电子产品零售商百思买（Best Buy）最近决定停止销售模拟电视，这证实了一项新技术终于取代了旧技术。大约在同一时间，日本电子产品制造商索尼宣布将推出第一台使用有机发光二极管（OLED）技术的电视。它配备了一个11英寸的小屏幕和1,700美元的大价格标签。消费者非常清楚，高价格和有限的可用性是新技术的典型特征。当制造商改进和扩大生产时，价格下降，消费增长。碳纳米管市场也正在经历同样的动态。碳纳米管是由碳原子组成的六方晶格，被卷成微小的单层或多层管，具有独特的物理性质。15年前，它们还是昂贵的实验室珍品，现在正进入现实世界，生产商正在提高产能以满足需求。尽管纳米材料供应商表示，索尼的OLED电视不含纳米管、显示器和其他电子材料。
THE RECENT DECISION by electronics retailer Best Buy to stop selling analog televisions confirmed that a new technology had finally displaced an old one. Around the same time, Japanese electronics maker Sony announced that it would launch the first TV using organic light-emitting diode (OLED) technology. It comes with a small 11-inch screen and large $1,700 price tag. Consumers know all too well that high prices and limited availability are typical for new technologies. Prices decline and consumption grows when manufacturers improve and expand production. Markets for carbon nanotubes are experiencing these same dynamics. Carbon nanotubes, which are hexagonal lattices of carbon atoms rolled into minuscule singleor multiple-layer tubes, have unique physical properties. Expensive lab curiosities just 15 years ago, they are now moving into real-world uses, and producers are upping capacity to meet demand. Although nanomaterial providers say Sony’s OLED TVs don’t contain nanotubes, displays and other electroni...
