Superposition State Molecular Dynamics
The ergodic sampling of rough energy landscapes is crucial for understanding phenomena like protein folding, peptide aggregation, polymer dynamics, and the glass transition. These rough energy landscapes are characterized by the presence of many local minima separated by high energy barriers, where Molecular Dynamics MD fails to satisfy ergodicity. To...
Ternary Complexes Comprising Polyphosphoramidate Gene Carriers With Different Types of Charge Groups Improve Transfection Efficiency
To understand the influence of charge groups on transfection mediated by polymer complexes, we have synthesized a series of biodegradable and cationic polyphosphoramidates PPAs with an identical backbone but different side chains. The mechanism of enhancement in transfection efficiency by the mixture carriers appears to be unrelated to the particle...
Thermodynamic Measurements and Predictions of the Adsorption of Short-Chain Peptides on Nanothin Polymer Films
This contribution describes experimental measurements of sub molecular-level interaction energies involved in the process of peptide adsorption on polymer films. The objective of this study was to use surface plasmon resonance SPR spectroscopy to measure the Gibbs energy change on adsorption Gad for pairs of various homopeptides on highly uniform,...
Polymer-Dispersed Bicontinuous Cubic Glycolipid Nanoparticles
The paper reveals that certain amphiphilic polymers such as PEO-PPO-PEO triblock copolymer PL can directly disperse a cubic glycolipid, 1-O-phytanyl--D-xyloside (-XP), into bicontinuous cubic nanoparticles in water medium. The use of synchrotron small-angle X-ray diffraction SSAXD permitted the identification of the exact structure of these dispersed particles in the colloidal...
Poly(ethylene oxide sulfide): New Poly(ethylene glycol) Derivatives Degradable in Reductive Conditions
Poly ethylene oxide sulfide PEOS, polymers consisting of an internal ethylene oxide oligomer and disulfide linkage, were synthesized and characterized. The degree of polymerization was dependent upon temperature, dimethyl sulfoxide condition, and monomer hydrophobicity. The stability of PEOS was measured by the size exclusion chromatography method after the incubation both...
Liquid-Liquid Equilibrium Data, Viscosities, and Densities of Aqueous Mixtures of Poly(propylene glycol) With Tri-sodium Citrate at 298.15 K
Aqueous two-phase systems, which are useful for the separation of biological products from the complex mixtures in which they are produced,1,2 can be made from aqueous solutions of two water-soluble polymers or a polymer and a salt. Poly ethylene glycol PEG is often used in this technique, and there are...
Mechanism of Optically Inscribed High-Efficiency Diffraction Gratings in Azo Polymer Films
According to this paper, both volume refractive index and surface profile diffraction gratings could be laser inscribed in azo polymer thin films. The mechanism for the high-efficiency photoinduced surface gratings appears to be isomerization driven mass transport, with grating depths of up to 1 m achievable with films of an...
In Situ Immobilization of Proteins and RGD Peptide on Polyurethane Surfaces via Poly(ethylene oxide) Coupling Polymers for Human Endothelial Cell Growth
This white paper reveals about the pre-SMA synthesis and PEU surface modification that were characterized using nuclear magnetic resonance spectroscopy (1H NMR), attenuated total reflection infrared spectroscopy (ATR-FTIR), and X-ray photoelectron spectroscopy XPS. The cell morphologies were investigated by optical inverted microscopy OIM and scanning electrical microscopy SEM. The gelatin-...
New Polymer Synthesis by Nitroxide Mediated Living Radical Polymerizations
This white paper considers radical polymerization which may be considered a mature technology with millions of tons of vinyl based homo- and copolymers being produced annually. This perception of maturity is based on the fact that free radical polymerization is so widely used industrially and in research laboratories for the...

Diluted Seawater Boosts Nutritional Content of Tomatoes
You can grow a healthier tomato by watering it with diluted seawater, a new study shows. In an experiment in which researchers grew cherry tomatoes in either freshwater or a diluted solution of 12 percent seawater, the salt-water tomatoes developed higher levels of vitamin C, vitamin E, dihydrolipoic acid and...
Chinese Ants Show Promise in Fighting Arthritis, Other Diseases
Substances found in a type of Chinese ant may provide anti-inflammatory and painkilling benefits against several diseases, a new report says. Chemists analyzing extracts from a Chinese medicinal ant, Polyrhacis lamellidens , found two polyketides, potent natural products that other studies have deemed as promising treatments for arthritis, bacterial...
