Peripherally π-extended N-confused porphyrin rhenium complexes were synthesized by the rhenium-mediated reactions of N-confused porphyrins with 2-methyl azaarene and the structures were elucidated by X-ray crystallographic analyses. Extension of the π-conjugation in the complexes was supported by the absorption spectr…
We give an update of the situation concerning the effect of electron–electron interactions on the physics of a neutral graphene system at low energies. We revise old renormalization group results and the use of 1/ N expansion to address questions of the possible opening of a low-energy gap, and the magnitude of the gr…
Coarse-grained Metropolis Monte Carlo Brownian Dynamics simulations are used to clarify the ultralow friction mechanism of a transfer film of multilayered graphene sheets. Each circular graphene sheet consists of 400 to 1,000,000 atoms confined between the upper and lower sliders and are allowed to move in 3 translati…
In this paper, firstly the surface plasma resonance (SPR) was used to evaluate the antifouling property of polydopamine-graft-poly(ethylene glycol) (PEG) copolymer coating, and then the quantitative analysis of food proteins (such as hen eggs and milk powder) was investigated by capillary electrophoresis (CE) method u…
To synthesize the silver nanoparticles (AgNPs) using the extracts of Hypnea sp. and to investigate the antibacterial activity against Eshcherichia coli, Staphylococcus aureus and invitro cytotoxic activity on HT-29. In the present study, AgNPs were synthesized using the aqueous extract of marine macro-algae, and were…
Single-crystal ZnO nanowires long up to several microns were fabricated by one-step electrochemical deposition. A template-based process employing track-etched polycarbonate (TE-PC) membranes was used for this purpose. The morphology and the structure characteristics of the ZnO nanowires were analyzed by means of Scan…
Cooperative binary ionic (CBI) solids comprise a versatile new class of opto-electronic and catalytic materials consisting of ionically self-assembled pairs of organic anions and cations. Herein, we report CBI nanocomposites formed by growing nanoparticles of one type of porphyrin CBI solid onto a second porphyrin CBI…
Multiferroic polycrystalline BiFe1-xMnxO3 (0 ≤ x ≤ 0.3) thin films have been prepared on the Pt(111)/Ti/SiO2/Si(100) substrates by pulsed laser deposition method. The influence of Mn substitution on the electronic structure and magnetic properties has been studied. X‐ray diffraction spectroscopy shows that Mn substitu…
Single walled carbon nanotube (SWCNT) networks present outstanding potential for the development of SWCNT-based gas sensors. Due to the complexity of the transport properties of this material, the physical mechanisms at stake during exposure to gas are still under debate. Previously suggested mechanisms are charge tra…
A new metastable bi-component hydrogel of thymine and 6-methyl-1,3,5-triazine-2,4-diamine, that can also cage a number of organic solvents, has different stabilities depending on its synthesis; the ultrasound induced gels transform more quickly into a crystalline precipitate than the thermo gels and the structural, th…
Zn-loaded bovine serum albumin nanoparticles (Zn-BSA nanoparticles) were prepared and used as carriers for pH-responsive anticancer drug delivery. Zinc was introduced into this system to increase the stability of the BSA nanoparticles and to load the anticancer drug based on the coordination bonding formation of Zn-BS…
Four new dinuclear complexes [Ni(μ-L)(μ-OAc)Ni(H2O)2]NO3 (1), Ni(μ-L)(μ-OBz)Ni(H2O)(MeOH)]NO3·3MeOH (2), [Ni(μ-L)(μ-9-An)Ni(H2O)(MeOH)]NO3 (3) and [Ni(μ-L)(μ-OAc)Ni(H2O)(N3)]·CH3OH (4) have been prepared from the compartmental ligand N,N′,N′′-trimethyl-N,N′′-bis(2-hydroxy-3-methoxy-5-methylbenzyl)diethylenetriamine (H…
Calcium vanadate nanorods with sheaf-shaped structures have been synthesized by a facile hydrothermal route using calcium acetate and sodium orthovanadate as the raw materials. The as-prepared calcium vanadate nanorods are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission elect…
A novel boron-containing π-conjugated compound has been synthesized by the introduction of electron-acceptors (dimesitylboron groups) at the 3,3'-positions of a carbazole dimer (electron-donor). The compound possesses excellent electrochemical properties and high fluorescence quantum yields. In addition, is a sensitiv…
We predict that tetrahedral Ce(n)O(2n) nanoparticles <2 nm in size become more stable than those experimentally observed at larger sizes with truncated octahedral morphologies, based on global optimisation and density functional calculations.
In this work, we reported several kinds of highly stable, effective mesoporous Au/TiO2 sphere-based solid acid catalysts with large specific surface areas and good monodispersity in the reaction medium. In this process, monodisperse titanium glycolate spheres were first formed by an antisolvent precipitation route, an…
New heteropolyanion-based polymeric hybrids prepared by the anion-exchange of newly task-specific designed ionic copolymers with Keggin heteropolyacids are revealed to be highly efficient, conveniently recoverable, and steadily reusable catalysts for the oxidation of alcohols with H2O2.
Hierarchical structures of transition metal oxides with well-defined compositions are crucial for achieving advanced electrodes for energy storage devices. Herein, we first demonstrate the hierarchically structured MoO(3) assembled by twisted nanoribbons with a hybrid composition for improved rate capability and cycle…
In this research work, the glasses were prepared by rice husk ash from Yasothon Province, Thailand. The result shows that, after sintered at 1,000 °C (RHA sample), rice husk ash can be used in colorless and color glass production. The color glass can be prepared from RHA and showed light blue (CuO doped), brown (MnO2…
The production cost of flexible polyurethane foam is significantly dependent on the cost of polyol, which constitute the largest percentage of materials used in foam production with the characteracterics to induce superior mechanical properties. Suitable fillers that are relatively cheap can be introduced in the foam…
