Polyethylene glycol (PEG) reagents offer numerous favorable characteristics, including high water solubility, high mobility in solution, lack of toxicity and immunogenicity, and ready clearance from the body.
Mesoporous materials are formed by a self-assembly process from combined solutions of sol-gel precursors (e.g., metal alkoxides) and structure-directing amphiphiles, usually block-copolymers or surfactants.
Fluorocarbon polymers, like small-molecule fluorocarbons, exhibit increased thermal stability, hydrophobicity, lipophobicity, improved chemical resistance, and decreased intermolecular attractive forces in comparison to their hydrocarbon analogs.
The supply of low cost, high purity and effective Reversible addition−fragmentation chain-transfer (RAFT) Agents is the essential element in the industrial implementation of RAFT polymerization technology.
The field of organic electronics has emerged as the next-generation technology potentially enabling ultra-thin, large-area, and/or flexible devices, consisting of organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs), and organic photovoltaics (OPVs).
A series of polymerization were carried out using RAFT agents and monomers yielding well-defined polymers with narrow molecular weight distributions. The process allows radical-initiated growing polymer chains to degeneratively transfer reactivity from one to another through the use of key
In this article, we discuss issues critical to successful application of the electrospinning technique, including control of individual nanofibers to form secondary structures and assembly of nanofibers into 3D architectures.
Atomic layer deposition (ALD) techniques have emerged in the last ten years to meet various needs including semiconductor device miniaturization, conformal deposition on porous structures and coating of nanoparticles. ALD is based on two sequential self-limiting surface reactions.
The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear
Innovation in dental restorative materials is driven by the need for biocompatible and natural-appearing restoration alternatives. Conventional dental materials like amalgam and composite resins have inherent disadvantages.
Nanoclays are nanoparticles of layered mineral silicates. Montmorillonite, bentonite, and halloysite nanoclays and organoclays are used in polymer-clay nanocomposites, as rheology modifiers, and drug delivery carriers.
One of the desirable end-goals of materials science research is the development of multi-functional materials. These materials are defined as compositions that bring more than one property enhancement to a particular application, thus allowing the material to replace more than
Atom transfer radical polymerization (ATRP) has emerged as one of the most successful synthetic techniques for the preparation of polymers with predetermined molecular weights, narrow molecular weight distributions, and high degrees of chain end functionalities.
MALDI-TOF MS is a tool for confirming end group identity & transformations, verifying successful & complete conjugation. Functionalized polymers enable a quick & efficient route for synthesis of various polymer conjugates for many applications if apt end group is present.
