A Versatile Approach to Stabilize Liquid-Liquid Interfaces using Surfactant Self-Assembly

Julian Charles Shillcock

Stabilizing liquid-liquid interfaces, whether between miscible or immiscible liquids, is crucial for a wide range of applications, including energy storage, microreactors, and biomimetic structures. In this study, a versatile approach for stabilizing the w ...

Colloidal Atomic Layer Deposition on Nanocrystals Using Ligand-Modified Precursors

Raffaella Buonsanti, Anna Loiudice, Petru Pasquale Albertini, Ona Segura Lecina, Philippe Benjamin Green, Jari Leemans, Mark Adrian Newton, Coline Marie Agathe Boulanger, Krishna Kumar

Atomic layer deposition (ALD) is a method to grow thin metal oxide layers on a variety of materials for applications spanning from electronics to catalysis. Extending ALD to colloidally stable nanocrystals promises to combine the benefits of thin metal oxi ...

Long live(d) CsPbBr3 superlattices: colloidal atomic layer deposition for structural stability

Raffaella Buonsanti, Philippe Benjamin Green, Alexander Nicolas Chen

Superlattice formation afforded by metal halide perovskite nanocrystals has been a phenomenon of interest due to the high structural order induced in these self-assemblies, an order that is influenced by the surface chemistry and particle morphology of the ...

Microcomputed Tomography Technique for In Vivo Three-Dimensional Fat Tissue Volume Evaluation After Polymer Injection

Harm-Anton Klok, Ioana Konz

Tissue engineering technologies are new and promising techniques in fat tissue reconstruction. However, to assess their efficacy before any clinical application, in vivo experiments are mandatory. This study assesses whether microcomputed tomography (CT) s ...

Synergistic effect of carboxylic and amine ligands on the synthesis of CdSe nanocrystals

Martinus Adela Maria Gijs, Virendra Kumar Parashar

We demonstrate the drastic improvement in absorbance and photoluminescence (UV-PL) of CdSe nanocrystals (NCs) upon adding both a carboxylic acid and an amine ligand to the cadmium acetate green chemistry source. We combined carboxylate complexes of lauric ...

Working fluid charge reduction. Part II: Supercritical CO2 gas cooler designed for light commercial appliances

John Richard Thome, Jackson Braz Marcinichen

The present study focused on the thermal hydraulic performance improvement of a CO2 gas cooler with the principal goal of reducing its volume, and consequently the necessary charge of the working fluid. To achieve this compactness, the leading methods for ...

Structure and Biophysical Properties of a Triple-Stranded Beta-Helix Comprising the Central Spike of Bacteriophage T4

Laure Menin, Petr Leiman, Sergii Buth

Gene product 5 (gp5) of bacteriophage T4 is a spike-shaped protein that functions to disrupt the membrane of the target cell during phage infection. Its C-terminal domain is a long and slender -helix that is formed by three polypeptide chains wrapped aroun ...

Synthesis of magnetic cobalt ferrite nanoparticles with controlled morphology, monodispersity and composition: the influence of solvent, surfactant, reductant and synthetic conditions

In our present work, magnetic cobalt ferrite (CoFe2O4) nanoparticles have been successfully synthesised by thermal decomposition of Fe(III) and Co(II) acetylacetonate compounds in organic solvents in the presence of oleic acid (OA)/oleylamine (OLA) as surf ...

Metal accumulation and response of antioxidant enzymes in seedlings and adult sunflower mutants with improved metal removal traits on a metal-contaminated soil

Jean-Paul Schwitzguebel, Erika Nehnevajova

Sunflower mutant lines with an enhanced tolerance and metal accumulation capacity obtained by mutation breeding have been proposed for Zn, Cd and Cu removal from metal-contaminated soils in previous studies. However, soils contaminated with trace elements ...

A Promising Technique to Increase Metal Concentration and Extraction in Sunflowers

Jean-Paul Schwitzguebel, Erika Nehnevajova

Since most of the metal-hyperaccumulating wild plants only produce very low biomass and many high-yielding crops accumulate only moderate amounts of metals, the current research is mainly focused on overcoming these limitations and the optimization of meta ...

Screening of sunflower cultivars for metal phytoextraction in a contaminated field prior to mutagenesis

Jean-Paul Schwitzguebel, Erika Nehnevajova

Sunflower can be used for the remediation of metal-contaminated soils. Its high biomass production makes this plant species interesting for phytoextraction and using sunflower oil for a technical purpose may improve the economic balance of phytoremediation ...

Non-GMO approach for the improvement of heavy metal accumulation and extraction of high yielding crop species for efficient phytoextraction of contaminated soil

Erika Nehnevajova

Some plants able to take up heavy metals from contaminated soils offer a possibility to clean up sites contaminated with heavy metals. Plants thus act as a solar driven pump, which can extract and concentrate heavy metals from the environment. Since most o ...
