奈米碳管Field Emission Display(FED) TVs將取代PDP與LCD?

Just as silicon is the wonder material for the computer age, carbon nanotubes will most likely be the materials responsible for the next evolutionary step in electronics and computing. Their extraordinary properties have identified them as having the potential to revolutionize many technologies. ...

In particular, it is widely believed that carbon nanotubes will take electronic devices to the next level. Many people expect the hugely popular LCD and plasma screens of today to be replaced by field emission flat screen displays (FED-TV). FED-TV's take all the best aspects of CRT's, LCD's and plasma TV's and roll them into a single package. While the technology exists, manufacturers are at present unable to compete with LCD's and plasma displays on a cost basis. However, carbon nanotubes have the ability to change all that.

目前由於cost的問題，其他的技術無法與LCD與PDP在成本上競爭。

In order to incorporate carbon nanotubes into devices like these field emission flat screen displays, an intimate knowledge of the properties of various forms of carbon nanotubes is invaluable. Researchers from University of Latvia, University College Cork, Trinity College Dublin, University of London and Mid Sweden University have just published work characterizing the conductive and field emission properties of single and multi walled carbon nanotubes.

In this research the conductive and field emission properties of individual single and multi-walled carbon nanotubes were assessed using an in-situ transmission electron microscope-scanning tunnelling microscope (TEM-STM) technique. The nanotubes were grown by chemical vapour and supercritical fluid deposition techniques.

Experimental field emission characteristics for all carbon nanotubes investigated fitted well to the Fowler-Nordheim equation when different work functions were applied. Differences in field emission and conductive properties are analysed and related to the structure of the carbon nanotubes. The method presented can be applied in order to make in situ selection of carbon nanotubes with desired properties for specific electronic applications.

The researchers found that conductivity and field emission properties were nanotube structure dependent. The structure of the outer layers and whether or not the nanotubes were filled with C60 molecules were key factors in determining the properties of the carbon nanotubes.

These findings make a significant contribution to the understanding of the structure/property relationships for carbon nanotubes, which in turn bring the next generation flat panel televisions and monitors a bit closer to our lounge rooms and offices.

投資理財第一步---先存錢

投資大師說：你不理財，財不理你。

記得在幾年前問一位朋友，有沒有在做投資理財投，他客氣的回答說：「青甲都不夠了，那還有得曬乾」，意思就是說，生活都成問題了，哪有閒錢作投資理財。但是這一點很重要，因為投資理財的重點在於「資」與「財」，也就是要先有錢，才能讓你來投資、理財。


有很多人可能手頭不是那麼充裕，或者收入與支出剛好打平，或者入不敷出，或者負債，可能都無法或不適合投資理財。因為投資理財基本上是用錢滾錢，沒有錢如何滾更多的錢，又如何應用72黃金法則呢?何謂72黃金法則，在善用72黃金法則，提前享受財富自由中有說明。即使是投資自己，也要花錢或花時間。

如果手頭沒有閒錢，又認為投資理財很重要的話，草木世界建議應該先存錢，至於如何才能夠存錢，簡單的說就是開源節流。這聽起來很老生常談，但卻很實際也很重要。開源就是讓自己的收入增加，兼差或者增加自己的價值都是一種很好的方法。節流就更重要了，因為收入大於支出，才有存錢的機會。台灣經營之神王永慶先生也說，營業額多十塊錢，盈餘未必多一塊錢，省一塊錢下來，才是真正的盈餘多一塊錢。

尤其是最近，各種原物料油電等都漲價，只有薪水不漲。收入有限的朋友若不實施節流的計畫，可能會讓自己變成月光族，那就無法存錢了。至於如何做到節流，我認為記帳是一個很重要的習慣，也是一種不錯的工具。那麼要如何記帳，草木世界 認為，要越簡單越好。因為太複雜，可能會讓你無法持續。

在此草木世界建議你可以用簡單的 excel 表，或者不喜歡用電腦的人，可以考慮用一本筆記本，把消費分成食、衣、住、行、育、樂、水、電、瓦斯、電話(含行動)、網路、紅白包、其他等項目。現在的消費大多有發票或收據，一週記一次，然後一個月作一次統整，樣一來你的消費行為就會被完全的顯示出來，分析哪一些項目，是不必要的花費。

幾個月之後，我們會發現有許多不需要買的，常常因為逛街會亂買。相信很多人都有這個經驗，到百貨公司或大賣場逛，原本不需要買的東西，因為大減價或者是促銷，就一口氣買了一堆，一段時間後，發現其實也沒有用。透過記帳，你可以漸漸的減少不需要的花費，將這些錢存起來，一段時間之後，也是一筆不小的錢，再用這些錢來投資好的標的與投資自己。

至於如何在食、衣、住、行、育、樂、水、電、瓦斯、電話(含行動)、網路省錢，請待續............^-^
