Solution-processed photodetectors from colloidal silicon nano/micro particle composite.
We demonstrate solution-processed photodetectors composed of heavy-metal-free Si nano/micro particle composite. The colloidal Si particles are synthesized by electrochemical etching of Si wafers, followed by ultra-sonication to pulverize the porous surface. With alkyl ligand surface passivation through hydrosilylation reaction, the particles can form a stable colloidal suspension which exhibits...
متن کاملColloidal micro- and nano-particles as templates for polyelectrolyte multilayer capsules.
Colloidal particles play an important role in various areas of material and pharmaceutical sciences, biotechnology, and biomedicine. In this overview we describe micro- and nano-particles used for the preparation of polyelectrolyte multilayer capsules and as drug delivery vehicles. An essential feature of polyelectrolyte multilayer capsule preparations is the ability to adsorb polymeric layers ...
متن کاملDiffusion through colloidal shells under stress.
The permeability of solids has long been associated with a diffusive process involving activated mechanism as originally envisioned by Eyring. Tensile stress can affect the activation energy but definitive experiments of the diffusion rate of species through a stressed solid are lacking. Here we use core-shell (liquid core-solid shell) colloidal particles that are sensitive to osmotic pressure ...
متن کاملFacile and economic method for preparation of nano-colloidal Silica with controlled size and stability
This study is focused on synthesis of nano-colloidal silica via alkaline water glass solution. Sodium ions of water glass were removed by cation exchanging in a resin column to obtain the silicic acid which was titrated to the solution of sodium silicate. Concentration of the colloidal silica and pH value of the solutions were controlled using different concentrations of alkaline sodium silicat...
متن کاملInhibition of selectin binding by colloidal gold with functionalized shells.
Gold colloids with terminally functionalized sulfated thiol shells were found to bind to P- and L-selectins with IC(50) values in the picomolar range; branched acyclic epitopes show the highest affinity, whereas a sulfated carbohydrate mimetic provides the best selectivity.
