Resumen

The Materials Research Center at Northwestern University is an interdisciplinary center that supports theoretical and applied research on experimental advanced materials. Conceived during the post-Sputnik era, it is now in its 26th year.The Center, housed in the university's Technological Institute, was one of the first three centers funded at selected universities by the federal government in 1960. The federal government, through the National Science Foundation, now supplies $2.4 million annually toward the Center's budget, and Northwestern University supplements this amount. Approximately one third of the money is used for a central pool of essential equipment, and the other two thirds is granted to professors for direct support of their research. Large amounts of time on supercomputers are also awarded to the Materials Research Center from the National Science Foundation and other sources.The Center's role enables it to provide partial support for Northwestern University faculty working at the frontiers of materials research and to purchase expensive, sophisticated equipment. All members of the Center are Northwestern University investigators in the departments of materials science and engineering, chemical engineering, electrical engineering, chemistry, or physics. The Materials Research Center is a major agent in fostering cross-departmental research efforts, thereby assuring that materials research at Northwestern University includes carefully chosen groups of faculty in physics, chemistry, and various engineering departments.

Resumen

Most great technological advances initially required finding a solution to materials problems, a fact that is not very often recognized. The development of nuclear energy is no exception to this rule. The fuel in the reactor core, cladding of the fuel, and structures which support the core or which carry the coolant are, indeed, subjected to extreme conditions of radiation flux, temperature, pressure, and corrosion. In order to achieve safe, industrial reactors, the French Atomic Energy Commission (CEA) had to build an enormous program in materials research and development from the ground floor. At present, CEA has reached a very high level of knowledge and expertise through excellent scientific teams and exceptional equipment.In its present industrial phase, the French Nuclear Program still requires considerable effort in research, but it does enable the nation's industry to take advantage of the CEA's materials capabilities. In accordance with its mission to facilitate the utilization of research results, the CEA launched research and development programs in different non-nuclear industries where its research could find new applications.Since its creation in 1955, the Grenoble Nuclear Research Center (CEN-G), one of the five civilian centers of the CEA, has concentrated a great part of its research on basic (solid-state physics) and applied aspects (nuclear metallurgy). This double orientation, in which basic research is used as a basis for applied research, is an original feature of the CEN-G.

Resumen

The basic task of the logistics distribution center is to achieve the storage and distribution of materials, and to plan, implement, and manage the effective flow of materials from the supplying place to the consumption place. Scientific location of logistics distribution center can effectively reduce logistics cost, improve the speed of circulation, increase the profits of enterprises, and enhance the core competitiveness of enterprises. Combining the advantages of K-means clustering algorithm, this paper applies it to the location problem of logistics distribution center and proposes a logistics distribution center location method combining K-means clustering theory and D-S reasoning, which provides a better solution for the location problem of logistics distribution center. Through case analysis, K-means clustering algorithm can obtain reasonable location of logistics distribution center, which can be applied to the location of multilevel logistics distribution network, and has certain practical application value.

Resumen

Nondestructive evaluation has historically been used almost exclusively for detecting macroscopic defects after materials have been made or put into service. However, the role of NDE is now changing to include in-process control in an effort to increase yields and performance of materials. This includes materials stability during transport, storage, and fabrication, as well as degradation behavior during in-service life. The NDE community has implied that applying NDE in these ways is crucial to solving the economic problems of U.S. manufacturing industries. So called “intelligent manufacturing” is impossible without integrating modern NDE techniques into the production of today's advanced materials.The Johns Hopkins University Center for Nondestructive Evaluation (CNDE) was established in 1984 as an interdisciplinary center for research and instruction, drawing on the resources and talent of the School of Engineering, Applied Physics Laboratory, School of Medicine, and School of Arts and Sciences. Currently 31 faculty or senior staff work with the Center. The techniques being developed are aimed at reliable in-process control of materials and processes. Another important purpose is the education of talented students who will enter the NDE field; 150 students are associated with the Center, a third of whom are graduate students. The CNDE also provides both research collaborators and industrial sponsors with access to all NDE research and instruction at Johns Hopkins University. Twenty-six research institutions have formal cooperative research programs and 19 organizations are corporate sponsors (see Figure 1).

Resumen

The AA 7150-T351, in the form of 40 mm thick plates, was subjected to single-stage aging leading to peak aged condition, and two selected multi-artificial aging treatments leading to the over aged conditions. The microstructural differences along the thickness direction of the AA 7150-T351 plate were investigated using OM and electron backscatter diffraction (EBSD) technique, and the microstructural characterization was studied at different stages of multi-artificial ageing process by transmission electron microscopy. Tensile properties and electrical conductivity measurements were used to evaluate the property homogeneity along the thickness direction of the plate under various artificial aging tempers. It was revealed that the microstructural features and tensile property are inhomogeneous in different layers along the thickness direction, and both grain structure and tensile property exhibit appreciable anisotropy at the same thickness layer. The volume fraction of recrystallized grain of T351 plate in the near surface layer is higher than that in the center layer remarkably. It is also shown that two selected multi-artificial aging tempers can provide optimal precipitates in matrix and at grain boundaries, which gives rise to a combination of high strength and stress corrosion cracking (SCC) resistance in such materials.

Resumen

In this chapter, a vertical information sharing in terms of inventory replenishment / requirement from the customer(s)? retailer(s)? producer? supplier(s) has been done. The constant imprecise fuzzy demands of the goods are made to the retailers by the customers. These goods are produced (along with defectiveness, which decreases due to learning effects) from the raw materials in the producer's production center with a constant production rate (to be determined). Producer stores these raw materials in a warehouse by purchasing these from a supplier and the suppliers collect these raw materials from open markets at a constant collection rate (to be determined). The whole system is considered in a finite time horizon with fuzzy demand for finished products and fuzzy inventory costs. Here shortages are allowed and fully backlogged. The fuzzy chance constraints on the available space of the producer and transportation costs for both producer, retailers are defuzzified using necessity approach. Results indicate the efficiency of proposed approach in performance measurement. This paper attempts to provide the reader a complete picture of supply chain management through a systematic literature review.

Resumen

Aryl amines have received significant interest because these compounds widely exist in the structural backbones of ligands, pharmaceuticals, agrochemicals, natural products, and functional materials. In N-arylation reactions, several types of organic electrophile coupling partners such as (pseudo)halides (Ullmann-type and Buchwald–Hartwig couplings) and boronic acids (Chan–Lam coupling) are popular. The main synthetic methods for the preparation of these compounds involving N-arylation utilize aryl halides. Progress has been made with the coupling of arylating reagents which are less expensive than aryl halides, providing both a cost-effective and more efficient reaction route. For example, the process of C–H bond activation/functionalization, a step-efficient and atom-economical transformation, has emerged as a powerful strategy in C–N bond-forming reactions. Moreover, a transition-metal-free method for the N-arylation of amines using an aryne intermediate has been developed. This chapter focuses on recent advances in chemo- and regioselective N-arylation (either on one N-center or on the exocyclic N-site of the ring) or the selective arylation of amino alcohols without additional protection/deprotection using arylating reagents. This chapter provides an overview of arylating reagents for N-arylation reactions found in both basic and applied chemical research. The substrate scope, limitations, reaction mechanism, and chemoselectivity, as well as related control strategies of these reactions, are discussed. To the best of our knowledge, there has been no book about introducing arylating reagents to develop more efficient and environmentally friendly cross-coupling methods for the N-arylation of amines. We believe this critical review will provide necessary background information on the N-arylation of amines.

Resumen

A realization of intelligent logistic system for a recycling center requires utilization of very latest information and communication technologies. Therefore, versatile technology framework and adapting data-driven solutions to optimize collection, transportation, and processing of recyclable materials is needed. The key components in building the technology framework for enabling intelligent, intelligent logistic recycling service are robust communication platform, reliable vehicle and asset tracking system and AI (Artificial Intelligent) enabled data analysis and management platform. The communication platform facilitates collaboration between stakeholders including recycling company, transportation company, waste management company and local government. Its purpose is to improve information flow and coordination between stakeholders. The vehicle and asset tracking system provides means to monitor and manage various assets and fleet of vehicles operating in the recycling area, which can be fully autonomous or driven by professional drivers. The data provided by the vehicle and asset tracking system must be acquired, analyzed and used for decision making efficiently in real time. The data analysis and management platform store all the data needed for operating intelligent logistic service of a recycling center. It utilizes existing IoT (Internet of Things) technologies and the communication platform. AI solutions are used for analyzing the collected data for further use to provide services for the users of the system. The research question is to how to design Hybrid Intelligent (HI) logistic system for recycling center in MORE industrial park that enables 24/7 autonomous recycling service for companies? The recycling center’s autonomous service is aimed for companies that have need to store larger quantities of various materials for recycling and further use in future. The key requirements from a client’s point of view are 24/7 access to recycling area, safe and secure material storage facility and efficient operations in recycling area. Safety, security and reliability of services in recycling center are particularly important when the center’s operating personnel are not present and available. This is also primary concern for the recycling center operator. The asset and vehicle tracking system must monitor and manage all vehicles in the recycling area regardless who is driving it, human or AI. Therefore, the system must consider human input and learn to manage autonomous traffic to provide support for human activities in the recycling area. The paper proposes a design solution for a smart autonomous recycling service that utilize HI logistic system.

Resumen

In Portugal, it´sa National Strategy, the innovation in teaching, the connection between Faculties and Research Center, being a social and academic responsibility, to the good training and qualification of students. This can be an extra motivating factor for the students performance of academic work and better preparation for working life.In March 2005, the Portuguese government launched the strategy plan for the creation of a Digital Portugal, which is based on three pillars, I: digital inclusion of people, II: Digital transformation of the business fabric and III: digitization of the state. According to this plan, Education and its digitization are part of the 1st pillar, which aims above all “The empowerment and digital inclusion of people emerge as imperatives to respond to the impact that digitization can have on the life of each individual, implying an integrated approach that ensures differentiated measures depending on the life cycle of citizens” (Portugal Digital, p.15), however, in 2020, when the pandemic began, several failures were verified in the digitalization of education, leaving students without conditions / without classes, being urgent for the development and training of students, tools to support the development of their work, however, Little has been done since then.In such a specific area as materials and technologies, the need to find support becomes even more urgent.The new materials and the technological systems, the evaluation of the programmatic contents, increasing the attention to teaching materials in design, offered by the Faculties of design, is an activity in constant update, forcing a better preparation of the contents taught in 1st cycle studies. This is proved by the actual situation promote by the pandemic of COVID19.

Resumen

Recent improvements in technology has enabled the use of very sophisticated sensors such as embedded fiber bragg gratings (FBGs) to obtain strain measurements from a variety of structural types. Conventional strain gauges tend to be heavy and bulky. Because of their accuracy, light weight, small size and flexibility these fiber optic sensors have big potential to be used in space exploration and the aerospace industry especially for flying aircraft that have strict weight and size limitations. These strain measurements can be used to predict the deformation shape of aircraft during real-time flights. The development of such methods for monitoring and control can potentially reduce the risk of in-flight breakups, such as that of the Helios Wing. The Structures, Propulsion, And Control Engineering (SPACE) NASA sponsored University Research Center (URC) of excellence has concentrated in the development of small, lightweight Uninhabited Air Vehicles (UAVs) that have excelled in the area of endurance. Today, the UAV project is focused on the design of a multi-mission multipurpose air system that can operate autonomously. The configuration is a twin boom, pusher, and conventional wing design. In this paper, methods developed by the National Aeronautic and Space Administration (NASA)’s Dryden Flight Research Center for real-time deformation shape prediction of lightweight unmanned flying aerospace structures for the purposes of Structural Health Monitoring (SHM) and condition assessment are investigated. SHM may allow for useful monitoring that would prevent such an event by providing wing shape information and structural monitoring to either a pilot or the flight system, allowing for evasive maneuvers before the breakup would occur. These methods also have the potential for increasing safety, allowing monitoring of structural integrity, detecting damages, and providing real-time flight control feedback. These methods are applied to the SPACE Center UAV for the purpose of assessing the effectiveness of the method and the potential for both SHM and control applications. In this paper, a computational finite element model of the SPACE Center UAV is developed and used to examine the method.

Resumen

Abstract Coke drums are critical units in the delayed coking process to produce lightweight oil products from heavy residual oil. The fulfillment of the designed coke drum lifetime is often obstructed by low-cycle fatigue damage over cyclic thermal and mechanical loading. Considering the tremendous cost of drum replacement and production loss due to shutdown, the coke drum lifetime extension is of great economic significance in the oil and gas industry. A research project regarding coke drum fabrication and repair was initiated in the Manufacturing & Materials Joining Innovation Center (MA2JIC) at the Ohio State University in 2016. The project includes two phases of work. The first phase of the study (2016∼2019) focused on the external weld repair of coke drum materials, while the ongoing second phase of the study (2019∼2023) addressed coke drum fabrication and repair. A novel low-cycle fatigue testing approach was developed using Gleeble thermo-mechanical simulator and was applied to evaluating the performance of coke drum base materials and welded joints under cyclic deformation. The project goal is to improve the fundamental understanding of materials and joint performance that allows the optimization of coke drum design, fabrication, and repair. In this technical paper, the key methodologies and achievements of the project will be introduced, and some future work will be proposed for the next step.

Resumen

The main goal of this study is the optimization of vibration reduction on helicopter blade by using macro fiber composite (MFC) actuator under pressure loading. Due to unsteady aerodynamic conditions, vibration occurs mainly on the rotor blade during forward flight and hover. High level of vibration effects fatigue life of components, flight envelope, pleasant for passengers and crew. In this study, the vibration reduction phenomenon on helicopter blade is investigated. 3D helicopter blade model is used to perform the aeroelastic behavior of a helicopter blade. Blade design is created by Spaceclaim and finite element analysis is conducted by ANSYS 19.0. Generated model are solved via Fluent by using two-way fluid-solid coupling analysis, then the analyzed results (all aerodynamic loads) are directly transferred to the structural model. Mechanical results (displacement etc.) are also handed over to the Fluent analysis by helping fluid-structure interaction interface. Modal and harmonic analysis are performed after FSI analysis. Shark 120 unmanned helicopter blade model is used with NACA 23012 airfoil. The baseline of the blade structure consists of D spar made of unidirectional Glass Fiber Reinforced Polymer +45°/−45° GFRP skin. MFC, which was developed by NASA’s Langley Research Center for the shaping of aerospace structures, is applied on both upper and lower surfaces of the blade to reduce the amplitude in the twist mode resonant frequency. D33 effect is important for elongation and to observe twist motion. To foresee the behavior of the MFC, thermo-elasticity analogy approach is applied to the model. Therefore, piezoelectric voltage actuation is applied as a temperature change on ANSYS. The thermal analogy is validated by using static behavior of cantilever beam with distributed induced strain actuators. Results for cantilever beam are compared to experimental results and ADINA code results existing in the literature. The effects of fiber orientation of MFC actuator and applied voltage on vibration reduction on helicopter blade are represented. The study shows that torsion mode determines the optimum placement of actuators. Fiber orientation of the MFC has few and limited influences on results. Additionally, the voltage applied on MFC has strong effects on the results and they must be selected according to applied model.

Resumen

Application of engineered ceramic materials in high temperature environments of advanced propulsion systems in high performance aircraft; structural demands in ceramic-composite armor; application of high density polyethylene in piping, and reinforced rubber in nuclear power service; and fiber reinforced resin overwraps for piping, all present demanding nondestructive testing challenges. A new technology, Evisive Scan™, has been recently developed that allows condition monitoring in these challenging materials. The internationally patented Evisive Scan™ method is based on microwave interferometry. It utilizes microwaves to interrogate dielectric materials, including material with complex internal structure. The microwaves are reflected at areas of changing dielectric constant. The reflected energy and the interrogating beam are combined to form an interference pattern which is measured in the transceiver as a signal voltage. The method requires access to only one surface, does not require contact or a coupling medium. The signal voltage is sampled at many positions in the inspection area. This point cloud is displayed as an Evisive Scan™ image, which presents volumetric detail of the inspected part. This data is rich with information which is processed in near real time for advanced analysis. The technology has been successfully applied to Ceramic Matrix Composites where it is used to measure density and porosity and identify manufacturing defects. The technology has been demonstrated to be applicable to ceramic composite armor made of monolithic ceramic tiles in complex, multilayer, dielectric structures. The technology is being used to detect manufacturing defects in composite resin structures. The technology has been successfully demonstrated on fiber reinforced resin pipe overwraps, and the technology has been used for condition monitoring of reinforced rubber flexible couplings in nuclear power plants. The nuclear power plant application is performed under a fully qualified, US nuclear quality assurance 10CFR50 App B and NQA-1 compliant program. Examples of these applications are presented, with explanation of the operating principles of the technology and illustrations of the individual applications. Work included in the report is supported by the US Air Force Research Laboratory, US Army Tank-Automotive Research, Development and Engineering Center (TARDEC), US Army Research Laboratory and US Air Force Research Laboratory. Evisive would like to acknowledge project participation and support by Argonne National Laboratory, and Saudi Aramco.

Resumen

While the thermoelectric effects have been known for over 100 years, their traditionally low conversion efficiency for power generation has limited their use to highly specialized applications. With the rapid advancement of thermoelectric materials in recent years, their inherent reliability and power density is being augmented by improvements in efficiency. Recent increases in the figure of merit of materials suitable for operation around 500 °C make them candidates for waste heat recovery, as well as primary power using combustion heaters. The characteristic scalability of thermoelectric generators makes them best suited for low power applications where alternative generators become impractical. However, with the development of thermoelectric device technology in parallel with materials advancements, it may become viable to design thermoelectric generators for auxiliary power in automotive applications. The research presented here represents the initial stages of the development of a thermoelectric power unit (TEPU). While thermoelectric generator technology can be applied to any fuel, this research targets the use of diesel fuel which is readily available for both military and consumer applications and is more easily and safely transported than many alternatives. The use of diesel fuel for a TEPU is enabled by the use of an atomizer technology developed at The Ohio State University Center for Automotive Research. A baseline prototype incorporating this novel diesel fuel atomizer/combustor with conventional thermoelectric materials and heat exchange designs has been constructed and tested. Preliminary data highlights the viability of diesel fuel for thermoelectric power generation as well as the areas which demand further development. This prototype will serve as the baseline for evaluating future designs incorporating advanced materials and novel system designs.
