Precise Molecular Structures of Cysteine, Cystine, Hydrogen-Bonded Dicysteine, Cysteine Dipeptide, Glutathione and Acetyl Cysteine Based on Additivity of Atomic Radii [PDF]

, 2011
Structures of molecules are usually represented by arbitrary line drawings, ball and stick or space filling models. In recent years, the author found that using the appropriate radii of atoms and ions, bond lengths in inorganic, organic and biomolecules ...

The radical character of the acenes: A density matrix renormalization group study [PDF]

, 2007
We present a detailed investigation of the acene series using high-level wavefunction theory. Our ab-initio Density Matrix Renormalization Group algorithm has enabled us to carry out Complete Active Space calculations on the acenes from napthalene to ...

Constructing covalent organic frameworks in water via dynamic covalent bonding

IUCrJ, 2016
The formation of keto-enamine based crystalline, porous polymers in water is investigated for the first time. Facile access to the Schiff base reaction in water has been exploited to synthesize stable porous structures using the principles of Dynamic ...

Computational modeling to elucidate molecular mechanisms of epigenetic memory

, 2015
How do mammalian cells that share the same genome exist in notably distinct phenotypes, exhibiting differences in morphology, gene expression patterns, and epigenetic chromatin statuses?

Fluctuating Nonlinear Spring Model of Mechanical Deformation of Biological Particles [PDF]

, 2015
We present a new theory for modeling forced indentation spectral lineshapes of biological particles, which considers non-linear Hertzian deformation due to an indenter-particle physical contact and bending deformations of curved beams modeling the ...

Water-stable boroxine structure with dynamic covalent bonds

Nature Communications
Boroxines are significant structures in the production of covalent organic frameworks, anion receptors, self-healing materials, and others. However, their utilization in aqueous media is a formidable task due to hydrolytic instability.
