Molecular weight may be calculated from viscosity data (ASTM D2502). The test method requires viscosity data from different temperatures, typically at 37.8°C and 98.9°C (100 and 210°F. The method is generally applicable to a variety of crude oil fraction and products but the number is an...
Molecular Weight The molecular weight of a polymer is of prime importance in the polymer’s synthesis and application. Chemists usually use the term molecular weight to describe the size of a molecule. The more accurate term is molar mass, usually in units of g mol-1. The interesting and ...
Molecular weight of chitosan can be determined by different techniques such as Gel Permeation Chromatography (GPC), Static Light Scattering (SLS) and intrinsic viscosity measurement. Determination of molecular weight by intrinsic viscosity measurement is a simple method for characterization of chitosan. Dif...
The Kazuhei equal molecular weight is 700 or lessPROBLEM TO BE SOLVED: To provide a high performance rubber composition by using a plasticizer derived from an other material than a petroleum resource, and a pneumatic tire by using the same. SOLUTION: The rubber composition comprises a rubber ...
- Molecular mass (molecular weight): The mass of one molecule of a substance, expressed in unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) - Molar mass (molar weight): The mass of one mole of a substance, expressed in grams per mole (...
The set is based on the ZINC Clean Leads collection. It contains 4,591,276 molecules in total, filtered by molecular weight in the range from 250 to 350 Daltons, a number of rotatable bonds not greater than 7, and XlogP less than or equal to 3.5. We removed molecules containing charged...
One limitation of the method is the requirement for high quality, high molecular weight input DNA. This can be particularly challenging for plants that frequently contain common and species-specific secondary metabolites, which often interfere with downstream processes. Cape Primroses (genus Streptocarp...
Protein abundance was normalized to an overall abundance and a protein molecular weight, and log2-transformed. Missing intensities recorded as zero were converted to explicit missing values. Proteins were then ranked by their abundance in a target pulldown, by a difference in the abundance between ...
whereMis the molecular weight,ρis mass density, andNAis the Avogadro constant. The number of ENMs in the agglomerate (n) is represented using equation (2): $$n = \left( {\frac{{r_0}}{r_{\mathrm{w}}} \right)^3$$ (2) where...
Bioinformatic analyses Vector NTI Suite 7 [20] was used for ORF translation and molecular weight calculation of the deduced protein. BLAST [21] was performed on the NCBI server (http:// www.ncbi.nlm.nih.gov/BLAST). Multiple sequence align- ments and phylogenetic analysis were carried out ...
