Published Chemists tackle the tough challenge of recycling mixed plastics
(via sciencedaily.com)
Original source 
Polymer chemists have been finding ways to tackle the environmental problems humans have created with plastics waste. Now, a team has come up with fundamental new chemistry that seeds a creative solution to the challenge of recycling mixed-use plastics.
Published Tunneling electrons
(via sciencedaily.com)
Original source 
By superimposing two laser fields of different strengths and frequency, the electron emission of metals can be measured and controlled precisely to a few attoseconds. Physicists have shown that this is the case. The findings could lead to new quantum-mechanical insights and enable electronic circuits that are a million times faster than today.
Published New chemistry can extract virgin-grade materials from wind turbine blades in one process
(via sciencedaily.com)
Original source 
Researchers have developed a chemical process that can disassemble the epoxy composite of wind turbine blades and simultaneously extract intact glass fibers as well as one of the epoxy resin's original building blocks in a high quality. The recovered materials could potentially be used in the production of new blades.
Published How a horse whisperer can help engineers build better robots
(via sciencedaily.com)
Original source 
New research shows us that age-old interactions between people and their horses can teach us something about building robots designed to improve our lives.
Published CO2 recycling: What is the role of the electrolyte?
(via sciencedaily.com)
Original source 
The greenhouse gas carbon dioxide can be converted into useful hydrocarbons by electrolysis. The design of the electrolysis cell is crucial in this process. The so-called zero-gap cell is particularly suitable for industrial processes. But there are still problems: The cathodes clog up quickly.
Published Jellyfish-like robots could one day clean up the world's oceans
(via sciencedaily.com)
Original source 
Roboticists have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling safe interactions in delicate environments such as coral reefs. Jellyfish-Bot could become an important tool for environmental remediation.
Published Researchers team up with national lab for innovative look at copper reactions
(via sciencedaily.com)
Original source 
Researchers are working to get a better look at how peroxides on the surface of copper oxide promote the oxidation of hydrogen but inhibit the oxidation of carbon monoxide, allowing them to steer oxidation reactions.
Published Cheaper method for making woven displays and smart fabrics -- of any size or shape
(via sciencedaily.com)
Original source 
Researchers have developed next-generation smart textiles -- incorporating LEDs, sensors, energy harvesting, and storage -- that can be produced inexpensively, in any shape or size, using the same machines used to make the clothing we wear every day.
Published Nanowire networks learn and remember like a human brain
(via sciencedaily.com)
Original source 
Scientists have demonstrated nanowire networks can exhibit both short- and long-term memory like the human brain.
Published Greener batteries
(via sciencedaily.com)
Original source 
Our modern rechargeable batteries, such as lithium-ion batteries, are anything but sustainable. One alternative is organic batteries with redox-organic electrode materials (OEMs), which can be synthesized from natural 'green' materials. A team has now introduced a new OEM for aqueous organic high-capacity batteries that can be easily and cheaply recycled.
Published Synthetic biology meets fashion in engineered silk
(via sciencedaily.com)
Original source 
Engineers developed a method to create synthetic spider silk at high yields while retaining strength and toughness using mussel foot proteins.
Published ChatGPT is still no match for humans when it comes to accounting
(via sciencedaily.com)
Original source 
ChatGPT faced off against students on accounting assessments. Students scored an overall average of 76.7%, compared to ChatGPT's score of 47.4%. On a 11.3% of questions, ChatGPT scored higher than the student average, doing particularly well on AIS and auditing. But the AI bot did worse on tax, financial, and managerial assessments, possibly because ChatGPT struggled with the mathematical processes required for the latter type.
Published AI system can generate novel proteins that meet structural design targets
(via sciencedaily.com)
Original source 
A new machine-learning system can generate protein designs with certain structural features, and which do not exist in nature. These proteins could be utilized to make materials that have similar mechanical properties to existing materials, like polymers, but which would have a much smaller carbon footprint.
Published Quantum entanglement could make accelerometers and dark matter sensors more accurate
(via sciencedaily.com)
Original source 
The 'spooky action at a distance' that once unnerved Einstein may be on its way to being as pedestrian as the gyroscopes that currently measure acceleration in smartphones.
Published Quantum computer applied to chemistry
(via sciencedaily.com)
Original source 
There are high expectations that quantum computers may deliver revolutionary new possibilities for simulating chemical processes. This could have a major impact on everything from the development of new pharmaceuticals to new materials. Researchers have now used a quantum computer to undertake calculations within a real-life case in chemistry.
Published Nanoparticles provoke immune response against tumors but avoid side effects
(via sciencedaily.com)
Original source 
Researchers find that when immunostimulatory drugs called imidazoquinolines are delivered using specialized bottlebrush nanoparticles, the drugs provoke the immune system to attack tumors while eliminating the side effects that occur when the drugs are given on their own.
Published New findings pave the way for stable organic solar cells that may enable cheap and renewable electricity generation
(via sciencedaily.com)
Original source 
Organic solar cells show great promise for clean energy applications. However, photovoltaic modules made from organic semiconductors do not maintain their efficiency for long enough under sunlight for real world applications. Scientists have now revealed an important reason why organic solar cells rapidly degrade under operation. This new insight will drive the design of more stale materials for organic semiconductor-based photovoltaics, thus enabling cheap and renewable electricity generation.
