m*******u 发帖数: 41 | 8 cam --和cad不分家的,知道cad也得会
pdm-有些深奥,小公司这方面不太感冒
lean manufacturing 很热门的词,这年头啥都要lean
以上是我的感受,不对的地方请改正,欢迎牛人来补充 |

c*m 发帖数: 40 | 9 美国机械工程硕士毕业,在国内有8,9年的工作经验,主要是做3D modeling, 2D
drawing, 机械设计,产品开发等。接触过的产品有PDA(personal digital assistant
),circuit breaker, busway, diesel engine等。熟练使用ProE, UG NX, AutoCAD,
Ideas等,还有PDM系统象TeamCenter。也自学过美国比较流行的Creo,SolidWorks等,
感觉命令都差不多,稍微一练也都能上手。
现在在西雅图地区,因为家庭原因无法去其它地方工作。想在本地找一个机械方面的工
作,level不限,工资不限,性质不限。
已经有EAD,所以不需要visa sponsorship。没有绿卡或公民身份。
恳请内推。请回复或站内联系。 |

h***s 发帖数: 111 | 11 I would not think there will be any problem, 100 nm should be pretty easy to
achieve. Do you have any hard template, e.g. Si or SiN, instead of PDMS?
BTW, what's the aspect ratio? |
|
j******n 发帖数: 25 | 12 这样行不行
用pdms做个片,上边打两个洞,放置时保证洞在槽上方(一头一尾)
往一侧洞里边滴CNT的suspension,另一侧用个小泵或其他方法吸
印象中很多人用这种fluidic的方法align CNT |
|
s******x 发帖数: 15232 | 13 那为什么不直接拿一块已经硬化的pdms压在槽上方,这样槽就只有两头从侧面可以进出
;然后一侧往里边滴CNT的suspension,另一侧用个小泵或其他方法吸 |
|
s******x 发帖数: 15232 | 14 另外我猜想,是不是可以先deposit或者grow alligned nanotube everywhere on the
wafer,然后用pmma或者已经硬化的pdms stamp来把表面上的tube粘掉,槽里的比较容
易幸存? |

c**s 发帖数: 80 | 15 看了原文,有几个地方不懂。比如Figure 5,为了测出internal quantum efficiency(
IQE),为什么作者比较wire-array electrode (blue)和wires after being polymer-
embedded and peeled from the growth substrate (black) 两种样品的external
quantum efficiency(EQE)?作者不是说主要的parasitic adsorption是因为surface
states, impurities or residual VLS catalyst metal deposits. 镶嵌在PDMS里和从
衬底上剥离,如何就去掉了surface states和impurities的效应呢?
那位photovoltaics/solar cell的大拿给外行讲讲? |
|
D***s 发帖数: 120 | 16 他们只测了一个EQE,就是wire array photoelectrode的,这个是除去重掺杂硅基底并
且嵌在PDMS里的。然后normalize这个EQE到纳米线阵列的吸收谱,得到IQE。测吸收谱
用的样品是含有重掺杂硅基底的,所以在后面的补充材料里他们给出了单独这个硅基底
的EQE,claim这个影响非常小,可以忽略不计。 |

R*Q 发帖数: 179 | 17 上次跟我们的pharmacy district manager(PDM)谈过,说现在retail基本都不提供
intern position给international pharmacist。他说只有加州可能还有机会,但也不
清楚。
Pharmacy TECH是极其廉价的劳力而且干得好还需要多种技术,好的TECH可以完成80-90
%药师的活。但pay得比很多超市的cashier工资还低。Tech是很非常容易找的,网上可
以申请,也可以到药店找药店manager当面谈.没有回应的原因是,药店经理上班时剧忙
/做事没条理/经常抓瞎,轮到休息又不可能为公司招人(没人pay 他们,也不允许做)。
如果你们州tech不能算intern小时,就不要做。累得要死不说,被人呼来唤去的滋味非
常恶心。那点时间还不如全心脱产过TOEFL。一旦开始做TECH,就会被不停榨取,根本
不再有暇系统搞托福。
TECH非常不被尊重,因为只要求高中学历。比如上头来检查,TECH就如牛马,他们跟没
看见一样,但事实上药店的盈利80%来自对TECH的剥削,没有TECH,药店稍微忙一点就
是个MESS。

2) 迅速联系病人,纠正错误
3)如果问题大,必须call corporate PDM,让他们可以提供帮助。万一病人直接联系公
司,他们也可以有处理预案。
不知说得对不对 |

m**s 发帖数: 520 | 19 执照能拿就拿了再说,多一条谋生也不是坏事
FDA/NIH好像一直有pharmacist opening,工资比retail少不少,没多少人愿意去。但政
府衙门,据说无比轻松,也不必如在retail工作那样,成天担心犯错误,哪天惹翻刁蛮
顾客被PDM解雇。退休金更是没法比。这就是我的人生目标。回想当年新读PHD的豪情万
丈,现在却想方设法为五斗米折腰,自己也骂自己,萎缩! |

m**s 发帖数: 520 | 20 难道饿死满大街开药店的了,呵呵!
估计还是大鱼吃小鱼,最后剩几家大的连锁,希望能谋个PDM职位爽爽 |

h*********r 发帖数: 650 | 26 From PdI to a place called Confluencia(3000m) takes about 4-5h, from
Confluencia to PdM about 8-10h. For acclimatization and to avoid a
real long walk it is recommended to spend a night at Confluencia.
Confluencia has a few tents, where you can get Coke and similar things.
It may be possible to sleep in one of those tents, but I would not rely
on it. From Confluencia you have to carry water, unless you have a filter.
Shortly after leaving the road to Chile, you'll find a checkpost who wants

Most people use white gas (Spanish: bencina blanca) stoves. Above Plaza

fuel per person (anticipating you may have to await the end of a storm
