The Physics Teacher, 2006
In this note, we introduce a simple homemade toy called the brush-creeper, which can glide forward with no propellers, limbs, wheels, and seemingly no movement of any kind that can push forward against the ground. The toy arouses pupils' interest and their incentive to ask “Why?” in lessons related to friction.

ACM SIGGRAPH Computer Graphics, 1986
Paint brushes are modeled as a collection of bristles which evolve over the course of the stroke, leaving a realistic image of a sumi brush stroke. The major representational units are (1) Brush: a compound object composed of bristles, (2) Stroke: a trajectory of position and pressure, (3) Dip: a description of the ...

Proceedings of the Workshop on Non-Photorealistic Animation and Rendering, 2014
Non-Photorealistic Rendering covers a wide range of visual effects, and much work has been dedicated to create digital representations of traditional media --- either through artist controls or programmatically. We explore a variation of this work, which aims to create digital media that takes the metaphors of traditional media but applies them in ways

This chapter is an examination of the genre of “true portraits,” purported products of divine intervention. Their creators, who were usually Indigenous, were alienated from their creations because they were considered mere conduits of the divine. Emily C. Floyd analyzes the case of the “true portrait” reproduced in Juan María de Guevara y Cantos’s 1644

Wherein we learn that when working with plant terpene synthases, sometimes it is not the isotopes that get scrambled.

Semiflexible polymer brushes and the brush-mushroom crossover
Soft Matter, 2015Semiflexible polymers end-grafted to a repulsive planar substrate under good solvent conditions are studied by scaling arguments, computer simulations, and self-consistent field theory. Varying the chain length N, persistence length lp, and grafting density σg, the chain linear dimensions and distribution functions of all monomers and of the free chain

Molecular Bottlebrushes Featuring Brush-on-Brush Architecture
ACS Macro Letters, 2019Molecular bottlebrushes featuring brush-on-brush (BoB) architecture were prepared by combining azide-alkyne click chemistry, ring-opening polymerization (ROP), and atom transfer radical polymerization (ATRP). Primary side chains of diblock copolymers with a poly(ε-caprolactone) (PCL) block and a poly(α-bromo-ε-caprolactone) (P(CL-Br)) block were ...

Science, 1991
Polymers attached by one end to an interface at relatively high coverage stretch away from the interface to avoid overlapping, forming a polymer "brush." This simple picture may serve as the basis for models in diverse interfacial systems in polymer science, such as polymeric surfactants, stabilized suspensions of colloidal particles, and structures ...
