A novel kind of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate)-based monolithic column was developed for LC by directing supramolecular self-assembly of high internal phase emulsion. Mercury intrusion porosimetry characterization and scanning electron microscope pictures showed that these monoliths pres…
Transparent and conductive oxide (TCO) films with a cubic perovskite structure, lanthanum-doped strontium stannate La x Sr 1− x SnO 3 ( x = 0–0.15) (LSSO), have been grown epitaxially on SrTiO 3 (0 0 1) substrates by the pulsed laser deposition method. The doping concentration and growth parameters were optimized base…
The sinterability of yttrium-doped barium zirconate (BZY) has been improved through an original synthesis approach giving a core−shell type arrangement in which nanoparticulate BZY is enrobed by a thin coating of yttrium-doped barium cerate (BCY). A flash combustion route was first used to prepare BZY10 (10% yttrium-d…
A novel amphiphilic cyclic peptide composed of two beta-glucosamino acids and one trans-2-aminocyclohexylcarboxylic acid was synthesized and investigated on assembly formation. The cyclic tri-beta-peptide was self-assembled into rodlike crystals or nanofibers depending on preparative conditions. The rodlike crystals s…
Abstract This work addresses the issue of determining the number of layers in few layers of graphene (FLG) flakes by cross‐comparison of several techniques: optical microscopy (OM), atomic force microscopy (AFM) and micro‐Raman (μR) spectroscopy. SL were preliminarily identified by μR spectroscopy, which allows an una…
N-(L-valyl-L-valyl-L-valyl)azobenzene-4-carboxamide [Azo(LVal)(3)] is a low molecular weight gelator that forms a photofunctional fibrous assembled system; this assembly undergoes dispersion/reorganization upon trans-to-cis photoisomerization, which, as a result of the breaking and reforming of hydrogen bonds, induces…
This article describes an evaluation of the mechanical properties and sound insulation effects of composites made of acrylonitrile butadiene styrene (ABS) and carbon-black using the design of experiment (DOE) approach. The solution blending process and method are presented. The effect of the acetone content in ABS dur…
Abstract Utilization of naturally available raw materials for the fabrication of eco‐friendly functional materials has long been desired. In this work, a series of superabsorbent nanocomposites were prepared by radical solution copolymerization of sodium carboxymethyl cellulose (CMC), partially neutralized acrylic aci…
We study domain growth upon the light-induced phase separation (LIPS) in the spin-crossover $[\text{Fe}{(\text{ptz})}_{6}]{({\text{BF}}_{4})}_{2}$ single crystal under clarified conditions of intensity of light and temperature. Our primary motivation is to model the relaxation behavior of a spin-crossover system under…
We used enhanced piezo-response force microscopy (E-PFM) to investigate both ferroelastic and ferroelectric nanodomains in thin films of the simple multi-ferroic system PbZr(0.3)Ti(0.7)O(3) (PZT). We show how the grains are organized into a new type of elastic domain bundles of the well-known periodic elastic twins. H…
I review here form, or textural, birefringence (Δ(F)) in the context of advances in the field, as well as with regard to findings and applications in the physics of photonic devices, fibers maintaining polarization, photonic crystal fibers, and in biopolymers present in extracellular matrices and the myelin sheath. So…
Abstract This paper presents the results of comparative analysis of Raman scattering spectra of CdSe/ZnS QDs covered by polymer with and without bio‐conjugation to the mouse anti PSA (Prostate‐Specific Antigen) antibodies (mab). Commercial CdSe/ZnS QDs used in the study are characterized by the color emission with the…
Luminescent SiN-based multilayers were prepared in a plasma enhanced chemical vapor deposition system followed by subsequently laser crystallization of ultrathin amorphous Si-rich SiN sublayers. The cross-sectional TEM analysis reveals that grain size of Si nanocrystals embedded in the Si-rich SiN sublayers is indepen…
We developed specific negative tone resists suitable for preparing periodic inorganic nanostructures by ArF photolithography. This approach is based on the sol-gel chemistry of modified metal alkoxides followed by DUV laser irradiation. Patterning at the nanoscale was demonstrated by using an achromatic interferometer…
Poly( l -lactide) (PLLA) and poly( l -lactide)/poly(ethylene glycol) (PLLA/PEG) electrospun fibrous materials coated with a polyelectrolyte complex (PEC) were prepared. This was achieved by consecutive deposition of a layer of N -carboxyethylchitosan (CECh) and a layer of a double hydrophilic block copolymer, poly(eth…
ABSTRACT This paper studies the fracture behaviour of cracked carbon nanotube (CNT)‐based polymer composites by a combined numerical–experimental approach. Tensile tests were conducted on single‐edge cracked plate specimens of CNT/polycarbonate composites at room temperature and liquid nitrogen temperature (77 K), and…
Epitaxy is a form of two-dimensional heterogeneous nucleation in which the substrate induces a particular crystal phase of another compound. Here we describe the epitaxial sublimation behavior of a structurally related compound, mefenamic acid on the (100) faces of flufenamic acid form I and III single crystals. Raman…
Using hydrothermal methods, a new series of five M(I)−Nb(V) oxyfluoride hybrid solids was prepared having the compositions [Cu(pyz)] 2 NbOF 5 ( 1, pyz = pyrazine), Ag(pyz)NbOF 4 ( 2 ), M(bpy)NbOF 4 ·2H 2 O ( 3, M = Cu; 4, M = Ag; bpy = 4,4′-bipyridine), and [Cu(dpe)] 2 NbOF 5 ·8H 2 O ( 5, dpe = 1,2-bis(4-pyridyl)-ethe…
Herein we report the first hybrid magnetic material resulting from the intercalation of a cyanide-based molecular magnet into a solid-state layered host. More specifically, the use of a diamagnetic cationic Zn(II)-Al(lII) layered double hydroxide host allows for the formation of an anionic two-dimensional ferromagneti…
A strategy to synthesize mesoporous SrTiO3 and BaTiO3 powders by using in situ inorganic carbonate pore-makers was reported. The carbonate pore-makers are stable at high temperature and can support the target mesostructures. The other important role of carbonate is to inhibit the growth of crystals, thus improving the…
