Fabrication of Magnetite Nanoparticles With Hydrophobic Imidazolium Ionic Liquid for the Efficient Role in Oil Spill Collection

Journal of Chemistry
As one of the main environmental obstacles, oil spill causes serious consequences on the environment, fauna, and flora. The traditional methods for cleaning up oil spills were found time-consuming, expensive, and ineffective. Magnetite nanoparticles have

Influence of Green Corrosion Inhibitor based on Chitosan Ionic Liquid on the Steel Corrodibility in Chloride Solution

International Journal of Electrochemical Science, 2015
Ionic liquids ( ILs) attracted great attention as green corrosion inhibitors for steel in aggressive environments. The present work synthesize new IL using chitosan through amidation and quaternization reaction with oleic acid and p-toluene sulfonic acid,

Self-assembly of multi-component fluorescent molecular logic gates in micelles [PDF]

, 2016
A recent strategy for developing supramolecular logic gates in water is based on combinations of molecules via self-assembly with surfactants, which eliminates the need for time-consuming synthesis. The self-assembly of surfactants and lumophores and

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

A finite membrane element formulation for surfactants

, 2019
Surfactants play an important role in various physiological and biomechanical applications. An example is the respiratory system, where pulmonary surfactants facilitate the breathing and reduce the possibility of airway blocking by lowering the surface ...

Detecting microplastics pollution in world oceans using SAR remote sensing [PDF]

, 2018
Plastic pollution in the world’s oceans is estimated to have reached 270.000 tones, or 5.25 trillion pieces. This plastic is now ubiquitous, however due to ocean circulation patterns, it accumulates in the ocean gyres, creating “garbage patches”.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

A New Green Ionic Liquid-Based Corrosion Inhibitor for Steel in Acidic Environments

Molecules, 2015
This work examines the use of new hydrophobic ionic liquid derivatives, namely octadecylammonium tosylate (ODA-TS) and oleylammonium tosylate (OA-TS) for corrosion protection of steel in 1 M hydrochloric acid solution.

The removal of thermally aged films of triacylglycerides by surfactant solutions [PDF]

, 2013
Thermal ageing of triacylglycerides (TAG) at high temperatures produces films which resist removal using aqueous surfactant solutions. We used a mass loss method to investigate the removal of thermally aged TAG films from hard surfaces using aqueous ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.
