This project has been performed at Scania and it is a pre-study for a standard description of binders in cables harness in different environments in the truck. The different environmental zones are the cab, chassis and power train. Different zones in the truck have different requirements such as temperature, chemicals…
The anti-frictional properties of materials of the metal – graphite containing lubricant component systems were discussed.
Many pharmaceutical compounds being developed in recent years are poorly soluble in water. This has led to insufficient oral bioavailability of many compounds in vitro. The amorphous formulation is one of the promising techniques to increase the oral bioavailability of these poorly water-soluble compounds. However, an…
Many proteins have an innate ability to self-assemble into fibrous structures known as amyloid fibrils. From a material science perspective, fibrils have several interesting characteristics, including a high stability, a distinct shape and tunable surface properties. Such structures can be given additional properties…
The formation of nanoscale structures in the photosensitive glass that opens up new possibilities in the preparation of glasses for special purposes. Change in the conditions of synthesis of glasses, their composition, the introduction of activators demonstrated the ability to create modern optoelectronic systems. As…
Diese Doktorarbeit handelt von Oberflächen die, als Unterlage für photochrome Moleküle als Schalter die größtmögliche Eignung vorweisen. Bei der Untersuchung wurden zwei unterschiedliche Klassen von Schalter-Molekülen verwendet, die Klasse der Azobenzole und die Klasse der Spiropyrane. Mit diesen Molekülen werden drei…
The morphology may significantly influence the properties and applications of materials, thus the ability to tune the structure, size, and shape of inorganic materials is an important goal in obtaining nanomaterials with novel properties. A novel and facile synthesis route for the manufacture of porous Co 3 O 4 is rep…
Nvestigation of heat production in damper polyurethane massif working under slide in regime of dynamic load is presented in the article. Temperature selection rationale of polyurethane massif damper as main performance criterion is presented. Description of experimental plant and loading fixture for investigation of q…
The stability of the anti-asthmatic drug pemirolast potassium was investigated under different stress conditions, including hydrolysis (acid and alkali), heat, light and oxidation as recommended by the ICH guidelines.
Protection and controlled release of chemicals through encapsulation have been extensively used in daily applications such as drug delivery, food processing, enzyme stabilization, and chemical storage. A significant need for further development in this area is to reduce the capsule size and to obtain more predictable…
Biogas, which generated from renewable sources can be used as a sustainable energy to achieve resourceful targets of biofuel for internal combustion engines. This process can be achieved in combined absorption and adsorption chemical way. This method can be employed by aqueous solutions of calcium hydroxide, activated…
In the present work, we report the effect of Te deposition onto As2Se3 film which affects the optical properties. The Te/As2Se3 film was illuminated with 532 nm laser to study the photo induced diffusion. The prepared As2Se3, Te/As2Se3 films were characterized by X-ray diffraction which show a completely amorphous nat…
The acrylate copolymer emulsion with core-shell structure was successfully prepared via pre-emulsified semi-continuous seeded polymerization using SDS and OP-10 as compound emulsifier, and methyl methylacrylate (MMA), butyl acrylate (BA) and dodecafluoroheptyl methacrylate (DFMA) as main monomers. SEM and OCA were use…
The TC4 titanium alloy were deformed at 800, 2mm/s with various extrusion loops by a new sever plastic deformation method-Continuous Various Cross-section Recycled Extrusion, then the microstructure and microhardness of the specimen along the radial, the maximum deformation force in each extrusion procedure were also…
Specifically, the project involves the development of a diversified array of nanostructured gas-sensors comprised of selectively, novel surface-functionalized carbon nanotubes (for analyte selectivity by virtue of functionality). Harnessing carbon nanotubes with various electron withdrawing and donating groups help in…
Dentro del abanico de tecnicas de produccion de membranas polimericas, se encuentra aquella que se basa en una de las tecnicas generales de procesado de materiales polimericos termoplasticos con mayor implantacion en el mercado industrial, como es la extrusion. En este sentido, es posible fabricar este tipo de membran…
Alongside the CMS Pixel Luminosity Telescope (PLT) – installed last month (see here) – lie diamond detectors. No ordinary gems, these lab-grown diamonds will be playing a vital role in Run 2: differentiating signals from collision products with those from the beam background. The BCM detector's green "c-shaped" printe…
A series of branched styryl derivatives based on 1, 3, 5-triazine have been studied by time-resolved fluorescence anisotropy method to study the intramolecules interferaction between branches. The obtained results further confirmed the TPA enhancement mechanism, the anisotropy of trimer shows faster decay and small re…
Liquid natural rubber (LNR) with molecular weight of lower than 105 and shorter polymeric chain than natural rubber was prepared. LNR was then hydrogenated via diimide reduction by oxidation of hydrazine hydrate with hydrogen peroxide. The unsaturated units of the rubber were converted into saturated hydrocarbon to st…
Rare-earth permanent magnets are used extensively in numerous technical applications, e.g. wind turbines, audio speakers, and hybrid/electric vehicles. The demand and production of rare-earth permanent magnets in the world has in the past decades increased significantly. However, the decrease in export of rare-earth e…
