Melt-synthesis yielded lithium-fluorohectorites (Li-hect(x)) with variable layer charge (x = 0.4, 0.6, 0.8, 1.0). Counterintuitively, both tactoid diameter and intracrystalline reactivity increased concomitantly with increasing layer charge. This way hectorites with very large diameters were obtained (d(50%) = 48 μm) that nevertheless still spontaneously delaminate when immersed into water and ...

Manmade nanoparticles range from the well-established multi-ton production of carbon black and fumed silica for applications in plastic fillers and car tyres to microgram quantities of fluorescent quantum dots used as markers in biological imaging. As nano-sciences are experiencing massive investment worldwide, there will be a further rise in consumer products relying on nanotechnology. While b...

Carbon−based nano−conductive silicone rubber is a kind of composite conductive polymer material that has good electrical and thermal conductivities high magnetic flux. It application prospects for replacing most traditional materials, but its mechanical tensile strengths are poor, which limit applications. In this study, carbon fiber (CF), graphene (G) nanotubes (CNT) used as fillers to prepare...

Volume fraction and spatial repartition of fillers impact the physical properties of rubber. Extended percolating networks of nano-sized fillers significantly modify the macroscopic mechanical properties of rubbers. Random models that describe the multiscale microstructure of rubber and efficient Fourier-based numerical algorithms are combined to predict the material’s mechanical properties. Fr...

The nano-sized silica fillers reinforced poly(ether ether ketone) (PEEK) composites were fabricated by means of compression molding technique. he nano-sized silica, measuring 30 nm in size, was firstly modified by surface pretreatment with stearic acid. The performances and properties f the resulting PEEK/SiO2 nanocomposites were examined in terms of tensile loading, hardness, dynamic mechanica...

This study investigated the effect of adding bioactive glass 45S5 (BG) different particle sizes to dental composite on resin polymerization and shrinkage stress formation. Commercial flowable was mixed with either 15 wt% BG fillers (nanometric, micrometric, or hybrid BG) inert barium glass. Real-time linear were recorded, degree conversion measured using FTIR spectroscopy. The commercial (unmod...

In this paper electrical characteristics of various kinds of multiple-gate silicon nanowire transistors (SNWT) with the channel length equal to 7 nm are compared. A fully ballistic quantum mechanical transport approach based on NEGF was employed to analyses electrical characteristics of rectangular and cylindrical silicon nanowire transistors as well as a Double gate MOS FET. A double gate, tri...

Abstract Superpositions of paraxial laser beam modes to generate atom-optical lenses based on the optical dipole force are investigated theoretically. Thin, wide, parabolic, cylindrical and circular atom lenses with numerical apertures much greater than those reported in the literature to date can be synthesized. This superposition approach promises to make high quality atom beam imaging and na...

Abstract The ratio of poly(lactic acid) (PLA), poly(butylene adipate- co -terephthalate) (PBAT), and calcium carbonate (CaCO 3 ) fillers in PLA/PBAT/CaCO composites was set at 90/10/5, 70/30/5, 30/70/5. effect nano- micro-CaCO on the melting crystallization performance investigated by differential scanning calorimetry. PLA related to PBAT ratio, cooling rate, CaCO particle size composites. Nano...
