In this study, we explore the dyeing properties of extract sappan wood natural dye for coloration wool yarn to find potential use dyed in development eco-friendly textiles. Different characterizations were used know chemistry and its interaction with metal salts wool. Interestingly, found that salts, which are called as mordants reference unmordanted sample, play an important role fixing molecu...

Abstract The (early) hydration mechanisms of two different binder systems used for shotcrete were investigated: the so far almost unexplored low sulfate (spray binder), in field dry-mix shotcrete; and ordinary Portland cement, accelerated by aluminum sulfate, widely wet-mix shotcrete. basis fast setting spray is rapid dissolution C 3 A subsequent formation flaky CO -AFm phases. Thereby induced ...

The very early hydration behavior of a hydraulic binder phase, ye’elimite, Ca4Al6O12SO4, in the absence and presence calcium sulfate, has been investigated. A time-resolved situ multinuclear magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopic suite involving 1H 27Al MAS as well two-dimensional multiple quantum (MQMAS) experiments employed to detect transient species govern...

A stability-indicating high-performance thin-layer chromatographic (HPTLC) method has been developed for the determination of terbutaline sulfate (TBS) as a bulk drug and in pharmaceutical formulations (submicronized dry powder inhalers). The separation was achieved on TLC aluminum plates precoated with silica gel 60F-254 using chloroform-methanol (9.0:1.0 v/v) as mobile phase. The densitometri...

In this study, a novel flocculant was prepared by an inorganic polymetric flocculant (IPF) polysilicate ferroaluminum sulfate (PSFA) and rectorite (REC). The structure of the PSFA-REC composite was characterized by Fourier transform infrared (FT-IR) spectroscopy and X-ray diffraction (XRD), in order to determine the optimal temperature. The flocculation test was made at 25 , 45 and 65 , the res...
