Neodymium and Dysprosium seperation. 160306

这是从 CEN  June 8,2015 引出, 原题"A New degree separation for Rare-earth metals".

同时在网上,以"Neodymium and dysprosium separation market"在google 上检索,

查到 Eric J,schelter 教授的文与照片.(在News中第二条)(JUNE 18,2015),综合如下:

1.Nd 和 Pr 通过 ligand (NO 为基础)分离,Nd溶介, Pr 结晶柝出.

2.主要从永磁体回收利用, Pr的价格较前涨了5倍.

3.试验将扩大至商业规模.

Start your engines. (catalysis) 160304

 As the Volkswagen scandal showed, building fuel-efficient, low-emitting vehicles is no easy task.


Volkswagen is still reeling from the U.S. Environmental Protection Agency's revelation that the


carmaker had altered diesel engines to beat emissions test , which caused immediate consumer


outrage . the agency reports that some diesel-powered vehicles made by Volkswagen and its


subsidiaries Audi and Porsche contained software that lowered emissions during test but not during


normal driving. On the road , some vehicles emitted up to 40 time as much NOx -a combination


of nitric oxide and nitrogen dioxide--as allow .

Biodiesel catalyst ranks to expand. (renewable) 160303

Growth in the biodiesel market is spurring two small companies to invest in U.S. production of
sodium methylate , a catalyst used to convert fats and oils into the renewable fuel. These Davids will be going up against two biodiesel catalyst Goliaths , the German chemical maker BASF and Evonik
industries.
U.S.biodiesel consumption has enjoy a meteoric rise from less than 100 million L in 2004 to almost
8 billion L in 2015.

Air products retreats from waste-to-energy. 160302

Air products & chemicals is ending a costly foray into the waste -to-energy business. Because of technical issues, it will not commission a pair of plasma gasification plants in tees Valley, England, and will instead write down as much as $ 1 billion in cost.
....The largest of these, in Wuhan , China, can process 150 metric tons of wood waste per day.
Combustion plants, however, are cheaper.  One that turns 1,000 tons of waste per day into 35MW
cost about $ 250 million to build.

Ineos begins shipping U.S. ethane to Europe. 160301

Ineos has shipped its first load of shale-gas-derived ethane from the port of Philadelphia to its


ethylene cracker in rafines,Norway. the Ineos Intrepid, the world's largest liquid natural gas ship,


set out earlier this month carry 27,500 m3 of ethane . the gas is cooled to -90 C for the 3,800KM


journey , which took about 10 days. "we know that shale gas economics revitalized U.S.


manufacturing, and for the first time, Europe can access this important energy and raw material


source too",says Ineos Chairman Jim Ratcliffe.

The talented 12. 15114

1. These daring young scientists are using chemistry to make the planet a better place.


 we like to pretend that the extraordinary young scientists profiled in the follow pages gather


regularly in a secret lair to plot how they'll fight global scourges such as climate change and human


disease.    From:  CEN     July 6, 2015 P.11-


 2.Considering a long life in science.


 Becoming a nonagenarian is an achievement worth celebrating. But being willing and able to


continue working at an age when most of a person's contemporaries a special devotion to one's


work. Some of the scientists run active research groups. Others stay engaged through collaborations


and writing. Doing science ,these chemists say, keep them active and sharp.


   From : CEN  JULY 20, 2015   P. 10-15


 3.Age and creativity.


  More than half of Nobel Laureates in chemistry from 1901to 1960 did their prizewinning work


by the time they were 40. Since 1961, prizewinners were likely to have done their acclaimed work


after their 40th birthday .  figure : year of Nobel prize 1901-2008 --age <30>51.
