Anton Paar Finds Continued SAXsess | R&D Mag.

X-ray scattering is one of the most effective methods for determining the structure of materials on the nanoscale. Scattering is favored because it can reveal both the structure and chemical composition of solids or liquids without destroying the sample. Small-angle x-ray scattering (SAXS) is a widely used variation of this technique that fires a monochromatic beam through a sample. Most of the x-rays pass through the sample, but some x-rays scatter as they encounter inhomogeneities in the material.

For porous materials, SAXS is especially useful because x-rays are scattered as they pass through interfaces of domains within the sample. These domains can be solid, another type of liquid, or even a gas within the sample.

(etc.)

Very nifty – but I suppose it can’t be taken out to a building, a bridge, a dam or a levee to check the integrity of those materials. But, it sure needs to – or something that is based on the same principles. (my note)

About a teacher who taught Einstein -

Aurel Stodola From Wikipedia, the free encyclopedia

Aurel StodolaAurel StodolaBorn 10 May 18591859-05-10Liptovský Mikuláš, Austro-Hungarian EmpireDied 25 December 19421942-12-25 aged 83Zürich, SwitzerlandResting place Liptovský Mikuláš, SlovakiaResidence Slovakia, Switzerland

Known for technical thermodynamics gas turbine-powered electric generator

Awards Honorary degree of Leibniz University Hannover Grashof medal of Verein Deutscher Ingenieure Honorary degree of German Technical University of Brno Honorary degree of Charles University of Prague James Watt International MedalAurel Boleslav Stodola 10 May 1859 Liptovský Mikuláš, Austro-Hungarian Empire – 25 December 1942 Zürich, Switzerland

Aurel Stodola was an engineer, physicist, and inventor. He was an ethnic Slovak. He was a pioneer in the area of technical thermodynamics and its applications and published his book Die Dampfturbine the steam turbine in 1903. In addition to the thermodynamic issues involved in turbine design the book discussed aspects of fluid flow, vibration, stress analysis of plates, shells and rotating discs and stress concentrations at holes and fillets.[1]

Stodola was a professor of mechanical engineering at the Swiss Polytechnical Institute now ETH in Zurich. One of his students was Albert Einstein.[2] In 1892, Stodola founded the Laboratory for Energy Conversion.

Steam and Gas TurbinesStodola’s book Steam and Gas Turbines [3] was cited by Soviet rocket scientist Fridrikh Tsander in the 1920s. Published in English in 1927 and reprinted many times up to 1945, it was a basic reference for engineers working on the first generation of jet propulsion engines in the United States.[4]

Stodola worked closely with industries on the development of the first practical gas turbines, in particular Brown, Boveri & Cie, who built the first gas turbine-powered electric generator in 1939.[5]

Medical equipmentIn 1915-1916 Stodola collaborated with Ferdinand Sauerbruch a German surgeon to develop an advanced mechanically driven prosthetic arm. This collaboration marked one of the first documented examples of a surgeon and engineer merging efforts. Sauerbruch said, “Henceforth, surgeon, physiologist, and technician prosthetist/engineer will have to work together.”[6]

Honors 1905 – Honorary degree of Leibniz University Hannover 1908 – Grashof medal of Verein Deutscher Ingenieure Honorary degree of German Technical University of Brno 1929 – Honorary degree of Charles University of Prague 1941 – James Watt International MedalCorresponding member of French Academy of Sciences.

A brief and concise explanation of how the Fleischmann and Pons cold fusion experimental results came to be called quack science despite evidence to the contrary – (with sources) – 

http://en.wikiversity.org/wiki/Cold_fusion/The_Wikipedia_article/Comments_on_edits/Pathological_science

Source 9 does not mention “pathological science,” but is a report of the coming 2004 U.S. DoE review. It begins with: Cold fusion, briefly hailed as the silver-bullet solution to the world’s energy problems and since discarded to the same bin of quackery as paranormal phenomena and perpetual motion machines, will soon get a new hearing from Washington. This is a report in a reliable source, all right, but is fluff, general passing hyperbole, passive, with no attribution of who did the discarding.

Source 32 is not a reliable source, it appears to be a single individual’s private account of the meeting, attending with a group from General Electric Research, and does not mention “pathological science” either. It contains the following information about Morrison:

Evidence of a new phase in liquid hydrogen

February 25, 2010 By Miranda Marquit

http://www.physorg.com/news186310440.html

One of the most significant things Tamblyn and Bonev discovered through their simulations, from an astrophysics standpoint, is that equations describing the properties of hydrogen might need to be updated. “This should change the modeling going forward,” Tamblyn insists. “What we found in the liquid suggests what the solid might look like, and that can help determine some of its thermal and electronic properties.”

After running the simulations, Tamblyn and Bonev then had to analyze them. “We discovered an ordering in the liquid that accounts for some of the interesting characteristics of hydrogen, such as the fact that under certain conditions, liquid hydrogen is more dense than the solid. We also found that highly ordered packing explains properties related to dissociation that were previously not well understood.”

(etc.)

Information on the simulation efforts, as well as results and conclusions, are presented in : “Structure and Phase Boundaries of Compressed Liquid Hydrogen.”

Therefore, we are all agreed that new ways of developing and harnessing energy resources are desirable and much needed. The idea that the concept of fusion promises viable solutions to these energy needs has been around for a long, long time. The first such candidate for inclusion in this article is Sergei -

And this one – also from those search results -

http://www.scribd.com/doc/58342978/52/Piotr-Leonidovich-Kapitza-1894%E2%80%931984

A quote from the text linked above -

By early August Kapitza, at Rutherford’s suggestion, was studying how the energy of the alpha particle falls off at the end of its range. This project was brought to a successful conclusion with amazing rapidity. (etc.)

And this one -

He had to convince the authorities that his work lay primarily in pure rather than applied physics and that he could do nothing useful unless he had equipment and other facilities comparable with those he had enjoyed in Cambridge. Negotiations were begun to bring him what he required.

So Kapitza settled down to research again and within a year made his greatest discovery, the superfluidity of liquid helium. However, he lacked the freedom he had enjoyed in Cambridge. From the mid 1930s Soviet scientists found themselves increasingly cut off from their colleagues in other countries.

( .  . . )

Although he was no longer head of the Institute of Physical Problems, Kapitza retained his position and salary as a full academician and went to live at his country house at Nikolina Gora, where he managed to carry on scientific work while virtually under house arrest. Most of his effort went into building up a laboratory in various outhouses where, aided by his sons, particularly Sergei, he could continue experimental work, albeit only on relatively unexciting projects. While atomic physics elsewhere was moving rapidly ahead using particle accelerators and other new equipment, he was unable to contribute to this. Even after he had been reinstated in 1954 and could return to Moscow,he was still without  the facilities he needed for the kind of experimental work at which he excelled. Nevertheless, he began to think about the possibility of developing a defence against atomic bombs using extremely powerful microwave emissions. Later he transferred his attention to the problem of generating energy through nuclear fusion.

Also – this note from the article above – (about who Sergei is – one of two children born to Piotr and his wife, Anna) -

Two children were born in their Cambridge period: in 1928 Sergei, who became a distinguished physicist and successful popularizer of science for Soviet television, and three years later Andrei, who became a well-known Antarctic explorer and geographer.

Liquid Helium Research from above (my note – and check out the equations he used)

To describe the contributions made by Piotr Kapitza in physics as it pertains to this discussion of fusion -

(from a biographical sketch about him online)

In 1934 he returned to Moscow where he organized the Institute for Physical Problems at which he continued his research on strong magnetic fields, low temperature physics and cryogenics.

In 1939 he developed a new method for liquefaction of air with a lowpressure cycle using a special high-efficiency expansion turbine. In low temperature physics, Kapitsa began a series of experiments to study the properties of liquid helium that led to discovery of the superfluidity of helium in 1937 and in a series of papers investigated this new state of matter.

During the World War II Kapitsa was engaged in applied research on the production and use of oxygen that was produced using his low pressure expansion turbines, and organized and headed the Department of Oxygen Industry attached to the USSR Council of Ministers. Late in the 1940′s Kapitsa turned his attention to a totally new range of physical problems.

He invented high power microwave generators – planotron and nigotron (1950- 1955) and discovered a new kind of continuous high pressure plasma discharge with electron temperatures over a million K. Kapitsa is director of the Institute for Physical Problems.

Since 1957 he is a member of the Presidium of the USSR Academy of Sciences. He was one of the founders of the Moscow Physico-Technical Institute (MFTI), and is now head of the department of low temperature physics and cryogenics of MFTI and chairman of the Coordination Council of this teaching Institute. He is the editor-in-chief of the Journal of Experimental and Theoretical Physics and member of the Soviet National Committee of the Pugwash movement of scientists for peace and disarmament.

JTEC

Johnson Thermo-Electrochemical Converter System

The JTEC is an all solid-state engine that operates on the Ericsson cycle. Equivalent to Carnot, the Ericsson cycle offers the maximum theoretical efficiency available from an engine operating between two temperatures. The JTEC system utilizes the electro-chemical potential of hydrogen pressure applied across a proton conductive membrane (PCM). The membrane and a pair of electrodes form a Membrane Electrode Assembly (MEA) similar to those used in fuel cells.

On the high-pressure side of the MEA, hydrogen gas is oxidized resulting in the creation of protons and electrons. The pressure differential forces protons through the membrane causing the electrodes to conduct electrons through an external load. On the low-pressure side, the protons are reduced with the electrons to reform hydrogen gas. This process can also operate in reverse. If current is passed through the MEA a low-pressure gas can be “pumped” to a higher pressure.

The JTEC uses two membrane electrode assembly (MEA) stacks. One stack is coupled to a high temperature heat source and the other to a low temperature heat sink. Hydrogen circulates within the engine between the two MEA stacks via a counter flow regenerative heat exchanger. The engine does not require oxygen or a continuous fuel supply, only heat.

In nuclear physics, an energy amplifier is a novel type of nuclear power reactor, a subcritical reactor, in which an energetic particle beam is used to stimulate a reaction, which in turn releases enough energy to power the particle accelerator and leave an energy profit for power generation. The concept has more recently been referred to as an accelerator-driven system (ADS).
