Random solids and random solidification: What can be learned by exploring systems obeying permanent random constraints?

, 1999
In many interesting physical settings, such as the vulcanization of rubber, the introduction of permanent random constraints between the constituents of a homogeneous fluid can cause a phase transition to a random solid state. In this random solid state,

Supergiant Barocaloric Effects in Acetoxy Silicone Rubber over a Wide Temperature Range: Great Potential for Solid-state Cooling [PDF]

, 2020
Solid-state cooling based on caloric effects is considered a viable alternative to replace the conventional vapor-compression refrigeration systems. Regarding barocaloric materials, recent results show that elastomers are promising candidates for cooling

The Effect of Ingredients Mixing Sequence in Rubber Compounding upon Vulcanization Kinetics of Natural Rubber: An Autocatalytic Model Study

Indonesian Journal of Chemistry, 2018
This study examined the effect of ingredients mixing sequence to the vulcanization kinetics of natural rubber. The effects of mixing temperature, vulcanization temperature, and the carbon black type upon the kinetics were also studied by using rheography

Elasticity near the vulcanization transition

, 1998
Signatures of the vulcanization transition--amorphous solidification induced by the random crosslinking of macromolecules--include the random localization of a fraction of the particles and the emergence of a nonzero static shear modulus.

Programmable Continuous Electrowetting of Liquid Metal for Reconfigurable Electronics

Advanced Materials, EarlyView.
This work introduces a programmable continuous electrowetting (CEW) approach for the dynamic manipulation of liquid metal (LM), enabling directional control via electrochemical modulation. By leveraging laser‐induced graphene (LIG) substrates, a wide range of utilities is demonstrated, including fluidic “valves,” logic gates, and reconfigurable ...

Closed‐Loop and Sustainable 4D Printing of Multi‐Stimuli‐Responsive Sulfur‐Rich Polymer Composites for Autonomous Task Execution

Advanced Materials, EarlyView.
Closed‐loop and sustainable 4D printing of sulfur‐rich polymer composites is demonstrated for the first time using loosely crosslinked poly(phenylene polysulfide) networks (PSNs) and their magnetic composites (MPSNs). 3D‐printed PSNs and MPSNs exhibit shape‐morphing capabilities and can be directly reprinted into new form factors and magneto‐responsive
