Liquid-OLED Offers More Light-Emitting Possibilities.

Recently, researchers have fabricated a “liquid-OLED” – an OLED that uses a liquid organic semiconducting layer to transport charge.

The scientists, Denghui Xu and Chihaya Adachi from the Center for Future Chemistry at Kyushu University in Fukuoka, Japan, have reported the liquid-OLED in a recent issue of Applied Physics Letters. As they explain, the novel design is based on a liquid-emitting layer, and could have advantages for flexible displays and other organic electronics applications.

Usually, OLED displays use solid-state organic films that give off light when an electric current is applied. One significant benefit of OLED displays compared to traditional liquid crystal displays (LCDs) is that OLEDs do not require a backlight. For this reason, OLEDs can be made very thin and flexible, as well as use less power, enabling them to run longer on a single battery charge.

The new liquid-OLED could achieve these same benefits, but by using a liquid organic semiconductor instead of the solid-state films. Other than a few previous studies that have investigated using polymer solutions as the semiconducting layer, this is the first time that researchers have attempted to fabricate a practical liquid semiconductor for OLEDs.

Another survey looked at the ideal annual income Japanese women sought in a man; the most popular answers were “over $90,000” with 22.8%, and “over $70,000” again with 22.8%. 19.3% were seeking over an income of $130,000 or more.

BBC NEWS | Americas | Legal case against God dismissed.

A US judge has thrown out a case against God, ruling that because the defendant has no address, legal papers cannot be served.

He sought a permanent injunction to prevent the “death, destruction and terrorisation” caused by God.

“Given that this court finds that there can never be service effectuated on the named defendant this action will be dismissed with prejudice,” Judge Polk wrote in his ruling.

Mr Chambers sued God last year. He said God had threatened him and the people of Nebraska and had inflicted “widespread death, destruction and terrorisation of millions upon millions of the Earth’s inhabitants”.

The court, Mr Chambers said, had acknowledged the existence of God and “a consequence of that acknowledgement is a recognition of God’s omniscience”.

“Since God knows everything,” he reasoned, “God has notice of this lawsuit.”

BBC NEWS | Science & Environment | Single molecule’s stunning image.

The detailed chemical structure of a single molecule has been imaged for the first time, say researchers.

The physical shape of single carbon nanotubes has been outlined before, using similar techniques – but the new method even shows up chemical bonds.

Understanding structure on this scale could help in the design of many things on the molecular scale, particularly electronics or even drugs.

Technology Review: The Smallest Laser Ever Made.

Researchers have demonstrated the smallest laser ever, consisting of a nanoparticle just 44 nanometers across. The device is dubbed a “spaser” because it generates a form of radiation called surface plasmons. The technique allows light to be confined in very small spaces, and some physicists believe that spasers could form the basis of future optical computers just as transistors are the basis of today’s electronics.

BBC NEWS | Science & Environment | A step closer to ‘synthetic life’.

In what has been described as a step towards the creation of a synthetic cell, scientists have created a new “engineered” strain of bacteria.

A team successfully transferred the genome of one type of bacteria into a yeast cell, modified it, and then transplanted into another bacterium.

This paves the way to the creation of a synthetic organism – inserting a human-made genome into a bacterial cell.

DailyTech – Flexible LED Breakthrough Allows Bus-size Displays.

Reuters reports that researchers announced this week that they have devised a new way to make large-scale flexible displays that can be fitted to the contours of a bus, but are transparent. This would allow for video advertising on the displays, but passengers in the bus could still see out the windows.

DailyTech – Bionanoelectronic Devices Could Speed Up Electronics, Processing.

Mixing living cells with microscopic electronics may yield a new breed of processing power.

Though computer engineers and scientists have been repeatedly breaking speed barriers with new supercomputers, they still pale in comparison to the information processing power of complex biological systems. IBM’s Roadrunner supercomputer, presently the fastest in the world, has been used to mimic a single part of brain function, the visual cortex, and that’s only a fragment of the information the human body processes at any given moment.

So when researchers look to the future of computing, attempting to mimic bio-functions or combine them with electronics seems like a step in the right direction as far as speed and efficiency are concerned. However, the reality of the situation is not so supportive. Past attempts to merge the two types of systems have not yielded any special results.

Lawrence Livermore National Laboratory scientists are taking a deeper, or more nanoscopic, look into the idea of cohabitating the living and the inanimate. “With the creation of even smaller nanomaterials that are comparable to the size of biological molecules, we can integrate the systems at an even more localized level,” explains Aleksander Noy, lead LLNL scientist on the bio-electrical project.

DailyTech – IBM Using DNA to Create Semiconductors Below 22nm.

Microprocessors using DNA construction are ten years away

The breakthrough uses DNA, the building blocks of the human body, as the starting point for microprocessors built at under 22nm size. The semiconductor industry is facing significant hurdles in developing lithographic construction processes for under 22nm construction. Research is also being done into incorporating carbon nanotubes or silicon nanowires into construction processes.

The smaller a semiconductor can be built, the cheaper the parts are to produce as well because more can be made on a single wafer.

Researchers at IBM have made a breakthrough that involves using DNA molecules as a scaffolding to build semiconductors. The so-called DNA origami structures are compatible with lithographic processes used in construction today. The DNA scaffolding approach allows IBM to place millions of carbon nanotubes that self assemble precisely into patterns by sticking to the DNA molecules.

DailyTech – Organic Electronics Vastly Improved with New Breakthrough.

New breakthrough in organic electronics transports electrons and holes with one layer

The creation of organic circuits that could conduct holes and electrons before the team’s breakthrough required a complex design with two patterns on top of each other. One pattern transported holes and the other transported electrons.

The new process creates a circuit that is able to transport holes and electrons is very fast. Electrons moved five to eight times faster in the new circuit and it produced a voltage gain two to five times greater than previously seen in a polymer circuit.
