Bioconjugate Chemistry 2009: Polyaspartamide-Based Oligo-ethylenimine Brushes with High Buffer Capacity and Low Cytotoxicity for Highly Efficient Gene Delivery
Polyaspartamide-based oligo-ethylenimine brushes (PASP-EDA, PASP-TEPA, PASP-PEHA, and PASP-PEI 423) were synthesized from polysuccinimide (PSI) via a ring-opening reaction with N-Boc protected ethylenediamine, tetraethylenepentamine, pentaethylenehexamine, and linear polyethylenimine (Mn 423), respectively. PASP-TEPA, PASP-PEHA, and PASP-PEI 423 possess high buffer capacity between pH 5 and pH 7, ...

Ultrasonic irradiation enhanced cell nucleation: An effective approach to microcellular foams of both high cell density and expansion ratio
In this work, ultrasonic irradiation (UI) was used as the external energy source to assist polystyrene foaming process by using supercritical CO2 as the physical blowing agent. It is shown that by introducing the UI at the very start of foaming, the resultant polymer foam exhibited significant and concurrent increase in cell density, i.e., three orders of magnitude, and expansion ratio, i.e., 1&nd...

Synthesis of Novel High-Performance Polymers via Pd-Catalyzed Amination of Dibromoarenes with Primary Aromatic Diamines.
A series of novel polymers have been obtained by the condensation polymerization of different dibromoarenes with different primary aromatic diamines via palladium-catalyzed aryl amination reaction. The structures of polymers are characterized by means of FT-IR, H NMR spectroscopy, and elemental analysis; the results show an agreement with the proposed structure. DSC and TG measurements show that...

Interfacial entanglement between glassy polymers investigated by nanofractography with high-resolution scanning electron microscopy.
Fracture surfaces created during the interfacial failure of weak interfaces between glassy polymers were investigated with high-resolution scanning electron microscopy (HR-SEM). As reported in an earlier communication (Macromol. Rapid Commun. 2007, 28, 915-921), we found that interfacial failures between immiscible polymers produced large number of nanosized fibrils on the fracture surfaces. In or...

High strength disclinations in liquid crystalline polymers with X-shaped two-dimensional mesogenic units
Textures of liquid crystalline polymers with two-dimensional mesogens have been investigated by using polarizing optical microscopy.Disclinations, strength lSl up to 3/2 and 5/2, were found easily in each sample. Occasionally, even high strength disclination pair can befound. These high strength disclinations are very sable in high temperature although they are energy unfavorable according to the ...

Preparation of acrylate polymer/silica nanocomposite particles with high silica encapsulation efficiency via miniemulsion polymerization
Acrylate polymer/silica nanocomposite particles were prepared through miniemulsion polymerization by using of methyl methacrylate/butyl acrylate mixture containing the well-dispersed nanometer-sized silica particles coupled with 3-(trimethoxysilyl)propyl methacrylate (MPS). The encapsulation efficiency of silica particles were determined through the elution and hydrofluoride acid etching experimen...
