Orange and Sunlight: A Recipe for Blisters

Equilibrium Onions ?

– We demonstrate the possibility of a stable equilibrium multi-lamellar (“onion”) phase in pure lamellar systems (no excess solvent) due to a sufficiently negative Gaussian curvature modulus. The onion phase is stabilized by non-linear elastic moduli coupled to a polydisperse size distribution (Apollonian packing) to allow space-filling without appreciable elastic distortion. This model is comp...

Paradigm change in hydrogel sensor manufacturing: from recipe-driven to specification-driven process optimization

The volume production of industrial hydrogel sensors lacks a quality-assuring manufacturing technique for thin polymer films with reproducible properties. Overcoming this problem requires a paradigm change from the current recipe-driven manufacturing process to a specification-driven one. This requires techniques to measure quality-determining hydrogel film properties as well as tools and metho...

A recipe for transplantation.

I am greatly honoured to be invited to give the Scott-Heron Lecture for 1983 but feel very inadequate to follow the distinguished doctors who have preceded me. The interest in the kidney was first aroused by a young woman with bilateral staghorn calculi, while working as a house surgeon with the late Mr. Cecil Woodside. Mr. Woodside was a general surgeon who had a special interest in the kidney...

A recipe for making

A recipe is given for making materials with negative refraction in acoustics, i.e., materials in which the group velocity is directed opposite to the phase velocity. The recipe consists of injecting many small particles into a bounded domain, filled with a material whose refraction coefficient is known. The number of small particles to be injected per unit volume around any point x is calculate...
