Researchers developed a method of transferring an energy source to virtually any shape using direct laser writing…
As electronics shrink in size, their energy sources have to fit into tighter, and sometimes more oddly-shaped, spaces. Researchers at the University of Missouri had this challenge in mind when they developed a method of transferring an energy source to virtually any shape using direct laser writing (DLW).

China has always been a frontrunner, especially in technological advancements. The country has engaged itself in increasingly audacious and ambitious projects. It is, therefore, no astonishment in calling China, ‘the rising power’.China has established Weather Modification Offices, that enables in manipulating weather using technology. The offices are a network of dedicated units that help in changing the weather throughout China. 55 billion tons of rain is created by China every year, making the country the largest cloud seeder on earth.
China has found the urge to manipulate weather mainly because of the extreme climate it experiences. The region has heavy downpour in rainy season while it suffers from drought in summers. Dust and sand storms are common in springtime. Moreover, given the fact that China has the largest population, it cannot afford to rely on climate. Most importantly, for agriculture. China found the only hope in technology in the manipulating weather for accruing benefits.
Weather modification offices require huge financial resources, human capital and weaponry. It is no wonder that China has spent millions of money on weather modification process. It has spent $150 million on single regional artificial rain program. China has escaped $10.4 billion dollars economic losses by employing weather modification system from 2002 to 2012. Over 35000 people have been employed to carry out this project. About 12000 rocket launchers are being used to fire pellets containing silver iodide into the clouds.

A future of soft robots that wash your dishes or smart T-shirts that power your cell phone may depend on the development of stretchy power sources. But traditional batteries are thick and rigid—not ideal properties for materials that would be used in tiny malleable devices. In a step toward wearable electronics, a team of researchers has produced a stretchy micro-supercapacitor using ribbons of graphene.
The researchers will present their work today at the 252nd National Meeting & Exposition of the American Chemical Society (ACS).
“Most power sources, such as phone batteries, are not stretchable. They are very rigid,” says Xiaodong Chen, Ph.D. “My team has made stretchable electrodes, and we have integrated them into a supercapacitor, which is an energy storage device that powers electronic gadgets.”

Additional insights on methods in improving efficiencies during the conversion of light energy into chemical energy.
The chromatophore of purple bacteria is an intracellular spherical vesicle that exists in numerous copies in the cell and that efficiently converts sunlight into ATP synthesis, operating typically under low light conditions. Building on an atomic-level structural model of a low-light-adapted chromatophore vesicle from Rhodobacter sphaeroides, we investigate the cooperation between more than a hundred protein complexes in the vesicle. The steady-state ATP production rate as a function of incident light intensity is determined after identifying quinol turnover at the cytochrome bc1 complex (cytbc1) as rate limiting and assuming that the quinone/quinol pool of about 900 molecules acts in a quasi-stationary state.

Every year, humans advance climate change and global warming — and quite likely our own eventual extinction — by injecting about 30 billion tonnes of carbon dioxide into the atmosphere.
A team of scientists from the University of Toronto (U of T) believes they’ve found a way to convert all these emissions into energy-rich fuel in a carbon-neutral cycle that uses a very abundant natural resource: silicon. Silicon, readily available in sand, is the seventh most-abundant element in the universe and the second most-abundant element in the earth’s crust.
The idea of converting carbon dioxide emissions to energy isn’t new: there’s been a global race to discover a material that can efficiently convert sunlight, carbon dioxide and water or hydrogen to fuel for decades. However, the chemical stability of carbon dioxide has made it difficult to find a practical solution.

A rubbery little “octobot” is the first robot made completely from soft parts, according to a new study. The tiny, squishy guy also doesn’t need batteries or wires of any kind, and runs on a liquid fuel.
The octopus-like robot is made of silicone rubber, and measures about 2.5 inches (6.5 centimeters) wide and long. The researchers say soft robots can adapt more easily to some environments than rigid machines, and this research could lead to autonomous robots that can sense their surroundings and interact with people.
Conventional robots are typically made from rigid parts, which makes them vulnerable to harm from bumps, scrapes, twists and falls. These hard parts can also hinder them from being able to squirm past obstacles. Increasingly, scientists are building robots made of soft, elastic plastic and rubber, designs inspired by octopuses, starfish and worms. These soft robots are generally more resistant to damage, and can wriggle past many of the obstacles that impair hard robots. [The 6 Strangest Robots Ever Created].

A novel device architecture is used to simultaneously achieve extremely high internal quantum efficiencies, low drive voltages, and long lifetimes, at practical luminance levels.
An LED with an emissive organic thin film sandwiched between the anode and cathode is known as an organic-LED (OLED). The emission mechanism of an OLED is superficially similar to that of a standard LED, i.e., holes and electrons are injected from the anode and cathode, respectively, and these carriers recombine to form excited states (excitons) that lead to light emission.1 In recent years, smartphones and TVs with OLED displays have rapidly become widespread because OLEDs provide high contrast, a wide color gamut, light weight, thinness, and flexibility for the displays. OLEDs also have great potential for the creation of new lighting applications.2 The high power consumption and short lifetime of OLEDs, however, remain key issues.
