The large number of cytofectin and co-lipid combinations currently used for lipoplex-mediated gene delivery reflects the fact that the optimal cytofectin/co-lipid combination varies with the application. The effects of structural changes in both cytofectin and co-lipid were systematically examined to identify structure-activity relationships. Specifically, alkyl chain length, degree of unsatura...

Through multi-component self-assembly of chiral phenylethylamine, 1-alkyl-2-imidazolecarboxaldehyde and iron(ii) ions, two couples of enantiomeric iron(ii) complexes , , and with the formula of fac-Λ or Δ-[Fe(L)3](2+)(L = R or S-1-phenyl-N-(1-alkyl-1H-imidazol-2-ylmethylene)ethanamine) have been designed and synthesized as building blocks. Further binary cocrystallization of the prefabricated e...

Glyceryl ethers are present in most mammalian tissues (17, 21) but have until recently been isolated from only a few anaerobic microorganisms (1, 4, 8, 9). Recently, Kamio et al. (12) have shown that these lipids are present in a number of anaerobic soil microorganisms, and Meyer and Meyer (14) have reported alk-1'-enyl glyceryl ethers (plasmalogens) in Treponema pallidum (Reiter) isolated from...

In this study we report the first organic hydrophilic dye employed for 100% water-based electrolyte DSSCs. We show that the replacement of alkyl by glycolic chains in the dye structure is able to provide excellent wettability, resulting in an efficient system with remarkably reduced desorption problems that allowed us to perform tests over a wide pH range. By changing the electrolyte compositio...

The ultrafast structural dynamics inside the bilayers of dilauroylphosphatidylcholine (DLPC) and dipalmitoylphosphatidylcholine vesicles with 70, 90, and 125 nm diameters were directly measured with 2D IR vibrational echo spectroscopy. The antisymmetric CO stretch of tungsten hexacarbonyl was used as a vibrational probe and provided information on spectral diffusion (structural dynamics) in the...

The solvent extraction of gallium from a concentrated Jajarm Bayer process liquor containing 164.90 g/l of Na2O, 86.70 g/l of Al2O3 and 106.02 ppm of gallium was investigated using 10 vol.% Kelex100, a 7-alkyl substituted-8 hydroxyquinoline as an extractant, 10 vol.% etanol as a modifier and kerosene as a diluent. At (Vo :Va = 1.0:1.0) ...

Poly(alkyl-terphenyl piperidinium) ionomers and membranes were used for H2–O2 anion exchange membrane fuel cells, achieved a high power density of 2.58 W cm−2, which is new record polyaromatic-based cells. Details the study are described by Young Moo Lee co-workers in their Research Article on page 7710.

Morphological Information Encryption In article number 2206912, Wu, Zhang, Chen, and co-workers apply short alkyl chains modified polyvinyl alcohol as a molecular switch to control the static deformation of shape memory hydrogel. Thus, hydrogel morphologies can be encoded with encrypted morphological information, furtherly delivering hierarchical continuous information assistance programmed nea...
