Editing Palladium (section)

===Photography===
In the [[platinotype]] printing process, photographers make fine-art black-and-white prints using platinum or palladium salts. Often used with platinum, palladium provides an alternative to silver.<ref>{{cite journal |first=Mike |last=Ware |title=Book Review of : Photography in Platinum and Palladium |journal=Platinum Metals Review |volume=49 |issue=4 |pages=190–195 |date=2005 |doi=10.1595/147106705X70291 |doi-access=free}}</ref> But palladium is more inert than the silver used in [[silver bromide]] prints, so such photographs are better archived than conventional prints and convey details more clearly.<ref>{{Cite web |last=McCabe |first=Constance |title=Noble Metals for the Early Modern Era:  Platinum, Silver- Platinum, and Palladium Prints |url=https://www.moma.org/interactives/objectphoto/assets/essays/McCabe.pdf |website=[[MoMA]]}}</ref><ref>{{Cite web |last=Ware |first=Mike |title=The Technical History and Chemistry of Platinum and Palladium Printing |url=https://www.culturalheritage.org/docs/default-source/publications/books/platinum-and-palladium-photographs/46-83_ware_technicalhistorychemistry.pdf |website=Culturalheritage.org}}</ref>

===Art===
Palladium leaf is one of several alternatives to [[silver]] leaf used in [[manuscript illumination]]. The use of silver leaf is problematic because it tarnishes quickly, dulling the appearance and requiring constant cleaning. Palladium is a suitable substitute owing to its resistance to tarnishing. [[Aluminium]] leaf is another inexpensive alternative, but aluminium is much more difficult to work than gold or silver and results in less-than-optimal results when employing traditional metal leafing techniques, so palladium leaf is considered the best substitute despite its considerable cost. Platinum leaf may be used to the same effect as silver leaf with similar working properties, but it is not as commercially available on demand in leaf form.<ref>{{cite book |first=Margaret |last=Morgan |title=The Bible of Illuminated Letters |publisher=Barron's Educational Series |isbn=978-0-7641-5820-9 |page=50 |year=2007}}</ref><ref>{{cite web |publisher=[[Theodore Gray]] |title=Palladium Leaf |url=http://www.theodoregray.com/PeriodicTable/Samples/046.6/index.s12.html}}</ref>

==Research==
===Cold fusion===
{{Main|Cold fusion}}
Palladium plays an important role in the ongoing research into cold-fusion energy.

===Super tough metallic glass===
Research is being done to develop metallic glass as a microalloy featuring palladium, a metal with a high "bulk-to-shear" stiffness ratio that counteracts the intrinsic brittleness of glassy materials. The initial samples of the new metallic glass were microalloys of palladium with [[phosphorous]], [[silicon]] and [[germanium]] that yielded glass rods approximately one millimeter in diameter. Adding [[silver]] to the mix enabled the Cal Tech researchers to expand the thickness of the glass rods to six millimeters.<ref>{{cite news |url=http://www.scientificcomputing.com/news/2011/01/new-glass-stronger-any-known-material |title=New Glass Stronger than Any Known Material |date=2011-01-11}}</ref>

===Alternatives===
[[Pseudo palladium]] (RhAg) is a binary alloy consisting of equal parts of rhodium (atomic number 45) and silver (atomic number 47). This alloy exhibits properties of palladium (atomic number 46).<ref>{{cite journal |last1=Kusada |first1=Kohei |last2=Yamauchi |first2=Miho |last3=Kobayashi |first3=Hirokazu |last4=Kitagawa |first4=Hiroshi |last5=Kubota |first5=Yoshiki |title=Hydrogen-Storage Properties of Solid-Solution Alloys of Immiscible Neighboring Elements with Pd |journal=Journal of the American Chemical Society |volume=132 |issue=45 |pages=15896–8 |year=2010 |pmid=20979361 |doi=10.1021/ja107362z}}</ref>
