Portable infrared laser spectroscopy for on-site mycotoxin analysis
(Universität Ulm, 2017-03-09)
Mycotoxins are toxic secondary metabolites of fungi that spoil food, and severely impact human health (e.g., causing cancer). Therefore, the rapid determination of mycotoxin contamination includingdeoxynivalenolandaflato ...
Mid-infrared fiberoptic evanescent field spectroscopy for in-situ monitoring of tetrahydrofuran hydrate formation and dissociation
(Universität Ulm, 2017-01-03)
Tetrahydrofuran is a relevant auxiliary molecule when storing carbon dioxide or hydrocarbons as gas hydrates. The present study demonstrates the application of in situ mid-infrared fiber-optic evanescent field absorption ...
Boron-doped diamond modified with gold nanoparticles for the characterization of bovine serum albumin protein
(Universität Ulm, 2017-07)
Boron-doped diamond (BDD) has been modified with bare gold nanoparticles (AuNPs) for the investigation of bovine serum albumin (BSA) protein films. First, the BDD electrode was amino- terminated via silanization with ...
Non-equilibrium relations for bounded rational decision-making in changing environments
(Universität Ulm, 2017-12-21)
Living organisms from single cells to humans need to adapt continuously to respond to changes in their environment. The process of behavioural adaptation can be thought of as improving decision-making performance according ...
Chem/bio sensing with non-classical light and integrated photonics
(Universität Ulm, 2017-12-06)
Modern quantum technology currently experiences extensive advances in applicability in communications, cryptography, computing, metrology and lithography. Harnessing this technology platform for chem/bio sensing scenarios ...
Towards enhanced optical sensor performance: SEIRA and SERS with plasmonic nanostars
(Universität Ulm, 2017-02-08)
We report the preparation and characterization of plasmonic chip-based systems comprising self-assembled gold nanostars at silicon substrates that enable concomitantly enhanced Raman (surface enhanced Raman spectroscopy; ...
Surface enhanced infrared absorption spectroscopy based on gold nanostars and spherical nanoparticles
(Universität Ulm, 2017-10-16)
Plasmonic anisotropic nanoparticles possess a number of hot spots on their surface due to the presence of sharp edges, tips or vertices, leading to a high electric field strength surrounding the nanostructures. In this ...
Longitudinal trajectories of metabolic control from childhood to young adulthood in type 1 diabetes from a large German/Austrian registry: A groupbased modelling approach
(Universität Ulm, 2017-03-01)
OBJECTIVE: Worsening of glycemic control in type 1 diabetes during puberty is a common observation. However, HbA1c remains stable or even improves for some youths. The aim is to identify distinct patterns of glycemic ...
Implementation and Sex-specific Analysis of Students' Attitudes Toward a Longitudinal, Gender-specific Medical Curriculum - A Pilot Study
(Universität Ulm, 2017)
Retinal Artery Occlusions
