Copolymer solution uses water-loving differential to induce desorption at lower temperatures

Foaming plastic carriers creates uneven surfaces, more area for necessary microorganisms

An international team of researchers has developed novel bio-degradable rigid foams derived from pineapple waste, showcasing impressive properties. Starch and cellulosic materials are key components of the foams, which are processed via microwave gel formation and filler blending. The foams feature high strength, and rapid biodegradation, with potential for practical use from packaging, to construction, automotive, and aerospace.

A new method for connecting neurons in neuromorphic wetware has been developed by researchers from Osaka University and Hokkaido University. The wetware comprises conductive polymer wires grown in a three-dimensional configuration, done by applying square-wave voltage to electrodes submerged in a precursor solution. The voltage can modify wire conductance, allowing the network to be trained. This fabricated network is able to perform unsupervised Hebbian learning and spike-based learning.

Researchers at The University of Tokyo develop a simple but effective method of bonding polymers with galvanized steel, a material ubiquitous in the automobile industry, to cheaply and easily create a lightweight and durable product.

A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has demonstrated that in the presence of polymers (preferably, polyionic liquids), crystals of various types grow in common solvents, at constant temperature, much bigger and much faster when stirred, rather than kept still.

A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has engineered the light-absorbing layer material with the new composition of perovskite material and applied it to the solar cell.
