Mass spectrometric analyses of the trimeric His-tagged complex indicated that it is composed of FcpA and FcpE polypeptides. It is confirmed here that a trimer is the basic organizational unit selleck of Fcps in P. tricornutum. From circular dichroism spectra, it is proposed that the organization of the pigments on the polypeptide

backbone of Fcps is a conserved feature in the case of chlorophyll a/c containing algae.”
“The spherical silica powders were prepared by using an oxygen-acetylene flame method. After spheroidization, a scanning electron microscope investigation revealed that the spheroidization efficiency of the powder was nearly 100%, XRD patterns indicated that the raw crystal silica became amorphous silica. In

this study, composites of spherical silica and an epoxy resin were prepared with a homogenizer, followed by a stepwise thermal curing process. The thermal stability and thermal degradation behavior of the composites were studied by a thermogravimetric analyzer. Meanwhile, the effects of spherical silica powder on dynamic mechanical, coefficient of thermal expansion, and mechanical properties of epoxy/silica composites were also investigated. The Hippo pathway inhibitor initial decomposition temperature and mechanical properties increased significantly after adding the spherical silica into the composite. The maximum properties of thermal stability and mechanical properties were observed when spherical silica accounted for 30% of the system.

The thermal expansion had been significantly reduced by the addition of silica. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 121: 648-653, 2011″
“The polaritons in a two-dimensional artificial ionic-type crystal have been proposed and experimentally demonstrated from the two-dimensional periodically poled LiTaO3. In this artificially micro-structured materials, the anisotropic piezoelectric coefficients and the two-dimensional symmetric result in strong and complex couplings of the incident electromagnetic waves and the two-dimensional superlattice find more vibrations. We studied the dielectric anomalies, the coupling and transforming between two ordinary polariton modes etc., which reveal that, by engineering the ferroelectric domain’s distribution, the artificial ionic-type crystal may establish a new member of meta-materials, and will facilitate access to the device applications such as multi-directional and frequency transducers.(c) 2011 American Institute of Physics.

“An investigation was carried out on the application of dilute chitosan solutions modified by a tyrosinase-catalyzed reaction with 3,4-dihydroxyphenetylamine (dopamine) to the adhesion of low-density polyethylene (LDPE) and high-density polyethylene (HDPE) plates photografted with carboxyl-group-containing hydrophilic monomers, such as methacrylic acid (MAA) and acrylic acid (AA).
