Here, we describe protocols for the preparation of trans-cyclobutane fused cyclooctenes (tCBCO), their polymerization to prepare depolymerizable olefinic polymers, and the depolymerization of these polymers under mild conditions. Additionally, protocols for the preparation of depolymerizable networks and compression molding of rigid linear plastics based on this system are described.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Polymeric materials are widely used in civil structures, with uses ranging from very soft sealants to more rigid pipes in water and wastewater systems. The most basic definition of a polymer is a molecular structure with repeating subunits. The term polymer comes from Greek, where "poly" means many, and "-mer" means basic unit. Monomers, or single mers, are the specific repeating units. With...

The present work describes a method to fabricate micellar nanocrystals, an emerging major class of nanobiomaterials. This method combines top-down electrospray, bottom-up self-assembly, and solvent-based structure control. The fabrication method is largely continuous, can produce high quality products, and possesses an inexpensive means of structure control.

A Testing Platform for Durability Studies of Polymers and Fiber-reinforced Polymer Composites under Concurrent Hygrothermo-mechanical Stimuli
0 Views •
2014
The durability of polymers and fiber-reinforced polymer composites in service is a critical aspect for their designs and condition-based maintenance. We present a novel low-cost laboratory testing platform for the investigation of the influence of concurrent mechanical and environmental loadings, and may help design more efficient yet safer composite structures.
FAQs
Block composition determines the balance between water-repelling and water-compatible segments, while chain length affects how those segments pack within the assembled structure. Together, these variables influence micelle size and stability. Adjusting them allows bioengineers to tune the architecture for different cargo types or delivery requirements rather than relying on a single fixed design.
Micellar assembly becomes favored above a suitable concentration or when solvent conditions promote association of the water-repelling segments. Clustering those segments reduces unfavorable interactions with the surrounding solvent, while the compatible segments remain exposed. Consequently, changing concentration or solvent conditions can determine whether assembly occurs and can affect the resulting structure’s stability.
The inner region provides a water-repelling environment that can accommodate poorly water-soluble compounds, while the exposed water-compatible segments form the outer surface. This core and surface arrangement can also shield cargo from its surroundings. Those features make micellar polymer structure useful when a bioengineering design must combine solubilization with controlled delivery.
A design begins with the amphiphilic polymer’s block composition and chain length, followed by selection of concentration and solvent conditions that favor self-assembly. The resulting micelle size and stability are important outcomes because they reflect how successfully the components organize. These considerations help align the structure with the intended cargo and biomedical use.
Polymeric micelles are useful when a compound has limited compatibility with water and therefore requires a more favorable internal environment for incorporation. Their water-repelling core can help solubilize such cargo, while the outer region remains compatible with the surrounding solvent. In bioengineering, this architecture supports carrier designs intended for controlled delivery.
Its tunable architecture provides a framework for designing carriers for drugs, imaging agents, and other biomedical materials. By changing polymer organization and assembly conditions, researchers can influence properties such as size and stability while preserving the core and surface arrangement needed for cargo handling. This connects nanoscale structure with practical carrier performance.
