Sealing properties and structure optimization of packer rubber under high pressure and high temperature

Petroleum Science, 2019
During hydraulic fracturing operations of low-permeability reservoirs, packers are the key component to ensure the success of multistage fracturing. Packers enable sections of the wellbore to be sealed off and separately fractured by hydraulic pressure ...

Recycling Waste Rubber Into Single‐Walled Carbon Nanotubes: Narrow Chirality Distribution and Hydrogen Byproduct

Carbon Neutralization, Volume 4, Issue 5, September 2025.
A magnesia‐supported cobalt catalyst is designed to effectively upcycle waste rubbers and tires, producing high‐quality single‐walled carbon nanotubes with a narrow chirality distribution and hydrogen. This approach is applicable to six different types of rubber products and real‐world tires, offering a new pathway for waste rubber recycling and ...

Effect of two-phase crosslinking network on properties of acrylate rubber/hydrogenated nitrile rubber vulcanizates

Hecheng xiangjiao gongye
The two-phase crosslinking network state of acrylate rubber(ACM)/hydrogenated nitrile rubber (HNBR) vulcanizates was regulated by adjusting the amount of TRA using trithiocyanuric acid (TCY)/tetrasulfide bispentamethylene thiuram (TRA) as vulcanization ...

Poly(Alkylene Ether)s With Nitrile Pendent Groups

Journal of Polymer Science, Volume 63, Issue 13, Page 2745-2756, 1 July 2025.
Oxirane monomers were synthesized and polymerized using the Vanderberg initiator to obtain poly(alkylene ether) nitrile polymers. These polymers have a range of thermal properties and stabilities, providing potential alternatives to nitrile butadiene rubber (NBR) and hydrogenated NBR (HNBR).

Thermal aging behavior and lifetime prediction of industrial elastomeric compounds based on styrene–butadiene rubber

Polymer Engineering &Science, Volume 65, Issue 6, Page 3226-3246, June 2025.
Lifetime prediction of industrial elastomeric compounds. Abstract This work describes the thermal aging behavior of three industrial elastomeric compounds based on styrene–butadiene rubber (SBR) reinforced with carbon black. Samples were exposed to thermo‐oxidative aging at temperatures ranging from 70 to 120°C for durations between 14 and 365 days ...

Application of Electrochemical Impedance Spectroscopy for Diagnostics in Fuel Cells, Electrolyzers, and Batteries

ChemElectroChem, Volume 12, Issue 11, May 30, 2025.
Electrochemical impedance spectroscopy (EIS) is a powerful tool for understanding electrochemical reactions in energy conversion systems, such as fuel cells, electrolyzers, and batteries. It is also effective for diagnosing degradation rates and estimating remaining lifetimes through nondestructive analysis.

Toward Higher Energy Density All‐Solid‐State Batteries by Production of Freestanding Thin Solid Sulfidic Electrolyte Membranes in a Roll‐to‐Roll Process

Advanced Energy Materials, Volume 15, Issue 19, May 20, 2025.
The scalable production of a thin, but mechanically stable, and still flexible argyrodite solid electrolyte membrane is presented. It is fabricated and laminated onto a supporting non‐woven fabric in a concerted step using a continuous, industrially relevant, solvent‐free, roll‐to‐roll process. With this approach, a promising energy density of 670 Wh L−
