Fuel cells--II. Propane and propylene on Adams' platinum catalyst
(Elsevier, 1964-12)
In order to control the quantity of previously adsorbed hydrogen in fuel electrodes to be used with hydrocarbons, the use of Adams' platinum catalyst was investigated. Preferred procedures for electrode preparation were ...
The elastic energy-momentum tensor in special relativity
(Elsevier, 1989-12)
We consider the standard nonrelativistic theory of a continuous, elastic medium with finite deformations, according to which the elastic energy is a function only of the state of strain, and the elastic stress tensor is ...
Alternative equations of motion for the radiating electron
(Springer-Verlag, 1995-02)
We have previously written down a simple second-order equation for the radiating electron and pointed out that its solutions are well behaved. A key feature of this equation is the presence of a term involving the time ...
A test of QCD based on 3-jet events from Z0 decays
(Elsevier, 1991-07-18)
We present a study of 43 000 3-jet events from Z0 boson decays. Both the measured jet energy distributions and the event orientation are reproduced by second order QCD. An alternative model with scalar gluons fails to ...
Comparison of high energy neutron-nucleus total cross sections with theory
(Elsevier, 1976-06-07)
A recent paper by Julius purports to show that previous estimates of the effect of inelastic screening on neutron-nucleus total cross sections are much too large. However, we show that most of this discrepancy is due to ...
A discrete ordinates solution of the Fokker-Planck equation characterizing charged particle transport
(Elsevier, 1980-11-01)
A formalism for obtaining a discrete ordinates solution of the time and space-dependent Fokker-Planck equation governing the transport of charged particles in multispecie plasmas is developed. In the absence of macroscopic ...
Rate processes on fractals: Theory, simulations, and experiments
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1986-01)
Heterogeneous kinetics are shown to differ drastically from homogeneous kinetics. For the elementary reaction A + A → products we show that the diffusion-limited reaction rate is proportional to t − h[A] 2 or to [A] x , ...
Evolution and impingement of an automotive fuel spray investigated with simultaneous Mie/LIF techniques
(Springer-Verlag, 2001-07)
The spatial and temporal evolution of an automotive hollow-cone-type spray was investigated with laser-based imaging diagnostics. Optical conditions of an IC engine were emulated with a test cell that was built from an ...
Ordered shapes in nonequilibrium growth
(Elsevier, 1989-09)
Patterns observed during nonequilibrium growth display complex ordering on many length scales. We focus on ordered patterns which reflect the interplay of microscopic and macroscopic dynamics. The fundamental morphologies ...
A millimeter wave technique for measuring ice thickness on the Space Shuttle's external tank
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1991-12)
The external fueltank of the Space Shuttle contains extremely lowtemperature propellents. A layer of material known as SOFI (Spray-On Foam Insulation) covering the outside of the fueltank provides thermal insulation between ...
