Power/Performance Bits: Jan. 23

Atomristors for thin memory Engineers at The University of Texas at Austin and Peking University developed a thin memory storage device with dense memory capacity. Dubbed "atomristors," the device enables 3-D integration of nanoscale memory with nanoscale transistors on the same chip. "For a long time, the consensus was that it wasn't possible to make memory devices from materials that were... » read more

Lithium-iron-oxide battery Scientists at Northwestern University and Argonne National Laboratory developed a rechargeable lithium-iron-oxide battery that can cycle more lithium ions than its common lithium-cobalt-oxide counterpart, leading to a much higher capacity. For their battery, the team not only replaced cobalt with iron, but forced oxygen to participate in the reaction process as we... » read more

World’s coldest chip Using a network of nuclear refrigerators, the University of Basel and others claim to have set the record for the world’s coldest chip. Researchers have cooled a chip to a temperature lower than 3 millikelvin. A millikelvin is one thousandth of a kelvin. Absolute zero is 0 kelvin or minus 273.15 °C. In the experiment, researchers used a chip that includes a Coulomb... » read more

Solar jet fuel Researchers at ETH Zurich demonstrated the ability to use solar energy to create the precursor to jet fuel from water and carbon dioxide, a process that could lead to carbon-neutral air travel. The scientists performed 295 consecutive cycles in a 4 kW solar reactor, yielding 700 standard liters of hydrogen and carbon monoxide (syngas), the precursor to kerosene and other liqu... » read more

Piezoelectric, ingestible sensors With an aim to help doctors diagnose gastrointestinal disorders that slow down the passage of food through the digestive tract, MIT and Brigham and Women’s Hospital researchers have built a flexible sensor that can be rolled up and swallowed. Once ingested, the sensor adheres to the stomach wall or intestinal lining, where it can measure the rhythmic con... » read more

Theoretical all-carbon circuits Engineers at the University of Texas at Dallas, the University of Illinois at Urbana-Champaign, the University of Central Florida, and Northwestern University designed a novel computing system made solely from carbon. "The concept brings together an assortment of existing nanoscale technologies and combines them in a new way," said Dr. Joseph S. Friedman, ass... » read more

Dental implants Borrowing some of the same processes used in the semiconductor industry, the Peninsula Schools of Medicine and Dentistry and the University of Plymouth have developed new nanocoating materials for dental implants. Some three million Americans have dental implants, according to the American Academy of Implant Dentistry (AAID). This number is rising by 500,000 a year, accordin... » read more

CMP replacement? For years, chipmakers have used chemical-mechanical-polishing (CMP) tools to smooth or polish the surface of a wafer. CMP works, but the technology is time-consuming and expensive. CMP can also leave unwanted residual patterns and defects near the surface. In response, Russia’s National Research Nuclear University MEPhI (Moscow Engineering Physics Institute) has help... » 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
