A triboelectric nanogenerator (TENG) utilizes charges arising from friction similar to the static we experience on dry winter days; and by nanostructuring the materials in a TENG device, the produced energy could be amplified by increasing the contact area of the surfaces. In a step toward the commercialization of triboelectric nanogenerator (TENG) devices, researchers have presented a novel approach that uses TENG technology to develop battery-free, self-powered electronic toys.

Imagine you are fast asleep in your bedroom when a fire breaks out somewhere else in your house. Fortunately, you have nanotechnology-enhanced wallpaper that detects the fire and automatically rings an alarm. Realizing this idea, scientists have developed a 'smart' wallpaper based on highly flexible fire-resistant inorganic paper embedded with ultralong hydroxyapatite nanowires that serve as the substrate and graphene oxide as the thermosensitive sensor.

With a focus on using eco-friendly materials such as fabrics worn in daily life (nylon, jeans, cotton, etc.), researchers have developed and demonstrated an innovative product for scavenging biomechanical energy. The team's Smart Mobile Pouch Triboelectric Nanogenerator (SMP-TENG) can generate electricity from lateral sliding and vertical contact and separation with freestanding fabrics; it also can serve as a self-powered emergency flashlight and self-powered pedometer.

Many of the electronic devices we use in our daily life rely on liquid crystal display (LCD) technologies. LCDs get their name from the special liquid crystal solution that is contained between two thin glass plates inside the display. An electric field applied across the liquid crystal layer changes optical properties of the liquid crystals thus enabling their use in displays. A new paper reports several interesting size effects including monotonous and non-monotonous dependence of the total concentration of mobile ions in liquid crystals on the thickness of the cell and/or on the concentration of nanoparticles.

There is an often-asked question: 'When are we finally going to start seeing nanotechnology products on the market?' As a matter of fact, the average home is already filled with products enhanced or reliant upon nanotechnology. In fact, there are several online repositories listing the more than 2,000 commercially available products that incorporate nanotechnology. The application of nanotechnology in some areas, such as batteries, microelectronics and sunscreens is relatively well known. Let's take a virtual tour through a home to see what else we can find.

Botulinum neurotoxins (BoNTs) are the most poisonous substances known to humans, with a median lethal dose (LD50) of 1ng per kg of body weight and are the cause of the life-threatening neuroparalytic illness botulism. Recent assays are very promising for practical use, they require expensive and technically complex equipment. Meeting a need for further development of assays for detection of BoNTs, researchers now have developed a nanopore-based assay for detection of BoNT-B.

White-light-emitting diodes have many advantages over forms of lighting - incandescent, fluorescent and halogen - and this solid-state lighting technique is bound to make major inroads into the commercial and household markets. Researchers have now designed precursors and chemical processes to synthesize intercrossed carbon nanomaterials with relatively pure hydroxy surface states for the first time, which enable them to overcome the aggregation-induced quenching (AIQ) effect, and to emit stable yellow-orange luminescence in both colloidal and solid states.

Electrochromic devices are some of the most attractive candidates for paper-like displays, so called electronic paper, which will be the next generation display. Researchers have now demonstrated solid state flexible polymer based electrochromic devices are fabricated continuously by stacking layers in one direction. This novel bottom-up approach with no need for a lamination step enables fully printed and 2D patterned organic electrochromics.
