In the manufacture of the thin film for liquid crystal devices, we can often find the situation in which the directors are equilibrated under the constraint that fixes only their polar angles on the film surface. We call this surface constraint the "

We study the evaporation process which causes phase separation using the dissipative particle dynamics. To simulate the evaporation, we modify the method introduced by Yamamoto et al: we exchange the solvent particle with the gas particle not in the

To study the effect of the alkyl tail and the terminal dipole on the stability of the liquid crystalline phase of mesogens, we have carried out molecular dynamics simulations for 1CB(4-methyl-4'-cyanobiphenyl) and 5CB(4-n-pentyl-4'-cyanobiphenyl) by

To examine the relationship between the structural features and the visible absorption spectra of yellow α-acylacetanilide azomethine dyes, we carried out measurements of the visible absorption spectra, X-ray crystal structure analyses, and density

Starting from the united atom model, we construct a coarse-grained model for a flexible polymer chain, in which some successive CH2 atoms are combined into an effective segment. To connect the coarse-grained model with the atomistic model, we propose

In this article, we describe a general-purpose coarse-grained molecular dynamics program COGNAC (COarse Grained molecular dynamics program by NAgoya Cooperation). COGNAC has been developed for general molecular dynamics simulation, especially for coa

We have determined sets of coarse-grained potentials for nCB (4-n-alkyl-4′-cyanobiphenyl) starting from the united atom pair potential of the OPLS force field. As a coarse-grained model, we employed a hybrid Gay-Berne/Lennard-Jones model consisting

We have studied the mechanism for the reaction of p-benzoquinone diimine with phenolate, the model reaction of a key elementary step in oxidative coupling of N,N-dialkyl-p-phenylenediamine with phenolic compounds, using ab initio molecular orbital an

From the viewpoint of noncentrosymmetric molecular arrangement design in crystalline state, which is indispensable to second order nonlinear optical materials, intermolecular hydrogen bond formation of eight 5-benzylidene-2,4-thiazolidinedione deriva

2-Azolyl-5-nitropyridines (the generic name “azoles” is hereafter used for pyrrole, diazoles, and triazoles, and “azolyls” for any substituents derived from them) were examined from the viewpoints of the UV-vis absorption properties, the mole
