#How the world's tiniest film can transform computers Researchers at IBM have made the world's smallest movie.

But quite apart from breaking film-making records, what else can the world's smallest stop-motion movie tell us?

since been verified by the Guinness World records as the world's smallest stop-motion film. The one-minute video is made from carbon

In the short film, Champ was seen taking out a bank of computers. While the system is likely to be still several years away from being fielded,

So the thermal oscillations of Arnold and Crandall's platinum film also generated a sound wave#without any of the cumbersome,

a thin, transparent film made from microscopic tubes called carbon nanotubes (CNTS), aligned parallel to the plane of the film.

These tiny tubes, whose walls are one atom thick and made from pure carbon, are need highly robust

gasgetting CNT films to emit sound is not the same as producing good-quality sound over the whole frequency range of human hearing,

Another way to improve the sound output is to make the surface area of the film bigger.

The CNT films will need probably to be enclosed and immersed in xenon, for example, which would pose serious challenges for making robust"wearable#speakers.

By the time the story was adapted loosely for the big screen in the 1973 film Soylent Green,

We explore realms as varied as synthetic biology, surreal digital theory, film and animation, interaction design,

dark-field imaging setup using an inexpensive external lens, thin-film interference filters, a miniature dovetail stage and a laser diode that excites the fluorescently labeled DNA molecules"for the demonstration.

In comparison to conventional crystalline and thin-film PV technologies, New Energy#s Solarwindow#has numerous advantages:*

and avoid causing any heat damage to the film. The new materials provide several advantages,

thin-film solar cells, are hard to overestimate. In the words of Professor Selleri: echanical scribing will disappear very quickly from the PV industry,

The whey is used as a bio-coating a biodegradable film-for the plastic, offering additional protection while also being recyclable.

and other viruses microbicides can be inserted into the vagina prior to intercourse as a gel cream foam sponge suppository or film.

and topical medications in the form of gels and films are just starting to be developed.

Drugs in film form take at least 15 minutes to fully dissolve in the body, and the volume of gels must be large enough to deliver a full dose

Carbon nanotube thin films are extremely good absorbers of electromagnetic light he explains. In the terahertz range the film a mix of metallic

and semiconducting nanotubes soaks up all of the incoming terahertz radiation. rying to do that with a different kind of material would be nearly impossible

transistors, and diodes that guide magnetic beads and single cells tagged with magnetic nanoparticles through a thin liquid film.

and bacterial films, resistant to antibiotics, can colonize the implant itself. To catch infection early without having to resort to invasive measures could lead to faster treatment. his is a very attractive detection mechanism for monitoring the condition of the implant

#dgy films are perfect catalysts for fuel cells Chemists have found an easy and inexpensive way to create flexible films from molybdenum disulfide a versatile chemical compound with edges that are highly efficient catalysts.

The nanoporous films maximize the amount of exposed edge increasing its potential uses for energy storage

and a lot of edge as though the material had drilled bore holes all the way through. he new film catalyzes the separation of hydrogen from water

First they grew a porous molybdenum oxide film onto a molybdenum substrate through room-temperature anodization an electrochemical process with many uses

The film was exposed then to sulfur vapor at 300 degrees Celsius (572 degrees Fahrenheit) for one hour.

The films can also serve as supercapacitors which store energy quickly as static charge and release it in a burst.

The researchers built supercapacitors with the films; in tests they retained 90 percent of their capacity after 10000 charge-discharge cycles

and grow a film on just about any surface similar to the bacterial film that forms on teeth.

By keeping this process on the surface of the film the bacteria are exposed not to uranium

GRAPHENE SLURRY FILM The researchers made a thin film of graphene oxide by chemically exfoliating graphite into graphene flakes,

it becomes a transparent film that can be lifted carefully off without tearing. The film is then cut into narrow strips

and wound on itself with an automatic fiber scroller, resulting in a fiber that can be knotted

They have filed also a patent for this technology due to its commercial potential. e use a simple polymer-based film to remove the impurities

These films separate molecules based on size the smaller ones such as hydrogen pass through, while larger ones such as carbon dioxide and nitrogen are slowed down. ou can have multiple membranes in a row

Zhu was presenting his technique for spraying nanoribbons films and Volman recognized the potential. ristine graphene transmits electricity ballistically

now that they re being produced in industrial quantities. ow we re going to the next levelhe says noting that GNR films made into transparent films might be useful for deicing car windshields a project the lab intends to pursue.

Once dissolved the semiconductor solution can be applied as a thin film to substrates like glass and silicon.

Once heated the solvent evaporates leaving behind only a high-quality film of crystalline semiconductor##perfect for use in electronics. t s inexpensive and easily scalablesays Richard Brutchey a chemistry professor at the University of Southern

it s as big a leap going from film to semiconductors as it is going from semiconductors to these superconductors.

Thin films of such materials are rife with defects which waste power and greatly lower the films performance in circuitsâ##a problem cell phone companies would like to solve.

Thin film could be the answer. An atomic-resolution electron micrograph reveals its design. It looks like bricks and mortar with very specific spacing between the well-defined interfaces.

The layered structure is orgivingwith regard to defects Schlom says. The ortarportions seem to soak up many of the defects

The researchers led by Rice graduate student Changsheng Xiang produced thin films of the composite material by solution casting GNRS treated with hexadecane and TPU a block copolymer of polyurethane that combines hard and soft materials.

They tested GNR/TPU films by putting pressurized nitrogen on one side and a vacuum on the other side.

For films with no GNRS the pressure dropped to zero in about 100 seconds as nitrogen escaped into the vacuum chamber.

and assembly of uniform films on each wafer or substrate resulting in patterns with essentially only one characteristic feature size

or spatially placed over a wafer. his invention to use ink-jet printing to deposit different block copolymer films with high spatial resolution over the substrate is highly enabling in terms of device design

To make their uniquely compact electrode Li s team exploited an adaptive graphene gel film they had developed previously.

#Pi-powered Kinograph makes preserving film heritage affordable As the Raspberry Pi Foundation (RPF) has worked to make computing more accessible,

whose Pi-powered Kinogarph digitizes old film stock at a fraction of the cost of conventional off-the-shelf systems.

such as rollers that can take different sized film, and a few components that can be cheaply sourced over the internet.

As a point of comparison, the cost to digitize 50 films on reels at a film lab would cost around $480, 000,

"the cost of digitization is prohibitive for anybody with more than a few films.""This is as true for individuals with private collections as it is for libraries, museums and other public institutions.

and 8 mm films at high-definition resolutions with sound, the Kinograph makes preserving our cultural heritage much more affordable.

and around 50 percent of the films with audio made before 1950 have been lost to the ages.

the printing machine can produce up to 100 metres of layered film per minute. The manufacturing of the OPV cells is affordable;

It would then lay a membrane on the structure of either thin-film PV or reflecting materials,

as the same material can also be adapted to make a##transparent conductive film,##in other words a see-through electronic circuit,

According to the blurb,##the film details plastic s path over the last 100 years and provides a wealth of expert interviews on practical and cutting edge solutions to recycling, toxicity and biodegradability.##

Brooks Kincaid, the company s cofounder and president, says the batteries combine the best features of thin-film lithium batteries and printed batteries.

For example, a PVC sheet sandwiched between two films of rigid polyester featuring slits of different sizes contracts

creating different angles where the edges of the polyester films press against each other. Producing the pattern of slits is quite a difficult process as every edge in the system moves at the same time,

they coated it with a thin film of alumina (aluminum oxide). The best configuration, a honeycomb lattice with a 50 nanometer coat of alumina, is less dense than waterthat is,

She said the finished film will have pedicabs, bicycle messengers, food delivery and, yes, pizza guys. t would be great if a big company,

Canning is a longtime film editor, and"Less Car More Go"will be her first film as a director.

She has modest goals of maybe being able to hire an assistant, pay for music rights,

Other films were studded with quantum dots, or tiny crystals that exhibit quantum mechanical properties. The cells were further able to communicate with each other

Our electronic whiskers consist of high-aspect-ratio elastic fibers coated with conductive composite films of nanotubes and nanoparticles.

what the paper describes as highly tunable composite films of carbon nanotubes and silver nanoparticles that are patterned on high-aspect-ratio elastic fibers.

The resulting films conduct electricity better than any other sample of graphene produced in the past. Until recently

The results in Hong's case were relatively large, high-quality films of graphene just a few atoms thick and several centimetres wide.

which produces bigger pieces of film, "will tremendously influence the speed of development in this area".

Nature News In the film Eternal Sunshine of the Spotless Mind, a couple have their memories of each other wiped when their relationship ends badly.

Diamond nanocrystals immersed in a cell's cytoplasm could essentially produce real-time films of the activity of single molecules,

it did so in neat droplets rather than the films that would form on non-hydrophobic materials such as silicon.

A hydrophobic coating made of tough ceramic would prevent films of water forming on the blades,

where films of water on the blades can, if they freeze in cold weather, lead to catastrophic failures.

as we have learned all from countless heist films, is itself hard enough to cut glass. Or maybe it s a devious scheme predicated on boring a hole into the depths of the planet with the world s hardest drill bit.

The film is layered between the LCD s stack of light filters, diffusers and polarizers, and similarly converts raw blue light into white light made up of pure colours.

researchers made extremely small perforations in a structure made of two thin films of silver separated by a film of silica.

Then, the researchers poked minuscule holes into the top layer of silver film, which was a scant 25 nanometers deep.

To do so, they sandwiched a layer of quantum dots, a few nanometers thick, between two organic thin films.

#Moneyball for business Michael Lewis 2003 book Moneyball and the 2011 film adaptation detailed how the Oakland athletics used analytics primarily derived from players on-base percentages to assemble a competitive team despite financial constraints.

and cloth notoriously difficult features to animate realistically for films including he Hobbitand Disney angled. he eye is very good at picking up what physical and what not,

To control the nanotubes growth the researchers first cover the emitter array with an ultrathin catalyst film

you might think of the popular science-fiction films inority Report (2002) or ron Man (2008). In those films, the protagonists use their hands

or wireless gloves to seamlessly scroll through and manipulate visual data on a wall-sized, panoramic screen.

But the brain behind those Hollywood interfaces, MIT alumnus John Underkoffler 8, SM 1, Phd 9 who served as scientific advisor for both films has been bringing a more practical version of that technology to conference rooms

but the world of movies came calling first. he world largest focus groupunderkoffler was recruited as scientific advisor for Steven Spielberg inority Reportafter meeting the film crew,

In such spectacular science-fiction films, technology competes for viewer attention and, yet, it needs to be simplified so viewers can understand it clearly. hen you take technology from a lab like at MIT,

and you need to show it in a film, the process of refining and simplifying those ideas

because the perovskite photovoltaic material takes the form of a thin film just half a micrometer thick,

To perform this study the team deposited graphene on top of an insulating layer with a thin metallic film beneath it;

this casting plate is immersed then in a nonsolvent bath to induce precipitation to form a film.

Since the solutions form a single sheet of film there is no need for bonding layers together

is still higher than the 24 frames per second standard in film. With the technology that has historically been used to produce glasses-free 3-D images known as a parallax barrier simultaneously projecting eight different viewing angles would mean allotting each angle one-eighth of the light emitted by the projector

While these experiments were carried out using a material called tetracene a well-studied archetype of a molecular crystal the researchers say that the method should be applicable to almost any crystalline or thin-film material.

and films studded with quantum dots or tiny crystals that exhibit quantum mechanical properties. They also engineered the cells

If both are present the film will contain a mix of tagged and untagged fibers.

so that actors in the background of a television program or film do not distract viewers attention from the main actors for example.

when they are assembled in a film. However, the UW-Madison researchers pioneered a new technique,

Our carbon nanotube transistors are an order of magnitude better in conductance than the best thin film transistor technologies currently being used commercially

film-like devices designed to detect pressure, read brain activity, monitor heart rate or perform other functions.

and polymers without the involvement of conventional microfabrication techniques yet the thickness and uniformity of the printed films are two of the critical parameters that determine the performance

Most conventional lithography uses a variety of techniques to focus light on a photosensitive film to create 2-D patterns.

The NC State researchers took a different approach placing nanoscale polystyrene spheres on the surface of the photosensitive film.

And ultimately we want to look at ways of controlling the placement of particles on the photosensitive film in patterns other than uniform arrays.

She precipitates the precious metal from an aqueous solution onto a pretreated film with many tiny channels.

the film is dissolved then. The technique itself is not new, but Felix has modified it:""The chemicals that are used usually for this were just too toxic for me."

The film with the nanochannels is placed merely in the precipitation bath.""It's really unbelievable that aqueous solutions

The only thing that is not green in the procedure is the film that is used as the template, notes Ensinger.

the films still consist of polycarbonate also made or of polyethylene terephthalate (PET). In order to create the miniature plastic channels that define the shape,

a round film is bombarded vertically with an ion beam. Each ion leaves a straight track in the film

which then becomes a small hole, or, when seen through the microscope: a channel that is then etched.

After the film is dissolved, the result is-depending on the experimental conditions-a collection of individual nanotubes or an array of hundreds of thousands of interconnected tubes.

For example, a company in the USA produces similarly perforated films with smaller accelerators.""The films are defined not as well as ours are,

but they are also suitable, "says Münch. Furthermore, they are inexpensive: a film roughly the size of a sheet of paper costs only a few euros.

Ensinger says that the price of gold is not a factor because the amounts that are required are small:"

and Engineering in Singapore is helping to circumvent this limitation using a technique known as'directed self-assembly of nanoparticles'(DSA-n). This approach takes spherical nanoparticles that spontaneously organize into ordered two-dimensional films

The templates impose geometric constraints that force the films to organize into specific nanoscale patterns.

The researchers combined semiconductor nanorods and carbon nanotubes to create a wireless light-sensitive flexible film that could potentially replace a damaged retina.

and semiconductor nanorod film will serve as a compact replacement for damaged retinas. We are still far away from actually replacing the damaged retina said Dr. Bareket.

and if the films were covered with catalytic nanoparticles such as platinum. The discovery makes monolayers of graphene

To do so, they sandwiched a layer of quantum dots, a few nanometers thick, between two organic thin films.

For his work on thin film and plasma technologies Fan was named researcher of the year for the Jerome J. Lohr College of Engineering.

Since last fall Fan has been collaborating with Wintek on ways of producing more efficient better performing materials such as silicon and carbon thin films for the company's displays.

The high-energy plasma can deposit highly transparent and conductive thin films create high quality semiconductors and pattern micro-or nanoscale devices thus making the display images brighter and clearer.

#New way to move atomically thin semiconductors for use in flexible devices Researchers from North carolina State university have developed a new way to transfer thin semiconductor films

and can perfectly transfer the atomic scale thin films from one substrate to others without causing any cracks.

At issue are molybdenum sulfide (Mos2) thin films that are only one atom thick first developed by Dr. Linyou Cao an assistant professor of materials science and engineering at NC State.

The ultimate goal is to use these atomic-layer semiconducting thin films to create devices that are extremely flexible

but to do that we need to transfer the thin films from the substrate we used to make it to a flexible substrate says Cao who is senior author of a paper on the new transfer technique.

You can't make the thin film on a flexible substrate because flexible substrates can't withstand the high temperatures you need to make the thin film.

Cao's team makes Mos2 films that are an atom thick and up to 5 centimeters in diameter.

The researchers needed to find a way to move that thin film without wrinkling or cracking it

which is challenging due to the film's extreme delicacy. To put that challenge in perspective an atom-thick thin film that is 5 centimeters wide is equivalent to a piece of paper that is as wide as a large city Cao said.

Our goal is to transfer that big thin paper from one city to another without causing any damage or wrinkles.

Existing techniques for transferring such thin films from a substrate rely on a process called chemical etching

or contaminate the film. Cao's team has developed a technique that takes advantage of the Mos2's physical properties to transfer the thin film using only room-temperature water a tissue and a pair of tweezers.

Mos2 is hydrophobic-it repels water. But the sapphire substrate the thin film is grown on is hydrophilic-it attracts water.

Cao's new transfer technique works by applying a drop of water to the thin film

and then poking the edge of the film with tweezers or a scalpel so that the water can begin to penetrate between the Mos2 and the sapphire.

Once it has begun to penetrate the water pushes into the gap floating the thin film on top.

The researchers use a tissue to soak up the water and then lift the thin film with tweezers and place it on a flexible substrate.

The whole process takes a couple of minutes. Chemical etching takes hours. The water breaks the adhesion between the substrate

and the thin film-but it's important to remove the water before moving the film Cao says.

Otherwise capillary action would case the film to buckle or fold when you pick it up.

These semiconducting nanowires could also replace thin films that cover today's solar panels. Current panels can process only 20 percent of the solar energy they take in.

#Dual-purpose film for energy storage hydrogen catalysis: Chemists gain edge in next-gen energy Rice university scientists who want to gain an edge in energy production

Tour and his colleagues have found a cost-effective way to create flexible films of the material that maximize the amount of exposed edge

The new film was created by Tour and lead authors Yang Yang a postdoctoral researcher; Huilong Fei a graduate student;

First they grew a porous molybdenum oxide film onto a molybdenum substrate through room-temperature anodization an electrochemical process with many uses

The film was exposed then to sulfur vapor at 300 degrees Celsius (572 degrees Fahrenheit) for one hour.

The films can also serve as supercapacitors which store energy quickly as static charge and release it in a burst.

The Rice lab built supercapacitors with the films; in tests they retained 90 percent of their capacity after 10000 charge-discharge cycles and 83 percent after 20000 cycles.

http://arxiv. org/ftp/arxiv/papers/1407/1407.1359. pdfabstractwe have investigated thermal conductivity of graphene laminate films deposited on polyethylene terephthalate substrates.

depositing thin films of a uniquely designed polymer on a template so that it self-assembles into neat, precise, even rows of alternating composition just 10 or so nanometers wide.

the BCPS in question will form a thin film in a pattern of narrow, alternating stripes of the two polymer compositions.

but down inside the film, it isn't."Kline's group, working with IBM, demonstrated a new measurement technique*that uses low energy

or"soft"X rays produced by the Advanced Light source at Lawrence Berkeley National Labs to probe the structure of the BCP film from multiple angles.

Because the film has a regular repeating structure, the scattering pattern can be interpreted, much as crystallographers do,

to reveal the average shapes of the stripes in the film. If a poor match between the materials causes one set of stripes to broaden out at the base, for example,

**While X-ray scattering can measure average properties of the films, Liddle's group, working with MIT, developed a method to look, in detail,

at individual sections of a film by doing three-dimensional tomography with a transmission electron microscope (TEM).*

and then MWCNT@S and VACNTS were assembled into macro-CNT-S films via the dispersion in ethanol followed by vacuum filtration",Zhe Yuan,

Furthermore the process is easily scalable for creating large-area films which will be highly useful as electrodes and membranes for energy generation or storage.

and uniformly thin films the flat-plane emission device has the potential to provide a new approach to lighting in people's life style

To control the nanotubes'growth the researchers first cover the emitter array with an ultrathin catalyst film

"We coated these crystals with a thin metal film, heated the surface with a laser beam,

Project leader Dr Sharath Sriram, co-leader of the RMIT Functional Materials and Microsystems Research Group, said the nanometer-thin stacked structure was created using thin film, a functional oxide

"The thin film is designed specifically to have defects in its chemistry to demonstrate a'memristive'effect where the memory element's behaviour is dependent on its past experiences,

and colleagues from the RIKEN Center for Emergent Matter Science the University of Tokyo and Hiroshima University have discovered that ultrathin films of a semiconducting material have properties that form the basis for a new kind of low-power electronics

Iwasa and his team created films consisting of one to four atomic layers of molybdenum disulfide.

Most previous studies of this material focused on films in which each layer is the mirror image of the one below.

Instead the atoms in each molybdenum disulfide layer in the films created by Iwasa's team were shifted slightly from those in the two-dimensional level beneath (Fig. 1). This breaking of the film's symmetry meant that the researchers were also able to harness the spin of electrons.

since 2001 and our technology has achieved now the fabrication of large area(>1000 mm2) ultra-thin films only a few atoms thick.

Our ability to not only synthesise large uniform thin films but also to transfer these films to virtually any substrate has led to increased demand for our materials.
