Cleaved surfaces of natural anhydrite (CaSO4) crystal were observed with atomic force microscopy (AFM) before and after its partial dissolution in aqueous solutions of (NH4)2SO4. After the dissolution, rectangular etch pits were observed on the (010) face, which grew faster along the a-axis ...
Linear fatty acids, saturated or unsaturated, with an even number of carbon atoms from 8 to 20 inclusive and also behenic and ricinoleic acids and the NH4, Ca, Mg, K, Na, Al, Zn salts of these acids EurLex-2 The invention relates to a mixture for cleaning printed circuit boards con...
Here, the combined effects of thermal energy and electron beam irradiation are explored on the structural evolution of 2D MoS2 flakes through the thermal decomposition of a (NH4)(2)MoS4 precursor inside an ultrahigh vacuum (10(-9) Torr) scanning transmission electron microscope (STEM). The ...

By simply adjusting the doping quantity, the number of nanorings (NRs) was tuned from a multi-level ring (mSMO NRs) to a single ring (sSMO NRs). Taking advantage of the strong light absorption as well as the excellent polymer compatibility, the resulting sSMO NRs acted as photothermal ...
FG phase, not only isτc ~3-fold longer on average, but also the profile shows two distinct maxima. The maximum at the residues around P10 (Q9 and A11) can be explained by proline’s fixed φ angle (\(\varphi \approx -60^\circ\)), which limits the number of possible conformatio...
