Recent advances in the study of digital printhead-ink-substrate interaction, coupled with developments in printhead technology, have widened the tolerance for inkjet printing non-ideal fluids. A broader range of rheological profiles can now be jetted reliably, offering new commercial opportunities, particularly for di…
Sol–gel assisted spinel LiCrxNiyMn2−x−yO4 0 x 0.4 and 0 y 0.4 has been synthesized. The thermal study of the precursor was carried out by thermogravimetric and differential thermal analyses. Furthermore, the material has been subjected to X-ray diffraction, scanning electron microscopy, Fourier transform IR spectrosco…
In this paper we present an alkaline-based deinking chemistry (coded HPMA), which facilitates deinking of digital as well as conventional print media. The novel method presented here, HPMA, uses traditional alkaline deinking chemicals including sodium hydroxide and sodium silicate, but with the substitution of a readi…
The internal prestressed reinforcement is located in the interior of the prestressed concrete structure, and it is often difficult to inspect the hidden bend of the prestressed concrete structure no matter in the construction or service stage. Due to pipeline friction, anchorage retraction, instantaneous compression a…
Functional surfaces with self-cleaning property are highly desirable in many applications in the printing industry. One of the challenges in fluid ink jet systems is ink wetting and drooling onto the printhead front face. The contamination of the printhead front face leads to missing drops, wrong-sized drops, mis-dire…
Non-impact printed electronics is an expanding market with a large variety of applications where printing technology will be used to produce devices or components on glass or polymer films such as organic LED's, (organic) solar cells, displays and RFID tags. We will describe a unique and new printing technology which…
Single walled carbon nanotubes are produced in a novel apparatus by the laser-induced ablation of moving carbon target. The laser used is of high average power and ultra-fast pulsing. According to various preferred embodiments, the laser produces and output above about 50 watts/cm.sup.2 at a repetition rate above abou…
Melts based on lithium salts are applied in various branches of engineering and scientific research. This requires improved methods to search for low-melting compounds and data on phase equilibria in systems of three or more components. We developed computational and experimental method for determining the composition…
Three-armed poly(methyl methacrylate)[PMMA] was synthesized by atom transfer radical polymerization at 100 °C using benzene-1,3,5-triyl tris(4-(bromomethyl) benzoate as 3-armed initiator and a cuprous(I) bromide/2,2'-bipyridine catalytic system. The characterization of PMMA was confirmed by FT-IR, 1H-NMR, GPC, DSC, an…

Study on environmental factors influencing the urea content of cow milk in Wallonia (Belgium). The urea content in tank milk is currently assessed in Wallonia (Belgium) for all milk producers by the Comité du lait. A statistical analysis was carried out on 5,675,758 data collected over the 2002-2008 period in order to…
In this paper we investigate carbon materials prepared from different organic raw materials of vegetable nature by the method of pyrolysis. Properties of obtained carbon substances are established by the methods of impedance spectroscopy, voltamperometry, and chronoamperometry. Starting from the data of electron param…

We experimentally investigate carrier multiplication (CM) in type II CdTe/CdSe quantum dot (QD) heterostructures by the means of a simple and robust subnanosecond transient photoluminescence spectroscopy setup. Experimental conditions were set to minimize the blurring of the CM signature by extraneous effects. The ext…
Programmatic operations at the Los Alamos National Laboratory Plutonium Facility (TA-55) involve working with various amounts of plutonium and other highly toxic, alpha-emitting materials. The spread of radiological contamination on surfaces, airborne contamination, and excursions of contaminants into the operator's b…
We report a spectroscopic study about the energy transfer mechanism among silicon nanoparticles (Si-np), both amorphous and crystalline, and Er ions in a silicon dioxide matrix. From infrared spectroscopic analysis, we have determined that the physics of the transfer mechanism does not depend on the Si-np nature, find…
Five Iranian native silkworm groups: Baghdad, Khorasan Orange, Guilan Orange, Khorasan Pink, Khorasan Lemon, and 107 and 110 commercial lines (12 families from each breed) were randomly selected and reared during 2003-2005 (five generations in spring and autumn). In each family, 30 male and 30 female cocoons were indi…
