Design and Operation Mode of Zigzag Air Classifier
The zigzag (ZZ) classifier is a sorting and classification device with a wide range of applications (e.g. recycling, food industry). Due to the possible variation of geometry and process settings, the apparatus is used for various windows of operation due to the specifications of the separation (e.g. cut sizes from 100 µm to several decimetres, compact and fluffy materials as well as foils).

Sustainable Manufacturability of Archimedes Screw Turbines
Archimedes screw turbines are considered a new technology in small- or microscale hydropower. The Archimedes screw turbines is a hydroturbine that is geometrically modeled after Archimedean screws, which are machines historically used to pump water to higher elevations. Archimedes screw turbines are easy and practical to operate compared with other turbines. It is considered a fish-friendly turbine due to the geometric structure of the screw-shaped turbine that allows fish to swim in between them.

Silicon Micro-Strip Detectors
Silicon micro-strip detectors are fundamental tools for the high energy physics. Each detector is formed by a large set of parallel narrow strips of special surface treatments (diode junctions) on a slab of very high quality silicon crystals. Their development and use required a large amount of work and research. A very synthetic view is given of these important components and of their applications. Some details are devoted to the basic subject of the track reconstruction in silicon strip trackers. Recent demonstrations substantially modified the usual understanding of this argument.

Machine Learning for Additive Manufacturing
Additive manufacturing (AM) is the name given to a family of manufacturing processes where materials are joined to make parts from 3D modelling data, generally in a layer-upon-layer manner. AM is rapidly increasing in industrial adoption for the manufacture of end-use parts, which is therefore pushing for the maturation of design, process, and production techniques. Machine learning (ML) is a branch of artificial intelligence concerned with training programs to self-improve and has applications in a wide range of areas, such as computer vision, prediction, and information retrieval. Many of the problems facing AM can be categorised into one or more of these application areas. Studies have shown ML techniques to be effective in improving AM design, process, and production but there are limited industrial case studies to support further development of these techniques.

Technologies for Soft Robotics Grippers
Robotics grippers are one of the most important components in the industry because of their capability to manipulate objects. They not only realize transportation tasks but also perform quality control to optimize robotic work cells. Thanks to the advance in soft material and soft actuators, soft grippers have gained relief in the field of soft robotics in the last years. Soft grippers have considerable flexibility that allows them to grasp a variety of objects, in contrast to hard grippers, which are designed for a specific item. Using the principles of soft robotics, gripping tools with a greater robustness can be developed. This implies that they do not require changes in their programming or construction to manipulate different objects, and the precision needed to make the grips is reduced.

Knowledge Integration in Smart Factories
Knowledge integration is well explained by the human–organization–technology (HOT) approach known from knowledge management. This approach contains the horizontal and vertical interaction and communication between employees, human-to-machine, but also machine-to-machine. Different organizational structures and processes are supported with the help of appropriate technologies and suitable data processing and integration techniques. In a Smart Factory, manufacturing systems act largely autonomously on the basis of continuously collected data. The technical design concerns the networking of machines, their connectivity and the interaction between human and machine as well as machine-to-machine. Within a Smart Factory, machines can be considered as intelligent manufacturing systems. Such manufacturing systems can autonomously adapt to events through the ability to intelligently analyze data and act as adaptive manufacturing systems that consider changes in production, the supply chain and customer requirements. Inter-connected physical devices, sensors, actuators, and controllers form the building block of the Smart Factory, which is called the Internet of Things (IoT). IoT uses different data processing solutions, such as cloud computing, fog computing, or edge computing, to fuse and process data. This is accomplished in an integrated and cross-device manner.

Classification of Architected Materials for Additive Manufacturing
One of the main advantages of Additive Manufacturing (AM) is the ability to produce topologically optimized parts with high geometric complexity. In this context, a plethora of architected materials was investigated and utilized in order to optimize the 3D design of existing parts, reducing their mass, topology-controlling their mechanical response, and adding remarkable physical properties, such as high porosity and high surface area to volume ratio.

Additive Manufacturing of High Entropy Alloys
Alloying has been very common practice in materials engineering to fabricate metals of desirable properties for specific applications. Traditionally, a small amount of the desired material is added to the principal metal. However, a new alloying technique emerged in 2004 with the concept of adding several principal elements in or near equi-atomic concentrations. These are popularly known as high entropy alloys (HEAs) which can have a wide composition range.

Spare Parts with Additive Manufacturing of Aviation Industry
Additive manufacturing (AM) is a digital technology of layered fabrication by adding material where no cutting tool is required as in the case of a subtractive manufacturing process. AM is bridging the digital and physical world as a 3D computer-aided manufacturing (CAM) method. The usage of AM has made the supply chain of the aviation spare parts industry simpler, more effective, and efficient.

Utilization of Product Usage Information in Product Development
As emerging technologies such as IoT technologies become widespread, producers can collect large-scale product usage information (PUI) from different stakeholders, including retailers, customers, users, and the providers of product-related services such as maintenance, renting, and leasing. Its content, format, and quality are heterogeneous and cover, for example, service reports, review reports, and embedded systems’ measurements. This information provides producers a better understanding of user expectations, usage situations, product behavior, and performance.

A New Product Development Model for SMEs
The success of new product development (NPD) is of vital importance for the growth and prosperity of manufacturing companies. Complex product demands are increasing and companies must be able to produce the right products at the right time and at an affordable price; otherwise, they can quickly lose their competitive advantage. Especially vulnerable are small and medium-sized enterprises (SMEs) that can find it difficult to compete with larger companies on a global market and are also more prone to suffer from potential losses related to unsuccessful NPD, as they have a smaller set of both financial and non-financial resources. In order to survive in today’s highly competitive global market, small and medium-sized enterprises (SMEs) have had to transition from sequential to concurrent product development, which significantly shortens development cycles, reduces costs, and ensures high product quality.

High-Temperature Materials in Ammonia/Hydrogen Gas Turbines
This entry reviews the critical role of material selection and design in ensuring efficient performance and safe operation of gas turbine engines fuelled by ammonia–hydrogen. As these energy fuels present unique combustion characteristics in turbine combustors, the identification of suitable materials becomes imperative. Detailed material characterisation is indispensable for discerning defects and degradation routes in turbine components, thereby illuminating avenues for improvement. With elevated turbine inlet temperatures, there is an augmented susceptibility to thermal degradation and mechanical shortcomings, especially in the high-pressure turbine blade—a critical life-determining component.
