Abstract

Purpose

Crystallization is the process widely used for components separation and solids purification. The systems for crystallization process evaluation applied so far, involve numerous non-invasive tomographic measurement techniques which suffers from some reported problems. The purpose of this paper is to show the abilities of three-dimensional Electrical Capacitance Tomography (3D ECT) in the context of non-invasive and non-intrusive visualization of crystallization processes. Multiple aspects and problems of ECT imaging, as well as the computer model design to work with the high relative permittivity liquids, have been pointed out.

Design/methodology/approach

To design the most efficient (from a mechanical and electrical point of view) 3D ECT sensor structure, the high-precise impedance meter was applied. The three types of sensor were designed, built, and tested. To meet the new concept requirements, the dedicated ECT device has been constructed.

Findings

It has been shown that the ECT technique can be applied to the diagnosis of crystallization. The crystals distribution can be identified using this technique. The achieved measurement resolution allows detecting the localization of crystals. The usage of stabilized electrodes improves the sensitivity of the sensor and provides the images better suitable for further analysis.

Originality/value

The dedicated 3D ECT sensor construction has been proposed to increase its sensitivity in the border area, where the crystals grow. Regarding this feature, some new algorithms for the potential field distribution and the sensitivity matrix calculation have been developed. The adaptation of the iterative 3D image reconstruction process has also been described.

Abstract

Purpose

This paper aims to describe the influence of maleinized linseed oil (MLO), when used as a lubricant, on the thermal and rheological properties of PLA/MWCNTs (polylactic acid/multi-walled carbon nanotubes) and PLA/HNT (halloysite nanotubes) nanocomposites, as a reference for application in 3D printing processes.

Design/methodology/approach

Nanocomposites were obtained by melting in a twin-screw extruder, mixing PLA with MWCNTs and HNTs in different percentages of 0.5, 0.75 and 1 Wt.% for subsequent mixing by the same process with 5 phr MLO, for application in additive manufacturing, as analyzed by means of differential scanning calorimetry (DSC), capillary rheometry, melt flow rate (MFL) and field emission scanning electron microscopy (FESEM).

Findings

The results obtained for thermal characterization by using DSC indicate the non-variation of glass transition temperature Tg = 62 ± 2°C and a melting temperature (Tm) around 170°C. Crystallization temperature dropped by approximately 12°C, which should be kept in mind during the transformation processes. The values obtained by capillary rheometry indicate that the material’s viscosity is reduced by the influence of the MLO plasticizer’s lubricant effect on the PLA’s molecular structure. The melt flow index values confirm a rise of approximately 46% in the flow index and back up the capillary rheometry results. The values obtained were as follows: PLA/0.5 Wt.% MWCNT/MLO 5 phr 54.07, PLA/0.75 Wt.% MWCNT/MLO 5 phr 53.46, PLA/1 Wt.% MWCNT/MLO 5 phr 51.84y PLA/0.5 Wt.% HNT/MLO 5 phr 61.8, PLA/0.75 Wt.% HNT/MLO 5 phr 68.3 and PLA/1 Wt.% HNT/MLO 5 phr 71.2 g/10 min. Apart from the nanocharge distribution, the information obtained from the FESEM shows the existence of a cluster, which could have been avoided by more energetic stirring during the nanocompound manufacturing process.

Social implications

This paper presents an analysis of the insertion of plasticizer in nanocomposites for the application in additive manufacturing processes in fusion deposition modelling (FDM) system.

Originality/value

This is a novel original research work.

Abstract

Purpose

As the crystallization of Chinese wisdom and the shared wealth of all humanity, the Socialist Political Economy with Chinese Characteristics (SPECC) not only reveals the specific traits of SPECC but also indicates the general rules of the global economic development, showing both nationality and internationality. The paper aims to discuss this issue.

Design/methodology/approach

Being aware of the nationality of the SPECC is of great importance. It requires to integrate the basic Marxist principles with the realities of China, and meanwhile draw lessons from, not just simply copy, the strengths of other countries. The authors must adhere to the basic principles of the SPECC.

Findings

From the perspective of past practices, the SPECC has not only provided theoretical guidance for China’s reform and development, but has also given references to some countries, especially developing countries under reform and transition.

Originality/value

SPECC should be based on China’s conditions and practices, absorb China’s traditional cultural essences, draw lessons from other nations’ positive theoretical and practical results, propose theoretical viewpoints independently and initially, and construct a distinct academic system and discourse system. In this way, China would work to develop the characteristics and advantages of the SPECC, and contribute Chinese wisdom to the development and improvement of world economics and economics theories.

Abstract

Purpose

China’s economic development in the past 40 years has an array of distinctive features that have attracted the attention of the world. The paper aims to discuss this issue.

Design/methodology/approach

The analysis logic is as follows: with regard to the mechanism, the above factors were met in a timely manner and jointly contributed positive energy to China’s economic growth, with the increase in the savings rate as the necessary condition and foundation, and the increase in the savings rate is attributed to the explosive expansion of the financial system at the beginning of reform and the formation of positive incentives for residents, enterprises and governments at all levels, and the expansion of the financial system and the formation of positive incentives are clearly the crystallization of the wisdom of Chinese-style progressive reform.

Findings

Therefore, we have every reason to believe that the growth prospects of the Chinese economy remain bright. The author is nonetheless confident that the new two-step strategy for economic development will be realized, proposed by the 19th CPC National Congress.

Originality/value

Moreover, the growth of China’s economy has long been accompanied by the “double surplus” of current accounts and capital and financial accounts in the international balance of payments, which is not completely consistent with the traditional paradigm of development economics. These phenomena are so unique that the international community calls it the “Mystery of China” or “China’s Development Path.”

Abstract

Purpose

This study aims to analyze the factors, evaluation techniques of the durability of existing railway engineering.

Design/methodology/approach

China has built a railway network of over 150,000 km. Ensuring the safety of the existing railway engineering is of great significance for maintaining normal railway operation order. However, railway engineering is a strip structure that crosses multiple complex environments. And railway engineering will withstand high-frequency impact loads from trains. The above factors have led to differences in the deterioration characteristics and maintenance strategies of railway engineering compared to conventional concrete structures. Therefore, it is very important to analyze the key factors that affect the durability of railway structures and propose technologies for durability evaluation.

Findings

The factors that affect the durability and reliability of railway engineering are mainly divided into three categories: material factors, environmental factors and load factors. Among them, material factors also include influencing factors, such as raw materials, mix proportions and so on. Environmental factors vary depending on the service environment of railway engineering, and the durability and deterioration of concrete have different failure mechanisms. Load factors include static load and train dynamic load. The on-site rapid detection methods for five common diseases in railway engineering are also proposed in this paper. These methods can quickly evaluate the durability of existing railway engineering concrete.

Originality/value

The research can provide some new evaluation techniques and methods for the durability of existing railway engineering.

Abstract

Purpose

This study aims to offer novel insights on how industrial marketing might contribute to bringing innovations to market in the peculiar case of health care. This study aims at shedding first light on how the alignment between dissemination and exploitation activities might contribute to bringing to market innovations developed by public–private partnerships funded by the European Commission (EC).

Design/methodology/approach

The theoretical development comes from an inductive research design based on the 42-month pan-European H2020 research project NESTORE aimed at developing an integrated portfolio of innovations for the healthy aging of European citizens.

Findings

This study advances the theory and practice of industrial marketing in health care by conceptualizing an actionable method to align dissemination and exploitation activities within EC-funded projects, facilitating that innovations will go to market. The method is composed of five phases. First, an external analysis to define market opportunities and users’/stakeholders’ needs. Second, an internal analysis to identify the most promising exploitable outputs. Third, scenarios crystallization to define the most suitable scenarios (business models) to bring the selected exploitable outputs to market. Fourth, exploitation and dissemination alignment through the identification and involvement of the most relevant stakeholders. Fifth, scenario refinement and business plan.

Originality/value

This study is relevant because many EC-funded projects still fail to move innovations from labs to market, thus limiting the benefits for the European citizens and the competitiveness of Europe with respect to the USA and China. Although this relevance, past studies overlooked the peculiar context of EC-funded innovation projects, privileging pharmaceutical and biomedical companies. This study advance theory and practice of industrial marketing in health care.
