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?
Growing functioning human neural networks in 3D from stem cells
A team of researchers has developed three-dimensional human tissue culture models for the central nervous system that mimic structural and functional features of the brain and demonstrate neural activity sustained over a period of many months.
First-ever coloured thin films of nanotubes created
Researchers present a technique to produce large quantities of pristine single-walled carbon nanotubes in select shades of the rainbow. The secret is a fine-tuned fabrication process—and a small dose of CO2.
Chemists synthesize narrow ribbons of graphene using light and heat
Silicon — the shiny, brittle metal commonly used to make semiconductors — is an essential ingredient of modern-day electronics. But as electronic devices have become smaller and smaller, creating tiny silicon components that fit inside them has become more challenging and more expensive.
SOFT e-textiles could offer advanced protection for soldiers
New technology that harnesses electronic signals in a smart fabric could lead to advanced hazardous-material gear that protects against toxic chemicals, according to research.
New fast-charging, high-energy electric-car battery technology
An international team of researchers has presented a novel hydrogen isotope separation system based on a porous metal organic framework.
A new miniature solution for storing renewable energy
Scientists have long searched for the next generation of materials that can catalyze a revolution in renewable energy harvesting and storage.
Efficient catalyst for key step in artificial photosynthesis
Chemists have designed a new catalyst that speeds up the rate of a key step in "artificial photosynthesis" -- an effort to mimic how plants, algae, and some bacteria harness sunlight to convert water and carbon dioxide into energy-rich fuels.
Solar paint offers endless energy from water vapour
Researchers have developed a solar paint that can absorb water vapour and split it to generate hydrogen - the cleanest source of energy.
Stabilising energy storage
Because the sun doesn't always shine, solar utilities need a way to store extra charge for a rainy day. The same goes for wind power facilities, since the wind doesn't always blow. To take full advantage of renewable energy, electrical grids need large batteries that can store the power coming from wind and solar installations until it is needed.
Wireless, wearable toxic-gas detector
Researchers have developed low-cost chemical sensors, made from chemically altered carbon nanotubes, that enable smartphones or other wireless devices to detect trace amounts of toxic gases.
Flipping a chemical switch helps perovskite solar cells beat the heat
Thin films of crystalline materials called perovskites provide a promising new way of making inexpensive and efficient solar cells. Now, an international team of researchers has shown a way of flipping a chemical switch that converts one type of perovskite into another — a type that has better thermal stability and is a better light absorber.
An alternative to platinum in fuel cells
Research teams have produced a cost-effective catalyst material for fuel cells using a new preparation process which they analysed in detail.
Nanotechnology device to simplify blood sugar testing
This innovation depends on an injectable, near-infrared optical biosensor nanotube that would read a person's blood glucose constantly and an optical glucose scanner that can access the data collected by nanotube.
Chemist aims to put his nanohoops into future devices
Nanohoops, can be made using both carbon and other atoms. Because they efficiently absorb and distribute energy, they may be useful in solar cells, organic light-emitting diodes or as new sensors or probes for medicine.
Discovery about new battery overturns decades of false assumptions
New findings have overturned a scientific dogma that stood for decades, by showing that potassium can work with graphite in a potassium-ion battery - a discovery that could pose a challenge and sustainable alternative to the widely-used lithium-ion battery.
Method for scaling up production of thin electronic material
Sheets of graphene and other materials that are virtually two-dimensional hold great promise for electronic, optical, and other high-tech applications. But the biggest limitation in unleashing this potential has been figuring out how to make these materials in the form of anything larger than tiny flakes.
World's first solar battery to performance milestone
After debuting the world's first solar air battery last fall, researchers at The Ohio State University have now reached a new milestone.
Researchers produce powerful biosensor for medical diagnostics
This new biosensor has demonstrated very high sensitivity in detecting cholera toxins and can provide earlier diagnosis of conditions such as cancer and other infectious diseases.
