Smart textiles, known also as e-textiles, are of great interest for the development of healthcare and wellness applications that require the embedding of electronic devices into the fabrics. Although many prototype proposals may be found in the literature, the generalization and commercialization of e-textiles is limited by the lack of cost-effective, standard fabrication processes that can be applied to a large variety of fabrics. In this contribution, we analyze the deposition of silver and carbon pastes by screen printing methods on a wide selection of daily-use textiles, to gain insight into the main features to be considered when developing cost-effective smart textiles. Results show the prospects offered by screen printing to create conductive patterns over textile and flexible materials with sheet resistances lower than 1 Ω/sq and a good repeatability in the dimensions of the patterns.

Miniaturized analytical chip devices like biosensors nowadays provide assistance in highly diverse fields of application such as point-of-care diagnostics and industrial bioprocess engineering. However, upon contact with fluids, the sensor requires a protective shell for its electrical components that simultaneously offers controlled access for the target analytes to the measuring units. We therefore developed a capsule that comprises a permeable and a sealed compartment consisting of variable polymers such as biocompatible and biodegradable polylactic acid (PLA) for medical applications or more economical polyvinyl chloride (PVC) and polystyrene (PS) polymers for bioengineering applications. Production of the sealed capsule compartments was performed by heat pressing of polymer pellets placed in individually designable molds. Controlled permeability of the opposite compartments was achieved by inclusion of NaCl inside the polymer matrix during heat pressing, followed by its subsequent release in aqueous solution. Correlating diffusion rates through the so made permeable capsule compartments were quantified for preselected model analytes: glucose, peroxidase, and polystyrene beads of three different diameters (1.4 μm, 4.2 μm, and 20.0 μm). In summary, the presented capsule system turned out to provide sufficient shelter for small-sized electronic devices and gives insight into its potential permeability for defined substances of analytical interest.

Sweep Speed

We study the sweep speed dependence of electron injection voltage in Si-Nano-Dots (Si-NDs) floating gate MOS Capacitor by using our collective tunneling model, which models the tunneling between two-dimensional electron gas (2DEG) and the Si-NDs. We clarify the sweep speed dependence of electron injection energy with a numerical calculation based on our collective tunneling model, that we developed to emulate the experiment in this system, and obtained a new insight into the origin of sweep speed dependence. We revealed that our model can reproduce the sweep speed dependence of electron tunneling. This insight is useful for designing future nano-electronic devices.

Abstract Electronic devices have become an indispensable part of our lives, while negative aspects have been reported. One downside is that reading comprehension is reduced when reading from electronic device, but the cause of this is unclear. In this study, we investigated a cause for the decline in comprehension by simultaneously measuring respiration and brain activity during reading from a smartphone medium, on thirty-four healthy individuals. Here we found that, compared to a paper medium, reading from the smartphone elicits a suppression of sigh, brain overactivity in prefrontal cortex, and decline in reading comprehension. Furthermore, a path analysis suggests that interactive relationship between sigh inhibition and overactivity in prefrontal cortex causes the comprehension decline. These findings provide new insight into a respiration-mediated mechanism of cognitive function.

Abstract Electronic devices’ widespread usage has led to a new form of pollution, known as electromagnetic (EM) pollution, causing serious problems like equipment malfunctioning and affecting its reliability. This review article presents a comprehensive literature survey on the various polycarbonate (PC)-based materials for electromagnetic interference (EMI) shielding applications comprising of PC-based composites, blend composites, foams, and more recently, multilayered architectures. Following the state-of-the-art literature available from the previous decade, it is apparent that the properties (conductivity, permittivity and permeability) of nanofiller/fillers and nanocomposite processing/fabrication techniques control the EMI shielding properties in PC-based materials. Researchers have explored a variety of fillers, but high aspect ratio carbonaceous nanofillers have gained significant attention. Through morphological modifications of PC composites, one can obtain a percolation threshold as low as 0.021 wt% of carbon nanotubes (CNTs). However, higher connectivity of conductive filler need not necessarily lead to high EMI shielding performance. Thus, detailed insight into the shielding mechanism is also highlighted. This review article will help researchers design PC-based materials with superior EMI shielding performance coupled with good mechanical stability. Graphical abstract

ABSTRACTThis paper models maximum entropy configurations of idealized gravitational ring systems. Such configurations are of interest because systems generally evolve toward an ultimate state of maximum randomness. For simplicity, attention is confined to ultimate states for which interparticle interactions are no longer of first order importance. The planets, in their orbits about the sun, are one example of such a ring system. The extent to which the present approximation yields insight into ring systems such as Saturn's is explored briefly.

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.
