To generate a photonic nanojet outside a high refractive index microsphere illuminated by a Gaussian beam
A non-resonant, concentrated, narrow beam of light emerging from an illuminated microlens is called a photonic nanojet (PNJ). According to currently prevailing opinion, microspheres and microcylinders...
Publikationen | 04.01.2023Dogs as carriers of virulent and resistant genotypes of Clostridioides difficile
While previous research on zoonotic transmission of community-acquired Clostridioides difficile infection (CA-CDI) focused on food-producing animals, the present study aimed to investigate whether dogs...
