An environmentally friendly and controllable P(VDF-co-CTFE) hydrogenation route involving the transition-metal complex mediated radical chain transfer reaction is successfully developed to synthesize P(VDF-co-CTFE-co-TrFE). The typical transition metal catalysts of ATRP reaction could be applied in this process.
We have re-investigated the structural identity of the famous gold-phosphine-halide Au:PR3:X compound having 55–69 gold atoms and core size of 1.4 nm (similar to “Schmid gold” or Nanogold®) from the viewpoint of the Superatom-Complex (SAC) model for ligand protected metal clusters, and in consideration of the ligand-a…
This article presents the first example of ultra-small (3-4 nm) magneto-luminescent cyano-bridged coordination polymer nanoparticles Ln0.33(3+)Gdx3+/[Mo(CN)8]3- (Ln=Eu (x=0.34), Tb (x=0.35)) enwrapped by a natural biocompatible polymer chitosan. The aqueous colloidal solutions of these nanoparticles present a luminesc…
In this work we present a novel water soluble spiropyran photoswitch that can be photonically activated inside live cells from a form that has no significant effect on the cellular survival to a form that induces a dramatic toxic response.
Stable superhydrophobic meshes with a biomimetic hierarchical structure were fabricated via simple electropolymerization and chemical polymerization processes. Because the multi-scale hierarchical structure provides a stable superhydrophobic state by maintaining a Cassie state, these meshes have high static and dynami…
The desired bioavailability and the method of drug administration and delivery can require stringent control on the crystal size distribution. Optimal control strategies are proposed to manufacture crystals with a targeted size distribution by combining controlled seeding by impinging jet crystallization with a batch…
Two printing methods, extrusion and inkjet, are used to deposit tracks of PEDOT/PSS conducting polymer onto biopolymer films with a view to prepare implantable tissue mimics containing electronic devices. Extruded tracks offer lower printing resolution, but better electrical characteristics compared to inkjet printed…
Bioplastics are naturally occurring biodegradable polymers made from polyhydroxyalkanoates (PHA) of which poly 3-hydroxy butyric acid (PHB) is the most common. PHB serves as an energy storage molecule and accumulates intracellularly as storage granules in microbes. This work utilized the biodiversity of bacteria to is…
Image and spectral intensity from bicarbonate-selective europium(III) probes localised in the mitochondria of cells is modulated reversibly by variation of external pCO(2), and is suppressed by addition of the carbonic anhydrase inhibitor, acetazolomide.
Immobilization of the chiral salen-metal complex [Mn(III)(salen)(H(2)O)(2)ClO(4)] on the Keggin-type polyoxometalate (POM) skeletons leads to the isolation of POM derivatives functionalized with chiral salen-metal complexes, which represent the first examples of introducing chiral salen-metal complexes into the POM sy…
Besides the problem of low ductility and poor notch toughness of ferritic stainless steel welds due to the microstructure characteristics of the weld section as a result of the weld heat input rate and the heat transfer factor, susceptibility to intergranular corrosion caused by the depletion of the chromium content o…
This work presents the synthesis and studies of a red-NIR luminescent liquid crystal compound based on an octahedral metallic cluster core orthogonally bounded to six non-mesogenic organic ligands. It evidences synergetic effects between the organic and inorganic parts of the hybrid, resulting in the generation of liq…
The effect of accelerated weathering on the visual appearance and on mechanical properties of high impact polystyrene (HIPS) as well as HIPS reinforced with mercerized and bleached sugarcane bagasse fibers composites are investigated. After accelerated weathering period of 900 h, under UV-B radiation and moisture regu…
Photochromic dithienylethene (DTE) derivatives, M-DTE-M (M: M(η(5)-C(5)R(5))L(2); M = Fe, Ru; R = H, Me; L = CO, phosphine), with direct σ-bonded, redox-active organometallic attachments are prepared and their response to photo- and electro-chemical stimuli as well as wire-like and switching performance has been inves…
Two new amino acid based low-molecular-mass organic gelators were designed, synthesized, and examined for their ability to gelate various organic solvents. The gelator molecules were found to aggregate via N–H⋯O hydrogen bonding to form an interwinding 3D network which immobilized a large number of organic solvents. A…
Electromagnetic metamaterials are artificial materials composed of subwavelength structures to provide unusual effective macroscopic behavior not found in nature. These materials are characterized by constitutive relations which contain a maximum of 36 complex constitutive parameters. With different combinations of po…
MnO(2)/TiN nanotubes are fabricated using facile deposition techniques to maximize the surface area of the electroactive material for use in electrochemical capacitors. Atomic layer deposition is used to deposit conformal nanotubes within an anodic aluminium oxide template. After template removal, the inner and outer…
In this review article, we have illustrated the strategies developed to achieve inorganic-organic hybrid compounds with technologically important physical properties. A series of target inorganic-organic hybrid compounds have been accomplished by incorporating the functional organic components (with a large hyperpolar…
We demonstrated the conceptual advantage of encoded superparticles (SPs) based on the upconverted luminescence (UCL) spectral signature. In this research, mass fabrication of UCL-encoded SPs has been achieved by employing a facile, robust, and low-cost self-assembly in microemulsion droplets, which offered a convenien…
In this study, chitin nanofibers were at first successfully prepared using aqueous counter collision (= ACC) method. Dispersion states of the chitin nanofibers in water were compared with aqueous dispersion of cellulose nanofibers in dynamic viscoelastic properties. Morphology of the chitin nanofibers was observed by…
