A RUDN University chemist has synthesized fluorescent compounds with "merry-go-round" molecules that can be used to create economical displays with organic LEDs (OLEDs). The nucleus of these molecules is a triangle of silver or copper atoms, and organic elements are bound to it through phosphorus atoms that rotate around them. This molecular geometry may allow researchers to create more efficient OLED screens. The article is published in Inorganic Chemistry.

Author(s): Matthew D. Frye and Jeremy M. Hutson This paper investigates the time delay around Feshbach resonances in ultracold collisions. Far above threshold, the time delay shows a simple Lorentzian peak as a function of both energy and field, but close to threshold it is proportional to the scattering length and so has a pole-like oscillation as a function of field. For narrow resonances, the energy of the crossover between these behaviors is proportional to the square of the resonance strength sres. For resonances that are wide or have large background scattering lengths, the behavior is more complicated.

While detection at ultralow concentrations with conventional midinfrared plasmonic biosensors is challenging, toroidal metamaterial technology has enabled the development of ultrasensitive, label-free recognition and detection of low-weight biological objects at femto- and attomolar concentrations. (Consider 1 cm3 of solution containing just 602 solute molecules…or 1 mm3 containing just…how many?) This remarkable performance stems from the exquisite sensitivity of robustly squeezed electromagnetic fields in the toroidal plasmonic metastructures.

17:03 Phys.orgMolecular dynamics simulation sheds new light on methane hydrate formation

In a paper published this week in PNAS, researchers at the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences and the Amsterdam Center for Multiscale Modeling provide atomistic insight in the formation of methane hydrates. On the basis of molecular dynamics simulations they explain how selection between competing methane hydrate polymorphs occurs, and how this might be generalized to other hydrates and molecular crystal formation.

Life uses 20 coded amino acids (CAAs) to construct proteins. This set was likely evolutionarily 'standardized' from smaller sets as organisms discovered how to make and encode them. Scientists modeled how the adaptive properties of the CAAs evolved over time. They found that sets containing even only a few CAAs were better than an enormous choice of alternatives, suggesting each time a modern CAA was discovered, it bootstrapped the set to include still more CAAs.

An international and interdisciplinary team working at the Earth-Life Science Institute (ELSI) at the Tokyo Institute of Technology has modeled the evolution of one of biology's most fundamental sets of building blocks and found that it may have special properties that helped bootstrap itself into its modern form.

Cells are the basic building blocks of life - and, as such, they have been the object of intense study since the invention of the optical microscope in the 17th century.
