The activation of hydrogen by excited mercury atoms [PDF]

, 1925
That mercury atoms excited by absorption of the line 2537Å are able to activate various kinds of atoms by collisions of the second kind has been shown in several different ways.

H$_2$ dissociation over Au-nanowires and the fractional conductance quantum

, 2005
The dissociation of H$_2$ molecules on stretched Au nanowires and its effect on the nanowire conductance are analyzed using a combination of Density Functional (DFT) total energy calculations and non-equilibrium Keldish-Green function methods.

Segmented phase of ultraviolet (UV) curable thermoset polyurethanes-graphite (TPU-G) composites [PDF]

, 2019
Segmented thermoset polymeric materials properties mainly classified through its carbonyl hydrogen bonding. The addition of graphite particle loading in polymeric materials tailored the functional characteristic of the composites. Therefore, the carbonyl

The Separation of the Two Types of Iodine Molecule and the Photochemical Reaction of Gaseous Iodine with Hexene [PDF]

, 1930
Soon after Dennison had deduced from the specific-heat curve that ordinary hydrogen gas consists of a mixture of two types of molecule, the so called ortho and para hydrogen, a similar state of affairs in the case of iodine gas was demonstrated by direct

An embedding scheme for the Dirac equation

, 2004
An embedding scheme is developed for the Dirac Hamiltonian H. Dividing space into regions I and II separated by surface S, an expression is derived for the expectation value of H which makes explicit reference to a trial function defined in I alone, with

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
