“…26 exploring a nanostructure with a large specific surface area and a high superhydrophobic/superoleophilic surface is a critical step. As a carbon-based material, nanodiamonds (NDs) are widely used in precision processing, 27 electronic devices, 28 sensors, 29,30 and other fields 31 due to their low cost, large-scale production, large specific surface area, rich surface chemistry, and high hardness. When it comes to oil-stained adsorption materials, ND powders have many advantages.…”

Fabrication of absorbent materials foroil/water separation is an important ecological pursuit for oil spill clean-up and organic pollutants' removal. In this study, nanodiamonds (NDs), a promising member of the carbon family, were functionally modified by the covalent linking of octadecylamine (ODA). Subsequently, the superhydrophobic sponge with hierarchical microstructures was fabricated by embedding ND-ODA into a melamine sponge (MS) skeleton via a simple immersion-drying process. The as-prepared sponge (ND-ODA@ PDMS@MS) showed superhydrophobic properties with a water contact angle of 155 ± 2°. For various oils and organic solvents, ND-ODA@PDMS@MS possesses excellent absorption capacity (26.65−55.64 g/g) and oil/water separation efficiency (above 98.6%). Furthermore, the adsorption capacity to crude oil remained relatively stable in highly acidic, alkaline, and salty conditions, ensuring the application in the clean-up of industrial oily sewages and marine oil spills. Besides absorbing oil for a single time, ND-ODA@PDMS@MS also exhibited satisfactory performance in continuous oil/water separation. Therefore, this work provides a facile strategy to produce robust and efficient absorbent materials for oil/water separation in large-scale oil and organic solvent cleanups.

“…[29] Because it has a wide range of prospective applications, for example, nonreciprocal transmission and memory of nonclassical fields, [30,31] EIT has been successfully realized in many systems, such as gas-phase atoms, [32,33] photosynthetic energy transfer, [34,35] metamaterial, [36] superconducting system, [37] and NV center in diamond. [38] On the other hand, nitrogen-vacancy (NV) center in diamond is an intriguing platform for quantum information processing [39][40][41] and quantum sensing. [42,43] NV center is a pair of point defects at adjacent sites in diamond crystal.…”

Optical Nonreciprocity in Rotating Diamond with Nitrogen‐Vacancy Color Centers

A method to realize optical nonreciprocity in rotating nano‐diamond with nitrogen‐vacancy (NV) centers is theoretically proposed here. Because of the relative motion of the NV center with respect to the propagating fields, the frequencies of the fields are shifted due to the Doppler effect. When the control and probe fields are incident to the NV center from the same direction, the two‐photon resonance still holds as the Doppler shifts of the two fields are the same. Thus, due to the electromagnetically‐induced transparency, the probe light can pass through the NV center nearly without absorption. However, when the two fields propagate in opposite directions, the probe light cannot effectively pass through the NV center as a result of the breakdown of two‐photon resonance.

“…However, due to the noise inevitably induced from the thermal bath, as well as the limitation of the nonlinear interaction, generating the substantial pondermotive squeezing light is still a challenge for the optomechanical system [9]. The levitated optomechanical system has raised widespread interest in macroscopic quantum superposition [16][17][18], quantum time crystals [19,20], and quantum information processing [21]. The squeezing has been studied in the levitated optomechanical system, in which the nano-particle is optically levitated and coupled with a cavity field [22].…”

Squeezing light is a critical resource in both fundamental physics and precision measurement. Squeezing light has been generated through optical-parametric amplification inside an optical resonator. However, preparing the squeezing light in an optomechanical system is still a challenge for the thermal noise inevitably coupled to the system. We consider an optically levitated nano-particle in a bichromatic cavity, in which two cavity modes could be excited by the scattering photons of the dual tweezers, respectively. Based on the coherent scattering mechanism, the ultra-strong coupling between the cavity field and the torsional motion of nano-particle could be achieved for the current experimental conditions. With the back-action of the optically levitated nano-particle, the broad single-mode squeezing light can be realized in the bad cavity regime. Even at room temperature, the single-mode light can be squeezed for more than 17 dB, which is far beyond the 3 dB limit. The two-mode squeezing light can also be generated, if the optical tweezers contain two frequencies, one is on the red sideband of the cavity mode, the other is on the blue sideband. The two-mode squeezing can be maximized near the boundary of the system stable regime and is sensitive to both the cavity decay rate and the power of the optical tweezers.
