Experiments, simulations, and theoretical treatments of granular materials typically feature circular or elliptical grains. However, grains found in natural systems often have flat faces that introduce local rotational constraints; these constraints been shown to affect, for example, the jamming transition, discontinuous shear thickening, ordered states colloids thermalized In this work, we exp...

Hertzian contact of a rigid sphere and highly deformable soft solid is investigated using integrated photoelasticity. The experiments are performed by pressing styrene 15 mm diameter against 44 × 47 mm3 cuboid made 5% wt. gelatin, inside circular polariscope, with range forces. emerging light rays processed considering that the retardation each ray carries cumulative effect traversing contact-i...

Abstract Polarized spectroscopic photodetection enables numerous applications in diverse areas such as sensing, industrial quality control, and visible light communications. Although organic photodetectors (OPDs) can offer a cost‐effective alternative to silicon‐based technology—particularly when flexibility large‐area arrays are desired—polarized OPDs only beginning receive due research intere...
