Screen printing originated in China during the Song dynasty (960-1279 CE) and is used today commercial artistic applications. The presented research project describes development of a screen-printing product for studio art improvement paper properties from laboratory small 12-inch machine development, followed by semi production at speed 128 ft/min on 48-inch final paper, showed an throughout p...

Word of the CSCL 2011 conference in Hong Kong spread around the world instantaneously, thanks to computer support of this intensive community collaborative learning effort. Tweets, blogs, Facebook postings, Flicker pictures, and video streaming accompanied the many face-to-face presentations and informal interactions during the pre-conference, main conference, and post-conferences in early July...

The use of thick films becomes more and more important in particular for electronic and microelectronic applications. The term “thick film” does not relate so much to the thickness of the film but more to the kind of deposition. Thick films are made by low-priced processes such as doctor (dr) blading, screen-printing, or spraying methods, etc. The preparation of thick films of ceramic material ...

Single-use aluminum foil-based laser desorption/ionization (LDI) target plates have been developed for mass spectrometry (MS) analysis and provide detection results comparable to those of commercial stainless steel plates while offering a convenient way to avoid the time-consuming surface cleaning process. Additionally, arrays of TiO(2) nanoparticle spots are coated on the foil either by screen...

A comprehensive experimental investigation has been carried out into the role of film thickness variation and silver material formulation on printing capability in the screen printing process. A full factorial experiment was carried out where two formulations of silver materials were printed through a range of screens to a polyester substrate under a set of standard conditions. The materials re...

This contribution presents a fuzzy method for a particular kind of pixel classification. It is one of the most important results of the development of an inspection system for a silk-screen printing process. The classification algorithm is applied to a reference image in the initial step of the printing process in order to obtain regions which are to be checked by applying different criteria. T...

Abstract. In this paper a fuzzy method for pixel classification is proposed. It is one of the most important results of the development of an inspection system for a silk-screen printing process. The classification algorithm is applied to a reference image in the initial step of the printing process in order to obtain regions which are to be checked by applying different criteria. Tight limitat...

An inkjet printing method is described to fabricate hydrogen peroxide (H(2)O(2)) sensors. Insoluble Prussian blue (PB) nanoparticles were dispersed in aqueous solvent, and were printed on screen printed carbon electrodes with a piezoelectric inkjet printer for H(2)O(2) detection. The electrochemical behavior of the printed sensors was studied by using cyclic voltammetry and chronoamperometry....

The Laboratoire d'Electrochimie Physique et Analytique (LEPA) has moved to the new Energypolis campus in Sion. This laboratory is involved in energy research in particular by studying charge transfer reactions at soft interfaces and developing interfacial redox electrocatalysis, by pioneering the concept of photo-ionic cells and by integrating redox flow batteries for the production of hydrogen...
