PurposeIndustry 4.0 (I4.0) influences the supply chain, including innovation, structure, availability and communication. It influences the supply chain by modifying how products are designed, manufactured, delivered and discarded for the sustainability of an organization. Sustainability emphasizes the use of optimal raw materials, efficient storage and delivery, on-time supply, productivity development, recycling, remanufacturing and refurbishing. The aim of this study is to identify and establish causal relationships among the key aspects that contribute to the success of I4.0-enabled sustainable supply chain (I4eSSC). The objective is to classify these components into discrete categories according to their causal and consequential linkages.Design/methodology/approachThis paper presents a three-phase hybrid Criteria Importance Through Inter-criteria Correlation and Grey Decision-Making Trial and Evaluation Laboratory (G-DEMATEL) framework to achieve the stated objectives. A study is conducted to empirically examine the Indian automobile sector in order to illustrate the suitability of the suggested framework.FindingsDuring the initial stage, a total of 26 success factors have been identified for the I4eSSC implementation. During the second part of the study, a total of 20 success factors were found and deemed critical success factors (CSFs).

Promotion of Stenotrophomonas sp. on the photosynthetic growth of microalgae exposed to high concentrations of formate

Formate is an important solar fuel, with large application potential in bioconversion. Especially, the win-win collaboration is achieved when formate is applied to the cultivation of microalgae, which combines the advantages from both artificial and natural photosynthesis. However, the inhibition of formate on the photosynthetic electron transport hinders the application of formate at high concentrations. The engineering or directed evolution of the regulation pathway is a case-by-case and time-consuming strategy. Here, we developed a new strategy by introducing a Stenotrophomonas sp. strain which was isolated and identified from the long-term self-evolution process of Chlamydomonas reinhardtii for adapting to high concentrations of formate. The co-culture with the strain or the fermentation broth relieved the inhibition of formate (50 mmol/L) on C. reinhardtii and promoted the growth of the microalga. Especially, the protein content increased significantly to nearly 50% of the dried weight. In addition, the co-culture also benefited the growth of both Chlorella pyrenoidesa and Synechocystis sp. PCC 6803 exposed to formate, which indicated broader applicability of this strategy. This strategy provides the opportunity to overcome the bottleneck in the formate-mediated artificial-natural hybrid photosynthesis and to aid the development of technologies for solar energy-driven production of bulk biomass, including proteins, by carbon dioxide reduction.

Zooming into CTC black-tea wine metabolites: A GC-MS-based study

This research was designed to propose a report on fermentation metabolomics of CTC (crush-tear-curl) tea wine (TW), a yeast-fermented broth of sugared CTC black tea infusion. The gas chromatography-mass spectrometry analysis of the tea wine revealed the presence of thirty-five metabolites, including the major compound glycerine with some potential antioxidant molecules and other bioactive agents (4H-pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl-; furfural; furfuryl alcohol; succinic acid; levulinic acid; palmitic acid; tyrosol, pyruvaldehyde; and 1-hexadecanol). The role of metabolites in the physicochemical, biochemical, and medicinal properties of TW has been discussed. Biomolecules responsible for the flavour of TW were as follows: glycerine derivatives; pyruvaldehyde; furfural; furfuryl alcohol; acetic, levulinic, succinic, and palmitic acids, etc. – which might develop a sweet, caramel-like, astringent, slightly sour and wine-like flavour and taste. Furthermore, on the basis of yeast metabolism, possible biosynthesis pathways of metabolites were designed aiming for fermentation metabolomics. The outcome of this study cross-verified physicochemical, biochemical, and medicinal properties of TW suggesting its acceptability. As the fields of both wine research and tea science continue to evolve, the findings of this study may encourage fermentation technology for product development from tea that may also boost the growth of the tea industry.

The Influence of the Age Factor on The Quest for Value for Money in The Phenomenon of Electronic Product Leveling

With the continuous development of electronic product technology, a large number of reasonably priced, high-performance flat products have appeared on the market. This phenomenon reflects that consumers are highly concerned about the price-performance ratio. The age factor plays an important role in consumers' purchasing decisions, and there are significant differences in the behaviors and preferences of consumers of different age groups in the pursuit of cost-effective products. In this paper, we conduct an in-depth analysis of the demand, purchasing behavior and preference of consumers of different age groups in the phenomenon of electronic product replacement, and explore how the age factor affects consumers' pursuit of cost-effectiveness. It is found that there are significant differences between teenagers, middle-aged people and the elderly in terms of their concern for cost-effectiveness, purchase decision-making process and brand preference. In the phenomenon of electronic product parity, young people are more concerned with appearance and trends, middle-aged people emphasize comprehensive value and rational comparison, and older people tend to choose brands that are easy to use and trustworthy. These differences are closely related to consumers' economic status, consumer attitudes, technology acceptance, and risk tolerance.

Integrating Citizen Participation in the Development of New ICT Services for Smart Cities

The transition of cities towards a smarter approach significantly benefits from citizen participation in the development and implementation of innovative information and communication technology (ICT) products and services. Despite the emergence of various initiatives in recent years aimed at guiding the development of smart cities, there is still a lack of effective strategies to actively engage citizens, businesses, and educational institutions during the creation of these products and services. This study describes a set of practices that includes four co-creation techniques to facilitate the effort of software system development in collaboration with citizens and other stakeholders. The SEMAT standard is used to create and represent a method in which these practices are distributed across four stages: focus, definition, development, and validation. In each stage, a practice is proposed that incorporates a co-creation technique and complementary activities from various software engineering disciplines to promote active citizen participation; stimulate idea generation; and facilitate the creation of necessary documents and components for the development of the desired software system, including design systems, code files, conceptual representations, and technical diagrams, among others. Finally, the applicability and completeness of the method are validated through expert consultation in the fields of software engineering and smart cities. Recognized procedures are followed to obtain qualitative and quantitative results, such as improvement actions (addition or removal of elements), levels of consensus or acceptance, and opportunities for future work.

The Potential of Microwave Technology for Glycerol Transformation: A Comprehensive Review

Glycerol is a major by-product in biodiesel manufacturing, which accounts for around 10% of the biodiesel volume. A surplus of glycerol has led to the development of technologies for production of value-added products using glycerol as a raw material, following the “waste as a resource” strategy. Various techniques are available to carry out glycerol transformation, viz. carrying out processes under thermal heating, application of ultrasonic or hydrodynamic cavitation, microchannel technologies, etc. Microwave-assisted organic synthesis (MAOS) is a simple and innovative technology, which can be considered as a means of intensifying these processes. This review describes microwave irradiation as a valuable energy-efficient alternative to conventional heating for the production of value-added chemicals from glycerol via dehydration, hydrogenolysis, esterification, transesterification, etherification, and oxidation. In general, innovative and potential catalysts, approaches, and technologies are discussed and critically evaluated in terms of the possibilities and potential for further industrial implementation

Aligning new product development with reverse engineering methodologies for headlamp jig

Abstract This study explores the combination of reverse engineering (RE) and new product development (NPD) methodologies to enhance the manufacturing process of headlamp jigs. RE, utilised as a benchmarking technique, aids in regenerating parametric designs or innovating new product concepts. The distinctive appearance relies on headlamps with protective coatings cured at high temperatures in UV ovens, necessitating jigs capable of withstanding such conditions. Hence, employing RE becomes crucial to fortifying jig performance. While RE often signifies innovation or refinement, the current headlamp jig encounters deformation issues during manufacturing due to high curing oven temperatures and intense water jet cleaning pressures. The absence of an effective NPD approach exacerbates persistent jig deformation challenges. NPD, encompassing stages like idea generation, concept development, design, testing, and marketing, is crucial. The absence of NPD, along with the complexity of RE, could prolong timelines and escalate expenses in bringing marketable products to fruition. This study aims to propose an NPD model for headlamp jigs, leveraging RE methodologies to enhance composite jig fabrication processes. The integration of PDCA methodologies within NPD intends to rectify deformation issues while optimizing manufacturing processes for superior headlamp jigs.

Mathematical model of the system performance mode for simultaneous separate well operation

Relevance. The trend of oil production technology development is related to many relevant topics. One of such actual directions is the technology of simultaneous separate well operation, in particular, including two electric centrifugal pumps and double-sided submersible electric motor. The presence of two formations at the bottomhole implies the selection of the optimal layout, technological parameters of pumps pumping oil. Considering production from two independent formations in the well according to the mentioned technology, there is a high need in selection of correct parameters of installations at the design stage. In the absence of correct selection of technological parameters of units at the design stage, further operation of a well with two independent formations can be economically inexpedient, and in some cases unrealizable, which is due to a number of reasons. First, if the necessary underbalance is not provided for each particular formation, counterflow of fluid may occur and one of the pumps will not participate in the production process. Secondly, when operating an arrangement, which capacity significantly exceeds the capacity (fluid flow from the reservoir) of the well, there is a possibility of pumping failure and, as a consequence, there is a risk of potential failure. In this regard, an extremely urgent task at the moment is to ensure correct selection of technological parameters of electric centrifugal pump units used in simultaneous separate operation of wells with two independent formations. Aim. Development of a mathematical model that allows selecting the optimal technological parameters of the arrangement consisting of two electric centrifugal pumps and a double-sided submersible motor, used for simultaneous separate operation of wells with two independent formations. Methods. Numerical simulation methods for analyzing the operation mode of electric centrifugal pumps in conditions of oil production from two independent reservoirs. Results and conclusions. It was obtained that the developed mathematical model of the system operation mode for simultaneous separate operation of wells allows to estimate the potential of each individual selected pump during oil production (in time dynamics) by analyzing the depression on each individual reservoir, as well as modeling the process taking into account the potential backflow of liquid and supply failure.

Structural and Electrochemical Characterization of Nanographenes Adlayers on Au(111)

The development of efficient hydrogen production technology by water splitting electrolysis with low overvoltage is underway to realize a hydrogen society, and the development of a technology to precisely design and sheet the chemical structure along with catalyst development is very important to understand the electrocatalytic reaction mechanism such as hydrogen evolution and oxygen reduction reaction and the effect of gap spacing on the active site at the nanoscale. This is very important for visualizing and understanding the mechanisms of electrocatalytic reactions, such as hydrogen evolution and oxygen reduction reactions (HER and ORR), and the effect of gap spacing on the active sites at the nanoscale. For example, it has been reported that ORR activity is enhanced on surfaces with adsorbed hydrophobic organic molecules on Pt compared to that on clean surfaces (Nat. Commun. 2018, 9, 4378). The effect of nanopores (vacancy sites) on the HER is unclear, although it is attributed to the limited reaction sites of Pt atoms owing to the adsorption of organic molecules. Furthermore, it is difficult to control the size of the nanopores and their dispersion (distance between nanopores) at the nano-level using a top-down approach, in which graphene sheets are mechanically and chemically processed, and a bottom-up 2D sheet fabrication method should be established. The development of a technique to precisely design chemical structures and fabricate sheets is important to understand the electrocatalytic reaction mechanism at the nanoscale and to visualize the effect of nanopore size and spacing on the active sites at the nanoscale.In this study, we investigated the formation of nanostructures by the intermolecular condensation of nanographene, such as ovalene and dicoronylene (Fig. 1), and investigated the thermal condensation conditions by adsorption on a Au(111) substrate under various conditions. The pore size of the nanostructures formed by ovalene and dicoronylene was characterized by using a scanning tunneling microscope (STM).A clean Au (111) substrate was immersed in an ovalene- and/or dicoronylene-saturated benzene solution for 10 – 60 s, and the coated Au(111) electrode was investigated using cyclic voltammetry (CV) measurements. The current density was significantly reduced before and after the vacuum heat treatment, suggesting that the ovalene molecules were rearranged on Au(111) and condensed between molecules. In addition, as a result of observation of the surface state in the atmosphere with STM, it was found before heating (Fig. 2a), confirming that the ovalene molecule was adsorbed over a wide area, and after heating (Fig. 2b), nanostructures with voids of 2.5 ~ 3 nm in diameter were observed. These results suggest that condensation may have occurred between the ovalene molecules due to heating, resulting in the formation of nanostructures with many nanopores. In contrast, dicoronylene forms a diamond-shaped lattice structure with sides of approximately 1.5 to 2.5 nm. Considering the molecular size of dicoronylene, it is difficult to judge whether intermolecular condensation among dicoronylene molecules occurred; however, the adlayer structure was different from that observed at room temperature. These results strongly suggest that intermolecular condensation reaction among ovalene and dicoronylene occurred on Au(111) upon elevating the temperature in vacuum. From the CV measurements, no significant change in the electric double-layer region was observed before and after the vacuum heating treatment; however, we found small change in the overpotential on the hydrogen evolution reaction.
