Low storage efficiency, resulting from the wasted energy needed to overcome the high enthalpy of hydride formation and elevated energy barriers to hydrogen release. 

In the case of ions, the attractive electrostatic potential almost always dominates vibrational quenching at thermal energies, because of the charge-induced dipole force for nonpolar molecules and the even stronger charge-dipole interaction for polar molecules. The case of the above-mentioned N2(n)-He system is an exception, as = 0.017 eV is so small that the minimum of k falls below room temperature, and thus only the increase due to repulsive forces is observed in experiments at elevated energies. 

Until 1973, when the oil embargo occurred, energy was regarded as an uncontrollable overhead item, but rapid escalation in energy costs changed this perception and elevated energy to the status of a... 

In the nearest future, one should expeet wide commercialization of hybrid supercapacitors of the C/Pb02, C/Ni02, C/Mn02, C/ECP, and other supercapacitor types with elevated energy density of the order of 40-50 Wh/kg, that is, with the energy density not lower than that of conventional batteries, but with a much higher cyclability. 

Other acids with preservative action include benzoic acid (CgH COOH), the use of which has increased in recent years in animal feed. In its chemically pure form, this acid is a white granular or crystalline powder, however the main form used is sodium benzoate, due to its higher solubility in water. Benzoate inhibits yeasts more than moulds or bacteria. The undissociated form of benzoic acid, as well as sodium benzoate, is essential to its antimicrobial activity, as both are soluble in cell walls and facilitate proton leakage across membranes. This elevates energy requirements to maintain the internal cell pH. 

Dming episodes of enhanced seiche activity in Rotterdam Harbor, the surface elevation energy spectrmn at sea in the frequency band corresponding to the typical eigenfrequencies in Rotterdam Harbor basins, say, 0.1 2.0 mHz, varies with frequency (/) approximately as An episode of enhanced wave energy at sea in... 

The main disadvantage of the photochemical method is that the radicals obtained usually display an elevated energy store (excited or hot radicals). This makes them unsuitable for the study of the chemical properties of the common (thermalized) radicals and measures ensuring pre-thermalization of hot radicals have to be taken (such as conducting experiments in gases diluted with an inert gas). 

The high reactivity of electronically excited species is usually ascribed to their elevated energy (which is essential for endothermic reactions) and also to spin conservation (the Wigner rule). The great difference in the rate constants for the reactions of CH2 and CH2 with N2 and CH4, which are exothermic reactions occurring without violation of the Wigner rule, is probably due to different potential energy surfaces. 

The excess energy of the primary photochemical decomposition products at the moment of their generation makes them more reactive than the same species in the state of thermal equilibrium with the ambient gas. Particles with an elevated energy store are referred to as hot particles. 

Plotted are the QCT results of Boonenberg and Mayne [26] which are based on the SLTH-PES at low Efr they obviously manifest a competition between the orientational and the energy effect, but at the two elevated energies the energy effect appears undisturbed. The model functions (dashed lines) are calculated using r rjj=0.796 deduced fiom the SLTH-PES and ti=2,6 (v=0 -> v=l) in a QCT study Toennies et al. [27] find an enhancement of il=2 at Ejj.=0.8 eV.

F /2 = kinetic energy per unit mass, (KE)/m gh = elevation energy per unit mass As an example, consider the water clock used by Galileo to measure time (Fig. 5.14). This shows the path of a fluid particle from a point on the upper surface (1) that is maintained at a constant elevation (Aj) to a point (2) just beyond the orifice in the side of the vessel. Substituting into Eq. (5.15), and noting thatp- =Pj, Pi = Pi, and Fj = 0 ...
