This paper explores the optimal operation of a distributed ammonia production facility which is coupled with local renewable energy generation. The coupling of stochastic renewables with this flexible chemical process enables exchange of energy with the utility in a highly regulated and benign manner. In particular, we analyze the ability of this facility to operate economically under a market ...

A study of the energy accommodation of neon colliding with a crystalline self-assembled 1-decanethiol monolayer adsorbed on Au(111) is presented. The intensity and velocity dependencies of the scattered neon as a function of incident angle and energy were experimentally measured. Scattering calculations show good agreement with these results, which allows us to examine the detailed dynamics of ...

We study the energy flow due to the motion of topological solitons in nonlinear extended systems in the presence of damping and driving. The total field momentum contribution to the energy flux, which reduces the soliton motion to that of a point particle, is insufficient. We identify an additional exchange energy flux channel mediated by the spatial and temporal inhomogeneity of the system sta...

Equilibrium amide hydrogen exchange studies of barstar have been carried out at pH 6.7, 32 degrees C using one- and two-dimensional nuclear magnetic resonance. An unusually large fraction of the backbone amide hydrogens of barstar exchange too fast to be measured, and the exchange rates of only fifteen slow-exchanging amide sites including indole amides of two tryptophans could be measured in t...

Results of Perdew–Zunger self-interaction corrected (PZ-SIC) density functional theory calculations of the atomization energy of 35 molecules are compared to those of high-level quantum chemistry calculations. While the PBE functional, which is commonly used in calculations of condensed matter, is known to predict on average too high atomization energy (overbinding of the molecules), the applic...

Energy poverty at the household level is a serious hindrance to economic and social development, especially in off-grid, remote villages in the developing world. Some initiatives have sought to provide these households with resources such as renewable generation units and electric batteries to enable access to electricity. At present, these resources are operated in isolation, fulfilling indivi...

We demonstrate energy exchange between two filament-forming femtosecond laser beams in liquid methanol. Our results are consistent with those of previous works documenting coupling between filaments in air; in addition, we identify an unreported phenomenon in which the direction of energy exchange oscillates at increments in the relative pulse delay equal to an optical period (2.6 fs). Energy t...
