A single-input state-switching building block harnessing internal instabilities

Bistable mechanisms are prevalent across a broad spectrum of applications due to their ability to maintain two distinct stable states. Their energy consumption is predominantly confined to the process of state transitions, thereby enhancing their efficiency. However, the transition often requires two distinct digital inputs, implicating the...

Pressure drop non-linearities in material extrusion additive manufacturing: A novel approach for pressure monitoring and numerical modeling

Fused Filament Fabrication is an additive manufacturing technique in which molten thermoplastic polymers are extruded through a nozzle. Therefore, the interplay between the viscoelastic nature of the polymer melt, temperature, printing conditions and nozzle shape may lead to inconsistent extrusion. To improve the extrusion control and...

Elastic Instabilities in Polymer-Solution Flow Through Porous Media

Crude oil has been an important source of energy for several decades now. Upon discovery of a crude oil reservoir until its abandonment, typically the oil recovery process can be classified in three stages. The primary and the secondary stage involve utilizing and maintaining reservoir pressure to recover oil respectively. The tertiary, or the...
