High Efficiency Detection of Argon Scintillation Light of 128nm Using LAAPDs

, 2005
The possibility of efficient collection and detection of vacuum ultraviolet light as emitted by argon, krypton, and xenon gas is studied. Absolute quantum efficiencies of large area avalanche photodiodes (LAAPDs) are derived at these wavelengths.

Inhalability and Bioactivity of Spray‐Dried versus Pressurized Gas eXpanded Liquid Technology‐Processed Yeast Beta‐Glucan Microparticles for Anti‐Fibrotic Therapies

Advanced Healthcare Materials, EarlyView.
PGXTEC) liquid technology is utilized to develop highly respirable yeast beta‐glucan (YBG) microparticles for the treatment of pulmonary fibrosis. Compared to conventionally processed spray‐dried YBG, PGXTEC‐YBG exhibits greatly improved aerodynamic properties, enhanced pro‐fibrotic macrophage uptake, and effective downregulation of pro‐fibrotic ...

Tritium radioactivity estimation in cement mortar by heat-extraction and liquid scintillation counting

Nuclear Engineering and Technology, 2021
Tritium extraction from radioactively contaminated cement mortar samples was performed using heating and liquid scintillation counting methods. Tritiated water molecules (HTO) can be present in contaminated water along with water molecules (H2O).

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

Advanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Determining the activity of 241Pu by liquid scintillation counting [PDF]

, 2018
Liquid scintillation counting (LSC) is one of the most widely used methods for determining the activity of 241Pu. One of the main challenges of this counting method is the efficiency calibration of the system for the low beta energies of 241Pu (E max=20 ...
