A comprehensive study on the polycation charge and conformation poly(acrylamide-co-dimethyldiallylammonium chloride) with a moar mass of 250 kDa (comprising of 45 mass% of dimethyldiallylammonium chloride) has been performed in aqueous media without and with an electrolyte as a function of temperat...
In the present paper is given the results of investigation of secondary ions formation mechanisms from a surface of polymeric dielectrics. By calculation of secondary ions' relative yield in dielectric mass spectrum and the results comparison with various mechanisms, an attempt was made to explain...

What is the molecular geometry of SF6? What is the mass in grams of 2 molecules of CCl4? What is the molecular geometry of Co2? What is the name of the covalent compound CCl4? What is a trigonal planar? What is the molecular geometry of NO3?
To analyse the molecular content of the melanosome-like bodies, samples of grains were removed from the eye (as well as from other parts of the fossil and surrounding sediments) using a sterile scalpel, and subjected to ToF-SIMS analysis. The resulting mass spectra, which are formed by ...
Previously, pH-assisted selective sedimentation has been reported for the purification of GO nanosheets39,40. However, this method is not suitable for MOF and ZIF nanosheets due to their structural sensitivity toward pH values41. Recently, Coleman and co-workers revealed that good solvents for ...

The assemblies are characterized fully by NMR and electrospray ionization-mass spectroscopic (ESI-MS) analysis and in two cases the X-ray single-crystal structure analysis established the gross structures. The selective formation of a diimidazole-based linker (L) containing macrocycle [(en)Pd(µ-...
We monitored surface coverage by atomic force microscopy (AFM) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) (Fig. 3; Supplementary Figs 7–10). AFM data revealed homogenous coverage of the substrates (Fig. 3b; Supplementary Fig. 7) with the surface profile indicating a ...
The [ErL(H2O)] (NO3) complex was prepared from ligand L and Er(NO3)3.5H2O (ref. 22) and was fully characterized by elemental analysis, infrared spectroscopy, 1H-NMR and electrospray mass spectrometry (Supplementary Figs 1–4). The presence of the nitrate anions was particularly well ...
