Abstract We report the swelling ratio and network structure of a poly(vinyl alcohol) (PVA) gel chemically crosslinked by glutaraldehyde with different degrees of crosslinks. Microcrystallites were formed in a chemical PVA gel during a drying process and were confirmed by X‐Ray diffraction (XRD) measurements and Fourie…

The conversion of biogas to electricity presents an attractive niche application for fuel cells. Thus attempts have been made to use biogas as a fuel for high temperature fuel cell systems such as SOFC. Biogas can be converted to hydrogen-rich fuel in a reforming process. For hydrocarbon-based fuel, three types of fue…

A carbonyl reductase from Sporobolomyces salmonicolor reduced para-substituted acetophenones with low enantioselectivity. Enzyme-substrate docking studies revealed that residues M242 and Q245 were in close proximity to the para-substituent of acetophenones in the substrate binding site. Site-saturation mutagenesis of…

There is a need for continuing development of CO 2 -soluble polymers to be used as suitable surfactants, ligands, or phase transfer agents in CO 2 solvent processes. Identifying CO 2 /polymer solubility trends will help to enhance the search for CO 2 -soluble polymers. The synthesis and characterization of structurall…

Substitutional doping properties of silicon dioxide are investigated systematically with ab initio calculations. The dopants include a range of elements from group-III, group-V, and group-VII. We find that ${\text{SiO}}_{2}$ has a relatively symmetric doping profile in terms of its ionization energies, i.e., relativel…

For an investigation of thermodynamic synthesis feasibility of pure silica zeolites, we applied computer simulations with two force fields BS and SLC. The recently developed BS force field excellently fits experimental enthalpies of pure silica zeolites with respect to quartz. On the basis of calculations with the BS…

In this paper, we first present the study of the formation of phenyltrichlorosilane film and self-assembled monolayers of phenylalkyltrichlorosilane (PATCl), pentafluoro-phenylalkyltrichlorosilane (PFATCl), and a mixture of the two, on silicon covered by its native oxide. These monolayers are shown to grow in two step…

Analytic expressions for contributions to the inelastic electron tunneling spectrum (IETS) from surface magnon scattering and magnetic impurity scattering are obtained. It is shown that surface magnon scattering alone does not lead to peaks in the IETS. The peaks at small bias often observed in the IETS of magnetic ju…

The colorless naphthalene tetracarboxylic bisimides were laterally extended with imidazole rings to give colored and highly fluorescent materials. Donor-substituted phenyl groups at the imidazole rings cause further bathochromic shifts in fluorescence where the strong solvent influence in the spectra is typical for a…

Theoretical approaches based on the indices of local curvature and polarizability have been used for estimation of reactivity of C60 derivatives – C60O and C60F18 – in the model reaction of O addition. The first of this species as shown by indices has to produce all possible C60O2 isomers; the second, C60F18, has to g…
