Graphical abstractAqueous dispersions of ZnS nanoparticles were stabilized with different cationic and anionic surfactants. The as-prepared nanoparticles exhibited surfactant structure dependent optical and photoluminescence properties. Highlights► Influence of cationic surfactants of different chain lengths and anionic surfactants with different head groups, as surface modifiers on synthesis of ZnS nanoparticles (NPs) in aqueous medium have been compared ► The tendency of the cationic surfactants to stabilize the ZnS NPs decreases with decreasing their hydrocarbon chain length and the anionic surfactants have been proven to be better stabilizing agents as compared to cationic surfactants of same hydrocarbon chain length ► The growth behavior of ZnS NPs, as evident from red shift in absorption spectra has been found to be quite different in all the six surfactants. In cationic surfactants, the structural transitions form metastable to stable ZnS nanocrystals due to surfactant adsorption without much affecting the average particle size has been evidenced ► In presence of anionic surfactants, the whole of absorption spectra of ZnS NPs witnessed prominent red shift with time indicating particle growth

Graphical abstract
Highlights► Stable latex particles were produced grafted with linear polyethylene imine (PEI) chains and ethanolamine, which acts as a blocking agent. ► These particles can be flocculated by nanocrystalline cellulose (NCC). ► The aggregates can be broken up by adding salt, resulting in a restabilization of the suspension

Graphical AbstractEffect of wavy carbon nanotubes on mechanical properties is investigated. It is observed that waviness significantly reduces the effective reinforcement when compared with straight long nanotubes.. Highlights► Effects of wavy carbon nanotubes on mechanical properties like elasticity and tensile strength are investigated for nanocomposites. ► Waviness significantly reduces the effective reinforcement of the nanocomposites. ► Tensile strength analysis shows a decreasing trend of the strength against the increasing the values of waviness indices.► Geometry of the RVE is also found to be affecting the strength of the Carbon Nano Tube reinforced composites.
