From atomic mechanisms to multiscale and machine learning assisted modeling: understanding the sintering limit in high purity refractory metals

Materials & Design
High-purity refractory metals are widely used in aerospace, nuclear energy, and semiconductor applications. During sintering, however, these materials frequently exhibit kinetic slowdown and densification stagnation at high relative densities.

Prospects for identifying strategic metals deposits in the Russian Arctic [PDF]

Arctic: Ecology and Economy, 2017
Mineral deposits are important in the economy of the Russian Arctic. In addition to the petroleum and gas, the resources of PGE minerals and gold, nickel and titanium are more than 10% of global significance. Meanwhile, the most arctic territory is out of availability of detailed geological and geophysical data due to severe climatic situation.

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

FEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...
