We introduce a model detector which registers the passage of a particle through the detector location, without substantially perturbing the particle wave function. (The exact time of passage is not determined in such measurements.) We then show that our detector can operate in a classically forbidden region and register particles passing through a certain point under a potential barrier. We sho...

Abstract We consider the problem of determining, within an elastic isotropic nanoplate in bending, possible presence inclusion made different material. Under suitable a priori assumptions on unknown inclusion, we provide quantitative upper and lower estimates for area defect terms works exerted by boundary data when is present it absent.

Bi₂Se₃ nanocrystals with various morphologies, including nanotower, nanoplate, nanoflake, nanobeam and nanowire, have been synthesized. Well-distinguished Shubnikov-de Haas (SdH) oscillations were observed in Bi₂Se₃ nanoplates and nanobeams. Careful analysis of the SdH oscillations suggests the existence of Berry's phase π, which confirms the quantum transport of the surface Dirac fermions in b...

In this paper, we successfully grow GaAs/GaSb core-shell heterostructure nanowires (NWs) by molecular beam epitaxy (MBE). The as-grown GaSb shell layer forms a wurtzite structure instead of the zinc blende structure that has been commonly reported. Meanwhile, a bulgy GaSb nanoplate also appears on top of GaAs/GaSb core-shell NWs and possesses a pure zinc blende phase. The growth mode for core-s...

Correction for ‘Spherical Co 3 S 4 grown directly on Ni–Fe sulfides as a porous nanoplate array FeNi foam: highly efficient and durable bifunctional catalyst overall water splitting’ by Jun Shen et al. , J. Mater. Chem. A 2022, 10 5442–5451, DOI: 10.1039/d1ta07504g.

Subject to the assumption that sub-barrier fusion is described by an effective one-dimensional energy-independent local potential barrier, the Jeffreys-Wentzel-Kramers-Brillouin approximation for the fusion cross sections is inverted to determine this effective potential. Potential barriers, with their associated experimental errors, are presented for 13C+ 13C and 40Ca+ 40Ca, and the assumption...

In this study, silicon carbide (SiC) nanoplates are prepared from the waste quart tube (main composition: dioxide) and autoclave lining polytetrafluoroethylene) produced in laboratory. The reaction is carried a stainless steel at 600 °C through magnesium reduction route. Electron microscopy investigations show that nanoplate thickness of SiC sample about 20 nm, edge length 200 nm. Furthermore, ...

In this article, classical plate theory (CPT) is reformulated using the nonlocal differential constitutive relations of Eringen to develop an equivalent continuum model for orthotropic triangular nanoplates. The equations of motion are derived and the Galerkin’s approach in conjunction with the area coordinates is used as a basis for the solution. Nonlocal theories are employed to bring out the...
