标 题: silanization of coverslip
发信站: BBS 未名空间站 (Fri Sep 3 11:45:56 2010, 美东)
I saw some protocols using waters solution of silane to do the silanization
and some protocol using acetone or heptane solution. I am wondering which
one is better.
Thanks a lot

发帖数: 217 | 5 家在中西部，最近下大雨发现地下室两个没有装修的closet里面有水从水泥地基最上面
滴进来。请来的contractor说是雨水渗进砖墙导致的。正常情况下外面的砖墙在水泥地
基上面都有一层防水塑料膜，并且每隔1-2米左右就有一个小孔让渗进去或者从屋顶漏
进去的水流出来。但是房子正门那里砌了几个台阶，把应该往外面流的水挡住了，于是
渗进砖墙的雨水就往地下室流了（地下室的那两个closet正好在正门的两边）。他建议
用silane/siloxane把外墙处理一下，这样雨水就不会渗进来了。几个问题想请教一下
大家：
1：他说的原因大家同意吗？
2：地下室是装修的，是不是有砖墙的那一面任何地方都有可能有水进来？需不需要打
开dry wall看一下？
3：Contractor要价$1000左右，但是我们家房子只有正面是砖墙（或者贴砖），是不是
太贵了？
谢谢大家！ |

发帖数: 848 | 18 What is PEX?
PEX is cross-linked polyethylene. Through one of several processes, links
between polyethylene molecules are formed to create bridges (thus the term "
cross-linked). This resulting material is more durable under temperature
extremes, chemical attack, and better resists creep deformation, making PEX
an excellent material for hot water and other applications.
How long has PEX been used?
PEX was developed in the 1960s. PEX tubing has been in use in many European
countries for plumbing,... 阅读全帖 |

pirana清洁那步还是一样的，然后用Trichloro(1H,1H,2H,2H-perfluorooctyl)silane
。这东西挥发，所以不用拉膜。只要弄几个毫升放个表面皿里，然后和silicon wafer
放在一个密闭容器内，过一夜，你的wafer表面就会有一层含氟layer，和PTFE一样不粘
。对了，密闭容器里不要太干，需要痕量的水催化反应
