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

Diamond codes are a new example of so-called cooperating codes. Cooperating codes are used extensively for protecting data stored on magnetic or optical media. A well-known example is a product code. In that case, codewords are \(n_1\) by \(n_2\) matrices in which each column is in a code \(C_1\) of length \(n_1\) and each row is in a code \(C_2\) of ...

Tin-vacancy in diamonds for luminescent thermometry
Applied Physics Letters, 2018Color centers in diamonds have shown promising potential for luminescent thermometry. So far, the nitrogen-vacancy (NV) color center has demonstrated a high sensitivity for optical temperature monitoring in biological systems.

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.

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.

Science, 1984
Radiation from a Q-switched YAG laser, focused on the (100) face of a single crystal diamond anvil in a high-pressure diamond cell, caused a portion of the diamond anvil face to melt. Potassium bromide mixed with graphite was under pressure between the anvils when melting occurred.

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
