Power/Performance Bits: May 17


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

Diamond polarimeters The Thomas Jefferson National Accelerator Facility (Jefferson Lab) has achieved what it says are the highest precision measurements of polarization in an atom smasher. The measurements were conducted with an instrument called a Hall C Compton Polarimeter. The polarimeter makes use of electron-photon scattering techniques and diamond-based microstrip detectors. The g... » 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

DNA thermometers The University of Montreal has taken DNA and built the world’s smallest thermometer. The programmable DNA thermometer is 5nm, or 20,000 times smaller than a human hair. Applications for the technology include cell imaging, nanofluidics, nanomedicine, nanoelectronics and synthetic biology, according to the University of Montreal. Researchers added optical reporters to D... » read more

Neural network synapses In a development that could potentially be used as a basis for the hardware implementation of artificial neural networks, Moscow Institute of Physics and Technology (MIPT) researchers have created prototypes of electronic synapses based on ultra-thin films of hafnium oxide (HfO2). The team made the HfO2-based memristors measuring just 40x40 nm2, which exhibit propert... » 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

Multi-beam inspection For some time, Singaporean startup Maglen has been developing a multi-beam e-beam inspection tool technology. Now, Maglen has reached two milestones. First, it has devised a full column test stand. The test stand includes a mechanical column and software. The second milestone is also significant. “We also dropped our beam and obtained our very first images,” sai... » read more

Reconfigured Tesla coil electrifies materials In a development that could set a clear path toward scalable assembly of nanotubes from the bottom up, Rice University researchers have discovered that the strong force field emitted by a Tesla coil causes carbon nanotubes to self-assemble into long wires, a phenomenon they call Teslaphoresis. Rice chemist Paul Cherukuri led the team that develo... » 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
