Its a remarkable thing that when a scientist, or in this case a group of scientists, announce a genuine basic scientific or engineering breakthrough that opens the door to a new avenue of research and poses all sorts of questions about the nature of matter, journalists and The Daily Telegraph in particular get completely the wrong end of the stick and others then decide that the scientists are worthless freaks.
The piece in the Telegraph is so riddled with inaccuracies and false conflations that it should be used as some sort of example of how not to do it in journalism schools. Lets pick it apart and see what he got wrong.
Japan creates synthetic version of rare earth metal palladium
WRONG
PALLADIUM IS NOT A RARE EARTH METAL THE RARE EARTHS ARE A SPECIAL GROUP OF ELEMENTS THAT HAVE BEEN IN THE NEWS RECENTLY. PALLADIUM IS A METAL THAT IS RARE ON EARTH, ITS A DIFFERENT THING.
AND THE JAPANESE SCIENTISTS DID NOT CLAIM TO CREATE A SYNTHETIC PALLADIUM, THOUGH THEY DO STATE THAT THEIR ACHIEVEMENT IS ‘AKIN TO MODERN ALCHEMY’
IN THEIR CONCLUSIONS THE GROUP SAYS
“we conclude that the Ag50Rh50 solid-solution alloy has an electronic structure similar to that of Pd (palladium)”.
THE USE OF THE WORD ‘SYNTHETIC’ BY RYALL IMPLIES A NEW MATERIAL WAS FORMED WHEN IN FACT WHAT WAS BEING CREATED WAS A VERY FINE MISTED MIXTURE THAT OTHER MOLECULES REACTED TO AS IF THAT MIXTURE WAS PURE SOLID PALLADIUM.
Japanese scientists have developed a synthetic version of the rare earth metal palladium, a breakthrough that it is hoped will eventually reduce industry’s reliance on exports from China.
WRONG
JAPANESE INDUSTRY IS NOT RELIANT ON CHINESE EXPORTS FOR SUPPLIES OF PALLADIUM. MOST PALLADIUM COMES FROM THE SAME DEPOSITS AS PLATINUM. RUSSIAN AND SOUTH AFRICAN MINES PROVIDE OVER 75% OF THE WORLD’S PALLADIUM. CHINA’S MAIN INTEREST IN PALLADIUM IS THROUGH RECYCLING OF WASTE CATALYTIC CONVERTORS. IT HAS NO MINES OF ITS OWN AND DOES NOT SIGNIFICANTLY INFLUENCE PALLADIUM PRICE OR AVAILABILITY.

Researchers at Kyoto University achieved the world-first by uniting molecules of rhodium and silver, which do not naturally combine, through the fusion of ultramicroscopic particles of the metals after they had been reduced to a fine solution spray.
WRONG
THE USE OF ‘UNITING’ AND ‘FUSION’ IMPLIES THAT THERE WAS A FORCED BONDING BETWEEN THE METALS. IF YOU READ THE PAPER IT IS APPARENT THAT THE NANO-PARTICULATE SPRAY IS A SIMPLE MIX WITH A FEW ADDED CHEMICALS TO ALLOW THE NANO-PARTICULATE TO FLOAT TOGETHER WITHOUT STICKING TO THE CONTAINER. THE WIERD EFFECTS WERE SEEN WHERE NANO-PARTICLES HAPPENED TO SETTLE ADJACENT TO EACH OTHER. A TEMPERATURE OF 170C IS NOWHERE NEAR ENOUGH FOR NORMAL METALLIC ALLOYING TO TAKE PLACE, EVEN IF THE METALS USED WERE MISCIBLE, SO SOME SORT OF QUANTUM STATE DIFFUSION LOOKS A GOOD BET (NOT BEING A QUANTUM METALLURGIST THAT’S AS FAR AS I’M STRETCHING).
THE WORD ‘ULTRAMICROSCOPIC’ IS A TRANSLATION THAT HAS NO MEANING IN TODAY’S SCIENCE AND THE SCALE AT WHICH THIS WORK WAS BEING CARRIED OUT COMMONLY USES THE TERM ‘NANO’ TO DENOTE THE SMALL SCALE.
Each particle is a mere 10 nanometers in diameter, Professor Hiroshi Kitagawa told the Yomiuri newspaper, but the new alloy has the same properties as palladium.
WRONG – SEE ABOVE.
ALSO THE PAPER MAKES IT PLAIN THAT PROPERTIES SUCH AS HYDROGEN STORAGE ARE VERY DIFFERENT.
Exports from China of palladium – which is a crucial part of next-generation engines and serves to clean exhaust gases and absorb high levels of hydrogen – were abruptly halted in the wake of a territorial dispute between Beijing and China.
WRONG
THE DISPUTE HAD NOTHING TO DO WITH PALLADIUM AND THERE WAS NO CONFIRMATION FROM CHINA THAT ANY DISRUPTION OF MINERALS SUPPLY TOOK PLACE. JAPANESE OFFICIALS WERE PRE-EMPTING ANY SUCH MOVE BY CHINA BY LODGING A FORMAL DIPLOMATIC PROTEST AT THE RHETORIC BEING USED OVER THE BORDER DISPUTE AND THREATENED TO APPROACH THE WTO REGARDING ANY FUTURE DISRUPTION OF SUPPLY OF RARE EARTH ELEMENTS, NOT PALLADIUM. WHICH AS WE HAVE STATED IS NOT IMPORTED INTO JAPAN FROM CHINA IN ANY VOLUME.
In September, a Chinese fishing vessel operating within Japan’s exclusive economic zone around the Senkaku Islands, the very southernmost tip of Okinawa Prefecture, rammed a Japanese Coast Guard patrol vessel.
The captain of the trawler was arrested, causing an outcry in Beijing, which claims the uninhabited islands as sovereign Chinese territory.
The Chinese fisherman was eventually released without being charged, but not before Beijing imposed a ban on shipments to Japanese firms.
MOSTLY OK BUT A LITTLE WRONG
NO BAN WAS ISSUED. THE CHINESE WERE MORE SUBTLE AND SIMPLY DELAYED SHIPMENTS IN PORT AND CUSTOMS CLEARANCE.
As well as Japan’s automobile industry, rare earth materials such as yttrium, praseodymium and thulium are important for companies here producing everything from infrared lasers to alloys for aerospace components, batteries, ceramic capacitors and parts for computer memory chips.
OK – BUT PALLADIUM IS NOT A RARE EARTH ELEMENT. THE ERROR IS MADE THREE TIMES IN ORDER TO JUSTIFY THE STORY WITHOUT IT THE SCIENCE IS PROBABLY TOO ESOTERIC FOR TELEGRAPH READERS TO BE INTERESTED IN. LAZY AND GREEDY.
The scientists said the new alloy will be difficult to produce commercially at this point but the production process is expected to lead to the development of more synthetic alloys that can be used as alternatives to rare earth metals.
AND THIS IS THE WHILE POINT OF THE SCIENCE (SO LONG AS THE RARE EARTH THING IS IGNORED YET AGAIN) – IT IS A BREAKTHROUGH IN NANO-PROCESSING AND WAS NEVER INTENDED TO REPLACE NATURAL PALLADIUM. SCIENTISTS OFTEN PICK THE OPTIMAL COMBINATION OF VARIABLES TO TEST A NEW CONCEPT BEFORE THEY GET ON TO APPLYING THAT CONCEPT. IF YOU READ THE PAPER THE WORKERS STATE THAT THEIR HOPE IS THAT THE TECHNIQUE CAN BE USED TO MIX OTHER CURRENTLY UNMIXABLE METALS;
OR IN THEIR WORDS “Following on from the discovery of the Ag-Rh solid solution alloy, we envisage the development of new solid-solution alloys of immiscible Ag-Ni, Au-Rh, Cu-Ru, and others that exhibit phase-segregated structures, even in the high-temperature liquid phase.”
IN OTHER WORDS FORGET SILVER AND RHODIUM AND FORGET DELICATE MISTED SPRAYS, WHAT THESE GUYS ARE LOOKING FOR IS A QUENCHED SOLID THAT HAS THE SAME PROPERTIES BUT CAN WITHSTAND THE RIGOURS OF REAL-WORLD USE WHILST COMBINING RELATIVELY COMMON ELEMENTS. BASIC SCIENCE INVESTIGATING NEW IDEAS BUT WITH AN EYE TO THE FUTURE.
Joint research has already begun with car companies and Japanese electronics manufacturers, Prof Kitagawa said.
AT LAST SOMETHING THAT WE KNOW IS ALMOST CERTAINLY TRUE ! THE JAPANESE, THROUGH THEIR NATIONAL NATURAL RESOURCES STOCKPILER, JOGMEC, HAVE BEEN INVESTING IN ALL SORTS OF NATURAL RESOURCE PROCESSING TECHNOLOGY AND ALTERNATIVE MATERIAL DEVELOPMENT AS HAVE ALL THE MAJOR ECONOMIES.

If the journalist had actually read the original article (here translated from the original Japanese), clocked that some of the translation had some ambiguity, and then gone to the original scientific paper to address that ambiguity you wouldn’t have inane comment from all and sundry around the world aimed at a perfectly good piece of basic scientific research.
=======
A brief comment on the actual scientific paper which is visible on this link.
Its a really interesting piece of basic experimental science. Being able to spoof the properties of one metal by mixing adjacent metals together has all sorts of implications at a quantum level with regard to how molecules and atoms ‘decide’ which other molecules they can react with. In this case the fog of electrons appears to be fooling the incoming deuterium into acting as if something that isn’t there actually is. The really interesting bit is that only half the deuterium is acting that way and would love to know if this is a function of available storage sites or some other phenomenon.
