Abstract Anionically charged fluorescent conjugated polyelectrolytes of poly{[4,7‐(2,1,3‐benzothiadiazole)‐alt‐1,4‐phenylene]‐co‐[2,5‐bis(4‐sulfonatobutoxy)‐alt‐1,4‐phenylene]} (P1) and poly{[4,7‐(bis(thiophen‐2‐yl)benzo‐2,1,3‐thiadiazole)‐alt‐1,4‐phenylene]‐co‐[2,5‐bis(4‐sulfonatobutoxy)‐alt‐1,4‐phenylene]} (P2) were…
Abstract We report the synthesis, micellar structures, and multifunctional sensory properties of new conjugated rod‐coil block copolymers, poly(3‐hexylthiophene)‐block‐poly(2‐(di methylamino)ethylmethacrylate)(P3HT‐b‐PDMAEMA). The new copolymers, synthesized by atom transfer radical polymerization of P3HT macroinitiat…
We report on the development of novel cyano-biphenyl-based thiolate self-assembled monolayers designed to promote homeotropic alignment of calamitic liquid crystals. The molecules developed contain an ortho-nitrobenzyl protected carboxylic acid group that on irradiation by soft UV (365 nm) is cleaved to yield carboxyl…
Combined DFT calculations and UV-vis-NIR, ESR, and SQUID measurements revealed that the ground-state electronic structure of a linear π-conjugated oligomer dication composed of two pyrrole and six or seven thiophene rings and methylthio end-capping units is dominated by a singlet biradical character.
Vacancies and interstitials absorbed at Cu-Nb interfaces are shown to migrate by a multistage process involving the thermally-activated formation, motion, and annihilation of kinks and jogs on interface misfit dislocations. This mechanism, including the energy along the entire migration path, can be described quantita…
Abstract A polythiophene derivative substituted with electron‐rich alkynes as a side chain was synthesized using the Suzuki polycondensation reaction. The electron‐rich alkynes underwent the “click chemistry”‐type quantitative addition reaction with strong acceptor molecules, such as tetracyanoethylene (TCNE) and 7,7,…
BACKGROUND: There is an increasing number of proteins with known structure but unknown function. Determining their function would have a significant impact on understanding diseases and designing new therapeutics. However, experimental protein function determination is expensive and very time-consuming. Computational…
Well defined polymeric nanotubules with diameters less than 100 nm are prepared through the template-assisted layer-by-layer method by controlling the ratio of polymer dimension to pore size. The molecular weight of the polymers, the chain conformation, and the aggregation condition are finely tuned by adjusting the v…
Barium strontium zirconate titanate ((Ba1−xSrx)(ZrxTi1−x)O3; BSZT, x = 0.25 and 0.75) ceramics with a highly crystalline structure were successfully synthesized using the combustion technique, in which urea performed an important role. The effect of calcination (1000–1300 °C) and sintering temperatures (1300–1550 °C)…
Direct ultrasonication of graphite particles dispersed in water, in the presence of a surfactant, is a promising way to produce pristine nanoscale graphene platelets (NGPs) without graphite intercalation or oxidation. We investigate possible exfoliation mechanisms, specifically those involving sodium dodecylbenzenesul…
The inverse problem of scattering is solved for 3D inhomogeneities of the complex permittivity in multilayer media.The proposed solution involves an analysis of the 2D lateral distributions of the scattered field with the imposed condition of the probing field invariability relative to the receiver.A generalization of…
A systematic assessment of theoretical methods applicable to the accurate characterization of catalytic cycles of homogeneous catalysts for H(2) oxidation and evolution is reported. The key elementary steps involve heterolytic cleavage of the H-H bond and formation/cleavage of Ni-H and N-H bonds. In the context of den…
The self-assembly of perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) on graphene with coverage in the range of 0.3−3 monolayers (MLs) is characterized by a DFT-based ab initio calculation method. For α modification mode, with a critical thickness of 1 ML, the growth of PTCDA on graphene follows the Stranski−Kras…
Spinel-structured (Mn,Co) 3 O 4 thin films were reproducibly fabricated by atomic layer deposition (ALD) using Mn(thd) 3, Co(thd) 2, and ozone as precursors. A full control of the cation ratio was achieved in the temperature interval 140−160 °C within which also the growth rate remained constant. Precise control of th…
Infrared attenuated total reflection spectroscopy has been used to study the interaction of DMMP vapor with SiO(2), Al(2)O(3), and AlO(OH) vs relative humidity (RH) and DMMP partial pressure (P/P(0)). For SiO(2) the growth with increasing RH of ice-like and liquid-like layers is seen in agreement with previous work. H…
We report the structural, electrical, and magnetoelectric (ME) properties of cofired ME laminate composites synthesized using tape‐casting approach. Compositions corresponding to 0.2Pb(Zn 1/3 Nb 2/3 )–0.8Pb(Zr 0.5 Ti 0.5 )O 3 [PZNT] and (Ni 0.6 Cu 0.2 Zn 0.2 ) Fe 2 O 3 [NCZF] were used as piezoelectric and magnetostri…
The high carrier mobility of graphene makes it an attractive candidate for future electronic device applications.(1) In SiO2/Si-supported graphene devices, the mobility typically varies from 2000 to ∼2,0000 cm(2) V(-1) s(-1).(2) By removing SiO2,(3,4) much higher mobility (2 × 10(5) cm(2) V(-1) s(-1) in the latter) ha…
A biodegradable substrate with a regular array of nanopillars fabricated by electron-beam lithography and hot embossing is used to address the mechanisms of nanotopographical control of cell behavior. Two different cell lines cultured on the nanopillars show striking differences in cell coverage. These changes are top…
The aim of this work is to design highly sensitive guided mode resonance (GMR) sensors for the visible spectral range providing maximum spectral shift of the resonance leaky mode with a change of the refractive index. The GMR sensor consists of a fused silica linear grating coated with dielectric materials by atomic l…
