How well electron transport works in furfural biogas

September 13, 2017

Furfural is a promising candidate in the quest for alternative biofuels. The combustion industries are very interested in what could become a potential new type of fuel derived from atmospheric-plasma treatment of biomass. But before the gas can be considered for use on a large scale, it is essential to understand its energy characteristics. Now, a Spanish team has published its findings on the gas's energy efficiency in EPJ D. Ana Lozano from the Institute of Fundamental Physics in Madrid, Spain, and colleagues studied an electron beam entering a cell filled with furfural gas molecules to study its scattering characteristics, providing the first accurate experimental evaluation of the effectiveness of the interaction between electron and gas particles--via electron scattering cross-section measurements-- for selected electron beam impact energies.

The authors applied a magnetic field along the direction of the electron beam entering a cell filled with furfural gas. They observed that the magnetic field converts any potential deflection due to scattering between the electrons and furfural gas molecules into an energy loss in the forward direction of the magnetic field.

Further, the team used a device called a retarding field analyser to effectively discriminate between scattered and unscattered electrons, which allowed them to accurately measure the energy of transmitted electrons as a function of the furfural gas pressure in the scattering chamber. They then used these experimental results as input parameters to create a simulation of the transport of 10 million electrons with an initial energy of 10 eV through gaseous furfural.

This led to the establishment of a benchmark evaluation of the total low-energy electron scattering cross-sections from furfural and energy loss estimates for selected energies (7, 10 and 20 eV).

Magnetic Fields: Expanding American Abstraction, 1960s to Today
by Valerie Cassel Oliver (Author), Lowery Stokes Sims (Author), Erin Dziedzic (Editor), Melissa Messina (Editor)

In the history of American art, the contributions of African American artists to the development of abstraction have been largely overlooked.

Magnetic Fields aims to change this perspective by focusing on nonrepresentational work by women artists of color, presenting a more complete presentation of American abstraction than has previously been offered.

Intergenerational in scope, Magnetic Fields includes more than 20 artists born between 1891 and 1981, among them Lilian Thomas Burwell, Mildred Thompson, Candida Alvarez, Betty Blayton, Nanette... View Details


Earth's Magnetic Field Secrets: An Illusion Mixed With Reality
by Dennis Brooks (Author)

The Old Theory Until now, there was only one theory regarding the source of Earth's magnetic field, which is the internal dynamo theory. This theory was accepted because it offered the best explanation at the time. Also, much research has been done to support the theory. According to the internal dynamo theory, a dynamo near the center of the planet generates the current that produces the magnetic field. This dynamo would be in the liquid outer core of the planet. It would produce the magnetic axis and project it from the planet. The axis would expand and spread the magnetic field around the... View Details

Know Your Magnetic Field: Change Your Thinking, Change Your Life.

“We mortals operate on wave lengths from the Universal, the Trinity; these are our life waves. They are distributed, one wave from each of the ruling suns. Each of our waves is on a set length or frequency; the blending of the three waves is the Power. This sets the pattern of our individual frequency. It is the source of our personality, our identity and it is as distinct and individual as our own finger-prints. “On the strength of our wave we, similar to a planet, operate by our magnetic field through the medium and receive the knowledge we need from the vast pool of wisdom.

Reconnection of Magnetic Fields: Magnetohydrodynamics and Collisionless Theory and Observations
by J. Birn (Editor), E. R. Priest (Editor)

The reconnection of magnetic fields is one of the most fascinating processes in plasma physics, responsible for phenomena such as solar flares and magnetospheric substorms. The concept of reconnection has developed through recent advances in exploring the magnetospheres of the Sun and Earth through theory, computer simulations and spacecraft observations. The great challenge in understanding it stems from balancing the large volumes of plasma and magnetic fields involved with the energy release with the physical mechanism which relies on the strongly localized behavior of charged particles....

This book deals with the particular case of reversals of the Earth's magnetic field. These have played a major role in the development of plate tectonics and in establishing a geological time scale. The magnetism of rocks is discussed in some detail with a warning of possible misinterpretations of the record. The latest observational results and theories are reviewed with special attention to the structure and geometry of the transition field. Changing conditions at the core-mantle boundary, their effect on reversals, the generation of plumes and the possible correlation of reversals with... View Details
