A facile method to develop electro-induced shape memory polymer composites with good location- and process-controlled shape recovery performance is proposed. The poly(butylene succinate) (PBS)–poly(ethylene glycol) (PEG) multiblock copolymer (PBSEG), which has excellent flexibility, was chosen as the matrix of the com…
A panoramic overview of the leather world market is given. The industrial tanning process is schemat- ically explained giving a general outline of how an animal skin is transformed into a durable material having many different characteristics according to its specific future use. All the tanning industrial steps are o…
From the viewpoint of developing photoresponsive supramolecular systems in microenvironments to exhibit more sophisticated photo-functions even at the macroscopic level, inorganic/organic hybrid compounds based on clay or niobate nanosheets as the microenvironments were prepared, characterized, and examined for their…
A new functional triphenylamine-based (TPA-based) aromatic polyether (OXPE) derived from 2,5-bis(4-fluorophenyl)-1,3,4-oxadiazole and 4,4′-dihydroxytriphenylamine and polyester (6FPET) derived from 4,4′-(hexafluoroisopropylidene)bis(benzoyl chloride) and 4,4′-dihydroxytriphenylamine were synthesized and used for memor…
A new straightforward method for the synthesis of gold nanoparticles from addition of cyclohexanone to aqueous solutions of auric acid at room temperature is presented. By understanding this process we have discovered a new organic chemistry transformation reaction for converting cyclic ketones to α-chloro ketones and…
The Inhibitive and adsorption properties of aqueous extract of seeds of Garcinia indica extract (GIE) have been studied for corrosion control of aluminium in 0.5 M phosphoric acid solution using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques at to . The effects of inhibitor co…
X-ray diffraction analysis and orientation contrast scanning electron microscopy imaging of La0.7Sr0.3MnO3 epitaxial layers grown on (001)-SrTiO3 substrates have been used to track the shear strain and twin domain period as a function of the thickness of the films, t. To this end, the diffraction by a periodically mod…
In the present work, we develop an effective strategy, i.e., carbon nanomaterial-assisted morphological tuning, for both thermodynamic and kinetic destabilization in complex hydrides based on the interaction between the complex anion and the carbon matrix. The NaAlH4/carbon nanomaterials of graphene nanosheets (GNs),…
High-resolution anion photoelectron spectra of the Group 4 metal dioxides TiO2(-), ZrO2(-), and HfO2(-) are reported, using slow electron velocity-map imaging (SEVI) combined with ion trapping and cryogenic cooling. The resulting spectra exhibit sub-meV resolution with no congestion from hot bands. Electron affinities…
Bimetallic ruthenium-copper nanoparticles embedded in the pore walls of mesoporous carbon were prepared via a template route and evaluated in terms of catalytic properties in D-glucose hydrogenation. The existence of bimetallic entities was supported by Ru L3-edge and Cu K-edge X-ray absorption results. The hydrogen s…
Novel capsule clusters with a capsule-in-capsule structure were facilely fabricated by polymerization based on capsule-in-water-in-oil Pickering emulsions. First, dibutyl phthalate (DBP)-loaded polyurea (PU) capsules were prepared via interfacial polymerization templated from oil-in-water Pickering emulsions stabilize…
A ferromagnetic intramolecular dipolar interaction is observed and verified by both experimental studies and ab initio calculations on a dinuclear holmium(III) complex [Ho2(H2cht)2Cl4(H2O)(MeCN)]·MeCN.
Nanoindentation studies on thin films of the widely used azo polymer pDR1A and a supramolecular polymer–azobenzene complex p4VP(DY7)0.5 demonstrate significant light-induced softening upon visible-light irradiation due to trans–cis–trans photoisomerization of the azobenzene units. More specifically, the strain-rate se…
Magnesium oxide coated multiwalled carbon nanotubes (MgO@MWNT) were fabricated and dispersed into epoxy matrix. The microstructures of MgO@MWNT and epoxy/MgO@MWNT nanocomposites were characterized by TEM and SEM. Electrical resistivity and thermal conductivity of epoxy nanocomposites were investigated with high resist…
This study related to the development of bio-degradable composites using areca nut frond fibers for use in low strength applications. The fronds are immersed in water for 72 hours to extract the fibers. The extracted fibers were treated with alkaline solution. The fibers are dried in ambient conditions for 24 hours. A…
The main objective of this article is to introduce a new natural fiber as a reinforcement in polymers for making composites for lightweight applications. The extraction of golden cane (Chrysalidocarpus lutescens) fiber and the mechanical properties of the fiber-reinforced polyester composites are described. The compos…
A simple hydrothermal method was employed to synthesize AgFeO2 nanoparticles, which were utilized as substrates in SERS detection of Rhodamine 6G and 4-mercaptobenzoic acid. The magnetic properties of the products provided the capability of concentrating analyte molecules under an external magnetic field. The detectio…
A triad based on triarylamine donors, an iridium dipyrrin sensitiser and a naphthalene diimide acceptor is investigated using fs-pump-probe spectroscopy at two different pump wavelengths. Excitation of the naphthalene diimide induces a stepwise electron transfer process that yields within ca. 100 ps a charge separated…
We report a facile one–pot synthesis of CexZr1−xO2 (0 ≤ x ≤ 1) solid solution nanocrystals using hydrothermal reactions.
