Computers and the Internet have become a big part of our daily lives but there are many people that are still weary about using the Internet. Contrary to popular belief, they are NOT old people who don’t even know how to use a cellphone. In fact, some of them are experienced internet users. So, the question is: Why are there are experienced people who try not to use the Internet in their work or daily tasks, such as homebanking?

The answer is rather simple: it is because they know how to use it and the potential dangers of the Internet that they don’t trust it and drive away from it. Trust has become an important issue in the Internet, especially since a lot of commercial transactions occur over the Internet and people need to be assured that their identity and money are safe while buying stuff over the internet or checking their email accounts. And that’s why most e-bussinesses try to make their sites hacker-safe through airtight security.

Nevertheless, there are still many security hazards on the Internet, such as phishing, CSRF, XSS, even forged security applications (such as fake anti spyware/malware application), and many other techniques aimed at breaking security on the Internet.

Because of that, people nowadays not easily trust something online (especially when it comes to online business or online transaction). With that in mind, Comodo has put forward their great vision towards trusted Internet and rhey are offering  many great tools that were developed to re-build trust. People don’t need to buy expensive security applications to be installed on their computer only to surf the Internet. I guess this idea of trusted Internet is possible to achieve, and I also glad if someday I don’t have to be worried when using Internet.

To prove their point and help build trust among internet users, Comodo has released several pieces of security-related software, just look into their website and you can download and use their free software on your computer and build security from the ground up. I’ve downloaded the Comodo BoClean and Comodo Firewall Pro, and so far, they’ve helped to get rid of some nasty spyware and shielded my notebook against several attacks coming from the Internet.

Many of the basic fabrication methods for single walled nanotube production have come from research out of Rice University. While most of Rice’s patents have previously focused on the single walled carbon nanotube type, a recent set of issued patents based on continuations (with priority going back to the 1990′s) have extended the patent coverage to “fullerene nanotubes” which may include double or multiwall nanotubes types that are being explored as field emitters and transparent electrodes in electronics and display applications.

US Patent 7419624 – Claims 1 and 3

1. A method of producing a composite material comprising fullerene nanotube material, wherein said fullerene nanotube material comprises fibers of fullerene nanotubes, and wherein said method comprises:
(a) preparing an assembly of a fibrous material;
(b) adding said fullerene nanotube material to said fibrous material; and
(c) adding a matrix material to said fullerene nanotube material and said fibrous material.

3. A composite material comprising fullerene nanotubes, a fibrous structural constituent and a matrix material, wherein the matrix material comprises a polymer and the fibrous structural constituent comprises carbon, and wherein the fullerene nanotubes comprise fullerene nanotube fibers.

(US Patent 7419651) Claims 1 and 13

1. A three-dimensional structure that self-assembles from derivatized fullerene nanotubes comprising: a plurality of multifunctional fullerene nanotubes assembled into said three-dimensional structure.

13. A structure formed by the process comprising:
(a) providing fullerene nanotubes derivatized with at least one functionally-specific agent;
(b) exposing the derivatized nanotubes to another moiety for which the functionally-specific agent has an attraction; and
(c) recovering assemblies formed by the derivatized nanotubes.

For applications in hydrogen storage and as molecular sieves short length (<1 micron) carbon nanotubes have been found to have advantages over longer tube lengths for the diffusion of gases. This patent discloses a method for producing such short length CNTs. Claim 1 reads:

1. A method for producing functionalised short carbon nanotubes with at least one open tip comprising mechanically treating long carbon nanotubes in a powder form, wherein a reactant gas able to chemically react with said long nanotubes is chosen and said long carbon nanotubes in a powder form are submitted to mechanical milling forces in the presence of said reactant gas so that short carbon nanotubes, comprising at least one specific chemical group, are obtained, and wherein said reactant gas is not air.
