## Abstract Detailed characteristics of excitonic emission in diamond have been studied by theoretical considerations taking into account the indirect semiconductor properties to calculate precise simulated spectra of the excitonic emission. The simulated excitonic emission spectra agree well with

## Abstract The Editor's Choice [1] is a theoretical study of the excitonic emission properties in diamond, in particular with regard to possible BoseβEinstein condensation (BEC). The cover picture shows a simple phase diagram for electronβhole pairs in dependence on their density and temperature.
The characteristics of the surfaces of worn diamond segments in circular saws for the sawing of granite have been investigated. A scanning electron microscope and a toolmaker's microscope were used to examine the worn surfaces, and radial sawblade wear and grinding ratio during sawing were measured.
