Status and future perspectives of airborne magnetic gradiometry
Airborne magnetics is one of the most used methods in metalliferous mining geophysics. Full tensor magnetic gradiometer instruments overcome many of the limitations of total field and vector magnetic field...
PublicationsCarrier Mobility in Semiconductors at Very Low Temperatures †
Carrier mobilities and concentrations were measured for different p- and n-type silicon materials in the temperature range 0.3–300 K. Simulations show that experimentally determined carrier mobilities...
PublicationsWhat optical fiber modes reveal: group velocity and effective index for external perturbations
Precise control of fiber modes and their dispersion is essential, particularly for fields such as nonlinear frequency conversion or biosensing, both of which often require extensive and time-consuming...
PublicationsUltrahigh-aspect-ratio light cages: fabrication limits and tolerances of free-standing 3D nanoprinted waveguides
Three-dimensional laser nanoprinting represents a unique approach for implementing on-chip hollow-core waveguides. Here we discuss the fabrication characteristics of the light cage geometry arising from...
PublicationsUltralong tracking of fast diffusing nano-objects inside nano-fluidic channel enhanced microstructured optical fiber
Nanoparticle tracking analysis (NTA) represents one essential technology to characterize diffusing nanoscale objects. Herein, uncovering dynamic processes and high-precision measurements requires tracks...
PublicationsLongitudinally thickness-controlled nanofilms on exposed core fibres enabling spectrally flattened supercontinuum generation
Nonlinear frequency conversion is a pathway to unlock undiscovered physics and implement tailored light sources for spectroscopy or medicine. A key challenge is the establishment of spectrally flat outputs,...
PublicationsNanograting-Enhanced Optical Fibers for Visible and Infrared Light Collection at Large Input Angles
The efficient incoupling of light into particular fibers at large angles is essential for a multitude of applications; however, this is difficult to achieve with commonly used fibers due to low numerical...
PublicationsTargeted delivery of a phosphoinositide 3-kinase γ inhibitor to restore organ function in sepsis
Jaundice, the clinical hallmark of infection-associated liver dysfunction, reflects altered membrane organization of the canalicular pole of hepatocytes and portends poor outcomes. Mice lacking phosphoinositide...
PublicationsMolecular characterization of Staphylococcus aureus isolated from human and food samples in northern Algeria
Staphylococcus aureus is a commensal resident of the skin and nasal cavities of humans and can cause various infections. Some toxigenic strains can contaminate food matrices and cause foodborne intoxications....
PublicationsThe Pheno- and Genotypic Characterization of Porcine Escherichia coli Isolates
Escherichia (E.) coli is the main causative pathogen of neonatal and post-weaning diarrhea and edema disease in swine production. There is a significant health concern due to an increasing number of human...
