We present a review of the theoretical and experimental evidence for the peculiar properties of comb copolymers, demonstrating the uniqueness of these materials among other polymer architectures. These special properties include an increase in stiffness upon increasing side-chain length, the spontaneous curvature of adsorbed combs, rod-globule transition, and specific intramolecular self-assemb...

High photoconductivity of p-type nanofibers fabricated from a reducing tetracyclic macromolecule was achieved though a simple photodoping process under ambient conditions, which, together with the intrinsic high surface area and porosity of the nanofibers when deposited on a substrate, enables application in electrical vapor sensing of organic amines.

Electrostatic potential as well as the local volume charge density are computed for a macromolecule by solving the Poisson-Boltzmann equation (PBE) using the finite element method (FEM). As a verification, our numerical results for a one dimensional PBE, which corresponds to an infinite-length macromolecule, are compared with the existing analytical solution and good agreement is found. As a ma...

BACKGROUND AND PURPOSE We sought to measure the temporal evolution and spatial distribution of lesion macromolecules and small molecules (lactate, N-acetyl compounds, creatine, and choline) in stroke patients by using short echo time in vivo proton MR spectroscopy. METHODS Single-voxel spectra with TE=22 ms were obtained with and without inversion recovery suppression of small-molecule resona...

Conditions have been established for the preparation of spheroplasts of Saccharomyces cerevisiae which are able to increase their net content of protein, ribonucleic acid (RNA), and deoxyribonucleic acid (DNA), several-fold upon incubation in a medium stabilized with 1 m sorbitol. The rate of RNA and protein synthesis in the spheroplasts is nearly the same as that occurring in whole cells incub...
