Further the developed process is based on the continuous and mass-produced process of carbon fiber making it much easier for full-scale commercialization.
since this process is based on the continuous and mass-produced process of carbon fiber. Explore further:
To synthesize the carbon fibers, the chemists first prepare a porous, tubular silica template, starting from commercially available,
but nonporous fibers. This template is filled then with a special mixture of carbon, silicon dioxide and surfactants,
and the fibers themselves are correspondingly more stable.""Nanostructured materials have great potential for the efficient conversion
much better than other carbon fibers,"said Mauricio Terrones, professor of physics, chemistry and materials science and engineering, Penn State."
"We believe that pockets of air inside the fiber keep it from being brittle.""This method opens up multiple possibilities for useful products, according to Terrones and colleagues.
For instance, removing oxygen from the graphene oxide fiber results in a fiber with high electrical conductivity. Adding silver nanorods to the graphene film would increase the conductivity to the same as copper,
and wound on itself with an automatic fiber scroller, resulting in a fiber that can be knotted
and stretched without fracturing. The researchers reported their results in a recent issue of ACSNANO."
special fibers could also be developed with nanostructures to conduct and store energy. More immediate applications could be seen in the design
That could lead to specially treated clothing fibers being able to hold enough power for big tasks.

#Flexible supercapacitor raises bar for volumetric energy density Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing
The fiber-structured hybrid materials offer huge accessible surface areas and are highly conductive. The researchers have developed a way to continuously produce the flexible fiber enabling them to scale up production for a variety of uses.
To date they've made 50-meter long fibers and see no limits on length. They envision the fiber supercapacitor could be woven into clothing to power medical devices for people at home or communications devices for soldiers in the field.
Or they say the fiber could be a space-saving power source and serve as energy-carrying wires in medical implants.
Yuan Chen a professor of chemical engineering at NTU led the new study working with Dingshan Yu Kunli Goh Hong Wang Li Wei and Wenchao Jiang at NTU;
Qiang Zhang at Tsinghua; and Liming Dai at Case Western Reserve. The scientists report their research in Nature Nanotechnology.
To improve the energy density by volume the researchers designed a hybrid fiber. A solution containing acid-oxidized single-wall nanotubes graphene oxide and ethylenediamine
Sheets of graphene one to a few atoms thick and aligned single-walled carbon nanotubes self-assemble into an interconnected prorous network that run the length of the fiber.
The process using multiple capillary columns will enable the engineers to make fibers continuously and maintain consistent quality Chen said.
The researchers have made fibers as long as 50 meters and found they remain flexible with high capacity of 300 Farad per cubic centimeter.
In testing they found that three pairs of fibers arranged in series tripled the voltage
Three pairs of fibers in parallel tripled the output current and tripled the charging/discharging time compared to a single fiber operated at the same current density.
When they integrate multiple pairs of fibers between two electrodes the ability to store electricity called capacitance increased linearly according to the number of fibers used.
Using a polyvinyl alcohol/phosphoric acid gel as an electrolyte a solid-state micro-supercapacitor made from a pair of fibers offered a volumetric density of 6. 3 microwatt hours per cubic millimeter
which is comparable to that of a 4-volt-500-microampere-hour thin film lithium battery. The fiber supercapacitor demonstrated ultrahigh energy density value
while maintaining the high power density and cycle stability. We have tested the fiber device for 10000 charge/discharge cycles
and the device retains about 93 percent of its original performance Yu said while conventional rechargeable batteries have a lifetime of less than 1000 cycles.
The fiber supercapacitor continues to work without performance loss even after bending hundreds of times Yu said.
and structurally consistent over their length the fibers can also be woven into a crossing pattern into clothing for wearable devices in smart textiles.
They plan to scale up the technology for low-cost mass production of the fibers aimed at commercializing high-performance micro-supercapacitors.
In addition The team is interested also in testing these fibers for multifunctional applications including batteries solar cells biofuel cells

The approach starts with testing fibers and matrix materials; then the tests get, as the handbook states,"increasingly more complicated,"until reaching the level of structural subcomponent (or higher).

#Food emulsifiers linked to gut bacteria changes and obesity While it has been suggested long that gut microbiota disturbances are involved in inflammatory bowel disease (IBD), obesity and metabolic syndrome,
the new findings suggest emulsifiers might be partially responsible for this disturbance and the increased incidence of these diseases.
The study used mice to test the effect of two common emulsifiers-carboxymethylcellulose and polysorbate-80-on the microbiome make up
and metabolism, finding that relatively low-level concentrations of the emulsifiers resulted in distinct alterations to the gut microbial ecosystem (microbiota) and led to low-grade inflammation and the onset of metabolic syndrome.
the research team reported that the emulsifier-induced metabolic syndrome was associated with microbiota encroachment, altered species composition and increased pro-inflammatory potential.#
Sanders said the research team's#conclusion that overeating in humans may be driven by food additives is'headline grabbing
as we onlt consume tiny amounts of any emulsifier ingredients in the foods we eat.#
#This paper reports the effects in mice of very high intakes of two carbohydrate-based food additives (carboxymethyl cellulose E466 and polysorbate-80 E433...
so we considered what modern additions to the food supply might possibly make gut bacteria more pro-inflammatory."
"Chassaing and his colleagues theorised that emulsifiers might affect the gut microbiota to promote these inflammatory diseases
Mice were fed two commonly used emulsifiers, polysorbate 80 and carboxymethylcellulsose, at doses seeking to model the broad consumption of the numerous emulsifiers that are incorporated into almost all processed foods,
they said. The team found that emulsifier consumption changed the species composition of the gut microbiota
-and did so in a manner that made it more pro-inflammatory. According to the team, the altered microbiota had enhanced capacity to digest
In contrast, in mice with normal immune systems, emulsifiers induced low-grade or mild intestinal inflammation and metabolic syndrome, characterized by increased levels of food consumption, obesity, hyperglycemia and insulin resistance.
However, the effects of emulsifier consumption were eliminated in germfree mice which lack a microbiota, said the team.
Who also showed that transplant of the microbiota from emulsifiers-treated mice to germfree mice was enough to transfer some parameters of low-grade inflammation and metabolic syndrome.
Chassaing and his team said this indicates that the microbiota has a#central role#in mediating the adverse effect of emulsifiers.
The team is now testing additional emulsifiers and designing experiments to investigate how emulsifiers affect humans.
If similar results are obtained, it would indicate a role for the food additive in driving the epidemic of obesity,
its interrelated consequences and a range of diseases associated with chronic gut inflammation, said the authors.
While detailed mechanisms underlying the effect of emulsifiers on metabolism remain under study, Chassaing and co pointed out that avoiding excess food consumption is of paramount importance."
"We do not disagree with the commonly held assumption that overeating is a central cause of obesity
and metabolic syndrome,"said Andrew Gewirtz, senior author of the study.##Rather, our findings reinforce the concept suggested by earlier work that low-grade inflammation resulting from an altered microbiota can be an underlying cause of excess eating."
