Rise to prominence[edit]
Schön's field of research was condensed matter physics and
nanotechnology.[3] He received his Ph.D. from the University of Konstanz in
1997. In late 1997 he was hired by Bell Labs, located in New Jersey, United
States. There, he worked on electronics in which conventional semiconducting
elements (such as silicon) were replaced by crystalline organic materials.
Specific organic materials can conduct electrical currents, and in a so-
called field-effect transistor (a ... 阅读全帖

In addition to your thinking of the interaction between the support and
promoters, here are my two cents: (1) people usually focus more on the
interaction between the active Ni and Ba promoter, possibly some crystalline
phase such as Ni-Ox-Ba, (2) the charge transfer between the ceria and the
active sites. You are interested in the substitution of Ce by Ba in the
support, note that Ce is 4+ and Ba is 2+.

来自主题: Chemistry版 - 请做过SEM的缉拿来看一下
你看的那个文章好像只说超声可以分散powder, 没说能分辨非晶和晶体;超声大概是在溶液中产生局部的高温高压, 所以对分散或者溶解有促进, 甚至反应。
试试TEM, 可能分辨得出来;
非要SEM的话,不知道back-scatterd SEM 行不行, 等大牛来解答。

来自主题: Chemistry版 - 请做过SEM的缉拿来看一下
SEM不能分辨晶体与非晶,要区分这二者要用TEM打一打衍射看看。 但是如果只是想
看看颗粒大小之类的,超声是有作用的。把powder放在酒精或者丙酮里,超声几分钟
再滴在导电的substrate上,比直接把powder撒在carbon tape上,样品分散要好得多
有一些有明确外形的结晶体是很容易看出来的。

你说分不出来是因为你的 particle 都 aggregate 了,那把你的 powder 混在某种溶
剂里成悬浮液,然后 ultrasound, 就是帮助打散 aggregate。

用传统DCS测定polyurethane得不到Tg,后改用加热到180度然后再用液氮quench就得到了
这是因为提高了polymer的crystallinity的原因么?
在这个过程中最好加热到多少度再quench呢,quench会不会影响Tg
谢谢!

because the ions in amorphous phase do not suffer from the regular
