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

open access: yesnpj 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,

Characteristics of Photoluminescence and Raman Spectra, and the Occurrence of Trace Elements of Blue Amber from Dominican Republic and Mexico

open access: yesYankuang ceshi, 2022
BACKGROUND Blue amber is mainly produced in the Dominican Republic, Mexico and Myanmar. Generally speaking, the formation mechanism, composition and spectral characteristics of blue amber are closely related to its specific geographical environment ...

Understanding the effect of MXene in a TMO/MXene hybrid catalyst for the oxygen evolution reaction

open access: yesnpj 2D Materials and Applications, 2023
Very recently, it has been reported that mixed transition metal oxide (TMO)/MXene catalysts show improved performance over TMO only catalysts for the oxygen evolution reaction (OER). However, the reasoning behind this observation is unknown. In this work

The first fossil cyphophthalmid harvestman from Baltic amber [PDF]

open access: yes, 2011
The first fossil cyphophthalmid harvestman (Opiliones: Cyphophthalmi) from Palaeogene (Eocene) Baltic amber is described. This is only the third fossil example of this basal harvestman lineage; the others being from the probably slightly younger ...

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

open access: yesnpj 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.

Creating Active Device Materials for Nanoelectronics Using Block Copolymer Lithography

open access: yesNanomaterials, 2017
The prolonged and aggressive nature of scaling to augment the performance of silicon integrated circuits (ICs) and the technical challenges and costs associated with this has led to the study of alternative materials that can use processing schemes ...

Fringe tracking performance monitoring: FINITO at VLTI

open access: yes, 2012
Since April 2011, realtime fringe tracking data are recorded simultaneously with data from the VLTI/AMBER interferometric beam combiner. Not only this offers possibilities to post-process AMBER reduced data to obtain more accurate interferometric ...

Universal scaling relations for the rational design of molecular water oxidation catalysts with near-zero overpotential

open access: yesNature Communications, 2019
While water electrolysis affords hydrogen as a carbon-neutral fuel, the oxygen evolution half-reaction limits overall performances. Here, authors examine molecular catalysts and their water oxidation mechanisms via computational methods.

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

open access: yesnpj 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.

Development of Hydroxyapatite Coatings for Orthopaedic Implants from Colloidal Solutions: Part 2—Detailed Characterisation of the Coatings and Their Growth Mechanism

open access: yesNanomaterials, 2023
This study is the second part of a two-part study whereby supersaturated solutions of calcium and phosphate ions generate well-defined hydroxyapatite coatings for orthopaedic implants. An ‘ideal’ process solution is selected from Part 1, and the detailed
