Commercial NIRS May Not Detect Hemispheric Regional Disparity in Continuously Measured COx/COx-a: An Exploratory Healthy and Cranial Trauma Time-Series Analysis [PDF]

open access: yesBioengineering
Continuous metrics of cerebral autoregulation (CA) assessment have been developed using various multimodal cerebral physiological monitoring devices. However, CA regional disparity remains unclear in states of health and disease.

NIR-to-visible and NIR-to-NIR upconversion in lanthanide doped nanocrystalline GdOF with trigonal structure [PDF]

open access: yesOptical Materials, 2011
Abstract Codoped Er 3+ /Yb 3+ , Tm 3+ /Yb 3+ , Ho 3+ /Yb 3+ and triply doped Er 3+ /Tm 3+ /Yb 3+ gadolinium oxyfluoride nanoparticles were prepared in aqueous solution by a simple coprecipitation method and a suitable heat treatment at 500 °C. From the experimental X-Ray powder diffraction patterns, a Rietveld analysis was carried out and it was ...

NIR‐NIR‐Aufkonvertierung in molekularen Chrom‐Ytterbium‐Salzen [PDF]

open access: yesAngewandte Chemie, 2020
AbstractPhotonen‐Aufkonvertierung in hetero‐oligonuklearen, Metallkomplex‐Architekturen mit organischen Liganden ist ein interessantes, aber bisher selten beobachtetes Phänomen, trotz des großen Potentials sowohl aus Sicht der Grundlagenforschung als auch aus der Anwendungsperspektive. Nun wurde ein neues photonisches Material aus molekularen Chrom(III)
