CHEMICAL STUDIES ON THE DISPERSING AGENTS OF FIBERS (I)

Sen'i Gakkaishi, 1962
Poly (ethyl acrylate) of which molecular weight is about 100, 000 was hydrolyzed to controlled degrees with potassium hydroxide to produce compounds containing 70%, 80% and 90% carboxylate groups. Using these three water-soluble polymers as dispersing agents, sedimentation of pulp fibers in aqueous solution was investigated.At the more than about 0.016%

Conductive Additives for Next‐Generation Batteries: Emphasizing the Potential of Bio‐Derived 3D Carbon Architectures at Electrode–Electrolyte Interfaces

Advanced Materials Interfaces, EarlyView.
3D conductive frameworks can maintain continuous electron transport, mechanical stability, and interfacial integrity, helping next‐generation batteries operate more efficiently. This Review examines their relevance to Si anodes, all‐solid‐state batteries, and dry‐processed electrodes, and highlights bio‐derived carbons as sustainable, structurally ...

A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

Advanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

Stress response of the black coral Leiopathes glaberrima when exposed to sub-lethal amounts of crude oil and dispersant

Elementa: Science of the Anthropocene, 2017
The 2010 Deep Water Horizon oil well failure released billions of gallons of crude oil into the deep Gulf of Mexico, and, combined with chemical dispersants, this oil caused significant coral mortality.

The effect of chemical dispersant of the third generation (Finasol OSR 62) on the microbial biodegradation process of Zarzaitine oil in water treatment

Applied Water Science, 2022
The application of chemical dispersants aims to stimulate microbial oil degradation by increasing the bioavailability of oil compounds. Overall, nine microcosms were prepared (three for each treatment) using treated sediment with (i) dispersant (d: 25 ...

Impact of Physically and Chemically Dispersed Crude Oil on the Antioxidant Defense Capacities and Non-Specific Immune Responses in Sea Cucumber (Apostichopus japonicus)

Journal of Marine Science and Engineering, 2022
Currently, oil spill pollution is one of the major environmental concerns for sea cucumber (Apostichopus japonicus) aquaculture. During oil spills, spraying chemical dispersants is generally considered an efficient oil spill response. However, the impact

Dispersion Corrections Essential for the Study of Chemical Reactivity in Fullerenes

The Journal of Physical Chemistry A, 2011
In a previous paper (J. Phys. Chem. A2009, 113, 9721), we analyzed theoretically the Diels-Alder cycloaddition between cyclopentadiene and C(60) for which experimental results on energy barriers and reaction energies are known. One of the main conclusions reached was that the two-layered ONIOM2(B3LYP/6-31G(d):SVWN/STO-3G) method provides results very ...
