The study also suggests the broader potential for adapting nanoscale drug-delivery techniques developed for use in environmental remediation. hat we can apply some of the highly sophisticated,
#Mood-changing wearable tech sets pulses racing The makers of'doppel'call it the next generation of wearable technology-one that can actually change the mood of the user.
Co-creator Nell Bennett explained how doppel represents truly empathic wearable technology instead of the current crop that often just monitor the body's activity."
and shape to a wristwatch, but with the active mechanics positioned on the sensitive inside part of the wrist.
Bilicki, along with the rest of Team Turquoise, believe doppel is a unique and game-changing addition to the burgeoning wearable technology market."
But scientists have developed now a novel nanowire coating for clothes that can both generate heat
and trap the heat from our bodies better than regular clothes. They report on their technology,
breathable mesh materials that are flexible enough to coat normal clothes. When compared to regular clothing material,
the special nanowire cloth trapped body heat far more effectively. Because the coatings are made out of conductive materials,
they can also be warmed actively with an electricity source to further crank up the heat. The researchers calculated that their thermal textiles could save about 1
000 kilowatt hours per person every year--that's about how much electricity an average U s. home consumes in one month h
Use of nanotechnology in cosmetics and pharmaceuticals A Faculty of science Universiti Putra Malaysia (UPM) lecturer Professor Dr Mahiran Basri not only succeeded in producing new useful substances made of oils
In the field of cosmetics for instance she said there are antioxidants and antiaging substances through the use of nanotechnology those substances can easily absorb through the skin.
when constructed in future helmets and bumpers, could reduce or even prevent many of the blunt-force injuries we see today."
as well as miniature NS honeycomb cells, from nylon using selective laser sintering for experimentation. NS honeycombs can be made from a variety of materials to suit distinct applications.
Subsequent custom compression and drop tests, designed and fabricated at UT Austin, have confirmed the NS honeycomb structures'predicted energy-absorbing behavior and resilience.
In addition, PLA is biocompatible and thus suitable for medical use, for instance in absorbable suture threads.
#Nanotech transforms cotton fibers into modern marvel Marcia Silva da Pinto, postdoctoral researcher, works on growing metal organic frameworks onto cotton samples to create a filtration system capable of capturing toxic gas,
as Juan Hinestroza looks on. Juan Hinestroza and his students live in a cotton-soft nano world,
where they create clothing that kills bacteria, conducts electricity, wards off malaria, captures harmful gas and weaves transistors into shirts and dresses. otton is one of the most fascinating and misunderstood materials,
said Hinestroza, associate professor of fiber science, who directs the Textiles Nanotechnology Laboratory at Cornell. n a nanoscale world
and that is our world we can control cellulose-based materials one atom at a time. he Hinestroza group has turned cotton fibers into electronic components such as transistors and thermistors,
so instead of adding electronics to fabrics, he converts the fabric into an electronic component. reating transistors
and other components using cotton fibers brings a new perspective to the seamless integration of electronics
and textiles, enabling the creation of unique wearable electronic devices, Hinestroza said. Taking advantage of cotton irregular topography, Hinestroza and his students added conformal coatings of gold nanoparticles,
as well as semiconductive and conductive polymers to tailor the behavior of natural cotton fibers. he layers were so thin that the flexibility of the cotton fibers is preserved always,
Hinestroza said, ibers are everywhere from your underwear, pajamas, toothbrushes, tires, shoes, car seats, air filtration systems and even your clothes. bbey Liebman 0 created a dress using conductive cotton threads capable of charging an iphone.
With ultrathin solar panels for trim and a USB charger tucked into the waist, the Southwest-inspired garment captured enough sunshine to charge cell phones
and other handheld devices allowing the wearer to stay plugged in. The technology may be embedded into shirts to measure heart rate
or analyze sweat, sewn into pillows to monitor brain signals or applied to interactive textiles with heating and cooling capabilities. revious technologies have achieved similar functionalities,
but those fibers became rigid or heavy, unlike our yarns, which are friendly to further processing, such as weaving, sewing and knitting,
Hinestroza said. Synthesizing nanoparticles and attaching them to cotton not only creates color on fiber surfaces without the use of dyes,
but the new surfaces can efficiently kill 99.9 percent of bacteria, which could help in warding colds, flu and other diseases.
Two of Hinestroza students created a hooded bodysuit embedded with insecticides using metal organic framework molecules,
or MOFS to fend off malarial mosquitoes. Malaria kills more than 600,000 people annually in Africa. While insecticide-treated nets are common in African homes
the antimalarial garment can be worn during the day to provide extra protection and does not dissipate like skin-based repellants.
Other students have used MOFS to create a mask and hood capable of trapping toxic gases in a selective manner.
MOFS, which are clustered crystalline compounds, can be manipulated at the nano level to build nanoscale cages that are the exact same size as the gas they are trying to capture. e wanted to harness the power of these molecules to absorb gases
and incorporate these MOFS into fibers, which allows us to make very efficient filtration systems,
Hinestroza always looks for new ways to employ cotton as a canvas for creating infinite modern uses. e want to transform traditional natural fibers into true engineering materials that are multifunctional
but have it remain flexible and as comfortable as a t-shirt or an old pair of jeans. c
