Whose also Later It Is Possible can become Spider-man : Small channel carbon nano in the place of artificial gecho hair


Deddy Sinaga

Leaved at the post just time of spider man story in comic becomes reality. Professor Nicola Pugno, engineer and physicist from Politeknik Turin in Italian, has designed a clothes enabling its(the consumer creeping at vertical wall or walk at ceiling.

Later, said Profesor Pugno, whose also can become Spider-Man, figure superhero in comic.

But, the clothes also multifungsi. " Can be used starts exploration of space until defence importance, even can also is design clothes for skyscraper building glass cleaner officer," says Pugno in its(the presentation in physicist journal Condensed Matter edition Thursday last week.

The clothes consumer can creep at equiamplitude surface cause wall of the clothes is viscid. Its(the inspiration is gecho, reptil capable to patch at inversed or vertical wall without need to clutch anything.

The scientists finds that gecho viscid at wall creeped over by it because its(the legs having remarkable smooth hair many. The hair called as setae. The numbers around 500 thousand sheets in every gecho leg. But, its(the scale is very small, each around 10 microns ( 1 micron = 10-6 meter).

At the end of every setae there are 1001000 smaller hairs again, what named spatula. Its(the scale around 100 nanometers ( 1 nanometer = 10-9 meter).

Setae and this spatula yields sticky energy?power a gecho. The scientists calculates, every piece of spatula has sticky energy?power 10 nanonewton. So imagines its(the strength if(when at every leg there is millions of spatula.

Viscid energy?power Spatula happened as result of existence of energy?power intermolekuler ( tarikmenarik intermolecular) leg with equiamplitude surface stepped on. This energy?power called as also interaction Van der Waals.

Energy?power intermolekuler happened when its(the rise electron between spatulas and equiamplitude surface stepped on. Accumulation of billion trade-offs energy setae makes gecho and labalaba can creep at wall and glass equiamplitude surface.

Its(the leg also able to be stepped easily, even like gluing at equiamplitude surface stepped on by it. This happened intermolekuler energy?power cause is very weakening.

The scientists proves accumulation of intermolekuler energy?power makes gecho ready to account weight hundreds of times his own body weight. For example, gecho which wt. 70 grams simply ready to arrest;detain payload to 133 kilograms.

This nature of inspiration a number of experts, until Pugno, checks the application of his(its at man. They thought, if leg and gecho hair can be imitated, non unlikely of man also can creep at vertical wall like Spider-Man.

Artificial gecho hair ( Velcro) also is created. But Pugno finds, hair made in that do not as sticky its(the original.

Don't know why, increasingly artificial gecho hair area wide, exactly its(the viscid decreases. a gauntlet fulfilled by artificial gecho hair not as sticky dinky gecho leg. " In consequence, required gauntlet and shoe with sticky energy?power larger ones," said Pugno.

Pugno also finds new formula, namely carbon nanotubes ( CNTS) in the place of Velcro. This carbon is in the form of teeny platen, width less than 1 nanometer ( 50 thousand smaller times than man hairs).

Sewer Structures CNTS haves the power of the same with levator skapula. Besides, this carbon one one another with interaction Van der Waals. This interaction makes it becomes one of material is strong, exceeds carbon steel. CNTS also is spelled out members electrical intrinsic semiconductor.

This mouldable carbon like hook and fairish tresss of nano which will function like microscopic fairish Velcro. Interaction of Van der Waals and hair small channel viscid energy?power ( capillarity) at this carbon makes it is stickier than artificial gecho hairs, at least on paper.

Pugno and its(the team is then clothes material design, gauntlet, and general shoe of gecho ala. They also cable design or cord made from 4 million piece of fiber nanotube.

Every sheet jointed at ingot dissociating every fiber as far as 5 micron. Fiber nanotube makes cord naturally would be sticky at substance anything.

the Clothes and cord, said Pugno, also must have other excellence, namely keep impurity will not making its(the viscid energy?power decreases. The clothes must ready to clean their/his self.

The clothes also super-hydrophobic water resistance alias must lamellar of kelor. Prilled of water which do not diffuse is useful at the same time as pengusir impurity particle.

Pugno tells, this temporary, clothes design and cord still on paper. Realizes that thing of course do not easy to tell him. " But, sees that gecho naturally ready to do it, that thing is not impossible," said him(her. Pugno is continuing, " However, step of we closer, ere long we can witness man to climb Empire State Building without anything besides sticky shoe and gauntlet."

Its(the problem, has made ready ordinary man become like Peter Parkers the spider man ? The reason is, there are still humanitarian hindrance of which must be overcome if wish to creep at wall and celestial, namely limitation of strength of muscle. Man muscle easier to experience fatigue.

Sticky leg

Gecho can climb vertical glass wall of hair cause which is in the form of like teeny tree at its(the footgear. This hair gives hold at glass with weak electromagnetic energy.

Gecho doesn't use chemical matter anything that its(the leg viscid.

The leg remain to underwater viscid, in vacuum chamber, even in space.

Sticky to all materials except teflon.

Way Of Gecho Does it

Intermolecular trade-offs force makes its(the leg hair sticking at equiamplitude surface

Scar gecho, hair glides on the surface.

This impulse makes tip of hair to do contact which extreme at equiamplitude surface.

Electron emerges at molecule tip of hair and equiamplitude surface; trade-offs elektrostatis makes viscid them. Its(the energy light, but trade-offs combination trap millions of tip of hair makes gecho can arrest;detain payload to 27 kilograms.

Gecho moves its(the leg with slow, angle of hair also changes, so that the trade-offs force also is broken.

Gecho Manipulator Plastics

Before usage idea of carbon nanotube emerges from Turin, in United States have been created viscid material inspiration from gecho leg. Its(the viscid energy?power is it is said ready to arrest;detain an automobile above roof.

The material so called plastics synthetic gecko. This plastics created scientist in company space and defence BAE Systems. The plastics made from material polyamide, like nylon.

As gecho leg, what arranged in layers hair so called setae, equiamplitude surface of the polymers is arranged in layers millions of hair is in the form of fungoid giving it performance to patch powerfully. Idea makes clothes SpiderMan also has emerged at the time of invention of the material.

" Window cleaner officer can climb your housing side," said Dr Sajad Haq, researcher head in Advanced Technology Center in Filton, Bristol.

Synthetic gecko, which able to be used many times and do not leave over residue, will not be sticky if touched in a flash only. " Material will become viscid when depressed," said Haq. " Interaction molekulern causing it viscid."

Synthetic gecko produced by modification engineering known as photolithography, usual used to make cip - cip silicon. Its(the engineering wearing [light/ray] to etch cupola three dimensions becomes material.

The cheaper way and can be used in bigger scale. Formerly making of material like that uses expensive electron [light/ray] lithography engineering and difficult to be used produces big scale material.

So far team Dr Haq has created some materials differing from immeasurable mushroom scale to try its(the viscid. They have also created fairish sample more than 100 sticky rectangle millimeters at equiamplitude surface anything, including dirty.

But, the team has not can compare it is ably gecho leg. " Material which we create so far ready to arrest;detain an automobile at roof," said Haq. " We have not at floor is imitating gecho viscid

Nventor GMR Reachs For Nobel Physicist


DW-WORLDDE/E-7

Committee Nobel specifies two scientists, namely Albert Fert of Prancis and German Peter Gruenberg, as peraih Nobel Fisika the year 2007. The decision is submitted [by] committee Nobel in Oslo, Swedia, Tuesday ( 9/10). Appreciation delivery of Nobel to at Gruenberg and Fert will be done coming 10 Decembers.

Both the researchers is assessed it is good to obtains appreciation of prestisius through their invention so-called effects Giant Magneto Resistance ( GMR). GMR is found [by] the year 1988 by both peraih appreciation of this finding each Nobel an new physicist effect, namely magnetic transformation weakened can create big electricity resistance.

With existence of this engineering enables indus-tri computer to develop sensitive device reads information coming into computer, starts from multifarious finite mini laptop of fitur music and video player. This engineering also enables scale harddisk can be minimized and in when at the same of its(the capacities can be enlarged.

Fenomenal

Committee Nobel haves occasion to the application of finding Fert and Gruenberg hardly fenomenal and revolutionizes engineering is getting data from harddisk. Invention they also stands is big in so many magnetic censor system.

Albert Fert is bearing 7 March 1938 is physicist which instructor in Université Paris-Sud in Orsay, Prancis and science director at laboratory with National Research Center and Thales Group. While Peter Grünberg which its(the age is one year more youngly from Fert is physicist in center research Jülich, Jerman "

This is an invention that is every day we apply. All computers which we apply, all Ipod applies this engineering, possibly except some old fashions. But, out side of that, all using engineering GMR," says scientist Swedia, Lars Bergström, professor in theoretical Fisika area and member of appreciation committee Nobel.

According to him(her, good in this engineering is people can read its(the magnet dislocation stress field is with interest smooth. This means harddisk in computer can be applied eminently and more effective. In consequence, he/she said, now all also has a real big storage capacities. Its(the example, rotator capacities MP3 which reaching is level some gigabytes.

This invention also will be applied in automobile industry, for example in anti system blacks out. Both this gets gratification 1,1 million euro.

Cellborg': fusion of microbe and machine

perfect fusion of microbe and machine for the first time, the scientists has created bacterium which can detect humidity. This invention named ' cellborg', which later will become part of devices applied to detect dangerous gas and or other substance, and at least having sensitivity four times better than fully electronic. This device also works although his(its biological division stripper has died. Scientist first of all arranges in layers a silicon chip with one life bacterium layers Bacillus cereus. Some of this microbes attachs between two chip electrodes, forms a bridge. This chip then soaked in solubility containing fairish gold particles 30 nanometers. One nanometers is sepersemilyar meter. A lef of fairish man hair 100000 nanometers.

Fairish gold particles of nano melekan will at proteins like hair at bacterium, makes them to become auriferous bridge becoming electronic circuit. Protein like this hair named acid molecules teichoic. This protein haves negative charge and provides an equiamplitude surface that particle nano gold which haves positif charge can glue to [him]. Without all these, particle nano exclusive disjunction would refuse because the same cargo and there is no bridge connecting it. Prepacked molecule by this gold particles becomes metal ferromagnetic insulator, so-called the technicians as dielectric retainer.

Supercomputer Wrought by LIPI


EV

Supercomputer owned by the existing LIPI of its(the position resides in Center Research of Physicist (Puspitek) Serpong. Besides applied by the area Physicist researchers and other researcher, supercomputer that is aflame 24 hours is also on the market generically. Handoko mentions, whosoever which will do calculation with level of high obstacle can apply the supercomputer freely.

If seen from its(the type, this very scarce supercomputer and spelled out members [by] enough on uniques because result of assembly x'self. Its(the circuit only placed at glass box formed like cupboard;locker of the size 1,5 x 2 meter. other Keunikan is supercomputer assembled by Handoko and this team some spare its(the part still using model Pentium 486.

" Pentium permanent stripper of we use, because basically of course this computer task only did counting," he said. Its(the peripheral is simple enough and assembles it is not as difficult imagined. Requirement of peripheral required is type mother board, LOUVRE and LAN card. Whereas other component like Hardisk, graphical video, modem and other not in using. Even so, performance of its(the assembly supercomputer having speed that is enough reliable. If packed into world supercomputer category, its(the assembly still above low supercomputer level.

" Predicted speed of this supercomputer can reach 150 gigaflops. As comparison for low supercomputer type of its(the speed stays at the range of 135 gigaflops," says Handoko.

Ensemble x'self

Super of computer basically is aliance from some computers taken as one. Its(the peripheral is very simple and in principle looks like computer network in office. In company and in banks, usually administrate system applies a kind of this computer ridge model, but the numbers only some and was not stringed up for the sake of calculation that is quickly.

To make it is more intelligent and has quicker performance, computer must have system which can assort a comand. This distributor system there is in one peripherals PC. Hereinafter distributable operation task to other computer circuit so-called with note. In Center Physicist Research, number of computers ( note) reachs 45

Video Streaming

With the internet came a new concept, which is referred to as streaming video. This seems like a very general term, and many people may not be aware of what the term actually means. When used on the internet, “streaming” means that a product is being sent from one place to another on a time frame. Streaming video is a video clip or movie that is being sent over real time from one place to another. This is a movie that is being constantly supplied to the individuals requesting the video. The method of the material being transferred is known as streaming, and this is not the medium that is being used. For example, there is streaming video and streaming audio. Audio and video are the mediums that are being used in those forms, but the streaming concept refers to the way that the product is being sent from one place to another over the internet or through another method. Some people do not realize that streaming media was around before the internet, but that it was not referred to as such. Since there are no so many ways in which people can receive information, including videos, many people are able to understand that there needs to be a distinction between styles of sending.

Streaming video can also be used in order to describe a television channel. In this way, an individual can acknowledge that while streaming video is not just used on the computer this is a very popular example. Still, it is used in various other methods around the home. In some homes, there are security cameras which will stream the video from one part of the home to another area in the home. Streaming does not have anything to do with the distance over which the video will travel. Rather, this merely refers to the manner in which the information gets transferred between locations. The same process can be applied to businesses and offices which is used in the home. Some alarm companies or security companies will actually allow owners to sign in on the internet from a remote location in order to view the security feeds on the cameras that are placed in the individual owner’s place of business. Streaming video is important when it comes to entertainment, such as with the television or on the internet, but it is also practical in a number of ways when it comes to security for businesses. Whether an individual wants to watch a movie on the television or check on the status of their store while they are home, streaming video can help these individuals to accomplish their goals and meet their desires. Sometimes streaming video will cost money and in order cases it will not cost the individual anything. It all depends on what is being streamed and where this is taking place. Many online sources do not charge for streaming video, but in most cases security companies and also the cable company will charge for the streaming videos that the individuals are able to enjoy.

How to get Streaming Video on Your Cell Phone

There are a number of people that have cell phones. Over the last 20 years, these phones have helped to enable many people to conveniently and effectively stay in contact with other individuals. This is especially handy when the individual is going away and will not be at a landline phone in order to receive phone calls. Instead, individuals can easily rely on cell phones to help them keep in touch with others. As the cell phone has been evolving and progressing, different aspects have begun to change and technology has more thoroughly embraced the cell phone.

As a result, we are now capable to do many different things with our cell phones, especially when they are compared to the first cell phones that were developed. One of the most popular forms today is to be able to offer individuals computer like capabilities on their cell phones. When it comes to computers, one of the most popular aspects would be the internet, which many people use for both personal and professional reasons. As a result, many people are actually capable of using their cell phones as a personal computer in order to access the internet if they need to.
From here, an individual can access some of the many different websites that are dedicated to broadcasting streaming video clips. It is not difficult to understand how to get streaming video on your cell phone, for the most part the individual merely needs to have the ability to get connected to a particular server in order to access the video file that is being broadcast from the server. It is important when individuals that are using a cell phone make sure that they have a connection to the internet, since this will be their means to accessing the information. Also, without downloading a person keeps more space on their cell phone in order to store different things as opposed to videos, including music, ring tones and other interesting bits of information and entertainment.
Cell phones have a number of different models and capabilities, and not all will be able to offer streaming videos. This is not a reflection of the individual or the phone company. It merely means that the cell phone does not currently have the capability to connect to the internet. In most cases, this can be resolved by looking into how to upgrade the cell phone or purchasing a new cell phone that would be able to play streaming videos for the individual automatically. No matter what type of situation the individual is in, without being connected to the internet, it will not be possible to see streaming video clips, and this is because the cell phone needs to connect with a server before it is able to play the streaming videos. The server is the device that will be sending out the signal for the video, which the cell phone or computer will lock on to in order to allow the individual to watch or learn from the specific video clip on the internet.

Symantec Norton Ghost : Back up Your Computer System that SPARE from MENACE Virus VICIOUS

Development of computer technology more and more day more and more sophisticated. The computer consumers also more and more is pampered with various software-software a real facilitates good walk of life of that is for academician, entrepreneurs and others. Software data processor like Microsoft Office is software a real good for various circles either that is white colars student and also institution. Software Ensiklopedia like Encarta is software which good for student circle. Software Billing Explorer and also CCTV is some software developed to facilitate our walk of life. Both this software usualy used by the entrepreneurses is being implements business.

But, development of fast computer simply is accompanied also by development of virus that is more and more malignant. For example just of virus naruto.sys.vbs capable to confuse appearance icon at desktop computer and hides important data of computer users. This virus also makes computer system to become intruding. Viral spreading these days very easy out of one computers to other computer passed data storage media like flashdisk. When striking flashdisk to a PC or Laptop in at once PC or Laptop can be attacked virus from flashdisk. Most virus will make autoplay at flashdisk so that when flashdisk steps into a computer hence automatically the virus will proceed and infection direct of files in computer.

It is not strange if now every computer consumer coped memaintaince their computer with antivirus which must always is updated. Usage of Antivirus sometime not effective because not all viruses can detected by Antivirus. Sometime the virus file can get away from scanning Antivirus more than anything else if its(the Antivirus didn't update. Hardly merestore computer difficult to which has been attacked virus with system restore provided by the side of Microsoft. Therefore, it is better memback-up our computer system to at the time of computer still be in god condition. That way, if happened external thing suspect like at one time computer is attacked [by] virus or happened corrupts at computer system, without needing is confused and hesitates, we can overcome the thing in calculation minute. Ability of Symantec Norton Ghost can invert computer system we to return in the situation normal in calculation 5-10 minutes.

But beforehand, we memback-up computer system we must apply Symantec Norton Ghost. Result of its(the back-upan is image with extension GHO which fairish of 2 GB is more. Memback-up system with Symantec Norton Ghost must as according to its(the stages;steps because wrong step will make data at your hardisk are format with the meaning risk losing of data. Therefore, ensures that you to know correct step before you will apply this software. If knowing truly this software benefit hence this software would hardly assists the computer consumers so that you are not necessarily fear again from malignant virus threat.
