Bis- and tris-Lewis acids, based on alkynylsilanes with terminal boron functions, were prepared tested for their ability to accept neutral Lewis base molecules.

The synthesis of tris(ortho-carboranyl)borane (BoCb3), a single site neutral Lewis superacid, in one pot from commercially available materials is achieved. high fluoride ion affinity (FIA) confirms its classification as superacid and the Gutmann-Beckett method well adducts with bases indicate stronger acidity over widely used fluorinated aryl boranes. electron withdrawing effect ortho-carborane...

Diaphorase Assay-Six-hundredths pmole of 2,6-dichlorophenolindophenol, 50 pmoles of Tris-HCl, pH 7.55, 1 pmole of EDTA, enzyme, and 0.44 pmole of DPNH in a volume of 3 ml were placed in a Beckman spectrophotometer equipped with a water jacket through which water at 25” was circulated. A control cuvette without enzyme was included, and absorbancy at 600 rnp was determined for 10 minutes. Under t...

Metastasis is the primary cause of death in breast cancer patients. Early detection of high-risk breast cancer, including micrometastasis, is critical in tailoring appropriate and effective interventional therapies. Increased fibronectin expression, a hallmark of epithelial-to-mesenchymal transition, is associated with high-risk breast cancer and metastasis. We have previously developed a penta...

Au(III); Tris(hydroxymethyl)aminomethane; Modified activated carbon; Adsorption; Batch method Abstract In the current study, a sensitive and simple method for selective separation of gold, Au(III), from water samples prior to its determination by inductively coupled plasma-optical emission spectrometry (ICP-OES), was investigated. The method utilized activated carbon modified with tris(hydroxym...
