There has been renewed interest in solar concentrators and optical antennas for improvements in photovoltaic energy harvesting and new optoelectronic devices. In this work, we dielectrophoretically assemble single-walled carbon nanotubes (SWNTs) of homogeneous composition into aligned filaments that can exchange excitation energy, concentrating it to the centre of core-shell structures with rad...

LLE Review, Volume 71 113 The current target-shell material for direct-drive experiments on OMEGA is a low-density hydrocarbon polymer fabricated using a low-pressure plasma polymerization process. This material meets the immediate requirements for an inertial confinement fusion (ICF) target shell: low density; smooth surfaces (outer and inner); spherical and concentric; and the capability of b...

About one third of the anthropogenic carbon dioxide (CO2) released into the atmosphere in the past two centuries has been taken up by the ocean. As CO2 invades the surface ocean, carbonate ion concentrations and pH are lowered. Laboratory studies indicate that this reduces the calcification rates of marine calcifying organisms, including planktic foraminifera. Such a reduction in calcification ...

Structural buckling failure due to high external hydrostatic pressure is a major consideration in designing rings and long cylindrical shell-type structures. This paper presents a direct approach for enhancing buckling stability limits of thin-walled rings/long cylinders that are fabricated from multiangle fibrous laminated composite lay-ups. The mathematical formulation employs the classical l...

Single-walled carbon nanotubes (SWNTs) with various unique properties have attracted great attention in cancer theranostics. Herein, SWNTs are coated with a shell of polydopamine (PDA), which is further modified by polyethylene glycol (PEG). The PDA shell in the obtained SWNT@PDA-PEG could chelate Mn(2+), which together with metallic nanoparticulate impurities anchored on SWNTs offer enhanced b...

The coupling of a dynamically adaptive Eulerian Cartesian detonation solver with hierarchical time step refinement to a Lagrangian thin-shell finite element solver with fracture and fragmentation capabilities is presented. The approach uses a level set function to implicitly represent arbitrarily evolving solid structures on the Cartesian mesh. The auxiliary algorithm used to efficiently transf...

Thin-walled cylindrical shells are used in elements of highly loaded products mechanical engineering and energy. Along with their frequent use production, experimental research laboratories is also carried out constantly. This allows to simulate the behavior shell when exposed external forces. But sometimes conducting an experiment becomes little possible due limitation power apparatus modeling...
