Supercooling of Liquid Hydrogen
Physical Review Letters, 1986We describe experiments that we have performed with droplets of supercooled liquid ${\mathrm{H}}_{2}$ in the temperature range down to 10.6 K. We have measured the nucleation rate for the production of the solid phase. Using this result, we discuss the prospects for the experimental production of superfluid ${\mathrm{H}}_{2}$.

Microscopic structure of liquid hydrogen
Journal of Physics: Condensed Matter, 2003Hydrogen makes the most simple molecular liquid. Nonetheless, due to several different reasons, measuring its microscopic structure has been one of the most challenging tasks in neutron diffraction experiments. The recent development of the modern pulsed neutron sources triggered a renewed experimental interest which, in turn, brought to new knowledge ...

Liquid Hydrogen Fueled Diesel Automobile with Liquid Hydrogen Pump
1986A passenger car with 2-L four-stroke turbo-diesel engine was converted into a LH2-fueled vehicle. The hydrogen fuel system consisted of a LH2tank and a high pressure LH2pump. The engine used 8 MPa H2 late direct cylinder injection and hot surface ignition.

Experiments with supercooled liquid hydrogen
Physical Review B, 1987We report on experiments performed with droplets of supercooled liquid ${\mathrm{H}}_{2}$, maintained in a state of neutral buoyancy in pressurized $^{4}\mathrm{He}$ fluid. We have measured the nucleation rate for solidification as a function of temperature, and have observed and analyzed several interesting hydrodynamic effects relating to the motion ...

Journal of Physics: Condensed Matter, 2000
When average one-particle densities are spatially uniform at a microscopic level the state is considered to be a homogeneous liquid. A prescription is required for the basic dynamical elements involved in the averaging itself, and for hydrogen, at low densities and temperatures, these are the familiar hydrogen molecules.

Hydrogen-Bonded Liquid Crystal Nanocomposites
Langmuir, 2016Nanoparticle-liquid crystal (NP-LC) composites based on hydrogen bonding were explored using a model system. The ligand shells of 3 nm diameter zirconium dioxide nanoparticles (ZrO2 NPs) were varied to control their interaction with 4-n-hexylbenzoic acid (6BA).

Hydrogen bonding in ionic liquids
Chemical Society Reviews, 2015Doubly ionic H-bonds are not a rare or esoteric form of the H-bond, rather they constitute a broad class found commonly within ionic liquids, which has yet to be fully explored.

Hydrogen Motions in Liquid Hydrogen Fluoride
The Journal of Chemical Physics, 1969The inelastic scattering of cold neutrons by liquid and solid HF has been used to study the low-frequency modes of motion. On melting a pronounced reduction in amplitude and increase in width is observed in the near-inelastic spectra. Analysis of the angular dependence of this effect suggests that it is due to rotational rather than translational modes
