Based on tiles and on the Coven-Meyerowitz property, we present some examples and some general constructions of spectral subsets of integers.

Polymeric microparticles were produced following a three-step procedure involving (i) the production of an aqueous nanoemulsion of tri and monofunctional acrylate-based monomers droplets by an elongational-flow microemulsifier, (ii) the production of

A side-by-side capillaries microfluidic device was developed to fabricate drug loaded poly(acrylamide)/poly(methyl acrylate) Janus particles in the range of 59–240 μm by UV-assisted free radical polymerization. This system was characterized in ter

This paper presents a new route to the synthesis of uniform and size-controlled inorganic/organic composite microparticles by means of microreaction technology. Au-nanoparticles in the range of 3 to 14 nm are synthesized by reduction of tetrachloroau

Capillary-based flow-focusing and co-flow microsystems were developed to produce sphere-like polymer microparticles of adjustable sizes in the range of 50 to 600 μm with a narrow size distribution (CV < 5%) and different morphologies (core-shell, ja

The principle of micro continuous-flow synthesis of polymer microparticles using a co-flow arrangement with integrated in situ photopolymerization was applied for the synthesis of nanoporous acrylate particles and for polymer composite microparticles

In this study, we report on a novel method for the synthesis of poly(acrylamide) Trojan microparticles containing ketoprofen loaded poly(ethyl acrylate) or poly(methyl acrylate) nanoparticles. To develop these composite particles, a polymerizable nan

In free standing films of one smectic C* material, Chisso 1015, we observe circular islands, of greater thickness than the background film. These islands, nucleated by smoke particles, grow to an equilibrium diameter that is a function of their thick

The textures associated with a point defect centered in a circular domain of a thin film with XY-like ordering have been analyzed. The family of equilibrium textures, both stable and metastable, can be classified by a new radial topological number in

We observe textures on polar smectic films, using a new approach to achieve the polar geometry. We concentrate on 2D confined circular domains, for which we observed a “boojum” pattern and a previously unobserved spiral texture that reverses it d
