The tributylphenyltin (TBPT)-encapsulated resorcinol (R)-formaldehyde (F) sol was prepared inside the micelles of cetyltrimethylammonium bromide (CTAB). This core-shell-type sol was polymerized and further carbonized to obtain nanosized Sn-encapsulated spherical hollow carbon. The size of spherical hollow carbon and Sn metal particles was controllable by changing the R/CTAB or TBPT/CTAB mole ra...

Nanomaterials have attracted considerable attention during the last two decades, due to their unusual electrical, mechanical and other physical properties as compared with their bulky counterparts. The mechanical properties of nanostructured materials show strong size dependency, which has been explained within the framework of continuum mechanics by including the effects of surface stress. The...

GeO2/Ge/C anode material synthesized using a simple method involving simultaneous carbon coating and reduction by acetylene gas is composed of nanosized GeO2/Ge particles coated by a thin layer of carbon, which is also interconnected between neighboring particles to form clusters of up to 30 μm. The GeO2/Ge/C composite shows a high capacity of up to 1860 mAh/g and 1680 mAh/g at 1 C (2.1 A/g) an...

This thesis describes the feasibility of utilizing an electric field for separation of charged species through a membrane. This forms the central theme in all chapters. The membranes can be regarded as an interconnect between two separate liquids. By applying an external electric field over the interconnect it is possible to transport charged species from one liquid to the other. In this chapte...

Mesoporous, micro/nanosized TiO2/C composites with uniformly dispersed TiO2 nanoparticles embedded in a carbon matrix have been rationally designed and synthesized. In brief, TiO2 precursor was infiltrated into the channels of surface-oxidized mesoporous carbon (CMK-3) by means of electrostatic interaction, followed by in situ hydrolysis and growth of TiO2 nanocrystallites, resulting in ultrafi...

Direct-Writing （DI） or Direct-Ink-Writing （DIW） technique facilitates the fabrication of three-dimensional （3D） colloidal structures through layer-by-layer deposition rheological controlled particle-dispersed-inks. This offers superiority due to free choices particles. Various types particles including nanomaterials such as CNTs and graphene have been printed successfully by DI technique. In ad...

An analytical form of the Raman shift dependence on size of nanocrystals is presented. Based on the hard confinement model, it works in those cases where the average phonon curve shows a quadratic dependence on the phonon quasi-momentum in the range of interest. PACS : 78.67.Bf, 78.30.-j, 78.30.Am, 36.20.Ng Raman spectroscopy is an important tool in gathering information about molecular and cry...

The self-assembly of molybdate building units in the presence of Fe(II) and V(IV) produces the first mixed-spin heterometal keplerate-type clusters displaying ferrimagnetic interactions.

Understanding and controlling the mechanisms that determine the efficiency of photoelectric devices is of fundamental importance in the quest for efficient and clean sources of energy. Thermodynamically speaking, these devices are driven by the temperature difference between a hot reservoir sun, temperature Ts and a cold reservoir earth, ambient temperature T . Therefore, like any heat engine, ...
