Google Buys Blogger: "Internet search company Google  Inc. has agreed to acquire Pyra Labs, the handful of Web developers who helped jump-start the personal publishing phenomenon known as blogging, Pyra's founder said on Sunday."  4:26:09 PM  permalink  

Collaboration war story: "On December 9-10, 2002, over 120 technology industry leaders gathered at the Supernova conference in Palo Alto, CA to discuss the impacts of decentralizing technologies such as Web services, WiFi, Weblogs, and broadband media. .. A few highlights:..

* Cap Gemini Ernst & Young CTO John Parkinson's bold proclamation that after spending a billion dollars on collaboration software, he hadn't seen anything that worked.  4:14:47 PM  permalink  

Lifting the veil on VC returns: "the University of Michigan released the performance results of the most respected, and secretive, of Sand Hill Road's venture capital firms -- warts and all (Click here to read the document)."  4:09:49 PM  permalink  

Introduction to nanohorns: "The types of nanotubes used for the experimental fuel cell are named nanohorns due to their irregular horn-like shape, and were discovered in the late 1990s. Although nanohorns have the same graphitic carbon atom structure as normal nanotubes, their distinguishing characteristic is a preference for grouping together to create an aggregate (that is, a secondary particle) of about 100nm. When used as an electrode for a fuel cell, not only is the surface area of the aggregate extremely large, but it is also easy for the fuel to permeate to the inside. Additionally, high purity nanohorns are easy to create (in comparison with other forms of nanotube) and are therefore predicted to be a low-cost raw material."  In late 2001, JST and NEC "discovered that single layer nanohorn can storage 160 times methane in volume. By heat-treating single layer nanohorn at 400 °C under oxidizing atmosphere, nanohorn has nano-size fine pores and increases its surface area. In case of ordinary nanohorn, gas can flow through only conical opening, but in case of nanohorn having fine pores, gas can flow through also fine pores and methane gas is changed into super critical liquid by interference of methane molecule and nanohorn wall including fine pores even at room temperature. It is understood that these mechanism make nanohorn possible to storage methane in high density."  NEC also reported efficient deposition of platinum on nanohorns for use in fuel cells.  11:56:55 AM  permalink
