Nature, 2020 Self-assembling colloidal particles in the cubic diamond crystal structure could potentially be used to make materials with a photonic bandgap1-3. Such materials are beneficial because they suppress spontaneous emission of light1 and are valued for their applications as optical waveguides, filters and laser resonators4, for improving light-harvesting ...

Selection of reagent compositions for modifying spectral characteristics of weakly and anomalously luminescent diamonds in the process of X-ray luminescence separation [PDF]
Journal of Mining and Metallurgy. Section A: Mining, 2023 The feasibility of targeted modification of the spectral properties of weakly and anomalously luminescent diamonds by modifying reagents containing luminophores based on sulfides and zinc orthosilicate, characterized by medium and low deviation of the ...

IMA Journal of Applied Mathematics, 2016 For materials science, diamond crystals are almost unrivaled for hardness and a range of other properties. Yet, when simply abstracting the carbon bonding structure as a geometric bar-and-joint periodic framework, it is far from rigid. We study the geometric deformations of this type of framework in arbitrary dimension d, with particular regard to the ...

Insight into a Fenton-like Reaction Using Nanodiamond Based Relaxometry
Nanomaterials, 2022 Copper has several biological functions, but also some toxicity, as it can act as a catalyst for oxidative damage to tissues. This is especially relevant in the presence of H2O2, a by-product of oxygen metabolism.

Avoiding Diamonds in Desynchronization [PDF]
Science of Computer Programming, 2013 The design of concurrent systems often assumes synchronous communication between different parts of a system. When system components are physically apart, this assumption becomes inappropriate. Desynchronisation is a technique that aims to implement a synchronous design in an asynchronous manner by placing buffers between the components of the ...

Observation of Surface Microstructure of HPHT Synthetic Diamond Crystals and Genesis Discussion
Yankuang ceshi, 2019 BACKGROUND As the world's largest producer of synthetic diamonds, China accounts for more than 90% of the world's total production, of which high pressure-high temperature (HPHT) synthetic diamonds are dominant.
