Studies on the Detergency of Nonionic Surfactant. V.

open access: yesJournal of Japan Oil Chemists' Society, 1963
To investigate the detergency of nonionic surfactant, following two parts of experiments were carried out for the polyoxyethylene nonylphenyl ether EO 10mole (PEG-N) by using Launder-O-meter and artificial standard soiled cotton cloth.1) The effects of inorganic builders on soft and hard water.The concentration of PEG-N aqueous solutions was from 0.05g/

Study on wetting mechanism of nonionic silicone surfactant on coal dust

open access: yesHeliyon, 2023
Coal dust disasters are serious in coal mining. The use of nonionic surfactants can effectively improve the wettability of coal dust and reduce the content of suspended coal dust in the air.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Nonionic polymer surfactants [PDF]

open access: yesJournal of Polymer Science: Polymer Chemistry Edition, 1982
AbstractNonionic water‐soluble polymeric surfactants have been prepared by addition of long‐chain n‐alkyl epoxides to nonionic cellulose ethers. The polymers exhibit properties which can be explained by interchain association. The relationship between hydrocarbon‐modifier carbon number and the onset of association follows a linear relation analogous to

Cracking the Code: Which Ocular Symptoms Predict Dry Eye Signs? Insights From a Large International Sicca Registry

open access: yesArthritis Care &Research, EarlyView.
Objective The study aimed to identify symptom‐based predictors of dry eye disease (DED) signs in the Sjögren's International Collaborative Clinical Alliance (SICCA) cohort. Methods We performed a retrospective analysis examining 16 ocular symptoms (most graded 0–4) and artificial tear (AT) use (graded 0–3) as predictors of DED signs (abnormal ocular ...
