Light-Stabilized Dynamic Materials

A dynamic lattice model for heterogeneous materials

In this paper, the mechanical behavior of three-phase inhomogeneous materials is modeled using the meso-scale model with lattice beams for static and dynamic analyses. The Timoshenko beam theory is applied instead of the classical Euler-Bernoulli beam theory and the mechanical properties of lattice beam connection are derived based on the continuum medium using the non-local continuum theory. T...

Biotemplated Palladium Catalysts Can Be Stabilized on Different Support Materials

Catalytic materials used in many industrial and energy-conversion processes must be durable to maximize their useful lifetimes, especially when expensive precious metal catalysts are utilized. Conventional methods of catalyst formation typically use synthetic stabilizers and reductants to form nanostructures with high surface area and catalytic activity. Synthesized nanomaterials are then mixed...

Particle?Stabilized Materials: Dry Oils and (Polymerized) Non?Aqueous Foams

Oil (liquids with low surface tension and practically immiscible with water) drops can be dispersed in air if relatively oleophobic particles are available. However, such particles with oil-repellent surfaces cannot simply be prepared by controlling the particle surface chemistry alone. Herein the preparation of oil-in-air materials (oil marbles, dry oils) by changing the wetting behavior of pa...

Spiropyran-based dynamic materials.

In the past few years, spiropyran has emerged as the molecule-of-choice for the construction of novel dynamic materials. This unique molecular switch undergoes structural isomerisation in response to a variety of orthogonal stimuli, e.g. light, temperature, metal ions, redox potential, and mechanical stress. Incorporation of this switch onto macromolecular supports or inorganic scaffolds allows...
