Published Robotic grippers offer unprecedented combo of strength and delicacy
(via sciencedaily.com) New robotic grippers are flexible enough to handle soft and fragile objects as well as heavier ones.
Published Faster thin film devices for energy storage and electronics
(via sciencedaily.com) An international research team reported the first realization of single-crystalline T-Nb2O5 thin films having two-dimensional (2D) vertical ionic transport channels, which results in a fast and colossal insulator-metal transition via Li ion intercalation through the 2D channels.
Published Thermal imaging innovation allows AI to see through pitch darkness like broad daylight
(via sciencedaily.com) Engineers have developed HADAR, or heat-assisted detection and ranging.
Published Cracking in lithium-ion batteries speeds up electric vehicle charging
(via sciencedaily.com) Rather than being solely detrimental, cracks in the positive electrode of lithium-ion batteries reduce battery charge time, research shows. This runs counter to the view of many electric vehicle manufacturers, who try to minimize cracking because it decreases battery longevity.
Published Energy-storing supercapacitor from cement, water, black carbon
(via sciencedaily.com) Engineers have created a 'supercapacitor' made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.
Published Scientists create novel approach to control energy waves in 4D
(via sciencedaily.com) Everyday life involves the three dimensions or 3D -- along an X, Y and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists have explored a 'fourth dimension' (4D), or synthetic dimension, as an extension of our current physical reality.
Published 3D display could soon bring touch to the digital world
(via sciencedaily.com) Engineers have designed a new, shape-shifting display that can fit on a card table and allows users to draw 3D designs and more.
Published Reinforcement learning allows underwater robots to locate and track objects underwater
(via sciencedaily.com) A team has shown that reinforcement learning -i.e., a neural network that learns the best action to perform at each moment based on a series of rewards- allows autonomous vehicles and underwater robots to locate and carefully track marine objects and animals.
Published This 3D printed gripper doesn't need electronics to function
(via sciencedaily.com) This soft robotic gripper is not only 3D printed in one print, it also doesn't need any electronics to work.
Published Researchers develop low-cost sensor to enhance robots' sense of touch
(via sciencedaily.com) Researchers have developed an L3 F-TOUCH sensor to enhance tactile capabilities in robots, allowing it to 'feel' objects and adjust its grip accordingly.
Published A simpler method for learning to control a robot
(via sciencedaily.com) A new machine-learning technique can efficiently learn to control a robot, leading to better performance with fewer data.
Published Robotic hand rotates objects using touch, not vision
(via sciencedaily.com) Inspired by the effortless way humans handle objects without seeing them, engineers have developed a new approach that enables a robotic hand to rotate objects solely through touch, without relying on vision.
Published A butterfly's first flight inspires a new way to produce force and electricity
(via sciencedaily.com) Original source Researchers have uncovered the promising capability of chitin as a sustainable smart biomaterial. Through water exchange with the environment, humidity-responsive chitinous films can generate mechanical and electrical energy for potential use in engineering and biomedical applications.
Published 'Quantum avalanche' explains how nonconductors turn into conductors
(via sciencedaily.com) Original source The study takes a new approach to answer a long-standing mystery about insulator-to-metal transitions.
Published Robot preachers get less respect, fewer donations
(via sciencedaily.com) As artificial intelligence expands across more professions, robot preachers and AI programs offer new means of sharing religious beliefs, but they may undermine credibility and reduce donations for religious groups that rely on them.
Published Renewable solar energy can help purify water, the environment
(via sciencedaily.com) Chemists have demonstrated that water remediation can be powered in part -- and perhaps even exclusively -- by renewable energy sources.
Published Device makes hydrogen from sunlight with record efficiency
(via sciencedaily.com) Engineers have created a device that turns sunlight into hydrogen with record-breaking efficiency by integrating next-generation halide perovskite semiconductors with electrocatalysts in a single, durable, cost-effective and scalable device.
Published Aluminum materials show promising performance for safer, cheaper, more powerful batteries
(via sciencedaily.com) Researchers are using aluminum foil to create batteries with higher energy density and greater stability. The team's new battery system could enable electric vehicles to run longer on a single charge and would be cheaper to manufacture -- all while having a positive impact on the environment.
Published Allowing robots to explore on their own
(via sciencedaily.com) Scientists have developed a suite of robotic systems and planners enabling robots to explore more quickly, probe the darkest corners of unknown environments, and create more accurate and detailed maps. The systems allow robots to do all this autonomously, finding their way and creating a map without human intervention.
Published Researchers put a new twist on graphite
(via sciencedaily.com) Original source Researchers report that it is possible to imbue graphite -- the bulk, 3D material found in No. 2 pencils -- with physical properties similar to graphite's 2D counterpart, graphene. Not only was this breakthrough unexpected, the team also believes its approach could be used to test whether similar types of bulk materials can also take on 2D-like properties. If so, 2D sheets won't be the only source for scientists to fuel technological revolutions. Bulk, 3D materials could be just as useful.
