A different application of PRISM leads to an accurate relation between the monomer and centre-of-mass pair correlation functions in both polymer solutions and melts,31 as already referred to in Section 12.2. The key idea is to consider the centre of mass of each polymer i as an additional, ...
Whether or not the decreasing amplitudes of the Pb isotopic excursions are driven by decreasing outflow intensities or rather reflect different water mass sourcing for each event cannot be answered with the available data. The formation of the runoff Pb isotopic signal is a complex process, which ...
Two different PLA's were used for composites production and were analyzed through thermogravimetric analysis (TGA), rheological behavior, and molar mass characterization. The effect of Biosilicate® addition on PLA matrices by this type of processing is promising for the preparation of filaments to ...
However, a double molar mass distribution was also observed on Cole–Cole plots, indicating that there is also a chain recombination mechanism competing with the chain scission mechanism. PLA hydrolysis was observed by infra-red spectroscopy, where acid characteristic peaks appeared and became more ...
Interestingly, HC1 exhibited the highest degradation rate via chain scission in the backbone, possibly due to its high permeability and molecular weight (Figure 10). As monitored by GPC, HC1 had a satisfactory decrease in molar mass from 78,800 to about 45,700 g/mol after only 60 days of ...
The liquid state processing route is the most practical method in term of mass production and low production cost. The liquid state processing can be applied by using different methods such as melt gas injection [9], entrapped gas expansion [10], casting using a polymer or wax [11], and ...
The ACQUITY PDA detector (190–400 nm, resolution 1.2 nm) of the system was used to monitor the elution of the polymers, sulfamerazine, and telmisartan at wavelengths of 210 nm, 250 nm, and 295 nm, respectively, using THF as the mobile phase at a flow rate of 0.9 mL min−1. The ...
This work presents a facile preparation method that is suitable for mass production and the application of membranes to be used as air filters for highly efficient filtration of PM2.5. Keywords: PM2.5; zeolite imidazole framework-8 (ZIF-8), melt-blown; electrospinning 1. Introduction In recent ...
