What are called nanosaws, nanocombs and nanowires can be grown (self-assembled) from cadmium selenium. A study of the temperature and pressure conditions were systematically varied and the impact on the growth was determined. The nanosaws and combs seem to be 2 microns wide. I think the nanowires are a few nanometers thick. While this is …
Researchers at UC Santa Barbara have potentially opened up a new avenue toward room temperature quantum information processing. By demonstrating the ability to image and control single isolated electron spins in diamond, they unexpectedly discovered a new channel for transferring information to other surrounding spins — an initial step towards spin-based information processing. A team …
Richard Smalley, a Rice University professor who discovered fullerenes, died Friday after a long bout with cancer
Quantum dots that produce white light could be the light bulb’s successor But chemists at Vanderbilt University discovered a way to make quantum dots spontaneously produce broad-spectrum white light. The report of their discovery, which happened by accident, appears in the communication “White-light Emission from Magic-Sized Cadmium Selenide Nanocrystals” published online October 18 by the …
This will help put us on the path to computational cell biology as an extension of computational chemistry. Computational chemistry is important to the development of molecular manufacturing. Yale researchers have reported a method to count the absolute number of individual protein molecules inside a living cell, and to measure accurately where they are located, …
The pages coming out of your color printer may contain hiddeninformation that could be used to track you down if you ever cross theU.S. government. Last year, an article in PC World magazine pointed out that printouts from many color laser printers contained yellow dots scattered acrossthe page, viewable only with a special kind of …
This advance is a modest advance along the path of brain scanning. Detailed brain scanning would be useful to reverse engineer the brain as an massive engineering approach to achieving human level artificial intelligence Ray Kurzweil has online articles on his thinking about this and he has his book The Singularity is Near which lays …
Advances with atomic force microscope accuracy advance us on the path towards molecular manufacturing. However, this does not achieve 0.5 angstrom accuracy as some Scanning Electron Microscopes have. It does help more labs get greater accuracy. Engineers at Purdue University have shown how researchers might better use tiny hollow fibers called “multi-walled carbon nanotubes” to …
This is not molecular manufacturing related but improved ability to detect proteins is part of enhanced protein handling that can be part of a protein based assembler. Northbrook, Illinois-based Nanosphere is preparing to launch a diagnostic system that uses nanoparticles to detect various proteins at a level of sensitivity never before seen. Scientists know that …
This work is advancing the DNA-Protein-enzyme pathway to molecular manufacturing. It is a process that is advancing toward scalable industrialized processes. Engineers build DNA ‘nanotowers’ with enzyme tools Duke engineers have added a new construction tool to their bio-nanofabrication toolbox. Using an enzyme called TdTase, engineers can vertically extend short DNA chains attached to nanometer-sized …
