Graphical abstractThe separation between the double wall carbon nanotube cantilever beam tip at potential ψ1 and the substrate at potential -ψ1 as a function of ψ1 with various values of bulk ion concentration. 
Highlights► A double wall carbon nanotube was subjected to electric, osmotic, and van der Waals forces. ► Finite element analysis predicts that the sum of the electric and osmotic forces can be either repulsive or attractive. ► The nanotube deflection is not a monotonic function of the applied surface potentials, the bulk ion concentration, or the initial separation between the nanotube and the substrate. ► The pull-in voltage increases as the bulk ion concentration increases.

Research Highlights► Micro-bend of silicon photonic wire waveguide is the key for compact photonic circuits. ► Power losses in the bend waveguides are undesirable for many applications. One of the main causes of this loss is polarization conversion/cross-talk between TE and TM modes in the bend, which is mainly caused by the cross-section of the photonic wire waveguide. ► In this paper, we experimentally demonstrate that the bend loss can be reduced as much as 25% by improving the waveguide profile. We provide detailed fabrication technology behind this improvement.

Research highlights► A systematic study of SiC nanotubes(n,n)@(m,m) (3≤n≤6;7≤m≤12). ► Geometries of tubes are optimized using the functional B3LYP and the 3-21G* basis. ► Formation energy is maximum when the interlayer separation is about 3.5 Å. ► (5, 5)@(9, 9) is most stable with BE/atom and formation energy of 5.07 eV and 12.39 eV. ► All DWNTs are semiconductors, with band gaps decreasing from SWNTs to DWNTs.

Graphical abstractElectrostatic-driven positioning of gold nanoparticles was achieved in one-step during the spontaneous phase inversion of PS-b-P2VP copolymer micelles into nanorings templates. Gold arrays with tunable dimensions were produced. Research highlights► Single gold nanoparticles are guided at predetermined positions onto silicon surfaces using a simple self-assembly process. ► Gold arrays with controlled densities and periodicities are produced. ► The positioning method can be used for controlling the assembly of a large variety of nanoscale building blocks onto large scale surfaces.

Graphical abstractA novel homogenous porous layer of magnetite nano-particles (< 4 nm) was synthesized on modified charcoal granular activated carbon for extremely high efficiency of phosphate adsorption Research highlights► A novel nano-sized magnetite impregnated charcoal granular activated carbon (nFe-GAC) was developed for phosphate removal from aqueous solutions. To the best of our knowledge disclosure of such a single component porous layer of uniform iron oxide (magnetite) with unique adsorption properties was not reported before. ► A comprehensive characterization of the nFe-GAC was conducted using advanced analytical methods (such as; HR-SEM and Mössbauer spectroscopy), revealing homogenous porous layer of magnetite nano-particles (< 4 nm) immobilized onto the GAC. ► A proposed mechanism for the modification and formation of magnetite onto the GAC is specified. ► The synthesized magnetite layer showed remarkable adsorption capacity of 435 mg PO4/g Fe, which is higher by at least two orders of magnitude as compared with other adsorbents used for phosphate removal. ► A detailed kinetics analysis indicated a pseudo-second order adsorption reaction governed by diffusion within the nano-metric porous magnetite layer. ► Innovative correlation of the diffusion mechanism with the adsorption characteristics of the synthesized adsorbent is presented.
