Ultra-fast self-assembly and stabilization of reactive nanoparticles in reduced graphene oxide films
Nanoparticles hosted in conductive matrices are ubiquitous in electrochemical energy storage, catalysis and energetic devices. However, agglomeration and surface oxidation remain as two major challenges towards their ultimate utility, especially for highly reactive materials. Here we report uniformly distributed nanoparticles with diameters around 10 nm can be self-assembled within a reduced gr...
The densification response of aluminium powder reinforced with nanometric SiC particles (50 nm) during uniaxial compaction was studied. To determine the effect of SiC nanoparticles on the compressibility of the matrix, monolithic Al powder was also examined. The effect of SiC nanoparticles on the densification mechanisms, i.e. particle rearrangement and plastic deformation, was analysed using m...
Artificially structured coatings are widely employed to minimize materials deterioration and corrosion, the annual direct cost of which is over 3% of the gross domestic product (GDP) for industrial countries. Manufacturing higher performance anticorrosive coatings is one of the most efficient approaches to reduce this loss. However, three-dimensional (3D) structure of coatings, which determines...
Aim: The aim of this study was to measure the radiopacity of seven flowable composite resins (FCRs). Methods: The radiopacity values of Tetric EvoFlow®A3 (Ivoclar Vivadent), PermaFlo®A1 (Ultradent), Filtek Supreme XT®A3 (3M ESPE), wave®A3 (SDI), StarFlow®A2 (Danville Materials), els flow®A3op (Saremco Dental AG) and SYNERGY Nano Formula®A2/B2 (Coltène Whaledent) were determined with reference t...
An experiment was conducted in CRD, which two factors were evaluated viz., different wrapping materials and levels of Silver Nano Particles taken to observe the effect shelf life cut rose. Different SNP at 10,20,30, 40 ppm along with such as- Butter paper, LDPE, aluminium foil newspaper as control used refrigerated condition. Present study concluded that roses had longest 30 NS (Nano Silver) BC...
Growing nanomaterials based consumer applications have raised concerns about their potential release into the aquatic ecosystems and the consequent toxicological impacts. So environmental monitoring of the nanomaterials in aqueous systems becomes imperative. The current study reveals the potential of Ceriodaphnia dubia (C. dubia) as a bio-indicator for aluminum oxide nanoparticles in a fresh wa...
In this project, characterization of a series of previously fabricated Aluminium clamped-clamped micro beams and cantilevers by electrical measurements in order to investigate the effects of scaling down on mechanical properties of micro/nano structures is presented. The Young’s modulus that depends on the thickness of the microstructure, residual stress and surface properties as opposed to a c...
