Conformal SiO2 coating of sub-100 nm diameter channels of polycarbonate etched ion-track channels by atomic layer deposition
Beilstein J. Nanotechnol. 2015, 6, 472–479, doi:10.3762/bjnano.6.48
- cycles, the process provides excellent control of size adjustment of nanopores. ALD is also flexible with respect to other surface modification and suitable for applications such as selective transport of ionic species or bio species through nanochannels and the development of novel nanopore sensors
Electrical properties of single CdTe nanowires
Beilstein J. Nanotechnol. 2015, 6, 444–450, doi:10.3762/bjnano.6.45
- switching from deposition inside the nanopore to deposition on the surface. This effect was used to determine the time necessary for complete filling whereby the process can be stopped earlier. The nanowires growing from caps on the surface (indicating complete pore filling) are more difficult to harvest
Photoelectrochemical and Raman characterization of In2O3 mesoporous films sensitized by CdS nanoparticles
Beilstein J. Nanotechnol. 2013, 4, 255–261, doi:10.3762/bjnano.4.27
- steepest rise in the absorbance is observed when increasing the number of SILAR cycles from 10 to 30. The absorbance does not change notably with the further deposition of CdS, indicating that the filling of the nanopore volume in In2O3 films with CdS particles occurs mainly during the first 30 cycles of
Nanostructure-directed chemical sensing: The IHSAB principle and the dynamics of acid/base-interface interaction
Beilstein J. Nanotechnol. 2013, 4, 20–31, doi:10.3762/bjnano.4.3
- , the creation of highly active, nanopore-coated microporous extrinsic semiconductor interfaces, their ability to provide readily accessible significant light-harvesting surface areas [5], and their ability to be transformed with selective nanostructure sites, enables sensing based on efficient electron
- extrinsic semiconductors, which can be of p, p+, or n-type. The nanopore covered microporous structure is created specifically to facilitate efficient gaseous diffusion (Fickian) [6] to the highly active nanostructure-modified nanoporous coating, that acts to provide a phase matching for the subsequent
- will be the subject of future studies. Experimental As described previously [7], highly efficient nanostructure-modified interfaces on either p- or n-type PS are produced, as we generate the micro/nanoporous interface outlined in Figure 1 [3]. A hybrid etch procedure is used to generate nanopore
Characterization and properties of micro- and nanowires of controlled size, composition, and geometry fabricated by electrodeposition and ion-track technology
Beilstein J. Nanotechnol. 2012, 3, 860–883, doi:10.3762/bjnano.3.97
- schematic representation of the single-ion irradiation system is presented in Figure 1b. This GSI single-ion irradiation facility is routinely used for the production of single-nanopore membranes [30][31][32][33] and the growth of single nanowires [34][35][36]. If required for specific applications, it is
- during electrodeposition of nanowires, e.g., Cu and Bi, in single-nanopore membranes [35][36][50][51]. This pressure-sealed cell is also suitable for the growth of nanowire arrays of various materials [52][53][54][55][56][57]. Figure 5b and Figure 5c depict schematically the two deposition processes
Radiation-induced nanostructures: Formation processes and applications
Beilstein J. Nanotechnol. 2012, 3, 533–534, doi:10.3762/bjnano.3.61
- in this Thematic Series. In a somewhat analogous fashion, swift heavy ions can be used as nanopore-forming, seeding probes. When passing through thin polymer foils they leave behind a damage track, which can be further processed to form nanopores or nanochannels to be applied in biochemical analytics
Macromolecular shape and interactions in layer-by-layer assemblies within cylindrical nanopores
Beilstein J. Nanotechnol. 2012, 3, 475–484, doi:10.3762/bjnano.3.54
- charged species, in which polyelectrolyte strength, polyelectrolyte chemical structure and solution ionic strength can strongly influence deposition within the nanopores [32]. On the other hand, the confined cylindrical nanopore environment imposes a steric constraint, in which pore walls are physical
- reduced deposition is likely due to the onset of hindered diffusion within the nanopore near the pore entrance, which decreases the total amount of material being adsorbed within the porous matrix. Finally, saturation is reached at nmax, at which point electrostatic repulsion between same-charge species
- diameter for polyelectrolytes, because they formed collapsed layers. For proteins, the multilayer LbL film thickness was approximated by using the average protein diameter as an estimate. These results showed that for the cylindrical nanopore geometry, the effective volume occupied by macromolecular
Self-assembly of octadecyltrichlorosilane: Surface structures formed using different protocols of particle lithography
Beilstein J. Nanotechnol. 2012, 3, 114–122, doi:10.3762/bjnano.3.12
- OTS monolayer. (a) Contact-mode topograph, 4 × 4 µm2; (b) zoom-in view, 1 × 1 µm2; (c) corresponding cursor profile for (b). Nanopore structures of OTS were formed with particle lithography combined with contact printing. Contact-mode AFM images are shown for a sample prepared with 200 nm latex

- in the impedance of several orders of magnitude and a phase shift towards a more ohmic behavior (Figure 4). The drop in impedance indicates that at least parts of the nanopore-spanning bilayer were ruptured under these flow conditions. For input pressures below 10 mbar, the rupture of the membrane
