The objective of this study was to investigate a technique to obtain inorganic nanoparticle impregnated wood fiber reinforcement in the thermoplastic matrix. Inorganic nanoparticulates as a function of void filler and interfacial compatibilizer were generated through the chemically reconstruction method using two different ionic salts (CaCh to Na2C03). The longer reaction time of two ionic salt...

A peptide sequence N(3)-GVGV-OMe (G: glycine; V: valine) was attached to a benzene 1,3,5-tricarboxamide (BTA) derivative via"click chemistry" to afford a C(3)-symmetric artificial oligopeptide. The key feature of this oligopeptide is that the binding sites (triazole groups formed by click reaction) are located at the center, while the three oligopeptide arms with a strong tendency to assemble a...

Introduction CdSe-P3HT (poly(3-hexylthiophene))) nanocomposites are studied for their application in hybrid solar cells. Semiconductor inorganic/organic hybrid solar cells offer many advantages relative to their non-hybrid counterparts. They have the advantages of conjugated polymers such as light weight, flexibility, abundance of resources, the potential for roll-to-roll and non-vacuum process...

We confirmed the influence of ZnO nanoparticle size and residual water on performance of all inorganic perovskite solar cells. By decreasing the size of the ZnO nanoparticles, the short-circuit current density (Jsc) and open circuit photovoltage (Voc) values are increased and the conversion efficiency is improved. Although the Voc value is not affected by the influence of residual water in the ...

We developed an unconventional route to produce uniform and intimately contacted semiconducting organic-inorganic nanocomposites for potential applications in thermoelectrics. By utilizing amphiphilic star-like PAA-b-PEDOT diblock copolymer as template, monodisperse PEDOT-functionalized lead telluride (PbTe) nanoparticles were crafted via the strong coordination interaction between PAA blocks o...

Over the last decade there has been significant progress in the synthesis of inorganic and hybrid inorganic-organic nanoparticles in solution. Optimizing the synthesis conditions is often dependent on structural characterization of the nanoparticles. Transmission Electron Microscopy (TEM) provides a method for structural characterization that provides both high-resolution details of individual ...

Organic-inorganic membranes were obtained by stepwise modification of poly(ethyleneterephthalate) track membrane with nanoparticles of zirconium hydrophosphate. The modifier was inserted inside pores of the polymer, a size of which is 0.33 μm. Inner active layer was formed by this manner. Evolution of morphology and functional properties of the membranes were investigated using methods of poros...

The unique, well-defined tubular structure of carbon nanotubes (CNTs) continues to attract interest. CNTs are fascinating materials for basic scientific research with the potential for several promising applications in catalysis, electronic devices and chemical biology. In recent years, many efforts have led to the development of versatile methods to modify CNTs to obtain derivatives with more ...

The photocatalytic coatings were prepared via incorporating the modified titania nanoparticles into epoxy-based inorganic-organic hybrid coatings. Titania nanoparticles were first synthesized from tetra-n-butyl titanate using sol-gel methods by two different calcination treatments, i.e., in mild condition (80°C) and 500°C. The formed anatase nanoparticles were further modified as Titania-Silica...
