不见得会因此而减少,还有可能因此而增加。
vitamin C是pro-oxidant就更搞笑了,vitamin C是anti-oxidant的原因不是因为橘子
里有其他东西,而是vitamin C本身是还原性的化学物质。还原性的化学物质是橘子的
一部分也好还是单独提炼合成出来的也好,还原性是不会变的。

GaAs vs. Si from wikipedia
Comparison with silicon
GaAs advantages
Some electronic properties of gallium arsenide are superior to those of
silicon. It has a higher saturated electron velocity and higher electron
mobility, allowing gallium arsenide transistors to function at frequencies
in excess of 250 GHz. Unlike silicon junctions, GaAs devices are relatively
insensitive to heat owing to their wider bandgap. Also, GaAs devices tend to
have less noise than silicon devices, especially at high fre... 阅读全帖

来自主题: Macromolecules版 - 关于氧化胺表面活性剂的求助!
大家好:
现在在做湍流减阻的试验用到了氧化胺表面活性剂。由于对氧化胺了解不深遇到了一些
问题。请大家帮忙共同探讨,解决一下。
1. 我们的得到的样品名称是:amine oxide, (C18), 30wt% . 我想确定一下是不是分
子式和octadecyldimethylamine oxide 一样呢?
2. 我们在110度做湍流试验的时候发现,注入500ppm 氧化胺水溶液, 湍流减阻的效果
很快就不见了(一般情况下只有棒状的表面活性剂在溶液中才有湍流的效果),我认为
是氧化胺在这个温度下结构发生了变化,查了一些资料发现,氧化胺在150-200度之间
才能发生消去反应。应该不是消去反应,各位认为是什么原因呢?
3. 表面活性剂像氧化胺这样的,如何判断它形成的micelle 的形状?可以直接查到吗

4 对于温度对表面活性剂水溶液影响的相图在哪里能找到?

Applications are invited for a postdoctoral position in Professor Guangwen
Zhou's group at the Department of Mechanical Engineering, State University
of New York (SUNY), Binghamton. The appointment is initially for a duration
of one year, annually renewable up to three years. The project addresses the
atomistic mechanism of metal oxidation from oxygen surface chemisorptions
to oxide nucleation and growth using variable-temperature ultrahigh vacuum (
UHV) scanning tunneling microscopy (STM) techn

我在running 版转帖了题为Extreme Endurance Exercise and heart attack的文章。
全篇文章都是认同跑步的好处,但是提醒过渡锻炼可能和心脏病有关联。
一些网友跳出来羞辱讽刺。我无所谓。文章总有喜欢和不喜欢的。
Rodimus对该帖极为不满,说running版不欢迎这类文章,封了很难看。同时说置顶文章
有类似讨论了。
我发帖反驳,问他是不是私人俱乐部,不允许公开发帖,同时要他拿出白底黑字的版规
看我违反了哪一条。我说我读了置顶文章,要么是空连接,要么内容不相同。我反问他
看我的文章没有。
Rodimus 根本拿不出任何版规,还说我的文章他不屑一看,居然发帖说我是受虐狂。
我发帖反驳说他动不动冒充全版不欢迎新人,还无根据威胁封人,是虐待狂。
Rodimus恼羞成怒,把我的帖子和后面更贴的对话全删了。
闹了半天是个不看贴就摆架子,威胁人,骂人,删帖的版主。混mit这么多年,还真遇
到极品版主了。
我要问站务,一个版主管理版面是靠版规还是靠威胁恐吓?繁荣版面是靠搞一言堂还是
容纳不同意见?
我恳请站务调查running版的奇怪风气,一个网友发一个很中... 阅读全帖

Sorry I don't have an article for how dopaminergic hyperactivity is
connected to glia. Just a random thought. I thought it might be an angle
worthwhile to look at?
Regarding the anti-oxidant and metabolic coupling capabilities, aren't these
two functions are coupled to each other? I mean along with metabolic
coupling, the glia will produce ROS and that will require them to be able to
handle the ROS, therefore anti-oxidant role. Could you be more specific?
Thanks.
