Applied SciencesParticle shape is a critical factor governing the macroscopic behavior of granular materials. While the Discrete Element Method (DEM) has proven to be a powerful tool for modeling these materials, the accurate representation of particles with realistic ...

Force-Guiding Particle Chains for Shape-Shifting Displays
, 2014 We present design and implementation of a chain of particles that can be programmed to fold the chain into a given curve. The particles guide an external force to fold, therefore the particles are simple and amenable for miniaturization.

Poroelastic shape relaxation of hydrogel particles
Soft Matter, 2021 We describe a straightforward way to determine the poroelastic diffusion coefficient of a hydrogel particle by first indenting itviaswelling in a granular packing, and then monitoring how its indented shape relaxes after it is removed.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Nature, 1938 THE minerals found in clays and soil colloids are usually considered to be plate-shaped and to have layer lattices built up from sheets of silicon – oxygen tetrahedra. This may be true in the majority of cases, but rod- or needle-shaped particles can also occur and should not be overlooked. Their presence may be due to one of the following two reasons.

Shapes of laser-produced CsH particles [PDF]
Physical Review Letters, 1989 Shapes of laser-produced alkali-hydride crystalline particles (laser snow) are observed for the first time. Particles are suspended by an electric field so as to grow large enough to be observed by an optical microscope. It is found that the particles are single crystals and have particular shapes depending on the gas temperature and the laser-light ...

FEBS Letters, EarlyView.Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
