Experimental investigation of usage of POE lubricants with Al2O3, graphene or CNT nanoparticles in a refrigeration compressor
Beilstein J. Nanotechnol. 2023, 14, 1041–1058, doi:10.3762/bjnano.14.86
- refrigeration compressors are metal oxides and carbon-based nanoparticles [11][12]. It is emphasized that both kinds of nanoparticles have positive effects on system performance. Krishnan et al. [13]. examined the effects of addition of metal oxide nanoparticles of Al2O3, SiO2, ZrO2, and carbon-based
Electrostatic force microscopy for the accurate characterization of interphases in nanocomposites
Beilstein J. Nanotechnol. 2018, 9, 2999–3012, doi:10.3762/bjnano.9.279
- film [38][44]. Step C: PS + 50 nm SiO2 + 50 nm Al2O3 and PS + 100 nm Al2O3 (SiO2 interphase detection) In step C, the comparison concerned the EFM response of PS + 50 nm SiO2 + 50 nm Al2O3 and PS + 100 nm Al2O3 samples (Figure 5, step C). As observed in step B, while the average topography profiles
- prepared for this study to produce an electrostatic model of a nanodielectric (particle + interphase + matrix). They were based on spherical PS particles deposited on a metallic substrate. Al2O3, SiO2 and PVAc were used to cover the particles and to mimic either the interphase layer or the matrix layer
- between the theoretical and the actual Al2O3, SiO2, and PVAc thickness [38]. 2D axisymmetric dimensions were used in accordance with model symmetry when measuring the force at the top of the particle/interphase assembly. The probe was biased at 5 V in DC, while the substrate was grounded. Only the z
Parylene C as a versatile dielectric material for organic field-effect transistors
Beilstein J. Nanotechnol. 2017, 8, 1532–1545, doi:10.3762/bjnano.8.155
- insulating material. The capacitance is determined by the dielectric permittivity (ε) and the thickness of the insulating layer. Currently, two types of dielectric materials are commonly employed in transistor design and construction, either inorganic metal oxides (such as Ta2O5, Al2O3, SiO2) or organic
Tunable white light emission by variation of composition and defects of electrospun Al2O3–SiO2 nanofibers
Beilstein J. Nanotechnol. 2015, 6, 313–320, doi:10.3762/bjnano.6.29
- Avenue, 639798, Singapore 10.3762/bjnano.6.29 Abstract Composite nanofibers consisting of Al2O3–SiO2 were prepared by electrospinning in combination with post-calcination in air. X-ray diffraction, scanning electron microscopy, and transmission electron microscopy were used to investigate the
- materials. Keywords: Al2O3–SiO2; defects; electrospinning; nanofibers; photoluminescence; white light emission; Introduction During the last decade, nanoscale SiO2 has been intensely investigated as a new silicon-based light-emitting material. Its wide photoluminescence (PL) band ranges from the UV to red
- ]. From the above referenced work, it can be seen that the mechanism of this defect-dominant PL still remains ambiguous, and it is also a challenge to obtain the desired white luminescent material by control the different defects. Moreover, to date, few studies have reported on Al2O3–SiO2 nanocomposites
Functionalization of vertically aligned carbon nanotubes

- [Al2O3·SiO2·2H2O] [22]. The schematic representation of imogolite is shown in Figure 1. The gas adsorption data of N2, CO2, and CH4 concluded that imogolite possesses an inner-pore diameter of 1 nm [23]. The wall structure of imogolite comprises a layer of gibbsite on the outer wall, and a layer of
