1.1.1.1 What is a Polymer Network? Polymer networks are molecular-based systems, whose network structure depends upon covalent or non-covalent interactions between macromolecules. The interactions can be simple covalent cross-links, or more complex junction zone or particulate-type interactions. Figure ...
Polymer–drug conjugates have long been a mainstay of the drug delivery field, with several conjugates successfully translated into clinical practice. The conjugation of therapeutic agents to polymeric carriers, such as polyethylene glycol, offers several advantages, including improved drug solubilization, ...
This behavior is critical for effective surgical training, especially when using high-energy intervention devices like electrocautery or radiofrequency ablation tools. Our Solution: The "e-tissue" Hydrogel Drawing inspiration from the Maillard reaction, the chemical process responsible for food browning, ...
The possibility of controlling the multiple degrees of freedom of light, including the amplitude-phase distribution and polarization state, has gained traction of late, for what is now referred to as structured light1. This in turn has opened up the way for many unique techniques and devices exp...
What is a polymer composed of nucleotide monomers responsible for the reproduction of genetic material and proteins called?Nucleotides:A monomer is a molecule that serves as the building block of larger molecules called polymers. One example of monomer...

What Is a Polymer? Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded. Some polymers bend and stretch, like rubber and polyester. Others are hard and tough, like ...
But what exactly is meant by the term ‘energy density’? It is known since 1920 that the plasma chemical decomposition of gases is determined by the energy invested per particle within the active plasma zone, depending on the power input per plasma volume multiplied by the residence time, ...
Is this particular situation detectable in simulations and what is its significance? In a real world, the encapsulating cavity may not be spherical. Researchers may enclose a biopolymer in a quasi-two-dimensional cage and release it later though a pore or a canal for applications. It addresses ...
