Hollow polymeric capsules prepared from Layer-by-Layer coating of colloidal templates with polyelectrolyte multilayers are promising materials for drug delivery and release applications. Details of the wall structure arising from the core dissolution process are investigated by high resolution scanning electron micros…
Titanium dioxide thin films were deposited on (0001) α-quartz substrate by spray pyrolysis method. The method which an aerosol of Titanium Butoxide, generated ultrasonically, was sprayed on the substrate at temperature of 400°C, kept at this temperature for periods of 3, 13, 19 and 39 hours. The developed films at a c…
The use of "double-headed" phenolic oximes produces a trigonal antiprismatic [Fe(III)(3)](2) cluster with an "internal cavity" filled with an additional Fe(3+) ion. Magnetic measurements reveal that the competition between different exchange interactions leads to a low-spin ground multiplet weakly separated in energy…
This paper presents an in situ spectroelectrochemical characterization of polyazulene (PAz) and PAz-C(60) composite films using Fourier Transform Infrared Attenuated Total Reflection (FTIR-ATR) spectroscopy. In situ FTIR-ATR spectra were recorded simultaneously as the films were charged and discharged electrochemicall…

Driven by environmental concerns, new polymers based on renewable resources are arriving on the market to replace conventional polymers, obtained from petroleum, for different applications like food packaging. One of the most prominent polymers among these materials is poly(lactic acid) (PLA), a biodegradable, thermop…
Smectic liquid crystals with 'de Vries-like' properties are characterized by a maximum layer contraction of ≤1% upon transition from the non-tilted SmA phase to the tilted SmC phase. We show herein that one can systematically increase the 'de Vries-like' character of a smectic liquid crystal by tuning the frustration…
A new method for the preparation of macroporous silicon carbide using a polyHIPE approach is presented (polyHIPE = polymerized High Internal Phase Emulsion). A liquid preceramic precursor is copolymerized with styrene and the crosslinker divinylbenzene in different ratios and two different initiators. The resulting PC…
There are many ways to reduce plastic waste in the environment. Bio-based plastic could be a best solution for sustainable environment. In this article bio-based plastic were prepared. Potato starch and corn starch as a biopolymer blending with polyethylene. Samples buried into soil for eight months and put in aerated…
The precipitation condition of LaPO4 in phosphoric acid solution was investigated under both atmospheric and humidified conditions. The crystal morphology, Sr doping level, H2O incorporation, and high temperature stability of Sr-doped LaPO4 precipitates were also analyzed. Increasing pH2O from 0.01 to 1 atm extends th…
We present an experimental study on the surface rheology of ultrathin films of poly(tert-butylacrylate) (PTBA) and poly(tert-butylmethacrylate) (PTBMA) for which steric hindrance imposed by the methyl group leads to a large intrinsic rigidity of the polymer chain. Whilst PTBA films show weak temperature dependence, PT…
Plasma lithography is a template-guided self-assembly nanomanufacturing strategy for creating functional engineering devices using nanoscale and molecular building blocks. To elucidate the plasma lithography manufacturing process, the comparative binding of colloidal quantum dots on plasma patterned surface templates…
Drug delivery using biodegradable polymeric microparticles is becoming an important means of delivering therapeutic agents. In this work, we describe polyoxalate microparticles as a biodegradable and biocompatible protein drug-delivery system. Polyoxalate was synthesized from a polycondensation reaction between oxalyl…

A thermodynamic model is used to investigate the electrocaloric response of thin film perovskite ferroelectrics under the influence of differing electrical, thermal and mechanical boundary conditions including bias and driving field, temperature, lateral clamping and misfit strain. A comparison of the electrothermal p…
We report here a novel chemical solution method to site-selectively deposit and arrange palladium (Pd) nanoparticles (NPs) on single-walled carbon nanotubes (SWCNTs). Sodium dodecyl sulfate (SDS) formed supramolecular self-assemblies on the SWCNTs. The SDS then acted as adsorption sites for Pd(II) ions. Pd(II) was red…
A new polymer, poloxamine-polylysine acrylate (PPA), was synthesized for tissue-engineering applications. Polylysine was used to confer endothelial cell attachment properties to the poloxamine-based polymer, while the acrylate groups made it photo-cross-linkable. The PPA polymer was synthesized in three reaction steps…
Single crystal silver wires can be grown at the nitrobenzene|water interface when silver ions dissolved in the aqueous phase are reduced by decamethyl ferrocene dissolved in the nitrobenzene phase. The successful growth of these wires depends on a number of experimental conditions, most prominently on the concentratio…
Ordered macroporous nanoparticle thin films are achieved on porous substrates by combining ultrathin metal hydroxide nanostrands, colloidal crystal templates and the advantage of filtration technique. The preformed nanostrands layer plays two key roles for both uniform formation of hexagonal close-packed latex colloid…
Implementing an annealed porous silicon Bragg reflector between a crystalline silicon thin-film solar cell and its cheap silicon substrate improves greatly its performance. Such a multilayer features indeed a high reflectivity, allowing the optical confinement which is essential for these cells. Annealing the porous s…
