Reaction Pathways in Catechol/Primary Amine Mixtures: A Window on Crosslinking Chemistry. [PDF]

PLoS ONE, 2016
Catechol chemistry is used as a crosslinking tool abundantly in both natural organisms (e.g. mussels, sandcastle worms) and synthetic systems to achieve the desired mechanical properties.

Networking chemical robots for reaction multitasking [PDF]

, 2018
The development of the internet of things has led to an explosion in the number of networked devices capable of control and computing. However, whilst common place in remote sensing, these approaches have not impacted chemistry due to difficulty in ...

Nighttime removal of NOx in the summer marine boundary layer [PDF]

, 2004
The nitrate radical, NO3, and dinitrogen pentoxide, N2O5, are two important components of nitrogen oxides that occur predominantly at night in the lower troposphere. Because a large fraction of NO2 reacts to form NO3 and N2O5 during the course of a night,

OH+ in Diffuse Molecular Clouds [PDF]

, 2013
Near ultraviolet observations of OH+ and OH in diffuse molecular clouds reveal a preference for different environments. The dominant absorption feature in OH+ arises from a main component seen in CH+ (that with the highest CH+/CH column density ratio ...

Linking stress-driven microstructural evolution in nanocrystalline aluminium with grain boundary doping of oxygen

Nature Communications, 2016
Nanocrystalline metals are ultra-strong because of the large fraction of material at the grain boundaries, but this also leads to instability under applied loads. Here, the authors deepen our understanding of this by linking stress-driven motion of grain

Tuning the shear thickening of suspensions through surface roughness and physico-chemical interactions

Physical Review Research, 2022
Shear thickening denotes the reversible increase in viscosity of a suspension of rigid particles under external shear. This ubiquitous phenomenon has been documented in a broad variety of multiphase particulate systems, while its microscopic origin has ...

Analysis of auto-ignition of heated hydrogen-air mixtures with different detailed reaction mechanisms [PDF]

, 2011
Auto-ignition processes of hydrogen, diluted with nitrogen, in heated air are numerically investigated by means of an unsteady laminar flamelet approach in mixture fraction space. The focus is on the auto-ignition delay time and the most reactive mixture

Multifrequency radiation hydrodynamics simulations of H2 line emission in primordial, star-forming clouds [PDF]

, 2014
We investigate the collapse of primordial gas in a minihalo with three-dimensional radiation hydrodynamics simulations that accurately model the transfer of H2 line emission.
