Adhering nanoparticles of iron oxide to nylon fiber is done in three ways: electrospraying, which facilitates uniform nanoparticle placement in the fibers;
layer-by-layer assembly, where particles are coated on the fiber electrostatically; or chemical bonding. or the membrane, it important to evaluate particle retention and stability,
Trejo explained. ou would want the nanoparticles to stay on the Nylon 6 membranes so the material can have function throughout the life use.
Researchers in professor Margaret Frey lab create fibers hundreds of times thinner than a human hair that can capture toxic chemicals and pathogens.
The fibers have been designed and combined to prevent the spread of agricultural chemicals and to capture toxic substances in liquids.
The fibers are a fast, easy and inexpensive way to concentrate on E coli, cholera toxin or carcinogens and to improve accuracy of detection.
Eventually, these fibers will be part of devices as inexpensive and easy to use as home pregnancy tests and will diagnose diseases without requiring specialized laboratories particularly useful in regions with limited access to doctors and hospitals.

Electrospinning uses an electrical charge to create very thin fibers from a liquid. Researchers tested the bandages

Furthermore, the wavelength range of these fibers is restricted to the transparency of silica. The release stories for this laser mention that the infrared wavelengths used here are safer for the eye than either visible or UV radiation.
#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...
"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."

#Fiber-like light emitting diodes for wearable displays A research team at Korea Advanced Institute of Science
and Technology (KAIST) has developed fiber-like light emitting diodes, applicable to wearable displays. Professor Kyung-Cheol Choi and his research team from the School of Electrical engineering at KAIST have developed fiber-like light emitting diodes,
which can be applied in wearable displays. The research findings were published online in the July 14th issue of Advanced Electronic Materials.
Instead, they focused on fibers, a component of fabrics, and developed a fiber-like light emitting diode that has the characteristics of both fabrics and displays.
The essence of this technology, the dip coating process, is to immerse and extract a three dimensional (3-D) board that looks like a thread in a solution.
The researchers said that this technology would accelerate the commercialization of fiber based wearable displays

#Stretchable Conducting Fiber Provides Super Hero Capabilities The list of potential applications for a new electrically conducting fiberrtificial muscles,

An international research team based at the University of Texas at Dallas initially targeted the new super fiber for artificial muscles and for capacitors
