System Bits: Sept.1


The quantum description of nature In quantum mechanics, the underlying physical rules that govern the fundamental behavior of matter and light at the atomic scale state that nothing can quite be completely at rest, but now for the first time, a team of researchers from Caltech, McGill University, and the Max Planck Institute for the Science of Light has found a way to observe—and control—t... » read more

Fundamental physics discovery The study of correlated electrons — a branch of fundamental physics research — focuses on interactions between the electrons in metals, which now are understood a bit better, according to Caltech researchers. Understanding these interactions and the unique properties they produce could lead to the development of novel materials and technologies, but they mu... » read more

Molecular chips Researchers from various organizations have devised a transistor consisting of a single molecule and a few atoms. The work could one day lead to the integration of molecular-based devices with existing semiconductor technologies. This work was conducted by Paul-Drude-Institut für Festkörperelektronik (PDI), Freie Universität Berlin (FUB), NTT and the U.S. Naval Research L... » read more

Faster lasers for better memory To visualize in four dimensions the changing atomic configurations of materials undergoing phase changes — which happens when data is recorded on DVDs and Blu-ray disks — Caltech researchers have adopted a novel technique called ultrafast electron crystallography (UEC) that uses ultrafast laser pulses that speed up the data recording process. Interestingl... » read more

Liquid metal for Terminator robots The Chinese Academy of Sciences and Tsinghua University have devised a robot-like, self-fueled liquid metal mollusk. The liquid metal alloy within the system can move by itself and change form like the shape-shifting T-1000 robot in the movie Terminator 2: Judgment Day. The system consists of a liquid metal motor. The liquid metal is a mix of gallium, i... » read more

Hybrid supercapacitors Researchers at UCLA combined the best qualities of batteries and supercapacitors in a new 3-D hybrid supercapacitor. Based on laser-scribed graphene and manganese dioxide, the new component stores large amounts of energy, recharges quickly and can last for more than 10,000 recharge cycles. The team also created a microsupercapacitor small enough to fit in wearable o... » read more

A better band-aid UC Berkeley engineers are working on a bandage that can detect bedsores before they are visible - while recovery from them is still possible. Leveraging flexible electronics advancements, the researchers collaborated with colleagues at UC San Francisco to create their “smart bandage” that uses electrical currents to detect early tissue damage from pressure ulcers as th... » read more

Artificial photosynthesis: leaves of nickel Inspired by a chemical process found in leaves, Caltech scientists developed an electrically conductive film that could help pave the way for devices capable of harnessing sunlight to split water into hydrogen fuel. When applied to semiconducting materials (it's been tested with silicon, indium phosphide, and cadmium telluride), the team's film ... » read more

Harvesting more of the sun's energy As solar panels become less expensive and capable of generating more power, solar energy is becoming a more commercially viable alternative source of electricity and today’s photovoltaic cells can only absorb and use a small fraction of that light, which means a significant amount of solar energy goes untapped. However, a new technology created by research... » read more

How transistors operate at absolute zero Research led by scientists at Chalmers University of Technology in Sweden and Caltech in California have demonstrated how noise in a microwave amplifier is limited by self-heating at very low temperatures, which is expected to be of importance for future discoveries in such as quantum computers and radio astronomy. The team also included researchers ... » read more
