Researchers from Monash University have taken another step towards the holy grail of renewable energy: the ability to store it cheaply. The team have created a new lithium-sulfur battery interlayer that promotes exceptionally fast lithium transfer, also improving the performance and lifetime of the batteries.
Industrial processes often separate compounds from each other and out of solution using energy-intensive thermal separation, which involves multiple evaporation and condensation cycles. More recently, energy-efficient nanofiltration membranes have emerged as a sustainable alternative. But even these have their downside: fossil-based polymers and toxic chemicals are needed to make them.
In a recent editorial article published in the journal Frontiers in Energy Research, researchers presented the framework of a circular economy based on biofuels and bioproducts.
Scientists based in Brazil and Portugal have developed an environmentally sustainable process to produce biodegradable plastic using pigment extracted from yeast by "green" solvents. In an article published in the journal Green Chemistry, they show that this biodegradable plastic could in future be used in smart packaging with antioxidant and anti-microbial properties.
A team of scientists headed by Dr Chang Su Kim from the Department of Nano-Bio Convergence of the Korea Institute of Materials Science (KIMS) successfully developed a material that offers antibacterial/antiviral properties without altering the physical properties of different products used commonly.
Manufacturing biopolymers from agricultural and industrial wastes are a growing area of research in materials sciences.
With the early evaluation of recently formulated sustainable products and chemicals, there is a possibility to evaluate the possible risk of hazardous substances being released in product cascades at a later point. This has been demonstrated in a proof-of-concept study coordinated together by Goethe University Frankfurt and RWTH Aachen University.
Palm tree waste represents one of the most commonly encountered forms of agricultural waste. It is a crucial concern for palm oil and related industries, especially in areas where oil palms are cultivated.
Using waste oil to produce biodiesel has been proposed as an alternative to burning greenhouse gas-emitting fossil fuels in several world economies.
Sea pineapples, an edible ascidian, are a Japanese delicacy. The region of Tohoku is well-known for its sea pineapple production—called hoya in Japanese.
