The hydrogen bonding effects that were produced from interaction of membrane lipid dipalmitoylphosphatidyl-ethanolamine (DPPE) with 1-5 water molecules, has been theoretically  investigated through the quantum mechanical calculations at the Hartree-F... see more

The effect of the polarity of the environment on the conformation zwitterionic membrane dilauroyl phosphatidylcholine (DLPC) has been investigated with calculation at the Hatree-Fock level using the 6-31G* basis set with Onsager continuum solvation model.... see more

The research of Computer Asissted Instruction with animation and simulation was used to misconception remediation of atomic orbital, molecular orbital, and hibridiziation concepts. The applicated instruction model was focused on concept approach with macr... see more

The aim of the present paper is to analyze the problem of the relationship between chemistry and physics, by focusing on the widely discussed case of the atomic orbitals. We will begin by remembering the difference between the physical and the chemical in... see more

Recently, substituted 1,8-dioxodecahydroacridine derivatives have been investigated and found to possess a wide variety of biological and phar­macological activities. Two of these biologically relevant N-heterocyclic scaf­folds, 2-(9-(4-me­th­oxyphenyl)-3... see more

Complexation of quinoline aza oxa this 17-crown-6 (L) with some metal cations (K+, Na+, Li+, Mg2+) was studied through computational methods. Hartree-Fock method was employed to identify structure and thermodynamical binding constant of crown and metal io... see more

With this work, we try to answer 3 fundamental questions that have plagued mathematicians and physicists for several decades. As known, the spontaneous symmetry breaking (SSB) and the Brout-Englert-Higgs Mechanism (BEH-M) solved the Yang-Mills Mass Gap Pr... see more

Using ab initio methods of quantum chemistry the structure and spectral properties for molecular complexes, which were formed by monomer of phenilon ?-2 chain, including some intra- and intermolecular hydrogen bonding effects as well as electrostatic inte... see more

As the largest palm oil producer in the world, Indonesia has a promising potential to produce green fuel through the Fluid Catalytic Cracking (FCC) process. A novel FCC configuration, FCC Proto X 3, which combines a riser reactor and downer reactor i... see more
