We propose electron beam excitation assisted optical microscope, and demonstrated its resolution higher than 50 nm. In the microscope, a light source in a few nanometers size is excited by focused electron beam in a luminescent film. The microscope makes it possible to observe dynamic behavior of living biological specimens in various surroundings, such as air or liquids. Scan speed of the nano...

nanotechnology, shortened to nanotech, is the study of the controlling of matter on an atomic and molecular scale. generally, nanotechnology deals with structures sized between 1 to 100 nanometer in at least one dimension and involves developing materials or devices within that size. the use of nanotechnology in the field of pharmaceutics and drug delivery has grown over the last few years, so ...

Polymer-mediated depletion interactions were found to induce the assembly of fullerene derivates at the water-air interface into non-closed-packed 2-dimensional arrays of nanometric thickness.

Nanometric Carbid Silicon (SiC) supported monometallic and bimetallic catalysts containing Fe, Co, Ni transition metals were prepared by wet impregnation method. Multiwall carbon nanotubes (MWCNTs) were synthesized over the prepared catalysts from catalytic decomposition of acetylene at 850°C by thermal chemical vapor deposition (TCVD) technique. The synthesized nanomaterials (catalysts and CNT...

Quantum dots are promising candidates for single molecule imaging due to their exceptional photophysical properties, including their intense brightness and resistance to photobleaching. They are also notorious for their blinking. Here we report a novel way to take advantage of quantum dot blinking to develop an imaging technique in three-dimensions with nanometric resolution. We first applied t...

In this work, we report on the structure study of electrodeposited ZnO nanowires. The samples were mounted as a working electrode and the deposition was performed in a classical three electrodes electrochemical cell. For obtaining ZnO nanowires, the working electrode was a polycarbonate membrane with a random distribution of nanometric pores, gilded one side to ensure electric contact. The morp...

This work revisits capillary filling dynamics in the regime of nanometric to subnanometric channels. Using molecular dynamics simulations of water in carbon nanotubes, we show that for tube radii below one nanometer, both the filling velocity and the Jurin rise vary nonmonotonically with the tube radius. Strikingly, with fixed chemical surface properties, this leads to confinement-induced rever...

Abstract The regulation of anions and cations at the atomic scale is great significance in membrane-based separation technologies. Ionic transport techniques could also play a crucial role developing high-performance alkali metal batteries such as metal-sulfur metal-selenium batteries, which suffer from non-uniform ions (e.g., Li + or Na ) detrimental shuttling effect polysulfide/polyselenide a...
