Bubble Shape Oscillations and the Onset of Sonoluminescence [PDF]

, 1995
An air bubble trapped in water by an oscillating acoustic field undergoes either radial or nonspherical pulsations depending on the strength of the forcing pressure.

Are Nanoparticles Spherical or Quasi‐Spherical? [PDF]

Chemistry – A European Journal, 2015
AbstractThe geometry of quasi‐spherical nanoparticles is investigated. The combination of SEM imaging and electrochemical nano‐impact experiments is demonstrated to allow sizing and characterization of the geometry of single silver nanoparticles.

Preparation of 304 Stainless Steel Powder for 3D Printing by Vacuum-Induced Multistage Atomization

Frontiers in Materials, 2021
A vacuum-induced multistage atomization process was adopted to fabricate the high-performance 304 stainless steel powder for 3D printing, based on the flexible control of the droplet spheroidization and solidification process. The 36.7 μm-median diameter

Spherical Categories

Advances in Mathematics, 1999
This paper is a study of monoidal categories with duals where the tensor product need not be commutative. The motivating examples are categories of representations of Hopf algebras and the motivating application is the definition of 6j-symbols as used in topological field theories. We introduce the new notion of a spherical category.

Effects of atmospheric sphericity on stratospheric chemistry and dynamics over Antarctica [PDF]

, 2005
Atmospheric sphericity is an important factor that must be considered in order to evaluate an accurate ozone loss rate in the polar stratosphere. The built-in plane-parallel radiative transfer scheme of a nudging chemical transport model (CTM) and an ...

Skeletal Rearrangements of the C₂₄₀ Fullerene: Efficient Topological Descriptors for Monitoring Stone–Wales Transformations

Mathematics, 2020
Stone–Wales rearrangements of the fullerene surface are an uncharted field in theoretical chemistry. Here, we study them on the example of the giant icosahedral fullerene C240 to demonstrate the complex chemical mechanisms emerging on its carbon skeleton.

The stress transmission universality classes of periodic granular arrays [PDF]

, 2001
The transmission of stress is analysed for static periodic arrays of rigid grains, with perfect and zero friction. For minimal coordination number (which is sensitive to friction, sphericity and dimensionality), the stress distribution is soluble without
