Molecular electronics, where charges move through tiny, sole molecules, could be the future of computing and, in particular, storage, some scientists say.\nResearchers at Arizona State University (ASU) point out that a molecule-level computing technique, if its development succeeds, would slam Gordon Moore\u2019s 1965 prophesy \u2014 Moore's Law \u2014 that the number of transistors on a chip will double every year, and thus allow electronics to get proportionally smaller. In this case, hardware, including transistors, will conceivably fit on individual molecules, reducing chip sizes much more significantly than Moore ever envisaged.\n\n\u201cThe intersection of physical and chemical properties occurring at the molecular scale\u201d is now being explored, and shows promise, an ASU article\u00a0says. The researchers think Moore\u2019s miniaturization projections will be blown out of the water.\nUltra-miniaturization, using chemistry and its molecules and atoms, has been on the scientific community radar for a while. However, it\u2019s been rocky\u2014temperature has been a problem, among other things.\nOne big issue, which may be about to be solved, is related to controlling flowing electrons. The flowing current, acting like a wave, gets interfered with\u2014a bit like a water wave. The trouble is called quantum interference and is an area in which the researchers claim to be making progress.\nResearchers want to get a handle on \u201cnot only measuring quantum phenomena in single molecules, but also controlling them,\u201d says Nongjian "NJ" Tao, director of the ASU's Biodesign Center for Bioelectronics and Biosensors, in the article.\nHe says that by figuring the charge-transport properties better, they\u2019ll be able to develop the new, ultra-tiny electronics devices. If successful, data storage equipment and the general processing of information could end up operating through high-speed, high-power molecular switches. Transistors and rectifiers could also become molecular scale. Miniaturization-limiting silicon could be replaced.\n\u201cA single organic molecule suspended between a pair of electrodes as a current is passed through the tiny structure\u201d is the foundation for the experiments, the school explains. A system called electrochemical gating, where conductance is controlled is then used. It manages the interference and is related to how \u201cwaves in water can combine to form a larger wave or cancel one another out, depending on their phase.\u201d Through this science, the researchers say they\u2019ve been able to, for the first time ever, fine-tune conductance in a molecule. That's a big step.\u00a0\nOther chemistry-related data storage research\nI\u2019ve written before about chemistry \u201csuperseding traditional engineering\u201d in shrinking data storage. Last year, unrelated to this ASU and others\u2019 quantum interference project, Brown University said it was working on ways to store terabytes of data chemically in a flask of liquid.\n\u201cSynthetic molecule storage in liquids could one day replace hard drives,\u201d I wrote. In a proof of concept, the Brown team loaded an 81-pixel image onto 25 separate molecules using a chemical reaction. It works similarly to how pharmaceuticals get components onto one molecule.\nResearchers at the University of Basel in Switzerland are also attempting to reduce data-storage size through chemistry. That team explained in a media release late last year that it plans to use a technique similar to what\u2019s used to record to CD, where metal is melted within plastic and then allowed to reform, thus encoding data. But they want to attempt it on an ultra-miniature atomic or molecular level. It's just succeeded controlling molecules in a self-organizing network.\nAll of the research is impressive, and like the ASU article says, \u201cIt\u2019s unlikely Moore could have foreseen the extent of the electronics revolution currently underway."
