Autofluorescent organelles within the retinal pigment epithelium in human donor eyes with and without age-related macular degeneration
PURPOSE. Human retinal pigment epithelium (RPE) cells contain lipofuscin, melanolipofuscin, and melanosome organelles that impact clinical autofluorescence (AF) imaging. Here, we quantified the effect...
Publications | 21.01.2022Metrological characterization of a high temperature hybrid sensor using thermal radiation and calibrated sapphire fiber Bragg grating for process monitoring in harsh environments
Fiber Bragg gratings inscribed in single crystalline multimode sapphire fibers (S-FBG) are suitable for monitoring applications in harsh environments up to 1900 _C. Despite many approaches to optimize...
Publications | 01.02.2022Active repair of a dinuclear photocatalyst for visible-light-driven hydrogen production
The molecular apparatus behind biological photosynthesis retains its long-term functionality through enzymatic repair. However, bioinspired molecular devices designed for artificial photosynthesis, consisting...
Publications | 11.02.2022Electron beam co-deposition of thermoelectric BiSb thin films from two separate targets
We present the deposition of thin Bi1 xSbx-films, by electron-beam co-evaporation as an advantageous alternative method to thermal evaporation. Similar thermoelectric properties of the layers could...
Publications | 21.01.2022FTIR multispectral imaging of P/Al-doped silica glass preforms prepared by MCVD in combination with high temperature evaporation of AlCl3
For high power fiber lasers, codoping with Al, P or both is necessary to prevent rare earth (RE) clustering in the silica network of the laser active core material. Here, we present a complementary infrared...
Publications | 17.02.2022The effect of layer thickness and immobilization chemistry on the detection of CRP in LSPR assays
The immobilization of a capture molecule represents a crucial step for effective usage of gold nanoparticles in localized surface plasmon resonance (LSPR)-based bioanalytics. Depending on the immobilization...
Publications | 26.01.2022Integrated optically pumped magnetometer for measurements within Earth’s magnetic field
We present a portable optically pumped magnetometer instrument for ultrasensitive measurements within the Earth’s magnetic field. The central part of the system is a sensor head operating a MEMSbased...

Smart residual sum of squares allows correction of systematic errors
Determining the true value of a physical or metrological quantity is essential in statistics. In the absence of bias, the median or arithmetic mean can be excellent estimates of this true value. Otherwise,...
