Isotopic and isotonic chains of superheavy nuclei are analyzed to search for spherical double shell closures beyond Z=82 and N=126 within the new effective field theory model of Furnstahl, Serot, and Tang for the relativistic nuclear many-body problem. We take into account several indicators to identify the occurrence of possible shell closures, such as two-nucleon separation energies, two-nucl...

The surface plasmon modes of spherical and oblate spheroidal core-shell colloids composed of a 312 nm diameter silica core and a 20 nm thick Au shell are investigated. Large arrays of uniaxially aligned coreshell colloids with size aspect ratios ranging from 1.0 to 1.7 are fabricated using a novel ion irradiation technique. Angleand polarization-resolved extinction spectroscopy is performed on ...

Colloidal polymer particles are an important class of materials finding use in both everyday and basic research applications. Tailoring their composition, shape, and functionality is of key importance. In this article, we describe a new class of shape-tunable core-shell microparticles. They are composed of a cross-linked polystyrene (PS) core and a poly(methyl methacrylate) (PMMA) shell of vary...

We describe the preparation and characterisation of inorganic-organic hybrid block copolymer silver nanoparticles via the preparation of spherical multi-responsive polymeric micelles of poly(N-methyl-2-vinyl pyridinium iodide)-block-poly(ethylene oxide), P2MVP(38)-b-PEO(211) and poly(acrylic acid)-block-poly(isopropyl acrylamide), PAA(55)-b-PNIPAAm(88) in the presence of AgNO(3). Hence, the P2M...

In this study, we design a new kind of spherical robot named BYQ-X. This robot has two moving statuses. When the robot moving on flat terrain, the spherical shell is folding, robot moves in traditional way by the pendulum. When the robot climbing a slope the climbing links stretch out and the spherical shell is unfolding. In this status the spherical is driven by electromotor directly. So the o...

Metallic spherical dome shells have received much attention in recent years because they have proven to possess highly impressive optical properties. The expected distinctive changes occurring owing to quantum confinement of conduction electrons in these nanoparticles as their thickness is reduced, have not been properly investigated. Here we carry out a detailed analytical derivation of the qu...

The spectrum and wave functions of 44 Ti are studied in oblique-basis calculations using spherical and SU(3) shell-model states. Although the results for 44 Ti are not as good as those previously reported for 24 Mg, due primarily to the strong spin-orbit interaction that generates significant splitting of the single-particle energies that breaks the SU(3) symmetry, a more careful quantitative a...
