Thomson’s classical analysis ( 1851 , 1854a , 1854b ) of thermoelectricity is cast into a modern form by means of contemporary thermodynamic methods based on the introduction of a free energy depending on strain, electrical charge and temperature. The present analysis identifies the phenomenological coefficients in Th…
Abstract The electromechanical properties of an electro‐active artificial muscle of poly(styrene‐alt‐maleimide)/poly(vinylidene fluoride) with glycerol as a solvent at ultralow frequencies were investigated. Actuated at higher potentials and in the open air, the artificial muscle showed no back‐relaxation, and the def…
Calmodulin (CaM), a Ca(2+)-binding protein, is a well-known regulator of various cellular functions. One of the targets of CaM is metabotropic glutamate receptor 7 (mGluR7), which serves as a low-pass filter for glutamate in the pre-synaptic terminal to regulate neurotransmission. Surface plasmon resonance (SPR), circ…
The photodissociation dynamics of alkali−ammonia clusters in the gas phase have been explored using a combination of photofragmentation spectroscopy and velocity map imaging. Electronic excitation of Li(NH 3 ) 4 to the à 2 T 2 state leads to the production of relatively slow photofragments with a high degree of intern…
The deposition of all buffer and YBCO layers for coated conductors via MOCVD represents one of the lowest possible capital and operational cost approaches to coated conductor manufacturing. Modular design of our prototype MOCVD system allows for either in-line or parallel fabrication of any number of buffer layers and…
Bacterial biofilms constitute an extremely resistant form of bacterial colonization with dire health and economical implications. Towards achieving polymeric composites capable of resisting bacterial adhesion and biofilm formation, we prepared five 2,6-pyridinedicarboxylate-based polyesters employing five different di…
The influence of the spin-Zeeman (SZ) operator in the evaluation of the spin-orbit effect on the nuclear magnetic shielding tensor in the context of the linear response within the elimination of the small component approach is critically discussed. It is shown that such term yields no contribution to the isotropic nuc…
A method of forming limit prediction for sheet metals at high temperatures and under nonproportional loading is presented. The method takes into account the strain-softening behaviors of the material at elevated temperatures. A localized necking criterion based on an isotropic damage-coupled acoustic tensor is develop…
This paper proposes a quench detection method applied to a HTS coil and also discusses the results of tests on an HTS BSCCO wire and an HTS YBCO coil. A series-type thermocouple was fabricated to detect quench, where several thermocouples were welded in series. As the series-type thermocouple has many points of detect…
The electronic structures at the MoO(3)∕Co interface were investigated using synchrotron-based ultraviolet and x-ray photoelectron spectroscopy. It was found that interfacial chemical reactions lead to the reduction of Mo oxidation states and the formation of Co-O bonds. These interfacial chemical reactions also induc…
PURPOSE: This work describes the preparation of new nanocomposites based on lamellar silicates (AAM-alkyl ammonium montmorillonite) obtained by the intercalation of PVP K30 and glyceril monostearate. METHODS: By XRD, TGA and DSC analysis the AAM was characterized and its compactation characteristics, functionality and…
The ability of two complementary molecular modules bearing H-bonding uracilic and 2,6-(diacetylamino)pyridyl moieties to self-assemble and self-organize into submicrometer morphologies has been investigated by means of spectroscopic, thermogravimetric, and microscopic methods. Using uracilic (3)N-BOC-protected modules…
Based on integrative computational hybrid approaches that combined statistical coupling analysis (SCA), molecular dynamics (MD), and normal mode analysis (NMA), evolutionarily coupled residues involved in functionally relevant motion in the adenylate kinase protein family were identified. The hybrids identified four t…
We present here a combined experimental and theoretical determination of single-walled carbon nanotube interaction with a graphene surface. The nanotubes are grown on an atomic force microscope (AFM) tip, and we proceed to retract-approach, as well as perform frequency-modulation experiments on a graphene surface, to…
PREMISE OF THE STUDY: Seven microsatellite loci were characterized for the toxic diatom Pseudo-nitzschia multistriata Takano (Takano) to investigate intraspecific variability and estimate population genetic structure over blooms, seasons, and sexual and vegetative reproduction. METHODS AND RESULTS: Selected microsatel…
In this work, we apply a detailed all-atom model with a transferable knowledge-based potential to study the folding kinetics of Formin-Binding protein, FBP28, which is a canonical three-stranded β-sheet WW domain. Replica exchange Monte Carlo simulations starting from random coils find native-like (Cα RMSD of 2.68 Å)…
In this article the effects induced by exposure of sol-gel thin films to hard X-rays have been studied. Thin films of silica and hybrid organic-inorganic silica have been prepared via dip-coating and the materials were exposed immediately after preparation to an intense source of light of several keV generated by a sy…
The effect of surface roughness on droplet impact is considered. If a surface is sufficiently rough, then models of droplet impact need to be altered to include the possibility of many touchdowns between the fluid and the solid. The subsequent simultaneous motion of several contact points is therefore described. In pa…
In this study, we explored the MS/MS behavior of various synthetic peptides that possess a lysine residue at the N-terminal position. These peptides were designed to mimic peptides produced upon proteolysis by the Lys-N enzyme, a metalloendopeptidase issued from a Japanese fungus Grifola frondosa that was recently inv…
We report a hybrid dye-sensitized solar cell consisting of double titania layers (top and bottom layers) stained with two dyes. A top layer fabricated on a glass was mechanically pressed with a bottom layer fabricated on a glass cloth. The glass cloth acts as a supporter of a porous titania layer as well as a holder o…
