Molar mass estimate of dark matter from the dark mass distribution measurements [PDF]

open access: greenPhysical Review D, 2003
We study the distribution of dark matter versus visible matter using a set of data obtained from strong gravitational lensing in the galaxy cluster CL0024+1654 and another set of data inferred from the universal rotation curves in spiral galaxies. The important feature of these two dramatically different observations is that the mass density profile of

Renaturation behavior of xanthan with high molar mass and wide molar mass distribution [PDF]

open access: bronzePolymer Journal, 2016
Light scattering and viscosity measurements were carried out for thermally renatured xanthan samples with various molar masses and molar mass distributions. The increases in the molar mass, radius of gyration, and intrinsic viscosity of a xanthan sample with high molar mass and wide molar mass distribution upon renaturation were smaller than in xanthan

Molar masses and molar mass distributions of commercial regenerated cellulose materials and softwood dissolving pulp determined by SEC/MALLS [PDF]

open access: hybridCellulose, 2023
AbstractThe molar masses and molar mass distributions of three commercial regenerated cellulose samples, viscose rayon, Tencel, and Bemliese (or cuprammonium nonwoven), have been determined by dissolution in 8% (w/w) lithium chloride/N,N-dimethylacetamide (LiCl/DMAc) and subsequent size-exclusion chromatography with multi-angle laser-light scattering ...

Catalytic flow with a coupled Finite Difference -- Lattice Boltzmann scheme [PDF]

open access: yes, 2020
Many catalyst devices employ flow through porous structures, which leads to a complex macroscopic mass and heat transport. To unravel the detailed dynamics of the reactive gas flow, we present an all-encompassing model, consisting of thermal lattice ...

Using Triethylborane to Manipulate Reactivity Ratios in Epoxide-Anhydride Copolymerization: Application to the Synthesis of Polyethers with Degradable Ester Functions

open access: yesMolecules, 2022
The anionic ring-opening copolymerization (ROCOP) of epoxides, namely of ethylene oxide (EO), with anhydrides (AH) generally produces strictly alternating copolymers.

Quantification of identical and unique segments in ethylene-propylene copolymers using two dimensional liquid chromatography with infra-red detection [PDF]

open access: yesPolyolefins Journal, 2016
Hyphenating High Temperature High Performance Liquid Chromatography (HT-HPLC) with High Temperature Size Exclusion Chromatography (HT-SEC) (High Temperature Two Dimensional Liquid Chromatography (HT-HPLC x HT-SEC or HT 2D-LC)) leads to an isocratic ...

Multi angle light scattering as a process analytical technology tool for real-time monitoring of molar mass of protein-polysaccharide conjugate fractions

open access: yesJournal of Chromatography Open, 2022
Current polysaccharide conjugate vaccine manufacturing process involves conjugation of polysaccharide with protein followed by separation/purification of the conjugate from reaction components and free polysaccharide/protein, by preparative Size ...

Molar mass and solution conformation of branched alpha(1 - 4), alpha(1 - 6) Glucans. Part I: Glycogens in water [PDF]

open access: yes, 2008
Solution molar masses and conformations of glycogens from different sources (rabbit, oyster, mussel and bovine) were analysed using sedimentation velocity in the analytical ultracentrifuge, size-exclusion chromatography coupled to multi-angle laser light

Sensitivities of the absorptive partitioning model of secondary organic aerosol formation to the inclusion of water [PDF]

open access: yes, 2008
The predicted distribution of semi-volatile organic components between the gaseous and condensed phase as a function of ambient relative humidity and the specific form of the partitioning model used has been investigated.
