to resolve handling problem of nanoparticles, due to their small size, a new methodology of electro-spraying and freeze-drying was developed for colloidal nanoparticles of silica and titania to transform them to solid macro-scale nanoparticle assemblies.  the assemblies were then redispersed in an aqueous system to investigate the effect of formulation of original solutions and the process para...

Nanomaterials exhibit novel properties and profound attributes as an additive in asphalt binder modification. However, the application of nano-silica binders mixture modification is still limited, further research required. Along these lines, this work, with a content from 2% to 8% increment was utilized modifying bitumen type C320, which considered most conventional used Western Australia road...

Building-integrated photovoltaics (BIPVs) have gained significant attention by promising renewable electricity without concerns of additional space, environmental damage, and maintenance problems. However, silicon-based BIPVs generally limit aesthetic appearance due to their monotonous dark blue modules. In addition, maintaining performance is challenging because BIPV modules are easily contami...

In this thesis, the strength-enhancing mechanisms of dry binders in direct compression were studied. The systems investigated were binary mixtures containing various compounds and binders. Among the binders used were a series of different molecular weights of polyethylene glycol. The proposed simplified tablet model describing the fracture path in a tablet during strength testing offers an expl...

Silicon based composites are among the most promising negative electrodes for lithium ion battery applications due to their high theoretical capacities. One major drawback of silicon based anodes are their large volume changes during lithiation and delithiation. Although many efforts have been made in view of new binder materials and improved electrolytes, the resulting battery cell suffers fro...

Previous studies have demonstrated that some chronic myelogenous leukemia cells contain a macromolecular binding factor for folic acid. This binder, which previously was believed to be a single factor, has now been resolved into two distinct binding proteins. Separation of each binder was obtained by DEAE chromatography of the partially purified lysate of chronic myelogenous leukemia cells. One...

High energy density, low cost and environmental friendliness are the advantages of lithium-sulfur (Li-S) battery which is regarded as a promising device for electrochemical energy storage systems. As one of the important ingredients in Li-S battery, the binder greatly affects the battery performance. However, the conventional binder has some drawbacks such as poor capability of absorbing hydrop...

Conventional asphalt binder derived from the petroleum refining process is widely used in pavement engineering. However, asphalt binder is a non-renewable material. Therefore, the use of a co-production of renewable bio-oil as a modifier for petroleum asphalt has recently been getting more attention in the pavement field due to its renewability and its optimization for conventional petroleum-ba...

Of four protein fractions previously reported which bind corticosteroids in liver cytosol, one fraction, corticosteroid Binder II, has been found to be a major hormone receptor. It has a molecular weight of 67,000 determined by gel filtration. Binder II has an appropriate glucocorticoid binding specificity: dexamethasone > corticosterone > cortisol >> cortisone >> deoxycorticosterone and it als...
