Abstract Owing to their unique mechanical properties, carbon nanotubes are considered be ideal candidates for polymer reinforcement. However, a large amount of work must done in order realize full potential. Effective processing and polymers fabricate new ultra‐strong composite materials is still great challenge. This Review explores the progress that has already been made area reinforcement using nanotubes. First, properties system requirements maximize discussed. Then, main methods...
Abstract Carbon nanotubes (CNTs) demonstrate remarkable electrical, thermal, and mechanical properties, which allow a number of exciting potential applications. In this article, we review the most recent progress in research on development CNT–polymer composites, with particular attention to their electrical (conductive) properties.

We investigate theoretically the effects of generation and injection plasmonic carriers from an optically excited metal nanocrystal to a semiconductor contact or surface molecules. The energy distributions hot are dramatically different in nanocrystals with large small sizes. In nanocrystals, majority has very excitation energies, excited-carrier distribution resembles case plasmon wave bulk. For sizes smaller than 20 nm, carrier extends larger energies occupies whole region EF < ε + ℏω....
The covalent chemical functionalization of exfoliated hexagonal boron-nitride nanosheets (BNNSs) is achieved by the solution-phase oxygen radical boron atoms in h-BN lattice. This involves a two-step procedure to initially covalently graft alkoxy groups and subsequent hydrolytic defunctionalization yield hydroxyl-functionalized BNNSs (OH-BNNSs). Characterization functionalized-BNNSs using HR-TEM, Raman, UV-vis, FTIR, NMR, TGA was performed investigate both structure methodology. OH-BNNSs...

The paper reviews recent progress on chiral nanocrystal assemblies with induced optical chirality and related circular dichroism. Many natural molecules biomolecules are exhibit remarkably strong (circular dichroism) due to their amazingly uniform atomic composition in a large ensemble. It is challenging realize artificial nanoscale systems since the structure of nanostructures may not be always controlled or even known. Nevertheless, has been accomplished it main scope this review. In...
