独负载甲硝唑和甲硝唑结合臭氧。采用配合物甲硝唑-2-羟丙基-β-环糊精（HP-β-CDs）提高甲硝唑的溶解度和可用性。使用的甲硝唑浓度为40.8 mg/mL (58.4 mM)，摩尔比为1:1，在不同的支架中加入1.5 mL臭氧油。圆盘扩散法对革兰氏阳性菌金黄色葡萄球菌和革兰氏阴性菌大肠杆菌均有抑菌作用，但无统计学意义(p >；单用甲硝唑和与臭氧联用甲硝唑产生的光晕抑制作用（0.05）。这项研究预计将对骨坏死患者的生活质量产生强烈的社会影响，因为这些纳米结构锚定在具有多孔3d核的结构上，可以通过细胞粘附、血管化和营养供应促进骨再生。

Compacted soil walls provide environmental benefits due to their low impact and embodied energy. Although their mechanical strength is lower than other materials, they meet safety requirements. Current trends promote circular economy solutions, such as waste reuse. This study assesses recycled glass in lime- and cement-stabilized rammed earth as a replacement for natural sand to enhance waste management and soil properties. Ultrasonic inspection confirms increased compressive strength and density, especially in cement-stabilized mixtures. Statistical analysis reveals a direct correlation between crushed glass content and improved properties. The optimal replacement rate is 75% for lime and 100% for cement. The superior performance in cement-stabilized samples is due to a pozzolanic reaction absent in lime mixtures. Both binders show significant reductions in thermal conductivity, improving energy efficiency without compromising structural integrity. Ultrasound proves reliable for predicting compressive strength and stiffness, supporting the viability of this approach. The incorporation of recycled glass in compacted soil offers a sustainable construction alternative, balancing environmental benefits with enhanced mechanical and thermal performance.

压实土墙由于其低影响和蕴含的能源而具有环境效益。虽然其机械强度低于其他材料，但满足安全要求。目前的趋势是促进循环经济解决方案，如废物再利用。本研究评估了石灰和水泥稳定夯土中的再生玻璃作为天然砂的替代品，以加强废物管理和土壤特性。超声检查证实抗压强度和密度增加，特别是在水泥稳定混合物中。统计分析表明，碎玻璃含量与性能改善之间存在直接关系。最佳替代率为石灰75%，水泥100%。水泥稳定样品的优越性能是由于石灰混合物中不存在火山灰反应。这两种粘合剂都能显著降低导热性，在不影响结构完整性的情况下提高能源效率。超声被证明是可靠的预测抗压强度和刚度，支持这种方法的可行性。在夯实的土壤中加入回收玻璃提供了一种可持续的建筑替代方案，平衡了环境效益与增强的机械和热性能。

A ventilated facade can be understood as a cladding system fixed to the external wall of the building using mechanical anchor points. The ventilated facade, in addition to its aesthetic effect, improves the thermal (thermal comfort), acoustic and energy efficiency performance of the building. The ventilated facade (or facade) system (VFS) is a construction alternative using non-adhered industrialised elements. Its use has increased substantially in recent years and it has been chosen by architects as a suitable solution for retrofitting existing buildings and for buildings to be built. It is an envelope solution that is suitable for a variety of building types, climates and design configurations. The influence of VFS on the thermal, energy and acoustic performance of buildings is a current topic of research and can be characterised as a sustainable solution in the construction industry. The aim of this article is to present the state of the art of current literature on the application of VFS technologies, in terms of thermal, energy and acoustic analysis, the performance of different coatings applied, fixing systems and the advantages and disadvantages of the system, in order to provide guidelines for future studies and projects.

Environmentally friendly (Ba,Ca)(Zr,Ti)O₃ ceramics (BCZT) are being investigated as a viable alternative to the leading commercially used lead titanate–zirconate ceramics. These ferro-piezoelectric ceramics exhibit fascinating properties for a range of applications, dependent on several multiscale characteristics, including composition, crystal structure, domain structure, ceramic microstructure and bulk issues. To provide reproducible quality, a thorough grasp of processing control is essential. This review begins with a historical overview of BCZT ceramic development, followed by a phase diagram examination. The morphotropic phase boundary is explored, detailing the intrinsic and extrinsic contributions to the system's piezoelectricity, as well as the critical aspects to consider while processing. The factors to contemplate for an industrially scalable solid state processing pathway are reviewed, with a focus on mechanical activation. Additionally, the milling processes utilized for BCZT synthesis and sintering, as well as water-based sustainable processing, are analysed. The assessment concludes with the promise of emerging uses in biotechnology for medical purposes.
