Fluorescent carbon nanomaterials, especially zero-dimensional (0D) carbon nanodots (CDs), are widely used in broad biological and optoelectronic applications. CDs have unique characteristics such as strong fluorescence, biocompatibility, sun-light response, and capability of mass-production. Beyond the previous green CD obtained from harmful natural substances, we report a new type of fluid-bas...

At the annual Purdue Road School last year, a discussion of traffic paints was presented that included some general considerations, traffic-paint formulation, and traffic-paint re­ search.* Both the selection and the application of traffic paints were discussed. The research program on traffic paints of the Joint Highway Research Project was well under way at that time. The scope, purpose, and ...

−− the aim of this work is the study of the problems that arise during roll coating application of paints on steel sheets. We put in evidence the particular effects due to the non-Newtonian properties of these fluids. At speeds above a certain critical value, the flow of paint through the applicator suffers a hydrodynamical instability called ribbing, which generates a patterned interface on th...

The use of clay materials for the production of emulsion paints was investigated. Two types of clay: White tinged with Purple and Smooth clay (WSP) and Grey Brown and Coarse clay (GBC), were used for the production of Emulsion Clay Paints (ECP). Conventional Chemical pigmented Paint (CP) was also produced as a control. Atomic Absorption Spectroscopy, (AAS) was used to determine the chemical com...

An experimental study has been conducted to investigate the static and wind-on performance of two in-house-developed polymer-based pressure-sensitive paints. Platinum tetrakis (pentafluorophenyl) porphyrin and tris-bathophenanthroline ruthenium II are used as the luminophores of these two polymer-based pressure-sensitive paints. The pressure and temperature sensitivity and the photo-degradation...

This paper investigated the effect of the amine-functionalized carbon nanotubes (CNTs) on the thermomechanical properties of CNT/epoxy nanocomposites. Mechanical stirring and ultra-sonication were utilized to uniformly disperse CNTs into the epoxy matrix. Non-functionalized and amine-functionalized CNTs with different weight percentages (wt. %) were mixed into the epoxy resin. Using standard te...

epoxy – polysulfide copolymers without or with low amounts of epoxy in their structure have poor mechanical properties in oxidative curing system.to strengthen the mechanical properties of polysulfide elastomer inclusion of epoxy resin (epon828) as hard segment was studied. ft-ir spectroscopy and rheometry were used to verify the formation of epoxy-polysulfide copolymer.  results obtained from ...

Abstract The article presents results of the research on influence halloysite and its modified versions in a configuration with expandable graphite thermal stability, integrity intumescence fire-resistant paints for steel based epoxy resin ammonium polyphosphate/pentaerythritol/melamine (APP/PER/MEL) system. preliminary scanning electron microscope (SEM) analysis showed that sulfuric acid (M2) ...
