Liquid Hydrogen Bubble Chambers [PDF]
Review of Scientific Instruments, 1955 Chambers 2½ inches and 4 inches in diameter have been constructed of brass with pyrex ports and sealed with lead-wire gaskets. Metal walls and a copper heat leak eliminate the need for a surrounding pressurized bath. The required fast-pulsing techniques and use of a heat regenerator are described in detail.

A liquid-hydrogen Čerenkov counter [PDF]
Nuclear Instruments and Methods, 1964 Abstract Two models of a liquid-hydrogen Cerenkov counter have been constructed and tested. The first served as a prototype and was used to demonstrate the feasibility of the design concept and to show that liquid hydrogen does not give scintillation light of intensity comparable to that of Cerenkov light.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Hydrogen Road Transport Analysis in the Energy System: A Case Study for Germany through 2050
Energies, 2021 Carbon-free transportation is envisaged by means of fuel cell electric vehicles (FCEV) propelled by hydrogen that originates from renewably electricity. However, there is a spatial and temporal gap in the production and demand of hydrogen.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

H2-powered aviation – Design and economics of green LH2 supply for airports
Energy Conversion and Management: X, 2023 The economic competitiveness of hydrogen-powered aviation highly depends on the supply costs of green liquid hydrogen to enable true-zero CO2 flying. This study uses non-linear energy system optimization to analyze three main liquid hydrogen (LH2) supply

ON THE MICROSCOPIC STRUCTURE OF LIQUID HYDROGENS [PDF]
Condensed Matter Physics, 2001 Among the quantum liquids, the hydrogens cover an interesting position between liquid helium, where quantum exchange gives rise to the macroscopic phenomenon of superfluidity, and neon, where quantum effects are relatively small, so that its features can be evaluated by perturbation methods with reference to a classical system.
