Significance A hyperbranched mechanically interlocked polymer was prepared by polyesterification of a dynamic trifunctional AB 2 pseudorotaxane monomer.
Significance A series of metal cage complexes 1 , formed by the [2+3]-type cocondensation of a π-extended boronic acid and dioxime is reported. The materials formed following electrochemical polymerization are shown to retain the redox properties of the coordinated metal. Furthermore, consecutive electropolymerization…

Significance Reported is the indium trichloride mediated multicomponent synthesis of highly substituted pyrroles. The reaction proceeds in one pot and does not require the exclusion of air or moisture. A number of catalysts were investigated and indium trichloride was shown to be superior, although a mixture of Ag(OTf…
Significance The authors describe the synthesis, X-ray crystal structure, and physical property characteristics of teranthene 1 . The stabilized polycyclic aromatic hydrocarbon (PAH) was shown to possess prominent biradical character in the ground state.
A novel technique of spectroscopic imaging using a near-infrared (NIR) laser sheet beam was developed for visualization of liquid water in a proton-exchange membrane (PEM) sandwiched between two opaque electrodes set in a polymer electrolyte fuel cell (PEFC). In-plane two-dimensional distribution of water in the thin…
Les cel·les solars sensitivitzades amb un colorant son un tipus de dispositius que han cridat molt l'atencio com a una alternativa menys costosa economicament a les actuals cel·les solars comercials de silici. Aquesta tesi s'ha focalitzat en la determinacio de la influencia de l'estructura molecular dels colorants i l…
Un pont de dihidrogen (dihydrogen bond,DHB) es un tipus de pont d'hidrogen atipic que s'estableix entre un hidrur metal·lic i un donador de protons com un grup OH o NH. Els ponts de dihidrogen son claus en les caracteristiques geometriques i altres propietats de compostos que en presenten tan de molecules petites com…

RESUMONeste trabalho filmes finos de silício amorfo hidrogenado (a-Si:H) foram depositados no reator magnetron sputtering do laboratório de sistemas integráveis (LSI), a temperaturas menores que 100 °C, pela introdução do gás hidrogênio junto com o de argônio para pulveriz…
Development of the Monte Carlo method for the calculation of theinteractions and electric transport in the ternary semiconductorsIn this paper; we show the interest of the heterostructures initially, then the need for using a numerical method and in particular that of Monte Carlo, to calculate electric transport in th…
A rollable transparent glass-fabric reinforced composite film (GFRHybrimer) with potential for use as a substrate in flexible devices is reported on p. 4510 by Byeong-Soo Bae and co-workers. The GFRHybrimer film is fabricated by impregnating woven glass-fabric with a photocurable sol-gel hybrid material (Hybrimer). Th…
In this paper the blast resistance of cracked steel structures repaired with fibre-reinforced polymer (FRP) composite patch are investigated. The switch box which has been subjected to blast loading is chosen for a detailed study. For impulsively loaded structures, the structural damage and response depends on the imp…
Abstract : Fluorinated polyhedral oligomeric silsesquioxanes (F-POSS), a subclass of POSS, were recently synthesized and have proven to be an excellent low-surface energy material for superhydrophobic and oleophobic surfaces. These F-POSS compounds consist of a silicon-oxide core with a periphery of long chain fluorin…
Extraction of complex (∝1P2W17O61Fe)7- by liquid surfactantmembrane The extraction of a Dawson-type heteropolyanion (∝1P2W17O61Fe) 7- was carried out by liquid surfactant membrane using (SPAN80) as surfactantand (TIBA) as extractant, internal phase used (NH4)2CO3. The extraction efficiency is 90 %. Then in order to re…
Abstract Functional organic field‐effect transistors (OFETs) have attracted increasing attention in the past few years due to their wide variety of potential applications. Research on functional OFETs underpins future advances in organic electronics. In this review, different types of functional OFETs including organi…
Y2O3:5%Er nanocrystalline powder was prepared by low temperature combustion method. The crystal structure and morphology were analyzed by means of XRD and HRTEM. The resultant powders were sintered into translucent ceramics at 1570°C in vacuum for 6 hours. The micrograph of unpolished surface and fracture surfaces sho…
By using a simulated annealing approach, Monte Carlo and molecular-dynamics techniques we have studied static and dynamic behavior of the classical two-dimensional anisotropic Heisenberg model. We have obtained numerically that the vortex developed in such a model exhibit two different behaviors depending if the value…
Biochemistry![Figure][1] CREDIT: MIDORI Forests contain a lot of carbon, and much of that carbon is used to make the structural polymer cellulose. Like other biopolymers, cellulose is synthesized inside cells, yet it must be extruded across cell membranes as individual chains that are wound together, first into smalle…
Because of its own structure's limitation, the beam divergence angle of the semiconductor laser is very large. In the fastaxis direction, the beam plays good quality and can be collimated less than 1° by using cylindrical micro-lens. However, in the slow-axis direction, the beam quality is too poor to be collimated to…
