Isolation of cubic Si3P4 in the form of nanocrystals
Beilstein J. Nanotechnol. 2023, 14, 971–979, doi:10.3762/bjnano.14.80
- nanoparticles with a defective zinc blende structure under mild conditions through thermal annealing of hydrogenated silicon nanoparticles with red phosphorus. The synthesized Si3P4 nanoparticles were analyzed using FTIR, XRD, electron diffraction, EDX, TEM, Raman spectroscopy, X-ray fluorescence spectrometry
Renewable energy conversion using nano- and microstructured materials
Beilstein J. Nanotechnol. 2019, 10, 771–773, doi:10.3762/bjnano.10.76
- in nanoporous cobalt oxide photocathodes [7], and an approach in which silicon nanoparticles are embedded in an amorphous carbon matrix [8]. In terms of material saving, nano- and microstructured absorbers offer great potential, e.g., via ultrathin absorbers as highlighted for Sb2S3 hybrid solar
Advanced scanning probe lithography using anatase-to-rutile transition to create localized TiO2 nanorods
Beilstein J. Nanotechnol. 2019, 10, 412–418, doi:10.3762/bjnano.10.40
- anatase film. In addition, silicon nanoparticles being scraped off the AFM tip might act as nucleation sites such as other dirt particles appearing in the growth solution. However, the absence of nanorods on SiO2 indicates that the growth of rutile nanorods is not triggered by silicon nanoparticles. It
Sputtering of silicon nanopowders by an argon cluster ion beam
Beilstein J. Nanotechnol. 2019, 10, 135–143, doi:10.3762/bjnano.10.13
- near 17 keV. The dose and energy dependence of the sputtering yield was explained by the competition of the finite size effect and the effect of debris formation. Keywords: finite size effect; gas cluster ion beam; silicon nanoparticles; smoothing effect; sputtering; Introduction Etching using gas
- sputtering can include desorption of intact silicon nanoparticles similar to the process described in [32] as well as more or less complete disintegration of the silicon particles during collision with the cluster ions, analogous to disintegration by atomic bombardment [16]. Below we describe the results for
Non-agglomerated silicon–organic nanoparticles and their nanocomplexes with oligonucleotides: synthesis and properties
Beilstein J. Nanotechnol. 2018, 9, 2516–2525, doi:10.3762/bjnano.9.234
- series of works describes the synthesis of amino-containing silicon nanoparticles, so-called ORMOSIL, and their use for diagnostics and therapy [15][18]. Most often, these methods lead to the formation of nanoparticles with a diameter of 20–100 nm. Silica is particularly attractive as a functional
Hydrothermal-derived carbon as a stabilizing matrix for improved cycling performance of silicon-based anodes for lithium-ion full cells
Beilstein J. Nanotechnol. 2018, 9, 2381–2395, doi:10.3762/bjnano.9.223
- 46, 48149 Münster, Germany 10.3762/bjnano.9.223 Abstract In this work, silicon/carbon composites are synthesized by forming an amorphous carbon matrix around silicon nanoparticles (Si-NPs) in a hydrothermal process. The intention of this material design is to combine the beneficial properties of
- a measuring cylinder and tapped for 5000 times before the volume was determined. Results and Discussion Morphology and internal structure of the synthesized Si/C materials The stoichiometry of silicon nanoparticles (Si-NPs) during the hydrothermal process was calculated with the goal to obtain Si/C
Excitation of nonradiating magnetic anapole states with azimuthally polarized vector beams
Beilstein J. Nanotechnol. 2018, 9, 1478–1490, doi:10.3762/bjnano.9.139
- nonradiating modes, called “anapoles”. Here we study theoretically the excitation of such exotic anapole modes in silicon nanoparticles using structured light. Alternative illumination configurations, properly designed, are able to unlock hidden behavior of scatterers. Particularly, azimuthally polarized
- quality factor of the supported anti-resonances is quite low as well. A plasmonic nanoparticle can only provide us with a very poor (anti-)resonant spectrum to work with. So, we resort to high-index silicon nanoparticles as a platform to excite a nonradiating anapole state of magnetic type. Silicon
- nanoparticles suffer negligible losses at infrared light. Due to their high refractive index, they constitute also a good platform to host Mie resonances of magnetic type, since they can confine light and support circulating current loops inside. Now, we replace the golden sphere with a one of silicon and in
Directed deposition of silicon nanowires using neopentasilane as precursor and gold as catalyst
Beilstein J. Nanotechnol. 2012, 3, 535–545, doi:10.3762/bjnano.3.62
- with H2 plasma and the low temperature seems to avoid the formation of the silicon nanoparticles that can be found in between the NWs on the sample formed at 650 °C. Nanoparticles from “liquid bright gold” as precursor One alternative method for the deposition of thin gold films to surfaces is the use
Formation of SiC nanoparticles in an atmospheric microwave plasma
Beilstein J. Nanotechnol. 2011, 2, 665–673, doi:10.3762/bjnano.2.71
- concentration, a positive impact of the total pressure, and a negative impact of the microwave power on the mean particle size were reported. None of these relations were linear, and no parameter interactions were considered. The same authors reported the synthesis of silicon nanoparticles in a similar
