Figure 1: a) Stationary diffraction pattern of cBN powder, integrated over the Debye-Scherrer rings, measured with femtosecond x-ray pulses as a function of the diffraction angle 2θ. b ...

Choosing the right materials is key in paper marbling. You will require acrylic paints, carrageenan (a seaweed-derived thickener for the water), alum (a mordant that assists the paint in sticking to ...

Diffusion normally smoothes out concentration gradients, but Turing showed that differential diffusion can drive the formation of stationary patterns of activator and inhibitor (Fig. 1a ...
