摘要:
Chalcogenide compounds with cation exchange capability and methods of using the compounds are described. Compounds of the general formula A2xMxSn3-xS6 are described wherein x is 0.1-0.95, A is Li+, Na+, K+ or Rb+ and M is Mn2+, Mg2+, Zn2+, Fe2+, Co2+ or Ni2+. Compounds of the general formula H2xMxSn3-xS6 are also described wherein x is 0.1-0.95 and M=Mn2+, Mg2+, Zn2+, Fe2+, Co2+ or Ni2+. The compounds can be layered compounds. The compounds are capable of intercalation of Cs+, Sr2+, Hg2+, Pb2+, Cd2+, and/or Ag+ ions. A process involving contacting the compounds with a solution comprising one or more ions including Cs+, Sr2+, Hg2+, Pb2+, Cd2+, and/or Ag+ is also provided. The one or more ions can be removed from the solution by the compounds. A process comprising contacting compounds of the general formula A2xMxSn3-xS6 with a solution containing UO22+, Th4+ or Pu4+ ions is also described.

摘要:
Methods, systems, and apparatus for quantum phase estimation. In one aspect, an apparatus includes a quantum circuit comprising: a first quantum register comprising at least one ancilla qubit, a second quantum register comprising one or more qubits, wherein the second quantum register is prepared in a quantum state that is not an eigenstate of a unitary operator operating on the first and second quantum register; and a phase learning system, configured to learn phases of the eigenvalues of the unitary operator.
摘要:
An impact-type rotary fining, homogenizing and emulsifying device is constituted by a casing body disposed on a base, a feed port and a discharge port disposed in the casing body, and a power shaft disposed inside of the casing body. The power shaft is equipped with rotary impellers in such a manner that the rotary impellers are disposed on the power shaft and include a first rotary impeller rotated in a positive direction and a second rotary impeller rotated in negative direction. A power shaft portion is located in the feed port and is equipped with a feed impeller. A valuable advantage is obtained in that its new and distinct structure and innovative design enable the device to heighten the impact velocity applied to treated materials many fold, without raising the rotating speed of the impellers. Functions of fining, homogenizing and emulsifying are improved, while effectively enhancing the overall performance of the apparatus, within the motor's allowable rotational speed.
