Number density of gold nanoparticles on the surface is varied systematically by gradually increasing either the concentration of APTES molecules in the SAM or molecular weight of grafted PAAm. The adsorption of gold nanoparticles on APTES gradient surfaces is monitored via atomic force microscopy (AFM)...
(General Physics) a dimensionless number,vρl/η, wherevis the fluid velocity, ρ the density, η the viscosity andla dimension of the system. The value of the number indicates the type of fluid flow [C19: named after OsborneReynolds(1842–1912), British physicist] ...

problem of NP colloids with higher concentrations, so that a two-dimensional joint probability density function of both the width and aspect ratio of nanorods can be retrieved, which makes the basis for the accurate determination of the MC and NC of the colloids in a large range of ...

the unicellular algaeP. subcapitatawas cultured in algal medium Woods Hole and used as the first trophic level. The algae density used was 5 × 103cells/mL in accordance with the OECD recommended guideline (OECD 201) for initial biomass of algae, and was measured using an AquaFluor fluor...
The cost of manufacturing this new material is so low, and the energy density it can store is so much higher, that the hydrogen fuel cell systems cost five times less than ordinary batteries as well as providing a much longer range—potentially enabling journeys up to around four or five ...

The number of tRNA isodecoders has increased dramatically in mammals, but the specific molecular and physiological reasons for this expansion remain elusive. To address this fundamental question we used CRISPR editing to knockout the seven-membered pheny
