Apr 20 2015 · There is great interest in DNA nanotechnology but its use has been limited to aqueous or substantially hydrated media. The first assembly of a DNA nanostructure in a water‐free solvent namely a low‐volatility biocompatible deep‐eutectic solvent composed of a 4 1 mixture of glycerol and choline chloride (glycholine) is now described.

• Nanostructure of Deep Eutectic Solvents at Graphite

Atomic force microscopy (AFM) density functional theory (DFT) calculations and contact angle measurements have been used to investigate the liquid–highly ordered pyrolytic graphite (HOPG) electrode interface for three deep eutectic solvents (DESs) as a function of applied potential. The DESs examined are 1 2 mixtures of choline chloride and urea (ChCl urea) choline chloride and ethylene

• Solidification of Al-Si alloys

Al-Si alloys differ from our "standard" phase diagram in that aluminium has zero solid solubility in silicon at any temperature. This means that there is no beta phase and so this phase is "replaced" by pure silicon (you can think of it as a beta phase which consists only of silicon).. So for Al-Si alloys the eutectic composition is a structure of alpha Si rather than alpha beta.

The electrodeposition process is influenced by the structure and dynamics of the solvent at the solid–liquid interface. Therefore the nanoscale structure of the interface between a silicon substrate and deep eutectic solvent (choline chloride–ethylene glycol) was studied by neutron reflectometry (NR) and molecular dynamics (MD) simulations.

The maximum solubility of Si in Al occurs at the eutectic temperature and is 1.65 wt. . At least up to the late 1950 s the eutectic was believed to be at 11.6 wt. Si.

Aluminium-silicon alloys form a eutectic at 11.7 wt silicon the eutectic temperature being 577 o C. This represents a typical composition for a casting alloy because it has the lowest possible melting temperature. Al-12Si wt alloys are therefore common. Al-12Si (low magnification unetched).

A eutectic system (/ j uː ˈ t ɛ k t ɪ k / yoo-TEK-tik) from the Greek "εύ" (eu = well) and "τήξις" (tēxis = melting) is a homogeneous mixture of substances that melts or solidifies at a single temperature that is lower than the melting point of any of the constituents.
