Make intergrowth, not war! Hierarchically organized MFI zeolites with micro-, meso-, and macroporosity (see scheme) in one structure were made by sequential intergrowth using a simple organic structure-directing agent (OSDA) without meso- or macroporogens. The use of an OSDA that imperfectly fits the zeolite framework generated very thin plates 90° rotational intergrowth.
Mount Sinabung, North Sumatra, Indonesia, erupted for the first time in 2010 and reactivated again 2013. The eruption started with a phreatic phase, changed to phreatomagmatic, then andesite lava appeared at summit crater late December Lava effusion continued has been associated partial complete collapses of complex, which successively generated pyroclastic density currents (PDCs). complex grew as dome developed into flow (lava extension stage). It extended up about 3 km horizontal runout...
Hexagonal perovskite-related oxides have garnered a great deal of research interest because their high oxide-ion conductivity at intermediate temperatures, with Ba7Nb4MoO20 being notable example. However, concomitant proton conduction in may cause decrease power efficiency when used as the electrolyte conventional solid oxide fuel cells. Here, through investigations transport and structural properties Ba7Nb4-xWxMoO20+x/2 (x = 0-0.25), we show that aliovalent substitution Nb5+ by W6+ not only...
Nematic liquid-crystalline (LC) physical gels suitable for light scattering electrooptical displays have been prepared from a nematic liquid crystal and low molecular weight gelator containing an oligo(L-isoleucine) moiety. The number of amino acid moieties the gelators has great effect on gelation ability behaviour LC gels. A having three L-isoleucine forms most efficiently. use leads to microphase separation where fibres with diameter ca. 30 nm finely disperse in crystals. Such structures...
Homeotropically oriented liquid-crystalline (LC) physical gels have been prepared from a room temperature nematic liquid crystal with negative dielectric anisotropy and low molecular weight gelator containing an L-lysine moiety. The self-aggregated fibres of the are formed by template effect homeotropically aligned LC media. These exhibit significant electrooptical switching in cells show high transparency electric field off-states. application fields induces light scattering turbid states...
Memorization of the alignment nematic liquid crystals in electric fields is achieved by incorporating small amounts self-assembled fibers into crystals. Hydrogen-bonded formed electrically aligned phases direct liquid-crystal after removal (see Figure and cover). Rewritable bistable nematics light-scattering transparent states have been a combination thermal stimuli.

Mikro-, meso- und makroporöse hierarchisch organisierte MFI-Zeolithe (siehe Schema) werden durch sequenzielles Verwachsen unter Verwendung eines einfachen organischen Struktur-dirigierenden Agens (OSDA), aber ohne Meso- oder Makroporogene gebildet. Das nicht perfekt mit dem Zeolithgerüst abgestimmte OSDA führte zur Bildung dünner Zeolithplättchen Verwachsung um 90°. As a service to our authors and readers, this journal provides supporting information supplied by the authors. Such materials...
The effects of the optical and thermal properties metal azo dyes on recording characteristics digital video disc-recordable (DVD-R) discs have been studied. A sharp threshold for decomposition dye assures a clear mark edge low jitter minimum length 0.4–0.44 µm. steep absorption at 635 nm side is also critical to high reflectivity fabricating edges. Following these guidelines, excellent 0.4 µm shortest are achieved with original dye.
The effective magneto–optical properties of novel nonanuclear Tb(III) complexes with Tb–O lattice (specifically, [Tb9(sal-R)16(μ-OH)10]+NO3–, where sal-R = alkyl salicylate (R −CH3 (Me), −C2H5 (Et), −C3H7 (Pr), or −C4H9 (Bu)) are reported. geometrical structures these were characterized using X-ray single-crystal analysis and shape-measure calculation. Optical Faraday rotation was observed in the visible region. Verdet constant per ion Tb9(sal-Me) complex is 150 times larger than that...
Abstract During prometaphase in mitosis, chromosomes are pushed toward the spindle equator. The chromokinesin Kid, also known as KIF22, moves along microtubules during prometaphase. Kid has long been considered a monomeric and non-processive motor, different from typical kinesins. In this study, we demonstrate that full-length forms homodimer processively microtubules. A conserved coiled-coil domain within stalk region of is not only capable formation, but required for processivity Kid....
We conduct waveform inversion to infer the three-dimensional (3-D) S-velocity structure in lowermost 400 km of mantle (the D′′ region) beneath Northern Pacific region. Our dataset consists about 20,000 transverse component broadband body-wave seismograms observed at North American stations for 131 intermediate and deep earthquakes which occurred western subduction use S, ScS, other phases that arrive between them. Resolution tests indicate our methods can resolve velocity target region with...
The first total synthesis of (+)-tanzawaic acid B, a natural polyketide bearing pentadienoic ester and octalin moiety, has been accomplished. synthetic improvement from previous conditions facilitated our gram-scale the chiral that possesses seven stereogenic centers is core skeleton almost all tanzawaic family.
Light amplification in DNA systems is a promising technique for efficient and compact photonics devices the future. Since highly fluorescent properties hemicyanine dyes are caused by interaction with or DNA-complex, their effects on basic optical were elaborated phases of solution solid films prepared two methods. Results absorption fluorescence characteristics showed that strongest light emission was achieved DNA-CTMA (cetyltrimethylammonium) rather than direct coupling to bare DNA. Laser...
Micro devices have been attracting attention accompanying industrial development in recent years. Higher-level microprocessing technique to produce them is demanded. The purpose of this study establish the novel satisfy 3 functions: sub-μm process resolution, 3-dimensional flexibility and rapidity. This report proposed a nano-stereolithography method using evanescent light instead propagating order achieve required functions. However, there are some important problems exposing curing because...
We have studied the high-speed performance at speeds of 3.5 m/s–14.0 m/s digital video disc recordable (DVD-R) discs which contain metal azo dyes. Good recording sensitivity and good mark jitter with carrier-to-noise ratio (C/N) > 50 dB lengths less than 0.40 µm were demonstrated over 10 due to high responses Furthermore, by introducing write strategy pulse trains, difference between could be completely eliminated excellent a value 8% level has been achieved 7.0 minimum length around 0.4 µm.
Light scattering electrooptic behavior has been examined for liquid-crystalline physical gels consisting of a room temperature nematic liquid crystal and amino acid gelators. Electrooptic properties the depend on morphologies hydrogen-bonded aggregates. We show that comprising randomly dispersed networks have potentials light materials.
