Polymer membranes with two-dimensionally arranged pores derived from monolayers of silica particles
This paper describes a simple method to prepare porous polymer membranes with closely packed two-dimensionally arranged pores ranging from approximately 20 to 1000 nm diameter. Mixtures ofExpand

Dendrimer-Encapsulated Pt Nanoparticles : Synthesis , Characterization , and Applications to Catalysis
[14] H. Baltes, M. Schwendler, C. Helm, R. Heger, W. A. Goedel, Macromolecules 1997, 30, 6633. [15] One can calculate the thickness of the monolayer before transfer by dividing the surfaceExpand
A simple theory of particle-assisted wetting
Adsorption of solid particles to a fluid/fluid interface can reduce the total interfacial energy of a system of three fluid bulk phases in such a way that the particles induce the wetting of aExpand
Polymer microsieves manufactured by inkjet technology.
Liquid sessile drops can be used as sacrificial templates for the creation of pores in polymeric microsieves. Using inkjet printing, we deposit sessile drops of a water-based liquid onto aExpand
Polymer−Silica Hybrid Monolayers as Precursors for Ultrathin Free-Standing Porous Membranes
Forty-nanometer-thin free-standing membranes with 55-nm-wide pores have been prepared via Langmuir−Blodgett transfer. Hydrophobized silica colloids and polyisoprenes with quaternary ammoniumExpand
Josephson junctions defined by a nanoplough
We define superconducting constrictions by ploughing a deposited Aluminum film with a scanning probe microscope. The microscope tip is modified by electron-beam deposition to form a nanoplough ofExpand
Electronic properties of electrolyte/anodic alumina junction during porous anodizing
Abstract The growth of porous oxide films on aluminum (99.99% purity), formed in 4% phosphoric acid was studied as a function of the anodizing voltage (23–53 V) using a re-anodizing technique andExpand
Influence of particle hydrophobicity on particle-assisted wetting.
The surface properties of silica particles significantly influence their efficiency in particle-assisted wetting. A series of small particles of controlled surface hydrophobicity was mixed with aExpand
Effect of silicon fertilizers on silicon accumulation in wheat
The effect of fertilization with silicon (Si) compounds on accumulation of Si in wheat (Triticum aestivum L.) has been studied. Wheat plants were grown under identical growing conditions, butExpand
