Improved extraction efficiency by double‐soak, filtration‐extraction process

Journal of the American Oil Chemists' Society, 1961
AbstractA simple and inexpensive modification of the filtration extraction process has been described which permits improved extraction efficieney and reduced solvent requirements over that presently obtained. It comprises an additional soaking step, which can be readily incorporated.Bench‐scale data are presented on three different oil‐bearing ...

Sound transmission through double panel systems lined with soaked insulation materials

4th AIAA/CEAS Aeroacoustics Conference, 1998
The transmission loss of a double panel system enclosing a partially reticulated polyurethan foam wetted with different amounts of water according to prescribed climate treatments have been examined using a general linear modelling for sound dissipation in light isotropic homogeneous porous materials.

Dexmedetomidine-soaked nasal packing can reduce pain and improve sleep quality after nasal endoscopic surgery: a double-blind, randomized, controlled clinical trial

Sleep and Breathing, 2021
Bilateral endoscopic nasal surgery is usually associated with pain and sleep disturbance. The aim of this study was to evaluate the effects of dexmedetomidine-soaked nasal packing on analgesia and improvement of sleep quality in patients undergoing this surgery.Eighty patients were enrolled and randomly allocated into 4 groups.

Effects of local intraoperative epidural use of triamcinolone acetonide–soaked Gelfoam on postoperative outcomes in patients undergoing posterolateral lumbar spinal fusion surgery: a randomized, placebo-controlled, double-blind trial

Journal of Neurosurgery: Spine, 2022
OBJECTIVE Prior evidence has supported the use of local intraoperative epidural steroids in lumbar discectomy for improvements in postoperative pain and outcomes. However, currently there is a paucity of data regarding the efficacy of local epidural steroids in spinal fusion procedures.

Towards High Strength-Ductility Balance Using Double Annealing Cycles

Materials Science Forum, 2023
Impact of first annealing on the formation and evolution of the microstructure during second annealing and on the final mechanical properties was investigated. Simple Fe-C-Mn-Si steel was used in this study.

3D printing of a tough double-network hydrogel and its use as a scaffold to construct a tissue-like hydrogel composite.

Journal of materials chemistry. B, 2022
To mimic biological tissues with high toughness such as cartilage, it is highly desired to fabricate stable and tough hydrogels with intricate shapes to act as a structural support.

Chitosan-based double cross-linked ionic hydrogels as a strain and pressure sensor with broad strain-range and high sensitivity.

Journal of materials chemistry. B, 2022
A conductive hydrogel P(AAm-co-AA)/CS-Fe3+ with double cross-linked networks was fabricated using a one-step polymerization by UV irradiation and a soaking process in Fe(NO3)3 solution.

An extremely tough and ionic conductive natural-polymer-based double network hydrogel.

Journal of materials chemistry. B, 2021
Hydrogels are widely used in fields such as drug delivery, tissue regeneration, soft robotics and flexible smart electronic devices, yet their application is often limited by unsatisfactory mechanical behaviors.

Effect of double-soak sintering on magnetic properties of MgxMnyAlzFe3?(x+y+z)O4 ferrites

Journal of Materials Science, 1974
A study was made to determine the effects of a double-soak sintering process on the saturation magnetization, Curie temperature and hysteresis properties of an Al-substituted MgMn-microwave ferrite. This process decreases saturation magnetization and magnetic induction, while increasing the loop squareness and the Curie temperature.

One-Step Soaking Approach for the Development of High-Strength, Tough Silicone Hydrogels with Elevated Polysiloxane Content.

ACS Macro Letters
Silicone hydrogels (SiHys) present a variety of promising applications. However, their intrinsic mechanical limitations and low silicone content often restrict their practical use.
