Plasmonics based sensors have been a prominent area of research. Plasmonics based sensors are widely used in bio sensing and many other applications. The basic mechanism in which these sensors operate is that there are metal nano particles that are separated by a very small distance between them. The dimensions of these nano particles is much smaller than the incident light [1]. For sensing pur...

nano technology has a large number of applications in different fields of science and technology. nano particle are the tiny particles which are being used in upcoming technology due to their small size and high capability. the properties of nanoparticles depend largely on their synthesis procedures. there are different methods for the synthesis of nano particles using different conditions. in ...

proper feeding is necessary to have appropriate growth, health and also to increase resistance to inappropriate condition such as stressors and diseases. therefore mineral and vitamin supplements are added to fish diet to improve its growth and health. food supplements have different roles in diet. these cause better food metabolism, higher hardness and strength of bones, better ionic exchanges...

To substitute for petroleum, Fischer-Tropsch synthesis (FTS) is an environmentally benign process to produce synthetic diesel (n-paraffin) from syngas. Industrially, the synthetic gasoline (iso-paraffin) can be produced with a FTS process followed by isomerization and hydrocracking processes over solid-acid catalysts. Herein, we demonstrate a cobalt nano-catalyst synthesized by physical-sputter...

The Class F fly ash has been subjected to high energy ball milling and has been converted into nanostructured material. The nano structured fly ash has been characterized for its particle size by using particle size analyzer, specific surface area with the help of BET surface area apparatus, structure by X-ray diffraction studies and FTIR, SEM and TEM have been used to study particle aggregatio...

This work gives sequence to the study on the measurement of the electrostatic charges in aerosols. The particle charge classifier developed for this purpose and presented in the previous paper (Marra and Coury, 2000) has been used here to measure the particle charge distribution of a number of different aerosols. The charges acquired by the particles were naturally derived from the aerosol gene...

Within the mode-coupling theory (MCT) of glass transition, we reconsider numerical schemes to evaluate MCT functional. Here propose nonuniform discretizations wave number, in contrast standard equidistant grid, order decrease number grid points without losing accuracy. We discuss detail how integration scheme on new grids has be modified from Riemann integration. benchmark our approach by solvi...

this study was conducted to enhance the antimicrobial properties and water absorption of sanitary papers. for this purpose, montmorillonite nano clay with bentonite brand (has a layered structure in which its thickness is nano metric), was processed with homogenizer to achieve a stable colloidal system with nanometer dimensions of particle size. then, different weight levels of raw and homogeni...

Abstract A modified phase-field model is presented to numerically study the dynamics of flowing foam in an obstructed channel. The bubbles are described as smooth deformable fields interacting with one another through a repulsive potential. strength lies its ability simulate foams wide range gas fraction. motion, composed about hundred two-dimensional elements, was analyzed for fractions rangin...
