The work could lead to improvements in the energy density of lithium batteries that power electric vehicles.
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: Power
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
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: 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: Materials
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: Medical
MediSCAPE is a highspeed 3D microscope capable of capturing images of tissue structures that could guide surgeons to navigate tumors and their boundaries without needing to remove tissues and wait for pathology results.
Briefs: Materials
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: Design
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: Materials
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: Design
Have we found a better alternative to lithium-ion batteries?
Briefs: Electronics & Computers
The researchers plan to apply the design to edge computing devices.
Briefs: Robotics, Automation & Control
The technology could be useful in manufacturing and assembly plants for sorting packages, or in any environment where humans and robots collaborate.
Briefs: Robotics, Automation & Control
Interactive program aids motion planning for environments with obstacles.
Briefs: Robotics, Automation & Control
The piezoelectric “meta-bot” is capable of propulsion, movement, sensing, and decision-making.
Briefs: Imaging
Researchers built electroluminescent soft artificial muscles for flying, insect-scale robots.
Briefs: Robotics, Automation & Control
A new general-purpose optimizer can speed up the design of walking robots, self-driving vehicles, and other autonomous systems.
Briefs: Robotics, Automation & Control
The robots will be challenged to carry out work too dangerous for humans.
Briefs: Materials
Applications include a smart fabric for exoskeletons, an adaptive cast that adjusts its stiffness as an injury heals, or a deployable bridge that could be unrolled and stiffened.
Briefs: Electronics & Computers
A simple change to the surface of perovskite removes a barrier to its functionality.
Briefs: Energy
Additional applications include defogging/defrosting, wearable devices, industrial heat systems, sensors, thermochromic displays, and microfluidic chips.
Briefs: Power
The material remains effective as an energy harvester or sensor at temperatures to well above 572°F.
Briefs: Sensors/Data Acquisition
The process predicts when and where microscopic cracks will occur before they become catastrophic.
Briefs: Manned Systems
New design removes the need for mechanisms to perform active tilting of the wings or rotors, reducing system mass.
Briefs: Motion Control
Acoustic optimization for anti-phase asymmetric rotor.
Briefs: Motion Control
Gust load alleviation is an increasing concern for the design of fixed-wing aircraft with ultra-high aspect wings.
Briefs: Manned Systems
A lightweight alternative to rudders for aircraft with spanwise adaptive wings.
Briefs: Power
Advanced analyses shed light on the mechanism of a deadly problem plaguing combustion chambers in rocket engines.
