The chosen plan for our case study is a network mixture design consisting of 21 mixtures. The application of this method has proven to be immensely useful in studying the influence of composition parameters (composite design) and the utilization of various types of mineral additives (mixture design). The application of the Design of Experiments (DOE) method, based on a statistical approach, allowed for a better understanding of the effect of formulation parameters, including the proportion of alluvial sand (75%), dune sand (25%), the total amount of sand kept at constant percentages, the dosages of brick powder, limestone filler and ceramic powder (all varying from 0 %, 20 %, 40 %, 60 %, 80 %, and 100 %), while keeping the dosage of superplasticizer and the water/binder ratio constant. This approach helped to understand the interactions between these parameters and their impact on the process. Mathematical models relating the variations of these parameters to the workability and compressive strength of such concrete mixtures have been established. The results obtained show that the workability of SCSC (expressed by slump flow and V-funnel flow) improves with the increase in the dosage of limestone filler (FC), brick powder (PB), and ceramic powder (PC), with element having a different impact, be it alone or in a combination. Moreover, they all improved the behavior of SCSC in both the fresh and hardened states. The experiment shows that increasing the proportions of FC and PC in the mixture, whether linear, binary, or ternary, leads to a significant improvement in compressive strength. Furthermore, better strength is observed in the ternary mixture at 28 days, with a strength of 43 MPa, with the following proportions (FC 70%, PB 20%, PC 10%). Finally, the result at 180 days of 48 MPa confirms the following proportions (PC 60 %, FC 30 %, PB 10 %) The compliance of some SCSC compositions was tested according to the recommendations of the French Association of Civil Engineering.
我们的案例研究选择的方案是由 21 种混合物组成的网络混合物设计。事实证明,这种方法在研究成分参数的影响(复合设计)和各类矿物添加剂的使用(混合物设计)方面非常有用。以统计方法为基础的实验设计(DOE)方法的应用有助于更好地了解配方参数的影响,包括冲积砂(75%)、沙丘砂(25%)的比例,保持恒定百分比的砂总量,砖粉、石灰石填料和陶瓷粉的用量(均为 0%、20%、40%、60%、80% 和 100%),同时保持超塑化剂用量和水/粘合剂比率不变。这种方法有助于了解这些参数之间的相互作用及其对工艺的影响。这些参数的变化与此类混凝土混合物的工作性和抗压强度之间的关系数学模型已经建立。研究结果表明,随着石灰石填料(FC)、砖粉(PB)和陶瓷粉(PC)用量的增加,SCSC 的工作性(以坍落度流动和 V 型漏斗流动表示)得到改善。此外,它们都能改善 SCSC 在新鲜和硬化状态下的性能。实验表明,增加 FC 和 PC 在混合物中的比例,无论是线性、二元还是三元,都能显著提高抗压强度。此外,三元混合物在 28 天时的强度更高,达到 43 兆帕,其比例如下(FC 70%、PB 20%、PC 10%)。最后,180 天后 48 兆帕的结果证实了以下比例(PC 60%、FC 30%、PB 10%)。 根据法国土木工程协会的建议,对一些 SCSC 成分的符合性进行了测试。

The main objective of this paper research is a comparative study on the effect of the glass powder (GP) substitute from collected and recycled glass waste, as a fine partial cement replacement on the mechanical performance and durability of high performance concrete (HPC) and ordinary concrete (OC). For this two cement dosing were used of 400 kg/m3 to formulate OC and 450 kg/m3 to formulate HPC, and GP as considered binder like cement and not as fine addition, hence binder represent the sum of cement with GP (L=C+GP) with which will be made our two concretes formulation. Two ratios were used for the Water/Binder (W/B), the first W/B=0.35 for the HPC and the second W/B=0.5 for the OC, this ration is very important to fix the concentration of superplasticizer. A percentage of 10% and 20% substitution of cement CPA without additions noted CEM I 52.5 by the glass powder with fineness of 3600 cm 2/g are used. The evaluation of the compressive strength was followed from 7 to 365 days in order to study the behavior of the GP at different ages affected by the cement dosing and the ratio W/B compared to the reference concrete without GP for the two concretes HPC and OC. At 28 days the strengths of concretes with GP is affected by the replacement of a quantity of cement since the two reference concretes were superior but beyond this age an inverse behavior is noticed such that results obtained at age of 365 days seem to be advantageous in terms of savings in the quantity of cement used by interpreting the compressive strength, and the decrease in quantity of water in the mixtures offers a remarkable difference between the two concretes studied by using 20 % of GP as replacement of cement.
本文研究的主要目的是比较研究从收集和回收的玻璃废料中提取的玻璃粉(GP)替代品作为部分细水泥替代品对高性能混凝土(HPC)和普通混凝土(OC)机械性能和耐久性的影响。因此,粘合剂代表水泥与 GP 的总和(L=C+GP)。水/粘合剂(W/B)采用了两种比例,第一种 W/B=0.35 用于 HPC,第二种 W/B=0.5 用于 OC,这一比例对于确定超塑化剂的浓度非常重要。使用细度为 3600 cm 2/g 的玻璃粉分别替代 10%和 20%的水泥 CPA(未添加 CEM I 52.5)。抗压强度的评估从 7 天持续到 365 天,目的是研究不同龄期的 GP 受水泥剂量和 W/B 比率影响的行为,并与 HPC 和 OC 两种不含 GP 的参考混凝土进行比较。在 28 天时,添加了 GP 的混凝土的强度会受到一定量水泥替代物的影响,因为两种参考混凝土的强度都较高,但在超过这个龄期后,就会出现反向行为,因此在 365 天龄期获得的结果在通过解释抗压强度来节省水泥用量方面似乎更有优势,而且通过使用 20% 的 GP 作为水泥替代物来减少混合物中的水量,在所研究的两种混凝土之间产生了显著的差异。

The crude distillation unit is the most critical elements in the refining process. Moreover, most of the equipment in the distillation unit are made of general carbon steels. Data analysis models, machine learning techniques can predict corrosion degradation rates. We used Pearson’s correlation coefficient and multiple linear regression, to predict the impact of process parameters. Altogether, we have analysed 84 channels of technological parameters, and 22 different types of crude oils. Among the corrosion agents, the chloride content strongly affected the weight loss of coupons, where the highest coefficient was 0.68. The most influential parameter is found to be the pH value. Thus, an estimation method of the pH value is set up to predict the corrosion degradation rate. The regression correlation for estimating the pH value is 0.53 if the corrosion agents are not used, which can be improved to 0.76 if the corrosion agents are also used in the regression analysis.
原油蒸馏装置是炼油过程中最关键的部分。此外,蒸馏装置中的大部分设备都由普通碳钢制成。数据分析模型、机器学习技术可以预测腐蚀降解率。我们使用皮尔逊相关系数和多元线性回归来预测工艺参数的影响。我们总共分析了 84 种工艺参数和 22 种不同类型的原油。在腐蚀剂中,氯化物含量对试样的重量损失影响很大,最高系数为 0.68。影响最大的参数是 pH 值。因此,建立了一种 pH 值估算方法来预测腐蚀降解率。如果不使用腐蚀剂,估计 pH 值的回归相关系数为 0.53,如果在回归分析中也使用腐蚀剂,则相关系数可提高到 0.76。

Aluminum-doped zinc oxide (AZO) films have emerged as promising transparent electrodes for various optoelectronic applications due to their superior transparency, electrical conductivity, and cost-effectiveness compared to indium tin oxide (ITO). Despite their widespread use, investigations into the electromechanical properties of AZO films, especially under various mechanical deformations, remain limited. This study employs RF magnetron sputtering to deposit AZO films on polyethylene naphthalate (PEN) substrates and explores their mechanical behavior through uniaxial tensile fragmentation and bending tests, coupled with in-situ optical microscopy. Changes in electrical resistance of AZO films were monitored in situ during deformation. Fatigue behavior was examined to further understand mechanical failure, and SEM was used for surface characterization. A critical strain of about 3.1 percent was detected during uniaxial tensile testing, marking the onset of cracks in AZO-coated PEN. In contrast to thicker films, thinner films demonstrated improved stretchability beyond the initiation of crack onset strain. Tension and compression bending tests revealed that the material has excellent bendability, as shown by its critical radii of 5.4 mm and 3.9 mm, respectively. The bending reliability of AZO films under compression was found to be superior than that under tension. Bending fatigue experiments demonstrated that AZO films could withstand cyclic stress without experiencing no ticeable cracks after 100 cycles and with very minor resistance change. This study contributes to the creation of more reliable and optimized flexible optoelectronic devices by giving substantial quantitative data on the performance of AZO films when exposed to mechanical stress.
与氧化铟锡(ITO)相比,掺铝氧化锌(AZO)薄膜具有更高的透明度、导电性和成本效益,因此已成为各种光电应用中颇具前景的透明电极。尽管 AZO 薄膜被广泛使用,但对其机电特性,尤其是在各种机械变形条件下的机电特性的研究仍然有限。本研究采用射频磁控溅射技术在聚萘二甲酸乙二醇酯(PEN)基底上沉积 AZO 薄膜,并通过单轴拉伸破碎和弯曲测试以及原位光学显微镜来探索其机械行为。在变形过程中,对 AZO 薄膜的电阻变化进行了原位监测。对疲劳行为进行了研究,以进一步了解机械故障,并使用扫描电镜进行表面表征。在单轴拉伸测试中检测到了约 3.1% 的临界应变,这标志着 AZO 涂层 PEN 开始出现裂纹。与较厚的薄膜相比,较薄的薄膜在出现裂纹应变后的拉伸性有所改善。拉伸和压缩弯曲测试表明,这种材料具有出色的弯曲性,其临界半径分别为 5.4 毫米和 3.9 毫米。研究发现,AZO 薄膜在压缩条件下的弯曲可靠性优于在拉伸条件下的弯曲可靠性。弯曲疲劳实验表明,AZO 薄膜可以承受循环应力,在 100 次循环后不会出现可察觉的裂纹,阻力变化非常小。这项研究提供了有关 AZO 薄膜在机械应力作用下性能的大量定量数据,有助于制造更可靠、更优化的柔性光电器件。

Aluminium nitride thin films were fabricated using pulsed laser deposition and DC magnetron sputtering. Different technological parameters and the effects of different substrates on the optical and structural parameters of AlN samples were studied. An X-ray diffraction study was performed for the layer deposited on the Si3N4 substrate. A high-energy electron diffraction study was also carried out for the layer deposited on a KCl substrate. Transmission spectra of layers on quartz, sapphire, and glass substrates were obtained. An evaluation of the optical band gap of the obtained layers was carried out (Eg form 3.81 to 5.81 eV) and the refractive index was calculated (2.58). The relative density of the film (N1TN-AlN sample) is 1.26 and was calculated using the Lorentz-Lorentz relationship. Layers of aluminium nitride show an amorphous character with a polycrystalline region. It was shown that the properties of AlN films strongly depend on the method, growth conditions, and substrate used.

The technological parameters of 3D printing have an influence on the mechanical properties of the manufactured components. The purpose of the article was to study the comparative influence of the technological parameter of the number of shells variable in two stages (2 and 10) on selected mechanical properties. The maximum tensile stress for the number of shells 10 was 39.80 MPa, which is higher compared to the number of shells 2: 30.98 MPa. In the case of the maximum bending stress for the number of shells 10, an average value of 61.02 MPa was obtained, which is higher compared to the number of shells of 2: 37.46 MPa. Furthermore strong fit of the Kelvin-Voight model was obtained, as confirmed by the values of the Cℎi 2: 0.0001 and R 2: 0.997 coefficients.

Nanocomposites of Nanocarbon Functionalized Carbon Fibers—Manufacturing to Methodological Applications 纳米碳功能化碳纤维纳米复合材料--从制造到方法应用

Carbon fibers have been technically applied in high performance materials and industrial scale applications. Importantly, carbon fiber reinforced composite materials have found applications in aerospace industries. These properties of carbon fiber reinforced composites depend upon the carbon fiber features such as length, orientation, surface properties, adhesion with matrices, etc. To improve the surface properties of carbon fibers and adhesion and interactions with polymers, fiber modification has been suggested as an efficient approach. Carbon nanoparticle or nanocarbon functionalized carbon fibers have been manufactured using various facile physical and chemical approaches such as electrospraying, electrophoretic deposition, chemical vapor deposition, etc. Consequently, the modified carbon fibers have nanocarbon nanoparticles such as graphene, carbon nanotube, nanodiamond, fullerene, and other nanocarbons deposited on the fiber surface. These nanocarbon nanoparticles have fine capability to improve interfacial linking of carbon fibers with the polymer matrices.

碳纤维已在技术上应用于高性能材料和工业领域。重要的是,碳纤维增强复合材料已在航空航天工业中得到应用。碳纤维增强复合材料的这些特性取决于碳纤维的特征,如长度、取向、表面特性、与基体的粘附性等。为了改善碳纤维的表面特性以及与聚合物的粘附性和相互作用,纤维改性被认为是一种有效的方法。碳纳米粒子或纳米碳功能化碳纤维的制造采用了各种简便的物理和化学方法,如电喷雾、电泳沉积、化学气相沉积等。因此,改性碳纤维表面沉积了石墨烯、碳纳米管、纳米金刚石、富勒烯等纳米碳纳米粒子。这些纳米碳纳米粒子具有改善碳纤维与聚合物基质界面连接的优良性能。在碳纤维上均匀沉积纳米碳时采用了化学气相沉积法,涉及物理或化学改性的化学方法也经常使用。由此产生的先进环氧树脂/碳纤维/纳米碳复合材料显示出更好的拉伸和物理特性。本综述主要针对聚合物/纤维/纳米填料纳米复合材料的制造和技术方面,旨在开发高性能结构。纳米碳功能化碳纤维的形态、强度、模量、韧性、热稳定性和其他物理特性都得到了改善。此外,制备的聚合物/纤维/纳米填料纳米复合材料具有良好的界面粘附性、基体-纳米填料-填料相容性和其他特性。这些纳米材料的应用领域非常广泛,包括强化工程结构、超级电容器、形状记忆材料等。

Importantly, carbon fiber reinforced composite materials have found applications in aerospace industries. These properties of carbon fiber reinforced composites depend upon the carbon fiber features such as length, orientation, surface properties, adhesion with matrices, etc. To improve the surface properties of carbon fibers and adhesion and interactions with polymers, fiber modification has been suggested as an efficient approach. Carbon nanoparticle or nanocarbon functionalized carbon fibers have been manufactured using various facile physical and chemical approaches such as electrospraying, electrophoretic deposition, chemical vapor deposition, etc. Consequently, the modified carbon fibers have nanocarbon nanoparticles such as graphene, carbon nanotube, nanodiamond, fullerene, and other nanocarbons deposited on the fiber surface. These nanocarbon nanoparticles have fine capability to improve interfacial linking of carbon fibers with the polymer matrices. The chemical vapor deposition has been adopted for uniform deposition of nanocarbon on carbon fibers and chemical methods involving physical or chemical modification have also been frequently used. The resulting advanced epoxy/carbon fiber/nanocarbon composites revealed improved tensile and physical profiles.
