Chemical aspects of polymer recycling
Polymer recycling Chemical recycling Commodity polymers
2023/12/5
Since recycling of polymers is a preferred means of reducing unwanted wastes and land-filling activity, and recovering monomers or other materials of economic value, tertiary methods of recycling (che...
Epoxy vitrimer based on borate ester bond for green degradation, closed-loop recycling, and ready reprocessing
Green degradation Thermoset Dynamic covalent bond Recyclable
2023/12/1
The three-dimensional network of traditional epoxy resin endows it with suitable properties, but it also presents challenges in reprocessing and recycling. Recent years have witnessed the development ...
Japan's Federation of Electric Power Companies (FEPC) announced it will work with France's Orano on demonstration research and development for the reprocessing of used mixed oxide (MOX) fuel.
In 2019, MIT’s Environment, Health, and Safety (EHS) Office collaborated with several research labs in the Department of Biology to determine the feasibility of recycling clean lab plastics. Based on ...
The accumulation of plastic waste in the oceans, soil, and even in our bodies is one of the major pollution issues of modern times, with over 5 billion tons disposed of so far. Despite major efforts t...
Under the intensity of a prolonged pandemic, the world finds an ever-growing and seemingly never-ending waste stream of used surgical masks, plastic face shields, and medical gloves and gowns. Cornell...
A new study co-led by a Cornell researcher has identified serpentinite – a green rock that looks a bit like snakeskin and holds fluids in its mineral structures – as a key driver of the oxygen recycli...
Dissolvable smartwatch makes for easier electronics recycling
dissolvable smartwatch electronics recycling metal nanocomposites
2021/8/6
Small electronics, including smartwatches and fitness trackers, aren't easily dismantled and recycled. So when a new model comes out, most users send the old devices into hazardous waste streams. To s...
Study reports repair of mitochondrial recycling defect linked to Parkinson’s disease
dopamine PD mitochondria recovery
2021/8/11
A study in mice shows that an experimental small molecule helped restore the removal of damaged mitochondria from dopamine-producing brain cells.
Tossing worn-out solar panels into landfills may soon become electronics waste history.
Microbes far beneath the seafloor rely on carbon recycling to survive（图）
Microbes far beneath seafloor rely carbon recycling survive
2020/3/20
Scientists at the Woods Hole Oceanographic Institution have revealed how microorganisms survive in rocks nestled thousands of feet beneath the ocean floor in the lower oceanic crust. The study is publ...
Quantum Alice and Silent Bob: Qubit-based Quantum Key Recycling with almost no classical communication
quantum cryptography quantum key recycling
2019/8/2
We introduce a Quantum Key Recycling (QKR) protocol that needs no classical communication from Alice to Bob. Alice sends only a cipherstate, which consists of qubits that are individually measured by ...
Algae-killing viruses spur nutrient recycling in oceans（图）
Algae-killing viruses nutrient recycling oceans
2019/10/23
Scientists have confirmed that viruses can kill marine algae called diatoms, but diatom die-offs near the ocean surface may provide nutrients and organic matter for recycling by other algae.Diatoms ar...

Security proof for Quantum Key Recycling with noise
quantum cryptography quantum key recycling
2018/3/13
Quantum Key Recycling aims to re-use the keys employed in quantum encryption and quantum authentication schemes. We consider QKR protocols where classical information is embedded in qubit states. A pa...
