Spontaneous propagation of self-assembly in a continuous medium
1Department of Mechanical Engineering, University of Michigan, Ann Arbor, Michigan 48109, USA.
Summary
Self-assembly spontaneously propagates in continuous media, transmitting local order over distances. This process creates defect-free, long-range ordered superlattices through a domino-like activation mechanism.
Area of Science:
- Materials Science
- Physics
- Chemistry
Background:
- Self-assembly is crucial for creating ordered materials.
- Understanding long-range propagation of order is a key challenge.
Purpose of the Study:
- To elucidate the mechanism of spontaneous self-assembly propagation.
- To demonstrate the creation of defect-free, long-range ordered structures.
Main Methods:
- Investigated a continuous medium system.
- Analyzed the role of dipole interactions in precursor destabilization.
- Observed the replication of order information during propagation.
Main Results:
- Demonstrated spontaneous spatial extension of self-assembly.
- Showcased the inheritance and replication of local order information.
- Successfully produced extremely long-range ordered superlattices without defects.
Conclusions:
- A novel mechanism for propagating self-assembly and order has been identified.
- This mechanism enables the creation of large-scale, defect-free ordered materials.

02:21Spontaneity
A spontaneous process is one that occurs naturally under certain conditions. A nonspontaneous process, on the other hand, will not take place unless it is “driven” by the continual input of energy from an external source. Processes have a natural tendency to occur in one direction under a given set of conditions. Water will naturally flow downhill (spontaneous process), but uphill flow (nonspontaneous process) requires outside intervention such as the use of a pump. Iron exposed to the earth’s...
01:18Assembly of Cytoskeletal Filaments
Cytoskeletal filaments are polymeric forms of smaller protein subunits. However, individual cytoskeletal filaments may easily disassemble or associate with other similar filaments to form rigid structures. Microfilaments, made of actin monomers, rely on actin-binding proteins to form bundles and create networks of individual actin filaments. Microtubules rely on microtubule-associated proteins (MAPs) to form sturdy cylindrical structures. However, the proteins involved in forming complex...
01:23Propagation of Action Potentials
The propagation of an action potential refers to the process by which a nerve impulse, or "action potential," travels along a neuron.
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...

01:04Anionic Chain-Growth Polymerization: Mechanism
The mechanism for anionic chain-growth polymerization involves initiation, propagation, and termination steps. In the initiation step, a nucleophilic anion, such as butyl lithium, initiates the polymerization process by attacking the π bond of the vinylic monomer. As a result, a carbanion, stabilized by the electron‐withdrawing group, is generated. The resulting carbanion acts as a Michael donor in the propagation step and attacks the second vinylic monomer, which acts as a Michael acceptor.
01:31Mechanism of Lamellipodia Formation
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...
01:42Actin Polymerization
Actin polymerization occurs through the head-to-tail association of binding sites on monomeric actin or G-actin to form filamentous or F-actin. The polymerization can be divided into three phases ̶ nucleation, elongation, and steady-state phase.
The nucleation phase involves forming a stable nucleus consisting of three actin monomers to form a new actin filament. Actin-binding proteins such as formins and Arp2/3 complex help filament growth post-nucleation. The Formins form straight actin...
