Two different fluorescent single walled carbon nanotubes (SWNT) were prepd. First by a reaction of oxidized SWNT-K salt with 1,3-bis(9-anthracenylmethyl)imidazolium chloride (bamim)Cl to provide a fluorescent system SWNT-(bamim), via ion exchange and forma ...
The thermally induced hysteretic spin transition (ST) that occurs in the polymeric chain compound Fe(NH(2)trz)(3)(2) (1) above room temperature (T-c(sic) = 347 K, T-c(sic) = 314 K) has been tracked by Fe-57 Mossbauer spectroscopy, SQUID magnetometry ...
Humic substances (HS) play an important role in the reactivity and transport of colloids in natural environments. In particular, the presence of fulvic acids (FA) in natural waters modifies the interactions between inorg. particles and biopolymers and make ...
Experiments and molecular simulations have shown that the hydrophobic mismatch between proteins and membranes contributes significantly to lipid-mediated protein-protein interactions. In this article, we discuss the effect of cholesterol on lipid-mediated ...
In this study, we describe synthesis, characterization, and zipper assembly of yellow p-oligophenyl naphthalenediimide (POP-NDI) donor−acceptor hybrids. Moreover, we disclose, for the first time, results from the functional comparison of zipper and layer-b ...
The state-of-the-art in control of hand prosthetics is far from optimal. The main control interface is represented by surface electromyography (EMG): the activation potentials of the remnants of large muscles of the stump are used in a non-natural way to c ...
Impurities are known to have a significant impact on materials properties. In particular, the presence of impurities can change mechanical properties and stabilize the microstructure by reducing grain growth and recrystallization processes. In the past ato ...
A series of lanthanide complexes [LnClx(bpy)y(H2O)z]Cl3-x(H2O)n(EtOH)m (Ln ) Eu, Gd, Tb; x ) 1, 2; y ) 1, 2; z ) 2-4) with different numbers of 2,2′-bipyridine (bpy), chloride ions, and water molecules in the inner coordination sphere were synthesized and ...
Covalent functionalizations represent a very promising avenue to engineer or manipulate carbon nanotubes. However, in metallic tubes the electrical conductance can drop by several orders of magnitude following functionalization, due to sp(3) rehybridizatio ...
Taking a a turn. Short tripeptides that form stable ß turns in water are remarkably stable against chemical and thermal degradation. Terminal cation-π interactions lead to stabilization of these turns that are formed independently of sequence. ...
