U jednoj knjizi sa pravoslavnom temom sam prčitala da smo zapravo  i dalje priključeni na drvo spoznaje dobra i zla, valjda preko tih IT. A opet u drugoj kako su pravoslavni u apokalipsi pobedili neznano kako i kada ih je posmatrač pitao kako su uspeli da pobede i sa čim su ratovali kad nisu imali oružja: rekli su  sa čim smo stigli

Da li je možda naša borba da zapravo na ovoj mreži svojim ponašanjem i govorom "prodobljavamo" internet, usporavamo informacije i unosimo radost u konzumente interneta? Sa čim god stignemo

WHY THIS MATTERS IN BRIEF

As our understanding of computing improves, it is clear that the post-silicon computing era will be anything but dull.

 

Over the past few years there have been a growing number of experts voicing concerns that Moore’s Law, and the age of silicon computing, is coming to an end as it gets more difficult and more expensive to grind out smaller and smaller transistor sizes. And that’s despite the fact that we already have 5nm, 1nm, 0.5nm and even virus sized and single atom sized transistors being developed in the labs.

 

However, despite all the doom mongers about the end of the “golden age of computing” coming to an end there are new staggeringly powerful computing technologies already emerging including quantum computers, that are 100 million times faster than today’s computers, neuromorphic computers that can pack all the power of today’s supercomputers into a package the size of a fingernail and revolutionise AI by learning for themselves, as well as more exotic biological, chemical, DNA computers that have been shown capable of packing the power of all of today’s global computing power into a test tube, and liquid computers. And all that’s for starters.

 

 

 

 

 

It’s the latter type of computing that’s the subject of another breakthrough that I’m going to discuss in this article, and be warned, it gets techy very fast. In 2017 I wrote about the development of the world’s first liquid transistor, and now a little over a year later another group in the US have created the world’s first “liquid computer chip.”

Invigorating the idea of computers based on fluids instead of silicon, researchers at the National Institute of Standards and Technology (NIST) have shown how “computational logic operations could be performed in a liquid medium by simulating the trapping of ions in graphene floating in a saline solution.” Outside of the computing realm the new discovery might also be useful in applications such as water filtration, energy storage and even sensor technology.

 

The idea of using a liquid medium for computing has been around for decades, and among their many advantages liquid computers would require very little material and space, and their liquid components could assume any shape, for example, within the human body where they could tag team with DNA computers to help turn the human body into disease fighting supercomputers. And yes, that’s a real thing – already.

NIST’s ion-based transistor and logic operations prototypes are simple in their design and, most crucially, showed for the first time that a special film immersed in liquid can act like a traditional solid silicon-based semiconductor like the hundreds of billions of computer chips used in all of today’s computing devices and gadgets.

As an added benefit the new material can even act like a transistor, the switch that carries out digital logic operations in a computer, and researchers demonstrated that the film could be switched on and off by adjusting the voltage levels in the fluid like those induced by salt concentrations in biological systems.

“Previous devices were much more elaborate and complex,” said NIST theorist Alex Smolyanitsky who led the ground breaking research. “What this ion-trapping approach achieves is conceptual simplicity. In addition the same exact device can act as both a transistor and a memory device – all you have to do is switch the input and output. This is a feature that comes directly from ion trapping.”

The NIST team used a graphene sheet 5.5 by 6.4nm in size that had small holes lined with oxygen atoms in it. These pores resemble something known as “crown ethers” – electrically neutral circular molecules that trap metal ions, while the graphene sheet itself was made up of carbon atoms arranged in hexagons, similar in shape to chicken wire, that conducts electricity and could be used to build electrical circuits. It was this hexagonal design that gave the team the breakthrough they needed and allowed them to create the pores they needed.

The graphene was suspended in water containing potassium chloride, a salt that splits into potassium and sodium ions, and the crown ether pores were designed to trap potassium ions, which have a positive charge and trapping a single potassium ion in each pore prevented the penetration of additional loose ions through the graphene sheet, furthermore that trapping and penetration activity could be tuned by applying different voltage levels across the membrane, which helped the team create logic operations with 0s and 1s – also known as binary operations which are the basis of all today’s computing platforms.

The input-output relationship between these operations also let the team create a NOT logic gate or operation,  where the input and output values are reversed. If 0 goes in, for example, then 1 comes out, and vice versa, and by using two graphene sheets rather than just one the team were also able to create an OR (XOR) logic operation.

 

Furthermore when the team applied just small variations in voltage across the membrane they were able to demonstrate a phenomenon known as “sensitive switching” which meant that it might even be possible to use the ion trapping crown pores to store information and perform sophisticated logic operations in what they called “nanofluidic” computing devices – or what I’ m going to simply call Liquid computers.

With all these advances in computing technology it is also becoming absolutely clear that the end of the silicon computing age is something to be celebrated not feared. And that’s before I tell you about how in 2020 Microsoft will start letting you store your information in DNA storage in the cloud, and how scientists last year managed to store and replay videos from living biological bacterial computers… In the future “computers” won’t just be everywhere, they’ll be powerful on a hitherto unimaginable scale.

NIST Researchers Simulate Simple Logic for Nanofluidic Computing

June 29, 2018

Invigorating the idea of computers based on fluids instead of silicon, researchers at the National Institute of Standards and Technology (NIST) have shown how computational logic operations could be performed in a liquid medium by simulating the trapping of ions (charged atoms) in graphene (a sheet of carbon atoms) floating in saline solution. The scheme might also be used in applications such as water filtration, energy storage or sensor technology.

The idea of using a liquid medium for computing has been around for decades, and various approaches have been proposed. Among its potential advantages, this approach would require very little material and its soft components could conform to custom shapes in, for example, the human body.

 

NIST’s ion-based transistor and logic operations are simpler in concept than earlier proposals. The new simulations show that a special film immersed in liquid can act like a solid silicon-based semiconductor. For example, the material can act like a transistor, the switch that carries out digital logic operations in a computer. The film can be switched on and off by tuning voltage levels like those induced by salt concentrations in biological systems. (See text box below.)

“Previous devices were much more elaborate and complex,” NIST theorist Alex Smolyanitsky said. “What this ion-trapping approach achieves is conceptual simplicity. In addition, the same exact device can act as both a transistor and a memory device—all you have to do is switch the input and output. This is a feature that comes directly from ion trapping.”

The NIST molecular dynamics simulations focused on a graphene sheet 5.5 by 6.4 nanometers (nm) in size and with one or more small holes lined with oxygen atoms. These pores resemble crown ethers—electrically neutral circular molecules known to trap metal ions. Graphene is a sheet of carbon atoms arranged in hexagons, similar in shape to chicken wire, that conducts electricity and might be used to build circuits. This hexagonal design would seem to lend itself to pores, and in fact, other researchers have recently created crown-like holes in graphene in the laboratory.

NIST researchers simulated computer logic operations in a saline solution with a graphene membrane (grey) containing oxygen-lined pores (red) that can trap potassium ions (purple) under certain electrical conditions.

 

In the NIST simulations, the graphene was suspended in water containing potassium chloride, a salt that splits into potassium and sodium ions. The crown ether pores were designed to trap potassium ions, which have a positive charge. Simulations show that trapping a single potassium ion in each pore prevents any penetration of additional loose ions through the graphene, and that trapping and penetration activity can be tuned by applying different voltage levels across the membrane, creating logic operations with 0s and 1s (see text box below).

Ions trapped in the pores not only block additional ion penetration but also create an electrical barrier around the membrane. Just 1 nm away from the membrane, this electric field boosts the barrier, or energy needed for an ion to pass through, by 30 millivolts (mV) above that of the membrane itself.

Applying voltages of less than 150 mV across the membrane turns “off” any penetration. Essentially, at low voltages, the membrane is blocked by the trapped ions, while the process of loose ions knocking out the trapped ions is likely suppressed by the electrical barrier. Membrane penetration is switched on at voltages of 300 mV or more. As the voltage increases, the probability of losing trapped ions grows and knockout events become more common, encouraged by the weakening electrical barrier. In this way, the membrane acts like a semiconductor in transporting potassium ions.

To make actual devices, crown ether pores would need to be fabricated reliably in physical samples of graphene or other materials that are just a few atoms thick and conduct electricity. Other materials may offer attractive structures and functions. For example, transition metal dichalcogenides (a type of semiconductor) might be used because they are amenable to a range of pore structures and abilities to repel water.

The research is funded by the Materials Genome Initiative.

Making A Logic Operation in Liquid

NIST simulations showed that ion trapping depends on the voltage across the porous graphene membrane, suggesting the possibility of performing simple ion-based logic operations. At sufficiently low salt concentration, the membrane’s highly conductive (on) regime coincides with low trapped ion occupancy, and vice versa. Direct electrical measurement of the membrane’s voltage, which might be used in an electrical circuit, is what’s known as a “read” operation.

If a low voltage, denoted 0, is applied across the membrane with appropriate salt concentration, the membrane is nearly nonconductive (off) and its pores are fully occupied by the trapped ions. Therefore, the charge in the graphene circuit, measured at the membrane, is relatively high, denoted as 1. Conversely, when high voltage (more than 300 mV), denoted 1, is applied, the membrane is highly conductive (on), fewer ions are trapped, and thus a low (0) state of energy in the membrane itself is measured.

The input-output relationship can be viewed as a NOT logic gate or operation, in which input and output values are reversed. If 0 goes in, then 1 comes out, and vice versa. With two graphene sheets an OR (XOR) logic operation would be possible. In this case, the output value, or the difference between the two membrane states, is 1 only when either of the two sheets is highly conductive. Stated another way, the output is 1 if the inputs are different but 0 if the two inputs are identical.

Even a small variation in applied voltage results in a relatively large change in potential membrane charge or current, suggesting that sensitive switching may be possible. Thus, voltage-tunable ion trapping in crown pores might be used to store information, and simple, yet sensitive ionic transistors might be used to perform sophisticated logic operations in nanofluidic computing devices.
