Identification of permissive amber suppression sites for efficient non-canonical amino acid incorporation in mammalian cells

Nucleic Acids Research, 2021
The genetic code of mammalian cells can be expanded to allow the incorporation of non-canonical amino acids (ncAAs) by suppressing in-frame amber stop codons (UAG) with an orthogonal pyrrolysyl-tRNA synthetase (PylRS)/tRNAPylCUA (PylT) pair. However, the

Cyclic production of biocompatible few-layer graphene ink with in-line shear-mixing for inkjet-printed electrodes and Li-ion energy storage

npj 2D Materials and Applications, 2022
The scalable production of two-dimensional (2D) materials is needed to accelerate their adoption to industry. In this work, we present a low-cost in-line and enclosed process of exfoliation based on high-shear mixing to create aqueous dispersions of few ...

High capacity silicon anodes enabled by MXene viscous aqueous ink

Nature Communications, 2019
Developing thick electrodes could enable high-energy-density Li-ion batteries, however, above a critical thickness, the mass transport issues become dominating.

Spin-phonon decoherence in solid-state paramagnetic defects from first principles

npj Computational Materials, 2023
Paramagnetic defects in diamond and hexagonal boron nitride possess a combination of spin and optical properties that make them prototypical solid-state qubits. Despite the coherence of these spin qubits being critically limited by spin-phonon relaxation,

Wheeler’s dilemma revisited: first Oecophylla–Lasius syninclusion and other ants syninclusions in the Bitterfeld amber (late Eocene)

, 2021
The first syninclusions of extant tropical and Holarctic ant genera are reported from Bitterfeld amber: the tropical Oecophylla F. Smith (O. brischkei Mayr, 1868) with the Holarctic genus Lasius F. (four workers of L.

High-throughput bandstructure simulations of van der Waals hetero-bilayers formed by 1T and 2H monolayers

npj 2D Materials and Applications, 2021
Vertically stacked van der Waals heterostructures made of two-dimensional compounds are almost an infinite playground for the fabrication of nano-engineered materials for the most diverse applications.

Stingless bees in Miocene amber of southeastern China (Hymenoptera: Apidae)

Journal of Melittology, 2021
Among the many inclusions from the exceptionally rich fossiliferous amber of Zhangpu, China (Middle Miocene: Langhian), stingless bees (Apinae: Meliponini) are particularly common, analogous to the merely slightly older amber sites of Mexico and the ...

An in situ and ex situ TEM study into the oxidation of titanium (IV) sulphide

npj 2D Materials and Applications, 2017
TiS2 oxidation: moisture is the critical element preventing environmental stability The degradation dynamics of TiS2 reveal that the flakes oxidise in water and atmosphere, pointing towards moisture as the key driving force.
