These two U boats are also thought to have carried Uranium oxide requested for Japan's atomic bomb project by General Toranouke Kawashima in July 1943.

Nichols arranged with the State Department for export controls to be placed on uranium oxide and negotiated for the purchase of of uranium ore from the Belgian Congo that was being stored in a warehouse on Staten Island and the remaining stocks of mined ore stored in the Congo.

Klaproth assumed the yellow substance was the oxide of a yet undiscovered element and heated it with charcoal to obtain a black powder, which he thought was the newly discovered metal itself (in fact, that powder was an oxide of uranium).

Binary compounds Iron reacts with oxygen in the air to form various oxide and hydroxide compounds the most common are iron(II,III) oxide (Fe3O4), and iron(III) oxide (Fe2O3).

Grades Slightly enriched uranium (SEU) Slightly enriched uranium (SEU) has a 235U concentration of 0.9 to 2 .

Yellow iron oxide (E172)

Isotope separation Natural uranium consists of 99.3 uranium 238 and 0.7 uranium 235, but only the latter is fissile.

By July 1942, Mallinckrodt was producing a ton of highly pure oxide a day, but turning this into uranium metal initially proved more difficult for contractors Westinghouse and Metal Hydrides.

It's great. Lots of NO is released.

Other compounds include cerium(III) carbonate (Ce2(CO3)3), cerium(III) fluoride (CeF3), cerium(III) oxide (Ce2O3), as well as cerium(IV) sulfate (ceric sulfate, Ce(SO4)2) and cerium(III) triflate (Ce(OSO2CF3)3).

In 1941 he began working with uranium hexafluoride, the only known gaseous compound of uranium, and was able to separate uranium 235.

This was then heated to form uranium trioxide, which was reduced to highly pure uranium dioxide.

The high uranium content makes carnotite an important uranium ore and also radioactive.

The NDRC Committee on Uranium became the S 1 Uranium Committee of the OSRD the word uranium was soon dropped for security reasons.

Half of the world's solder consumption is in electronics (i.e., circuit boards).

These rockets use experimental motors like nitrous oxide.

Thus, radium is found in tiny quantities in the uranium ore uraninite and various other uranium minerals, and in even tinier quantities in thorium minerals.

The manganese dioxide is reduced to the manganese oxide hydroxide MnO(OH) during discharging, preventing the formation of hydrogen at the anode of the battery.

Since it is chemically identical to the most common isotope, uranium 238, and has almost the same mass, it proved difficult to separate.

(235U is only 1.26 lighter than 238U.

Actinium 227 occurs in uranium ore.

A relatively simple gun type fission weapon was made using uranium 235, an isotope that makes up only 0.7 percent of natural uranium.

The brown substance was the oxide of the element holmium and was named holmia by Cleve, and the green substance was the oxide of an unknown element.

Chemoautotrophic arsenite oxidizers (CAO) and heterotrophic arsenite oxidizers (HAO) convert As(III) into As(V).

And then we get to uranium.

For example, ν 2.5 for uranium 235.

It seemed we couldn't turn off the production of nitric oxide in the skin of humans.

Baddeleyite is a rare zirconium oxide mineral (ZrO2 or zirconia), occurring in a variety of monoclinic prismatic crystal forms.

Uranium is used in the production of nuclear power.

Uranium is a constituent of most rocks, dirt, and of the oceans.

Aggregate U 235 production About of uranium enriched to 89 uranium 235 was delivered to Los Alamos by July 1945.

The most common ionic forms are (brown red), (green), (unstable), and (yellow), for U(III), U(IV), U(V), and U(VI), respectively.

Nitrous oxide reacts with ozone in the stratosphere.

It is an oxide mineral belonging to the spinel group.

In the laboratory, aluminium oxide (or porous pot) must be heated.

Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula 23.

Pitchblende, after removal of the radioactive elements uranium and thorium, was more radioactive than the uranium and thorium combined.

Work was proceeding on three different techniques for isotope separation to separate uranium 235 from uranium 238.

At the time, there was a limited source of pure uranium.

The half life of uranium 238 is about 4.47 billion years and that of uranium 235 is 704 million years, making them useful in dating the age of the Earth.

Bromides and iodides of uranium are formed by direct reaction of, respectively, bromine and iodine with uranium or by adding to those element's acids.

This may indicate possible contamination by small amounts of bacteria, underground sources of radiation causing the 14N(n,p) 14C reaction, direct uranium decay (although reported measured ratios of 14C U in uranium bearing ores would imply roughly 1 uranium atom for every two carbon atoms in order to cause the 14C 12C ratio, measured to be on the order of 10 15), or other unknown secondary sources of carbon 14 production.

Via ethylbenzenehydroperoxide Commercially styrene is also co produced with propylene oxide in a process known as POSM (Lyondell Chemical Company) or SM PO (Shell) for styrene monomer propylene oxide.

And these are more stable, and your skin has got really large stores of NO.

Martin Heinrich Klaproth independently discovered the same oxide and called it ochroia .
