Polyester silica nanocomposite fabrics were prepared by incorporating different concentrations of silica nano particles to the fabric by pad-dry-cure method. The prepared composite fabrics were analyzed in terms of change in their mechanical, structural as well as their functional properties. The surface morphology showed the uniform distribution of silica nano particles on fabric through SEM, ...

polyamide-66(pa66)/caco3 micro- and nano-composites were prepared using a polymer solution method at filler loading of 0, 1, 2 and 3 weight percent. nano-size of caco3 was synthesized by micro-emulsion technique. the material was characterized by xrd, sem, ftir and uv-vis techniques. xrd results of composites suggested that caco3 particles are found in the amorphous phase of the semi-crystallin...

Abstract This paper aims to study a passivation technology and process of iron nanopowder, provides basic theory experimental data for promoting the practical application nanopowder as high-efficiency catalyst in production ammonia. There are two specific objectives. The first one is provide nanometal powder device prevent nano metal from being oxidized deactivated. second method using passivat...

Hybrid lead halide perovskites have emerged as high-performance photovoltaic materials with their extraordinary optoelectronic properties. In particular, the remarkable device efficiency is strongly influenced by the perovskite crystallinity and the film morphology. Here, we investigate the perovskites crystallisation kinetics and growth mechanism in real time from liquid precursor continually ...

A new pathway to nano-sized hollow-sphere particles from six-arm star polymers with an amphiphilic core-corona structure, synthesized in a four-step-procedure by means of reversible addition-fragmentation chain transfer (RAFT) polymerization is presented, in order to achieve more stable and versatile nano-container systems, which could be applied in the fields of drug delivery or catalyst stora...

Metallic nano-particle pairs in close proximity to one another display surface-enhanced Raman scattering (SERS). Single-molecule detection has been predicted to be possible thanks to SERS. The SERS enhancement can be maximized by simultaneously increasing the curvature of the particles and bringing them into close proximity to one another. The field intensity has been predicted to increase expo...

A 3.3 kJ pulsed plasma focus device (NX2) was used to deposit magnetic CoPt nano-particles on Si (100) substrates at a low charging voltage of about 8kv. The hydrogen was used as filling gas at different gas pressures (2, 4, 6, and 8 mbar) to investigate the morphological, structural and magnetic properties of nanostructure thin films, using scanning electron microscopy (SEM), X-ray diffraction...

In general, melting process is not a common method for the production of oxide dispersion strengthened (ODS) alloys due to agglomeration and coarsening of oxide particles. However, vacuum casting process has recently been employed as a promising process to produce micro-scale oxide dispersed alloys. In this paper, we report the process and characterization of in situ formation and uniform dispe...

In order to investigate the gas separation ability of a column packed with nanozeolitic material, nano NaY zeolite was synthesized and granulated. These uniform granules packed in a chromatographic column were utilized for separation of Xe and Kr under various operating conditions. With regards to the response peaks obtained from trace injections of Xe and Kr into the column, the first and seco...

Surface layer as the outer protective coverage of bacteria and archaea are two-dimensional crystalline and symmetrical arrays of proteins that recently attract a lot of attention for biologist scientists. The surface layers of bacteria are usually 5 to 10 nm in diameter and represent highly porous protein lattices with uniform size and morphology with the pore sizes of 2 to 8 nm. The crucial an...
