Slot Die

There is a growing interest in fibers supporting optoelectrical properties for textile and wearable display applications. Solution-processed electroluminescent (EL) material systems can be continuously deposited onto fiber or yarn substrates in a roll-to-roll process, making it easy to scale manufacturing. It is important to have precise control over layer deposition to achieve uniform and reliable light emission from these EL fibers. Slot-die coating offers this control and increases the rate of EL fiber production. Here, we report a highly adaptable, cost-effective 3D printing model for developing slot dies used in automatic coating systems. The resulting slot-die coating system enables rapid, reliable production of alternating current powder-based EL (ACPEL) fibers and can be adapted for many material systems. The benefits of this system over dip-coating for roll-to-roll production of EL fibers are demonstrated in this work.

Technology Commercialisation

Purpose The purpose of this paper is to move forward the understanding of sociomaterial and processual aspects of innovation by describing and analysing actors’ disalignment processes regarding what resources to provide and strategies for resolution of disalignments during technology commercialisation. Design/methodology/approach The study is based on a longitudinal qualitative empirical case study depicting the commercialisation journey of a radical invention, intelligent paper, between the years of 1997 and 2009. The invention concerns cost-effective, high-volume and roll-to-roll production of printable optics and electronics enabling novel, intelligent functionalities on printed matter. Findings The study identifies three technology commercialisation phases which involve both destructive and constructive situations of disalignment, namely, actors’ multiplexity, punctualised actor roles and “not-programmatic” behaviours. Several strategies are utilised to resolve these, including seduction, pressuring, the introduction of new critical actors, organisational restructurings, selective silencing, career development opportunities, and joint technology development and commercialisation work. Research limitations/implications The chosen methodology excludes investigating actors’ micro-processes during technology commercialisation and the generalisability of the findings. Originality/value The study develops the understanding of the changing, multiplex and negotiated actors’ roles as well as their disalignment regarding what resources to provide during technology commercialisation. It complements perspectives of friction in innovation making and challenges the established industrial marketing and purchasing research of stable industrial networks by presenting a case in which a radical invention results in a new business network.

AbstractSimple, cost-effective roll-to-roll processes for the manufacturing of patterned conductor films have been developed. The technique involves printing proprietary masking patterns, depositing conductive material, and stripping away undesired areas. In one approach, a pattern is printed on the plastic substrate with a masking coating. Then, conductive material is deposited on the patterned substrate and the undesired areas are stripped away, leaving behind the patterned electrode structures. In another approach, a first masking pattern is printed, followed by a second masking coating which is repelled by the first masking layer and forms the negative pattern. The first masking pattern is stripped off, a conductive layer is deposited, and the second masking pattern is stripped off, leaving a high resolution conductor pattern on the web. No photolithographic exposure, development or chemical etching is needed. These processes are useful for producing rolls of electrodes with features as small as 25 microns for the roll-to-roll manufacturing of flexible display applications.

AbstractResistive random-access memory is a candidate for next-generation non-volatile memory architectures. In this study, we use flexographic roll-to-roll printing technology for deposition of the resistive layer, a printing method that allows fast and cost-effective fabrication to create non-volatile resistive memory devices. Metal-free organic polymers blends composed of poly(methyl methacrylate) (PMMA) and a surplus of poly(vinyl alcohol) (PVA) serve as the active layer. Microscopic studies of the roll-to-roll printed layers show circular domains of PMMA embedded in PVA. The influence of the PMMA content in the polymer blend is investigated with respect to the performance and reliability of the resistive memory cells. Electrical characterization reveals a retention time of at least eleven days, a Roff/Ron ratio of approx. two orders and write/erase voltages of + 1/−2 V.

Gynecologic Neoplasms

The female reproductive tract may be the site of a wide variety of benign and malignant tumors, as well as non-neoplastic tumor-like conditions, most of which can be diagnosed by light microscopic examination including special stains and more recently immunoperoxidase techniques. Nevertheless there are situations where ultrastructural examination can contribute substantially to an accurate and specific diagnosis. It is my opinion that electron microscopy can be of greatest benefit and is most cost effective when applied in conjunction with other methodologies. Thus, I have developed an approach which has proved useful for me and may have benefit for others. In cases where it is deemed of potential value, glutaraldehyde-fixed material is obtained at the time of frozen section or otherwise at operation. Coordination with the gynecologic oncologist is required in the latter situation. This material is processed and blocked and is available if a future need arises.

IBM PC compatible computers are widely used in microscopy for applications ranging from control to image acquisition and analysis. The choice of IBM-PC based systems over competing computer platforms can be based on technical merit alone or on a number of factors relating to economics, availability of peripherals, management dictum, or simple personal preference.IBM-PC got a strong “head start” by first dominating clerical, document processing and financial applications. The use of these computers spilled into the laboratory where the DOS based IBM-PC replaced mini-computers. Compared to minicomputer, the PC provided a more for cost-effective platform for applications in numerical analysis, engineering and design, instrument control, image acquisition and image processing. In addition, the sitewide use of a common PC platform could reduce the cost of training and support services relative to cases where many different computer platforms were used. This could be especially true for the microscopists who must use computers in both the laboratory and the office.

Abstract Using the iPad tablet for Augmentative and Alternative Communication (AAC) purposes can facilitate many communicative needs, is cost-effective, and is socially acceptable. Many individuals with communication difficulties can use iPad applications (apps) to augment communication, provide an alternative form of communication, or target receptive and expressive language goals. In this paper, we will review a collection of iPad apps that can be used to address a variety of receptive and expressive communication needs. Based on recommendations from Gosnell, Costello, and Shane (2011), we describe the features of 21 apps that can serve as a reference guide for speech-language pathologists. We systematically identified 21 apps that use symbols only, symbols and text-to-speech, and text-to-speech only. We provide descriptions of the purpose of each app, along with the following feature descriptions: speech settings, representation, display, feedback features, rate enhancement, access, motor competencies, and cost. In this review, we describe these apps and how individuals with complex communication needs can use them for a variety of communication purposes and to target a variety of treatment goals. We present information in a user-friendly table format that clinicians can use as a reference guide.
