Investigation of flexoelectricity and ionic contamination in nematic liquid crystals

open access: yes, 2009
The work presented is a study of nematic liquid crystal physical properties. One of the phenomenon investigated is the bistability or in other words, the ability of the director of the material to rest in different orientations as function of the ...

Resolving the Cu(bdc) Conundrum: Identifying Non‐Porous Packing of Prototypical Coordination‐Network Thin Films Combining Advanced Diffraction Techniques and Computational Modelling

open access: yesAdvanced Functional Materials, EarlyView.
Solution‐processed Cu(bdc) forms prototypical MOF thin films for which a multitude of not fully satisfactory structural models have been suggested. Combining rotating grazing‐incidence diffraction and X‐ray reflectivity on two complementary samples with density‐functional theory, we first discard the previously suggested models and then identify a non ...

Nanoengineered Binetworks in Multifunctional Anionic Block Polymer Mesoblends for Improved Mechanical Properties

open access: yesAdvanced Functional Materials, EarlyView.
Mesoblends consist of a nanostructured polymer into which a second polymer is imbibed with a selective solvent. In this work, a solvent‐templatable pentablock terpolymer possessing a sulfonated midblock is modified with a hydrophilic polymer that is photocrosslinked in situ, yielding a hierarchical binetwork.

Local stability and a renormalized Newton Method for equilibrium liquid crystal director modeling

open access: yes, 2012
We consider the nonlinear systems of equations that result from discretizations of a prototype variational model for the equilibrium director field characterizing the orientational properties of a liquid crystal material.

Liquid-liquid Extraction of Copper(II), Cadmium(II), Lead(II) and Zinc(II) from Perchlorate and Tartrate Media by Di-2-methylnonylphosphoric Acid into Heptane [PDF]

open access: yes, 2009
The liquid-liquid extraction equilibrium of Cu(II), Cd(II), Pb(II) and Zn(II) from 0.10 M perchlorate medium by di-2-methylnonylphosphoric acid (DMNPA) as an extractant dissolved in heptane has been investigated.

Dynamic Interfacial Chemistry of Choline Chloride as Electrolyte Additive for Stable Zn‐Iodine Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Choline chloride (ChCl) additive enables dynamic interface engineering in Zn‐I2 batteries by forming hydrophobic polyiodide complexes and a Zn‐stabilizing Ch+‐rich layer under electric field modulation. This dual‐function strategy suppresses iodine hydrolysis and dendrite formation, while optimizing Zn2+ solvation and transport for high‐efficiency ...

Ultrasmall High‐Entropy Materials: Nanoscale Effects, Synthesis, and Mechanistic Insights

open access: yesAdvanced Functional Materials, EarlyView.
This review article focuses on sub‐10 nm high‐entropy materials that combine nanoscale design with complex compositions for next‐generation applications. ABSTRACT Ultrasmall high‐entropy nanomaterials (USHENMs, <10 nm) merge multicomponent chemistry with size‐dependent effects, forming a distinct class of materials with unprecedented properties.

Investigation on hollow fiber based liquid-liquid-liquid micro-extraction with different driving forces

open access: yes, 2011
In recent years, hollow fiber based liquid-liquid-liquid micro-extraction (HF-LLLME) [1] has been widely studied due to its higher enrichment factor, excellent ability of clean-up, and lower consumption of organic solvent.
