Abstract

Purpose

The purpose of this paper is to study the repeatability of path manufacturing in the drop on demand inkjet printing process and the influences of environmental and application factors on path resistance.

Design/methodology/approach

Paths were printed as multiline paths in packets one-, two- and three-layer paths on polyimide substrates using nanoparticle silver ink. The sintering conditions were determined experimentally. The paths were subjected to climatic and shock exposures and to bending processes. The resistance, profile and width of the paths were measured and analyzed. The temperature distribution for electrically heated paths was measured to identify the defects.

Findings

This research shows the repeatability of printing processes and identifies the sources that cause diversification in path parameters after the whole technological process. The influence of shock, climatic and mechanical exposures on path electrical properties is indicated. An effective method for identifying defects thermally is shown.

Research limitations/implications

The research could have limited universality by arbitrarily use of substrate material, ink, printhead, process parameters and kind of sample exposures.

Practical implications

The research includes practically useful information about the width, thickness, defects and resistances and their changes during a typical application for a path printed with different technological parameters.

Originality/value

This research presents the results of original empirical research on problems concerning the manufacture of paths with uniform parameters and shows how path parameters will change under exposures that may occur in a typical application. The research combines both production and application aspects.

Abstract

Purpose

The purpose of this paper is to find optimal sintering conditions of silver-based nano-inks for achieving the high electrical conductivity of the deposited layers applied on polyimide foils as well as the influence of ageing on the electrical conductivity. Therefore, the investigation in the field of silver layers deposited by inkjet printing technology is presented in this paper.

Design/methodology/approach

The four-point resistance measurements were realized for a detailed and precise analysis of the resistance of two different silver layers under different sintering conditions depending on the type of nano-ink varied about the recommended values. Highly accelerated stress tests (HASTs) were also applied as an ageing method for confirmation of the high electrical stability of the silver layers.

Findings

The results prove the strong influence of the temperature and the time of the sintering process on the sheet resistance of the investigated silver-based layers deposited by inkjet printing technology on polyimide foils. The HASTs caused significant changes in the electrical conductivity for both nano-inks presented in this paper. The existence of noticeable dependence among the resistivity, thermal treatment and ageing was proved.

Originality/value

The main benefit lays in the optimization of sintering conditions to improve the electrical conductivity of the silver layers. The paper also presents a new approach for a stability analysis of the silver layers by HASTs.

Abstract

Purpose

This paper aims to find the optimal deposition conditions for achieving the homogenous structure of the silver layers onto three types of polymeric substrates as well as on the rigid substrates. For this reason, the detailed investigation of the silver-based layers deposited at different technological conditions by microscopic methods is presented in this paper.

Design/methodology/approach

The special test pattern has been designed and deposited at different substrate temperatures by using two types of generally available silver-based nano-inks. Cross-sections and 3D profiles of the deposited silver layers have been profoundly analysed by using the optical profiler Sensofar S Neox on the generally used polymeric (PI, PET and PEN) and rigid substrates (951 and 9K7 LTCC, glass and alumina).

Findings

The results prove the strong correlation between the substrate temperature during the deposition process and the final shape of the created structure which has the a direct impact on the layers’ homogeneity. The results also prove the theory of the coffee ring effect creation in the inkjet printing technology.

Originality/value

The main benefit of this paper lies in the possibility of the homogeneity achievement of the deposited silver-based layers on the several polymeric and rigid substrates by managing the temperature during the deposition. The paper also offers the comparative study of nano-inks’ behaviour on several polymeric and rigid substrates.

Abstract

Purpose

This paper aims to find an optimal surface treatment of commonly used polymeric substrates for achieve the high adhesion of printed structures. For this reason, the investigation of substrates surfaces from different perspectives is presented in this paper.

Design/methodology/approach

The contact angle measurements as well as the roughness measurements were realised for the analysis of surface properties of investigated substrates. The impact of applied chemical agents for surface treatment onto the wettability is analysed for polyimide, polyethylene terephthalate and polyethylene naphthalene substrates.

Findings

The results prove the correlation among wettability, surface energy and work of adhesion with respect to the theoretical background. The surface treatment of polymeric substrates by chemical agents, such as acetone, toluene, ethanol, isopropyl and fluor silane polymer, has a significant impact onto the wettability of substrates which affects the final deposition process of nanoinks.

Originality/value

The main benefit of the surfaces’ investigation presented in this paper lays in surface modification by readily available chemical agents for optimising the deposition process nanoinks used in inkjet printing technology.

Abstract

Michael Brown argues that what unites the human and social sciences is their evolving character, made explicit in the concepts of “reflexivity,” “course of activity,” and “theorizing.” Once the social sciences are taken as a whole, the notion of “sociality” will allow to grasp society as ever changing, as a becoming. I shall examine the notion of sociality in the literary criticism of Lukács, Goldmann, and Adorno, three authors who consider the essay as the adequate open form of critique in times of rapid social change. Originally adopted by the young Lukács, the essay tended to be abandoned by him when elaborating the concept of critical or socialist realism as a repository of timeless cultural values. In his studies in the European realist or the soviet novel, for example, on Balzac, Stendhal, Thomas Mann, or Solzhenitsyn, the dialectical concept of social totality becomes a sum of orientations, presenting the individual writer with the moral task to choose “progress” and discard “negativity.” The social is thus narrowed to individual choice. Different from Lukács, Goldmann's literary theory defines cultural production as a matter of the social group, the transindividual subject. Goldmann was deeply marked by Lukács's early writings from which he gained notably the notion of tragedy and the concept of maximum possible consciousness—the world vision of a social group which structures the work of a writer. Cultural creation is resistance to capitalist society, as evident in the literature of absence, Malraux's novels, and the nouveau roman. In the writings of Adorno the social is lodged within the avant-garde, provided that one takes its means and procedures literally, e.g., the writings of Kafka. By formal innovation—among others the adoption of the essay, the small form, the fragment—art exercises criticism of the ongoing rationalization process and preserves the possibility of change (p. 319).

Abstract

Michael E. Brown's book, The Concept of the Social in Uniting the Humanities and Social Sciences, demonstrates that prominent attempts to account for the social dimension of human affairs rely on an unstated notion of a “course of activity,” that is diametrically opposed to the conceptualization of sociality that is presumably intended to realize it. I want to focus on the idea of a “course of activity” in order to locate his work in and clarify its importance to the development of dialectical reason from Heraclitus through Hegel and beyond. Of special importance is the bearing of his research on the critique of contemporary theories of agency and sociality, and, since considerable attention has been paid, in this regard, to the arts and humanities, some of what I will say about this refers to art and its avant-garde moments—-particularly in my work on Dada and Brown's account of two avant-garde theatrical performances. 

This chapter examines what is entailed by separating agency from individuality and what it means for the idea of a “course of activity,” (going on) and its relation to the concept of sociality. This also bears on questions of ontology, as Brown's course of activity is generative and nonrepeatable. The course of activity and nonrepeatability are linked to both avant-garde practice and theoretical notions that reframe our temporal understandings. These include the avant-garde of dada and surrealism, and the reformulations of bourgeois time of Jean Duvignaud, Walter Benjamin, Ernst Bloch, and Jean-Paul Sartre. The question raised here is that of a teleological understanding—how we link the present course of activity with future events.

Abstract

The central concern of this discussion is the relationship between belief and action. The underlying problem is how belief ‐ intellectualised as ideology ‐ affects or even determines social behaviour. As Talcott Parsons puts it, “While believing is not, ipso facto, doing, what one believes has much to do with what one does”(1).

Abstract

Purpose

To demonstrate that, at its core, Marx’s critical theory is not a critique of a mode of class exploitation that distorts modernity, undertaken from a standpoint that affirms labor, but rather one that uncovers and analyzes a unique form of social mediation and domination that structures modernity itself as a historically specific form of social life.

Methodology/approach

Critical reconstruction, interpretation, and application of Marx’s critique of political economy as developed in the Grundrisse and Capital, to the massive global transformations of the past four decades.

Findings

Marx’s critical analysis is well-suited to function as the foundation for a theory that systematically illuminates modern society in the 21st century. It is more conducive to grasping the contemporary world than traditional Marxism or most versions of post-Marxism.

Originality/value

The historical transformations of the past century suggest the central significance of a critique of capitalism for an adequate critical theory today. Such a critique must be capable of grasping the core of a social formation that is generative of a peculiar dynamic of identity and non-identity, of pointing beyond itself while reasserting itself. It indicates that the realization of the possibility of the abolition of proletarian labor is a necessary response to a deep structural crisis of capitalism.

Abstract

Purpose

To elucidate issues involved in the problem of scale, in particular the relations, analytical and dialectical, among first-person experiences of theorist and theorist’s object-complex of individual actor, group, society, motives and causes, intended and unintended effects, and so forth, as these experiences are manifest in an aesthetics of the judicial moment of perception, and enunciated as first-person accounts directly or indirectly, of third-person accounts, sometimes via explicit but usually via virtual or even vicarious second-person accounting practices.

Approach

Discussion begins with some classical formulations by neo-Kantian theorists (Simmel, Durkheim, Weber) regarding relations of “individual and society.” Brief citations of various twentieth century responses to the problem of scale follow. Attention then becomes more intensively focused on the basic problem of first-person experience and accounts with respect to the problem of scale, using Coleman’s “foundations” work as guidepost for navigating issues of effects of cognition, consciousness, and action in still mostly obscure processes of aggregation. This leads to explication of the thesis of “impossible individuality,” in present-day theoretical contexts and in the context of post-Kantian romanticism, with special attention to Hölderlin and the feeling/knowing dialectic, Benjamin’s treatment of temporality with respect to metrics of history, and the question what it means to “theorize with intent.”

Findings

The discussion ends with some tentative resolutions and several lacunae and aporia which are integral to the current face of the problem of scale (i.e., processes of aggregation, etc.).

Originality

The discussion builds upon the work of many others, with first-person illustrations.
