Future Fighting Using Swarms

Primitive military history shows the primary conflict tactic was unfocused and chaotic melee where each individual fighter operated on their own and engaged other individuals adjacent to them, and when that one on one engagement was completed, sought out another adjacent enemy to engage. Little or no command and control functions existed. There was often […]

Colloidal Camouflage

Cuttlefish dynamically change both the color and texture of their skin to create camouflage that matches the environment around them. A University of Nebraska research team is doing the same thing using colloids in a multilayered structure. When light hits the colloid layer, heat convection reassembles it to replicate the light pattern. This technique is […]

Smart Colloids

Smart fluids have particles added to them that allow characteristics of the fluid to be controlled by an external factor such as an electro-magnetic field or light or sound. A common example is using magnetic particles in fluid to alter the viscosity and create a controllable damping effect or reduction in vibration. Think shock absorber […]

Photonic Colloidal Crystals

A colloid is a suspension or dispersion of one substance inside another, typically held in place by electromagnetic fields. Examples of common colloids include, blood, milk, ink, gelatin, smoke and fog particles. Destabilizing the electromagnetic field often causes the particles to precipitate out of their suspended state. Colloidal particles can also self-assemble or crystallize into […]

Glass Grows Up

From using colloids to model the behavior of glasses, to windows that can change their tint, to adding peptides that can repel dirt, our understanding of the characteristics of glass is changing. How long can it be before we actually have transparent aluminum? Materials scientists find better model for glass creation – [nanowerk.com] Glasses form […]
