Three‐dimensional Antimony Sulfide Based Flat Optics
Advanced Functional Materials, EarlyView.This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.

Characteristics of blended cements containing nano-silica
HBRC Journal, 2013 AbstractThe aim of the present work is to evaluate the effect of nano-silica (NS) on physico-chemical, compressive and flexural strengths of OPC-granulated slag blended cement pastes and mortars. Different mixes were made with various amounts of NS, OPC and granulated blast-furnace slag (GBFS) and hydrated for 3, 7, 28 and 90days.

Tough nanoparticle-modified polymers
, 2010 A crosslinked epoxy polymer has been modified by the addition of nano-silica particles. The particles were introduced via a sol-gel technique which gave a very well dispersed phase of nano-silica particles which were about 20 nm in diameter.

Chemical Resistance of Nano Silica Added Concrete
International Journal of Innovative Technology and Exploring Engineering, 2019 This study investigated the effects of nano silica on acid and sulphate resistance of concrete. The changes in mass and compressive strength of the concrete specimens for different immersion periods were determined. It was observed that, M 30 grade concrete produced with 0 %, 1 %, 2 %, 3 % nano silica have shown mass loss of 11.24 %, 9.01 %, 5.10 % and
