A set of molecular salts with general formula [1H]nA·xH2O (1 = 4-amino-cinnamic acid, A(n-) = NO3(-), BF4(-), PF6(-), SO4(2-), x = 0, 1) was prepared and structurally characterized. [1H]Cl and [1H]2SO4·H2O(II) were found to undergo an SCSC stepwise [2+2] photodimerization, which was followed by X-ray diffraction; a kinetic analysis was performed on single crystals of both salts. In the case of ...

Human vaccines have used aluminium-based adjuvants (alum) for >80 years despite incomplete understanding of how alum enhances the immune response. Alum can induce the release of endogenous danger signals via cellular necrosis which elicits inflammation-associated cytokines resulting in humoral immunity. IL-33 is proposed to be one such danger signal that is released from necrotic cells. Therefo...

Sustainable chemistry is a relatively new field that aims to achieve both economic and environmental goals simultaneously. This paper discusses cleaner more sustainable method for dyeing cotton fabric using Direct Violet 09 Reactive 05 dye. It has been noticed good color characteristics were obtained when was dyed with 35 mL of microwave-treated dye solution 7 pH 2 g Aluminum sulfate 30 min at ...

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...
