Circularly polarized microwaves for magnetic resonance study in the GHz range: application to nitrogen-vacancy in diamonds

, 2015
The ability to create time-dependent magnetic fields of controlled polarization is essential for many experiments with magnetic resonance. We describe a microstrip circuit that allows us to generate strong magnetic field at microwave frequencies with ...

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

Molecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

NV center creation in diamond by local CW laser irradiation of shallow implanted nitrogen

New Journal of Physics
A novel creation procedure for the nitrogen-vacancy (NV) center in diamond is investigated. After shallow nitrogen implantation, a continuous-wave laser is used to induce NV formation, while simultaneously exciting fluorescence to enable live observation.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Hybrid nanodiamond quantum sensors enabled by volume phase transitions of hydrogels

Nature Communications, 2018
Nitrogen-vacancy (NV) centers in diamonds are used for quantum sensing but NV centers are not sensitive to parameters such as temperature, pressure and biomolecules.

Microwave-free magnetometry with nitrogen-vacancy centers in diamond

, 2016
We use magnetic-field-dependent features in the photoluminescence of negatively charged nitrogen-vacancy centers to measure magnetic fields without the use of microwaves.

Eddy-Current Imaging with Nitrogen-Vacancy Centers in Diamond [PDF]

Physical Review Applied, 2019
We demonstrate microwave-free eddy-current imaging using nitrogen-vacancy centers in diamond. By detecting the eddy-current induced magnetic field of conductive samples, we can distinguish between different materials and shapes and identify structural defects.

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

Advanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Statistical investigations on nitrogen-vacancy center creation

Applied Physics Letters, 2014
Quantum information technologies require networks of interacting defect bits. Color centers, especially the nitrogen vacancy (NV−) center in diamond, represent one promising avenue, toward the realisation of such devices. The most successful technique for creating NV− in diamond is ion implantation followed by annealing. Previous experiments have shown
