Abstract

The cell wall is a complex structure mainly composed of cellulose microfibrils embedded in a cohesive hemicellulose and pectin matrix. Cell wall structural proteins, enzymes and their inhibitors are also essential components of plant cell walls. They are involved in the cross-link of cell wall polysaccharides, wall structure, and the perception and signaling of defense-related elicitors at the cell surface. In the outer part of the epidermal cells, the polysaccharides are coated by the cuticle, consisting of hydrophobic cutin, suberin and wax layers. Lignin, a macromolecule composed of highly cross-linked phenolic molecules, is a major component of the secondary cell wall. The cell wall is the first cell structure on which interactions between plants and a wide range of other organisms, including insects, nematodes, pathogenic or symbiotic micro-organisms take place. It not only represents a barrier that limits access to the cellular contents that provide a rich nutrient source for pathogens but serves as a source of elicitors of plant defense responses released upon partial enzymatic degradation of wall polysaccharides during infection. Modification of the plant cell wall can also occur at the level of plasmodesmata during virus infection as well as during abiotic stresses. The fine structure and composition of the plant cell wall as well as the regulation of its biosynthesis can thus strongly influence resistance and susceptibility to pathogens. This Research Topic provides novel insights and detailed overviews on the dynamics of the plant cell wall in plant defence, parasitism and symbiosis and describes experimental approaches to study plant cell wall modifications occurring during interaction of plants with different organisms.

Abstract

ca. 200 words; this text will present the book in all promotional forms (e.g. flyers). Please describe the book in straightforward and consumer-friendly terms.[Aluminium alloys are the most common non-ferrous materials utilised for a wide range of engineering applications, namely, automotive, aerospace, mould and structural industries, among others. The wide spread of these alloys in the modern word is due to the unique combination of material properties combining lightness, excellent strength, corrosion resistance, toughness, electrical and thermal conductivity, recyclability, and manufacturability. Last but not least, the relatively low cost of aluminium extrusion is important as it makes aluminium alloys very attractive for applications in different key sectors of the world economy. Despite great interest, extensive previous research, and knowledge accumulated in the past, recent advances in production and processing technologies, combined with the development of new and more ingenious and competitive products, require a profound understanding of the physical and mechanical behaviour of such alloys, specifically in terms of modelling and predictions of the fracture and fatigue life of aluminium alloy components. This Special Issue aims to gather scientific contributions from authors working in different scientific areas, including the improvement and modelling of mechanical properties, alloying design and manufacturing techniques, the characterization of microstructure and chemical composition, and advanced applications.

Abstract

The desired properties of surface components include the improvement of different properties, such as aesthetic appearance, oxidation resistance, wear resistance, mechanical properties, electronic or electrical properties, thermal insulation, wear, triboemission and corrosion resistance through barriers.These properties can be enhanced using different methods, such as by adding a coating. Nevertheless, the bulk of the material or substrate cannot be considered independent of the surface treatment. Metal cutting is one of the general machining methods used to achieve high accuracy and productivity for metal parts.The topics of the book “Manufacturing and Surface Engineering” include the full range of surface engineering aspects, i.e., surface integrity, contact mechanics, friction and wear, coatings and surface treatments, multiscale tribology, computational methods, and optimization techniques applied in surface engineering.Recent experimental works by Zhang, Li, Zhang, Zhang and Duan, and by other researchers outlined that coating layer surface treatments may increase the damping behavior of thin-walled mechanical components vibrating in flexural conditions. Nevertheless, it was also experimentally found by the authors that most of these coating surface treatments had a negligible or null effect with respect to the vibrational damped response in testing or operating conditions. Ciniero, Le Rouzic and Reddyhoff report the potential of measuring charged particle emissions and/or tribocharging for the study or monitoring of the failure of coatings. The spatial information of triboemission allows the identification of the exact time and location of the failure. The evolution of the failure during sliding and the change in the characteristics of the contact are also monitored. After studying the effect of the Ti content on the performance of FeCoCrNiAlTix, He, Zhang, Lin, Zhang, Dong and Li establish that the structure of FeCoCrNiAlTix coatings consists of two kinds of BCC phases. With the continuous increase in Ti content, the number of eutectic structures decreases, accompanying the increase in the proeutectic phase and the Ti-rich second phase is precipitated out. Abutaha, Abdul Razak, and Ibrahim developed an experimental investigation into the engineering properties of concrete incorporating POC as an aggregate and filler material. This approach offers an environmentally-friendly solution to the ongoing waste problems associated with palm oil waste material.Liu and Janssen studied the effects of impact on the wear of the structural steel S235 in various liquids. When the impact is small, corrosion plays a dominant role, thus the sample in seawater wears the least due to the beneficial interaction with abrasion. However, when the impact is large, the wear rates of three liquids do not show a noticeable difference, because the wear mechanism changes from material removal to mainly plastic deformation. The influence of corrosion becomes a minor influencing factor when subject to impact.Vázquez Martínez, Salguero Gómez, Batista Ponce and Botana Pedemonte analyzed the different treatments obtained through setup parameter combinations to obtain samples with widely varying features, according to the thickness of the treated layer and the incidence depth of the laser beam. This diversity of samples shows a range of color tonalities from soft gold to medium gray and blue. Microstructural changes and oxidation layer generation provide a significant increase in the material hardness, reaching Vickers hardness values close to 1000 HV for high intensity treatments.Takada and Sasahara studied the FSB process using four levels of tip radius burnishing tools and investigated their effect on surface roughness, hardness and residual stress for a 0.45% C steel shaft. The thickness of the hardened layer increased as the tool tip radius decreased. The hardness value of the processed layer reached 600 HV. The residual stress on the processed surface was compressive when a radius tool with a smaller tip was used, and the residual stress turned tensile when a radius tool with a larger tip was used.Vereschaka, Kataeva, Sitnikov, Aksenenko, Oganyan and Sotova searched for patterns that allow a reliable justification for the choice of the composition of coatings and their micro- and nanostructures depending on the material being machined and the cutting regimes (in particular, the cutting speed).Amadori, Catania and Casagrande investigated experimentally eight different innovative composite solutions. A significant increase in the damping behavior was observed for all of these solutions with respect to the uncoated components, and with respect to the already known solutions that have previously been investigated by these authors and other researchers. The coating solution employing an Al2O3 powder + matrix, made using a screen-printing and curing technology on an Al alloy substrate, proved to be the most effective technology with respect to the aim of this work. Catania and Strozzi investigated the performance of different solutions in a free and forced flexural vibration response; they propose a simple model based on the assumption of a multi-layer, zig-zag beam, which also locally models the dissipative actions at the interface between the layers. Some virtual prototyping application examples are also reported.

Abstract

The continuous miniaturization of products and the growing complexity of their embedded multifunctionalities necessitates continuous research and development efforts regarding micro components and related micro manufacturing technologies. Highly miniaturized systems, manufactured using a wide variety of materials, have found application in key technological fields, such as healthcare devices, micro implants, mobility, communications, optics, and micro electromechanical systems. Innovations required for the high-precision manufacturing of micro components can specifically be achieved through optimizations using post-process (i.e., offline) and in-process (i.e., online) metrology of both process input and output parameters, as well as geometrical features of the produced micro parts. However, it is of critical importance to reduce the metrology and optimization efforts, since process and product quality control can represent a significant portion of the total production time in micro manufacturing. To solve this fundamental challenge, research efforts have been undertaken in order to define, investigate, implement, and validate the so-called “product/process manufacturing fingerprint” concept. The “product manufacturing fingerprint” concept refers to those unique dimensional outcomes (e.g., surface topography, form error, critical dimensions, etc.) on the produced component that, if kept under control and within specifications, ensure that the entire micro component complies to its specifications. The “process manufacturing fingerprint” is a specific process parameter or feature to be monitored and controlled, in order to maintain the manufacture of products within the specified tolerances. By integrating both product and process manufacturing fingerprint concepts, the metrology and optimization efforts are highly reduced. Therefore, the quality of the micro products increases, with an obvious improvement in production yield. Accordingly, this Special Issue seeks to showcase research papers, short communications, and review articles that focus on novel methodological developments and applications in micro- and sub-micro-scale manufacturing, process monitoring and control, as well as micro and sub-micro product quality assurance. Focus will be on micro manufacturing process chains and their micro product/process fingerprint, towards full process optimization and zero-defect micro manufacturing.

Abstract

Nowadays, trust is an important determinant in the development of modern organizations. Not only is it becoming an increasingly important element of relationships between entities, but, above all, it positively influences the building of an organization's intellectual capital. This capital can be defined in different ways, but its definition always references elements that determine the potential of sustainable organizations, often in human, social, relational, organizational, and innovation dimensions. Trust is increasingly becoming the key determinant of this capital (Ko?uch, Lenart-Gansiniec, 2017). Trust also has a number of different definitions. However, the basis of many of these definitions is the building of relationships focused on developing some kind of individual or inter-organizational link. Organizational trust is a complicated concept, and it is the basis of all organized activities performed by people in the organization, largely because trust is needed to develop relationships with integrity and commitment. Thus, it is interesting to study the relationship between trust and the building of the intellectual capital of sustainable organizations. Indeed, intellectual capital plays a special role here. It is a guide and a platform for achieving not only a competitive advantage for the sustainable organization, but also a source of value creation in the short and long term. Thus, this strategic hybrid, composed of a business model, strategy, and business processes, is favorable to the development of intellectual capital (Jab?o?ski 2017). Trust is an element that ties this capital to relationships in business. Moreover, it has an integrated character (R.C. Mayer, J. H. Davis, F. D. Schoorman 1995). Assuming that, nowadays, the network paradigm is becoming increasingly important, it is worth asking how the mechanism of building trust-based intellectual capital in a sustainable organization functions as its key asset in the network environment.
