Gas-solid fluidization technology has been commercialized in many industrial applications
since its implementation in the fluid catalytic cracking process in the early 1940s, however …

Concrete is flying off, but it is simultaneously facing tremendous challenges in terms of
environmental impact, financial needs, societal acceptance and image. Based on an …

Suspensions are composed of mixtures of particles and fluid and are omnipresent in natural
phenomena and in industrial processes. The present paper addresses the rheology of …

A comprehensive review is presented of the physical behavior of yield stress materials in
soft condensed matter, which encompasses a broad range of materials from colloidal …

When deformed beyond their elastic limits, crystalline solids flow plastically via particle
rearrangements localized around structural defects. Disordered solids also flow, but without …

A consensus is emerging that discontinuous shear thickening (DST) in dense suspensions
marks a transition from a flow state where particles remain well separated by lubrication …

The relationship between critical state and particle shape corresponds to the most
fundamental aspect of the mechanics of granular materials. This paper presents an …

In simple fluids, such as water, invariance under parity and time-reversal symmetry imposes
that the rotation of constituent 'atoms' is determined by the flow and that viscous stresses …

Additive manufacturing (AM) or 3D printing is beginning to mature from a rapid prototyping to
an industrial production technology. However, there are still a lot of fundamental questions …

Discovery of fundamental principles which govern and limit effective locomotion (self-
propulsion) is of intellectual interest and practical importance. Human technology has …
