Sentence examples for molecular weight reducing from inspiring English sources

When radiation is used, the polymer may undergo one or both of the two possible reactions: those that are molecular weight increasing in nature, or molecular weight reducing in nature.

LPMO (GH61) catalyze the oxidative cleavage of cellulose using low molecular weight reducing agents such as ascorbate, gallate, reduced glutathione, and even lignin [ 12].

These copper-dependent enzymes were shown to cleave cellulose by an oxidative mechanism provided that reduction equivalents from CDH or low molecular weight reducing agents (e.g. ascorbate) are available [ 2- 4].

Typically, Phase I activates the chemical by introducing a reactive and polar functional group, whereas Phase II conjugates the activated chemical with a charged species, increasing the molecular weight, reducing reactivity, and improving the transport property.

At the same time, according to [26], the addition of lithium salt LiPF6 in a PEO with high molecular weight reduces both glass transition temperature and melting point.

The molecular weight, reduced by two atomic mass units (Table 1), was consistent with a replacement of fluorine by a hydroxyl group.

The addition of nanoparticles of low molecular weight PLGA to those of high molecular weight reduced the release rate at the initial release phase, but that at the second release phase was almost entirely unaffected by mixing ratio.

All scaffolds, regardless of molecular weight, reduced in size following hydration at concentrations lower than 2% wt/v.

When sonication is applied, the decrease in molecular weight reduces the number per chain of hydrogen bonding sites leading, at the same time, to a reduction of the intermolecular hydrogen bonding between polymer molecules, that is, the attractions between guar chains [ 12]. k H is also very sensitive to the formation of molecular aggregates.

Only low-molecular weight oligomer was obtained when hydroquinone (HQ) was employed as comonomer, while copolymerization of DFK, SHQ, and phenolphthalein (PL) proceeded quantitatively to high-molecular weight (reduced viscosities above 0.68 dL/g) in dimethylsulfoxide at 175 °C in presence of anhydrous potassium carbonate.

The oxidative cleavages of cellulose catalysed by AA9 enzymes require reducing equivalents generated by the AA3_1 enzyme or alternatively low-molecular-weight reducing agents [ 8, 12].
