Latest Tech Briefs

Briefs: Green Design & Manufacturing
Energy Storage Materials Make Batteries More Efficient and Heat-Resistant
In redox flow batteries, the energy-storing components are dissolved in a solvent and can be stored at a decentralized location.
Briefs: Electronics & Computers
Scientists have taken the first step to creating the next generation of wearable health monitors.
Briefs: Green Design & Manufacturing
A new way to unprint paper uses intense pulsed light from a xenon lamp.
Briefs: Robotics, Automation & Control
The ability to emit light also brings these microscale robots, which weigh barely more than a paper clip, one step closer to flying on their own outside the lab.
Briefs: Nanotechnology
Researchers from the Cockrell School of Engineering at The University of Texas at Austin recently created the first ever solid-state optical nanomotor.
Briefs: Green Design & Manufacturing
Researchers have developed an inexpensive and eco-friendly steam generator to desalinate and purify water using sunlight.
Briefs: Green Design & Manufacturing
Engineers at the U.S. Department of Energy’s Argonne National Laboratory have designed a novel building-solar controller that optimizes solar energy with smart technology to keep microgrids operating for up to five days.
Briefs: Energy
When it discharges, the carbon dioxide can be released in a controlled way and collected to be reused or disposed of responsibly.
Briefs: Energy
A new optimization framework created by researchers at University of Michigan could drastically reduce the cost of assessing how battery configurations will perform over the long haul.
Briefs: Energy
Inducing TR in a battery cell allows engineers to test and improve the safety performance of overheated batteries that can potentially catch fire or explode.
Briefs: Design
The system makes it possible to integrate data from prior experiments, and information based on personal observations by experienced workers, into the machine learning process.
Briefs: Energy
Lithium-ion batteries are currently the preferred technology for powering electric vehicles, but they’re too expensive for long-duration grid-scale energy storage systems.
Briefs: Design
A team of researchers at EMPA have developed a water-activated disposable paper battery.
Briefs: Energy
In batteries, electrolyte is the circulating “blood” that keeps the energy flowing. The electrolyte forms by dissolving salts in solvents, resulting in charged ions that flow between the positive and negative electrodes.
Briefs: Energy
The work could lead to improvements in the energy density of lithium batteries that power electric vehicles.
Briefs: Power
An experimental plant-based jet fuel could increase engine performance and efficiency, while dispensing with aromatics, the pollution-causing compounds found in conventional fuels.
Briefs: Energy
In tests, the proof-of-concept batteries retained 87.5 percent and 115.9 percent of their energy capacity at -40 °C and 50 °C (-40 °F and 122 °F), respectively.
Briefs: Energy
Over the course of their research, the team discovered that these anthraquinones decompose slowly over time, regardless of how many times the battery has been used.
Briefs: Lighting Technology
Tests showed the metalens they made could focus its 197-nanometer output onto a spot measuring 1.7 microns in diameter, increasing the power density of the light output by 21 times.
Briefs: Lighting Technology
Plasmonics is a technology that essentially traps the energy of light in groups of electrons oscillating together on a metal surface.
Briefs: Electronics & Computers
It achieves 40 channels by combining a frequency comb light source based on a new photonic crystal resonator developed by the National Institute of Standards and Technology (NIST) with an optimized mode-division multiplexer.
Briefs: Energy
Have we found a better alternative to lithium-ion batteries?
Briefs: Design
The researchers plan to apply the design to edge computing devices.
Briefs: Software
The technology could be useful in manufacturing and assembly plants for sorting packages, or in any environment where humans and robots collaborate.
Briefs: Imaging
Researchers built electroluminescent soft artificial muscles for flying, insect-scale robots.
Briefs: Electronics & Computers
A simple change to the surface of perovskite removes a barrier to its functionality.
Briefs: Medical
Additional applications include defogging/defrosting, wearable devices, industrial heat systems, sensors, thermochromic displays, and microfluidic chips.
Briefs: Materials
The material remains effective as an energy harvester or sensor at temperatures to well above 572°F.
Briefs: Aerospace
Advanced analyses shed light on the mechanism of a deadly problem plaguing combustion chambers in rocket engines.
