“…Ni nanocrystallites in films used as a substrate in CVD process play the role of a catalytic agent in the carbon nanotube creation. Effect of Nickel precursor on the growth of carbon nanotubes obtained by CVD method has been confirmed in numerous works [30][31][32][33][34]. The theoretical discussions in many papers [14,[35][36][37] confirm that the nanotube growth starts from fullerene particle.…”

Abstract:The work presents the results of the scanning electron microscopy (SEM) and Raman spectrometry studies of carbonaceous nanostructures containing nickel nanocrystallites. The films were obtained using a twostep method. In the first phase the Physical Vapour Deposition (PVD) method was applied, whereas in the second Chemical Vapour Deposition (CVD) method was used. The paper presents results for samples with various Ni content obtained with different parameters of the two-phase technological process. The research confirms that the thin films obtained by PVD method contain Ni nanocrystallites distributed in a carbonaceous matrix. The matrix is composed of various carbon allotropes (amorphous carbon, graphite, fullerene). The thin films made by CVD method make a matrix when multiwalled, carbonaceous nanotubes are obtained. Depending on the technological process parameters of each phase, we obtain multiwall nanotubes with a various degree of defects. PACS (

“…There are three main steps in the synthesis process. 76 The first step is the cracking step, where the energy source is used to crack the gas phase molecule into atomic carbon. The second step is the diffusion step, during which cracked atomic carbon diffuses toward the substrate.…”

Glioblastoma multiforme (GBM) is the most common and most aggressive malignant primary brain tumor in humans. Current GBM treatment includes surgery, radiation therapy, and chemotherapy, sometimes supplemented with novel therapies. Despite recent advances, survival of GBM patients remains poor. Major challenges in GBM treatment are drug delivery across the blood–brain barrier, restriction of damage to healthy brain tissues, and limitation of resistance to therapies. This article reviews recent advances in the application of magnetic nanoparticles (MNPs), gold nanorods (GNRs), and carbon nanotubes (CNTs) for hyperthermia ablation of GBM. First, the article introduces GBM, its current treatment, and hyperthermia as a potential modality for the management of GBM. Second, it introduces MNPs, GNRs, and CNTs as inorganic agents to induce hyperthermia in GBM. Third, it discusses different methodologies for synthesis of each inorganic agent. Finally, it reviews in vitro and in vivo studies in which MNPs, GNRs, and CNTs have been applied for hyperthermia ablation and drug delivery in GBM.

“…The increase in demand for these nanostructures is mainly attributed to their unique electrical, optical, magnetic, thermal, mechanical and chemical properties [5,9]. Several fabrication methods including electrochemical deposition [10], electroless deposition [11], sol-gel [12], chemical vapour deposition (CVD) [13,14], and atomic layer deposition (ALD) [15] have been utilized to deposit 1D carbon [13,14], metal [15], oxide [12], semiconducting [12], polymer [10], and hybrid [11] nanostructures. However, the CVD and ALD processes require high deposition temperatures, typically ranging between 500 °C and 900 °C.…”

Morphology of electrospun poly(ethylene oxide) ultra-fine fibres with incorporated MoO3 nanoparticles

N-type semiconducting molybdenum trioxide (MoO3) nanoparticles embedded in polyethylene oxide (PEO) polymer ultra-fine fibres were deposited directly onto silicon substrates using an electrospinning technique. The effects of different MoO3/PEO concentrations as well as electrospinning parameters on the fibre morphologies were examined. Experimental results show that embedding nanoparticles and electrospinning onto small areas can be achieved without use of solvents or transfer of the deposited nanostructures. This approach offers a cost effective fabrication method to produce a diverse range of multifunctional materials for many applications including electronics, mechanical enhancement, drug delivery and gas sensing.
