Amphiphilic properties

Ebook "Studies on “perfect” hyperbranched chains free in solution and confined in a cylindrical pore" also reveals how the chain structure of amphiphilic hyperbranched block and graft copolymers affect their solution properties, including the establishments of several classic scaling laws that relate the chain size and the intrinsic viscosity to the overall molar mass and the subchain length, respectively. This work has led to numerous publications in high-impact peer-reviewed journals.

With amphiphilic properties, cellulose molecules are expected to adsorb at the O/W interface and be capable of stabilizing emulsions. The effect of solvent quality on the formation and stability of cellulose-based O/W emulsions was evaluated in different alkaline systems: NaOH, NaOH-urea and tetrabutylammonium hydroxide (TBAH).

The unique photophysical properties of the Ln(III) series has led to significant research efforts being directed towards their application in sensors. However, for “real-life” applications, these sensors should ideally be immobilised onto surfaces without loss of function.

Acetylcholinesterase subunits of type T (AChET) possess an alternatively spliced C-terminal peptide (t peptide) which endows them with amphiphilic properties, the capacity to form various homo-oligomers and to associate, as a tetra-mer, with anchoring proteins containing a proline rich attachment domain (PRAD). The t peptide contains seven conserved aromatic residues.

Polyurethanes are block copolymers composed of alternating short hard segments and long flexible soft segments that are thermodynamically incompatible at the temperature of use [1,2]. Phase separation of segmented polyurethanes (SPU) with a limited hard segment content results in hard segment rich domains dispersed in a continuous matrix of the soft segments [3]. The hard domains act as physical crosslink providing the polymer with mechanical strength while the soft matrix contributes to the elastomeric properties [4,5]....

Nanotechnology has received tremendous interest over the last decade, not only from the scientific community but also from a business perspective and from the general public. Although nanotechnology is still at the largely unexplored frontier of science, it has the potential for extremely exciting technological innovations that will have an enormous impact on areas as diverse as information technology, medicine, energy supply and probably many others. The miniaturization of devices and structures will impact the speed of devices and information storage capacity.
