Nanodiamonds containing negatively charged nitrogen vacancy centers (${\text{NV}}^{\ensuremath{-}}$) have applications as localized sensors in biological materials and been proposed a platform to probe the macroscopic limits of spatial superposition quantum nature gravity. A key requirement for these is obtain nanodiamonds ${\text{NV}}^{\ensuremath{-}}$ with long spin coherence times. Using milling fabricate processes full 3D volume bulk material at once, unlike etching pillars, but has, up...
Levitated nanodiamonds containing negatively charged nitrogen-vacancy centers (${\text{NV}}^{-}$) have been proposed as a platform to generate macroscopic spatial superpositions. Requirements for this include having long ${\text{NV}}^{-}$ spin coherence time, which necessitates formulating dynamical decoupling strategy in the regular flips do not cancel growth of superposition through Stern-Gerlach effect an inhomogeneous magnetic field. Here, we propose scheme place $250$-nm-diameter...
The negatively charged nitrogen-vacancy center (NVC) in diamond has been utilized a wide variety of sensing applications. long spin coherence and relaxation times (${T}_{2}^{\ensuremath{\ast}}$, ${T}_{2}$ ${T}_{1}$) the at room temperature are crucial to this, as they often limit sensitivity. Using NVCs nanodiamonds allows for operations environments inaccessible bulk diamond, such intracellular sensing. We report single isotopically purified polycrystalline ball-milled nanodiamonds....
There is significant interest in potential experimental tests of macroscopic quantum effects, both to test modifications theory and probe the nature gravity. A proposed platform with which generate required spatial superposition a nanodiamond containing negatively charged nitrogen vacancy (${\text{NV}}^{-}$) centre. In this review, methods fabricate nanodiamonds ${\text{NV}}^{-}$ suitable for these applications are discussed. The probes limits presented along spin physics centre relevant those tests.
The negatively charged nitrogen-vacancy centre (NV$^-$) in diamond has been utilized a wide variety of sensing applications. centre's long spin coherence and relaxation times ($T_2^*$, $T_2$ $T_1$) at room temperature are crucial to this, as they often limit sensitivity. Using NV$^-$ centres nanodiamonds allows for operations environments inaccessible bulk diamond, such intracellular sensing. We report single isotopically-purified polycrystalline ball-milled nanodiamonds. spin-locking pulse...
<h3>Background</h3> Transient epileptic amnesia (TEA) is a clinical presentation of focal epilepsy from temporal origin characterised by transient episodes anterograde without other aspects cognitive impairment. It rare diagnosis which requires evidence epilepsy, such as epileptiform abnormalities on electroencephalogram (EEG). We present case 76-year-old female with prolonged episode TEA. <h3>Case Description</h3> A previously well presented to tertiary hospital emergency department...
