Journal of Magnetic Resonance, 2023
The resolution of magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectra remains bounded by the spinning frequency, which is limited by the material strength of MAS rotors. Since diamond is capable of withstanding 1.5-2.5x greater MAS frequencies, compared to state-of-the art zirconia, we fabricated rotors from single crystal diamond. When

Raman spectroscopy of diamond and doped diamond
Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2004The optimization of diamond films as valuable engineering materials for a wide variety of applications has required the development of robust methods for their characterization. Of the many methods used, Raman microscopy is perhaps the most valuable because it provides readily distinguishable signatures of each of the different forms of carbon (e.g ...

Perception, 2010
A brightness illusion and transparency effects are described for configurations comprising alternating black and white bars on which are superimposed mid-luminance shapes (diamonds and hexagons). The resulting phenomena are predictable by Anderson's ‘scission theory’, which is thus given further support.

AbstractWe defend the thesis that every necessarily true proposition is always true. Since not every proposition that is always true is necessarily true, our thesis is at odds with theories of modality and time, such as those of Kit Fine and David Kaplan, which posit a fundamental symmetry between modal and tense operators.

Conflict Diamonds? Not Every Diamond Is a Blood Diamond
2009This chapter focuses on one of the hottest issues for the diamond industry: conflict (or ‘blood’) diamonds. The generations-old symbolic significance of a diamond as a stone of love and wealth suddenly began to change into a stone of war, misery, and hatred. Based on a theoretical approach to moral panic, analysed here in this chapter is the process of

Diamond array of diamond elements
2016 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC), 2016The radiation characteristics of a diamond array (DA) of diamond elements are calculated using the method of moments. It is found that the maximum gain for the DA is higher than that for a conventional grid array antenna (GAA). It is also found that the frequency bandwidth of the gain for the DA is slightly narrower than that for the conventional GAA.

Journal of Visual Languages & Computing, 2015
A number of approaches for logical reasoning with diagrams have been proposed. This paper considers the question, how the expressiveness of such systems can be raised without losing the visual power of less expressive diagrams. The antagonism between expressiveness and diagrammatic simplicity is coped with by a set of jointly exhaustive and contrary ...

Chapter 79 diamonds are diamonds
2012Kate and Alice, as they drew near to their journey’s end, were both a little flurried, and I cannot but own that there was cause for nervousness. Kate Vavasor was to meet Mr Grey for the first time.
