“…These deconvoluted C1s spectra are shown in Fig. 4 (Kiehl et al, 2013). For the untreated coral-containing NFs, similar peaks as for the CS/PEO NFs can be seen, however, also an additional peak at the higher binding energy side located at 289.3 eV was required to obtain a good curve fit.…”

“…This observation is logic as this particular peak can be attributed to carbonate (CO3), which is the main constituent of coral (see Fig. 4 (b)) (Baltrusaitis, Usher, & Grassian, 2007;Borcia, Anderson, & Brown, 2003;Gerenser, 1987;Kiehl et al, 2013;Ni & Ratner, 2008;Silva et al, 2008). As it is shown in Fig.…”

“…Figure 2(d) presents the XPS survey spectrum of pBS. As shown, pBS possesses obvious C1s (287.5 eV), O1s (535.2 eV), B1s (193.4 eV), Si2s (156.2 eV) and Si2p (105.5 eV) peaks, [26][27][28] and the C, O, Si and B element contents are 52.6%, 33.5%, 11.2% and 2.7%, respectively (Table S1). In addition, SEM-EDS mapping was carried out to analyze the element content and distribution of pBS (Fig.…”

In this work, we first synthesized vinyl-terminated polyborosiloxane (pBS) filler, and then incorporated it into silicone rubber foam (SRF) matrix to prepare composite materials through a simple chemical dehydrogenative foaming method under ambient conditions. The pBS filler with reactive groups could form physical and chemical crosslinking networks in SRF, leading to an excellent dispersion level of pBS in the SRF matrix. Moreover, the inserted pBS could remarkably improve the mechanical and flame-retardancy properties of SRF-pBS composites. Intriguingly, the SRF-pBS6 foam containing 6 wt% of pBS possessed a uniform porous structure and balanced mechanical properties (⊞ b = 65.4 kPa, ε b = 56.7%, compression stress 97.1 kPa), thermal conductivity (0.102 W (m K) −1 ), limiting oxygen index (29.8%) and UL-94 rating (V-0) among the prepared foams. In addition, the incorporated pBS (6 wt%) could synergistically catalyze the formation of a silicon-boron strengthened ceramic-like protective layer under fire and was capable of suppressing heat and smoke production in the SRF-pBS6 foam. The present work provides a promising way for developing high mechanical and flame-retardant polymeric foam materials with good thermal insulation.

“…The results of spectrum decomposition of electrons from Ca 2p-level showed that calcium atoms in the near-surface layer of calcium particles exists only in one chemical state-natural calcium carbonate ( 8 1 . Decomposition of spectrum С 1s-level of carbon atoms was conducted with regard to four components with bond energies 284.80 eV, 286.07, 287.50 and 289.32 eV, the first three of them were referred to the presence of hydrocarbon pollutions as a part of the surface, and the last one-to surface carbonate mineral group [33,34].…”

Surface activation and induced change of physicochemical and process properties of galena by nanosecond electromagnetic pulses

et al. 2014

View full text Add to dashboard Cite

X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy are used to study the change of the surface layers and chemical state of atoms on galena surface after treatment by highvoltage nanosecond electromagnetic pulses. By XPS the induced structural changes of galena surface layer are associated with alteration of chemical state of sulfur atoms, which conditions the change of electrochemical and flotation properties of the semiconductor sulfide mineral: growth of electrode potential creates favorable conditions for adsorption of anion collector and promotes increased floatability of galena.
