Petrological and geochemical constraints on tectonic settings of the Late Carboniferous-Early Permian, Central Junggar, China

open access: yesJournal of Natural Gas Geoscience, 2020
It is assumed that the central part of Junggar underwent continuous deposition from the Mesozoic to Cenozoic, but few data are available from deep well to support this hypothesis.

Carboniferous algaflora in the Urals and its stratigrafical meaning

open access: yesЛитосфера, 2016
In the Urals Carboniferous 11 algae zones allowing to make interregional and intercontinental correlation of coeval deposits are established by author. For more fractional dividing of carbonate profiles on algoflora for the first time akmezones have been

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
