Mimicking roses for solar Scientists from the Karlsruhe Institute of Technology (KIT) and the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) reproduced the epidermal cells of rose petals and integrated the transparent replicas into an organic solar cell, with an efficiency gain of 12%. The epidermis of rose petals consists of a disorganized arrangement of densely p... » read more

A chip with 1,000 processors A microchip containing 1,000 independent programmable processors has been designed by a team at the University of California, Davis. Called the KiloCore chip, it contains 621 million transistors and was fabricated by IBM using its 32nm CMOS technology. Cores operate at an average maximum clock frequency of 1.78 GHz, and they transfer data directly to each other r... » read more

Origami battery A new disposable battery that folds like an origami ninja star could power biosensors and other small devices for use in challenging field conditions. The researchers, from Binghamton University, previously developed a paper-based origami battery. The first design, shaped like a matchbook, stacked four modules together. The ninja star version, which measures about 2.5 inches ... » read more

Tiny lasers on silicon A group of scientists from Hong Kong University of Science and Technology, the University of California, Santa Barbara, Sandia National Laboratories, and Harvard University were able to fabricate tiny lasers directly on silicon. To do this, they first had to resolve silicon crystal lattice defects to a point where the cavities were essentially equivalent to those gr... » read more

Solar thermophotovoltaics A team of MIT researchers demonstrated a device based on a method that enables solar cells to break through a theoretically predicted ceiling on how much sunlight they can convert into electricity. Since 1961 it has been known that there is an absolute theoretical limit, called the Shockley-Queisser Limit, to how efficient traditional solar cells can be in their ... » read more

Reducing MRAM chip area Researchers from Tohoku University developed a technology to stack magnetic tunnel junctions (MTJ) directly on the via without causing deterioration to its electric/magnetic characteristics. The team focused on reducing the memory cell area of spin-transfer torque magnetic random access memory (STT-MRAM) in order to lower manufacturing costs, making them more compe... » read more

Shrinking perovskites Researchers from Imperial College London, Oxford University, Diamond Light Source, Pohang University of Science and Technology in Korea, and Rutgers University have discovered a material that can be chemically tailored to either expand or contract in a precise way and over a wide temperature range. This could lead to new composite materials that do not expand when heate... » read more

Non-toxic thin-films A team at Australia's University of New South Wales achieved the world's highest efficiency using flexible solar cells that are non-toxic and cheap to make, with a record 7.6% efficiency in a 1cm2 area thin-film CZTS cell. Unlike its thin-film competitors, CZTS cells are made from abundant materials: copper, zinc, tin and sulphur, and has none of the toxicity problems... » read more

Nanowire batteries University of California, Irvine researchers invented a nanowire-based battery material that can be recharged hundreds of thousands of times. Nanowires have long been sought as a battery material. However, these filaments are extremely fragile and don't hold up well to repeated discharging and recharging, or cycling. In a typical lithium-ion battery, they expand and gro... » read more

An on-chip light source Researchers at the Karlsruhe Institute of Technology (KIT) demonstrated that carbon nanotubes are suited for use as an on-chip light source. By integrating tiny carbon nanotubes into a nanostructured waveguide, the team developed a compact miniaturized switching element that converts electric signals into clearly defined optical signals. "The nanostructures act lik... » read more
