Dielectric measurements have been made on single-crystals of mica-type layer silicates (vermiculites) in the frequency range between 30 Hz and 10 MHz. The migration of K⁺-and NH₄⁺-interlayer cations by free cation sites causes a low-frequency relaxation. It is interpreted by the orientation of large dipoles they form…

Binary GeₓS₁₀₀–ₓ glasses reveal a richness of elastic and chemical phase transitions driven by network topology. With increasing Ge content (x), well-defined rigidity at xc(1) = 19.3(5)% and a stress transition at xc(2) = 24.9(5)% are observed in Raman scattering. In modulated DSC measurements, the nonreversing enthal…

The most probable conformation of the isomeric thienylpyrroles has been investigated using the HOFFMANN’S variant of the Extended HUCKEL Theory. Planar syn conformation is predicted slightly more stable than anti for 2,2′-, 2,3′-, and 3,2′-isomers, while the 3,3′-isomer is predicted to have anti conformation slightly…

A basic understanding of thermal properties of polymers is of fundamental importance for the development of advanced polymers. However, up to now, mainly bulk properties have been investigated. To characterize local softening processes in polymers, a local thermal analysis (LTA) technique is applied as an add-on to a…

The solvent extraction of an ionizable solute (H₃PO₄) from water into a water-in-oil microemulsion, and subsequent organic phase splitting (known as third phase formation), has been recast as a critical phenomenon by linking system structure to solute concentration via a critical exponent. The transuranic extraction (…

An integrated multi-walled carbon nanotube (MWCNT)–carbon fiber (CF) hybrid material has been fabricated by electrophoretic deposition of acid-functionalized MWCNTs on CF surface followed by soaking in a 10% solution of petroleum pitch in toluene, followed by pyrolysis in a nitrogen atmosphere. It has been revealed th…

Triphenyltinchloride and -acetate, the corresponding lead compounds, and Tribenzyltinchloride are effective electron scavengers in γ-irradiated glasses from 2-Methyltetrahydrofuran at 77°K. The reaction with the electrons leads to the formation of tin- and leadradicals via dissociative electron capture. Only in the ca…

A new coarse-grained force field is developed for polyethylene glycol (PEG) in water. The force field is based on the MARTINI model but with the big multipole water (BMW) model for the solvent. The polymer force field is reparameterized using the MARTINI protocol. The new force field removes the ring-like conformation…

The SO₂-insertion into the tin-carbon bond of mixed tetraorganostannanes, R₃SnR’ (R = alkyl, R’ = aryl, and vice versa), is determined by the nucleophilicity of the organic residue attached to metal, the ease of cleavage decreasing in the order aryl > alkenyl ⪢ alkyl. As has been proved by chemical and spectroscopic m…

Dynamics of water confined in ∼5 A diameter channels of beryl and cordierite single crystals were studied by using inelastic (INS) and quasielastic (QENS) neutron scattering. The INS spectra for both samples were similar and showed that there are no hydrogen bonds acting on water molecule, which experiences strong ani…

Background—Remote ischemic preconditioning may result in reduction in infarct size during percutaneous coronary intervention (PCI). It is unclear whether remote ischemic postconditioning (RIPost) will reduce the incidence of myocardial injury after PCI, and whether ischemic conditioning of a larger remote organ (thigh…
