The Effect of Miscibility and Morphology of Porphyrin Donors and Non‐Fullerene Acceptors on Exciton Dissociation Processes: A Quantum Chemical and Molecular Dynamics Study

AbstractPorphyrins and their derivatives have been employed extensively in organic solar cells (OSCs) in recent years. However, a deeper understanding of the exciton dissociation process for the porphyrin donor/non‐fullerene acceptor (NFA) interface is still lacking. Herein, we have combined quantum chemistry and molecular dynamics simulations to explore the combination of mono and dimer porphyrin donors with various types of NFAs. The work reveals that the key issue lies in the exciton dissociation process of porphyrin materials, which have strong crystallinity to increase spacing (more than 5.0 Å), resulting in lesser miscibility and weaker intermolecular π‐π stacking. The pathway for exciton dissociation will be limited by the small number of high‐energy charge transfer (CT) states. To solve the above‐mentioned issues, we implement an improved strategy for modifying the side chain of the terminal unit, reducing the stacking distance to 4.4 Å, while the number of CT states reaches up to 40 % (3/A3 style 1). Additionally, the results also indicate the development potential for all porphyrin OSCs, particularly, the charge recombination (kCR) rate of the 1/Rf‐Iso system is lowered by nearly nine orders of magnitude. This research may offer fresh perspectives for extending the application range of porphyrin materials in OSCs.

Implementation of measurement uncertainties into vehicle noise regulation

The current vehicle noise regulation UN R51.03, does not provide specific considerations for the measurement uncertainties related to the measuring method for external pass-by noise. The measurement method is based on the ISO Standard ISO 362-1:2007. While the ISO system mandates a detailed description of the expected uncertainties, the UN-ECE has not overtaken these uncertainty considerations, as the application of the test method is limited to type-approval and conformity of production measurements, both under control of the vehicle manufacturer in agreement with a type- approval authority. The UN ECE Working Party on Noise and Tyres (GRBP) in Geneva established in 2019 an Informal Working Group on Measurement Uncertainties (IWG MU), to evaluate the measurement uncertainty in general and to propose amendments to regulations to reduce the measurement uncertainty, starting with the most important sound emission regulations UN R51.03 (vehicles) and UN R117.02 (tyres). This paper describes the principal work of the IWG concerning the contribution of the different parameters to the overall expanded uncertainties when testing vehicles according to the specifications in UN R51.03. The identified main contributors to the overall measurement uncertainties are variations due to the test track (site-to-site) and air temperature effects (day-to-day).

Theoretical study and experimental verification on a passive control system with isolators and dampers for NPPs

A hybrid passive control system named damped isolated structural system (DISO system) for nuclear power plant structures (NPPs) with double containments is proposed in this paper, in which the outer containment is non-isolated and the inner containment and equipment are isolated with connecting damper installed between two containments. Firstly, a connected single degree of freedom (CSDOF) model was proposed. Subsequently, the vibration characteristics and parametric correlation analysis of proposed systems based on CSDOF model were analyzed. The acceleration and dimensionless displacement variances were derived. The optimal value is related to structural parameters, such as the mass ratio η, ratio of natural vibration frequency γ and structural damping ratio ξiξo. Through data fitting and calibration, the closed-form expression of the optimal parameter κopt is provided. The accuracy of the expression is verified by numerical simulation. Finally, a shaking table experimental study on the scale model was conducted to verify the theoretical results. The optimal damping parameter in the experimental study was calculated by the fitting formula (κopt). The results show that with optimal parameter, the acceleration and displacement responses of DISO system are both lower than traditional isolated structures (ISO system). The shaking table test results are well consistent with that of theoretical investigation conclusions.

The development of a digital twin concept system

Background: Digital twins are gaining ever-increasing attention from academies and industries to standardization bodies all over the world owing to their great capabilities and fundamental values in the coming fourth industrial revolution. However, there is no consistent set of definitions or concept system for the digital twin domain yet. Methods: This paper summarizes the methodology of developing a concept system with integrating ISO standards guidelines and system thinking methods, analyzes the polysemy phenomenon of the term "digital twin", and identifies the necessity to differentiate digital twin entity and digital twin system from the general term “digital twin”. Results: After analyzing nineteen definitions of digital twin (entity) and summarizing ten superordinate concepts from these definitions, this paper proposes that a digital twin entity is a kind of digital asset rather than digital representation. Based on the new superordinate concept and definition of digital twin entity, a systematic digital twin concept system is developed which consists of four parts: top-level ontology and taxonomy of entity, digital twin entity related concepts, digital twin system related concepts, and taxonomy framework related concepts. Conclusions: This work demonstrates the power and effectiveness of the combination of ISO terminology work standards, system thinking methods, and information modeling tools, lays a solid foundation for future concept systems development of other domains, and will provide useful input to the efforts of digital twin standardization.

Environmental Studies and Environmental Laboratory Testing in Accordance to ISO Standards

ISO’s standards have been applied not only by the manufacturing industries but also universities as well as research institutions. Three ISO standards are commonly applied: ISO 9001, ISO 17025, and ISO 14001. Although these three standards have differences in the purpose, criteria, and emphasis, these standards can be applied side-by-side by an organization. Eventhough, many questions arise when the organization undertake more than one ISO. These questions, for examples, are: Is it not enough possessing just one ISO, for example ISO 9000 series only? What is the relation between one ISO to another? What is the relation between ISO and the existing regulations? Following the ISO system there is an internal affair in the institution that maintains and manages the quality system according to ISO, for example ISO 14000, environmental management standards. On the other hand, there is a research group in the institution that performs technical services for environmental laboratory testing and environmental research and studies. What are actually the difference functions between these two activities? This paper tries to conduct study in order to give answers for those particular questions. This paper is neither intended for describing ISO in details nor for tutorial purposes. Either comprehensive training or implementing ISO is conducted by a special authorized agency.

The assessment of the ISO GPS system implementation with a GPS maturity model

For more than twenty years, the international system for the geometrical tolerancing of components has been reformed. With the aim for a non-verbal specification and verification of components, the ISO system for Geometrical Product Specification and Verification (ISO GPS system) has emerged. Due to the necessary extensive specification language, which additionally contains mathematical descriptions, references, 3D specifications, defaults, rules for manufacturing and measurement etc., the ISO GPS system has now reached a complexity, which cannot easily be understood and decoded by the different engineers and departments in the companies, especially small and medium-sized enterprises as well as handicraft businesses. This makes an application in the entrepreneurial practice almost impossible. A structure and guidelines for the application are currently missing. Furthermore, there is a lack of requirements and a general approach for a necessary multi-layered training of specialists like engineers or machine workers as well as managers. There are also no generally accepted standards for the application of the ISO GPS system in companies. Often, small businesses, as contractors to large companies, have to deal with the challenges due to ISO GPS conform specifications. This problem has recently been amplified by the rapid progress of digitization and the increased use of 3D data including PMIs or application of 3D model-based definitions.For this reason, an implementation strategy for an integrated GPS system for small and medium-sized enterprises has been developed as part of a current research project at the Chemnitz University of Technology. To overcome the difficulties caused by the complexity of the ISO GPS system, an agile training concept based on GPS competencies, a roadmap for the integration process, and a GPS maturity model for the assessment of the process have been developed. Fundamental results of the research project with focus on the development of the GPS maturity model for a transparent agile implementation process are presented in this paper.

Improving of preventive management for flat rolling products quality indices

Based on the combination of ISO and Lean system tools, the methodology of continuous optimization of technology and quality improvement of rolled steel has been improved. To assess the condition and determine the production level to set limits to process indices the use of colored markers was suggested. The improved flat rolling quality control methodology is based on the use of Deming cycle and includes the use of such analysis tools as Fishbone (Ishikawa) diagram, Pareto principle, distribution diagrams, 3σ rules and Shewhart control charts. For the first time, differentiated corrective solutions for plate steel which is produced with different levels of process stability and quality indices are suggested. The inspection was carried out with the data from the mechanical properties of flat steel products 14 mm thick from K60 steel, produced by thermo-mechanical controlled process on a plate mill 3600. Introduction of the methodology allowed to reduce the standard deviation of yield strength, tensile strength and percentage elongation after fracture of the studied rolled products by 44%, 31% and 46%, respectively, indicating an overall increase in technology stability and quality indices and implementation of an effective tool for their preventive control.

АНАЛИЗ ПРИМЕНЕНИЯ ОБОЗНАЧЕНИЙ ISO В СИСТЕМЕ ЕСКД

GOST 53442-2015 introduced a novelty into the ESCD system in the form of a conventionally graphical designation of the theoretically exact TED size, fit requirements and many other designations, which of course caused a lot of mistakes due to misunderstanding of this definition by various divisions of the production enterprise. Modern systems of assembly operations in the ISO system differ significantly from the traditional requirements for designations given by the Unified System of Technological Documentation. On the one hand, these requirements, additional signs significantly increase the number of symbols on the assembly drawing, which can make it difficult to read the drawing, on the other hand, these designations adopted by the ISO system are increasingly found in the designation of drawings made by Russian companies, to which, however, the requirements of compliance with international standards can be applied - and not only in the field of compliance with the quality of finished products, systems for the availability of safe production, but above all international rules for the designation of drawings.

The Significance of the ISO System in Jordanian Construction Companies.(Dept.C)

It becomes essential for the Jordanian companies to be credited with ISO, particularly after the great effort that has been exerted by His Majesty King Abdullah The Second and the Jordanian government to join many international organizations, such as the World Trade Organization. Also, the Jordanian companies must improve its product in order to inter the international competition and then contribute in developing the national economy. The importance of this research is to highlight through the study and evaluation of implementing the ISO system in construction companies' management. In addition to analyzing the impact of implementing the twenty demands for ISO, each one at a time, on increasing the profit, the company's development and the safety in the work environment of these companies. Five construction companies that have been achieved the ISO certificate were chosen for the purpose of realizing this research's objectives. Moreover, many prolonged interviews were conducted with the Quality Managers of these companies. The researcher concluded that the adoption of this system (ISO) largely contributes to increasing the companies profitability, develops and insures higher safety measures in these companies. Furthermore, there are many other tangible and less obvious benefits. The twenty ISO implementation demands are not of the same importance, some are very significant and others are not. Thus, it was a wise decision to adopt the revise ISO system. However, the existing ISO system has ignored some other important issues which are mainly related to construction. Of these issues are construction claims and dispute, preparing the vender and order changing. Therefore, this paper suggests a new system which may be called as ISO-Construction to deal with the significant requirement that would be of interest to construction companies.

Managing the effectiveness of strategic decisions to rationalize the system of maintenance and repair of passenger cars

Reducing the cost of maintaining a fleet of passenger cars is one of the key objectives of the operating company as part of its strategic management. The article describes the criteria by which can be evaluated the effectiveness of strategic decisions in the field of rationalization of the system of maintenance and repair of passenger cars. The process of rationalization of this system is presented in accordance with the Deming — Schuhart cycle (PDCA) with feedback. This process provides for monitoring the effectiveness of the implemented changes in the system on the basis of IT-technologies and processing "Big Data" on three conditions: efficiency of use (C-criterion), integrated reliability (availability) ( К -criterion) and functional safety of passenger cars ( λ -criterion). The C-criterion characterizes the savings from reducing the costs of maintenance and repair of cars by introducing appropriate changes to the system of maintenance and repair of passenger cars. At the same time, the savings will be expressed as a reduction in the cost of the life cycle of cars in terms of technical content when introducing changes to this system. The К -criterion characterizes the change in the working time fund of cars and, as a result, determines the amount of profit (lost profit) from the increase (decrease) in the working time of cars after introducing changes to the system of maintenance and repair of passenger cars. Within the ^-criterion, comprehensive reliability indicators are used — the availability factor and the technical availability coefficient. λ -criterion characterizes the current safety state of trains in terms of passenger facilities on the basis of functional performance of cars safety. A negative indicator was adopted as a similar indicator — the intensity of dangerous railway failures that led to a violation of the safety of train traffic. The given approach was developed in the tradition of the process control methodology according to the ISO system of standards and the IRIS standard of the railway industry. Currently, there are methodological developments and hardware/software that allow to move towards practical implementation of the described approach to effective management in the field of rationalizing the maintenance and repair of passenger cars by the operating company as part of the overall strategic management.

Silicon-doped indium oxide – a promising amorphous oxide semiconductor material for thin-film transistor fabricated by spin coating method

Silicon-doped indium oxide (In-Si-O or ISO) has been investigated as the channel material of thin-film transistor (TFT) for the application of next generation flat panel displays. Because solution processing is simple, low cost and low power consumption in comparison with physical vapour deposition, it is a potential candidate for TFTs fabrication. We have been exploring research on TFT using ISO system via spin coating method. In this work, the performance of 3 at.% Si-doped indium oxide TFT has been improved with the highest mobility of 3.8 cm2/Vs without the passivation layer.

X-RAY CONTROL OF WELDED JOINTS ACCORDING TO GOST AND ISO SYSTEMS

The results of comparative analysis of assessing modes, parameters and means of radiographic control of welded joints of critical duty using the Russian (GOST) and international (ISO) standards are presented. Comparison was carried out by the sensitivity of control, permissible radiation energy (affecting the formation of the contrast of the radiation image), and minimum focal length (determining the sharpness of the resulting optical image). Requirements of the ISO system for the sensitivity of control are higher, than that of the State standard specification system. The sensitivity assessment in the ISO system is carried out using the wire indicator, the dimensions of which are smaller than the dimensions of the grooves of the groove sensitivity standard, regulated by GOST. However, the choice of the radiation energy in the system requirements GOST is stricter than that in the ISO system. This provides enhanced contrast of the generated radiation image. The conversion of the radiation image into an optical one using the ISO system is carried out using film systems of a high optical density. According to the ISO requirements transformation of the radiation image to the optical one is to be carried out using film systems of the certain class. And, as a result, transformation of the radiation image to the optical occurs in the field of high gradients. GOST imposes no requirement to film systems, since there is the only one class of domestic film on the market. The requirements to the minimum allowable focal length (GOST) are higher compared to the ISO system, which makes it possible to obtain better sharpness of radiographic images. Performance monitoring according to GOST also exceeds that of ISO. As a result, we can conclude that the quality welded joints should be monitored using the complete set of the accepted standards.

Tolerance system for linear maximum material sizes and their inspection by calibers

The paper deals with the topical issue of quality assurance of technical products according to precise geometrical specifications. The aim of this work is to develop proposals for improving the system of tolerances and fits for linear sizes in the international standard ISO 286-1. The objective of this work is to increase the level of adequacy of the linear size tolerance model to the real dimensional elements of the parts. Two sizes of dimensional element - maximum material size and minimum material size are basic concepts of F. W. Taylor principles. The difference between the size of the maximum material holes (the minimum size) and maximum material size of shaft (maximum size) determines the type of the pair fit. In the ISO system of tolerances the ideal model of a dimensional element without form deviations of the surfaces is applied to linear dimensions. The ideal model is inadequate to the real dimensional element. The rejection of the form deviations resulted in the loss of the dimensional element minimum material size. The tolerance interval limits the upper and lower limits and the deviations of only the maximum material size. Validity inspection of the maximum material size by the upper and lower limit dimensions shall be provided by complete through and no-go gauges. Such monitoring will provide a fit with the required limiting values of clearances and tightness. Form tolerances in the diameter expression that is joined to the dimension tolerance for maximum material size increase the tolerance interval and make the minimum material limit that should be monitored by the no-go two-point gauge. Inconsistencies of the international tolerances system can be eliminated if to move from an inappropriate ideal model of a dimensional element to to the adequate real model considering the form deviation.
