Scientists build circuit that generates clean, limitless power from graphene
Physicists from the University of Arkansas (UArk) have successfully developed a circuit capable of generating electricity from the natural thermal motion of graphene. “An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors,” said lead researchers Paul Thibado, a professor of physics and lead […]

Solar cell technology is being adapted to detect chemical warfare agents and pesticides
In what is a unique application of new green technology, Australian researchers have figured out how to adapt a component from solar cells to develop a light-based detection system for deadly toxins. According to them, the system they’ve designed can be used to detect the presence of chemical warfare agents and pesticides. While the former have been banned internationally […]

Gold-coated silver nanowires promise cheaper, more flexible smart glass
Scientists from the Institut National de la Recherche Scientifique (INRS) in Canada developed a new way to create foldable and solid devices using silver nanowires coated in gold. Solid and flexible electrochromic (EC) devices, such as foldable displays in smartphones, smart windows and wearable electronics traditionally use iridium tin oxide (ITO) electrodes. But despite their use in […]

Physicists build “energy harvesting” circuit from graphene
A team of physicists from the University of Arkansas (U of A) has successfully developed graphene-based circuits capable of providing nearly limitless power for small devices. Described in a paper published in the journal Physical Review E, the findings prove a theory the physicists developed at the U of A three yeas ago. This theory stated that freestanding graphene […]

Researchers develop a rewritable paper coating that encrypts sensitive data using only WATER
Chinese researchers have developed a special kind of paper coating that allows invisible messages to be written on it with water. The messages are visible only under ultraviolet (UV) light and can be erased by heating the paper. In a paper published in the journal Matter, the researchers described how invisible messages can be printed […]

Ammonia identified as a cost-effective material to store energy for fuel cells
On paper, fuel cells offer the best of both worlds. They can provide clean electric power for vehicles, without the need for long charging times that plague most EVs. The main problem with fuel cells, however, is that they use hydrogen, which is quite flammable and needs specialized infrastructure and equipment to handle. To address […]

Nanomaterials called metal-organic frameworks (MOFs) can give plants “super” abilities, reveals study
While much has been written about nanomaterials and the benefits they will give humans, not as much thought has been given to how they can benefit plants. A recent study looks to change that, exploring how nanomaterials may be able to give plants “super” abilities. The researchers, who presented their study at the American Chemical […]

Ancient secrets to fantastic hair: Scientists uncovered 3000 year old hair wax from the hair of Ancient Egyptian noblewomen
The Ancient Egyptians may have discovered the secret to having long-lasting, perfectly styled hair. Russian scientists identified a special kind of hair wax used by the Ancient Egyptians to preserve the shiny curls of their noblewomen for over 3,000 years. In a recent study published in the Journal of Analytical Chemistry, a team from Moscow’s Kurchatov Institute described the contents […]

Plants redirect electrons to an alternative route to prevent damage caused by oxidative stress
It may not seem like it, but plants can also experience stress – oxidative stress, that is – from absorbing too much light. Now, scientists are looking into the process by which plants manage oxidative stress. Researchers from Kobe University have recently released the results of a study that looked into how plants manage oxidative stress. The study focused […]

Researchers develop new chemical separation method that could pave the way for faster purification of elements, potential cancer treatment
Separating elements, especially some of the rarer ones used for certain medical treatments, can be a time-intensive and painstaking task. A recent study, however, promises a faster and more efficient method of separating elements – one that may help obtain a rare isotope that shows promise in cancer treatments. Researchers at the Department of Energy‘s […]
