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

Angewandte 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)

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

Advanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Two⁃dimensional correlation infrared spectroscopy and hyperspectral imaging to detect the changes of polysaccharide during the drying process of Polygonatum sibiricum

Shipin yu jixie
ObjectiveTo study the changes of polysaccharide in the drying process of "one steam and one preparation" of Polygonatum sibiricum.MethodsThe slices were steamed by atmospheric pressure water isolation steaming, and then dried by heat pump at 60 ℃.

Study of Transparency of Pigments to Near Infrared

Proceedings, 2019
We describe the results of a systematic study of reflectance of pigments traditionally used in Mexican cultural treasures on different substrates. We observe that underline drawings may be most easily detected in NIR when the pigment transmissivity in ...

Near-infrared jet emission in the microquasar XTE J1550-564 [PDF]

, 2011
Context: Microquasars are accreting Galactic sources that are also observed to launch relativistic jets. A key signature of the ejection is non-thermal radio emission. The level of this jet component at high frequencies is still poorly constrained. Aims:

Engineered Mycelial Scaffolds With Tunable Ultraviolet Protection, Wettability, Thermal Stability, and Spatial Mechanics

Advanced Engineering Materials, EarlyView.
Fungal mycelia grown into biodegradable scaffolds and infused with titania nanoparticles show enhanced ultraviolet shielding, thermal protection, and surface nonwettability. Properties were tuned by drying methods, revealing structure–function relationships.

Nondestructive Measurement Method of Leaf Area Index Using Near-infrared Radiation and Photosynthetically Active Radiation Transmitted through a Leafy Vegetable Canopy

HortScience, 2022
Because the leaf area index (LAI) is an essential parameter for understanding the structure and growth status of plant canopies, nondestructive and continuous estimation methods have been required.

The Stellar Populations of Starburst Galaxies Through near infrared spectroscopy [PDF]

, 2008
We study the central (inner few hundred parsecs) stellar populations of four starburst galaxies (NGC34, NGC1614, NGC3310 and NGC7714) in the near-infrared (NIR), from 0.8 to 2.4microns, by fitting combinations of stellar population models of various ages
