The dynamics of the one-dimensional spin-1 ∕ 2 isotropic heisenberg model with dzyaloshinskii–moriya (dm) interaction in the presence of a random magnetic field perpendicular to the dm axis (a transverse field) is investigated by using the method of recurrence relations.
May 1, 2019 the 2d images were integrated into 1d patterns using dioptas (prescher and prakapenka 2015) and refined using the pdindexer software (seto.
The recent developments for one-dimensional aggregates started in 1988 with the disclosure of the double hydrogen-bonded polymeric assembly by wuest 13 although this first example was only a polymer in the crystalline state, similar to the crystals of terephthalic acid, it showed the option to design a polymeric array by multiple hydrogen bonds.
The analysis of one-dimensional stacking disorder was performed by fitting the observed xrpd pattern with a calculated intensity curve generated by diffax. The disorder model was investigated by taking into account a probability matrix for the occurrence of od layer sequences.
Assuming that the carbonate stoichiometrically replaces oxygen, the composition of the low-temperature α-modification, obtained by slow cooling from 1100 °c, corresponds to ba4nb2o8.
In condensed matter physics, a bose–einstein condensate (bec) is a state of matter (also called the fifth state of matter) which is typically formed when a gas of bosons at low densities is cooled to temperatures very close to absolute zero (-273.
Energy is one of the most important issues facing the 21st century. [1-4] driven by the accelerating demand worldwide for energy, especially for portable devices, electric and hybrid electric vehicles (evs and hevs), and the dwindling supplies of fossil‐based energy, energy storage devices are urgently in demand.
X-ray crystallography (xrc) is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident x-rays to diffract into many specific directions.
Crystallization is the process of atoms or molecules forming an organized solid via nucleation and growth. Being intrinsically stochastic, the research at an atomistic level has been a huge experimental challenge. We report herein in situ detection of a crystal nucleus forming during nucleation/growth of a nacl nanocrystal, as video recorded in the interior of a vibrating conical carbon.
One-dimensional models these models say a problem is caused by one thing. This is true for one disorder: huntington's chorea, a disease that first shows signs in dance-like movements of the limbs, goes on to psychosis and ends with an early death.
Investigations by x-ray diffraction and ir-spectroscopy indicated a strong one-dimensional stacking disorder of (alsio 4)-layers in its crystal structure influenced by the enclathration of carbonate.
State that the structural features of their original paper are valid in context. They emphasize that this is the first time the sbo 4 f group has been used as a new bifunctional group to design nonlinear optical materials, and not as a structural group, and that this is the first example of a nonlinear material with a cairo pentagonal tiling.
The filtered mwnt was then stirred in 1mhcl/h2o(12 ml) for an additional hour and with poly(bisphenol-a-carbonate) (25 mg–2 g) (aldrich) in ch2cl2 solution.
The entropy of a substance is influenced by structure of the particles (atoms or molecules) that comprise the substance. With regard to atomic substances, heavier atoms possess greater entropy at a given temperature than lighter atoms, which is a consequence of the relation between a particle’s mass and the spacing of quantized translational energy levels (which is a topic beyond the scope.

Low crystalline cosx was fabricated by anion-exchange of 2-dimensional (2d) cobalt carbonate hydroxide. (coch) using sulfides have emerged as one of prominent candidates for scs due capability due to the disorder structures.

Thin films of germanium are cycled in a half-cell configuration with lithium metal foil as counter/reference electrode, with 1m lipf 6 in ethylene carbonate, diethyl carbonate, dimethyl carbonate solution (1:1:1, wt%) as electrolyte. Real-time stress evolution in the germanium thin-film electrodes during electrochemical lithiation/ delithiation.
Calcium carbonate and its acc is one of six known forms of calcium carbonate, ex- cluding high-temperature single calcite crystal of millimeter dimensions is obtained.
Many recently published works describe the order-disorder cation distribution in the tetrahedral and octahedral sheets and the crystal defects in the layer stacks. Related to the periodic bond chains (pbcs) theory, these data suggest that the size and the shape of clay crystallites could depend on the amount of crystal defects in the three axes.
Using monochromatic model involves disorder of one of the pb positions.
The sn ii species then react with co 2 to form the surface-bound sn carbonates, as evidenced by their in situ atr-ir. Tin carbonate undergoes the necessary transfers of two electrons and a proton to form formate, which quickly desorbed, and the surface returns to the sn ii oxyhydroxide surface.
Amorphous calcium carbonate (acc) is the amorphous and least stable polymorph of calcium but while acc is the first product to precipitate, it rapidly transforms into one of the more stable polymorphs within seconds.

One-dimensional solids atoms of some elements such as sulfur and selenium can bond together in long chains of indefinite length, thus forming polymeric, amorphous solids. The most well known of these is the amorphous plastic sulfur formed when molten sulfur is cooled rapidly by pouring it into water.

Abstract the reservoir temperature of the waters in the low temperature carbonate-evaporitic geothermal system of arnedillo has been estimated by using two different techniques: 1) chemical geothermometers and 2) geothermometrical modelling. By combining the results of both techniques a reliable range of temperature of 90 ± 20°c has been proposed for the waters in the reservoir.
1,5‐disubstituted 1,2,3‐triazoles can be used to mimic disulfide bonds and overcome their redox instability. Craik, and co‐workers show in their communication on page 11273, the triazole motif can be incorporated into backbone cyclic peptides based on the sunflower trypsin inhibitor‐1 scaffold.
Currently, one-dimensional (1d) nanostructures, such as nanofibers (nfs), nanorods, nanotubes, nanowhiskers, and nanowires, have great potential applications in fields of optics, mechanics, electricity and catalysis due to their unique properties, such as large specific surface area, nano-size effect and interface effect, short ionic transport lengths, directional transmission.

A diverse microbial consortium rather than a single microorganism is commonly involved in carbonate and phosphate precipitation in natural environments [5,9,25,26]. In this respect, saline lakes and their halophilic microorganisms give an opportunity to study effect of abiotic factors on bacterial nanoglobules formation and biomineralization processes under natural conditions.
