Synthesis of Chemically Modified Acid-Functionalized Multiwall Carbon Nanotubes with Benzimidazole for Removal of Lead and Cadmium Ions from Wastewater.

In this work, acid-functionalized multiwalled carbon (MWCNTs-COH) nanotube was successfully functionalized with a heterocyclic scaffold, namely benzimidazole, to give novel functionalized multiwalled carbon nanotubes (BI@MWCNTs). Then, FTIR, XRD, TEM, EDX, Raman spectroscopy, DLS, and BET analyses were used to characterize the synthesized BI@MWCNTs. The effectiveness of the adsorption of two heavy metal ions, Cd and Pb, in single metal and mixed metal solutions on the prepared material was investigated.

Synthesis, Anticancer, Antioxidant, Anti-Inflammatory, Antimicrobial Activities, Molecular Docking, and DFT Studies of Sultams Derived from Saccharin.

A series of -substituted saccharins namely 2-(1,1-dioxido-3-oxobenzo[d]isothiazol-2()-yl) acetonitrile () and (alkyl 1,1-dioxido-3-oxobenzo[d]isothiazol-2(3)-yl) acetate (-) were synthesized, in moderate to excellent yields, from commercially available starting materials by two different approaches and their chemical structures were characterized by spectroscopic techniques (H-NMR, C-NMR, IR, and MS). All the synthesized compounds were evaluated for their anti-inflammatory toward IL-6 and TNF-α, antioxidant, as well as their anticancer activities against hepatic cancer cells. In addition, their anti-fungal and antibacterial activities against both Gram-positive and Gram-negative bacteria were tested.

Bimetallic nickel/manganese phosphate-carbon nanofiber electrocatalyst for the oxidation of formaldehyde in alkaline medium.

The development of earth-abundant transition metal-based catalysts, supported by a conductive carbonaceous matrix, has received great attention in the field of conversion of formaldehyde derivatives into toxic-free species. Herein, we report a comprehensive investigation of bimetallic electrocatalyst activity towards the electrooxidation of formaldehyde. The bimetallic phosphate catalyst is prepared by co-precipitation of Ni and Mn phosphate precursors using a simple reflux approach.

Synthesis, antimicrobial, DNA cleavage and antioxidant activities of tricyclic sultams derived from saccharin.

Two series of fused tricyclic sultams (carboxylates, 3a, b and 5a, f, g and anilides 5b-e) were synthesized from saccharin and their chemical structures were confirmed by spectroscopic tools. Then, their antibacterial activities and MIC were evaluated against two strains of gram positive and gram-negative bacteria. The MIC values of the tested compounds are in the of range 8-33 μg/ml.
