Molecular recognition in olfaction

Advances in Physics: X, 2017
The mechanism by which the chemical identity of odourants is established by olfactory receptors is a matter of intense debate. Here we present an overview of recent ideas and data with a view to summarising what is known, and what has yet to be ...

Interaction between Heavy Water and Single-Strand DNA: A SERS Study

Molecules, 2022
The structure and function of biological macromolecules change due to intermolecular deuterium bond formation or deuterium substitution with environmental D2O. In this study, surface-enhanced Raman spectroscopy (SERS) was used to detect interaction sites

Corrections to deuterium hyperfine structure due to deuteron excitations

, 2003
We consider the corrections to deuterium hyperfine structure originating from the two-photon exchange between electron and deuteron, with the deuteron excitations in the intermediate states. In particular, the motion of the two intermediate nucleons as a

The Deuterium to Hydrogen Abundance Ratio Towards the QSO SDSS1558-0031 [PDF]

, 2006
We present a measurement of the D/H abundance ratio in a metal-poor damped Lyman alpha (DLA) system along the sightline of QSO SDSS1558-0031. The DLA system is at redshift z = 2.70262, has a neutral column density of log(NHI)=20.67+/-0.05 cm^2, and a gas-

Mapping Nanoscale Protein‐Corona Kinetics of DoE‐Optimized Perfluorocarbon Encapsulated‐PLGA Nanoparticles by In Situ, Time‐Resolved Synchrotron SAXS

Advanced Healthcare Materials, EarlyView.
A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.

Hydrogelation via Supramolecular Copolymerization of Structural Water within Adaptive Metal–Organic Fibers

Advanced Materials, EarlyView.
Structural water is harnessed as an active co‐monomer to drive supramolecular polymerization in bulk water. Zinc(II) Salphen complexes confine water molecules to form hollow, metal–organic nanofibers that assemble into adaptive hydrogels with thermoresponsive mechanics and selective chiral recognition.

Migratory connectivity of Blue-winged Teal: risk implications for avian influenza virus introduction to Cuba

Frontiers in Bird Science
In recent years, the complex evolution of the highly pathogenic avian influenza (HPAI) situation reflects a change in the eco-epidemiology of the causative agent which, among other demands, renews the need for better understanding of the connectivity ...

Measurement of the strong interaction induced shift and width of the 1s state of kaonic deuterium at J-PARC [PDF]

, 2015
The antikaon-nucleon interaction close to threshold provides crucial information on the interplay between spontaneous and explicit chiral symmetry breaking in low-energy QCD.

Explosives Detection Using Deuterium-Deuterium Neutron Generator [PDF]

Journal of Nuclear Science and Technology, 2008
Gamma spectra of general and explosive materials were obtained by using the developed neutron induced prompt gamma-ray spectrometry system containing a neutron generator, where the neutron source was created from a deuterium-deuterium reaction, and they were examined to establish whether the samples were explosives or not by using the pattern ...
