The ability of polymers displaying lower critical solution temperatures (LCSTs) to mediate bioadsorptive processes was assessed. Three carboxyl-terminated polymers P1 − 3 with LCSTs respectively of 20, 32, and 42 °C were prepared by free-radical polymerization of N -isopropylacrylamide with and without comonomers acry…

The deposition of Cu at room temperature on a Cr 2 O 3 (0001) substrate is studied by x-ray photoelectron spectroscopy, ultraviolet photoelectron spectroscopy and low-energy-electron diffraction. The results indicate that at RT Cu is highly dispersed on the substrate at initial deposition. X-ray induced Auger spectra,…
Maltose-binding protein (MBP or MalE) of Escherichia coli is the periplasmic receptor of the maltose transport system. MalE31, a defective folding mutant of MalE carrying sequence changes Gly 32-->Asp and Ile 33-->Pro, is either degraded or forms inclusion bodies following its export to the periplasmic compartment. We…
Abstract Two new paramagnetic transition metal complexes that contain the bridging ligand azo‐2,2′‐bipyridine (abpy) have been prepared and characterized by X‐ray crystallography and magnetic susceptibility measurements. The compound [Ni 2 (μ‐abpy)(CH 3 CN) 2 (NO 3 ) 4 ]·2CH 3 CN ( 1 ·2CH 3 CN) crystallizes in the tri…
Abstract Reaction of Ni(ClO 4 ) 2 ·6H 2 O with bis(3‐aminopropyl)amine (dpt) and ammonium thiocyanate produces the novel thiocyanato‐bridged nickel( II ) compound [Ni(μ‐NCS)(dpt)(NCS)] 2 [Ni(μ‐NCS)(dpt)(NCS)] 4 , which has been structurally characterised. The structure determination reveals that there are two differen…
Abstract The donor‐acceptor complexes with a vinylogue monohydro sesquifulvalene and sesquifulvalene backbone of the type [(η 5 ‐C 5 H 5 )Ru{µ‐(η 5 ‐C 5 H 4 )C 2 H 2 (η 6 ‐C 7 H 7 )}ML](PF 6 ) n [ n = 0: ML = none ( 1 ), Cr(CO) 3 ( 2 ); n = 1: ML = Ru(η 5 ‐C 5 H 5 ) ( 3a ), Ru(η 5 ‐C 5 Me 5 ) ( 3b )] and [(η 5 ‐C 5 H…
A number of experimental and computational studies of materials have shown that transport rates in domain walls may significantly differ from those in the bulk. One possible explanation for enhanced transport in a domain wall is that the domain wall is elastically soft with respect to the bulk. We investigate the soft…
Lysine, poly-lysine and lysozyme were successfully intercalated in the MnPS3 layered phases. Intercalates were characterised by elemental and thermogravimetric analysis, and X-ray powder diffraction. Biomolecules conformation between the layers appears to result from the optimisation of the host–guest interactions. Mo…
Abstract Stepwise cross‐coupling reactions between functionalized metallo synthons and bipyridine‐ or terpyridine‐based building blocks afford novel photoactive, hybrid complexes bearing multiple chromophores that function separately or cooperatively according to the nature of the coordinated metal cations. (© Wiley‐V…
The deformation effects in electronic spectra of the ternary layered semiconductors TlGaS 2 , TlGaSe 2 and TlInS 2 are considered. It is shown that the influence of hydrostatic pressure, thermal expansion and variation of composition in solid solutions on the band gap of the crystals investigated can be described in t…
Silver nanoparticles capped with organoisocyanide and host or guest molecules are a very effective molecular sensing/recognition mediator via surface-enhanced Raman spectroscopy.
The crystal structure of compositionally homogeneous, nanocrystalline ZrO2–10, 30, 50, 70 and 90 mol% CeO2 powders synthesised by a pH-controlled nitrate–glycine gel-combustion process has been studied by X-ray diffraction and Raman spectroscopy. All the powders with a CeO2 content up to 70 mol% exhibited the tetragon…

A series of chromophores with high second-order nonlinearities has been synthesized; the chromphores consist of triarylamine or dialkylarylamine donors linked by a conformationally locked polyene bridge to a dicyanomethylidene acceptor. The use of bridges of this type, combined with the replacement of dialkylarylamine…
The rise of antibiotic resistance as a public health concern has led to increased interest in studying the ways in which bacteria avoid the effects of antibiotics. Enzymatic inactivation by several families of enzymes has been observed to be the predominant mechanism of resistance to aminoglycoside antibiotics such as…
Calcium carbonate was grown by diffusion of gaseous carbon dioxide into aqueous calcium chloride–alcohol solutions and the relationship between the alcohol additive and the growing crystal was investigated. There was no evidence that crystal growth was controlled through any specific molecular interaction between the…
We present theoretical and dynamic Monte Carlo simulation results for the mobility and microscopic structure of 1+1-dimensional Ising interfaces moving far from equilibrium in an applied field under a single-spin-flip ``soft'' stochastic dynamic. The soft dynamic is characterized by the property that the effects of ch…
The connections between the anti-shielding effect, negative absolute temperature and superluminal light propagation in both the instantaneously reversed electric field and the left-handed media are considered in the present paper. The instantaneous inversion of the exterior electric field may cause the electric dipole…
Building on the success of the first edition Fuel Cell Systems Explained presents a balanced introduction to this growing area. In summary, an altogether satisfying book that puts within its covers the academic tools necessary for explaining fuel cell systems on a multidisciplinary basis. Power Engineering Journal. An…
