Two-dimensional (2D) nanosheets have gained its interest since 2004, when Dr. Andre Geim and Dr. Konstantin Novoselov isolated free-standing single layer of graphene (Novoselov et al. 2005). is discovery challenged the theoretical views on 2D materials and showcased the research community about the stability and poten…
Layered metal hydroxides (Braterman 2004, Rives 2006, Carillo and Griego 2012, Wang and O’Hare 2012), consisting of metal-hydroxyl host layers (sheets, slabs) and/or charge-balancing anions in the interlayer galleries, aord a large variety of functionality and hybrid possibility for potential applications as anion exc…
Ethylene is the most widely produced organic commodity in chemical industry with an annual global demand of over 140 × 106 tons and a growth rate of 3.5% per year [1]. It is mainly used as a monomer for making polyethylene. Ethylene could also potentially serve to make high octane number fuels via oligomerization in t…
During the past decades, nanostructured materials have been widely investigated for a huge spectrum of advanced technological applications, ranging from microelectronics to solar cells (Narayan 2012; Ferric et al. 2013; Kujawa and Winnik 2013). In recent years, multifunctional nanoparticle systems have been developed…
The effect of diffusion resistance in porous solid catalysts on reaction rate during periodic cycling of CO concentration is shown for CO oxidation over Pt/Al 2 O 3 by numerical simulation. At some cycling frequencies, the average reaction rate during cycling is higher than the steady-state rate at the mean CO concent…
Abstract A coordination polymer constructed from the ligand 2, 2′‐bipyridine‐5, 5′‐carboxylate (Bpydc) with hybrid functional groups and the co‐ligand SO42– was synthesized and structurally characterized by single‐crystal X‐ray diffraction. It shows an intriguing structure of parallel infinite Mn–SO4 double chains res…
We report on an improvement of the open circuit voltage over 0.8 V, together with decent fill factor and large short circuit current, through the incorporation of ester-functionalized single wall carbon nanotubes in a poly(3-hexylthiophene): 1-(3-methoxycarbonyl) propyl-1-phenyl[6,6]C61 bulk heterojunction solar cell.…
Polystyrene (PS) is a common substrate material for protein adsorption on biosensors and bioassays. By employing a quartz crystal microbalance (QCM) technique, we studied the kinetics and thermodynamics of anti-HBeAg adsorption on this substrate in situ. First, a thin PS film was deposited on the interface between the…
The previous two papers demonstrate some of the remarkable possibilities open to materials researchers using synchrotron techniques. From an experimental standpoint, the insight into critical, and previously impenetrable, deformation and transformation mechanisms is second to none. The in situ
An investigation was made into the fatigue properties of L485MB (X70) pipeline steel after 13 yr of exploitation as a crude oil pipeline material. Fatigue tests in zero-to-tension loading were carried out (i) in air, (ii) in crude oil, (iii) in a mixture of crude oil with rainwater, and (iv) in water separated from th…
To understand the structure of cellulose, we searched for the global minimum potential energy of cellobiose, a basic structural unit of cellulose, in vacuum and water. We used the Low‐MODe (LMOD) optimization method in the Ambertools1.5 package with a GLYCAM_06 force field. The generalized Born model proposed by Hawki…
Abstract A 1 % w/w alumina‐supported gold catalyst is described that is prepared from the impregnation of alumina with a solution of ammonium tetraazidoaurate(III), NH4[Au(N3)4]. Decomposition of the azide precursor leads to a residue‐free catalyst comprised of well‐dispersed gold particles. This novel material is tes…
The unique rolled graphene structure of carbon nanotubes (CNTs) provides these materials with various properties that could be useful in their application as catalyst supports. For example, properties of CNTs that are of interest in catalyst supports include their good electrical conductivity, excellent mechanical str…

Boron nitride is an inorganic compound with a chemical formula BN, consisting of equal numbers of boron and nitrogen atoms. BN exists in various crystalline forms; among them, the hexagonal form is the most stable and softest. Boron nitride nanotubes (BNNTs) can be seen as a rolled graphite-like BN sheet, in a fashion…
Boron nitride nanosheets (BNNSs) are an exemplary member of the graphene-analogous 2D nanomaterial family (Golberg et al. 2010, Lin 2012a, Lu et al. 2012, Pakdel et al. 2012, Song et al. 2013). However, BNNSs had not captured much interest from scientists until graphene was exfoliated from graphite in 2004 by Novoselo…
Boron nitride nanotube (BNNT) is a potential reinforcement for structural composites owing to its (1) excellent elastic modulus (750-1200 GPa; Chopra and Zetll 1998, Suryavanshi 2004), (2) tensile strength (up to 61 GPa; Arenal 2011), (3) high bending exibility (Golberg 2007), (4) high fracture strain (Ghassemi 2011),…
This contribution deals with the interaction of cyanide solutions with two types of double-layer structures. A 0.1 M KCN methanol solution, one of the very strong alkaline solutions, was used for t...
Abstract Extensively conjugated tetrathiafulvalene (TTF) derivatives substituted with a TTF-fused 1,4-dithiafulven-6-yl group 4 have been synthesized. Theoretical calculation and X-ray crystal structure analysis of 4a demonstrated that the conformation A, in which the two TTF units are linearly oriented, is slightly m…
Abstract Nanostructures of porous carbon materials were controlled by a soft-template method for expanding their applications. When 2,6-dihydropyridine hydrochloride, a nitrogen-containing compound, was used as a carbon precursor in addition to resorcinol, larger pores over 50 nm appeared besides mesopores. The condit…
