ABSTRACTHere, we report the controllable fabrication of transparent conductive films (TCFs) for moisture-sensing applications based on heating-rate-triggered, 3-dimensional porous conducting networks of single-walled carbon nanotube (SWCNT)/poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate (PEDOT:PSS). How baking conditions influence the self-assembled microstructure of the TCFs is discussed. The sensor presents high-performance properties, including a reasonable sheet resistance (2.1 kohm/sq), a high visible-range transmittance (> 69 %, PET = 90 %), and good stability when subjected to cyclic loading (> 1000 cycles, better than indium tin oxide film) during processing. Moreover, the benefits of these kinds of TCFs were verified through a fully transparent, highly sensitive, rapid response, noncontact moisture-sensing device (5×5 sensing pixels).

Organic photosensor made of poly [N-9′′-heptadecanyl-2,7-carbazole-alt-5,5-(4′, 7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)] (PCDTBT) are promising candidates for bio-sensing applications. This paper investigates the optoelectronic characteristics of 4 different structures through simulation, utilizing PCDTBT as the active absorption layer. The scheme 1 is formed by placing the PCDTBT layer on top of a SiO2layer, and then interdigitated electrodes made of aluminium are placed onto PCDTBT. As to the scheme 2, the semiconductor layer is placed between an aluminium layer (bottom) and glass (top) layer coated with thick transparent interdigitated electrodes made of indium tin oxide (ITO). Regarding to scheme 3, layers from bottom to top are SiO2, cathode, PCDTBT and anode. Cathode has the same area as SiO2and PCDTBT layers, but anode covers only partial of the semiconductor. Finally, in the scheme 4, the semiconductor layer is also placed over SiO2layer but here the anode and cathode are limiting the PCDTBT layer sides, having the same area for both sides. All schemes have same volume of semiconductor. The simulations have been realized in dark conditions and under light intensities 100 mW/cm2in the wavelength range of 400-550 nm. The best results were obtained for scheme 2, organic photoconductor with Metal-Semiconductor-Metal structure. For in this scheme which is under the conditions of 2 V bias, 500 nm wavelength and 100 mW/cm2illumination, the photocurrent, the internal and external quantum efficiency obtained were 8.53 μA, 88% and 45% respectively. As a conclusion, the scheme 2 Glass/PCDTBT/Aluminium with transparent electrodes has reached high performance desirable for bio-sensing.

Abstract Carbon nanotube (CNT)-doped transparent conductive films (TCFs) is an encouraging option toward generally utilized indium tin oxide-depended TCFs for prospective stretchable optoelectronic materials. Industrial specifications of TCFs involve not just with high electrical performance and transparency but also amidst environmental resistance and mechanical characteristic; those are usually excused within the research background. Though the optoelectronic properties of these sheets require to be developed to match the necessities of various strategies. While, the electrical stability of single-walled CNT TCFs is essentially circumscribed through the inherent resistivity of single SWCNTs and their coupling confrontation in systems. The main encouraging implementations, CNT-doped TCFs, is a substitute system during approaching electronics to succeed established TCFs, that utilize indium tin oxide. Here we review, a thorough summary of CNT-based TCFs including an overview, properties, history, synthesis protocol covering patterning of the films, properties and implementation. There is the attention given on the optoelectronic features of films and doping effect including applications for sophisticated purposes. Concluding notes are given to recommend a prospective investigation into this field towards real-world applicability. Graphic abstract This graphical abstract shows the overview of different properties (mechanical, electrical, sensitivity and transportation), synthesis protocols and designing (dry and wet protocol, designing by surface cohesive inkjet-printed and the support of polymers), doping effect (general doping, metal halides, conductive polymers and graphene for transparent electrodes) and implementations (sensing panels, organic light-emitting diodes devices, thin-film transistors and bio-organic interface) of carbon nanotubes transparent conductive films.

The increased availability of High Performance Computing and Communications (HPCC) offers scientists and students the potential for effective remote interactive use of centralized, specialized, and expensive instrumentation and computers. Examples of instruments capable of remote operation that may be usefully controlled from a distance are increasing. Some in current use include telescopes, networks of remote geophysical sensing devices and more recently, the intermediate high voltage electron microscope developed at the San Diego Microscopy and Imaging Resource (SDMIR) in La Jolla. In this presentation the imaging capabilities of a specially designed JEOL 4000EX IVEM will be described. This instrument was developed mainly to facilitate the extraction of 3-dimensional information from thick sections. In addition, progress will be described on a project now underway to develop a more advanced version of the Telemicroscopy software we previously demonstrated as a tool to for providing remote access to this IVEM (Mercurio et al., 1992; Fan et al., 1992).
