Low valent metal compounds are common reducing agents. Samarium, which is most stable in the third oxidation state (also like all other lanthanides), is used in the second oxidation state as an one-electron reducing agent. Samarium(II) compounds can be produced in situ by a reaction of samarium(III) salts with metallic samarium. Also the derivatization from the commercially available SmI2 to more reactive compounds is possible.. The fact that samarium compounds are very mild reducing agents were demonstrated impressively by the mentioned examples. Therefore, the Pinacol rearrangement can be accomplished in water.. Besides, in some reactions the affinity from samarium to oxygen is evident. This can be used for Barbier or Grignard-type reactions to cause the reaction of alkyl halides with ketones and aldehydes.. ...

Single Element Lumina™ Hollow Cathode Lamp (HCL) for the detection of elemental Samarium (Sm). Please note that this element requires the use of a nitrous oxide-acetylene flame.. Every genuine PerkinElmer lamp is designed for use with and tested on our spectrometers to assure compatibility and the highest performance. We offer a wide range of single-element and multi-element HCLs, which are ideal for determining most elements by atomic absorption spectroscopy. To prolong the life of a Lumina™ Hollow Cathode Lamp (HCL), we produce lamps with larger internal volume so that a greater supply of fill gas at optimum pressure is available. The larger the lamp, the greater the inert gas volume - and the longer the lamp lifetime.. Note: Lumina™ Hollow Cathode Lamps may also be used with all earlier AA spectrometers that do not have automatic code reading capability by using an appropriate adapter cable. ...

Yet another reason why the above claims are taken with a huge grain of salt is that the so-called Oklo bounds imply a slower variation of $\alpha$. 2 billion years ago, when the Earth was young and beautiful, the uranium-235 isotope was five times more abundant than today. Thanks to that fact and some other lucky coincidences, near the river Oklo in todays Gabon nature could create a fully organic nuclear reactor which operated for 100 million years. The uranium fission produced many rare isotopes, and the particular ratio of Samarium-149 to Samarium-147 can be used to constrain variation of the fundamental constants. The point is that the cross-section for the neutron capture on Samarium 149 is accidentally enhanced by a presence of resonance just 0.1 eV above the threshold. From the fact that the position of this resonance could not migrate by more than 0.1 eV one can set the bound $\Delta \alpha/\alpha \sim 10^{-7}$ (assuming that only the electromagnetic constant is varied) corresponding to ...

You might want to develop a prototypical envelope for the generator, perhaps from a pointcloud representation, and then calculate the correct duct conformation and turbine wheel for the size and make that part of the casting coring. The generator is probably best approximated with permanent-magnet excitation (using commercial samarium or NIB magnets) and simple coil structure, again inside the scale generator housing. You would then model the visible portion of the structure and shaft at the interstage, behind the access door, to scale (perhaps as components that press over the actual shaft prior to final balancing ...

Controlled pore structure catalysts are disclosed that are active for catalyzing the partial oxidation of methane to CO and H2 and, advantageously, are capable of initiating the reaction without the need for an additional ignition source. A preferred catalyst comprises rhodium and samarium supported on an alumina or modified alumina support having certain surface area, pore volume, pore size and metal dispersion characteristics that permit light-off of the reaction at temperatures below 500 C. and with little or no use of an ignition agent. A method of partially oxidizing a light hydrocarbon to form synthesis gas, and a method of enhancing low-temperature light-off of the process are also described.
