The structural stability, mechanical properties, and dynamical properties of T carbon-like structures were extensively studied by first-principles calculations using density functional theory. A novel modulated T carbon-like carbon allotrope (T-II carbon) is predicted by means of first principles calculations. This st…
A highly flexible supercapacitor is fabricated through a simple solution-based method in which conformal ultrathin (2 nm) nickel hydroxide (Ni(OH)2) layer is deposited on vertically grown zinc oxide (ZnO) nanowires on a three-dimensional, highly conductive textile substrate. The conformal ultrathin Ni(OH)2 layer enabl…
A metallosupramolecular polymer (MP-Zn) bearing dibenzo-24-crown-8 (DB24C8) arms is constructed by coordinating Zn(2+) with a conjugated bis-terpyridine ligand, which indicates concentration-dependent emissions from cyan to white to yellow. Successively, reversible emissions are realized by acid-base controllable reco…
VO2 nanostructures are attractive materials because of their reversible metal-insulator transition (MIT) and wide applications in devices. When they are used as field emitters, a new type of temperature-controlled field emission device can be fabricated. Vapor transport methods used to synthesize traditional VO2 nanos…
A colorimetric sensor decorated with β-cyclodextrin and adamantine has been designed to enhance the sensitivity of Mn <sup>2+</sup> detection.
The rationalisation of the influence of acidity and pore size of several solid oxides so that they selectively act as supports for preparation of encapsulated porphyrin hybrid materials or as catalysts for synthesis of porphyrins in solution is discussed. Encapsulated porphyrin yields are dependent on both the acidity…
A new super-supertetrahedral cluster, resembling a coreless supertetrahedral T6 cluster, was made as a tin oxyselenide by integrating hard and soft Lewis bases (O(2-) and Se(2-)) into the tetravalent system. Its hierarchical architecture, built from supertetrahedral T3-[Sn10O4Se20] and Sn2Se6 clusters, represents a ne…
Two new alternating μ1,1- and μ1,3-azido bridged chains, [Cu(N3)2(mtn)]n (1) and [Ni(N3)2(mtn)]n (2) where mtn = N-methyl-1,3-propanediamine, have been synthesized and characterized by single crystal X-ray diffraction. In both complexes, each metal atom is coordinated to six nitrogen atoms from four azide anions and o…
The vibration behavior of piezoelectric microbeams is studied on the basis of the modified couple stress theory. The governing equations of motion and boundary conditions for the Euler-Bernoulli and Timoshenko beam models are derived using Hamilton’s principle. By the exact solution of the governing equations, an expr…
sequence independent of the L- or H-chains. A similar tendency was observed for the high migration activities of the endothelial cells in vitro and also the longer migration distance of the endothelial cell from the anastomotic part of rat abdominal aorta in vivo when this recombinant silk fibroin was used as a coatin…
Wood-based microhaired superhydrophobic and underwater superoleophobic surfaces capable of effective oil/water mixtures separation are fabricated using a scalable replication technique.
The length of porous FeV <sub>x</sub> O <sub>y</sub> 1-D nanostructures could be tuned from several micrometers to several millimeters.
The study is focused on the water diffusion phenomenon through the Raffia vinifera fibre from the stem. The knowledge on the behavior of those fibres in presence of liquid during the realization of biocomposite, is necessary. The parameters like percentage of water gain at the point of saturation, modelling of the kin…
Here we have shown that it is possible to modulate hydrophobic and hydrophilic interactions to further adjust the supramolecular helicity by changing the length of an alkyl chain. These modulated supramolecular interactions have been translated to and observed in electrical conductivity, and provide a new pathway to c…
In this study, silk nanofibres were prepared by electrospinning from silk fibroin in a mixture of formic acid and calcium chloride. A needle and a rotating cylinder were used as fibre generators in the spinning process. The influences of the spinning electrode and spinning parameters (silk concentration and applied vo…
Two meso-tetraphenylporphyrin (H2TPP) derivatives with different central metal ions, namely ZnTPP, CuTPP, were synthesized, and characterized by a series of spectroscopic methods. Their self-assembly behaviors in mixed solvents without surfactant were systematically investigated. The morphology of the thus produced na…
We report on the performance of composite nerve grafts with an inner 3D multichannel porous chitosan core and an outer electrospun polycaprolactone shell. The inner chitosan core provided multiple guidance channels for regrowing axons. To analyze the in vivo properties of the bare chitosan cores, we separately implant…
We study the dynamics of ring polymers confined to diffuse in a background gel at low concentrations. We do this in order to probe the inter-play between topology and dynamics in ring polymers. We develop an algorithm that takes into account the possibility that the rings hinder their own motion by passing through the…
A composite electrode was manufactured by pyrolysis of Red Algae ( <italic>Polysiphonia fucoides</italic> ) covered by diatoms ( <italic>Diatomophyceae</italic> ).
A novel bifunctional substrate derived from well-aligned Ag2S microrod arrays was obtained via a facile and cost-effective solvothermal process rapidly within 1 h. It demonstrates great activity for both SERS detection and photocatalytic degradation of organic dyes, and thus holds great potential for environmental mon…
