A novel one-pot, three-component synthesis of N-acyl or N-carbamoyl-alpha-amidosulfides 4 is described. The three-component reaction of aldehydes 1, primary carbamates (or amides) 2 and phenylsulfinic acid (6a) afforded alpha-amidosulfones 7, which after a ...
The effect of CuCl2 and EDTA on increasing the sensitivity of enzyme biosensors was evaluated. The experiments revealed that successive exposure of these solutions to our biosensors can increase the sensitivity of the glucose and lactate biosensors up to 8 ...
It is known that the addition of supplementary cementitious materials (SCMs) in concretes reduces or even stops expansion due to alkali silica reaction (ASR). It has been widely shown that the main mechanism controlling ASR in blends is the alkali fixation ...
Caught in a trap! Fluorimetric chloride sensing in water is achieved by exploiting the changes in partition constant of a receptor complex in its bound and nonbound states. In the presence of chloride, the complex preferentially resides in the micelle pseu ...
A dyestuff shown by the formula (1), ML 1 L 2 L 3 (1) wherein M represents an element belonging to Group 8 to Group 10 of the long format Periodic Table, L 1 and L 2 individually represent a bidentate ligand shown by the formula (2), L 3 represents a biden ...
Medium sized molecules endowed with multiple Gd3+ complexes are efficient high magnetic field MRI contrast agents. The novel ligand Mes(DO3A)3, presenting three DO3A (1,4,7,10-tetraazacyclododecane-N,N′,N′′-triacetatic acid) units grafted on the methyl pos ...
A novel ruthenium(II) compound, trans-cis-cis-[Ru(II)Cl-2(DMSO)(2)(2-amino-5-methyl-thiazole)(2)], (I), PMRu52 hereafter, that may be obtained from the previously described (cis and trans)[Ru(II)Cl-2(DMSO)(4)] complexes, was designed, synthesized and chara ...
Chloride ion is in part bound into ordinary Portland cement paste and modifies its mineralogy. To understand this a literature review of its impacts has been made and new experimental data were obtained. Phase pure preparations of Friedel's salt, Ca4Al2(Cl ...
High aspect ratio silicon wire arrays with excellent pattern fidelity over wafer-scale area were grown by chemical vapor deposition at moderate temperature, using a gas mixture of silane and hydrogen chloride. An innovative two-step process was developed f ...
The recognition and sensing of aqueous chloride by synthetic receptors is a challenging task. Herein we apply the chemosensing ensemble methodology to optically detect chloride in water at near physiological pH. Variants based on two closely related recept ...
