The Sierra Nevada mountain range consists of a vast array of different geologic features. One of these features is in the form of what are known as roof pendants. Roof pendants span through the central and southern portions of the eastern Sierra Nevada. Representing the geologic history of the Sierra Nevada mountain range in California, metamorphic roof pendants offer a glimpse into the past. T...

Helical polymer brushes with a preferred-handed helix-sense composed of a poly(phenylacetylene) backbone and poly(phenyl isocyanate) pendants are synthesized. The helix-sense of the backbone is effectively controlled by the helical chirality of the pendants, which is triggered by an optically active group introduced at the pendant terminal.

Fertility and abundance are important themes of ancient Mesopotamian texts and images. The goddess Inanna and her consort Dumuzi personify these ideas in texts of the second millennium B.C.E. Excavated by Leonard Woolley in the 1920s, the Royal Cemetery at Ur dates to the mid third millennium B.C.E. Among the tombs, that of Queen Puabi yielded many ornaments of gold, carnelian, and lapis. Some ...

Polythiophene (PT) is one of the widely used donor materials for solution-processable polymer solar cells (PSCs). Much progress in PT-based PSCs can be attributed to the design of novel PTs exhibiting intense and broad visible absorption with high charge carrier mobility to increase short-circuit current density (Jsc), along with low-lying highest occupied molecular orbital (HOMO) levels to ach...

Genesis and morphology of soil pendants in Quaternary landforms of Pabranagat Valley, Nevada

Herein we reported three new platinum(ii)-triarylpyridines complexes with peralkylated ammonium pendants that strongly stabilize G-quadruplex DNA.

A series of chiral aryl amide compounds bearing peptide pendants have been investigated as low molecular weight gelators. A mechanistic study reveals that complementary hydrogen bonding from peptide pendants is the main driving force for the formation of organogels. This new class of organogels can exhibit multi-stimuli-responsive behavior upon applying (1) thermal, (2) pH, (3) enantiomeric pur...

A small change in chemical structure causes a remarkable influence on the stereostructure stability and mutarotational rate of helical vinyl polymers bearing laterally attached p-terphenyl pendants with an achiral butoxy terminal and a chiral galactosyloxy terminal.
