“…We obtained similar results for the preparation of polymer nanocomposites based on PA12 filled with different loading (0.1 -10 wt.%) of nanosized (average grain size of about 1 -5 nm) chromium (III) oxide [8]. It was suggested that the introduction of new fracture mechanisms, rigidity augmentation, and pronounced filler-filler interactions were responsible for the observed behavior instead of filler-polymer interactions [9][10][11][12]. The dynamics of polymer matrix changes due to changes in interactions with nanosized filler particles.…”

Broadband dielectric spectroscopy was employed to study polymer nanocomposites based on PA12 filled with different loading (0.1 -10 wt.%) of nanosized (average grain size of about 1 -5 nm) chromium (III) oxide. The experimental dielectric data were analyzed within the formalisms of complex permittivity and electric modulus. Three relaxation processes and Maxwell-Wagner-Sillars (MWS) interfacial polarizations were observed. It was found that all the relaxations were sensitive to filler contents. The presence of nanosized amphoteric chromium (III) oxide was shown to lead to the softening of the polyamide matrix that manifested in decrease of the activation energy of the α-and β-relaxation processes and glass transition temperatures. The softening of polymer matrix is the reason for the decrease in the mechanical properties of the polymer nanocomposites as compared to that of neat PA12.

“…R esearch over the last decade has established inorganic nanoparticles [1][2][3] , nanowires [4][5][6] and nanomembranes 7 as materials for high-quality electronic devices on unusual types of substrates, including plastic foils and rubber sheets 8 . A key opportunity and a realm ripe for further development and growth follows from an ability to integrate such technologies with the soft, curved contours of the human body 9 .…”

Conformable amplified lead zirconate titanate sensors with enhanced piezoelectric response for cutaneous pressure monitoring

et al. 2014

The ability to measure subtle changes in arterial pressure using devices mounted on the skin can be valuable for monitoring vital signs in emergency care, detecting the early onset of cardiovascular disease and continuously assessing health status. Conventional technologies are well suited for use in traditional clinical settings, but cannot be easily adapted for sustained use during daily activities. Here we introduce a conformal device that avoids these limitations. Ultrathin inorganic piezoelectric and semiconductor materials on elastomer substrates enable amplified, low hysteresis measurements of pressure on the skin, with high levels of sensitivity (B0.005 Pa) and fast response times (B0.1 ms). Experimental and theoretical studies reveal enhanced piezoelectric responses in lead zirconate titanate that follow from integration on soft supports as well as engineering behaviours of the associated devices. Calibrated measurements of pressure variations of blood flow in near-surface arteries demonstrate capabilities for measuring radial artery augmentation index and pulse pressure velocity.

“…[13][14][15][16][17][18] Despite their inherent excellent properties, TiO 2 NPs have several drawbacks such as agglomeration and poor interaction with organic materials. [5,19] However, these problems can be overcome through modification of these NPs by combining them with silica (SiO 2 ). Silica-titania (SiO 2 -TiO 2 ) composite NPs are interesting materials, because of their remarkable photocatalytic efficiency, durability, [1,[20][21][22][23] and suitability for use as scaffold layer in perovskite solar cells, [24] which are enhanced with respect to those of TiO 2 NPs, as SiO 2 increases the mechanical and thermal stability, adsorption ability, and specific surface area of the NPs.…”

One‐Step Direct Synthesis of SiO₂–TiO₂ Composite Nanoparticle Assemblies with Hollow Spherical Morphology

et al. 2017

View full text Add to dashboard Cite

SiO 2 -TiO 2 composite nanoparticle assemblies with or without alkyl surface modification and bearing a higher-order hollow spherical morphology were successfully synthesized by a simple, rapid, one-pot, and single-step solvothermal method using a precursor solution consisting of n-octyl-Si(OMe) 3 or Si(OEt) 4 , Ti(OiPr) 4 , o-phthalic acid, and acetic acid in methanol. The addition of acetic acid is essential for a high yield of nanoparticle assemblies with hollow spherical morphology and a high content of Si. The Si/Ti atomic ratio in the SiO 2 -TiO 2 com-
