New technique could brighten screens, make smartphone batteries last
Our future TV and smartphone screens could have double the energy efficiency, thanks to a technique invented by scientists.
Organic solar cells will last 10 years in space
Over the past two decades, organic solar cells have garnered much attention thanks to their light weight, flexibility and unprecedented energy-to-weight ratios of 10 to 20 W/g, which make them a promising candidate for space applications, although their radiation stability is still poorly
Self-healing DNA nanostructures
DNA assembled into nanostructures such as tubes and origami-inspired shapes could someday find applications ranging from DNA computers to nanomedicine.
Flexible generators turn movement into energy
Wearable devices that harvest energy from movement are not a new idea, but a material created at Rice University may make them more practical.
Octopus-inspired wearable sensor
Wearable electronics that adhere to skin are an emerging trend in health sensor technology for their ability to monitor a variety of human activities, from heart rate to step count. But finding the best way to stick a device to the body has been a challenge.
3D-printed device detects biomarkers of preterm birth
Preterm birth is the leading complication of pregnancy. If doctors had a simple, accurate and inexpensive way to identify women at risk for the condition, they could develop better prevention strategies.
Safer electrochromic inks
Anyone who has a rear-view mirror that automatically dims blue in reaction to annoying high-beam headlights glaring from behind has seen an electrochromic film in action. Chemists have developed a new method to more safely and, by extension, easily produce these shear films, which change their color with the help of a tiny electric current. This could make them available to many industries that have not been able to feasibly use them before.
Using DNA templates to harness the sun's energy
As the world struggles to meet the increasing demand for energy, coupled with the rising levels of CO2 in the atmosphere from deforestation and the use of fossil fuels, photosynthesis in nature simply cannot keep up with the carbon cycle. But what if we could help the natural carbon cycle by learning from photosynthesis to generate our own sources of energy that didn't generate CO2?
Emberion are a start-up established in 2016, which spun-out from Nokia (Finland) and specialise in nanomaterial photodetector technologies.
Biosensor 'bandage' collects and analyzes sweat
Like other biofluids, sweat contains a wealth of information about what's going on inside the body. However, collecting the fluid for analysis, usually by dripping or absorbing it from the skin's surface, can be time-consuming and messy. Now, researchers have developed a bandage-like biosensor that both collects and -- in conjunction with a smart phone -- analyzes sweat.
New protein for gene editing may improve disease treatment
Researchers have developed a new technology that could change how gene editing is approached in the future. T
First scalable graphene yarns for wearable textiles produced
A team of researchers have developed a method to produce scalable graphene-based yarn. Multi-functional wearable e-textiles have been a focus of much attention due to their great potential for healthcare, sportswear, fitness and aerospace applications. Graphene has been considered a potentially good material for these types of applications due to its high conductivity, and flexibility.
Harnessing light for a solar-powered chemical industry
New technology that harnesses sunlight to drive chemical reactions is paving the way for a more sustainable chemical manufacturing industry, one of the globe's biggest energy users.
3D printed sponge to minimise effects of cancer treatment
With the help of sponges inserted in the bloodstream to absorb excess drugs, doctors are hoping to prevent the dangerous side effects of toxic chemotherapy agents or even deliver higher doses to knock back tumors, like liver cancer, that don't respond to more benign treatments.
Shape-conformable batteries based on 3D-printing technology
Flexible, wireless electronic devices are rapidly emerging and have reached the level of commercialization; nevertheless, most of battery shapes are limited to either spherical and/or rectangular structures, which results in inefficient space use.
