The solubilities of succinic acid in acetic acid + water solvent mixtures at (303.2 to 333.2) K and acetic acid + cyclohexane solvent mixtures at (303.2 to 343.2) K were determined. It was found that the solubility of succinic acid in acetic acid + cyclohexane mixtures increases with increasing mass fraction of acetic…
We introduce shell cross-linked protein/quantum dot (QD) hybrid nanocapsules as a serum-stable systemic delivery nanocarrier for tumor-targeted in vivo bio-imaging applications. Highly luminescent, heavy-metal-free Cu0.3InS2/ZnS (CIS/ZnS) core-shell QDs are synthesized and mixed with amine-reactive six-armed poly(ethy…
Substrate engineering is a key factor in the synthesis of new complex materials. The substrate surface has to be conditioned in order to minimize the energy threshold for the formation of the desired phase or to enhance the catalytic activity of the substrate. The mechanism of the substrate activity, especially of tec…
It is well established that the dropwise condensation (DWC) mode can lead up to significant enhancement in heat transfer coefficients as compared to the filmwise mode (FWC). Typically, hydrophobic surfaces are expected to promote DWC, while hydrophilic ones induce FWC. To this end, superhydrophobic surfaces, where a c…
We numerically investigate cooperative polymerization in an off-lattice model based on a pairwise additive potential using particles with a single attractive patch that covers 30% of the colloid surface. Upon cooling, these particles self-assemble into small clusters which, below a density-dependent temperature, spont…
OBJECTIVES: The clinical application of doxorubicin (DOX) is limited by severe systemic side effects. The aim of this study was to develop a strategy that combined the liposomal DOX (LipDOX) and intratumoral injection to reduce the toxicity and enhance the antitumor efficiency. METHODS: The pharmacokinetics, tissue di…
In this paper, we report ultra-thin liquid crystal films of semiconducting carbon nanotubes using a simple vacuum filtration process. Vacuum filtration of nanotubes in aqueous surfactant solution formed nematic domains on the filter membrane surface and exhibited local ordering. A 2D fast Fourier transform was used to…
The use of superhydrophobic surfaces to produce polymeric particles proves to be biologically friendly since it entails the pipetting and subsequent cross-linking of polymeric solutions under mild experimental conditions. Moreover, it renders encapsulation efficiencies of ∼100%. However, the obtained particles are 1 t…
Structure and piezoelectric coefficient ( d 33 ) of lead‐free 7.5% mole BaTiO 3 ‐doped ( Bi 0.5 Na 0.5 ) TiO 3 (BNT‐7.5%BT) polycrystalline piezoceramics have been characterized systematically as a function of poling electric ( E ) field. Dielectric permittivity and loss were also measured as functions of frequency an…
The micropatterning of layers of colloidal quantum dots (QDs) stabilized by inorganic ligands is demonstrated using PbS core and CdSe/CdS core/shell QDs. A layer-by-layer approach is used to assemble the QD films, where each cycle involves the deposition of a QD layer by dip-coating, and the replacement of the native…
The ageing characteristics of flame-made 2 wt% Pd supported on YFeO3 were analysed in comparison with a Pd/Al2O3–CeO2–ZrO2 three-way catalyst (TWC) with respect to structural changes and catalytic performance for methane oxidation under stoichiometric reaction conditions. Thermal treatment under lean conditions (air,…
We propose an ultra-thin elastic cloak to control the scattering of bending waves in isotropic heterogeneous thin plates. The cloak design makes use of the scattering cancellation technique applied, for the first time, to the biharmonic operator describing the propagation of bending waves in thin plates. We first anal…
The mollusk shell is a complex biological material that integrates mineral phases with organic macromolecular components such as proteins. The role of proteins in the formation of the nacre layer (aragonite mineral phase) is poorly understood, particularly with regard to the organization of mineral deposits within the…
Ba2HgS5 was synthesized by cooling a molten mixture of BaS, HgS, and elemental sulfur. It crystallizes in the orthorhombic Pnma space group with a = 12.190(2) Å, b = 8.677(2) Å, c = 8.371(2) Å, and dcalc = 4.77 g cm(-3). Its crystal structure consists of isolated dumbbell-shaped (HgS2)(2-) and v-shaped S3(2-) ions. Th…
The remarkable mechanical strength of cellulose reflects the arrangement of multiple β-1,4-linked glucan chains in a para-crystalline fibril. During plant cellulose biosynthesis, a multimeric cellulose synthesis complex (CSC) moves within the plane of the plasma membrane as many glucan chains are synthesized from the…
The total, triplet, and pair contributions to the entropy with increasing tetrahedrality are mapped out for the Stillinger-Weber liquids to demonstrate the qualitative and quantitative differences between triplet-dominated, tetrahedral liquids and pair-dominated, simple liquids with regard to supercooling and crystall…

We studied the electric conductivity and structure of polymer‐derived carbon‐rich amorphous SiC pyrolyzed at different temperatures. The conductivity of the material increased drastically with pyrolysis temperature followed an Arrhenius relationship with the activation energy of ~3.4 eV. Raman and X‐ray photoelectron…
Layer-by-layer (LbL) assembly is a self-assembly technique used to develop multilayer films based on complementary interactions between film components. These multilayer films have had a significant impact on the fields of cellular and tissue engineering. The aim of cellular engineering is to understand and control ce…
The inherent strength of individual carbon nanotubes (CNTs) offers considerable opportunity for the development of advanced, lightweight composite structures. Recent work in the fabrication and application of CNT forms such as yarns and sheets has addressed early nanocomposite limitations with respect to nanotube disp…
