The two monomers 2,4-dicyanobut-1-ene and isoprene undergo spontaneous copolymerization when mixed together. A more controlled set of solution copolymerizations have been carried out in toluene to low conversions (< 4%), and analysis of the data gave monomer reactivity ratios of r1, (DCB) =...

Machine intelligence accelerated design of conductive MXene aerogels with programmable properties Machine learning-assisted robots produce MXene aerogels containing cellulose, gelatin, and glutaraldehyde, fabricating 162 compositions. Inverse design from resulting properties affords tailored compression-stable materia...
Structural isomers have the same molecular formula but a different bonding arrangement among the atoms. ... The simplest forms of stereoisomers are cis and trans isomers, both of which are created by the restricted rotation about a double bond or ring system.What...
Functional group isomerism- structural isomers with the same molecular formula, but with atoms connected differently so dissimilar functional groups are formed. Structural Isomer Examples Butane and isobutane (C4H10) are structural isomers of each other. ...
‘noise peaks’ was gathered from the fragmentation spectra, using all peaks that did not have a molecular subformula decomposition of the known molecular formula of the precursor. For each spectrum,α nof these ‘noise peaks’ were added to the spectrum, wherenis the number of peaks in ...
On the contrary, regarding the BO values for the C atoms, the C16 and C17 atoms in αα-trehalose and the C17 atoms in αβ and ββ-trehalose and the C14 and C19 atoms in the dihydrated species present the higher values in gas phase but, some of these values change few in ...
1). Thus, brain age estimates from DBN may be derived quickly and automatically, with less intensive preprocessing and quality assessments than required for other brain age models or established MRI biomarkers. With this method, we modeled the emergence of advanced structural brain aging over the ...
The definition of synergy used in these studies was the fractional inhibitory concentration (FIC) index, represented by the formula FIC= (MIC of fosfomycin in combination/MIC of fosfomycin alone) + (MIC of SF2312 in combination/MIC of the SF2312 alone). A calculated FIC index of less than ...
For calculation of the percent change in TEWL, the following formula was used: {(TEWL stripped area at indicated time/TEWL control area at indicated time)/(TEWL stripped area before stripping/TEWL control area before stripping)-1} × 100%. Surface pH was measured using a Skin-pH-Meter (PH...
